++ GNU libc SNAPSHOT SYSTEM
++ (general info)
++ Updated 1997-9-26
++
++WHAT ARE GNU libc SNAPSHOTS
++---------------------------
++
++Snapshots are an "image" of the main glibc development tree, captured at a
++particular random instant in time. When you use the snapshots, you should be
++able to maintain a local copy of libc that is no more than one day older than
++the official source tree used by the libc maintainers.
++
++The primary purpose of providing snapshots is to widen the group of motivated
++developers that would like to help test, debug, and enhance glibc, by providing
++you with access to the "latest and greatest" source. This has several
++advantages, and several disadvantages.
++
++ First the advantages:
++
++ o Once we have a large base of motivated testers using the snapshots,
++ this should provide good coverage across all currently supported
++ glibc hosts and targets. If a new bug is introduced in glibc due to
++ fixing another bug or ongoing development, it should become
++ obvious much more quickly and get fixed before the next general
++ net release. This should help to reduce the chances of glibc being
++ released to the general public with a major bug that went unnoticed
++ during the release cycle testing because they are machine dependent.
++ We hope to greatly improve glibc's stability and reliability by
++ involving more people and more execution environments in the
++ prerelease testing.
++
++ o With access to the latest source, any diffs that you send to fix
++ bugs or add new features should be much easier for the glibc team
++ to merge into the official source base (after suitable review
++ of course). This encourages us to merge your changes quicker,
++ while they are still "fresh".
++
++ o Once your diffs are merged, you can obtain a new copy of glibc
++ containing your changes almost immediately. Thus you do not
++ have to maintain local copies of your changes for any longer
++ than it takes to get them merged into the official source base.
++ This encourages you to send in changes quicker.
++
++ And the disadvantages:
++
++ o The snapshot you get will be largely untested and of unknown quality.
++ It may fail to configure or compile. It may have serious bugs.
++ You should always keep a copy of the last known working version
++ before updating to the current snapshot, or at least be able to
++ regenerate a working version if the latest snapshot is unusable
++ in your environment for some reason.
++
++ If a production version of glibc has a bug and a snapshot has the fix,
++ and you care about stability, you should put only the fix for that
++ particular problem into your production version. Of course, if you
++ are eager to test glibc, you can use the snapshot versions in your
++ daily work, but users who have not been consulted about whether they
++ feel like testing glibc should generally have something which is at
++ least as bug free as the last released version.
++
++ o Providing timely response to your questions, bug reports, and
++ submitted patches will require the glibc development team to allocate
++ time from an already thin time budget. Please try to help us make
++ this time as productive as possible. See the section below about
++ how to submit changes.
++
++
++WHO SHOULD TRY THE SNAPSHOTS
++----------------------------
++
++Remember, these are snapshots not tested versions. So if you use
++these versions you should be able to
++
++ o make sure your system stays usable
++
++ o locate and hopefully fix problems
++
++ o to port glibc to a new target yourself
++
++You should not use the snapshots if
++
++ o your system is needed in a production environment which needs
++ stability
++
++ o you expect us to fix your problems since you somehow depend on them.
++ You must be willing to fix the problems yourself, we don't want to
++ see "I have problems, fix this" messages.
++
++
++HOW TO GET THE SNAPSHOTS
++------------------------
++
++At the moment we provide a full snapshot weekly (every sunday), so
++that users getting a snapshot for the first time, or updating after
++a long period of not updating, can get the latest version in a single
++operation. Along with the full snapshot, we will provide incremental
++diffs on a nearly daily basis (whenever code changes). Each daily
++diff will be relative to the source tree after applying all previous
++daily diffs. The daily diffs are for people who have relatively low
++bandwidth ftp or uucp connections.
++
++The files will be available via anonymous ftp from alpha.gnu.org, in
++directory /gnu/libc and on linux.kernel.org in /pub/software/libs/glibc. The
++directories should look something like:
++
++ libc-970921.tar.gz
++ libc-970917-970922.diff.gz
++ libc-970922-970925.diff.gz
++ .
++ .
++ .
++
++Please note that the snapshots on alpha.gnu.org and on
++linux.kernel.org are not always in sync. Patches to some files might
++appear a day a diff earlier or later on alpha than on kernel.
++Use always alpha or always kernel but don't mix them.
++
++There are sometimes additionally test releases of the add-ons available in
++these directories. If a new version of an add-on is available it is normally
++required for the corresponding snapshot so always pay attention for these.
++
++Note that we provide GNU gzip compressed files only. You can ftp gzip
++from ftp.gnu.org in directory pub/gnu.
++
++In some cases the dates for diffs and snapshots do not match like in the
++example above. The full release is for 970921 but the patch is for
++970917-970922. This only means that nothing changed between 970917 and 970922
++and that you have to use this patch on top of the 970921 snapshot since the
++patch is made on 970922.
++
++Also, as the gcc developers did with their gcc snapshot system, even though we
++will make the snapshots available on a publically accessible ftp area, we ask
++that recipients not widely publicise their availability. The motivation for
++this request is not to hoard them, but to avoid the situation where the
++general glibc user base naively attempts to use the snapshots, has trouble with
++them, complains publically, and the reputation of glibc declines because of a
++perception of instability or lack of quality control.
++
++
++GLIBC TEST SUITE
++----------------
++
++A test suite is distributed as an integral part of the snapshots. A simple
++"make check" in your build directory is sufficient to run the tests. glibc
++should pass all tests and if any fails, please report it. A failure might not
++originate from a bug in glibc but also from bugs in the tools, e.g. with gcc
++2.7.2.x the math tests fail some of the tests because of compiler bugs.
++
++Note that the test suite is still in its infancy. The tests themselves only
++cover a small portion of libc features, and where tests do exist for a feature
++they are not exhaustive. New tests are welcome.
++
++
++GETTING HELP, GLIBC DISCUSSIONS, etc
++------------------------------------
++
++People who want to help with glibc and who test out snapshots
++regularly should get on the libc-alpha@sourceware.cygnus.com mailing
++list by sending an email to libc-alpha-subscribe@sourceware.cygnus.com.
++This list is meant (as the name suggests) for the discussion of test
++releases and also reports for them. People who are on this list are
++welcome to post questions of general interest.
++
++People who are not only willing to test the snapshots but instead
++really want to help developing glibc should contact
++libc-hacker-subscribe@sourceware.cygnus.com.org to be put on the developers
++mailing list. This list is really only meant for developers. No
++questions about installation problems or other simple topics are
++wanted nor will they be answered.
++
++Do *not* send any questions about the snapshots or patches specific to the
++snapshots to bug-glibc@gnu.org. Nobody there will have any idea what
++you are talking about and it will just cause confusion.
++
++
++BUG REPORTS
++-----------
++
++Send bug reports directly to Ulrich Drepper <drepper@gnu.org>. Please
++do *not* use the glibcbug script for reporting bugs in the snapshots.
++glibcbug should only be used for problems with the official released versions.
++We don't like bug reports in the bug database because otherwise the impression
++of instability or lack of quality control of glibc as a whole might manifest
++in people's mind.
++
++Note that since no testing is done on the snapshots, and snapshots may even be
++made when glibc is in an inconsistent state, it may not be unusual for an
++occasional snapshot to have a very obvious bug, such as failure to compile on
++*any* machine. It is likely that such bugs will be fixed by the next
++snapshot, so it really isn't necessary to report them unless they persist for
++a couple of days.
++
++Missing files should always be reported, since they usually mean there is a
++problem with the snapshot-generating process and we won't know about them
++unless someone tells us.
++
++Bugs which are non-obvious, such as failure to compile on only a specific
++machine, a new machine dependent or obscure bug (particularly one not detected
++by the testsuite), etc should be reported when you discover them, or have a
++suggested patch to fix them.
++
++
++FORMAT FOR PATCHES
++------------------
++
++If you have a fix for a bug, or an enhancement to submit, send your patch to
++Ulrich Drepper <drepper@gnu.org>. Here are some simple guidelines for
++submitting patches:
++
++ o Use "unified diffs" for patches. A typical command for generating
++ context diffs is "diff -ru glibc-old glibc-patched".
++
++ o Use the "minimalist approach" for patches. That is, each patch
++ should address only one particular bug, new feature, etc. Do not
++ save up many unrelated changes and submit them all in one big
++ patch, since in general, the larger the patch the more difficult
++ it is for us to decide if the patch is either correct or
++ desirable. And if we find something about the patch that needs
++ to be corrected before it can be installed, we would have to reject
++ the entire patch, which might contain changes which otherwise would
++ be accepted if submitted separately.
++
++ o Submit a sample ChangeLog entry with your patch. See the existing
++ glibc ChangeLog for examples of what a ChangeLog entry should look
++ like. The emacs command ^X4A will create a ChangeLog entry header
++ for you.
++
++
++BUILDING SNAPSHOTS
++------------------
++
++The `best' way to build glibc is to use an extra directory, e.g.:
++tar xzf libc-970921.tar.gz
++mkdir build-glibc
++cd build-glibc
++../libc-970921/configure ...
++
++In this way you can easily clean up (since `make clean' doesn't work at
++the moment) and rebuild glibc.
++
++
++NECESSARY TOOLS
++---------------
++
++For the recommended versions of gcc, binutils, make, texinfo, gettext,
++autoconf and other tools which might be especially needed when using patches,
++please read the file INSTALL.
++
++
++HOW CAN YOU HELP
++----------------
++
++It helps already a lot if you just install glibc on your system and try to
++solve any problems. You might want to look at the file `PROJECTS' and help
++with one of those projects, fix some bugs (see `BUGS' or the bug database),
++port to an unsupported platform, ...
++
++
++FURTHER DOCUMENTATION
++---------------------
++
++A lot of questions are answered in the FAQ. The files `INSTALL', `README' and
++`NOTES' contain the most important documentation. Furthermore glibc has its
++own 700+ pages info documentation, ...
++
++
++
++And finally a word of caution: The libc is one of the most fundamental parts
++of your system - and these snapshots are untested and come without any
++guarantee or warranty. You might be lucky and everything works or you might
++crash your system. If you install a glibc snapshot as primary library, you
++should have a backup somewhere.
++
++On many systems it is also a problem to replace the libc while the system is
++running. In the worst case on broken OSes some systems crash. On better
++systems you can move the old libc aside but removing it will cause problems
++since there are still processes using this libc image and so you might have to
++check the filesystem to get rid of the libc data. One good alternative (which
++is also safer) is to use a chroot'ed environment.
++
++Thanks for your help and support.
++
++Thanks to Fred Fish from Cygnus for the original version of this text
++(for GDB).

++This directory contains the version VERSION release of the GNU C Library.
++Many bugs have been fixed since the last release.
++Some bugs surely remain.
++
++As of this release, the GNU C library is known to run on the following
++configurations:
++
++ *-*-gnu GNU Hurd
++ i[3456]86-*-linux-gnu Linux-2.x on Intel
++ m68k-*-linux-gnu Linux-2.x on Motorola 680x0
++ alpha*-*-linux-gnu Linux-2.x on DEC Alpha
++ powerpc-*-linux-gnu Linux and MkLinux on PowerPC systems
++ powerpc64-*-linux-gnu Linux-2.4.19+ on 64-bit PowerPC systems
++ sparc-*-linux-gnu Linux-2.x on SPARC
++ sparc64-*-linux-gnu Linux-2.x on UltraSPARC 64-bit
++ arm-*-none ARM standalone systems
++ arm-*-linux Linux-2.x on ARM
++ arm-*-linuxaout Linux-2.x on ARM using a.out binaries
++ mips*-*-linux-gnu Linux-2.x on MIPS
++ ia64-*-linux-gnu Linux-2.x on ia64
++ s390-*-linux-gnu Linux-2.x on IBM S/390
++ s390x-*-linux-gnu Linux-2.4+ on IBM S/390 64-bit
++ sh-*-linux-gnu Linux-2.x on Super Hitachi
++ cris-*-linux-gnu Linux-2.4+ on CRIS
++ x86-64-*-linux-gnu Linux-2.4+ on x86-64
++
++Former releases of this library (version 1.09.1 and perhaps earlier
++versions) used to run on the following configurations:
++
++ alpha-dec-osf1
++ i[3456]86-*-bsd4.3
++ i[3456]86-*-isc2.2
++ i[3456]86-*-isc3
++ i[3456]86-*-sco3.2
++ i[3456]86-*-sco3.2v4
++ i[3456]86-*-sysv
++ i[3456]86-*-sysv4
++ i[3456]86-force_cpu386-none
++ i[3456]86-sequent-bsd
++ i960-nindy960-none
++ m68k-hp-bsd4.3
++ m68k-mvme135-none
++ m68k-mvme136-none
++ m68k-sony-newsos3
++ m68k-sony-newsos4
++ m68k-sun-sunos4
++ mips-dec-ultrix4
++ mips-sgi-irix4
++ sparc-sun-solaris2
++ sparc-sun-sunos4
++
++Since no one has volunteered to test and fix the above configurations,
++these are not supported at the moment. It's expected that these don't
++work anymore. Porting the library is not hard. If you are interested
++in doing a port, please contact the glibc maintainers by sending
++electronic mail to <bug-glibc@gnu.org>.
++
++There are some add-ons which can be used together with GNU libc. They
++are designed in a way to ease the installation by integrating them in
++the libc source tree. Simply get the add-ons you need and use the
++--enable-add-ons option of the `configure' script to tell where the
++add-ons are found. Please read the FAQ file for more details.
++
++See the file INSTALL to find out how to configure, build, install, and port
++the GNU C library. You might also consider reading the WWW pages for the
++GNU libc at http://www.gnu.org/software/libc/libc.html.
++
++The GNU C Library is completely documented by the Texinfo manual found
++in the `manual/' subdirectory. The manual is still being updated and
++contains some known errors and omissions; we regret that we do not
++have the resources to work on the manual as much as we would like.
++Please send comments on the manual to <bug-glibc-manual@gnu.org>, and
++not to the library bug-reporting address.
++
++The file NOTES contains a description of the feature-test macros used
++in the GNU C library, explaining how you can tell the library what
++facilities you want it to make available.
++
++We prefer to get bug reports sent using the `glibcbug' shell script which
++is installed together with the rest of the GNU libc to <bugs@gnu.org>.
++Simply run this shell script and fill in the information. Nevertheless
++you can still send bug reports to <bug-glibc@gnu.org> as normal electronic
++mails.
++
++The GNU C Library is free software. See the file COPYING.LIB for copying
++conditions, and LICENSES for notices about a few contributions that require
++these additional notices to be distributed.

+-
+-/* @r{This program uses the same features as example 2, and uses options and
+- arguments.
+-
+- We now use the first four fields in ARGP, so here's a description of them:
+- OPTIONS -- A pointer to a vector of struct argp_option (see below)
+- PARSER -- A function to parse a single option, called by argp
+- ARGS_DOC -- A string describing how the non-option arguments should look
+- DOC -- A descriptive string about this program; if it contains a
+- vertical tab character (\v), the part after it will be
+- printed *following* the options
+-
+- The function PARSER takes the following arguments:
+- KEY -- An integer specifying which option this is (taken
+- from the KEY field in each struct argp_option), or
+- a special key specifying something else; the only
+- special keys we use here are ARGP_KEY_ARG, meaning
+- a non-option argument, and ARGP_KEY_END, meaning
+- that all arguments have been parsed
+- ARG -- For an option KEY, the string value of its
+- argument, or NULL if it has none
+- STATE-- A pointer to a struct argp_state, containing
+- various useful information about the parsing state; used here
+- are the INPUT field, which reflects the INPUT argument to
+- argp_parse, and the ARG_NUM field, which is the number of the
+- current non-option argument being parsed
+- It should return either 0, meaning success, ARGP_ERR_UNKNOWN, meaning the
+- given KEY wasn't recognized, or an errno value indicating some other
+- error.
+-
+- Note that in this example, main uses a structure to communicate with the
+- parse_opt function, a pointer to which it passes in the INPUT argument to
+- argp_parse. Of course, it's also possible to use global variables
+- instead, but this is somewhat more flexible.
+-
+- The OPTIONS field contains a pointer to a vector of struct argp_option's;
+- that structure has the following fields (if you assign your option
+- structures using array initialization like this example, unspecified
+- fields will be defaulted to 0, and need not be specified):
+- NAME -- The name of this option's long option (may be zero)
+- KEY -- The KEY to pass to the PARSER function when parsing this option,
+- *and* the name of this option's short option, if it is a
+- printable ascii character
+- ARG -- The name of this option's argument, if any
+- FLAGS -- Flags describing this option; some of them are:
+- OPTION_ARG_OPTIONAL -- The argument to this option is optional
+- OPTION_ALIAS -- This option is an alias for the
+- previous option
+- OPTION_HIDDEN -- Don't show this option in --help output
+- DOC -- A documentation string for this option, shown in --help output
+-
+- An options vector should be terminated by an option with all fields zero.} */

+-Non-reentrant Conversion Function
+-=================================
+-
+- The functions described in the previous chapter are defined in
+-Amendment 1 to ISO C90, but the original ISO C90 standard also
+-contained functions for character set conversion. The reason that
+-these original functions are not described first is that they are almost
+-entirely useless.
+-
+- The problem is that all the conversion functions described in the
+-original ISO C90 use a local state. Using a local state implies that
+-multiple conversions at the same time (not only when using threads)
+-cannot be done, and that you cannot first convert single characters and
+-then strings since you cannot tell the conversion functions which state
+-to use.
+-
+- These original functions are therefore usable only in a very limited
+-set of situations. One must complete converting the entire string
+-before starting a new one, and each string/text must be converted with
+-the same function (there is no problem with the library itself; it is
+-guaranteed that no library function changes the state of any of these
+-functions). *For the above reasons it is highly requested that the
+-functions described in the previous section be used in place of
+-non-reentrant conversion functions.*

+-Non-reentrant Conversion of Single Characters
+----------------------------------------------
+-
+- - Function: int mbtowc (wchar_t *restrict RESULT, const char *restrict
+- STRING, size_t SIZE)
+- The `mbtowc' ("multibyte to wide character") function when called
+- with non-null STRING converts the first multibyte character
+- beginning at STRING to its corresponding wide character code. It
+- stores the result in `*RESULT'.
+-
+- `mbtowc' never examines more than SIZE bytes. (The idea is to
+- supply for SIZE the number of bytes of data you have in hand.)
+-
+- `mbtowc' with non-null STRING distinguishes three possibilities:
+- the first SIZE bytes at STRING start with valid multibyte
+- characters, they start with an invalid byte sequence or just part
+- of a character, or STRING points to an empty string (a null
+- character).
+-
+- For a valid multibyte character, `mbtowc' converts it to a wide
+- character and stores that in `*RESULT', and returns the number of
+- bytes in that character (always at least 1 and never more than
+- SIZE).
+-
+- For an invalid byte sequence, `mbtowc' returns -1. For an empty
+- string, it returns 0, also storing `'\0'' in `*RESULT'.
+-
+- If the multibyte character code uses shift characters, then
+- `mbtowc' maintains and updates a shift state as it scans. If you
+- call `mbtowc' with a null pointer for STRING, that initializes the
+- shift state to its standard initial value. It also returns
+- nonzero if the multibyte character code in use actually has a
+- shift state. *Note Shift State::.
+-
+- - Function: int wctomb (char *STRING, wchar_t WCHAR)
+- The `wctomb' ("wide character to multibyte") function converts the
+- wide character code WCHAR to its corresponding multibyte character
+- sequence, and stores the result in bytes starting at STRING. At
+- most `MB_CUR_MAX' characters are stored.
+-
+- `wctomb' with non-null STRING distinguishes three possibilities
+- for WCHAR: a valid wide character code (one that can be translated
+- to a multibyte character), an invalid code, and `L'\0''.
+-
+- Given a valid code, `wctomb' converts it to a multibyte character,
+- storing the bytes starting at STRING. Then it returns the number
+- of bytes in that character (always at least 1 and never more than
+- `MB_CUR_MAX').
+-
+- If WCHAR is an invalid wide character code, `wctomb' returns -1.
+- If WCHAR is `L'\0'', it returns `0', also storing `'\0'' in
+- `*STRING'.
+-
+- If the multibyte character code uses shift characters, then
+- `wctomb' maintains and updates a shift state as it scans. If you
+- call `wctomb' with a null pointer for STRING, that initializes the
+- shift state to its standard initial value. It also returns
+- nonzero if the multibyte character code in use actually has a
+- shift state. *Note Shift State::.
+-
+- Calling this function with a WCHAR argument of zero when STRING is
+- not null has the side-effect of reinitializing the stored shift
+- state _as well as_ storing the multibyte character `'\0'' and
+- returning 0.
+-
+- Similar to `mbrlen' there is also a non-reentrant function that
+-computes the length of a multibyte character. It can be defined in
+-terms of `mbtowc'.
+-
+- - Function: int mblen (const char *STRING, size_t SIZE)
+- The `mblen' function with a non-null STRING argument returns the
+- number of bytes that make up the multibyte character beginning at
+- STRING, never examining more than SIZE bytes. (The idea is to
+- supply for SIZE the number of bytes of data you have in hand.)
+-
+- The return value of `mblen' distinguishes three possibilities: the
+- first SIZE bytes at STRING start with valid multibyte characters,
+- they start with an invalid byte sequence or just part of a
+- character, or STRING points to an empty string (a null character).
+-
+- For a valid multibyte character, `mblen' returns the number of
+- bytes in that character (always at least `1' and never more than
+- SIZE). For an invalid byte sequence, `mblen' returns -1. For an
+- empty string, it returns 0.
+-
+- If the multibyte character code uses shift characters, then `mblen'
+- maintains and updates a shift state as it scans. If you call
+- `mblen' with a null pointer for STRING, that initializes the shift
+- state to its standard initial value. It also returns a nonzero
+- value if the multibyte character code in use actually has a shift
+- state. *Note Shift State::.
+-
+- The function `mblen' is declared in `stdlib.h'.

+-Non-reentrant Conversion of Strings
+------------------------------------
+-
+- For convenience the ISO C90 standard also defines functions to
+-convert entire strings instead of single characters. These functions
+-suffer from the same problems as their reentrant counterparts from
+-Amendment 1 to ISO C90; see *Note Converting Strings::.
+-
+- - Function: size_t mbstowcs (wchar_t *WSTRING, const char *STRING,
+- size_t SIZE)
+- The `mbstowcs' ("multibyte string to wide character string")
+- function converts the null-terminated string of multibyte
+- characters STRING to an array of wide character codes, storing not
+- more than SIZE wide characters into the array beginning at WSTRING.
+- The terminating null character counts towards the size, so if SIZE
+- is less than the actual number of wide characters resulting from
+- STRING, no terminating null character is stored.
+-
+- The conversion of characters from STRING begins in the initial
+- shift state.
+-
+- If an invalid multibyte character sequence is found, the `mbstowcs'
+- function returns a value of -1. Otherwise, it returns the number
+- of wide characters stored in the array WSTRING. This number does
+- not include the terminating null character, which is present if the
+- number is less than SIZE.
+-
+- Here is an example showing how to convert a string of multibyte
+- characters, allocating enough space for the result.
+-
+- wchar_t *
+- mbstowcs_alloc (const char *string)
+- {
+- size_t size = strlen (string) + 1;
+- wchar_t *buf = xmalloc (size * sizeof (wchar_t));
+-
+- size = mbstowcs (buf, string, size);
+- if (size == (size_t) -1)
+- return NULL;
+- buf = xrealloc (buf, (size + 1) * sizeof (wchar_t));
+- return buf;
+- }
+-
+-
+- - Function: size_t wcstombs (char *STRING, const wchar_t *WSTRING,
+- size_t SIZE)
+- The `wcstombs' ("wide character string to multibyte string")
+- function converts the null-terminated wide character array WSTRING
+- into a string containing multibyte characters, storing not more
+- than SIZE bytes starting at STRING, followed by a terminating null
+- character if there is room. The conversion of characters begins in
+- the initial shift state.
+-
+- The terminating null character counts towards the size, so if SIZE
+- is less than or equal to the number of bytes needed in WSTRING, no
+- terminating null character is stored.
+-
+- If a code that does not correspond to a valid multibyte character
+- is found, the `wcstombs' function returns a value of -1.
+- Otherwise, the return value is the number of bytes stored in the
+- array STRING. This number does not include the terminating null
+- character, which is present if the number is less than SIZE.

+-
+-States in Non-reentrant Functions
+----------------------------------
+-
+- In some multibyte character codes, the _meaning_ of any particular
+-byte sequence is not fixed; it depends on what other sequences have come
+-earlier in the same string. Typically there are just a few sequences
+-that can change the meaning of other sequences; these few are called
+-"shift sequences" and we say that they set the "shift state" for other
+-sequences that follow.
+-
+- To illustrate shift state and shift sequences, suppose we decide that
+-the sequence `0200' (just one byte) enters Japanese mode, in which
+-pairs of bytes in the range from `0240' to `0377' are single
+-characters, while `0201' enters Latin-1 mode, in which single bytes in
+-the range from `0240' to `0377' are characters, and interpreted
+-according to the ISO Latin-1 character set. This is a multibyte code
+-that has two alternative shift states ("Japanese mode" and "Latin-1
+-mode"), and two shift sequences that specify particular shift states.
+-
+- When the multibyte character code in use has shift states, then
+-`mblen', `mbtowc', and `wctomb' must maintain and update the current
+-shift state as they scan the string. To make this work properly, you
+-must follow these rules:
+-
+- * Before starting to scan a string, call the function with a null
+- pointer for the multibyte character address--for example, `mblen
+- (NULL, 0)'. This initializes the shift state to its standard
+- initial value.
+-
+- * Scan the string one character at a time, in order. Do not "back
+- up" and rescan characters already scanned, and do not intersperse
+- the processing of different strings.
+-
+- Here is an example of using `mblen' following these rules:
+-
+- void
+- scan_string (char *s)
+- {
+- int length = strlen (s);
+-
+- /* Initialize shift state. */
+- mblen (NULL, 0);
+-
+- while (1)
+- {
+- int thischar = mblen (s, length);
+- /* Deal with end of string and invalid characters. */
+- if (thischar == 0)
+- break;
+- if (thischar == -1)
+- {
+- error ("invalid multibyte character");
+- break;
+- }
+- /* Advance past this character. */
+- s += thischar;
+- length -= thischar;
+- }
+- }
+-
+- The functions `mblen', `mbtowc' and `wctomb' are not reentrant when
+-using a multibyte code that uses a shift state. However, no other
+-library functions call these functions, so you don't have to worry that
+-the shift state will be changed mysteriously.

+-Generic Charset Conversion
+-==========================
+-
+- The conversion functions mentioned so far in this chapter all had in
+-common that they operate on character sets that are not directly
+-specified by the functions. The multibyte encoding used is specified by
+-the currently selected locale for the `LC_CTYPE' category. The wide
+-character set is fixed by the implementation (in the case of GNU C
+-library it is always UCS-4 encoded ISO 10646.
+-
+- This has of course several problems when it comes to general
+-character conversion:
+-
+- * For every conversion where neither the source nor the destination
+- character set is the character set of the locale for the `LC_CTYPE'
+- category, one has to change the `LC_CTYPE' locale using
+- `setlocale'.
+-
+- Changing the `LC_TYPE' locale introduces major problems for the
+- rest of the programs since several more functions (e.g., the
+- character classification functions, *note Classification of
+- Characters::) use the `LC_CTYPE' category.
+-
+- * Parallel conversions to and from different character sets are not
+- possible since the `LC_CTYPE' selection is global and shared by all
+- threads.
+-
+- * If neither the source nor the destination character set is the
+- character set used for `wchar_t' representation, there is at least
+- a two-step process necessary to convert a text using the functions
+- above. One would have to select the source character set as the
+- multibyte encoding, convert the text into a `wchar_t' text, select
+- the destination character set as the multibyte encoding, and
+- convert the wide character text to the multibyte (= destination)
+- character set.
+-
+- Even if this is possible (which is not guaranteed) it is a very
+- tiring work. Plus it suffers from the other two raised points
+- even more due to the steady changing of the locale.
+-
+- The XPG2 standard defines a completely new set of functions, which
+-has none of these limitations. They are not at all coupled to the
+-selected locales, and they have no constraints on the character sets
+-selected for source and destination. Only the set of available
+-conversions limits them. The standard does not specify that any
+-conversion at all must be available. Such availability is a measure of
+-the quality of the implementation.
+-
+- In the following text first the interface to `iconv' and then the
+-conversion function, will be described. Comparisons with other
+-implementations will show what obstacles stand in the way of portable
+-applications. Finally, the implementation is described in so far as
+-might interest the advanced user who wants to extend conversion
+-capabilities.

+-Generic Character Set Conversion Interface
+-------------------------------------------
+-
+- This set of functions follows the traditional cycle of using a
+-resource: open-use-close. The interface consists of three functions,
+-each of which implements one step.
+-
+- Before the interfaces are described it is necessary to introduce a
+-data type. Just like other open-use-close interfaces the functions
+-introduced here work using handles and the `iconv.h' header defines a
+-special type for the handles used.
+-
+- - Data Type: iconv_t
+- This data type is an abstract type defined in `iconv.h'. The user
+- must not assume anything about the definition of this type; it
+- must be completely opaque.
+-
+- Objects of this type can get assigned handles for the conversions
+- using the `iconv' functions. The objects themselves need not be
+- freed, but the conversions for which the handles stand for have to.
+-
+-The first step is the function to create a handle.
+-
+- - Function: iconv_t iconv_open (const char *TOCODE, const char
+- *FROMCODE)
+- The `iconv_open' function has to be used before starting a
+- conversion. The two parameters this function takes determine the
+- source and destination character set for the conversion, and if the
+- implementation has the possibility to perform such a conversion,
+- the function returns a handle.
+-
+- If the wanted conversion is not available, the `iconv_open'
+- function returns `(iconv_t) -1'. In this case the global variable
+- `errno' can have the following values:
+-
+- `EMFILE'
+- The process already has `OPEN_MAX' file descriptors open.
+-
+- `ENFILE'
+- The system limit of open file is reached.
+-
+- `ENOMEM'
+- Not enough memory to carry out the operation.
+-
+- `EINVAL'
+- The conversion from FROMCODE to TOCODE is not supported.
+-
+- It is not possible to use the same descriptor in different threads
+- to perform independent conversions. The data structures associated
+- with the descriptor include information about the conversion state.
+- This must not be messed up by using it in different conversions.
+-
+- An `iconv' descriptor is like a file descriptor as for every use a
+- new descriptor must be created. The descriptor does not stand for
+- all of the conversions from FROMSET to TOSET.
+-
+- The GNU C library implementation of `iconv_open' has one
+- significant extension to other implementations. To ease the
+- extension of the set of available conversions, the implementation
+- allows storing the necessary files with data and code in an
+- arbitrary number of directories. How this extension must be
+- written will be explained below (*note glibc iconv
+- Implementation::). Here it is only important to say that all
+- directories mentioned in the `GCONV_PATH' environment variable are
+- considered only if they contain a file `gconv-modules'. These
+- directories need not necessarily be created by the system
+- administrator. In fact, this extension is introduced to help users
+- writing and using their own, new conversions. Of course, this
+- does not work for security reasons in SUID binaries; in this case
+- only the system directory is considered and this normally is
+- `PREFIX/lib/gconv'. The `GCONV_PATH' environment variable is
+- examined exactly once at the first call of the `iconv_open'
+- function. Later modifications of the variable have no effect.
+-
+- The `iconv_open' function was introduced early in the X/Open
+- Portability Guide, version 2. It is supported by all commercial
+- Unices as it is required for the Unix branding. However, the
+- quality and completeness of the implementation varies widely. The
+- `iconv_open' function is declared in `iconv.h'.
+-
+- The `iconv' implementation can associate large data structure with
+-the handle returned by `iconv_open'. Therefore, it is crucial to free
+-all the resources once all conversions are carried out and the
+-conversion is not needed anymore.
+-
+- - Function: int iconv_close (iconv_t CD)
+- The `iconv_close' function frees all resources associated with the
+- handle CD, which must have been returned by a successful call to
+- the `iconv_open' function.
+-
+- If the function call was successful the return value is 0.
+- Otherwise it is -1 and `errno' is set appropriately. Defined
+- error are:
+-
+- `EBADF'
+- The conversion descriptor is invalid.
+-
+- The `iconv_close' function was introduced together with the rest
+- of the `iconv' functions in XPG2 and is declared in `iconv.h'.
+-
+- The standard defines only one actual conversion function. This has,
+-therefore, the most general interface: it allows conversion from one
+-buffer to another. Conversion from a file to a buffer, vice versa, or
+-even file to file can be implemented on top of it.
+-
+- - Function: size_t iconv (iconv_t CD, char **INBUF, size_t
+- *INBYTESLEFT, char **OUTBUF, size_t *OUTBYTESLEFT)
+- The `iconv' function converts the text in the input buffer
+- according to the rules associated with the descriptor CD and
+- stores the result in the output buffer. It is possible to call the
+- function for the same text several times in a row since for
+- stateful character sets the necessary state information is kept in
+- the data structures associated with the descriptor.
+-
+- The input buffer is specified by `*INBUF' and it contains
+- `*INBYTESLEFT' bytes. The extra indirection is necessary for
+- communicating the used input back to the caller (see below). It is
+- important to note that the buffer pointer is of type `char' and the
+- length is measured in bytes even if the input text is encoded in
+- wide characters.
+-
+- The output buffer is specified in a similar way. `*OUTBUF' points
+- to the beginning of the buffer with at least `*OUTBYTESLEFT' bytes
+- room for the result. The buffer pointer again is of type `char'
+- and the length is measured in bytes. If OUTBUF or `*OUTBUF' is a
+- null pointer, the conversion is performed but no output is
+- available.
+-
+- If INBUF is a null pointer, the `iconv' function performs the
+- necessary action to put the state of the conversion into the
+- initial state. This is obviously a no-op for non-stateful
+- encodings, but if the encoding has a state, such a function call
+- might put some byte sequences in the output buffer, which perform
+- the necessary state changes. The next call with INBUF not being a
+- null pointer then simply goes on from the initial state. It is
+- important that the programmer never makes any assumption as to
+- whether the conversion has to deal with states. Even if the input
+- and output character sets are not stateful, the implementation
+- might still have to keep states. This is due to the
+- implementation chosen for the GNU C library as it is described
+- below. Therefore an `iconv' call to reset the state should always
+- be performed if some protocol requires this for the output text.
+-
+- The conversion stops for one of three reasons. The first is that
+- all characters from the input buffer are converted. This actually
+- can mean two things: either all bytes from the input buffer are
+- consumed or there are some bytes at the end of the buffer that
+- possibly can form a complete character but the input is
+- incomplete. The second reason for a stop is that the output
+- buffer is full. And the third reason is that the input contains
+- invalid characters.
+-
+- In all of these cases the buffer pointers after the last successful
+- conversion, for input and output buffer, are stored in INBUF and
+- OUTBUF, and the available room in each buffer is stored in
+- INBYTESLEFT and OUTBYTESLEFT.
+-
+- Since the character sets selected in the `iconv_open' call can be
+- almost arbitrary, there can be situations where the input buffer
+- contains valid characters, which have no identical representation
+- in the output character set. The behavior in this situation is
+- undefined. The _current_ behavior of the GNU C library in this
+- situation is to return with an error immediately. This certainly
+- is not the most desirable solution; therefore, future versions
+- will provide better ones, but they are not yet finished.
+-
+- If all input from the input buffer is successfully converted and
+- stored in the output buffer, the function returns the number of
+- non-reversible conversions performed. In all other cases the
+- return value is `(size_t) -1' and `errno' is set appropriately.
+- In such cases the value pointed to by INBYTESLEFT is nonzero.
+-
+- `EILSEQ'
+- The conversion stopped because of an invalid byte sequence in
+- the input. After the call, `*INBUF' points at the first byte
+- of the invalid byte sequence.
+-
+- `E2BIG'
+- The conversion stopped because it ran out of space in the
+- output buffer.
+-
+- `EINVAL'
+- The conversion stopped because of an incomplete byte sequence
+- at the end of the input buffer.
+-
+- `EBADF'
+- The CD argument is invalid.
+-
+- The `iconv' function was introduced in the XPG2 standard and is
+- declared in the `iconv.h' header.
+-
+- The definition of the `iconv' function is quite good overall. It
+-provides quite flexible functionality. The only problems lie in the
+-boundary cases, which are incomplete byte sequences at the end of the
+-input buffer and invalid input. A third problem, which is not really a
+-design problem, is the way conversions are selected. The standard does
+-not say anything about the legitimate names, a minimal set of available
+-conversions. We will see how this negatively impacts other
+-implementations, as demonstrated below.

+-
+-A complete `iconv' example
+---------------------------
+-
+- The example below features a solution for a common problem. Given
+-that one knows the internal encoding used by the system for `wchar_t'
+-strings, one often is in the position to read text from a file and store
+-it in wide character buffers. One can do this using `mbsrtowcs', but
+-then we run into the problems discussed above.
+-
+- int
+- file2wcs (int fd, const char *charset, wchar_t *outbuf, size_t avail)
+- {
+- char inbuf[BUFSIZ];
+- size_t insize = 0;
+- char *wrptr = (char *) outbuf;
+- int result = 0;
+- iconv_t cd;
+-
+- cd = iconv_open ("WCHAR_T", charset);
+- if (cd == (iconv_t) -1)
+- {
+- /* Something went wrong. */
+- if (errno == EINVAL)
+- error (0, 0, "conversion from '%s' to wchar_t not available",
+- charset);
+- else
+- perror ("iconv_open");
+-
+- /* Terminate the output string. */
+- *outbuf = L'\0';
+-
+- return -1;
+- }
+-
+- while (avail > 0)
+- {
+- size_t nread;
+- size_t nconv;
+- char *inptr = inbuf;
+-
+- /* Read more input. */
+- nread = read (fd, inbuf + insize, sizeof (inbuf) - insize);
+- if (nread == 0)
+- {
+- /* When we come here the file is completely read.
+- This still could mean there are some unused
+- characters in the `inbuf'. Put them back. */
+- if (lseek (fd, -insize, SEEK_CUR) == -1)
+- result = -1;
+-
+- /* Now write out the byte sequence to get into the
+- initial state if this is necessary. */
+- iconv (cd, NULL, NULL, &wrptr, &avail);
+-
+- break;
+- }
+- insize += nread;
+-
+- /* Do the conversion. */
+- nconv = iconv (cd, &inptr, &insize, &wrptr, &avail);
+- if (nconv == (size_t) -1)
+- {
+- /* Not everything went right. It might only be
+- an unfinished byte sequence at the end of the
+- buffer. Or it is a real problem. */
+- if (errno == EINVAL)
+- /* This is harmless. Simply move the unused
+- bytes to the beginning of the buffer so that
+- they can be used in the next round. */
+- memmove (inbuf, inptr, insize);
+- else
+- {
+- /* It is a real problem. Maybe we ran out of
+- space in the output buffer or we have invalid
+- input. In any case back the file pointer to
+- the position of the last processed byte. */
+- lseek (fd, -insize, SEEK_CUR);
+- result = -1;
+- break;
+- }
+- }
+- }
+-
+- /* Terminate the output string. */
+- if (avail >= sizeof (wchar_t))
+- *((wchar_t *) wrptr) = L'\0';
+-
+- if (iconv_close (cd) != 0)
+- perror ("iconv_close");
+-
+- return (wchar_t *) wrptr - outbuf;
+- }
+-
+- This example shows the most important aspects of using the `iconv'
+-functions. It shows how successive calls to `iconv' can be used to
+-convert large amounts of text. The user does not have to care about
+-stateful encodings as the functions take care of everything.
+-
+- An interesting point is the case where `iconv' returns an error and
+-`errno' is set to `EINVAL'. This is not really an error in the
+-transformation. It can happen whenever the input character set contains
+-byte sequences of more than one byte for some character and texts are
+-not processed in one piece. In this case there is a chance that a
+-multibyte sequence is cut. The caller can then simply read the
+-remainder of the takes and feed the offending bytes together with new
+-character from the input to `iconv' and continue the work. The
+-internal state kept in the descriptor is _not_ unspecified after such
+-an event as is the case with the conversion functions from the ISO C
+-standard.
+-
+- The example also shows the problem of using wide character strings
+-with `iconv'. As explained in the description of the `iconv' function
+-above, the function always takes a pointer to a `char' array and the
+-available space is measured in bytes. In the example, the output
+-buffer is a wide character buffer; therefore, we use a local variable
+-WRPTR of type `char *', which is used in the `iconv' calls.
+-
+- This looks rather innocent but can lead to problems on platforms that
+-have tight restriction on alignment. Therefore the caller of `iconv'
+-has to make sure that the pointers passed are suitable for access of
+-characters from the appropriate character set. Since, in the above
+-case, the input parameter to the function is a `wchar_t' pointer, this
+-is the case (unless the user violates alignment when computing the
+-parameter). But in other situations, especially when writing generic
+-functions where one does not know what type of character set one uses
+-and, therefore, treats text as a sequence of bytes, it might become
+-tricky.

+-
+-Some Details about other `iconv' Implementations
+-------------------------------------------------
+-
+- This is not really the place to discuss the `iconv' implementation
+-of other systems but it is necessary to know a bit about them to write
+-portable programs. The above mentioned problems with the specification
+-of the `iconv' functions can lead to portability issues.
+-
+- The first thing to notice is that, due to the large number of
+-character sets in use, it is certainly not practical to encode the
+-conversions directly in the C library. Therefore, the conversion
+-information must come from files outside the C library. This is
+-usually done in one or both of the following ways:
+-
+- * The C library contains a set of generic conversion functions that
+- can read the needed conversion tables and other information from
+- data files. These files get loaded when necessary.
+-
+- This solution is problematic as it requires a great deal of effort
+- to apply to all character sets (potentially an infinite set). The
+- differences in the structure of the different character sets is so
+- large that many different variants of the table-processing
+- functions must be developed. In addition, the generic nature of
+- these functions make them slower than specifically implemented
+- functions.
+-
+- * The C library only contains a framework that can dynamically load
+- object files and execute the conversion functions contained
+- therein.
+-
+- This solution provides much more flexibility. The C library itself
+- contains only very little code and therefore reduces the general
+- memory footprint. Also, with a documented interface between the C
+- library and the loadable modules it is possible for third parties
+- to extend the set of available conversion modules. A drawback of
+- this solution is that dynamic loading must be available.
+-
+- Some implementations in commercial Unices implement a mixture of
+-these possibilities; the majority implement only the second solution.
+-Using loadable modules moves the code out of the library itself and
+-keeps the door open for extensions and improvements, but this design is
+-also limiting on some platforms since not many platforms support dynamic
+-loading in statically linked programs. On platforms without this
+-capability it is therefore not possible to use this interface in
+-statically linked programs. The GNU C library has, on ELF platforms, no
+-problems with dynamic loading in these situations; therefore, this
+-point is moot. The danger is that one gets acquainted with this
+-situation and forgets about the restrictions on other systems.
+-
+- A second thing to know about other `iconv' implementations is that
+-the number of available conversions is often very limited. Some
+-implementations provide, in the standard release (not special
+-international or developer releases), at most 100 to 200 conversion
+-possibilities. This does not mean 200 different character sets are
+-supported; for example, conversions from one character set to a set of
+-10 others might count as 10 conversions. Together with the other
+-direction this makes 20 conversion possibilities used up by one
+-character set. One can imagine the thin coverage these platform
+-provide. Some Unix vendors even provide only a handful of conversions,
+-which renders them useless for almost all uses.
+-
+- This directly leads to a third and probably the most problematic
+-point. The way the `iconv' conversion functions are implemented on all
+-known Unix systems and the availability of the conversion functions from
+-character set A to B and the conversion from B to C does _not_ imply
+-that the conversion from A to C is available.
+-
+- This might not seem unreasonable and problematic at first, but it is
+-a quite big problem as one will notice shortly after hitting it. To
+-show the problem we assume to write a program that has to convert from
+-A to C. A call like
+-
+- cd = iconv_open ("C", "A");
+-
+-fails according to the assumption above. But what does the program do
+-now? The conversion is necessary; therefore, simply giving up is not
+-an option.
+-
+- This is a nuisance. The `iconv' function should take care of this.
+-But how should the program proceed from here on? If it tries to convert
+-to character set B, first the two `iconv_open' calls
+-
+- cd1 = iconv_open ("B", "A");
+-
+-and
+-
+- cd2 = iconv_open ("C", "B");
+-
+-will succeed, but how to find B?
+-
+- Unfortunately, the answer is: there is no general solution. On some
+-systems guessing might help. On those systems most character sets can
+-convert to and from UTF-8 encoded ISO 10646 or Unicode text. Beside
+-this only some very system-specific methods can help. Since the
+-conversion functions come from loadable modules and these modules must
+-be stored somewhere in the filesystem, one _could_ try to find them and
+-determine from the available file which conversions are available and
+-whether there is an indirect route from A to C.
+-
+- This example shows one of the design errors of `iconv' mentioned
+-above. It should at least be possible to determine the list of
+-available conversion programmatically so that if `iconv_open' says
+-there is no such conversion, one could make sure this also is true for
+-indirect routes.

+-
+-The `iconv' Implementation in the GNU C library
+------------------------------------------------
+-
+- After reading about the problems of `iconv' implementations in the
+-last section it is certainly good to note that the implementation in
+-the GNU C library has none of the problems mentioned above. What
+-follows is a step-by-step analysis of the points raised above. The
+-evaluation is based on the current state of the development (as of
+-January 1999). The development of the `iconv' functions is not
+-complete, but basic functionality has solidified.
+-
+- The GNU C library's `iconv' implementation uses shared loadable
+-modules to implement the conversions. A very small number of
+-conversions are built into the library itself but these are only rather
+-trivial conversions.
+-
+- All the benefits of loadable modules are available in the GNU C
+-library implementation. This is especially appealing since the
+-interface is well documented (see below), and it, therefore, is easy to
+-write new conversion modules. The drawback of using loadable objects
+-is not a problem in the GNU C library, at least on ELF systems. Since
+-the library is able to load shared objects even in statically linked
+-binaries, static linking need not be forbidden in case one wants to use
+-`iconv'.
+-
+- The second mentioned problem is the number of supported conversions.
+-Currently, the GNU C library supports more than 150 character sets. The
+-way the implementation is designed the number of supported conversions
+-is greater than 22350 (150 times 149). If any conversion from or to a
+-character set is missing, it can be added easily.
+-
+- Particularly impressive as it may be, this high number is due to the
+-fact that the GNU C library implementation of `iconv' does not have the
+-third problem mentioned above (i.e., whenever there is a conversion
+-from a character set A to B and from B to C it is always possible to
+-convert from A to C directly). If the `iconv_open' returns an error
+-and sets `errno' to `EINVAL', there is no known way, directly or
+-indirectly, to perform the wanted conversion.
+-
+- Triangulation is achieved by providing for each character set a
+-conversion from and to UCS-4 encoded ISO 10646. Using ISO 10646 as an
+-intermediate representation it is possible to "triangulate" (i.e.,
+-convert with an intermediate representation).
+-
+- There is no inherent requirement to provide a conversion to
+-ISO 10646 for a new character set, and it is also possible to provide
+-other conversions where neither source nor destination character set is
+-ISO 10646. The existing set of conversions is simply meant to cover all
+-conversions that might be of interest.
+-
+- All currently available conversions use the triangulation method
+-above, making conversion run unnecessarily slow. If, for example,
+-somebody often needs the conversion from ISO-2022-JP to EUC-JP, a
+-quicker solution would involve direct conversion between the two
+-character sets, skipping the input to ISO 10646 first. The two
+-character sets of interest are much more similar to each other than to
+-ISO 10646.
+-
+- In such a situation one easily can write a new conversion and
+-provide it as a better alternative. The GNU C library `iconv'
+-implementation would automatically use the module implementing the
+-conversion if it is specified to be more efficient.
+-
+-Format of `gconv-modules' files
+-...............................
+-
+- All information about the available conversions comes from a file
+-named `gconv-modules', which can be found in any of the directories
+-along the `GCONV_PATH'. The `gconv-modules' files are line-oriented
+-text files, where each of the lines has one of the following formats:
+-
+- * If the first non-whitespace character is a `#' the line contains
+- only comments and is ignored.
+-
+- * Lines starting with `alias' define an alias name for a character
+- set. Two more words are expected on the line. The first word
+- defines the alias name, and the second defines the original name
+- of the character set. The effect is that it is possible to use
+- the alias name in the FROMSET or TOSET parameters of `iconv_open'
+- and achieve the same result as when using the real character set
+- name.
+-
+- This is quite important as a character set has often many different
+- names. There is normally an official name but this need not
+- correspond to the most popular name. Beside this many character
+- sets have special names that are somehow constructed. For
+- example, all character sets specified by the ISO have an alias of
+- the form `ISO-IR-NNN' where NNN is the registration number. This
+- allows programs that know about the registration number to
+- construct character set names and use them in `iconv_open' calls.
+- More on the available names and aliases follows below.
+-
+- * Lines starting with `module' introduce an available conversion
+- module. These lines must contain three or four more words.
+-
+- The first word specifies the source character set, the second word
+- the destination character set of conversion implemented in this
+- module, and the third word is the name of the loadable module.
+- The filename is constructed by appending the usual shared object
+- suffix (normally `.so') and this file is then supposed to be found
+- in the same directory the `gconv-modules' file is in. The last
+- word on the line, which is optional, is a numeric value
+- representing the cost of the conversion. If this word is missing,
+- a cost of 1 is assumed. The numeric value itself does not matter
+- that much; what counts are the relative values of the sums of
+- costs for all possible conversion paths. Below is a more precise
+- description of the use of the cost value.
+-
+- Returning to the example above where one has written a module to
+-directly convert from ISO-2022-JP to EUC-JP and back. All that has to
+-be done is to put the new module, let its name be ISO2022JP-EUCJP.so,
+-in a directory and add a file `gconv-modules' with the following
+-content in the same directory:
+-
+- module ISO-2022-JP// EUC-JP// ISO2022JP-EUCJP 1
+- module EUC-JP// ISO-2022-JP// ISO2022JP-EUCJP 1
+-
+- To see why this is sufficient, it is necessary to understand how the
+-conversion used by `iconv' (and described in the descriptor) is
+-selected. The approach to this problem is quite simple.
+-
+- At the first call of the `iconv_open' function the program reads all
+-available `gconv-modules' files and builds up two tables: one
+-containing all the known aliases and another that contains the
+-information about the conversions and which shared object implements
+-them.
+-
+-Finding the conversion path in `iconv'
+-......................................
+-
+- The set of available conversions form a directed graph with weighted
+-edges. The weights on the edges are the costs specified in the
+-`gconv-modules' files. The `iconv_open' function uses an algorithm
+-suitable for search for the best path in such a graph and so constructs
+-a list of conversions that must be performed in succession to get the
+-transformation from the source to the destination character set.
+-
+- Explaining why the above `gconv-modules' files allows the `iconv'
+-implementation to resolve the specific ISO-2022-JP to EUC-JP conversion
+-module instead of the conversion coming with the library itself is
+-straightforward. Since the latter conversion takes two steps (from
+-ISO-2022-JP to ISO 10646 and then from ISO 10646 to EUC-JP), the cost
+-is 1+1 = 2. The above `gconv-modules' file, however, specifies that
+-the new conversion modules can perform this conversion with only the
+-cost of 1.
+-
+- A mysterious item about the `gconv-modules' file above (and also the
+-file coming with the GNU C library) are the names of the character sets
+-specified in the `module' lines. Why do almost all the names end in
+-`//'? And this is not all: the names can actually be regular
+-expressions. At this point in time this mystery should not be
+-revealed, unless you have the relevant spell-casting materials: ashes
+-from an original DOS 6.2 boot disk burnt in effigy, a crucifix blessed
+-by St. Emacs, assorted herbal roots from Central America, sand from
+-Cebu, etc. Sorry! *The part of the implementation where this is used
+-is not yet finished. For now please simply follow the existing
+-examples. It'll become clearer once it is. -drepper*
+-
+- A last remark about the `gconv-modules' is about the names not
+-ending with `//'. A character set named `INTERNAL' is often mentioned.
+-From the discussion above and the chosen name it should have become
+-clear that this is the name for the representation used in the
+-intermediate step of the triangulation. We have said that this is UCS-4
+-but actually that is not quite right. The UCS-4 specification also
+-includes the specification of the byte ordering used. Since a UCS-4
+-value consists of four bytes, a stored value is effected by byte
+-ordering. The internal representation is _not_ the same as UCS-4 in
+-case the byte ordering of the processor (or at least the running
+-process) is not the same as the one required for UCS-4. This is done
+-for performance reasons as one does not want to perform unnecessary
+-byte-swapping operations if one is not interested in actually seeing
+-the result in UCS-4. To avoid trouble with endianess, the internal
+-representation consistently is named `INTERNAL' even on big-endian
+-systems where the representations are identical.
+-
+-`iconv' module data structures
+-..............................
+-
+- So far this section has described how modules are located and
+-considered to be used. What remains to be described is the interface
+-of the modules so that one can write new ones. This section describes
+-the interface as it is in use in January 1999. The interface will
+-change a bit in the future but, with luck, only in an upwardly
+-compatible way.
+-
+- The definitions necessary to write new modules are publicly available
+-in the non-standard header `gconv.h'. The following text, therefore,
+-describes the definitions from this header file. First, however, it is
+-necessary to get an overview.
+-
+- From the perspective of the user of `iconv' the interface is quite
+-simple: the `iconv_open' function returns a handle that can be used in
+-calls to `iconv', and finally the handle is freed with a call to
+-`iconv_close'. The problem is that the handle has to be able to
+-represent the possibly long sequences of conversion steps and also the
+-state of each conversion since the handle is all that is passed to the
+-`iconv' function. Therefore, the data structures are really the
+-elements necessary to understanding the implementation.
+-
+- We need two different kinds of data structures. The first describes
+-the conversion and the second describes the state etc. There are
+-really two type definitions like this in `gconv.h'.
+-
+- - Data type: struct __gconv_step
+- This data structure describes one conversion a module can perform.
+- For each function in a loaded module with conversion functions
+- there is exactly one object of this type. This object is shared
+- by all users of the conversion (i.e., this object does not contain
+- any information corresponding to an actual conversion; it only
+- describes the conversion itself).
+-
+- `struct __gconv_loaded_object *__shlib_handle'
+- `const char *__modname'
+- `int __counter'
+- All these elements of the structure are used internally in
+- the C library to coordinate loading and unloading the shared.
+- One must not expect any of the other elements to be
+- available or initialized.
+-
+- `const char *__from_name'
+- `const char *__to_name'
+- `__from_name' and `__to_name' contain the names of the source
+- and destination character sets. They can be used to identify
+- the actual conversion to be carried out since one module
+- might implement conversions for more than one character set
+- and/or direction.
+-
+- `gconv_fct __fct'
+- `gconv_init_fct __init_fct'
+- `gconv_end_fct __end_fct'
+- These elements contain pointers to the functions in the
+- loadable module. The interface will be explained below.
+-
+- `int __min_needed_from'
+- `int __max_needed_from'
+- `int __min_needed_to'
+- `int __max_needed_to;'
+- These values have to be supplied in the init function of the
+- module. The `__min_needed_from' value specifies how many
+- bytes a character of the source character set at least needs.
+- The `__max_needed_from' specifies the maximum value that
+- also includes possible shift sequences.
+-
+- The `__min_needed_to' and `__max_needed_to' values serve the
+- same purpose as `__min_needed_from' and `__max_needed_from'
+- but this time for the destination character set.
+-
+- It is crucial that these values be accurate since otherwise
+- the conversion functions will have problems or not work at
+- all.
+-
+- `int __stateful'
+- This element must also be initialized by the init function.
+- `int __stateful' is nonzero if the source character set is
+- stateful. Otherwise it is zero.
+-
+- `void *__data'
+- This element can be used freely by the conversion functions
+- in the module. `void *__data' can be used to communicate
+- extra information from one call to another. `void *__data'
+- need not be initialized if not needed at all. If `void
+- *__data' element is assigned a pointer to dynamically
+- allocated memory (presumably in the init function) it has to
+- be made sure that the end function deallocates the memory.
+- Otherwise the application will leak memory.
+-
+- It is important to be aware that this data structure is
+- shared by all users of this specification conversion and
+- therefore the `__data' element must not contain data specific
+- to one specific use of the conversion function.
+-
+- - Data type: struct __gconv_step_data
+- This is the data structure that contains the information specific
+- to each use of the conversion functions.
+-
+- `char *__outbuf'
+- `char *__outbufend'
+- These elements specify the output buffer for the conversion
+- step. The `__outbuf' element points to the beginning of the
+- buffer, and `__outbufend' points to the byte following the
+- last byte in the buffer. The conversion function must not
+- assume anything about the size of the buffer but it can be
+- safely assumed the there is room for at least one complete
+- character in the output buffer.
+-
+- Once the conversion is finished, if the conversion is the
+- last step, the `__outbuf' element must be modified to point
+- after the last byte written into the buffer to signal how
+- much output is available. If this conversion step is not the
+- last one, the element must not be modified. The
+- `__outbufend' element must not be modified.
+-
+- `int __is_last'
+- This element is nonzero if this conversion step is the last
+- one. This information is necessary for the recursion. See
+- the description of the conversion function internals below.
+- This element must never be modified.
+-
+- `int __invocation_counter'
+- The conversion function can use this element to see how many
+- calls of the conversion function already happened. Some
+- character sets require a certain prolog when generating
+- output, and by comparing this value with zero, one can find
+- out whether it is the first call and whether, therefore, the
+- prolog should be emitted. This element must never be
+- modified.
+-
+- `int __internal_use'
+- This element is another one rarely used but needed in certain
+- situations. It is assigned a nonzero value in case the
+- conversion functions are used to implement `mbsrtowcs' et.al.
+- (i.e., the function is not used directly through the `iconv'
+- interface).
+-
+- This sometimes makes a difference as it is expected that the
+- `iconv' functions are used to translate entire texts while the
+- `mbsrtowcs' functions are normally used only to convert single
+- strings and might be used multiple times to convert entire
+- texts.
+-
+- But in this situation we would have problem complying with
+- some rules of the character set specification. Some
+- character sets require a prolog, which must appear exactly
+- once for an entire text. If a number of `mbsrtowcs' calls
+- are used to convert the text, only the first call must add
+- the prolog. However, because there is no communication
+- between the different calls of `mbsrtowcs', the conversion
+- functions have no possibility to find this out. The
+- situation is different for sequences of `iconv' calls since
+- the handle allows access to the needed information.
+-
+- The `int __internal_use' element is mostly used together with
+- `__invocation_counter' as follows:
+-
+- if (!data->__internal_use
+- && data->__invocation_counter == 0)
+- /* Emit prolog. */
+- ...
+-
+- This element must never be modified.
+-
+- `mbstate_t *__statep'
+- The `__statep' element points to an object of type `mbstate_t'
+- (*note Keeping the state::). The conversion of a stateful
+- character set must use the object pointed to by `__statep' to
+- store information about the conversion state. The `__statep'
+- element itself must never be modified.
+-
+- `mbstate_t __state'
+- This element must _never_ be used directly. It is only part
+- of this structure to have the needed space allocated.
+-
+-`iconv' module interfaces
+-.........................
+-
+- With the knowledge about the data structures we now can describe the
+-conversion function itself. To understand the interface a bit of
+-knowledge is necessary about the functionality in the C library that
+-loads the objects with the conversions.
+-
+- It is often the case that one conversion is used more than once
+-(i.e., there are several `iconv_open' calls for the same set of
+-character sets during one program run). The `mbsrtowcs' et.al.
+-functions in the GNU C library also use the `iconv' functionality, which
+-increases the number of uses of the same functions even more.
+-
+- Because of this multiple use of conversions, the modules do not get
+-loaded exclusively for one conversion. Instead a module once loaded can
+-be used by an arbitrary number of `iconv' or `mbsrtowcs' calls at the
+-same time. The splitting of the information between conversion-
+-function-specific information and conversion data makes this possible.
+-The last section showed the two data structures used to do this.
+-
+- This is of course also reflected in the interface and semantics of
+-the functions that the modules must provide. There are three functions
+-that must have the following names:
+-
+-`gconv_init'
+- The `gconv_init' function initializes the conversion function
+- specific data structure. This very same object is shared by all
+- conversions that use this conversion and, therefore, no state
+- information about the conversion itself must be stored in here.
+- If a module implements more than one conversion, the `gconv_init'
+- function will be called multiple times.
+-
+-`gconv_end'
+- The `gconv_end' function is responsible for freeing all resources
+- allocated by the `gconv_init' function. If there is nothing to do,
+- this function can be missing. Special care must be taken if the
+- module implements more than one conversion and the `gconv_init'
+- function does not allocate the same resources for all conversions.
+-
+-`gconv'
+- This is the actual conversion function. It is called to convert
+- one block of text. It gets passed the conversion step information
+- initialized by `gconv_init' and the conversion data, specific to
+- this use of the conversion functions.
+-
+- There are three data types defined for the three module interface
+-functions and these define the interface.
+-
+- - Data type: int (*__gconv_init_fct) (struct __gconv_step *)
+- This specifies the interface of the initialization function of the
+- module. It is called exactly once for each conversion the module
+- implements.
+-
+- As explained in the description of the `struct __gconv_step' data
+- structure above the initialization function has to initialize
+- parts of it.
+-
+- `__min_needed_from'
+- `__max_needed_from'
+- `__min_needed_to'
+- `__max_needed_to'
+- These elements must be initialized to the exact numbers of
+- the minimum and maximum number of bytes used by one character
+- in the source and destination character sets, respectively.
+- If the characters all have the same size, the minimum and
+- maximum values are the same.
+-
+- `__stateful'
+- This element must be initialized to an nonzero value if the
+- source character set is stateful. Otherwise it must be zero.
+-
+- If the initialization function needs to communicate some
+- information to the conversion function, this communication can
+- happen using the `__data' element of the `__gconv_step' structure.
+- But since this data is shared by all the conversions, it must not
+- be modified by the conversion function. The example below shows
+- how this can be used.
+-
+- #define MIN_NEEDED_FROM 1
+- #define MAX_NEEDED_FROM 4
+- #define MIN_NEEDED_TO 4
+- #define MAX_NEEDED_TO 4
+-
+- int
+- gconv_init (struct __gconv_step *step)
+- {
+- /* Determine which direction. */
+- struct iso2022jp_data *new_data;
+- enum direction dir = illegal_dir;
+- enum variant var = illegal_var;
+- int result;
+-
+- if (__strcasecmp (step->__from_name, "ISO-2022-JP//") == 0)
+- {
+- dir = from_iso2022jp;
+- var = iso2022jp;
+- }
+- else if (__strcasecmp (step->__to_name, "ISO-2022-JP//") == 0)
+- {
+- dir = to_iso2022jp;
+- var = iso2022jp;
+- }
+- else if (__strcasecmp (step->__from_name, "ISO-2022-JP-2//") == 0)
+- {
+- dir = from_iso2022jp;
+- var = iso2022jp2;
+- }
+- else if (__strcasecmp (step->__to_name, "ISO-2022-JP-2//") == 0)
+- {
+- dir = to_iso2022jp;
+- var = iso2022jp2;
+- }
+-
+- result = __GCONV_NOCONV;
+- if (dir != illegal_dir)
+- {
+- new_data = (struct iso2022jp_data *)
+- malloc (sizeof (struct iso2022jp_data));
+-
+- result = __GCONV_NOMEM;
+- if (new_data != NULL)
+- {
+- new_data->dir = dir;
+- new_data->var = var;
+- step->__data = new_data;
+-
+- if (dir == from_iso2022jp)
+- {
+- step->__min_needed_from = MIN_NEEDED_FROM;
+- step->__max_needed_from = MAX_NEEDED_FROM;
+- step->__min_needed_to = MIN_NEEDED_TO;
+- step->__max_needed_to = MAX_NEEDED_TO;
+- }
+- else
+- {
+- step->__min_needed_from = MIN_NEEDED_TO;
+- step->__max_needed_from = MAX_NEEDED_TO;
+- step->__min_needed_to = MIN_NEEDED_FROM;
+- step->__max_needed_to = MAX_NEEDED_FROM + 2;
+- }
+-
+- /* Yes, this is a stateful encoding. */
+- step->__stateful = 1;
+-
+- result = __GCONV_OK;
+- }
+- }
+-
+- return result;
+- }
+-
+- The function first checks which conversion is wanted. The module
+- from which this function is taken implements four different
+- conversions; which one is selected can be determined by comparing
+- the names. The comparison should always be done without paying
+- attention to the case.
+-
+- Next, a data structure, which contains the necessary information
+- about which conversion is selected, is allocated. The data
+- structure `struct iso2022jp_data' is locally defined since,
+- outside the module, this data is not used at all. Please note
+- that if all four conversions this modules supports are requested
+- there are four data blocks.
+-
+- One interesting thing is the initialization of the `__min_' and
+- `__max_' elements of the step data object. A single ISO-2022-JP
+- character can consist of one to four bytes. Therefore the
+- `MIN_NEEDED_FROM' and `MAX_NEEDED_FROM' macros are defined this
+- way. The output is always the `INTERNAL' character set (aka
+- UCS-4) and therefore each character consists of exactly four
+- bytes. For the conversion from `INTERNAL' to ISO-2022-JP we have
+- to take into account that escape sequences might be necessary to
+- switch the character sets. Therefore the `__max_needed_to'
+- element for this direction gets assigned `MAX_NEEDED_FROM + 2'.
+- This takes into account the two bytes needed for the escape
+- sequences to single the switching. The asymmetry in the maximum
+- values for the two directions can be explained easily: when
+- reading ISO-2022-JP text, escape sequences can be handled alone
+- (i.e., it is not necessary to process a real character since the
+- effect of the escape sequence can be recorded in the state
+- information). The situation is different for the other direction.
+- Since it is in general not known which character comes next, one
+- cannot emit escape sequences to change the state in advance. This
+- means the escape sequences that have to be emitted together with
+- the next character. Therefore one needs more room than only for
+- the character itself.
+-
+- The possible return values of the initialization function are:
+-
+- `__GCONV_OK'
+- The initialization succeeded
+-
+- `__GCONV_NOCONV'
+- The requested conversion is not supported in the module.
+- This can happen if the `gconv-modules' file has errors.
+-
+- `__GCONV_NOMEM'
+- Memory required to store additional information could not be
+- allocated.
+-
+- The function called before the module is unloaded is significantly
+-easier. It often has nothing at all to do; in which case it can be left
+-out completely.
+-
+- - Data type: void (*__gconv_end_fct) (struct gconv_step *)
+- The task of this function is to free all resources allocated in the
+- initialization function. Therefore only the `__data' element of
+- the object pointed to by the argument is of interest. Continuing
+- the example from the initialization function, the finalization
+- function looks like this:
+-
+- void
+- gconv_end (struct __gconv_step *data)
+- {
+- free (data->__data);
+- }
+-
+- The most important function is the conversion function itself, which
+-can get quite complicated for complex character sets. But since this
+-is not of interest here, we will only describe a possible skeleton for
+-the conversion function.
+-
+- - Data type: int (*__gconv_fct) (struct __gconv_step *, struct
+- __gconv_step_data *, const char **, const char *, size_t *,
+- int)
+- The conversion function can be called for two basic reason: to
+- convert text or to reset the state. From the description of the
+- `iconv' function it can be seen why the flushing mode is
+- necessary. What mode is selected is determined by the sixth
+- argument, an integer. This argument being nonzero means that
+- flushing is selected.
+-
+- Common to both modes is where the output buffer can be found. The
+- information about this buffer is stored in the conversion step
+- data. A pointer to this information is passed as the second
+- argument to this function. The description of the `struct
+- __gconv_step_data' structure has more information on the
+- conversion step data.
+-
+- What has to be done for flushing depends on the source character
+- set. If the source character set is not stateful, nothing has to
+- be done. Otherwise the function has to emit a byte sequence to
+- bring the state object into the initial state. Once this all
+- happened the other conversion modules in the chain of conversions
+- have to get the same chance. Whether another step follows can be
+- determined from the `__is_last' element of the step data structure
+- to which the first parameter points.
+-
+- The more interesting mode is when actual text has to be converted.
+- The first step in this case is to convert as much text as
+- possible from the input buffer and store the result in the output
+- buffer. The start of the input buffer is determined by the third
+- argument, which is a pointer to a pointer variable referencing the
+- beginning of the buffer. The fourth argument is a pointer to the
+- byte right after the last byte in the buffer.
+-
+- The conversion has to be performed according to the current state
+- if the character set is stateful. The state is stored in an
+- object pointed to by the `__statep' element of the step data
+- (second argument). Once either the input buffer is empty or the
+- output buffer is full the conversion stops. At this point, the
+- pointer variable referenced by the third parameter must point to
+- the byte following the last processed byte (i.e., if all of the
+- input is consumed, this pointer and the fourth parameter have the
+- same value).
+-
+- What now happens depends on whether this step is the last one. If
+- it is the last step, the only thing that has to be done is to
+- update the `__outbuf' element of the step data structure to point
+- after the last written byte. This update gives the caller the
+- information on how much text is available in the output buffer.
+- In addition, the variable pointed to by the fifth parameter, which
+- is of type `size_t', must be incremented by the number of
+- characters (_not bytes_) that were converted in a non-reversible
+- way. Then, the function can return.
+-
+- In case the step is not the last one, the later conversion
+- functions have to get a chance to do their work. Therefore, the
+- appropriate conversion function has to be called. The information
+- about the functions is stored in the conversion data structures,
+- passed as the first parameter. This information and the step data
+- are stored in arrays, so the next element in both cases can be
+- found by simple pointer arithmetic:
+-
+- int
+- gconv (struct __gconv_step *step, struct __gconv_step_data *data,
+- const char **inbuf, const char *inbufend, size_t *written,
+- int do_flush)
+- {
+- struct __gconv_step *next_step = step + 1;
+- struct __gconv_step_data *next_data = data + 1;
+- ...
+-
+- The `next_step' pointer references the next step information and
+- `next_data' the next data record. The call of the next function
+- therefore will look similar to this:
+-
+- next_step->__fct (next_step, next_data, &outerr, outbuf,
+- written, 0)
+-
+- But this is not yet all. Once the function call returns the
+- conversion function might have some more to do. If the return
+- value of the function is `__GCONV_EMPTY_INPUT', more room is
+- available in the output buffer. Unless the input buffer is empty
+- the conversion, functions start all over again and process the
+- rest of the input buffer. If the return value is not
+- `__GCONV_EMPTY_INPUT', something went wrong and we have to recover
+- from this.
+-
+- A requirement for the conversion function is that the input buffer
+- pointer (the third argument) always point to the last character
+- that was put in converted form into the output buffer. This is
+- trivially true after the conversion performed in the current step,
+- but if the conversion functions deeper downstream stop
+- prematurely, not all characters from the output buffer are
+- consumed and, therefore, the input buffer pointers must be backed
+- off to the right position.
+-
+- Correcting the input buffers is easy to do if the input and output
+- character sets have a fixed width for all characters. In this
+- situation we can compute how many characters are left in the
+- output buffer and, therefore, can correct the input buffer pointer
+- appropriately with a similar computation. Things are getting
+- tricky if either character set has characters represented with
+- variable length byte sequences, and it gets even more complicated
+- if the conversion has to take care of the state. In these cases
+- the conversion has to be performed once again, from the known
+- state before the initial conversion (i.e., if necessary the state
+- of the conversion has to be reset and the conversion loop has to be
+- executed again). The difference now is that it is known how much
+- input must be created, and the conversion can stop before
+- converting the first unused character. Once this is done the
+- input buffer pointers must be updated again and the function can
+- return.
+-
+- One final thing should be mentioned. If it is necessary for the
+- conversion to know whether it is the first invocation (in case a
+- prolog has to be emitted), the conversion function should
+- increment the `__invocation_counter' element of the step data
+- structure just before returning to the caller. See the
+- description of the `struct __gconv_step_data' structure above for
+- more information on how this can be used.
+-
+- The return value must be one of the following values:
+-
+- `__GCONV_EMPTY_INPUT'
+- All input was consumed and there is room left in the output
+- buffer.
+-
+- `__GCONV_FULL_OUTPUT'
+- No more room in the output buffer. In case this is not the
+- last step this value is propagated down from the call of the
+- next conversion function in the chain.
+-
+- `__GCONV_INCOMPLETE_INPUT'
+- The input buffer is not entirely empty since it contains an
+- incomplete character sequence.
+-
+- The following example provides a framework for a conversion
+- function. In case a new conversion has to be written the holes in
+- this implementation have to be filled and that is it.
+-
+- int
+- gconv (struct __gconv_step *step, struct __gconv_step_data *data,
+- const char **inbuf, const char *inbufend, size_t *written,

+- }
+- while (status == __GCONV_OK);
+-
+- /* We finished one use of this step. */
+- ++data->__invocation_counter;
+- }
+-
+- return status;
+- }
+-
+- This information should be sufficient to write new modules. Anybody
+-doing so should also take a look at the available source code in the GNU
+-C library sources. It contains many examples of working and optimized
+-modules.

+-

+-
+-What Effects a Locale Has
+-=========================
+-
+- Each locale specifies conventions for several purposes, including the
+-following:
+-
+- * What multibyte character sequences are valid, and how they are
+- interpreted (*note Character Set Handling::).
+-
+- * Classification of which characters in the local character set are
+- considered alphabetic, and upper- and lower-case conversion
+- conventions (*note Character Handling::).
+-
+- * The collating sequence for the local language and character set
+- (*note Collation Functions::).
+-
+- * Formatting of numbers and currency amounts (*note General
+- Numeric::).
+-
+- * Formatting of dates and times (*note Formatting Calendar Time::).
+-
+- * What language to use for output, including error messages (*note
+- Message Translation::).
+-
+- * What language to use for user answers to yes-or-no questions
+- (*note Yes-or-No Questions::).
+-
+- * What language to use for more complex user input. (The C library
+- doesn't yet help you implement this.)
+-
+- Some aspects of adapting to the specified locale are handled
+-automatically by the library subroutines. For example, all your program
+-needs to do in order to use the collating sequence of the chosen locale
+-is to use `strcoll' or `strxfrm' to compare strings.
+-
+- Other aspects of locales are beyond the comprehension of the library.
+-For example, the library can't automatically translate your program's
+-output messages into other languages. The only way you can support
+-output in the user's favorite language is to program this more or less
+-by hand. The C library provides functions to handle translations for
+-multiple languages easily.
+-
+- This chapter discusses the mechanism by which you can modify the
+-current locale. The effects of the current locale on specific library
+-functions are discussed in more detail in the descriptions of those
+-functions.

+-
+-Choosing a Locale
+-=================
+-
+- The simplest way for the user to choose a locale is to set the
+-environment variable `LANG'. This specifies a single locale to use for
+-all purposes. For example, a user could specify a hypothetical locale
+-named `espana-castellano' to use the standard conventions of most of
+-Spain.
+-
+- The set of locales supported depends on the operating system you are
+-using, and so do their names. We can't make any promises about what
+-locales will exist, except for one standard locale called `C' or
+-`POSIX'. Later we will describe how to construct locales.
+-
+- A user also has the option of specifying different locales for
+-different purposes--in effect, choosing a mixture of multiple locales.
+-
+- For example, the user might specify the locale `espana-castellano'
+-for most purposes, but specify the locale `usa-english' for currency
+-formatting. This might make sense if the user is a Spanish-speaking
+-American, working in Spanish, but representing monetary amounts in US
+-dollars.
+-
+- Note that both locales `espana-castellano' and `usa-english', like
+-all locales, would include conventions for all of the purposes to which
+-locales apply. However, the user can choose to use each locale for a
+-particular subset of those purposes.

+-
+-Categories of Activities that Locales Affect
+-============================================
+-
+- The purposes that locales serve are grouped into "categories", so
+-that a user or a program can choose the locale for each category
+-independently. Here is a table of categories; each name is both an
+-environment variable that a user can set, and a macro name that you can
+-use as an argument to `setlocale'.
+-
+-`LC_COLLATE'
+- This category applies to collation of strings (functions `strcoll'
+- and `strxfrm'); see *Note Collation Functions::.
+-
+-`LC_CTYPE'
+- This category applies to classification and conversion of
+- characters, and to multibyte and wide characters; see *Note
+- Character Handling::, and *Note Character Set Handling::.
+-
+-`LC_MONETARY'
+- This category applies to formatting monetary values; see *Note
+- General Numeric::.
+-
+-`LC_NUMERIC'
+- This category applies to formatting numeric values that are not
+- monetary; see *Note General Numeric::.
+-
+-`LC_TIME'
+- This category applies to formatting date and time values; see
+- *Note Formatting Calendar Time::.
+-
+-`LC_MESSAGES'
+- This category applies to selecting the language used in the user
+- interface for message translation (*note The Uniforum approach::;
+- *note Message catalogs a la X/Open::) and contains regular
+- expressions for affirmative and negative responses.
+-
+-`LC_ALL'
+- This is not an environment variable; it is only a macro that you
+- can use with `setlocale' to set a single locale for all purposes.
+- Setting this environment variable overwrites all selections by the
+- other `LC_*' variables or `LANG'.
+-
+-`LANG'
+- If this environment variable is defined, its value specifies the
+- locale to use for all purposes except as overridden by the
+- variables above.
+-
+- When developing the message translation functions it was felt that
+-the functionality provided by the variables above is not sufficient.
+-For example, it should be possible to specify more than one locale name.
+-Take a Swedish user who better speaks German than English, and a program
+-whose messages are output in English by default. It should be possible
+-to specify that the first choice of language is Swedish, the second
+-German, and if this also fails to use English. This is possible with
+-the variable `LANGUAGE'. For further description of this GNU extension
+-see *Note Using gettextized software::.

+-
+-How Programs Set the Locale
+-===========================
+-
+- A C program inherits its locale environment variables when it starts
+-up. This happens automatically. However, these variables do not
+-automatically control the locale used by the library functions, because
+-ISO C says that all programs start by default in the standard `C'
+-locale. To use the locales specified by the environment, you must call
+-`setlocale'. Call it as follows:
+-
+- setlocale (LC_ALL, "");
+-
+-to select a locale based on the user choice of the appropriate
+-environment variables.
+-
+- You can also use `setlocale' to specify a particular locale, for
+-general use or for a specific category.
+-
+- The symbols in this section are defined in the header file
+-`locale.h'.
+-
+- - Function: char * setlocale (int CATEGORY, const char *LOCALE)
+- The function `setlocale' sets the current locale for category
+- CATEGORY to LOCALE. A list of all the locales the system provides
+- can be created by running
+-
+- locale -a
+-
+- If CATEGORY is `LC_ALL', this specifies the locale for all
+- purposes. The other possible values of CATEGORY specify an single
+- purpose (*note Locale Categories::).
+-
+- You can also use this function to find out the current locale by
+- passing a null pointer as the LOCALE argument. In this case,
+- `setlocale' returns a string that is the name of the locale
+- currently selected for category CATEGORY.
+-
+- The string returned by `setlocale' can be overwritten by subsequent
+- calls, so you should make a copy of the string (*note Copying and
+- Concatenation::) if you want to save it past any further calls to
+- `setlocale'. (The standard library is guaranteed never to call
+- `setlocale' itself.)
+-
+- You should not modify the string returned by `setlocale'. It might
+- be the same string that was passed as an argument in a previous
+- call to `setlocale'. One requirement is that the CATEGORY must be
+- the same in the call the string was returned and the one when the
+- string is passed in as LOCALE parameter.
+-
+- When you read the current locale for category `LC_ALL', the value
+- encodes the entire combination of selected locales for all
+- categories. In this case, the value is not just a single locale
+- name. In fact, we don't make any promises about what it looks
+- like. But if you specify the same "locale name" with `LC_ALL' in
+- a subsequent call to `setlocale', it restores the same combination
+- of locale selections.
+-
+- To be sure you can use the returned string encoding the currently
+- selected locale at a later time, you must make a copy of the
+- string. It is not guaranteed that the returned pointer remains
+- valid over time.
+-
+- When the LOCALE argument is not a null pointer, the string returned
+- by `setlocale' reflects the newly-modified locale.
+-
+- If you specify an empty string for LOCALE, this means to read the
+- appropriate environment variable and use its value to select the
+- locale for CATEGORY.
+-
+- If a nonempty string is given for LOCALE, then the locale of that
+- name is used if possible.
+-
+- If you specify an invalid locale name, `setlocale' returns a null
+- pointer and leaves the current locale unchanged.
+-
+- Here is an example showing how you might use `setlocale' to
+-temporarily switch to a new locale.
+-
+- #include <stddef.h>
+- #include <locale.h>
+- #include <stdlib.h>
+- #include <string.h>
+-
+- void
+- with_other_locale (char *new_locale,
+- void (*subroutine) (int),
+- int argument)
+- {
+- char *old_locale, *saved_locale;
+-
+- /* Get the name of the current locale. */
+- old_locale = setlocale (LC_ALL, NULL);
+-
+- /* Copy the name so it won't be clobbered by `setlocale'. */
+- saved_locale = strdup (old_locale);
+- if (saved_locale == NULL)
+- fatal ("Out of memory");
+-
+- /* Now change the locale and do some stuff with it. */
+- setlocale (LC_ALL, new_locale);
+- (*subroutine) (argument);
+-
+- /* Restore the original locale. */
+- setlocale (LC_ALL, saved_locale);
+- free (saved_locale);
+- }
+-
+- *Portability Note:* Some ISO C systems may define additional locale
+-categories, and future versions of the library will do so. For
+-portability, assume that any symbol beginning with `LC_' might be
+-defined in `locale.h'.

+-
+-Standard Locales
+-================
+-
+- The only locale names you can count on finding on all operating
+-systems are these three standard ones:
+-
+-`"C"'
+- This is the standard C locale. The attributes and behavior it
+- provides are specified in the ISO C standard. When your program
+- starts up, it initially uses this locale by default.
+-
+-`"POSIX"'
+- This is the standard POSIX locale. Currently, it is an alias for
+- the standard C locale.
+-
+-`""'
+- The empty name says to select a locale based on environment
+- variables. *Note Locale Categories::.
+-
+- Defining and installing named locales is normally a responsibility of
+-the system administrator at your site (or the person who installed the
+-GNU C library). It is also possible for the user to create private
+-locales. All this will be discussed later when describing the tool to
+-do so.
+-
+- If your program needs to use something other than the `C' locale, it
+-will be more portable if you use whatever locale the user specifies
+-with the environment, rather than trying to specify some non-standard
+-locale explicitly by name. Remember, different machines might have
+-different sets of locales installed.

+-
+-Accessing Locale Information
+-============================
+-
+- There are several ways to access locale information. The simplest
+-way is to let the C library itself do the work. Several of the
+-functions in this library implicitly access the locale data, and use
+-what information is provided by the currently selected locale. This is
+-how the locale model is meant to work normally.
+-
+- As an example take the `strftime' function, which is meant to nicely
+-format date and time information (*note Formatting Calendar Time::).
+-Part of the standard information contained in the `LC_TIME' category is
+-the names of the months. Instead of requiring the programmer to take
+-care of providing the translations the `strftime' function does this
+-all by itself. `%A' in the format string is replaced by the
+-appropriate weekday name of the locale currently selected by `LC_TIME'.
+-This is an easy example, and wherever possible functions do things
+-automatically in this way.
+-
+- But there are quite often situations when there is simply no function
+-to perform the task, or it is simply not possible to do the work
+-automatically. For these cases it is necessary to access the
+-information in the locale directly. To do this the C library provides
+-two functions: `localeconv' and `nl_langinfo'. The former is part of
+-ISO C and therefore portable, but has a brain-damaged interface. The
+-second is part of the Unix interface and is portable in as far as the
+-system follows the Unix standards.

+-
+-`localeconv': It is portable but ...
+-------------------------------------
+-
+- Together with the `setlocale' function the ISO C people invented the
+-`localeconv' function. It is a masterpiece of poor design. It is
+-expensive to use, not extendable, and not generally usable as it
+-provides access to only `LC_MONETARY' and `LC_NUMERIC' related
+-information. Nevertheless, if it is applicable to a given situation it
+-should be used since it is very portable. The function `strfmon'
+-formats monetary amounts according to the selected locale using this
+-information.
+-
+- - Function: struct lconv * localeconv (void)
+- The `localeconv' function returns a pointer to a structure whose
+- components contain information about how numeric and monetary
+- values should be formatted in the current locale.
+-
+- You should not modify the structure or its contents. The
+- structure might be overwritten by subsequent calls to
+- `localeconv', or by calls to `setlocale', but no other function in
+- the library overwrites this value.
+-
+- - Data Type: struct lconv
+- `localeconv''s return value is of this data type. Its elements are
+- described in the following subsections.
+-
+- If a member of the structure `struct lconv' has type `char', and the
+-value is `CHAR_MAX', it means that the current locale has no value for
+-that parameter.

+-
+-Generic Numeric Formatting Parameters
+-.....................................
+-
+- These are the standard members of `struct lconv'; there may be
+-others.
+-
+-`char *decimal_point'
+-`char *mon_decimal_point'
+- These are the decimal-point separators used in formatting
+- non-monetary and monetary quantities, respectively. In the `C'
+- locale, the value of `decimal_point' is `"."', and the value of
+- `mon_decimal_point' is `""'.
+-
+-`char *thousands_sep'
+-`char *mon_thousands_sep'
+- These are the separators used to delimit groups of digits to the
+- left of the decimal point in formatting non-monetary and monetary
+- quantities, respectively. In the `C' locale, both members have a
+- value of `""' (the empty string).
+-
+-`char *grouping'
+-`char *mon_grouping'
+- These are strings that specify how to group the digits to the left
+- of the decimal point. `grouping' applies to non-monetary
+- quantities and `mon_grouping' applies to monetary quantities. Use
+- either `thousands_sep' or `mon_thousands_sep' to separate the digit
+- groups.
+-
+- Each member of these strings is to be interpreted as an integer
+- value of type `char'. Successive numbers (from left to right)
+- give the sizes of successive groups (from right to left, starting
+- at the decimal point.) The last member is either `0', in which
+- case the previous member is used over and over again for all the
+- remaining groups, or `CHAR_MAX', in which case there is no more
+- grouping--or, put another way, any remaining digits form one large
+- group without separators.
+-
+- For example, if `grouping' is `"\04\03\02"', the correct grouping
+- for the number `123456787654321' is `12', `34', `56', `78', `765',
+- `4321'. This uses a group of 4 digits at the end, preceded by a
+- group of 3 digits, preceded by groups of 2 digits (as many as
+- needed). With a separator of `,', the number would be printed as
+- `12,34,56,78,765,4321'.
+-
+- A value of `"\03"' indicates repeated groups of three digits, as
+- normally used in the U.S.
+-
+- In the standard `C' locale, both `grouping' and `mon_grouping'
+- have a value of `""'. This value specifies no grouping at all.
+-
+-`char int_frac_digits'
+-`char frac_digits'
+- These are small integers indicating how many fractional digits (to
+- the right of the decimal point) should be displayed in a monetary
+- value in international and local formats, respectively. (Most
+- often, both members have the same value.)
+-
+- In the standard `C' locale, both of these members have the value
+- `CHAR_MAX', meaning "unspecified". The ISO standard doesn't say
+- what to do when you find this value; we recommend printing no
+- fractional digits. (This locale also specifies the empty string
+- for `mon_decimal_point', so printing any fractional digits would be
+- confusing!)

+-
+-Printing the Currency Symbol
+-............................
+-
+- These members of the `struct lconv' structure specify how to print
+-the symbol to identify a monetary value--the international analog of
+-`$' for US dollars.
+-
+- Each country has two standard currency symbols. The "local currency
+-symbol" is used commonly within the country, while the "international
+-currency symbol" is used internationally to refer to that country's
+-currency when it is necessary to indicate the country unambiguously.
+-
+- For example, many countries use the dollar as their monetary unit,
+-and when dealing with international currencies it's important to specify
+-that one is dealing with (say) Canadian dollars instead of U.S. dollars
+-or Australian dollars. But when the context is known to be Canada,
+-there is no need to make this explicit--dollar amounts are implicitly
+-assumed to be in Canadian dollars.
+-
+-`char *currency_symbol'
+- The local currency symbol for the selected locale.
+-
+- In the standard `C' locale, this member has a value of `""' (the
+- empty string), meaning "unspecified". The ISO standard doesn't
+- say what to do when you find this value; we recommend you simply
+- print the empty string as you would print any other string pointed
+- to by this variable.
+-
+-`char *int_curr_symbol'
+- The international currency symbol for the selected locale.
+-
+- The value of `int_curr_symbol' should normally consist of a
+- three-letter abbreviation determined by the international standard
+- `ISO 4217 Codes for the Representation of Currency and Funds',
+- followed by a one-character separator (often a space).
+-
+- In the standard `C' locale, this member has a value of `""' (the
+- empty string), meaning "unspecified". We recommend you simply
+- print the empty string as you would print any other string pointed
+- to by this variable.
+-
+-`char p_cs_precedes'
+-`char n_cs_precedes'
+-`char int_p_cs_precedes'
+-`char int_n_cs_precedes'
+- These members are `1' if the `currency_symbol' or
+- `int_curr_symbol' strings should precede the value of a monetary
+- amount, or `0' if the strings should follow the value. The
+- `p_cs_precedes' and `int_p_cs_precedes' members apply to positive
+- amounts (or zero), and the `n_cs_precedes' and `int_n_cs_precedes'
+- members apply to negative amounts.
+-
+- In the standard `C' locale, all of these members have a value of
+- `CHAR_MAX', meaning "unspecified". The ISO standard doesn't say
+- what to do when you find this value. We recommend printing the
+- currency symbol before the amount, which is right for most
+- countries. In other words, treat all nonzero values alike in
+- these members.
+-
+- The members with the `int_' prefix apply to the `int_curr_symbol'
+- while the other two apply to `currency_symbol'.
+-
+-`char p_sep_by_space'
+-`char n_sep_by_space'
+-`char int_p_sep_by_space'
+-`char int_n_sep_by_space'
+- These members are `1' if a space should appear between the
+- `currency_symbol' or `int_curr_symbol' strings and the amount, or
+- `0' if no space should appear. The `p_sep_by_space' and
+- `int_p_sep_by_space' members apply to positive amounts (or zero),
+- and the `n_sep_by_space' and `int_n_sep_by_space' members apply to
+- negative amounts.
+-
+- In the standard `C' locale, all of these members have a value of
+- `CHAR_MAX', meaning "unspecified". The ISO standard doesn't say
+- what you should do when you find this value; we suggest you treat
+- it as 1 (print a space). In other words, treat all nonzero values
+- alike in these members.
+-
+- The members with the `int_' prefix apply to the `int_curr_symbol'
+- while the other two apply to `currency_symbol'. There is one
+- specialty with the `int_curr_symbol', though. Since all legal
+- values contain a space at the end the string one either printf
+- this space (if the currency symbol must appear in front and must
+- be separated) or one has to avoid printing this character at all
+- (especially when at the end of the string).

+-Pinpoint Access to Locale Data
+-------------------------------
+-
+- When writing the X/Open Portability Guide the authors realized that
+-the `localeconv' function is not enough to provide reasonable access to
+-locale information. The information which was meant to be available in
+-the locale (as later specified in the POSIX.1 standard) requires more
+-ways to access it. Therefore the `nl_langinfo' function was introduced.
+-
+- - Function: char * nl_langinfo (nl_item ITEM)
+- The `nl_langinfo' function can be used to access individual
+- elements of the locale categories. Unlike the `localeconv'
+- function, which returns all the information, `nl_langinfo' lets
+- the caller select what information it requires. This is very fast
+- and it is not a problem to call this function multiple times.
+-
+- A second advantage is that in addition to the numeric and monetary
+- formatting information, information from the `LC_TIME' and
+- `LC_MESSAGES' categories is available.
+-
+- The type `nl_type' is defined in `nl_types.h'. The argument ITEM
+- is a numeric value defined in the header `langinfo.h'. The X/Open
+- standard defines the following values:
+-
+- `CODESET'
+- `nl_langinfo' returns a string with the name of the coded
+- character set used in the selected locale.

+-
+- `ERA'
+- The return value represents the era used in the current

+-
+- Most locales do not define this value. An example of a

+- Japan, the traditional representation of dates includes the
+- name of the era corresponding to the then-emperor's reign.
+-
+- Normally it should not be necessary to use this value

+-
+- `NOSTR'
+- The return value is a locale-specific translation of the

+-
+- The file `langinfo.h' defines a lot more symbols but none of them

+-
+- Note that the return value for any valid argument can be used for
+- in all situations (with the possible exception of the am/pm time
+- formatting codes). If the user has not selected any locale for the
+- appropriate category, `nl_langinfo' returns the information from
+- the `"C"' locale. It is therefore possible to use this function as
+- shown in the example below.
+-
+- If the argument ITEM is not valid, a pointer to an empty string is
+- returned.
+-
+- An example of `nl_langinfo' usage is a function which has to print a
+-given date and time in a locale-specific way. At first one might think
+-that, since `strftime' internally uses the locale information, writing
+-something like the following is enough:
+-
+- size_t
+- i18n_time_n_data (char *s, size_t len, const struct tm *tp)
+- {
+- return strftime (s, len, "%X %D", tp);
+- }
+-
+- The format contains no weekday or month names and therefore is
+-internationally usable. Wrong! The output produced is something like
+-`"hh:mm:ss MM/DD/YY"'. This format is only recognizable in the USA.
+-Other countries use different formats. Therefore the function should
+-be rewritten like this:
+-
+- size_t
+- i18n_time_n_data (char *s, size_t len, const struct tm *tp)
+- {
+- return strftime (s, len, nl_langinfo (D_T_FMT), tp);
+- }
+-
+- Now it uses the date and time format of the locale selected when the
+-program runs. If the user selects the locale correctly there should
+-never be a misunderstanding over the time and date format.

+-
+-A dedicated function to format numbers
+-======================================
+-
+- We have seen that the structure returned by `localeconv' as well as
+-the values given to `nl_langinfo' allow you to retrieve the various
+-pieces of locale-specific information to format numbers and monetary
+-amounts. We have also seen that the underlying rules are quite complex.
+-
+- Therefore the X/Open standards introduce a function which uses such
+-locale information, making it easier for the user to format numbers
+-according to these rules.
+-
+- - Function: ssize_t strfmon (char *S, size_t MAXSIZE, const char
+- *FORMAT, ...)
+- The `strfmon' function is similar to the `strftime' function in
+- that it takes a buffer, its size, a format string, and values to
+- write into the buffer as text in a form specified by the format
+- string. Like `strftime', the function also returns the number of
+- bytes written into the buffer.
+-
+- There are two differences: `strfmon' can take more than one
+- argument, and, of course, the format specification is different.
+- Like `strftime', the format string consists of normal text, which
+- is output as is, and format specifiers, which are indicated by a
+- `%'. Immediately after the `%', you can optionally specify
+- various flags and formatting information before the main
+- formatting character, in a similar way to `printf':
+-
+- * Immediately following the `%' there can be one or more of the
+- following flags:
+- `=F'
+- The single byte character F is used for this field as
+- the numeric fill character. By default this character
+- is a space character. Filling with this character is
+- only performed if a left precision is specified. It is
+- not just to fill to the given field width.
+-
+- `^'
+- The number is printed without grouping the digits
+- according to the rules of the current locale. By
+- default grouping is enabled.
+-
+- `+', `('
+- At most one of these flags can be used. They select
+- which format to represent the sign of a currency amount.
+- By default, and if `+' is given, the locale equivalent
+- of +/- is used. If `(' is given, negative amounts are
+- enclosed in parentheses. The exact format is determined
+- by the values of the `LC_MONETARY' category of the
+- locale selected at program runtime.
+-
+- `!'
+- The output will not contain the currency symbol.
+-
+- `-'
+- The output will be formatted left-justified instead of
+- right-justified if it does not fill the entire field
+- width.
+-
+- The next part of a specification is an optional field width. If no
+- width is specified 0 is taken. During output, the function first
+- determines how much space is required. If it requires at least as
+- many characters as given by the field width, it is output using as
+- much space as necessary. Otherwise, it is extended to use the
+- full width by filling with the space character. The presence or
+- absence of the `-' flag determines the side at which such padding
+- occurs. If present, the spaces are added at the right making the
+- output left-justified, and vice versa.
+-
+- So far the format looks familiar, being similar to the `printf' and
+- `strftime' formats. However, the next two optional fields
+- introduce something new. The first one is a `#' character followed
+- by a decimal digit string. The value of the digit string
+- specifies the number of _digit_ positions to the left of the
+- decimal point (or equivalent). This does _not_ include the
+- grouping character when the `^' flag is not given. If the space
+- needed to print the number does not fill the whole width, the
+- field is padded at the left side with the fill character, which
+- can be selected using the `=' flag and by default is a space. For
+- example, if the field width is selected as 6 and the number is
+- 123, the fill character is `*' the result will be `***123'.
+-
+- The second optional field starts with a `.' (period) and consists
+- of another decimal digit string. Its value describes the number of
+- characters printed after the decimal point. The default is
+- selected from the current locale (`frac_digits',
+- `int_frac_digits', see *note General Numeric::). If the exact
+- representation needs more digits than given by the field width,
+- the displayed value is rounded. If the number of fractional
+- digits is selected to be zero, no decimal point is printed.
+-
+- As a GNU extension, the `strfmon' implementation in the GNU libc
+- allows an optional `L' next as a format modifier. If this modifier
+- is given, the argument is expected to be a `long double' instead of
+- a `double' value.
+-
+- Finally, the last component is a format specifier. There are three
+- specifiers defined:
+-
+- `i'
+- Use the locale's rules for formatting an international
+- currency value.
+-
+- `n'
+- Use the locale's rules for formatting a national currency
+- value.
+-
+- `%'
+- Place a `%' in the output. There must be no flag, width
+- specifier or modifier given, only `%%' is allowed.
+-
+- As for `printf', the function reads the format string from left to
+- right and uses the values passed to the function following the
+- format string. The values are expected to be either of type
+- `double' or `long double', depending on the presence of the
+- modifier `L'. The result is stored in the buffer pointed to by S.
+- At most MAXSIZE characters are stored.
+-
+- The return value of the function is the number of characters
+- stored in S, including the terminating `NULL' byte. If the number
+- of characters stored would exceed MAXSIZE, the function returns -1
+- and the content of the buffer S is unspecified. In this case
+- `errno' is set to `E2BIG'.
+-
+- A few examples should make clear how the function works. It is
+-assumed that all the following pieces of code are executed in a program
+-which uses the USA locale (`en_US'). The simplest form of the format
+-is this:
+-
+- strfmon (buf, 100, "@%n@%n@%n@", 123.45, -567.89, 12345.678);
+-
+-The output produced is
+- "@$123.45@-$567.89@$12,345.68@"
+-
+- We can notice several things here. First, the widths of the output
+-numbers are different. We have not specified a width in the format
+-string, and so this is no wonder. Second, the third number is printed
+-using thousands separators. The thousands separator for the `en_US'
+-locale is a comma. The number is also rounded. .678 is rounded to .68
+-since the format does not specify a precision and the default value in
+-the locale is 2. Finally, note that the national currency symbol is
+-printed since `%n' was used, not `i'. The next example shows how we
+-can align the output.
+-
+- strfmon (buf, 100, "@%=*11n@%=*11n@%=*11n@", 123.45, -567.89, 12345.678);
+-
+-The output this time is:
+-
+- "@ $123.45@ -$567.89@ $12,345.68@"
+-
+- Two things stand out. Firstly, all fields have the same width
+-(eleven characters) since this is the width given in the format and
+-since no number required more characters to be printed. The second
+-important point is that the fill character is not used. This is
+-correct since the white space was not used to achieve a precision given
+-by a `#' modifier, but instead to fill to the given width. The
+-difference becomes obvious if we now add a width specification.
+-
+- strfmon (buf, 100, "@%=*11#5n@%=*11#5n@%=*11#5n@",
+- 123.45, -567.89, 12345.678);
+-
+-The output is
+-
+- "@ $***123.45@-$***567.89@ $12,456.68@"
+-
+- Here we can see that all the currency symbols are now aligned, and
+-that the space between the currency sign and the number is filled with
+-the selected fill character. Note that although the width is selected
+-to be 5 and 123.45 has three digits left of the decimal point, the
+-space is filled with three asterisks. This is correct since, as
+-explained above, the width does not include the positions used to store
+-thousands separators. One last example should explain the remaining
+-functionality.
+-
+- strfmon (buf, 100, "@%=0(16#5.3i@%=0(16#5.3i@%=0(16#5.3i@",
+- 123.45, -567.89, 12345.678);
+-
+-This rather complex format string produces the following output:
+-
+- "@ USD 000123,450 @(USD 000567.890)@ USD 12,345.678 @"
+-
+- The most noticeable change is the alternative way of representing
+-negative numbers. In financial circles this is often done using
+-parentheses, and this is what the `(' flag selected. The fill
+-character is now `0'. Note that this `0' character is not regarded as
+-a numeric zero, and therefore the first and second numbers are not
+-printed using a thousands separator. Since we used the format
+-specifier `i' instead of `n', the international form of the currency
+-symbol is used. This is a four letter string, in this case `"USD "'.
+-The last point is that since the precision right of the decimal point
+-is selected to be three, the first and second numbers are printed with
+-an extra zero at the end and the third number is printed without
+-rounding.

+-Yes-or-No Questions
+-===================
+-
+- Some non GUI programs ask a yes-or-no question. If the messages
+-(especially the questions) are translated into foreign languages, be
+-sure that you localize the answers too. It would be very bad habit to
+-ask a question in one language and request the answer in another, often
+-English.
+-
+- The GNU C library contains `rpmatch' to give applications easy
+-access to the corresponding locale definitions.
+-
+- - Function: int rpmatch (const char *RESPONSE)
+- The function `rpmatch' checks the string in RESPONSE whether or
+- not it is a correct yes-or-no answer and if yes, which one. The
+- check uses the `YESEXPR' and `NOEXPR' data in the `LC_MESSAGES'
+- category of the currently selected locale. The return value is as
+- follows:
+-
+- `1'
+- The user entered an affirmative answer.
+-
+- `0'
+- The user entered a negative answer.
+-
+- `-1'
+- The answer matched neither the `YESEXPR' nor the `NOEXPR'
+- regular expression.
+-
+- This function is not standardized but available beside in GNU libc
+- at least also in the IBM AIX library.
+-
+-This function would normally be used like this:
+-
+- ...
+- /* Use a safe default. */
+- _Bool doit = false;
+-
+- fputs (gettext ("Do you really want to do this? "), stdout);
+- fflush (stdout);
+- /* Prepare the `getline' call. */
+- line = NULL;
+- len = 0;
+- while (getline (&line, &len, stdout) >= 0)
+- {
+- /* Check the response. */
+- int res = rpmatch (line);
+- if (res >= 0)
+- {
+- /* We got a definitive answer. */
+- if (res > 0)
+- doit = true;
+- break;
+- }
+- }
+- /* Free what `getline' allocated. */
+- free (line);
+-
+- Note that the loop continues until an read error is detected or
+-until a definitive (positive or negative) answer is read.

+-Message Translation
+-*******************
+-
+- The program's interface with the human should be designed in a way to
+-ease the human the task. One of the possibilities is to use messages in
+-whatever language the user prefers.
+-
+- Printing messages in different languages can be implemented in
+-different ways. One could add all the different languages in the
+-source code and add among the variants every time a message has to be
+-printed. This is certainly no good solution since extending the set of
+-languages is difficult (the code must be changed) and the code itself
+-can become really big with dozens of message sets.
+-
+- A better solution is to keep the message sets for each language are
+-kept in separate files which are loaded at runtime depending on the
+-language selection of the user.
+-
+- The GNU C Library provides two different sets of functions to support
+-message translation. The problem is that neither of the interfaces is
+-officially defined by the POSIX standard. The `catgets' family of
+-functions is defined in the X/Open standard but this is derived from
+-industry decisions and therefore not necessarily based on reasonable
+-decisions.
+-
+- As mentioned above the message catalog handling provides easy
+-extendibility by using external data files which contain the message
+-translations. I.e., these files contain for each of the messages used
+-in the program a translation for the appropriate language. So the tasks
+-of the message handling functions are
+-
+- * locate the external data file with the appropriate translations.
+-
+- * load the data and make it possible to address the messages
+-
+- * map a given key to the translated message
+-
+- The two approaches mainly differ in the implementation of this last
+-step. The design decisions made for this influences the whole rest.

+-X/Open Message Catalog Handling
+-===============================
+-
+- The `catgets' functions are based on the simple scheme:
+-
+- Associate every message to translate in the source code with a
+- unique identifier. To retrieve a message from a catalog file
+- solely the identifier is used.
+-
+- This means for the author of the program that s/he will have to make
+-sure the meaning of the identifier in the program code and in the
+-message catalogs are always the same.
+-
+- Before a message can be translated the catalog file must be located.
+-The user of the program must be able to guide the responsible function
+-to find whatever catalog the user wants. This is separated from what
+-the programmer had in mind.
+-
+- All the types, constants and functions for the `catgets' functions
+-are defined/declared in the `nl_types.h' header file.

+-
+- - Function: nl_catd catopen (const char *CAT_NAME, int FLAG)
+- The `catgets' function tries to locate the message data file names
+- CAT_NAME and loads it when found. The return value is of an
+- opaque type and can be used in calls to the other functions to
+- refer to this loaded catalog.
+-
+- The return value is `(nl_catd) -1' in case the function failed and
+- no catalog was loaded. The global variable ERRNO contains a code
+- for the error causing the failure. But even if the function call
+- succeeded this does not mean that all messages can be translated.
+-
+- Locating the catalog file must happen in a way which lets the user
+- of the program influence the decision. It is up to the user to
+- decide about the language to use and sometimes it is useful to use
+- alternate catalog files. All this can be specified by the user by
+- setting some environment variables.
+-
+- The first problem is to find out where all the message catalogs are
+- stored. Every program could have its own place to keep all the
+- different files but usually the catalog files are grouped by
+- languages and the catalogs for all programs are kept in the same
+- place.
+-
+- To tell the `catopen' function where the catalog for the program
+- can be found the user can set the environment variable `NLSPATH' to
+- a value which describes her/his choice. Since this value must be
+- usable for different languages and locales it cannot be a simple
+- string. Instead it is a format string (similar to `printf''s).
+- An example is
+-
+- /usr/share/locale/%L/%N:/usr/share/locale/%L/LC_MESSAGES/%N
+-
+- First one can see that more than one directory can be specified
+- (with the usual syntax of separating them by colons). The next
+- things to observe are the format string, `%L' and `%N' in this
+- case. The `catopen' function knows about several of them and the
+- replacement for all of them is of course different.
+-
+- `%N'
+- This format element is substituted with the name of the
+- catalog file. This is the value of the CAT_NAME argument
+- given to `catgets'.
+-
+- `%L'
+- This format element is substituted with the name of the
+- currently selected locale for translating messages. How this
+- is determined is explained below.
+-
+- `%l'
+- (This is the lowercase ell.) This format element is
+- substituted with the language element of the locale name.
+- The string describing the selected locale is expected to have
+- the form `LANG[_TERR[.CODESET]]' and this format uses the
+- first part LANG.
+-
+- `%t'
+- This format element is substituted by the territory part TERR
+- of the name of the currently selected locale. See the
+- explanation of the format above.
+-
+- `%c'
+- This format element is substituted by the codeset part
+- CODESET of the name of the currently selected locale. See
+- the explanation of the format above.
+-
+- `%%'
+- Since `%' is used in a meta character there must be a way to
+- express the `%' character in the result itself. Using `%%'
+- does this just like it works for `printf'.
+-
+- Using `NLSPATH' allows arbitrary directories to be searched for
+- message catalogs while still allowing different languages to be
+- used. If the `NLSPATH' environment variable is not set, the
+- default value is
+-
+- PREFIX/share/locale/%L/%N:PREFIX/share/locale/%L/LC_MESSAGES/%N
+-
+- where PREFIX is given to `configure' while installing the GNU C
+- Library (this value is in many cases `/usr' or the empty string).
+-
+- The remaining problem is to decide which must be used. The value
+- decides about the substitution of the format elements mentioned
+- above. First of all the user can specify a path in the message
+- catalog name (i.e., the name contains a slash character). In this
+- situation the `NLSPATH' environment variable is not used. The
+- catalog must exist as specified in the program, perhaps relative
+- to the current working directory. This situation in not desirable
+- and catalogs names never should be written this way. Beside this,
+- this behavior is not portable to all other platforms providing the
+- `catgets' interface.
+-
+- Otherwise the values of environment variables from the standard
+- environment are examined (*note Standard Environment::). Which
+- variables are examined is decided by the FLAG parameter of
+- `catopen'. If the value is `NL_CAT_LOCALE' (which is defined in
+- `nl_types.h') then the `catopen' function use the name of the
+- locale currently selected for the `LC_MESSAGES' category.
+-
+- If FLAG is zero the `LANG' environment variable is examined. This
+- is a left-over from the early days where the concept of the locales
+- had not even reached the level of POSIX locales.
+-
+- The environment variable and the locale name should have a value
+- of the form `LANG[_TERR[.CODESET]]' as explained above. If no
+- environment variable is set the `"C"' locale is used which
+- prevents any translation.
+-
+- The return value of the function is in any case a valid string.
+- Either it is a translation from a message catalog or it is the
+- same as the STRING parameter. So a piece of code to decide
+- whether a translation actually happened must look like this:
+-
+- {
+- char *trans = catgets (desc, set, msg, input_string);
+- if (trans == input_string)
+- {
+- /* Something went wrong. */
+- }
+- }
+-
+- When an error occurred the global variable ERRNO is set to
+-
+- EBADF
+- The catalog does not exist.
+-
+- ENOMSG
+- The set/message tuple does not name an existing element in the
+- message catalog.
+-
+- While it sometimes can be useful to test for errors programs
+- normally will avoid any test. If the translation is not available
+- it is no big problem if the original, untranslated message is
+- printed. Either the user understands this as well or s/he will
+- look for the reason why the messages are not translated.
+-
+- Please note that the currently selected locale does not depend on a
+-call to the `setlocale' function. It is not necessary that the locale
+-data files for this locale exist and calling `setlocale' succeeds. The
+-`catopen' function directly reads the values of the environment
+-variables.
+-
+- - Function: char * catgets (nl_catd CATALOG_DESC, int SET, int
+- MESSAGE, const char *STRING)
+- The function `catgets' has to be used to access the massage catalog
+- previously opened using the `catopen' function. The CATALOG_DESC
+- parameter must be a value previously returned by `catopen'.
+-
+- The next two parameters, SET and MESSAGE, reflect the internal
+- organization of the message catalog files. This will be explained
+- in detail below. For now it is interesting to know that a catalog
+- can consists of several set and the messages in each thread are
+- individually numbered using numbers. Neither the set number nor
+- the message number must be consecutive. They can be arbitrarily
+- chosen. But each message (unless equal to another one) must have
+- its own unique pair of set and message number.
+-
+- Since it is not guaranteed that the message catalog for the
+- language selected by the user exists the last parameter STRING
+- helps to handle this case gracefully. If no matching string can
+- be found STRING is returned. This means for the programmer that
+-
+- * the STRING parameters should contain reasonable text (this
+- also helps to understand the program seems otherwise there
+- would be no hint on the string which is expected to be
+- returned.
+-
+- * all STRING arguments should be written in the same language.
+-
+- It is somewhat uncomfortable to write a program using the `catgets'
+-functions if no supporting functionality is available. Since each
+-set/message number tuple must be unique the programmer must keep lists
+-of the messages at the same time the code is written. And the work
+-between several people working on the same project must be coordinated.
+-We will see some how these problems can be relaxed a bit (*note Common
+-Usage::).
+-
+- - Function: int catclose (nl_catd CATALOG_DESC)
+- The `catclose' function can be used to free the resources
+- associated with a message catalog which previously was opened by a
+- call to `catopen'. If the resources can be successfully freed the
+- function returns `0'. Otherwise it return `-1' and the global
+- variable ERRNO is set. Errors can occur if the catalog descriptor
+- CATALOG_DESC is not valid in which case ERRNO is set to `EBADF'.

+-
+-Format of the message catalog files
+------------------------------------
+-
+- The only reasonable way the translate all the messages of a function
+-and store the result in a message catalog file which can be read by the
+-`catopen' function is to write all the message text to the translator
+-and let her/him translate them all. I.e., we must have a file with
+-entries which associate the set/message tuple with a specific
+-translation. This file format is specified in the X/Open standard and
+-is as follows:
+-
+- * Lines containing only whitespace characters or empty lines are
+- ignored.
+-
+- * Lines which contain as the first non-whitespace character a `$'
+- followed by a whitespace character are comment and are also
+- ignored.
+-
+- * If a line contains as the first non-whitespace characters the
+- sequence `$set' followed by a whitespace character an additional
+- argument is required to follow. This argument can either be:
+-
+- - a number. In this case the value of this number determines
+- the set to which the following messages are added.
+-
+- - an identifier consisting of alphanumeric characters plus the
+- underscore character. In this case the set get automatically
+- a number assigned. This value is one added to the largest
+- set number which so far appeared.
+-
+- How to use the symbolic names is explained in section *Note
+- Common Usage::.
+-
+- It is an error if a symbol name appears more than once. All
+- following messages are placed in a set with this number.
+-
+- * If a line contains as the first non-whitespace characters the
+- sequence `$delset' followed by a whitespace character an
+- additional argument is required to follow. This argument can
+- either be:
+-
+- - a number. In this case the value of this number determines
+- the set which will be deleted.
+-
+- - an identifier consisting of alphanumeric characters plus the
+- underscore character. This symbolic identifier must match a
+- name for a set which previously was defined. It is an error
+- if the name is unknown.
+-
+- In both cases all messages in the specified set will be removed.
+- They will not appear in the output. But if this set is later
+- again selected with a `$set' command again messages could be added
+- and these messages will appear in the output.
+-
+- * If a line contains after leading whitespaces the sequence
+- `$quote', the quoting character used for this input file is
+- changed to the first non-whitespace character following the
+- `$quote'. If no non-whitespace character is present before the
+- line ends quoting is disable.
+-
+- By default no quoting character is used. In this mode strings are
+- terminated with the first unescaped line break. If there is a
+- `$quote' sequence present newline need not be escaped. Instead a
+- string is terminated with the first unescaped appearance of the
+- quote character.
+-
+- A common usage of this feature would be to set the quote character
+- to `"'. Then any appearance of the `"' in the strings must be
+- escaped using the backslash (i.e., `\"' must be written).
+-
+- * Any other line must start with a number or an alphanumeric
+- identifier (with the underscore character included). The
+- following characters (starting after the first whitespace
+- character) will form the string which gets associated with the
+- currently selected set and the message number represented by the
+- number and identifier respectively.
+-
+- If the start of the line is a number the message number is
+- obvious. It is an error if the same message number already
+- appeared for this set.
+-
+- If the leading token was an identifier the message number gets
+- automatically assigned. The value is the current maximum messages
+- number for this set plus one. It is an error if the identifier was
+- already used for a message in this set. It is OK to reuse the
+- identifier for a message in another thread. How to use the
+- symbolic identifiers will be explained below (*note Common
+- Usage::). There is one limitation with the identifier: it must
+- not be `Set'. The reason will be explained below.
+-
+- The text of the messages can contain escape characters. The usual
+- bunch of characters known from the ISO C language are recognized
+- (`\n', `\t', `\v', `\b', `\r', `\f', `\\', and `\NNN', where NNN
+- is the octal coding of a character code).
+-
+- *Important:* The handling of identifiers instead of numbers for the
+-set and messages is a GNU extension. Systems strictly following the
+-X/Open specification do not have this feature. An example for a message
+-catalog file is this:
+-
+- $ This is a leading comment.
+- $quote "
+-
+- $set SetOne
+- 1 Message with ID 1.
+- two " Message with ID \"two\", which gets the value 2 assigned"
+-
+- $set SetTwo
+- $ Since the last set got the number 1 assigned this set has number 2.
+- 4000 "The numbers can be arbitrary, they need not start at one."
+-
+- This small example shows various aspects:
+- * Lines 1 and 9 are comments since they start with `$' followed by a
+- whitespace.
+-
+- * The quoting character is set to `"'. Otherwise the quotes in the
+- message definition would have to be left away and in this case the
+- message with the identifier `two' would loose its leading
+- whitespace.
+-
+- * Mixing numbered messages with message having symbolic names is no
+- problem and the numbering happens automatically.
+-
+- While this file format is pretty easy it is not the best possible for
+-use in a running program. The `catopen' function would have to parser
+-the file and handle syntactic errors gracefully. This is not so easy
+-and the whole process is pretty slow. Therefore the `catgets'
+-functions expect the data in another more compact and ready-to-use file
+-format. There is a special program `gencat' which is explained in
+-detail in the next section.
+-
+- Files in this other format are not human readable. To be easy to
+-use by programs it is a binary file. But the format is byte order
+-independent so translation files can be shared by systems of arbitrary
+-architecture (as long as they use the GNU C Library).
+-
+- Details about the binary file format are not important to know since
+-these files are always created by the `gencat' program. The sources of
+-the GNU C Library also provide the sources for the `gencat' program and
+-so the interested reader can look through these source files to learn
+-about the file format.

+-
+-Generate Message Catalogs files
+--------------------------------
+-
+- The `gencat' program is specified in the X/Open standard and the GNU
+-implementation follows this specification and so processes all
+-correctly formed input files. Additionally some extension are
+-implemented which help to work in a more reasonable way with the
+-`catgets' functions.
+-
+- The `gencat' program can be invoked in two ways:
+-
+- `gencat [OPTION]... [OUTPUT-FILE [INPUT-FILE]...]`
+-
+- This is the interface defined in the X/Open standard. If no
+-INPUT-FILE parameter is given input will be read from standard input.
+-Multiple input files will be read as if they are concatenated. If
+-OUTPUT-FILE is also missing, the output will be written to standard
+-output. To provide the interface one is used to from other programs a
+-second interface is provided.
+-
+- `gencat [OPTION]... -o OUTPUT-FILE [INPUT-FILE]...`
+-
+- The option `-o' is used to specify the output file and all file
+-arguments are used as input files.
+-
+- Beside this one can use `-' or `/dev/stdin' for INPUT-FILE to denote
+-the standard input. Corresponding one can use `-' and `/dev/stdout'
+-for OUTPUT-FILE to denote standard output. Using `-' as a file name is
+-allowed in X/Open while using the device names is a GNU extension.
+-
+- The `gencat' program works by concatenating all input files and then
+-*merge* the resulting collection of message sets with a possibly
+-existing output file. This is done by removing all messages with
+-set/message number tuples matching any of the generated messages from
+-the output file and then adding all the new messages. To regenerate a
+-catalog file while ignoring the old contents therefore requires to
+-remove the output file if it exists. If the output is written to
+-standard output no merging takes place.
+-
+-The following table shows the options understood by the `gencat'
+-program. The X/Open standard does not specify any option for the
+-program so all of these are GNU extensions.
+-
+-`-V'
+-`--version'
+- Print the version information and exit.
+-
+-`-h'
+-`--help'
+- Print a usage message listing all available options, then exit
+- successfully.
+-
+-`--new'
+- Do never merge the new messages from the input files with the old
+- content of the output files. The old content of the output file
+- is discarded.
+-
+-`-H'
+-`--header=name'
+- This option is used to emit the symbolic names given to sets and
+- messages in the input files for use in the program. Details about
+- how to use this are given in the next section. The NAME parameter
+- to this option specifies the name of the output file. It will
+- contain a number of C preprocessor `#define's to associate a name
+- with a number.
+-
+- Please note that the generated file only contains the symbols from
+- the input files. If the output is merged with the previous
+- content of the output file the possibly existing symbols from the
+- file(s) which generated the old output files are not in the
+- generated header file.

+-
+-How to use the `catgets' interface
+-----------------------------------
+-
+- The `catgets' functions can be used in two different ways. By
+-following slavishly the X/Open specs and not relying on the extension
+-and by using the GNU extensions. We will take a look at the former
+-method first to understand the benefits of extensions.
+-
+-Not using symbolic names
+-........................
+-
+- Since the X/Open format of the message catalog files does not allow
+-symbol names we have to work with numbers all the time. When we start
+-writing a program we have to replace all appearances of translatable
+-strings with something like
+-
+- catgets (catdesc, set, msg, "string")
+-
+-CATGETS is retrieved from a call to `catopen' which is normally done
+-once at the program start. The `"string"' is the string we want to
+-translate. The problems start with the set and message numbers.
+-
+- In a bigger program several programmers usually work at the same
+-time on the program and so coordinating the number allocation is
+-crucial. Though no two different strings must be indexed by the same
+-tuple of numbers it is highly desirable to reuse the numbers for equal
+-strings with equal translations (please note that there might be
+-strings which are equal in one language but have different translations
+-due to difference contexts).
+-
+- The allocation process can be relaxed a bit by different set numbers
+-for different parts of the program. So the number of developers who
+-have to coordinate the allocation can be reduced. But still lists must
+-be keep track of the allocation and errors can easily happen. These
+-errors cannot be discovered by the compiler or the `catgets' functions.
+-Only the user of the program might see wrong messages printed. In the
+-worst cases the messages are so irritating that they cannot be
+-recognized as wrong. Think about the translations for `"true"' and
+-`"false"' being exchanged. This could result in a disaster.
+-
+-Using symbolic names
+-....................
+-
+- The problems mentioned in the last section derive from the fact that:
+-
+- 1. the numbers are allocated once and due to the possibly frequent
+- use of them it is difficult to change a number later.
+-
+- 2. the numbers do not allow to guess anything about the string and
+- therefore collisions can easily happen.
+-
+- By constantly using symbolic names and by providing a method which
+-maps the string content to a symbolic name (however this will happen)
+-one can prevent both problems above. The cost of this is that the
+-programmer has to write a complete message catalog file while s/he is
+-writing the program itself.
+-
+- This is necessary since the symbolic names must be mapped to numbers
+-before the program sources can be compiled. In the last section it was
+-described how to generate a header containing the mapping of the names.
+-E.g., for the example message file given in the last section we could
+-call the `gencat' program as follow (assume `ex.msg' contains the
+-sources).
+-
+- gencat -H ex.h -o ex.cat ex.msg
+-
+-This generates a header file with the following content:
+-
+- #define SetTwoSet 0x2 /* ex.msg:8 */
+-
+- #define SetOneSet 0x1 /* ex.msg:4 */
+- #define SetOnetwo 0x2 /* ex.msg:6 */
+-
+- As can be seen the various symbols given in the source file are
+-mangled to generate unique identifiers and these identifiers get numbers
+-assigned. Reading the source file and knowing about the rules will
+-allow to predict the content of the header file (it is deterministic)
+-but this is not necessary. The `gencat' program can take care for
+-everything. All the programmer has to do is to put the generated header
+-file in the dependency list of the source files of her/his project and
+-to add a rules to regenerate the header of any of the input files
+-change.
+-
+- One word about the symbol mangling. Every symbol consists of two
+-parts: the name of the message set plus the name of the message or the
+-special string `Set'. So `SetOnetwo' means this macro can be used to
+-access the translation with identifier `two' in the message set
+-`SetOne'.
+-
+- The other names denote the names of the message sets. The special
+-string `Set' is used in the place of the message identifier.
+-
+- If in the code the second string of the set `SetOne' is used the C
+-code should look like this:
+-
+- catgets (catdesc, SetOneSet, SetOnetwo,
+- " Message with ID \"two\", which gets the value 2 assigned")
+-
+- Writing the function this way will allow to change the message number
+-and even the set number without requiring any change in the C source
+-code. (The text of the string is normally not the same; this is only
+-for this example.)
+-
+-How does to this allow to develop
+-.................................
+-
+- To illustrate the usual way to work with the symbolic version numbers
+-here is a little example. Assume we want to write the very complex and
+-famous greeting program. We start by writing the code as usual:
+-
+- #include <stdio.h>
+- int
+- main (void)
+- {
+- printf ("Hello, world!\n");
+- return 0;
+- }
+-
+- Now we want to internationalize the message and therefore replace the
+-message with whatever the user wants.
+-
+- #include <nl_types.h>
+- #include <stdio.h>
+- #include "msgnrs.h"
+- int
+- main (void)
+- {
+- nl_catd catdesc = catopen ("hello.cat", NL_CAT_LOCALE);
+- printf (catgets (catdesc, SetMainSet, SetMainHello,
+- "Hello, world!\n"));
+- catclose (catdesc);
+- return 0;
+- }
+-
+- We see how the catalog object is opened and the returned descriptor
+-used in the other function calls. It is not really necessary to check
+-for failure of any of the functions since even in these situations the
+-functions will behave reasonable. They simply will be return a
+-translation.
+-
+- What remains unspecified here are the constants `SetMainSet' and
+-`SetMainHello'. These are the symbolic names describing the message.
+-To get the actual definitions which match the information in the
+-catalog file we have to create the message catalog source file and
+-process it using the `gencat' program.
+-
+- $ Messages for the famous greeting program.
+- $quote "
+-
+- $set Main
+- Hello "Hallo, Welt!\n"
+-
+- Now we can start building the program (assume the message catalog
+-source file is named `hello.msg' and the program source file `hello.c'):
+-
+- % gencat -H msgnrs.h -o hello.cat hello.msg
+- % cat msgnrs.h
+- #define MainSet 0x1 /* hello.msg:4 */
+- #define MainHello 0x1 /* hello.msg:5 */
+- % gcc -o hello hello.c -I.
+- % cp hello.cat /usr/share/locale/de/LC_MESSAGES
+- % echo $LC_ALL
+- de
+- % ./hello
+- Hallo, Welt!
+- %
+-
+- The call of the `gencat' program creates the missing header file
+-`msgnrs.h' as well as the message catalog binary. The former is used
+-in the compilation of `hello.c' while the later is placed in a
+-directory in which the `catopen' function will try to locate it.
+-Please check the `LC_ALL' environment variable and the default path for
+-`catopen' presented in the description above.

+-The Uniforum approach to Message Translation
+-============================================
+-
+- Sun Microsystems tried to standardize a different approach to message
+-translation in the Uniforum group. There never was a real standard
+-defined but still the interface was used in Sun's operation systems.
+-Since this approach fits better in the development process of free
+-software it is also used throughout the GNU project and the GNU
+-`gettext' package provides support for this outside the GNU C Library.
+-
+- The code of the `libintl' from GNU `gettext' is the same as the code
+-in the GNU C Library. So the documentation in the GNU `gettext' manual
+-is also valid for the functionality here. The following text will
+-describe the library functions in detail. But the numerous helper
+-programs are not described in this manual. Instead people should read
+-the GNU `gettext' manual (*note GNU gettext utilities: (gettext)Top.).
+-We will only give a short overview.
+-
+- Though the `catgets' functions are available by default on more
+-systems the `gettext' interface is at least as portable as the former.
+-The GNU `gettext' package can be used wherever the functions are not
+-available.

+-The `gettext' family of functions
+----------------------------------
+-
+- The paradigms underlying the `gettext' approach to message
+-translations is different from that of the `catgets' functions the
+-basic functionally is equivalent. There are functions of the following

+-
+-What has to be done to translate a message?
+-...........................................
+-
+- The `gettext' functions have a very simple interface. The most
+-basic function just takes the string which shall be translated as the
+-argument and it returns the translation. This is fundamentally
+-different from the `catgets' approach where an extra key is necessary
+-and the original string is only used for the error case.
+-
+- If the string which has to be translated is the only argument this of
+-course means the string itself is the key. I.e., the translation will
+-be selected based on the original string. The message catalogs must
+-therefore contain the original strings plus one translation for any such
+-string. The task of the `gettext' function is it to compare the
+-argument string with the available strings in the catalog and return the
+-appropriate translation. Of course this process is optimized so that
+-this process is not more expensive than an access using an atomic key
+-like in `catgets'.
+-
+- The `gettext' approach has some advantages but also some
+-disadvantages. Please see the GNU `gettext' manual for a detailed
+-discussion of the pros and cons.
+-
+- All the definitions and declarations for `gettext' can be found in
+-the `libintl.h' header file. On systems where these functions are not
+-part of the C library they can be found in a separate library named
+-`libintl.a' (or accordingly different for shared libraries).
+-
+- - Function: char * gettext (const char *MSGID)
+- The `gettext' function searches the currently selected message
+- catalogs for a string which is equal to MSGID. If there is such a
+- string available it is returned. Otherwise the argument string
+- MSGID is returned.
+-
+- Please note that all though the return value is `char *' the
+- returned string must not be changed. This broken type results
+- from the history of the function and does not reflect the way the
+- function should be used.
+-
+- Please note that above we wrote "message catalogs" (plural). This
+- is a specialty of the GNU implementation of these functions and we
+- will say more about this when we talk about the ways message
+- catalogs are selected (*note Locating gettext catalog::).
+-
+- The `gettext' function does not modify the value of the global
+- ERRNO variable. This is necessary to make it possible to write
+- something like
+-
+- printf (gettext ("Operation failed: %m\n"));
+-
+- Here the ERRNO value is used in the `printf' function while
+- processing the `%m' format element and if the `gettext' function
+- would change this value (it is called before `printf' is called)
+- we would get a wrong message.
+-
+- So there is no easy way to detect a missing message catalog beside
+- comparing the argument string with the result. But it is normally
+- the task of the user to react on missing catalogs. The program
+- cannot guess when a message catalog is really necessary since for
+- a user who speaks the language the program was developed in does
+- not need any translation.
+-
+- The remaining two functions to access the message catalog add some
+-functionality to select a message catalog which is not the default one.
+-This is important if parts of the program are developed independently.
+-Every part can have its own message catalog and all of them can be used
+-at the same time. The C library itself is an example: internally it
+-uses the `gettext' functions but since it must not depend on a
+-currently selected default message catalog it must specify all ambiguous
+-information.
+-
+- - Function: char * dgettext (const char *DOMAINNAME, const char *MSGID)
+- The `dgettext' functions acts just like the `gettext' function.
+- It only takes an additional first argument DOMAINNAME which guides
+- the selection of the message catalogs which are searched for the
+- translation. If the DOMAINNAME parameter is the null pointer the
+- `dgettext' function is exactly equivalent to `gettext' since the
+- default value for the domain name is used.
+-
+- As for `gettext' the return value type is `char *' which is an
+- anachronism. The returned string must never be modified.
+-
+- - Function: char * dcgettext (const char *DOMAINNAME, const char
+- *MSGID, int CATEGORY)
+- The `dcgettext' adds another argument to those which `dgettext'
+- takes. This argument CATEGORY specifies the last piece of
+- information needed to localize the message catalog. I.e., the
+- domain name and the locale category exactly specify which message
+- catalog has to be used (relative to a given directory, see below).
+-
+- The `dgettext' function can be expressed in terms of `dcgettext'
+- by using
+-
+- dcgettext (domain, string, LC_MESSAGES)
+-
+- instead of
+-
+- dgettext (domain, string)
+-
+- This also shows which values are expected for the third parameter.
+- One has to use the available selectors for the categories
+- available in `locale.h'. Normally the available values are
+- `LC_CTYPE', `LC_COLLATE', `LC_MESSAGES', `LC_MONETARY',
+- `LC_NUMERIC', and `LC_TIME'. Please note that `LC_ALL' must not
+- be used and even though the names might suggest this, there is no
+- relation to the environments variables of this name.
+-
+- The `dcgettext' function is only implemented for compatibility with
+- other systems which have `gettext' functions. There is not really
+- any situation where it is necessary (or useful) to use a different
+- value but `LC_MESSAGES' in for the CATEGORY parameter. We are
+- dealing with messages here and any other choice can only be
+- irritating.
+-
+- As for `gettext' the return value type is `char *' which is an
+- anachronism. The returned string must never be modified.
+-
+- When using the three functions above in a program it is a frequent
+-case that the MSGID argument is a constant string. So it is worth to
+-optimize this case. Thinking shortly about this one will realize that
+-as long as no new message catalog is loaded the translation of a message
+-will not change. This optimization is actually implemented by the
+-`gettext', `dgettext' and `dcgettext' functions.

+-
+-How to determine which catalog to be used
+-.........................................
+-
+- The functions to retrieve the translations for a given message have a
+-remarkable simple interface. But to provide the user of the program
+-still the opportunity to select exactly the translation s/he wants and
+-also to provide the programmer the possibility to influence the way to
+-locate the search for catalogs files there is a quite complicated
+-underlying mechanism which controls all this. The code is complicated
+-the use is easy.
+-
+- Basically we have two different tasks to perform which can also be
+-performed by the `catgets' functions:
+-
+- 1. Locate the set of message catalogs. There are a number of files
+- for different languages and which all belong to the package.
+- Usually they are all stored in the filesystem below a certain
+- directory.
+-
+- There can be arbitrary many packages installed and they can follow
+- different guidelines for the placement of their files.
+-
+- 2. Relative to the location specified by the package the actual
+- translation files must be searched, based on the wishes of the
+- user. I.e., for each language the user selects the program should
+- be able to locate the appropriate file.
+-
+- This is the functionality required by the specifications for
+-`gettext' and this is also what the `catgets' functions are able to do.
+-But there are some problems unresolved:
+-
+- * The language to be used can be specified in several different ways.
+- There is no generally accepted standard for this and the user
+- always expects the program understand what s/he means. E.g., to
+- select the German translation one could write `de', `german', or
+- `deutsch' and the program should always react the same.
+-
+- * Sometimes the specification of the user is too detailed. If s/he,
+- e.g., specifies `de_DE.ISO-8859-1' which means German, spoken in
+- Germany, coded using the ISO 8859-1 character set there is the
+- possibility that a message catalog matching this exactly is not
+- available. But there could be a catalog matching `de' and if the
+- character set used on the machine is always ISO 8859-1 there is no
+- reason why this later message catalog should not be used. (We
+- call this "message inheritance".)
+-
+- * If a catalog for a wanted language is not available it is not
+- always the second best choice to fall back on the language of the
+- developer and simply not translate any message. Instead a user
+- might be better able to read the messages in another language and
+- so the user of the program should be able to define an precedence
+- order of languages.
+-
+- We can divide the configuration actions in two parts: the one is
+-performed by the programmer, the other by the user. We will start with
+-the functions the programmer can use since the user configuration will
+-be based on this.
+-
+- As the functions described in the last sections already mention
+-separate sets of messages can be selected by a "domain name". This is a
+-simple string which should be unique for each program part with uses a
+-separate domain. It is possible to use in one program arbitrary many
+-domains at the same time. E.g., the GNU C Library itself uses a domain
+-named `libc' while the program using the C Library could use a domain
+-named `foo'. The important point is that at any time exactly one
+-domain is active. This is controlled with the following function.
+-
+- - Function: char * textdomain (const char *DOMAINNAME)
+- The `textdomain' function sets the default domain, which is used in
+- all future `gettext' calls, to DOMAINNAME. Please note that
+- `dgettext' and `dcgettext' calls are not influenced if the
+- DOMAINNAME parameter of these functions is not the null pointer.
+-
+- Before the first call to `textdomain' the default domain is
+- `messages'. This is the name specified in the specification of
+- the `gettext' API. This name is as good as any other name. No
+- program should ever really use a domain with this name since this
+- can only lead to problems.
+-
+- The function returns the value which is from now on taken as the
+- default domain. If the system went out of memory the returned
+- value is `NULL' and the global variable ERRNO is set to `ENOMEM'.
+- Despite the return value type being `char *' the return string must
+- not be changed. It is allocated internally by the `textdomain'
+- function.
+-
+- If the DOMAINNAME parameter is the null pointer no new default
+- domain is set. Instead the currently selected default domain is
+- returned.
+-
+- If the DOMAINNAME parameter is the empty string the default domain
+- is reset to its initial value, the domain with the name `messages'.
+- This possibility is questionable to use since the domain `messages'
+- really never should be used.
+-
+- - Function: char * bindtextdomain (const char *DOMAINNAME, const char
+- *DIRNAME)
+- The `bindtextdomain' function can be used to specify the directory
+- which contains the message catalogs for domain DOMAINNAME for the
+- different languages. To be correct, this is the directory where
+- the hierarchy of directories is expected. Details are explained
+- below.
+-
+- For the programmer it is important to note that the translations
+- which come with the program have be placed in a directory
+- hierarchy starting at, say, `/foo/bar'. Then the program should
+- make a `bindtextdomain' call to bind the domain for the current
+- program to this directory. So it is made sure the catalogs are
+- found. A correctly running program does not depend on the user
+- setting an environment variable.
+-
+- The `bindtextdomain' function can be used several times and if the
+- DOMAINNAME argument is different the previously bound domains will
+- not be overwritten.
+-
+- If the program which wish to use `bindtextdomain' at some point of
+- time use the `chdir' function to change the current working
+- directory it is important that the DIRNAME strings ought to be an
+- absolute pathname. Otherwise the addressed directory might vary
+- with the time.
+-
+- If the DIRNAME parameter is the null pointer `bindtextdomain'
+- returns the currently selected directory for the domain with the
+- name DOMAINNAME.
+-
+- The `bindtextdomain' function returns a pointer to a string
+- containing the name of the selected directory name. The string is
+- allocated internally in the function and must not be changed by the
+- user. If the system went out of core during the execution of
+- `bindtextdomain' the return value is `NULL' and the global
+- variable ERRNO is set accordingly.

+-Additional functions for more complicated situations
+-....................................................
+-
+- The functions of the `gettext' family described so far (and all the
+-`catgets' functions as well) have one problem in the real world which
+-have been neglected completely in all existing approaches. What is
+-meant here is the handling of plural forms.
+-
+- Looking through Unix source code before the time anybody thought
+-about internationalization (and, sadly, even afterwards) one can often
+-find code similar to the following:
+-
+- printf ("%d file%s deleted", n, n == 1 ? "" : "s");
+-
+-After the first complaints from people internationalizing the code
+-people either completely avoided formulations like this or used strings
+-like `"file(s)"'. Both look unnatural and should be avoided. First
+-tries to solve the problem correctly looked like this:
+-
+- if (n == 1)
+- printf ("%d file deleted", n);
+- else
+- printf ("%d files deleted", n);
+-
+- But this does not solve the problem. It helps languages where the
+-plural form of a noun is not simply constructed by adding an `s' but
+-that is all. Once again people fell into the trap of believing the
+-rules their language is using are universal. But the handling of plural
+-forms differs widely between the language families. There are two
+-things we can differ between (and even inside language families);
+-
+- * The form how plural forms are build differs. This is a problem
+- with language which have many irregularities. German, for
+- instance, is a drastic case. Though English and German are part
+- of the same language family (Germanic), the almost regular forming
+- of plural noun forms (appending an `s') is hardly found in German.
+-
+- * The number of plural forms differ. This is somewhat surprising for
+- those who only have experiences with Romanic and Germanic languages
+- since here the number is the same (there are two).
+-
+- But other language families have only one form or many forms. More
+- information on this in an extra section.
+-
+- The consequence of this is that application writers should not try to
+-solve the problem in their code. This would be localization since it is
+-only usable for certain, hardcoded language environments. Instead the
+-extended `gettext' interface should be used.
+-
+- These extra functions are taking instead of the one key string two
+-strings and an numerical argument. The idea behind this is that using
+-the numerical argument and the first string as a key, the implementation
+-can select using rules specified by the translator the right plural
+-form. The two string arguments then will be used to provide a return
+-value in case no message catalog is found (similar to the normal
+-`gettext' behavior). In this case the rules for Germanic language is
+-used and it is assumed that the first string argument is the singular
+-form, the second the plural form.
+-
+- This has the consequence that programs without language catalogs can
+-display the correct strings only if the program itself is written using
+-a Germanic language. This is a limitation but since the GNU C library
+-(as well as the GNU `gettext' package) are written as part of the GNU
+-package and the coding standards for the GNU project require program
+-being written in English, this solution nevertheless fulfills its
+-purpose.
+-
+- - Function: char * ngettext (const char *MSGID1, const char *MSGID2,
+- unsigned long int N)
+- The `ngettext' function is similar to the `gettext' function as it
+- finds the message catalogs in the same way. But it takes two
+- extra arguments. The MSGID1 parameter must contain the singular
+- form of the string to be converted. It is also used as the key
+- for the search in the catalog. The MSGID2 parameter is the plural
+- form. The parameter N is used to determine the plural form. If no
+- message catalog is found MSGID1 is returned if `n == 1', otherwise
+- `msgid2'.
+-
+- An example for the us of this function is:
+-
+- printf (ngettext ("%d file removed", "%d files removed", n), n);
+-
+- Please note that the numeric value N has to be passed to the
+- `printf' function as well. It is not sufficient to pass it only to
+- `ngettext'.
+-
+- - Function: char * dngettext (const char *DOMAIN, const char *MSGID1,
+- const char *MSGID2, unsigned long int N)
+- The `dngettext' is similar to the `dgettext' function in the way
+- the message catalog is selected. The difference is that it takes
+- two extra parameter to provide the correct plural form. These two
+- parameters are handled in the same way `ngettext' handles them.
+-
+- - Function: char * dcngettext (const char *DOMAIN, const char *MSGID1,
+- const char *MSGID2, unsigned long int N, int CATEGORY)
+- The `dcngettext' is similar to the `dcgettext' function in the way
+- the message catalog is selected. The difference is that it takes
+- two extra parameter to provide the correct plural form. These two
+- parameters are handled in the same way `ngettext' handles them.
+-
+-The problem of plural forms
+-...........................
+-
+- A description of the problem can be found at the beginning of the
+-last section. Now there is the question how to solve it. Without the
+-input of linguists (which was not available) it was not possible to
+-determine whether there are only a few different forms in which plural
+-forms are formed or whether the number can increase with every new
+-supported language.
+-
+- Therefore the solution implemented is to allow the translator to
+-specify the rules of how to select the plural form. Since the formula
+-varies with every language this is the only viable solution except for
+-hardcoding the information in the code (which still would require the
+-possibility of extensions to not prevent the use of new languages). The
+-details are explained in the GNU `gettext' manual. Here only a a bit
+-of information is provided.
+-
+- The information about the plural form selection has to be stored in
+-the header entry (the one with the empty (`msgid' string). It looks
+-like this:
+-
+- Plural-Forms: nplurals=2; plural=n == 1 ? 0 : 1;
+-
+- The `nplurals' value must be a decimal number which specifies how
+-many different plural forms exist for this language. The string
+-following `plural' is an expression which is using the C language
+-syntax. Exceptions are that no negative number are allowed, numbers
+-must be decimal, and the only variable allowed is `n'. This expression
+-will be evaluated whenever one of the functions `ngettext',
+-`dngettext', or `dcngettext' is called. The numeric value passed to
+-these functions is then substituted for all uses of the variable `n' in
+-the expression. The resulting value then must be greater or equal to
+-zero and smaller than the value given as the value of `nplurals'.
+-
+-The following rules are known at this point. The language with families
+-are listed. But this does not necessarily mean the information can be
+-generalized for the whole family (as can be easily seen in the table
+-below).(1)
+-
+-Only one form:
+- Some languages only require one single form. There is no
+- distinction between the singular and plural form. An appropriate
+- header entry would look like this:
+-
+- Plural-Forms: nplurals=1; plural=0;
+-
+- Languages with this property include:
+-
+- Finno-Ugric family
+- Hungarian
+-
+- Asian family
+- Japanese
+-
+- Turkic/Altaic family

+-
+-Two forms, singular used for one only

+- English is using. A header entry would look like this:

+- Plural-Forms: nplurals=2; plural=n != 1;
+-

+- expressions have to value zero or one.)

+-
+-How to specify the output character set `gettext' uses
+-......................................................
+-
+- `gettext' not only looks up a translation in a message catalog. It
+-also converts the translation on the fly to the desired output character
+-set. This is useful if the user is working in a different character set
+-than the translator who created the message catalog, because it avoids
+-distributing variants of message catalogs which differ only in the
+-character set.
+-
+- The output character set is, by default, the value of `nl_langinfo
+-(CODESET)', which depends on the `LC_CTYPE' part of the current locale.
+-But programs which store strings in a locale independent way (e.g.
+-UTF-8) can request that `gettext' and related functions return the
+-translations in that encoding, by use of the `bind_textdomain_codeset'
+-function.
+-
+- Note that the MSGID argument to `gettext' is not subject to
+-character set conversion. Also, when `gettext' does not find a
+-translation for MSGID, it returns MSGID unchanged - independently of
+-the current output character set. It is therefore recommended that all
+-MSGIDs be US-ASCII strings.
+-
+- - Function: char * bind_textdomain_codeset (const char *DOMAINNAME,
+- const char *CODESET)
+- The `bind_textdomain_codeset' function can be used to specify the
+- output character set for message catalogs for domain DOMAINNAME.
+- The CODESET argument must be a valid codeset name which can be used
+- for the `iconv_open' function, or a null pointer.
+-
+- If the CODESET parameter is the null pointer,
+- `bind_textdomain_codeset' returns the currently selected codeset
+- for the domain with the name DOMAINNAME. It returns `NULL' if no
+- codeset has yet been selected.
+-
+- The `bind_textdomain_codeset' function can be used several times.
+- If used multiple times with the same DOMAINNAME argument, the
+- later call overrides the settings made by the earlier one.
+-
+- The `bind_textdomain_codeset' function returns a pointer to a
+- string containing the name of the selected codeset. The string is
+- allocated internally in the function and must not be changed by the
+- user. If the system went out of core during the execution of
+- `bind_textdomain_codeset', the return value is `NULL' and the
+- global variable ERRNO is set accordingly.

+-
+-How to use `gettext' in GUI programs
+-....................................
+-
+- One place where the `gettext' functions, if used normally, have big
+-problems is within programs with graphical user interfaces (GUIs). The
+-problem is that many of the strings which have to be translated are very
+-short. They have to appear in pull-down menus which restricts the
+-length. But strings which are not containing entire sentences or at
+-least large fragments of a sentence may appear in more than one
+-situation in the program but might have different translations. This is
+-especially true for the one-word strings which are frequently used in
+-GUI programs.
+-
+- As a consequence many people say that the `gettext' approach is
+-wrong and instead `catgets' should be used which indeed does not have
+-this problem. But there is a very simple and powerful method to handle
+-these kind of problems with the `gettext' functions.
+-
+-As as example consider the following fictional situation. A GUI program
+-has a menu bar with the following entries:
+-
+- +------------+------------+--------------------------------------+
+- | File | Printer | |
+- +------------+------------+--------------------------------------+
+- | Open | | Select |
+- | New | | Open |
+- +----------+ | Connect |
+- +----------+
+-
+- To have the strings `File', `Printer', `Open', `New', `Select', and
+-`Connect' translated there has to be at some point in the code a call
+-to a function of the `gettext' family. But in two places the string
+-passed into the function would be `Open'. The translations might not
+-be the same and therefore we are in the dilemma described above.
+-
+- One solution to this problem is to artificially enlengthen the
+-strings to make them unambiguous. But what would the program do if no
+-translation is available? The enlengthened string is not what should be
+-printed. So we should use a little bit modified version of the
+-functions.
+-
+- To enlengthen the strings a uniform method should be used. E.g., in
+-the example above the strings could be chosen as
+-
+- Menu|File
+- Menu|Printer
+- Menu|File|Open
+- Menu|File|New
+- Menu|Printer|Select
+- Menu|Printer|Open
+- Menu|Printer|Connect
+-
+- Now all the strings are different and if now instead of `gettext'
+-the following little wrapper function is used, everything works just
+-fine:
+-
+- char *
+- sgettext (const char *msgid)
+- {
+- char *msgval = gettext (msgid);
+- if (msgval == msgid)
+- msgval = strrchr (msgid, '|') + 1;
+- return msgval;
+- }
+-
+- What this little function does is to recognize the case when no
+-translation is available. This can be done very efficiently by a
+-pointer comparison since the return value is the input value. If there
+-is no translation we know that the input string is in the format we used
+-for the Menu entries and therefore contains a `|' character. We simply
+-search for the last occurrence of this character and return a pointer
+-to the character following it. That's it!
+-
+- If one now consistently uses the enlengthened string form and
+-replaces the `gettext' calls with calls to `sgettext' (this is normally
+-limited to very few places in the GUI implementation) then it is
+-possible to produce a program which can be internationalized.
+-
+- With advanced compilers (such as GNU C) one can write the `sgettext'
+-functions as an inline function or as a macro like this:
+-
+- #define sgettext(msgid) \
+- ({ const char *__msgid = (msgid); \
+- char *__msgstr = gettext (__msgid); \
+- if (__msgval == __msgid) \
+- __msgval = strrchr (__msgid, '|') + 1; \
+- __msgval; })
+-
+- The other `gettext' functions (`dgettext', `dcgettext' and the
+-`ngettext' equivalents) can and should have corresponding functions as
+-well which look almost identical, except for the parameters and the
+-call to the underlying function.
+-
+- Now there is of course the question why such functions do not exist
+-in the GNU C library? There are two parts of the answer to this
+-question.
+-
+- * They are easy to write and therefore can be provided by the
+- project they are used in. This is not an answer by itself and
+- must be seen together with the second part which is:
+-
+- * There is no way the C library can contain a version which can work
+- everywhere. The problem is the selection of the character to
+- separate the prefix from the actual string in the enlenghtened
+- string. The examples above used `|' which is a quite good choice
+- because it resembles a notation frequently used in this context
+- and it also is a character not often used in message strings.
+-
+- But what if the character is used in message strings. Or if the
+- chose character is not available in the character set on the
+- machine one compiles (e.g., `|' is not required to exist for
+- ISO C; this is why the `iso646.h' file exists in ISO C programming
+- environments).
+-
+- There is only one more comment to make left. The wrapper function
+-above require that the translations strings are not enlengthened

+-
+-User influence on `gettext'
+-...........................
+-
+- The last sections described what the programmer can do to
+-internationalize the messages of the program. But it is finally up to
+-the user to select the message s/he wants to see. S/He must understand
+-them.
+-
+- The POSIX locale model uses the environment variables `LC_COLLATE',
+-`LC_CTYPE', `LC_MESSAGES', `LC_MONETARY', `NUMERIC', and `LC_TIME' to
+-select the locale which is to be used. This way the user can influence
+-lots of functions. As we mentioned above the `gettext' functions also
+-take advantage of this.
+-
+- To understand how this happens it is necessary to take a look at the
+-various components of the filename which gets computed to locate a
+-message catalog. It is composed as follows:
+-
+- DIR_NAME/LOCALE/LC_CATEGORY/DOMAIN_NAME.mo
+-
+- The default value for DIR_NAME is system specific. It is computed
+-from the value given as the prefix while configuring the C library.
+-This value normally is `/usr' or `/'. For the former the complete
+-DIR_NAME is:
+-
+- /usr/share/locale
+-
+- We can use `/usr/share' since the `.mo' files containing the message
+-catalogs are system independent, so all systems can use the same files.
+-If the program executed the `bindtextdomain' function for the message
+-domain that is currently handled, the `dir_name' component is exactly
+-the value which was given to the function as the second parameter.
+-I.e., `bindtextdomain' allows overwriting the only system dependent and
+-fixed value to make it possible to address files anywhere in the
+-filesystem.
+-
+- The CATEGORY is the name of the locale category which was selected
+-in the program code. For `gettext' and `dgettext' this is always
+-`LC_MESSAGES', for `dcgettext' this is selected by the value of the
+-third parameter. As said above it should be avoided to ever use a
+-category other than `LC_MESSAGES'.
+-
+- The LOCALE component is computed based on the category used. Just
+-like for the `setlocale' function here comes the user selection into
+-the play. Some environment variables are examined in a fixed order and
+-the first environment variable set determines the return value of the
+-lookup process. In detail, for the category `LC_xxx' the following
+-variables in this order are examined:
+-
+-`LANGUAGE'
+-
+-`LC_ALL'
+-
+-`LC_xxx'
+-
+-`LANG'
+- This looks very familiar. With the exception of the `LANGUAGE'
+-environment variable this is exactly the lookup order the `setlocale'
+-function uses. But why introducing the `LANGUAGE' variable?
+-
+- The reason is that the syntax of the values these variables can have
+-is different to what is expected by the `setlocale' function. If we
+-would set `LC_ALL' to a value following the extended syntax that would
+-mean the `setlocale' function will never be able to use the value of
+-this variable as well. An additional variable removes this problem
+-plus we can select the language independently of the locale setting
+-which sometimes is useful.
+-
+- While for the `LC_xxx' variables the value should consist of exactly
+-one specification of a locale the `LANGUAGE' variable's value can
+-consist of a colon separated list of locale names. The attentive
+-reader will realize that this is the way we manage to implement one of
+-our additional demands above: we want to be able to specify an ordered
+-list of language.
+-
+- Back to the constructed filename we have only one component missing.
+-The DOMAIN_NAME part is the name which was either registered using the
+-`textdomain' function or which was given to `dgettext' or `dcgettext'
+-as the first parameter. Now it becomes obvious that a good choice for
+-the domain name in the program code is a string which is closely
+-related to the program/package name. E.g., for the GNU C Library the
+-domain name is `libc'.
+-
+-A limit piece of example code should show how the programmer is supposed
+-to work:
+-
+- {
+- setlocale (LC_ALL, "");
+- textdomain ("test-package");
+- bindtextdomain ("test-package", "/usr/local/share/locale");
+- puts (gettext ("Hello, world!"));
+- }
+-
+- At the program start the default domain is `messages', and the
+-default locale is "C". The `setlocale' call sets the locale according
+-to the user's environment variables; remember that correct functioning
+-of `gettext' relies on the correct setting of the `LC_MESSAGES' locale
+-(for looking up the message catalog) and of the `LC_CTYPE' locale (for
+-the character set conversion). The `textdomain' call changes the
+-default domain to `test-package'. The `bindtextdomain' call specifies
+-that the message catalogs for the domain `test-package' can be found
+-below the directory `/usr/local/share/locale'.
+-
+- If now the user set in her/his environment the variable `LANGUAGE'
+-to `de' the `gettext' function will try to use the translations from
+-the file
+-
+- /usr/local/share/locale/de/LC_MESSAGES/test-package.mo
+-
+- From the above descriptions it should be clear which component of
+-this filename is determined by which source.
+-
+- In the above example we assumed that the `LANGUAGE' environment
+-variable to `de'. This might be an appropriate selection but what
+-happens if the user wants to use `LC_ALL' because of the wider
+-usability and here the required value is `de_DE.ISO-8859-1'? We
+-already mentioned above that a situation like this is not infrequent.
+-E.g., a person might prefer reading a dialect and if this is not
+-available fall back on the standard language.
+-
+- The `gettext' functions know about situations like this and can
+-handle them gracefully. The functions recognize the format of the value
+-of the environment variable. It can split the value is different pieces
+-and by leaving out the only or the other part it can construct new
+-values. This happens of course in a predictable way. To understand
+-this one must know the format of the environment variable value. There
+-is one more or less standardized form, originally from the X/Open
+-specification:
+-
+- `language[_territory[.codeset]][@modifier]'
+-
+- Less specific locale names will be stripped of in the order of the
+-following list:
+-
+- 1. `codeset'
+-
+- 2. `normalized codeset'
+-
+- 3. `territory'
+-
+- 4. `modifier'
+-
+- The `language' field will never be dropped for obvious reasons.
+-
+- The only new thing is the `normalized codeset' entry. This is
+-another goodie which is introduced to help reducing the chaos which
+-derives from the inability of the people to standardize the names of
+-character sets. Instead of ISO-8859-1 one can often see 8859-1, 88591,
+-iso8859-1, or iso_8859-1. The `normalized codeset' value is generated
+-from the user-provided character set name by applying the following
+-rules:
+-
+- 1. Remove all characters beside numbers and letters.
+-
+- 2. Fold letters to lowercase.
+-
+- 3. If the same only contains digits prepend the string `"iso"'.
+-
+-So all of the above name will be normalized to `iso88591'. This allows
+-the program user much more freely choosing the locale name.
+-
+- Even this extended functionality still does not help to solve the
+-problem that completely different names can be used to denote the same
+-locale (e.g., `de' and `german'). To be of help in this situation the
+-locale implementation and also the `gettext' functions know about
+-aliases.
+-
+- The file `/usr/share/locale/locale.alias' (replace `/usr' with
+-whatever prefix you used for configuring the C library) contains a
+-mapping of alternative names to more regular names. The system manager
+-is free to add new entries to fill her/his own needs. The selected
+-locale from the environment is compared with the entries in the first
+-column of this file ignoring the case. If they match the value of the
+-second column is used instead for the further handling.
+-
+- In the description of the format of the environment variables we
+-already mentioned the character set as a factor in the selection of the
+-message catalog. In fact, only catalogs which contain text written
+-using the character set of the system/program can be used (directly;
+-there will come a solution for this some day). This means for the user
+-that s/he will always have to take care for this. If in the collection
+-of the message catalogs there are files for the same language but coded
+-using different character sets the user has to be careful.

+-Programs to handle message catalogs for `gettext'
+--------------------------------------------------
+-
+- The GNU C Library does not contain the source code for the programs
+-to handle message catalogs for the `gettext' functions. As part of the
+-GNU project the GNU gettext package contains everything the developer
+-needs. The functionality provided by the tools in this package by far
+-exceeds the abilities of the `gencat' program described above for the
+-`catgets' functions.
+-
+- There is a program `msgfmt' which is the equivalent program to the
+-`gencat' program. It generates from the human-readable and -editable
+-form of the message catalog a binary file which can be used by the
+-`gettext' functions. But there are several more programs available.
+-
+- The `xgettext' program can be used to automatically extract the
+-translatable messages from a source file. I.e., the programmer need not
+-take care for the translations and the list of messages which have to be
+-translated. S/He will simply wrap the translatable string in calls to
+-`gettext' et.al and the rest will be done by `xgettext'. This program
+-has a lot of option which help to customize the output or do help to
+-understand the input better.
+-
+- Other programs help to manage development cycle when new messages
+-appear in the source files or when a new translation of the messages
+-appear. here it should only be noted that using all the tools in GNU
+-gettext it is possible to _completely_ automize the handling of message
+-catalog. Beside marking the translatable string in the source code and
+-generating the translations the developers do not have anything to do

+-
+-Defining the Comparison Function
+-================================
+-
+- In order to use the sorted array library functions, you have to
+-describe how to compare the elements of the array.
+-
+- To do this, you supply a comparison function to compare two elements
+-of the array. The library will call this function, passing as arguments
+-pointers to two array elements to be compared. Your comparison function
+-should return a value the way `strcmp' (*note String/Array
+-Comparison::) does: negative if the first argument is "less" than the
+-second, zero if they are "equal", and positive if the first argument is
+-"greater".
+-
+- Here is an example of a comparison function which works with an
+-array of numbers of type `double':
+-
+- int
+- compare_doubles (const void *a, const void *b)
+- {
+- const double *da = (const double *) a;
+- const double *db = (const double *) b;
+-
+- return (*da > *db) - (*da < *db);
+- }
+-
+- The header file `stdlib.h' defines a name for the data type of
+-comparison functions. This type is a GNU extension.
+-
+- int comparison_fn_t (const void *, const void *);

+-
+-Array Search Function
+-=====================
+-
+- Generally searching for a specific element in an array means that
+-potentially all elements must be checked. The GNU C library contains
+-functions to perform linear search. The prototypes for the following
+-two functions can be found in `search.h'.
+-
+- - Function: void * lfind (const void *KEY, void *BASE, size_t *NMEMB,
+- size_t SIZE, comparison_fn_t COMPAR)
+- The `lfind' function searches in the array with `*NMEMB' elements
+- of SIZE bytes pointed to by BASE for an element which matches the
+- one pointed to by KEY. The function pointed to by COMPAR is used
+- decide whether two elements match.
+-
+- The return value is a pointer to the matching element in the array
+- starting at BASE if it is found. If no matching element is
+- available `NULL' is returned.
+-
+- The mean runtime of this function is `*NMEMB'/2. This function
+- should only be used elements often get added to or deleted from
+- the array in which case it might not be useful to sort the array
+- before searching.
+-
+- - Function: void * lsearch (const void *KEY, void *BASE, size_t
+- *NMEMB, size_t SIZE, comparison_fn_t COMPAR)
+- The `lsearch' function is similar to the `lfind' function. It
+- searches the given array for an element and returns it if found.
+- The difference is that if no matching element is found the
+- `lsearch' function adds the object pointed to by KEY (with a size
+- of SIZE bytes) at the end of the array and it increments the value
+- of `*NMEMB' to reflect this addition.
+-
+- This means for the caller that if it is not sure that the array
+- contains the element one is searching for the memory allocated for
+- the array starting at BASE must have room for at least SIZE more
+- bytes. If one is sure the element is in the array it is better to
+- use `lfind' so having more room in the array is always necessary
+- when calling `lsearch'.
+-
+- To search a sorted array for an element matching the key, use the
+-`bsearch' function. The prototype for this function is in the header
+-file `stdlib.h'.
+-
+- - Function: void * bsearch (const void *KEY, const void *ARRAY, size_t
+- COUNT, size_t SIZE, comparison_fn_t COMPARE)
+- The `bsearch' function searches the sorted array ARRAY for an
+- object that is equivalent to KEY. The array contains COUNT
+- elements, each of which is of size SIZE bytes.
+-
+- The COMPARE function is used to perform the comparison. This
+- function is called with two pointer arguments and should return an
+- integer less than, equal to, or greater than zero corresponding to
+- whether its first argument is considered less than, equal to, or
+- greater than its second argument. The elements of the ARRAY must
+- already be sorted in ascending order according to this comparison
+- function.
+-
+- The return value is a pointer to the matching array element, or a
+- null pointer if no match is found. If the array contains more
+- than one element that matches, the one that is returned is
+- unspecified.
+-
+- This function derives its name from the fact that it is implemented
+- using the binary search algorithm.
+-
+-\1f
+-File: libc.info, Node: Array Sort Function, Next: Search/Sort Example, Prev: Array Search Function, Up: Searching and Sorting
+-
+-Array Sort Function
+-===================
+-
+- To sort an array using an arbitrary comparison function, use the
+-`qsort' function. The prototype for this function is in `stdlib.h'.
+-
+- - Function: void qsort (void *ARRAY, size_t COUNT, size_t SIZE,
+- comparison_fn_t COMPARE)
+- The QSORT function sorts the array ARRAY. The array contains
+- COUNT elements, each of which is of size SIZE.
+-
+- The COMPARE function is used to perform the comparison on the
+- array elements. This function is called with two pointer
+- arguments and should return an integer less than, equal to, or
+- greater than zero corresponding to whether its first argument is
+- considered less than, equal to, or greater than its second
+- argument.
+-
+- *Warning:* If two objects compare as equal, their order after
+- sorting is unpredictable. That is to say, the sorting is not
+- stable. This can make a difference when the comparison considers
+- only part of the elements. Two elements with the same sort key
+- may differ in other respects.
+-
+- If you want the effect of a stable sort, you can get this result by
+- writing the comparison function so that, lacking other reason
+- distinguish between two elements, it compares them by their
+- addresses. Note that doing this may make the sorting algorithm
+- less efficient, so do it only if necessary.
+-
+- Here is a simple example of sorting an array of doubles in
+- numerical order, using the comparison function defined above
+- (*note Comparison Functions::):
+-
+- {
+- double *array;
+- int size;
+- ...
+- qsort (array, size, sizeof (double), compare_doubles);
+- }
+-
+- The `qsort' function derives its name from the fact that it was
+- originally implemented using the "quick sort" algorithm.
+-
+- The implementation of `qsort' in this library might not be an
+- in-place sort and might thereby use an extra amount of memory to
+- store the array.

+-=============================

+- Here is an example showing the use of `qsort' and `bsearch' with an

+-their `name' fields with the `strcmp' function. Then, we can look up

+-
+-The `hsearch' function.
+-=======================
+-
+- The functions mentioned so far in this chapter are searching in a
+-sorted or unsorted array. There are other methods to organize
+-information which later should be searched. The costs of insert,
+-delete and search differ. One possible implementation is using hashing
+-tables. The following functions are declared in the the header file
+-`search.h'.
+-
+- - Function: int hcreate (size_t NEL)
+- The `hcreate' function creates a hashing table which can contain at
+- least NEL elements. There is no possibility to grow this table so
+- it is necessary to choose the value for NEL wisely. The used
+- methods to implement this function might make it necessary to make
+- the number of elements in the hashing table larger than the
+- expected maximal number of elements. Hashing tables usually work
+- inefficient if they are filled 80% or more. The constant access
+- time guaranteed by hashing can only be achieved if few collisions
+- exist. See Knuth's "The Art of Computer Programming, Part 3:
+- Searching and Sorting" for more information.
+-
+- The weakest aspect of this function is that there can be at most
+- one hashing table used through the whole program. The table is
+- allocated in local memory out of control of the programmer. As an
+- extension the GNU C library provides an additional set of
+- functions with an reentrant interface which provide a similar
+- interface but which allow to keep arbitrarily many hashing tables.
+-
+- It is possible to use more than one hashing table in the program
+- run if the former table is first destroyed by a call to `hdestroy'.
+-
+- The function returns a non-zero value if successful. If it return
+- zero something went wrong. This could either mean there is
+- already a hashing table in use or the program runs out of memory.
+-
+- - Function: void hdestroy (void)
+- The `hdestroy' function can be used to free all the resources
+- allocated in a previous call of `hcreate'. After a call to this
+- function it is again possible to call `hcreate' and allocate a new
+- table with possibly different size.
+-
+- It is important to remember that the elements contained in the
+- hashing table at the time `hdestroy' is called are _not_ freed by
+- this function. It is the responsibility of the program code to
+- free those strings (if necessary at all). Freeing all the element
+- memory is not possible without extra, separately kept information
+- since there is no function to iterate through all available
+- elements in the hashing table. If it is really necessary to free
+- a table and all elements the programmer has to keep a list of all
+- table elements and before calling `hdestroy' s/he has to free all
+- element's data using this list. This is a very unpleasant
+- mechanism and it also shows that this kind of hashing tables is
+- mainly meant for tables which are created once and used until the
+- end of the program run.
+-
+- Entries of the hashing table and keys for the search are defined
+-using this type:
+-
+- - Data type: struct ENTRY
+- Both elements of this structure are pointers to zero-terminated
+- strings. This is a limiting restriction of the functionality of
+- the `hsearch' functions. They can only be used for data sets
+- which use the NUL character always and solely to terminate the
+- records. It is not possible to handle general binary data.
+-
+- `char *key'
+- Pointer to a zero-terminated string of characters describing
+- the key for the search or the element in the hashing table.
+-
+- `char *data'
+- Pointer to a zero-terminated string of characters describing
+- the data. If the functions will be called only for searching
+- an existing entry this element might stay undefined since it
+- is not used.
+-
+- - Function: ENTRY * hsearch (ENTRY ITEM, ACTION ACTION)
+- To search in a hashing table created using `hcreate' the `hsearch'
+- function must be used. This function can perform simple search
+- for an element (if ACTION has the `FIND') or it can alternatively
+- insert the key element into the hashing table. Entries are never
+- replaced.
+-
+- The key is denoted by a pointer to an object of type `ENTRY'. For
+- locating the corresponding position in the hashing table only the
+- `key' element of the structure is used.
+-
+- If an entry with matching key is found the ACTION parameter is
+- irrelevant. The found entry is returned. If no matching entry is
+- found and the ACTION parameter has the value `FIND' the function
+- returns a `NULL' pointer. If no entry is found and the ACTION
+- parameter has the value `ENTER' a new entry is added to the
+- hashing table which is initialized with the parameter ITEM. A
+- pointer to the newly added entry is returned.
+-
+- As mentioned before the hashing table used by the functions
+-described so far is global and there can be at any time at most one
+-hashing table in the program. A solution is to use the following
+-functions which are a GNU extension. All have in common that they
+-operate on a hashing table which is described by the content of an
+-object of the type `struct hsearch_data'. This type should be treated
+-as opaque, none of its members should be changed directly.
+-
+- - Function: int hcreate_r (size_t NEL, struct hsearch_data *HTAB)
+- The `hcreate_r' function initializes the object pointed to by HTAB
+- to contain a hashing table with at least NEL elements. So this
+- function is equivalent to the `hcreate' function except that the
+- initialized data structure is controlled by the user.
+-
+- This allows having more than one hashing table at one time. The
+- memory necessary for the `struct hsearch_data' object can be
+- allocated dynamically. It must be initialized with zero before
+- calling this function.
+-
+- The return value is non-zero if the operation were successful. if
+- the return value is zero something went wrong which probably means
+- the programs runs out of memory.
+-
+- - Function: void hdestroy_r (struct hsearch_data *HTAB)
+- The `hdestroy_r' function frees all resources allocated by the
+- `hcreate_r' function for this very same object HTAB. As for
+- `hdestroy' it is the programs responsibility to free the strings
+- for the elements of the table.
+-
+- - Function: int hsearch_r (ENTRY ITEM, ACTION ACTION, ENTRY **RETVAL,
+- struct hsearch_data *HTAB)
+- The `hsearch_r' function is equivalent to `hsearch'. The meaning
+- of the first two arguments is identical. But instead of operating
+- on a single global hashing table the function works on the table
+- described by the object pointed to by HTAB (which is initialized
+- by a call to `hcreate_r').
+-
+- Another difference to `hcreate' is that the pointer to the found
+- entry in the table is not the return value of the functions. It is
+- returned by storing it in a pointer variables pointed to by the
+- RETVAL parameter. The return value of the function is an integer
+- value indicating success if it is non-zero and failure if it is
+- zero. In the latter case the global variable ERRNO signals the
+- reason for the failure.
+-
+- `ENOMEM'
+- The table is filled and `hsearch_r' was called with an so far
+- unknown key and ACTION set to `ENTER'.
+-
+- `ESRCH'
+- The ACTION parameter is `FIND' and no corresponding element
+- is found in the table.

+-
+-The `tsearch' function.
+-=======================
+-
+- Another common form to organize data for efficient search is to use
+-trees. The `tsearch' function family provides a nice interface to
+-functions to organize possibly large amounts of data by providing a mean
+-access time proportional to the logarithm of the number of elements.
+-The GNU C library implementation even guarantees that this bound is
+-never exceeded even for input data which cause problems for simple
+-binary tree implementations.
+-
+- The functions described in the chapter are all described in the
+-System V and X/Open specifications and are therefore quite portable.
+-
+- In contrast to the `hsearch' functions the `tsearch' functions can
+-be used with arbitrary data and not only zero-terminated strings.
+-
+- The `tsearch' functions have the advantage that no function to
+-initialize data structures is necessary. A simple pointer of type
+-`void *' initialized to `NULL' is a valid tree and can be extended or
+-searched. The prototypes for these functions can be found in the
+-header file `search.h'.
+-
+- - Function: void * tsearch (const void *KEY, void **ROOTP,
+- comparison_fn_t COMPAR)
+- The `tsearch' function searches in the tree pointed to by `*ROOTP'
+- for an element matching KEY. The function pointed to by COMPAR is
+- used to determine whether two elements match. *Note Comparison
+- Functions::, for a specification of the functions which can be
+- used for the COMPAR parameter.
+-
+- If the tree does not contain a matching entry the KEY value will
+- be added to the tree. `tsearch' does not make a copy of the object
+- pointed to by KEY (how could it since the size is unknown).
+- Instead it adds a reference to this object which means the object
+- must be available as long as the tree data structure is used.
+-
+- The tree is represented by a pointer to a pointer since it is
+- sometimes necessary to change the root node of the tree. So it
+- must not be assumed that the variable pointed to by ROOTP has the
+- same value after the call. This also shows that it is not safe to
+- call the `tsearch' function more than once at the same time using
+- the same tree. It is no problem to run it more than once at a
+- time on different trees.
+-
+- The return value is a pointer to the matching element in the tree.
+- If a new element was created the pointer points to the new data
+- (which is in fact KEY). If an entry had to be created and the
+- program ran out of space `NULL' is returned.
+-
+- - Function: void * tfind (const void *KEY, void *const *ROOTP,
+- comparison_fn_t COMPAR)
+- The `tfind' function is similar to the `tsearch' function. It
+- locates an element matching the one pointed to by KEY and returns
+- a pointer to this element. But if no matching element is
+- available no new element is entered (note that the ROOTP parameter
+- points to a constant pointer). Instead the function returns
+- `NULL'.
+-
+- Another advantage of the `tsearch' function in contrast to the
+-`hsearch' functions is that there is an easy way to remove elements.
+-
+- - Function: void * tdelete (const void *KEY, void **ROOTP,
+- comparison_fn_t COMPAR)
+- To remove a specific element matching KEY from the tree `tdelete'
+- can be used. It locates the matching element using the same
+- method as `tfind'. The corresponding element is then removed and
+- a pointer to the parent of the deleted node is returned by the
+- function. If there is no matching entry in the tree nothing can be
+- deleted and the function returns `NULL'. If the root of the tree
+- is deleted `tdelete' returns some unspecified value not equal to
+- `NULL'.
+-
+- - Function: void tdestroy (void *VROOT, __free_fn_t FREEFCT)
+- If the complete search tree has to be removed one can use
+- `tdestroy'. It frees all resources allocated by the `tsearch'
+- function to generate the tree pointed to by VROOT.
+-
+- For the data in each tree node the function FREEFCT is called.
+- The pointer to the data is passed as the argument to the function.
+- If no such work is necessary FREEFCT must point to a function
+- doing nothing. It is called in any case.
+-
+- This function is a GNU extension and not covered by the System V or
+- X/Open specifications.
+-
+- In addition to the function to create and destroy the tree data
+-structure, there is another function which allows you to apply a
+-function to all elements of the tree. The function must have this type:
+-
+- void __action_fn_t (const void *nodep, VISIT value, int level);
+-
+- The NODEP is the data value of the current node (once given as the
+-KEY argument to `tsearch'). LEVEL is a numeric value which corresponds
+-to the depth of the current node in the tree. The root node has the
+-depth 0 and its children have a depth of 1 and so on. The `VISIT' type
+-is an enumeration type.
+-
+- - Data Type: VISIT
+- The `VISIT' value indicates the status of the current node in the
+- tree and how the function is called. The status of a node is
+- either `leaf' or `internal node'. For each leaf node the function
+- is called exactly once, for each internal node it is called three
+- times: before the first child is processed, after the first child
+- is processed and after both children are processed. This makes it
+- possible to handle all three methods of tree traversal (or even a
+- combination of them).
+-
+- `preorder'
+- The current node is an internal node and the function is
+- called before the first child was processed.
+-
+- `postorder'
+- The current node is an internal node and the function is
+- called after the first child was processed.
+-
+- `endorder'
+- The current node is an internal node and the function is
+- called after the second child was processed.
+-
+- `leaf'
+- The current node is a leaf.
+-
+- - Function: void twalk (const void *ROOT, __action_fn_t ACTION)
+- For each node in the tree with a node pointed to by ROOT, the
+- `twalk' function calls the function provided by the parameter
+- ACTION. For leaf nodes the function is called exactly once with
+- VALUE set to `leaf'. For internal nodes the function is called
+- three times, setting the VALUE parameter or ACTION to the
+- appropriate value. The LEVEL argument for the ACTION function is
+- computed while descending the tree with increasing the value by
+- one for the descend to a child, starting with the value 0 for the
+- root node.
+-
+- Since the functions used for the ACTION parameter to `twalk' must
+- not modify the tree data, it is safe to run `twalk' in more than
+- one thread at the same time, working on the same tree. It is also
+- safe to call `tfind' in parallel. Functions which modify the tree
+- must not be used, otherwise the behavior is undefined.

+-Pattern Matching
+-****************
+-
+- The GNU C Library provides pattern matching facilities for two kinds
+-of patterns: regular expressions and file-name wildcards. The library
+-also provides a facility for expanding variable and command references
+-and parsing text into words in the way the shell does.
+-
+-* Menu:
+-
+-* Wildcard Matching:: Matching a wildcard pattern against a single string.
+-* Globbing:: Finding the files that match a wildcard pattern.
+-* Regular Expressions:: Matching regular expressions against strings.
+-* Word Expansion:: Expanding shell variables, nested commands,
+- arithmetic, and wildcards.
+- This is what the shell does with shell commands.

+-
+-Wildcard Matching
+-=================
+-
+- This section describes how to match a wildcard pattern against a
+-particular string. The result is a yes or no answer: does the string
+-fit the pattern or not. The symbols described here are all declared in
+-`fnmatch.h'.
+-
+- - Function: int fnmatch (const char *PATTERN, const char *STRING, int
+- FLAGS)
+- This function tests whether the string STRING matches the pattern
+- PATTERN. It returns `0' if they do match; otherwise, it returns
+- the nonzero value `FNM_NOMATCH'. The arguments PATTERN and STRING
+- are both strings.
+-
+- The argument FLAGS is a combination of flag bits that alter the
+- details of matching. See below for a list of the defined flags.
+-
+- In the GNU C Library, `fnmatch' cannot experience an "error"--it
+- always returns an answer for whether the match succeeds. However,
+- other implementations of `fnmatch' might sometimes report "errors".
+- They would do so by returning nonzero values that are not equal to
+- `FNM_NOMATCH'.
+-
+- These are the available flags for the FLAGS argument:
+-
+-`FNM_FILE_NAME'
+- Treat the `/' character specially, for matching file names. If
+- this flag is set, wildcard constructs in PATTERN cannot match `/'
+- in STRING. Thus, the only way to match `/' is with an explicit
+- `/' in PATTERN.
+-
+-`FNM_PATHNAME'
+- This is an alias for `FNM_FILE_NAME'; it comes from POSIX.2. We
+- don't recommend this name because we don't use the term "pathname"
+- for file names.
+-
+-`FNM_PERIOD'
+- Treat the `.' character specially if it appears at the beginning of
+- STRING. If this flag is set, wildcard constructs in PATTERN
+- cannot match `.' as the first character of STRING.
+-
+- If you set both `FNM_PERIOD' and `FNM_FILE_NAME', then the special
+- treatment applies to `.' following `/' as well as to `.' at the
+- beginning of STRING. (The shell uses the `FNM_PERIOD' and
+- `FNM_FILE_NAME' flags together for matching file names.)
+-
+-`FNM_NOESCAPE'
+- Don't treat the `\' character specially in patterns. Normally,
+- `\' quotes the following character, turning off its special meaning
+- (if any) so that it matches only itself. When quoting is enabled,
+- the pattern `\?' matches only the string `?', because the question
+- mark in the pattern acts like an ordinary character.
+-
+- If you use `FNM_NOESCAPE', then `\' is an ordinary character.
+-
+-`FNM_LEADING_DIR'
+- Ignore a trailing sequence of characters starting with a `/' in
+- STRING; that is to say, test whether STRING starts with a
+- directory name that PATTERN matches.
+-
+- If this flag is set, either `foo*' or `foobar' as a pattern would
+- match the string `foobar/frobozz'.
+-
+-`FNM_CASEFOLD'
+- Ignore case in comparing STRING to PATTERN.
+-
+-`FNM_EXTMATCH'
+- Recognize beside the normal patterns also the extended patterns
+- introduced in `ksh'. The patterns are written in the form
+- explained in the following table where PATTERN-LIST is a `|'
+- separated list of patterns.
+-
+- `?(PATTERN-LIST)'
+- The pattern matches if zero or one occurrences of any of the
+- patterns in the PATTERN-LIST allow matching the input string.
+-
+- `*(PATTERN-LIST)'
+- The pattern matches if zero or more occurrences of any of the
+- patterns in the PATTERN-LIST allow matching the input string.
+-
+- `+(PATTERN-LIST)'
+- The pattern matches if one or more occurrences of any of the
+- patterns in the PATTERN-LIST allow matching the input string.
+-
+- `@(PATTERN-LIST)'
+- The pattern matches if exactly one occurrence of any of the
+- patterns in the PATTERN-LIST allows matching the input string.
+-
+- `!(PATTERN-LIST)'
+- The pattern matches if the input string cannot be matched
+- with any of the patterns in the PATTERN-LIST.

+-Globbing
+-========
+-
+- The archetypal use of wildcards is for matching against the files in
+-a directory, and making a list of all the matches. This is called
+-"globbing".
+-
+- You could do this using `fnmatch', by reading the directory entries
+-one by one and testing each one with `fnmatch'. But that would be slow
+-(and complex, since you would have to handle subdirectories by hand).
+-
+- The library provides a function `glob' to make this particular use
+-of wildcards convenient. `glob' and the other symbols in this section
+-are declared in `glob.h'.
+-
+-* Menu:
+-
+-* Calling Glob:: Basic use of `glob'.
+-* Flags for Globbing:: Flags that enable various options in `glob'.
+-* More Flags for Globbing:: GNU specific extensions to `glob'.

+-
+-Calling `glob'
+---------------
+-
+- The result of globbing is a vector of file names (strings). To
+-return this vector, `glob' uses a special data type, `glob_t', which is
+-a structure. You pass `glob' the address of the structure, and it
+-fills in the structure's fields to tell you about the results.
+-
+- - Data Type: glob_t
+- This data type holds a pointer to a word vector. More precisely,
+- it records both the address of the word vector and its size. The
+- GNU implementation contains some more fields which are non-standard
+- extensions.
+-
+- `gl_pathc'
+- The number of elements in the vector, excluding the initial
+- null entries if the GLOB_DOOFFS flag is used (see gl_offs
+- below).
+-
+- `gl_pathv'
+- The address of the vector. This field has type `char **'.
+-
+- `gl_offs'
+- The offset of the first real element of the vector, from its
+- nominal address in the `gl_pathv' field. Unlike the other
+- fields, this is always an input to `glob', rather than an
+- output from it.
+-
+- If you use a nonzero offset, then that many elements at the
+- beginning of the vector are left empty. (The `glob' function
+- fills them with null pointers.)
+-
+- The `gl_offs' field is meaningful only if you use the
+- `GLOB_DOOFFS' flag. Otherwise, the offset is always zero
+- regardless of what is in this field, and the first real
+- element comes at the beginning of the vector.
+-
+- `gl_closedir'
+- The address of an alternative implementation of the `closedir'
+- function. It is used if the `GLOB_ALTDIRFUNC' bit is set in
+- the flag parameter. The type of this field is
+- `void (*) (void *)'.
+-
+- This is a GNU extension.
+-
+- `gl_readdir'
+- The address of an alternative implementation of the `readdir'
+- function used to read the contents of a directory. It is
+- used if the `GLOB_ALTDIRFUNC' bit is set in the flag
+- parameter. The type of this field is
+- `struct dirent *(*) (void *)'.
+-
+- This is a GNU extension.
+-
+- `gl_opendir'
+- The address of an alternative implementation of the `opendir'
+- function. It is used if the `GLOB_ALTDIRFUNC' bit is set in
+- the flag parameter. The type of this field is
+- `void *(*) (const char *)'.
+-
+- This is a GNU extension.
+-
+- `gl_stat'
+- The address of an alternative implementation of the `stat'
+- function to get information about an object in the
+- filesystem. It is used if the `GLOB_ALTDIRFUNC' bit is set
+- in the flag parameter. The type of this field is
+- `int (*) (const char *, struct stat *)'.
+-
+- This is a GNU extension.
+-
+- `gl_lstat'
+- The address of an alternative implementation of the `lstat'
+- function to get information about an object in the
+- filesystems, not following symbolic links. It is used if the
+- `GLOB_ALTDIRFUNC' bit is set in the flag parameter. The type
+- of this field is `int (*) (const char *, struct stat *)'.
+-
+- This is a GNU extension.
+-
+- For use in the `glob64' function `glob.h' contains another
+-definition for a very similar type. `glob64_t' differs from `glob_t'
+-only in the types of the members `gl_readdir', `gl_stat', and
+-`gl_lstat'.
+-
+- - Data Type: glob64_t
+- This data type holds a pointer to a word vector. More precisely,
+- it records both the address of the word vector and its size. The
+- GNU implementation contains some more fields which are non-standard
+- extensions.
+-
+- `gl_pathc'
+- The number of elements in the vector, excluding the initial
+- null entries if the GLOB_DOOFFS flag is used (see gl_offs
+- below).
+-
+- `gl_pathv'
+- The address of the vector. This field has type `char **'.
+-
+- `gl_offs'
+- The offset of the first real element of the vector, from its
+- nominal address in the `gl_pathv' field. Unlike the other
+- fields, this is always an input to `glob', rather than an
+- output from it.
+-
+- If you use a nonzero offset, then that many elements at the
+- beginning of the vector are left empty. (The `glob' function
+- fills them with null pointers.)
+-
+- The `gl_offs' field is meaningful only if you use the
+- `GLOB_DOOFFS' flag. Otherwise, the offset is always zero
+- regardless of what is in this field, and the first real
+- element comes at the beginning of the vector.
+-
+- `gl_closedir'
+- The address of an alternative implementation of the `closedir'
+- function. It is used if the `GLOB_ALTDIRFUNC' bit is set in
+- the flag parameter. The type of this field is
+- `void (*) (void *)'.
+-
+- This is a GNU extension.
+-
+- `gl_readdir'
+- The address of an alternative implementation of the
+- `readdir64' function used to read the contents of a
+- directory. It is used if the `GLOB_ALTDIRFUNC' bit is set in
+- the flag parameter. The type of this field is
+- `struct dirent64 *(*) (void *)'.
+-
+- This is a GNU extension.
+-
+- `gl_opendir'
+- The address of an alternative implementation of the `opendir'
+- function. It is used if the `GLOB_ALTDIRFUNC' bit is set in
+- the flag parameter. The type of this field is
+- `void *(*) (const char *)'.
+-
+- This is a GNU extension.
+-
+- `gl_stat'
+- The address of an alternative implementation of the `stat64'
+- function to get information about an object in the
+- filesystem. It is used if the `GLOB_ALTDIRFUNC' bit is set
+- in the flag parameter. The type of this field is
+- `int (*) (const char *, struct stat64 *)'.
+-
+- This is a GNU extension.
+-
+- `gl_lstat'
+- The address of an alternative implementation of the `lstat64'
+- function to get information about an object in the
+- filesystems, not following symbolic links. It is used if the
+- `GLOB_ALTDIRFUNC' bit is set in the flag parameter. The type
+- of this field is `int (*) (const char *, struct stat64 *)'.
+-
+- This is a GNU extension.
+-
+- - Function: int glob (const char *PATTERN, int FLAGS, int (*ERRFUNC)
+- (const char *FILENAME, int ERROR-CODE), glob_t *VECTOR-PTR)
+- The function `glob' does globbing using the pattern PATTERN in the
+- current directory. It puts the result in a newly allocated
+- vector, and stores the size and address of this vector into
+- `*VECTOR-PTR'. The argument FLAGS is a combination of bit flags;
+- see *Note Flags for Globbing::, for details of the flags.
+-
+- The result of globbing is a sequence of file names. The function
+- `glob' allocates a string for each resulting word, then allocates
+- a vector of type `char **' to store the addresses of these
+- strings. The last element of the vector is a null pointer. This
+- vector is called the "word vector".
+-
+- To return this vector, `glob' stores both its address and its
+- length (number of elements, not counting the terminating null
+- pointer) into `*VECTOR-PTR'.
+-
+- Normally, `glob' sorts the file names alphabetically before
+- returning them. You can turn this off with the flag `GLOB_NOSORT'
+- if you want to get the information as fast as possible. Usually
+- it's a good idea to let `glob' sort them--if you process the files
+- in alphabetical order, the users will have a feel for the rate of
+- progress that your application is making.
+-
+- If `glob' succeeds, it returns 0. Otherwise, it returns one of
+- these error codes:
+-
+- `GLOB_ABORTED'
+- There was an error opening a directory, and you used the flag
+- `GLOB_ERR' or your specified ERRFUNC returned a nonzero value.
+- *Note Flags for Globbing::, for an explanation of the
+- `GLOB_ERR' flag and ERRFUNC.
+-
+- `GLOB_NOMATCH'
+- The pattern didn't match any existing files. If you use the
+- `GLOB_NOCHECK' flag, then you never get this error code,
+- because that flag tells `glob' to _pretend_ that the pattern
+- matched at least one file.
+-
+- `GLOB_NOSPACE'
+- It was impossible to allocate memory to hold the result.
+-
+- In the event of an error, `glob' stores information in
+- `*VECTOR-PTR' about all the matches it has found so far.
+-
+- It is important to notice that the `glob' function will not fail if
+- it encounters directories or files which cannot be handled without
+- the LFS interfaces. The implementation of `glob' is supposed to
+- use these functions internally. This at least is the assumptions
+- made by the Unix standard. The GNU extension of allowing the user
+- to provide own directory handling and `stat' functions complicates
+- things a bit. If these callback functions are used and a large
+- file or directory is encountered `glob' _can_ fail.
+-
+- - Function: int glob64 (const char *PATTERN, int FLAGS, int (*ERRFUNC)
+- (const char *FILENAME, int ERROR-CODE), glob64_t *VECTOR-PTR)
+- The `glob64' function was added as part of the Large File Summit
+- extensions but is not part of the original LFS proposal. The
+- reason for this is simple: it is not necessary. The necessity for
+- a `glob64' function is added by the extensions of the GNU `glob'
+- implementation which allows the user to provide own directory
+- handling and `stat' functions. The `readdir' and `stat' functions
+- do depend on the choice of `_FILE_OFFSET_BITS' since the definition
+- of the types `struct dirent' and `struct stat' will change
+- depending on the choice.
+-
+- Beside this difference the `glob64' works just like `glob' in all
+- aspects.
+-
+- This function is a GNU extension.

+-Flags for Globbing
+-------------------
+-
+- This section describes the flags that you can specify in the FLAGS
+-argument to `glob'. Choose the flags you want, and combine them with
+-the C bitwise OR operator `|'.
+-
+-`GLOB_APPEND'
+- Append the words from this expansion to the vector of words
+- produced by previous calls to `glob'. This way you can
+- effectively expand several words as if they were concatenated with
+- spaces between them.
+-
+- In order for appending to work, you must not modify the contents
+- of the word vector structure between calls to `glob'. And, if you
+- set `GLOB_DOOFFS' in the first call to `glob', you must also set
+- it when you append to the results.
+-
+- Note that the pointer stored in `gl_pathv' may no longer be valid
+- after you call `glob' the second time, because `glob' might have
+- relocated the vector. So always fetch `gl_pathv' from the
+- `glob_t' structure after each `glob' call; *never* save the
+- pointer across calls.
+-
+-`GLOB_DOOFFS'
+- Leave blank slots at the beginning of the vector of words. The
+- `gl_offs' field says how many slots to leave. The blank slots
+- contain null pointers.
+-
+-`GLOB_ERR'
+- Give up right away and report an error if there is any difficulty
+- reading the directories that must be read in order to expand
+- PATTERN fully. Such difficulties might include a directory in
+- which you don't have the requisite access. Normally, `glob' tries
+- its best to keep on going despite any errors, reading whatever
+- directories it can.
+-
+- You can exercise even more control than this by specifying an
+- error-handler function ERRFUNC when you call `glob'. If ERRFUNC
+- is not a null pointer, then `glob' doesn't give up right away when
+- it can't read a directory; instead, it calls ERRFUNC with two
+- arguments, like this:
+-
+- (*ERRFUNC) (FILENAME, ERROR-CODE)
+-
+- The argument FILENAME is the name of the directory that `glob'
+- couldn't open or couldn't read, and ERROR-CODE is the `errno'
+- value that was reported to `glob'.
+-
+- If the error handler function returns nonzero, then `glob' gives up
+- right away. Otherwise, it continues.
+-
+-`GLOB_MARK'
+- If the pattern matches the name of a directory, append `/' to the
+- directory's name when returning it.
+-
+-`GLOB_NOCHECK'
+- If the pattern doesn't match any file names, return the pattern
+- itself as if it were a file name that had been matched.
+- (Normally, when the pattern doesn't match anything, `glob' returns
+- that there were no matches.)
+-
+-`GLOB_NOSORT'
+- Don't sort the file names; return them in no particular order.
+- (In practice, the order will depend on the order of the entries in
+- the directory.) The only reason _not_ to sort is to save time.
+-
+-`GLOB_NOESCAPE'
+- Don't treat the `\' character specially in patterns. Normally,
+- `\' quotes the following character, turning off its special meaning
+- (if any) so that it matches only itself. When quoting is enabled,
+- the pattern `\?' matches only the string `?', because the question
+- mark in the pattern acts like an ordinary character.
+-
+- If you use `GLOB_NOESCAPE', then `\' is an ordinary character.
+-
+- `glob' does its work by calling the function `fnmatch' repeatedly.
+- It handles the flag `GLOB_NOESCAPE' by turning on the
+- `FNM_NOESCAPE' flag in calls to `fnmatch'.

+-More Flags for Globbing
+------------------------
+-
+- Beside the flags described in the last section, the GNU
+-implementation of `glob' allows a few more flags which are also defined
+-in the `glob.h' file. Some of the extensions implement functionality
+-which is available in modern shell implementations.
+-
+-`GLOB_PERIOD'
+- The `.' character (period) is treated special. It cannot be
+- matched by wildcards. *Note Wildcard Matching::, `FNM_PERIOD'.
+-
+-`GLOB_MAGCHAR'
+- The `GLOB_MAGCHAR' value is not to be given to `glob' in the FLAGS
+- parameter. Instead, `glob' sets this bit in the GL_FLAGS element
+- of the GLOB_T structure provided as the result if the pattern used
+- for matching contains any wildcard character.
+-
+-`GLOB_ALTDIRFUNC'
+- Instead of the using the using the normal functions for accessing
+- the filesystem the `glob' implementation uses the user-supplied
+- functions specified in the structure pointed to by PGLOB
+- parameter. For more information about the functions refer to the
+- sections about directory handling see *Note Accessing
+- Directories::, and *Note Reading Attributes::.
+-
+-`GLOB_BRACE'
+- If this flag is given the handling of braces in the pattern is
+- changed. It is now required that braces appear correctly grouped.
+- I.e., for each opening brace there must be a closing one. Braces
+- can be used recursively. So it is possible to define one brace
+- expression in another one. It is important to note that the range
+- of each brace expression is completely contained in the outer
+- brace expression (if there is one).
+-
+- The string between the matching braces is separated into single
+- expressions by splitting at `,' (comma) characters. The commas
+- themselves are discarded. Please note what we said above about
+- recursive brace expressions. The commas used to separate the
+- subexpressions must be at the same level. Commas in brace
+- subexpressions are not matched. They are used during expansion of
+- the brace expression of the deeper level. The example below shows
+- this
+-
+- glob ("{foo/{,bar,biz},baz}", GLOB_BRACE, NULL, &result)
+-
+- is equivalent to the sequence
+-
+- glob ("foo/", GLOB_BRACE, NULL, &result)
+- glob ("foo/bar", GLOB_BRACE|GLOB_APPEND, NULL, &result)
+- glob ("foo/biz", GLOB_BRACE|GLOB_APPEND, NULL, &result)
+- glob ("baz", GLOB_BRACE|GLOB_APPEND, NULL, &result)
+-
+- if we leave aside error handling.
+-
+-`GLOB_NOMAGIC'
+- If the pattern contains no wildcard constructs (it is a literal
+- file name), return it as the sole "matching" word, even if no file
+- exists by that name.
+-
+-`GLOB_TILDE'
+- If this flag is used the character `~' (tilde) is handled special
+- if it appears at the beginning of the pattern. Instead of being
+- taken verbatim it is used to represent the home directory of a
+- known user.
+-
+- If `~' is the only character in pattern or it is followed by a `/'
+- (slash), the home directory of the process owner is substituted.
+- Using `getlogin' and `getpwnam' the information is read from the
+- system databases. As an example take user `bart' with his home
+- directory at `/home/bart'. For him a call like
+-
+- glob ("~/bin/*", GLOB_TILDE, NULL, &result)
+-
+- would return the contents of the directory `/home/bart/bin'.
+- Instead of referring to the own home directory it is also possible
+- to name the home directory of other users. To do so one has to
+- append the user name after the tilde character. So the contents
+- of user `homer''s `bin' directory can be retrieved by
+-
+- glob ("~homer/bin/*", GLOB_TILDE, NULL, &result)
+-
+- If the user name is not valid or the home directory cannot be
+- determined for some reason the pattern is left untouched and
+- itself used as the result. I.e., if in the last example `home' is
+- not available the tilde expansion yields to `"~homer/bin/*"' and
+- `glob' is not looking for a directory named `~homer'.
+-
+- This functionality is equivalent to what is available in C-shells
+- if the `nonomatch' flag is set.
+-
+-`GLOB_TILDE_CHECK'
+- If this flag is used `glob' behaves like as if `GLOB_TILDE' is
+- given. The only difference is that if the user name is not
+- available or the home directory cannot be determined for other
+- reasons this leads to an error. `glob' will return `GLOB_NOMATCH'
+- instead of using the pattern itself as the name.
+-
+- This functionality is equivalent to what is available in C-shells
+- if `nonomatch' flag is not set.
+-
+-`GLOB_ONLYDIR'
+- If this flag is used the globbing function takes this as a *hint*
+- that the caller is only interested in directories matching the
+- pattern. If the information about the type of the file is easily
+- available non-directories will be rejected but no extra work will
+- be done to determine the information for each file. I.e., the
+- caller must still be able to filter directories out.
+-
+- This functionality is only available with the GNU `glob'
+- implementation. It is mainly used internally to increase the
+- performance but might be useful for a user as well and therefore is
+- documented here.
+-
+- Calling `glob' will in most cases allocate resources which are used
+-to represent the result of the function call. If the same object of
+-type `glob_t' is used in multiple call to `glob' the resources are
+-freed or reused so that no leaks appear. But this does not include the
+-time when all `glob' calls are done.
+-
+- - Function: void globfree (glob_t *PGLOB)
+- The `globfree' function frees all resources allocated by previous
+- calls to `glob' associated with the object pointed to by PGLOB.
+- This function should be called whenever the currently used
+- `glob_t' typed object isn't used anymore.
+-
+- - Function: void globfree64 (glob64_t *PGLOB)
+- This function is equivalent to `globfree' but it frees records of
+- type `glob64_t' which were allocated by `glob64'.

+-Regular Expression Matching
+-===========================
+-
+- The GNU C library supports two interfaces for matching regular
+-expressions. One is the standard POSIX.2 interface, and the other is
+-what the GNU system has had for many years.
+-
+- Both interfaces are declared in the header file `regex.h'. If you
+-define `_POSIX_C_SOURCE', then only the POSIX.2 functions, structures,
+-and constants are declared.

+-
+-POSIX Regular Expression Compilation
+-------------------------------------
+-
+- Before you can actually match a regular expression, you must
+-"compile" it. This is not true compilation--it produces a special data
+-structure, not machine instructions. But it is like ordinary
+-compilation in that its purpose is to enable you to "execute" the
+-pattern fast. (*Note Matching POSIX Regexps::, for how to use the
+-compiled regular expression for matching.)
+-
+- There is a special data type for compiled regular expressions:
+-
+- - Data Type: regex_t
+- This type of object holds a compiled regular expression. It is
+- actually a structure. It has just one field that your programs
+- should look at:
+-
+- `re_nsub'
+- This field holds the number of parenthetical subexpressions
+- in the regular expression that was compiled.
+-
+- There are several other fields, but we don't describe them here,
+- because only the functions in the library should use them.
+-
+- After you create a `regex_t' object, you can compile a regular
+-expression into it by calling `regcomp'.
+-
+- - Function: int regcomp (regex_t *COMPILED, const char *PATTERN, int
+- CFLAGS)
+- The function `regcomp' "compiles" a regular expression into a data
+- structure that you can use with `regexec' to match against a
+- string. The compiled regular expression format is designed for
+- efficient matching. `regcomp' stores it into `*COMPILED'.
+-
+- It's up to you to allocate an object of type `regex_t' and pass its
+- address to `regcomp'.
+-
+- The argument CFLAGS lets you specify various options that control
+- the syntax and semantics of regular expressions. *Note Flags for
+- POSIX Regexps::.
+-
+- If you use the flag `REG_NOSUB', then `regcomp' omits from the
+- compiled regular expression the information necessary to record
+- how subexpressions actually match. In this case, you might as well
+- pass `0' for the MATCHPTR and NMATCH arguments when you call
+- `regexec'.
+-
+- If you don't use `REG_NOSUB', then the compiled regular expression
+- does have the capacity to record how subexpressions match. Also,
+- `regcomp' tells you how many subexpressions PATTERN has, by
+- storing the number in `COMPILED->re_nsub'. You can use that value
+- to decide how long an array to allocate to hold information about
+- subexpression matches.
+-
+- `regcomp' returns `0' if it succeeds in compiling the regular
+- expression; otherwise, it returns a nonzero error code (see the
+- table below). You can use `regerror' to produce an error message
+- string describing the reason for a nonzero value; see *Note Regexp
+- Cleanup::.
+-
+-
+- Here are the possible nonzero values that `regcomp' can return:
+-
+-`REG_BADBR'
+- There was an invalid `\{...\}' construct in the regular
+- expression. A valid `\{...\}' construct must contain either a
+- single number, or two numbers in increasing order separated by a
+- comma.
+-
+-`REG_BADPAT'
+- There was a syntax error in the regular expression.
+-
+-`REG_BADRPT'
+- A repetition operator such as `?' or `*' appeared in a bad
+- position (with no preceding subexpression to act on).
+-
+-`REG_ECOLLATE'
+- The regular expression referred to an invalid collating element
+- (one not defined in the current locale for string collation).
+- *Note Locale Categories::.
+-
+-`REG_ECTYPE'
+- The regular expression referred to an invalid character class name.
+-
+-`REG_EESCAPE'
+- The regular expression ended with `\'.
+-
+-`REG_ESUBREG'
+- There was an invalid number in the `\DIGIT' construct.
+-
+-`REG_EBRACK'
+- There were unbalanced square brackets in the regular expression.
+-
+-`REG_EPAREN'
+- An extended regular expression had unbalanced parentheses, or a
+- basic regular expression had unbalanced `\(' and `\)'.
+-
+-`REG_EBRACE'
+- The regular expression had unbalanced `\{' and `\}'.
+-
+-`REG_ERANGE'
+- One of the endpoints in a range expression was invalid.
+-
+-`REG_ESPACE'
+- `regcomp' ran out of memory.

+- as a basic regular expression.
+-
+-`REG_ICASE'
+- Ignore case when matching letters.
+-
+-`REG_NOSUB'
+- Don't bother storing the contents of the MATCHES-PTR array.
+-
+-`REG_NEWLINE'
+- Treat a newline in STRING as dividing STRING into multiple lines,
+- so that `$' can match before the newline and `^' can match after.
+- Also, don't permit `.' to match a newline, and don't permit
+- `[^...]' to match a newline.
+-
+- Otherwise, newline acts like any other ordinary character.

+-
+-Matching a Compiled POSIX Regular Expression
+---------------------------------------------
+-
+- Once you have compiled a regular expression, as described in *Note
+-POSIX Regexp Compilation::, you can match it against strings using
+-`regexec'. A match anywhere inside the string counts as success,
+-unless the regular expression contains anchor characters (`^' or `$').
+-
+- - Function: int regexec (regex_t *COMPILED, char *STRING, size_t
+- NMATCH, regmatch_t MATCHPTR [], int EFLAGS)
+- This function tries to match the compiled regular expression
+- `*COMPILED' against STRING.
+-
+- `regexec' returns `0' if the regular expression matches;
+- otherwise, it returns a nonzero value. See the table below for
+- what nonzero values mean. You can use `regerror' to produce an
+- error message string describing the reason for a nonzero value;
+- see *Note Regexp Cleanup::.
+-
+- The argument EFLAGS is a word of bit flags that enable various
+- options.
+-
+- If you want to get information about what part of STRING actually
+- matched the regular expression or its subexpressions, use the
+- arguments MATCHPTR and NMATCH. Otherwise, pass `0' for NMATCH,
+- and `NULL' for MATCHPTR. *Note Regexp Subexpressions::.
+-
+- You must match the regular expression with the same set of current
+-locales that were in effect when you compiled the regular expression.
+-
+- The function `regexec' accepts the following flags in the EFLAGS
+-argument:
+-
+-`REG_NOTBOL'
+- Do not regard the beginning of the specified string as the
+- beginning of a line; more generally, don't make any assumptions
+- about what text might precede it.
+-
+-`REG_NOTEOL'
+- Do not regard the end of the specified string as the end of a
+- line; more generally, don't make any assumptions about what text
+- might follow it.
+-
+- Here are the possible nonzero values that `regexec' can return:
+-
+-`REG_NOMATCH'
+- The pattern didn't match the string. This isn't really an error.
+-
+-`REG_ESPACE'
+- `regexec' ran out of memory.

+-
+-Match Results with Subexpressions
+----------------------------------
+-
+- When `regexec' matches parenthetical subexpressions of PATTERN, it
+-records which parts of STRING they match. It returns that information
+-by storing the offsets into an array whose elements are structures of
+-type `regmatch_t'. The first element of the array (index `0') records
+-the part of the string that matched the entire regular expression.
+-Each other element of the array records the beginning and end of the
+-part that matched a single parenthetical subexpression.
+-
+- - Data Type: regmatch_t
+- This is the data type of the MATCHARRAY array that you pass to
+- `regexec'. It contains two structure fields, as follows:
+-
+- `rm_so'
+- The offset in STRING of the beginning of a substring. Add
+- this value to STRING to get the address of that part.
+-
+- `rm_eo'
+- The offset in STRING of the end of the substring.
+-
+- - Data Type: regoff_t
+- `regoff_t' is an alias for another signed integer type. The
+- fields of `regmatch_t' have type `regoff_t'.
+-
+- The `regmatch_t' elements correspond to subexpressions positionally;
+-the first element (index `1') records where the first subexpression
+-matched, the second element records the second subexpression, and so
+-on. The order of the subexpressions is the order in which they begin.
+-
+- When you call `regexec', you specify how long the MATCHPTR array is,
+-with the NMATCH argument. This tells `regexec' how many elements to
+-store. If the actual regular expression has more than NMATCH
+-subexpressions, then you won't get offset information about the rest of
+-them. But this doesn't alter whether the pattern matches a particular
+-string or not.
+-
+- If you don't want `regexec' to return any information about where
+-the subexpressions matched, you can either supply `0' for NMATCH, or
+-use the flag `REG_NOSUB' when you compile the pattern with `regcomp'.
+-
+-\1f
+-File: libc.info, Node: Subexpression Complications, Next: Regexp Cleanup, Prev: Regexp Subexpressions, Up: Regular Expressions
+-
+-Complications in Subexpression Matching
+----------------------------------------
+-
+- Sometimes a subexpression matches a substring of no characters. This
+-happens when `f\(o*\)' matches the string `fum'. (It really matches
+-just the `f'.) In this case, both of the offsets identify the point in
+-the string where the null substring was found. In this example, the
+-offsets are both `1'.
+-
+- Sometimes the entire regular expression can match without using some
+-of its subexpressions at all--for example, when `ba\(na\)*' matches the
+-string `ba', the parenthetical subexpression is not used. When this
+-happens, `regexec' stores `-1' in both fields of the element for that
+-subexpression.
+-
+- Sometimes matching the entire regular expression can match a
+-particular subexpression more than once--for example, when `ba\(na\)*'
+-matches the string `bananana', the parenthetical subexpression matches
+-three times. When this happens, `regexec' usually stores the offsets
+-of the last part of the string that matched the subexpression. In the
+-case of `bananana', these offsets are `6' and `8'.
+-
+- But the last match is not always the one that is chosen. It's more
+-accurate to say that the last _opportunity_ to match is the one that
+-takes precedence. What this means is that when one subexpression
+-appears within another, then the results reported for the inner
+-subexpression reflect whatever happened on the last match of the outer
+-subexpression. For an example, consider `\(ba\(na\)*s \)*' matching
+-the string `bananas bas '. The last time the inner expression actually
+-matches is near the end of the first word. But it is _considered_
+-again in the second word, and fails to match there. `regexec' reports
+-nonuse of the "na" subexpression.
+-
+- Another place where this rule applies is when the regular expression
+- \(ba\(na\)*s \|nefer\(ti\)* \)*
+-
+-matches `bananas nefertiti'. The "na" subexpression does match in the
+-first word, but it doesn't match in the second word because the other
+-alternative is used there. Once again, the second repetition of the
+-outer subexpression overrides the first, and within that second
+-repetition, the "na" subexpression is not used. So `regexec' reports
+-nonuse of the "na" subexpression.

+-
+-POSIX Regexp Matching Cleanup
+------------------------------
+-
+- When you are finished using a compiled regular expression, you can
+-free the storage it uses by calling `regfree'.
+-
+- - Function: void regfree (regex_t *COMPILED)
+- Calling `regfree' frees all the storage that `*COMPILED' points
+- to. This includes various internal fields of the `regex_t'
+- structure that aren't documented in this manual.
+-
+- `regfree' does not free the object `*COMPILED' itself.
+-
+- You should always free the space in a `regex_t' structure with
+-`regfree' before using the structure to compile another regular
+-expression.
+-
+- When `regcomp' or `regexec' reports an error, you can use the
+-function `regerror' to turn it into an error message string.
+-
+- - Function: size_t regerror (int ERRCODE, regex_t *COMPILED, char
+- *BUFFER, size_t LENGTH)
+- This function produces an error message string for the error code
+- ERRCODE, and stores the string in LENGTH bytes of memory starting
+- at BUFFER. For the COMPILED argument, supply the same compiled
+- regular expression structure that `regcomp' or `regexec' was
+- working with when it got the error. Alternatively, you can supply
+- `NULL' for COMPILED; you will still get a meaningful error
+- message, but it might not be as detailed.
+-
+- If the error message can't fit in LENGTH bytes (including a
+- terminating null character), then `regerror' truncates it. The
+- string that `regerror' stores is always null-terminated even if it
+- has been truncated.
+-
+- The return value of `regerror' is the minimum length needed to
+- store the entire error message. If this is less than LENGTH, then
+- the error message was not truncated, and you can use it.
+- Otherwise, you should call `regerror' again with a larger buffer.
+-
+- Here is a function which uses `regerror', but always dynamically
+- allocates a buffer for the error message:
+-
+- char *get_regerror (int errcode, regex_t *compiled)
+- {
+- size_t length = regerror (errcode, compiled, NULL, 0);
+- char *buffer = xmalloc (length);
+- (void) regerror (errcode, compiled, buffer, length);

+-Shell-Style Word Expansion
+-==========================
+-
+- "Word expansion" means the process of splitting a string into
+-"words" and substituting for variables, commands, and wildcards just as
+-the shell does.
+-
+- For example, when you write `ls -l foo.c', this string is split into
+-three separate words--`ls', `-l' and `foo.c'. This is the most basic
+-function of word expansion.
+-
+- When you write `ls *.c', this can become many words, because the
+-word `*.c' can be replaced with any number of file names. This is
+-called "wildcard expansion", and it is also a part of word expansion.
+-
+- When you use `echo $PATH' to print your path, you are taking
+-advantage of "variable substitution", which is also part of word
+-expansion.
+-
+- Ordinary programs can perform word expansion just like the shell by
+-calling the library function `wordexp'.

+-
+-The Stages of Word Expansion
+-----------------------------
+-
+- When word expansion is applied to a sequence of words, it performs
+-the following transformations in the order shown here:
+-
+- 1. "Tilde expansion": Replacement of `~foo' with the name of the home
+- directory of `foo'.
+-
+- 2. Next, three different transformations are applied in the same step,
+- from left to right:
+-
+- * "Variable substitution": Environment variables are
+- substituted for references such as `$foo'.
+-
+- * "Command substitution": Constructs such as ``cat foo`' and
+- the equivalent `$(cat foo)' are replaced with the output from
+- the inner command.
+-
+- * "Arithmetic expansion": Constructs such as `$(($x-1))' are
+- replaced with the result of the arithmetic computation.
+-
+- 3. "Field splitting": subdivision of the text into "words".
+-
+- 4. "Wildcard expansion": The replacement of a construct such as `*.c'
+- with a list of `.c' file names. Wildcard expansion applies to an
+- entire word at a time, and replaces that word with 0 or more file
+- names that are themselves words.
+-
+- 5. "Quote removal": The deletion of string-quotes, now that they have
+- done their job by inhibiting the above transformations when
+- appropriate.
+-
+- For the details of these transformations, and how to write the
+-constructs that use them, see `The BASH Manual' (to appear).

+-
+-Calling `wordexp'
+------------------
+-
+- All the functions, constants and data types for word expansion are
+-declared in the header file `wordexp.h'.
+-
+- Word expansion produces a vector of words (strings). To return this
+-vector, `wordexp' uses a special data type, `wordexp_t', which is a
+-structure. You pass `wordexp' the address of the structure, and it
+-fills in the structure's fields to tell you about the results.
+-
+- - Data Type: wordexp_t
+- This data type holds a pointer to a word vector. More precisely,
+- it records both the address of the word vector and its size.
+-
+- `we_wordc'
+- The number of elements in the vector.
+-
+- `we_wordv'
+- The address of the vector. This field has type `char **'.
+-
+- `we_offs'
+- The offset of the first real element of the vector, from its
+- nominal address in the `we_wordv' field. Unlike the other
+- fields, this is always an input to `wordexp', rather than an
+- output from it.
+-
+- If you use a nonzero offset, then that many elements at the
+- beginning of the vector are left empty. (The `wordexp'
+- function fills them with null pointers.)
+-
+- The `we_offs' field is meaningful only if you use the
+- `WRDE_DOOFFS' flag. Otherwise, the offset is always zero
+- regardless of what is in this field, and the first real
+- element comes at the beginning of the vector.
+-
+- - Function: int wordexp (const char *WORDS, wordexp_t
+- *WORD-VECTOR-PTR, int FLAGS)
+- Perform word expansion on the string WORDS, putting the result in
+- a newly allocated vector, and store the size and address of this
+- vector into `*WORD-VECTOR-PTR'. The argument FLAGS is a
+- combination of bit flags; see *Note Flags for Wordexp::, for
+- details of the flags.
+-
+- You shouldn't use any of the characters `|&;<>' in the string
+- WORDS unless they are quoted; likewise for newline. If you use
+- these characters unquoted, you will get the `WRDE_BADCHAR' error
+- code. Don't use parentheses or braces unless they are quoted or
+- part of a word expansion construct. If you use quotation
+- characters `'"`', they should come in pairs that balance.
+-
+- The results of word expansion are a sequence of words. The
+- function `wordexp' allocates a string for each resulting word, then
+- allocates a vector of type `char **' to store the addresses of
+- these strings. The last element of the vector is a null pointer.
+- This vector is called the "word vector".
+-
+- To return this vector, `wordexp' stores both its address and its
+- length (number of elements, not counting the terminating null
+- pointer) into `*WORD-VECTOR-PTR'.
+-
+- If `wordexp' succeeds, it returns 0. Otherwise, it returns one of
+- these error codes:
+-
+- `WRDE_BADCHAR'
+- The input string WORDS contains an unquoted invalid character
+- such as `|'.
+-
+- `WRDE_BADVAL'
+- The input string refers to an undefined shell variable, and
+- you used the flag `WRDE_UNDEF' to forbid such references.
+-
+- `WRDE_CMDSUB'
+- The input string uses command substitution, and you used the
+- flag `WRDE_NOCMD' to forbid command substitution.
+-
+- `WRDE_NOSPACE'
+- It was impossible to allocate memory to hold the result. In
+- this case, `wordexp' can store part of the results--as much
+- as it could allocate room for.
+-
+- `WRDE_SYNTAX'
+- There was a syntax error in the input string. For example,
+- an unmatched quoting character is a syntax error.

+-Flags for Word Expansion
+-------------------------
+-
+- This section describes the flags that you can specify in the FLAGS
+-argument to `wordexp'. Choose the flags you want, and combine them
+-with the C operator `|'.
+-
+-`WRDE_APPEND'
+- Append the words from this expansion to the vector of words
+- produced by previous calls to `wordexp'. This way you can
+- effectively expand several words as if they were concatenated with
+- spaces between them.
+-
+- In order for appending to work, you must not modify the contents
+- of the word vector structure between calls to `wordexp'. And, if
+- you set `WRDE_DOOFFS' in the first call to `wordexp', you must also
+- set it when you append to the results.
+-
+-`WRDE_DOOFFS'
+- Leave blank slots at the beginning of the vector of words. The
+- `we_offs' field says how many slots to leave. The blank slots
+- contain null pointers.
+-
+-`WRDE_NOCMD'
+- Don't do command substitution; if the input requests command
+- substitution, report an error.
+-
+-`WRDE_REUSE'
+- Reuse a word vector made by a previous call to `wordexp'. Instead
+- of allocating a new vector of words, this call to `wordexp' will
+- use the vector that already exists (making it larger if necessary).
+-
+- Note that the vector may move, so it is not safe to save an old
+- pointer and use it again after calling `wordexp'. You must fetch
+- `we_pathv' anew after each call.
+-
+-`WRDE_SHOWERR'
+- Do show any error messages printed by commands run by command
+- substitution. More precisely, allow these commands to inherit the
+- standard error output stream of the current process. By default,
+- `wordexp' gives these commands a standard error stream that
+- discards all output.
+-
+-`WRDE_UNDEF'
+- If the input refers to a shell variable that is not defined,
+- report an error.

+-
+-Details of Tilde Expansion
+---------------------------
+-
+- It's a standard part of shell syntax that you can use `~' at the
+-beginning of a file name to stand for your own home directory. You can
+-use `~USER' to stand for USER's home directory.
+-
+- "Tilde expansion" is the process of converting these abbreviations
+-to the directory names that they stand for.
+-
+- Tilde expansion applies to the `~' plus all following characters up
+-to whitespace or a slash. It takes place only at the beginning of a
+-word, and only if none of the characters to be transformed is quoted in
+-any way.
+-
+- Plain `~' uses the value of the environment variable `HOME' as the
+-proper home directory name. `~' followed by a user name uses
+-`getpwname' to look up that user in the user database, and uses
+-whatever directory is recorded there. Thus, `~' followed by your own
+-name can give different results from plain `~', if the value of `HOME'
+-is not really your home directory.
+-
+-\1f
+-File: libc.info, Node: Variable Substitution, Prev: Tilde Expansion, Up: Word Expansion
+-
+-Details of Variable Substitution
+---------------------------------
+-
+- Part of ordinary shell syntax is the use of `$VARIABLE' to
+-substitute the value of a shell variable into a command. This is called
+-"variable substitution", and it is one part of doing word expansion.
+-
+- There are two basic ways you can write a variable reference for
+-substitution:
+-
+-`${VARIABLE}'
+- If you write braces around the variable name, then it is completely
+- unambiguous where the variable name ends. You can concatenate
+- additional letters onto the end of the variable value by writing
+- them immediately after the close brace. For example, `${foo}s'
+- expands into `tractors'.
+-
+-`$VARIABLE'
+- If you do not put braces around the variable name, then the
+- variable name consists of all the alphanumeric characters and
+- underscores that follow the `$'. The next punctuation character
+- ends the variable name. Thus, `$foo-bar' refers to the variable
+- `foo' and expands into `tractor-bar'.
+-
+- When you use braces, you can also use various constructs to modify
+-the value that is substituted, or test it in various ways.
+-
+-`${VARIABLE:-DEFAULT}'
+- Substitute the value of VARIABLE, but if that is empty or
+- undefined, use DEFAULT instead.
+-
+-`${VARIABLE:=DEFAULT}'
+- Substitute the value of VARIABLE, but if that is empty or
+- undefined, use DEFAULT instead and set the variable to DEFAULT.
+-
+-`${VARIABLE:?MESSAGE}'
+- If VARIABLE is defined and not empty, substitute its value.
+-
+- Otherwise, print MESSAGE as an error message on the standard error
+- stream, and consider word expansion a failure.
+-
+-`${VARIABLE:+REPLACEMENT}'
+- Substitute REPLACEMENT, but only if VARIABLE is defined and
+- nonempty. Otherwise, substitute nothing for this construct.
+-
+-`${#VARIABLE}'
+- Substitute a numeral which expresses in base ten the number of
+- characters in the value of VARIABLE. `${#foo}' stands for `7',
+- because `tractor' is seven characters.
+-
+- These variants of variable substitution let you remove part of the
+-variable's value before substituting it. The PREFIX and SUFFIX are not
+-mere strings; they are wildcard patterns, just like the patterns that
+-you use to match multiple file names. But in this context, they match
+-against parts of the variable value rather than against file names.
+-
+-`${VARIABLE%%SUFFIX}'
+- Substitute the value of VARIABLE, but first discard from that
+- variable any portion at the end that matches the pattern SUFFIX.
+-
+- If there is more than one alternative for how to match against
+- SUFFIX, this construct uses the longest possible match.
+-
+- Thus, `${foo%%r*}' substitutes `t', because the largest match for
+- `r*' at the end of `tractor' is `ractor'.
+-
+-`${VARIABLE%SUFFIX}'
+- Substitute the value of VARIABLE, but first discard from that
+- variable any portion at the end that matches the pattern SUFFIX.
+-
+- If there is more than one alternative for how to match against
+- SUFFIX, this construct uses the shortest possible alternative.
+-
+- Thus, `${foo%r*}' substitutes `tracto', because the shortest match
+- for `r*' at the end of `tractor' is just `r'.
+-
+-`${VARIABLE##PREFIX}'
+- Substitute the value of VARIABLE, but first discard from that
+- variable any portion at the beginning that matches the pattern
+- PREFIX.
+-
+- If there is more than one alternative for how to match against
+- PREFIX, this construct uses the longest possible match.
+-
+- Thus, `${foo##*t}' substitutes `or', because the largest match for
+- `*t' at the beginning of `tractor' is `tract'.
+-
+-`${VARIABLE#PREFIX}'
+- Substitute the value of VARIABLE, but first discard from that
+- variable any portion at the beginning that matches the pattern
+- PREFIX.
+-
+- If there is more than one alternative for how to match against
+- PREFIX, this construct uses the shortest possible alternative.
+-
+- Thus, `${foo#*t}' substitutes `ractor', because the shortest match
+- for `*t' at the beginning of `tractor' is just `t'.

+-

+-is most appropriate!

+-and output. Other chapters relating to the GNU I/O facilities are:

+-Input/Output Concepts
+-=====================
+-
+- Before you can read or write the contents of a file, you must
+-establish a connection or communications channel to the file. This
+-process is called "opening" the file. You can open a file for reading,
+-writing, or both.
+-
+- The connection to an open file is represented either as a stream or
+-as a file descriptor. You pass this as an argument to the functions
+-that do the actual read or write operations, to tell them which file to
+-operate on. Certain functions expect streams, and others are designed
+-to operate on file descriptors.
+-
+- When you have finished reading to or writing from the file, you can
+-terminate the connection by "closing" the file. Once you have closed a
+-stream or file descriptor, you cannot do any more input or output
+-operations on it.

+-
+-Streams and File Descriptors
+-----------------------------
+-
+- When you want to do input or output to a file, you have a choice of
+-two basic mechanisms for representing the connection between your
+-program and the file: file descriptors and streams. File descriptors
+-are represented as objects of type `int', while streams are represented
+-as `FILE *' objects.
+-
+- File descriptors provide a primitive, low-level interface to input
+-and output operations. Both file descriptors and streams can represent
+-a connection to a device (such as a terminal), or a pipe or socket for
+-communicating with another process, as well as a normal file. But, if
+-you want to do control operations that are specific to a particular kind
+-of device, you must use a file descriptor; there are no facilities to
+-use streams in this way. You must also use file descriptors if your
+-program needs to do input or output in special modes, such as
+-nonblocking (or polled) input (*note File Status Flags::).
+-
+- Streams provide a higher-level interface, layered on top of the
+-primitive file descriptor facilities. The stream interface treats all
+-kinds of files pretty much alike--the sole exception being the three
+-styles of buffering that you can choose (*note Stream Buffering::).
+-
+- The main advantage of using the stream interface is that the set of
+-functions for performing actual input and output operations (as opposed
+-to control operations) on streams is much richer and more powerful than
+-the corresponding facilities for file descriptors. The file descriptor
+-interface provides only simple functions for transferring blocks of
+-characters, but the stream interface also provides powerful formatted
+-input and output functions (`printf' and `scanf') as well as functions
+-for character- and line-oriented input and output.
+-
+- Since streams are implemented in terms of file descriptors, you can
+-extract the file descriptor from a stream and perform low-level
+-operations directly on the file descriptor. You can also initially open
+-a connection as a file descriptor and then make a stream associated with
+-that file descriptor.
+-
+- In general, you should stick with using streams rather than file
+-descriptors, unless there is some specific operation you want to do that
+-can only be done on a file descriptor. If you are a beginning
+-programmer and aren't sure what functions to use, we suggest that you
+-concentrate on the formatted input functions (*note Formatted Input::)
+-and formatted output functions (*note Formatted Output::).
+-
+- If you are concerned about portability of your programs to systems
+-other than GNU, you should also be aware that file descriptors are not
+-as portable as streams. You can expect any system running ISO C to
+-support streams, but non-GNU systems may not support file descriptors at
+-all, or may only implement a subset of the GNU functions that operate on
+-file descriptors. Most of the file descriptor functions in the GNU
+-library are included in the POSIX.1 standard, however.
+-
+-\1f
+-File: libc.info, Node: File Position, Prev: Streams and File Descriptors, Up: I/O Concepts
+-
+-File Position
+--------------
+-
+- One of the attributes of an open file is its "file position" that
+-keeps track of where in the file the next character is to be read or
+-written. In the GNU system, and all POSIX.1 systems, the file position
+-is simply an integer representing the number of bytes from the beginning
+-of the file.
+-
+- The file position is normally set to the beginning of the file when
+-it is opened, and each time a character is read or written, the file
+-position is incremented. In other words, access to the file is normally
+-"sequential".
+-
+- Ordinary files permit read or write operations at any position within
+-the file. Some other kinds of files may also permit this. Files which
+-do permit this are sometimes referred to as "random-access" files. You
+-can change the file position using the `fseek' function on a stream
+-(*note File Positioning::) or the `lseek' function on a file descriptor
+-(*note I/O Primitives::). If you try to change the file position on a
+-file that doesn't support random access, you get the `ESPIPE' error.
+-
+- Streams and descriptors that are opened for "append access" are
+-treated specially for output: output to such files is _always_ appended
+-sequentially to the _end_ of the file, regardless of the file position.
+-However, the file position is still used to control where in the file
+-reading is done.
+-
+- If you think about it, you'll realize that several programs can read
+-a given file at the same time. In order for each program to be able to
+-read the file at its own pace, each program must have its own file
+-pointer, which is not affected by anything the other programs do.
+-
+- In fact, each opening of a file creates a separate file position.
+-Thus, if you open a file twice even in the same program, you get two
+-streams or descriptors with independent file positions.
+-
+- By contrast, if you open a descriptor and then duplicate it to get
+-another descriptor, these two descriptors share the same file position:
+-changing the file position of one descriptor will affect the other.

+-
+-File Names
+-==========
+-
+- In order to open a connection to a file, or to perform other
+-operations such as deleting a file, you need some way to refer to the
+-file. Nearly all files have names that are strings--even files which
+-are actually devices such as tape drives or terminals. These strings
+-are called "file names". You specify the file name to say which file
+-you want to open or operate on.
+-
+- This section describes the conventions for file names and how the
+-operating system works with them.

+-File: libc.info, Node: Directories, Next: File Name Resolution, Up: File Names
+-
+-Directories
+------------
+-
+- In order to understand the syntax of file names, you need to
+-understand how the file system is organized into a hierarchy of
+-directories.
+-
+- A "directory" is a file that contains information to associate other
+-files with names; these associations are called "links" or "directory
+-entries". Sometimes, people speak of "files in a directory", but in
+-reality, a directory only contains pointers to files, not the files
+-themselves.
+-
+- The name of a file contained in a directory entry is called a "file
+-name component". In general, a file name consists of a sequence of one
+-or more such components, separated by the slash character (`/'). A
+-file name which is just one component names a file with respect to its
+-directory. A file name with multiple components names a directory, and
+-then a file in that directory, and so on.
+-
+- Some other documents, such as the POSIX standard, use the term
+-"pathname" for what we call a file name, and either "filename" or
+-"pathname component" for what this manual calls a file name component.
+-We don't use this terminology because a "path" is something completely
+-different (a list of directories to search), and we think that
+-"pathname" used for something else will confuse users. We always use
+-"file name" and "file name component" (or sometimes just "component",
+-where the context is obvious) in GNU documentation. Some macros use
+-the POSIX terminology in their names, such as `PATH_MAX'. These macros
+-are defined by the POSIX standard, so we cannot change their names.
+-
+- You can find more detailed information about operations on
+-directories in *Note File System Interface::.
+-
+-\1f
+-File: libc.info, Node: File Name Resolution, Next: File Name Errors, Prev: Directories, Up: File Names
+-
+-File Name Resolution
+---------------------
+-
+- A file name consists of file name components separated by slash
+-(`/') characters. On the systems that the GNU C library supports,
+-multiple successive `/' characters are equivalent to a single `/'
+-character.
+-
+- The process of determining what file a file name refers to is called
+-"file name resolution". This is performed by examining the components
+-that make up a file name in left-to-right order, and locating each
+-successive component in the directory named by the previous component.
+-Of course, each of the files that are referenced as directories must
+-actually exist, be directories instead of regular files, and have the
+-appropriate permissions to be accessible by the process; otherwise the
+-file name resolution fails.
+-
+- If a file name begins with a `/', the first component in the file
+-name is located in the "root directory" of the process (usually all
+-processes on the system have the same root directory). Such a file name
+-is called an "absolute file name".
+-
+- Otherwise, the first component in the file name is located in the
+-current working directory (*note Working Directory::). This kind of
+-file name is called a "relative file name".
+-
+- The file name components `.' ("dot") and `..' ("dot-dot") have
+-special meanings. Every directory has entries for these file name
+-components. The file name component `.' refers to the directory
+-itself, while the file name component `..' refers to its "parent
+-directory" (the directory that contains the link for the directory in
+-question). As a special case, `..' in the root directory refers to the
+-root directory itself, since it has no parent; thus `/..' is the same
+-as `/'.
+-
+- Here are some examples of file names:
+-
+-`/a'
+- The file named `a', in the root directory.
+-
+-`/a/b'
+- The file named `b', in the directory named `a' in the root
+- directory.
+-
+-`a'
+- The file named `a', in the current working directory.
+-
+-`/a/./b'
+- This is the same as `/a/b'.
+-
+-`./a'
+- The file named `a', in the current working directory.
+-
+-`../a'
+- The file named `a', in the parent directory of the current working
+- directory.
+-
+- A file name that names a directory may optionally end in a `/'. You
+-can specify a file name of `/' to refer to the root directory, but the
+-empty string is not a meaningful file name. If you want to refer to
+-the current working directory, use a file name of `.' or `./'.
+-
+- Unlike some other operating systems, the GNU system doesn't have any
+-built-in support for file types (or extensions) or file versions as part
+-of its file name syntax. Many programs and utilities use conventions
+-for file names--for example, files containing C source code usually
+-have names suffixed with `.c'--but there is nothing in the file system
+-itself that enforces this kind of convention.

+-File Name Errors
+-----------------
+-
+- Functions that accept file name arguments usually detect these
+-`errno' error conditions relating to the file name syntax or trouble
+-finding the named file. These errors are referred to throughout this
+-manual as the "usual file name errors".
+-
+-`EACCES'
+- The process does not have search permission for a directory
+- component of the file name.
+-
+-`ENAMETOOLONG'
+- This error is used when either the total length of a file name is
+- greater than `PATH_MAX', or when an individual file name component
+- has a length greater than `NAME_MAX'. *Note Limits for Files::.
+-
+- In the GNU system, there is no imposed limit on overall file name
+- length, but some file systems may place limits on the length of a
+- component.
+-
+-`ENOENT'
+- This error is reported when a file referenced as a directory
+- component in the file name doesn't exist, or when a component is a
+- symbolic link whose target file does not exist. *Note Symbolic
+- Links::.
+-
+-`ENOTDIR'
+- A file that is referenced as a directory component in the file name
+- exists, but it isn't a directory.
+-
+-`ELOOP'
+- Too many symbolic links were resolved while trying to look up the
+- file name. The system has an arbitrary limit on the number of
+- symbolic links that may be resolved in looking up a single file
+- name, as a primitive way to detect loops. *Note Symbolic Links::.

+-
+-Portability of File Names
+--------------------------
+-
+- The rules for the syntax of file names discussed in *Note File
+-Names::, are the rules normally used by the GNU system and by other
+-POSIX systems. However, other operating systems may use other
+-conventions.
+-
+- There are two reasons why it can be important for you to be aware of
+-file name portability issues:
+-
+- * If your program makes assumptions about file name syntax, or
+- contains embedded literal file name strings, it is more difficult
+- to get it to run under other operating systems that use different
+- syntax conventions.
+-
+- * Even if you are not concerned about running your program on
+- machines that run other operating systems, it may still be
+- possible to access files that use different naming conventions.
+- For example, you may be able to access file systems on another
+- computer running a different operating system over a network, or
+- read and write disks in formats used by other operating systems.
+-
+- The ISO C standard says very little about file name syntax, only that
+-file names are strings. In addition to varying restrictions on the
+-length of file names and what characters can validly appear in a file
+-name, different operating systems use different conventions and syntax
+-for concepts such as structured directories and file types or
+-extensions. Some concepts such as file versions might be supported in
+-some operating systems and not by others.
+-
+- The POSIX.1 standard allows implementations to put additional
+-restrictions on file name syntax, concerning what characters are
+-permitted in file names and on the length of file name and file name
+-component strings. However, in the GNU system, you do not need to worry
+-about these restrictions; any character except the null character is
+-permitted in a file name string, and there are no limits on the length
+-of file name strings.

+-Streams
+-=======
+-
+- For historical reasons, the type of the C data structure that
+-represents a stream is called `FILE' rather than "stream". Since most
+-of the library functions deal with objects of type `FILE *', sometimes
+-the term "file pointer" is also used to mean "stream". This leads to
+-unfortunate confusion over terminology in many books on C. This
+-manual, however, is careful to use the terms "file" and "stream" only
+-in the technical sense.
+-
+- The `FILE' type is declared in the header file `stdio.h'.
+-
+- - Data Type: FILE
+- This is the data type used to represent stream objects. A `FILE'
+- object holds all of the internal state information about the
+- connection to the associated file, including such things as the
+- file position indicator and buffering information. Each stream
+- also has error and end-of-file status indicators that can be
+- tested with the `ferror' and `feof' functions; see *Note EOF and
+- Errors::.
+-
+- `FILE' objects are allocated and managed internally by the
+-input/output library functions. Don't try to create your own objects of
+-type `FILE'; let the library do it. Your programs should deal only
+-with pointers to these objects (that is, `FILE *' values) rather than
+-the objects themselves.

+-Standard Streams
+-================

+- These streams are declared in the header file `stdio.h'.
+-
+- - Variable: FILE * stdin
+- The "standard input" stream, which is the normal source of input
+- for the program.
+-
+- - Variable: FILE * stdout
+- The "standard output" stream, which is used for normal output from
+- the program.
+-
+- - Variable: FILE * stderr
+- The "standard error" stream, which is used for error messages and
+- diagnostics issued by the program.
+-
+- In the GNU system, you can specify what files or processes
+-correspond to these streams using the pipe and redirection facilities
+-provided by the shell. (The primitives shells use to implement these
+-facilities are described in *Note File System Interface::.) Most other
+-operating systems provide similar mechanisms, but the details of how to
+-use them can vary.
+-
+- In the GNU C library, `stdin', `stdout', and `stderr' are normal
+-variables which you can set just like any others. For example, to
+-redirect the standard output to a file, you could do:
+-
+- fclose (stdout);
+- stdout = fopen ("standard-output-file", "w");
+-
+- Note however, that in other systems `stdin', `stdout', and `stderr'
+-are macros that you cannot assign to in the normal way. But you can
+-use `freopen' to get the effect of closing one and reopening it. *Note
+-Opening Streams::.
+-
+- The three streams `stdin', `stdout', and `stderr' are not unoriented
+-at program start (*note Streams and I18N::).

+-
+-Opening Streams
+-===============
+-
+- Opening a file with the `fopen' function creates a new stream and
+-establishes a connection between the stream and a file. This may
+-involve creating a new file.
+-
+- Everything described in this section is declared in the header file
+-`stdio.h'.
+-
+- - Function: FILE * fopen (const char *FILENAME, const char *OPENTYPE)
+- The `fopen' function opens a stream for I/O to the file FILENAME,
+- and returns a pointer to the stream.
+-
+- The OPENTYPE argument is a string that controls how the file is
+- opened and specifies attributes of the resulting stream. It must
+- begin with one of the following sequences of characters:
+-
+- `r'
+- Open an existing file for reading only.
+-
+- `w'
+- Open the file for writing only. If the file already exists,
+- it is truncated to zero length. Otherwise a new file is
+- created.
+-
+- `a'
+- Open a file for append access; that is, writing at the end of
+- file only. If the file already exists, its initial contents
+- are unchanged and output to the stream is appended to the end
+- of the file. Otherwise, a new, empty file is created.
+-
+- `r+'
+- Open an existing file for both reading and writing. The
+- initial contents of the file are unchanged and the initial
+- file position is at the beginning of the file.
+-
+- `w+'
+- Open a file for both reading and writing. If the file
+- already exists, it is truncated to zero length. Otherwise, a
+- new file is created.
+-
+- `a+'
+- Open or create file for both reading and appending. If the
+- file exists, its initial contents are unchanged. Otherwise,
+- a new file is created. The initial file position for reading
+- is at the beginning of the file, but output is always
+- appended to the end of the file.
+-
+- As you can see, `+' requests a stream that can do both input and
+- output. The ISO standard says that when using such a stream, you
+- must call `fflush' (*note Stream Buffering::) or a file positioning
+- function such as `fseek' (*note File Positioning::) when switching
+- from reading to writing or vice versa. Otherwise, internal buffers
+- might not be emptied properly. The GNU C library does not have
+- this limitation; you can do arbitrary reading and writing
+- operations on a stream in whatever order.
+-
+- Additional characters may appear after these to specify flags for
+- the call. Always put the mode (`r', `w+', etc.) first; that is
+- the only part you are guaranteed will be understood by all systems.
+-
+- The GNU C library defines one additional character for use in
+- OPENTYPE: the character `x' insists on creating a new file--if a
+- file FILENAME already exists, `fopen' fails rather than opening
+- it. If you use `x' you are guaranteed that you will not clobber
+- an existing file. This is equivalent to the `O_EXCL' option to
+- the `open' function (*note Opening and Closing Files::).
+-
+- The character `b' in OPENTYPE has a standard meaning; it requests
+- a binary stream rather than a text stream. But this makes no
+- difference in POSIX systems (including the GNU system). If both
+- `+' and `b' are specified, they can appear in either order. *Note
+- Binary Streams::.
+-
+- If the OPENTYPE string contains the sequence `,ccs=STRING' then
+- STRING is taken as the name of a coded character set and `fopen'
+- will mark the stream as wide-oriented which appropriate conversion
+- functions in place to convert from and to the character set STRING
+- is place. Any other stream is opened initially unoriented and the
+- orientation is decided with the first file operation. If the
+- first operation is a wide character operation, the stream is not
+- only marked as wide-oriented, also the conversion functions to
+- convert to the coded character set used for the current locale are
+- loaded. This will not change anymore from this point on even if
+- the locale selected for the `LC_CTYPE' category is changed.
+-
+- Any other characters in OPENTYPE are simply ignored. They may be
+- meaningful in other systems.
+-
+- If the open fails, `fopen' returns a null pointer.
+-
+- When the sources are compiling with `_FILE_OFFSET_BITS == 64' on a
+- 32 bit machine this function is in fact `fopen64' since the LFS
+- interface replaces transparently the old interface.
+-
+- You can have multiple streams (or file descriptors) pointing to the
+-same file open at the same time. If you do only input, this works
+-straightforwardly, but you must be careful if any output streams are
+-included. *Note Stream/Descriptor Precautions::. This is equally true
+-whether the streams are in one program (not usual) or in several
+-programs (which can easily happen). It may be advantageous to use the
+-file locking facilities to avoid simultaneous access. *Note File
+-Locks::.
+-
+- - Function: FILE * fopen64 (const char *FILENAME, const char *OPENTYPE)
+- This function is similar to `fopen' but the stream it returns a
+- pointer for is opened using `open64'. Therefore this stream can be
+- used even on files larger then 2^31 bytes on 32 bit machines.
+-
+- Please note that the return type is still `FILE *'. There is no
+- special `FILE' type for the LFS interface.
+-
+- If the sources are compiled with `_FILE_OFFSET_BITS == 64' on a 32
+- bits machine this function is available under the name `fopen' and
+- so transparently replaces the old interface.
+-
+- - Macro: int FOPEN_MAX
+- The value of this macro is an integer constant expression that
+- represents the minimum number of streams that the implementation
+- guarantees can be open simultaneously. You might be able to open
+- more than this many streams, but that is not guaranteed. The
+- value of this constant is at least eight, which includes the three
+- standard streams `stdin', `stdout', and `stderr'. In POSIX.1
+- systems this value is determined by the `OPEN_MAX' parameter;
+- *note General Limits::. In BSD and GNU, it is controlled by the
+- `RLIMIT_NOFILE' resource limit; *note Limits on Resources::.
+-
+- - Function: FILE * freopen (const char *FILENAME, const char
+- *OPENTYPE, FILE *STREAM)
+- This function is like a combination of `fclose' and `fopen'. It
+- first closes the stream referred to by STREAM, ignoring any errors
+- that are detected in the process. (Because errors are ignored,
+- you should not use `freopen' on an output stream if you have
+- actually done any output using the stream.) Then the file named by
+- FILENAME is opened with mode OPENTYPE as for `fopen', and
+- associated with the same stream object STREAM.
+-
+- If the operation fails, a null pointer is returned; otherwise,
+- `freopen' returns STREAM.
+-
+- `freopen' has traditionally been used to connect a standard stream
+- such as `stdin' with a file of your own choice. This is useful in
+- programs in which use of a standard stream for certain purposes is
+- hard-coded. In the GNU C library, you can simply close the
+- standard streams and open new ones with `fopen'. But other
+- systems lack this ability, so using `freopen' is more portable.
+-
+- When the sources are compiling with `_FILE_OFFSET_BITS == 64' on a
+- 32 bit machine this function is in fact `freopen64' since the LFS
+- interface replaces transparently the old interface.
+-
+- - Function: FILE * freopen64 (const char *FILENAME, const char
+- *OPENTYPE, FILE *STREAM)
+- This function is similar to `freopen'. The only difference is that
+- on 32 bit machine the stream returned is able to read beyond the
+- 2^31 bytes limits imposed by the normal interface. It should be
+- noted that the stream pointed to by STREAM need not be opened
+- using `fopen64' or `freopen64' since its mode is not important for
+- this function.
+-
+- If the sources are compiled with `_FILE_OFFSET_BITS == 64' on a 32
+- bits machine this function is available under the name `freopen'
+- and so transparently replaces the old interface.
+-
+- In some situations it is useful to know whether a given stream is
+-available for reading or writing. This information is normally not
+-available and would have to be remembered separately. Solaris
+-introduced a few functions to get this information from the stream
+-descriptor and these functions are also available in the GNU C library.
+-
+- - Function: int __freadable (FILE *STREAM)
+- The `__freadable' function determines whether the stream STREAM
+- was opened to allow reading. In this case the return value is
+- nonzero. For write-only streams the function returns zero.
+-
+- This function is declared in `stdio_ext.h'.
+-
+- - Function: int __fwritable (FILE *STREAM)
+- The `__fwritable' function determines whether the stream STREAM
+- was opened to allow writing. In this case the return value is
+- nonzero. For read-only streams the function returns zero.
+-
+- This function is declared in `stdio_ext.h'.
+-
+- For slightly different kind of problems there are two more functions.
+-They provide even finer-grained information.
+-
+- - Function: int __freading (FILE *STREAM)
+- The `__freading' function determines whether the stream STREAM was
+- last read from or whether it is opened read-only. In this case
+- the return value is nonzero, otherwise it is zero. Determining
+- whether a stream opened for reading and writing was last used for
+- writing allows to draw conclusions about the content about the
+- buffer, among other things.
+-
+- This function is declared in `stdio_ext.h'.
+-
+- - Function: int __fwriting (FILE *STREAM)
+- The `__fwriting' function determines whether the stream STREAM was
+- last written to or whether it is opened write-only. In this case
+- the return value is nonzero, otherwise it is zero.
+-
+- This function is declared in `stdio_ext.h'.

+-
+-Closing Streams
+-===============
+-
+- When a stream is closed with `fclose', the connection between the
+-stream and the file is canceled. After you have closed a stream, you
+-cannot perform any additional operations on it.
+-
+- - Function: int fclose (FILE *STREAM)
+- This function causes STREAM to be closed and the connection to the
+- corresponding file to be broken. Any buffered output is written
+- and any buffered input is discarded. The `fclose' function returns
+- a value of `0' if the file was closed successfully, and `EOF' if
+- an error was detected.
+-
+- It is important to check for errors when you call `fclose' to close
+- an output stream, because real, everyday errors can be detected at
+- this time. For example, when `fclose' writes the remaining
+- buffered output, it might get an error because the disk is full.
+- Even if you know the buffer is empty, errors can still occur when
+- closing a file if you are using NFS.
+-
+- The function `fclose' is declared in `stdio.h'.
+-
+- To close all streams currently available the GNU C Library provides
+-another function.
+-
+- - Function: int fcloseall (void)
+- This function causes all open streams of the process to be closed
+- and the connection to corresponding files to be broken. All
+- buffered data is written and any buffered input is discarded. The
+- `fcloseall' function returns a value of `0' if all the files were
+- closed successfully, and `EOF' if an error was detected.
+-
+- This function should be used only in special situations, e.g.,
+- when an error occurred and the program must be aborted. Normally
+- each single stream should be closed separately so that problems
+- with individual streams can be identified. It is also problematic
+- since the standard streams (*note Standard Streams::) will also be
+- closed.
+-
+- The function `fcloseall' is declared in `stdio.h'.
+-
+- If the `main' function to your program returns, or if you call the
+-`exit' function (*note Normal Termination::), all open streams are
+-automatically closed properly. If your program terminates in any other
+-manner, such as by calling the `abort' function (*note Aborting a
+-Program::) or from a fatal signal (*note Signal Handling::), open
+-streams might not be closed properly. Buffered output might not be
+-flushed and files may be incomplete. For more information on buffering
+-of streams, see *Note Stream Buffering::.

+-Streams and Threads
+-===================
+-
+- Streams can be used in multi-threaded applications in the same way
+-they are used in single-threaded applications. But the programmer must
+-be aware of a the possible complications. It is important to know about
+-these also if the program one writes never use threads since the design
+-and implementation of many stream functions is heavily influenced by the
+-requirements added by multi-threaded programming.
+-
+- The POSIX standard requires that by default the stream operations are
+-atomic. I.e., issuing two stream operations for the same stream in two
+-threads at the same time will cause the operations to be executed as if
+-they were issued sequentially. The buffer operations performed while
+-reading or writing are protected from other uses of the same stream. To
+-do this each stream has an internal lock object which has to be
+-(implicitly) acquired before any work can be done.
+-
+- But there are situations where this is not enough and there are also
+-situations where this is not wanted. The implicit locking is not enough
+-if the program requires more than one stream function call to happen
+-atomically. One example would be if an output line a program wants to
+-generate is created by several function calls. The functions by
+-themselves would ensure only atomicity of their own operation, but not
+-atomicity over all the function calls. For this it is necessary to
+-perform the stream locking in the application code.
+-
+- - Function: void flockfile (FILE *STREAM)
+- The `flockfile' function acquires the internal locking object
+- associated with the stream STREAM. This ensures that no other
+- thread can explicitly through `flockfile'/`ftrylockfile' or
+- implicit through a call of a stream function lock the stream. The
+- thread will block until the lock is acquired. An explicit call to
+- `funlockfile' has to be used to release the lock.
+-
+- - Function: int ftrylockfile (FILE *STREAM)
+- The `ftrylockfile' function tries to acquire the internal locking
+- object associated with the stream STREAM just like `flockfile'.
+- But unlike `flockfile' this function does not block if the lock is
+- not available. `ftrylockfile' returns zero if the lock was
+- successfully acquired. Otherwise the stream is locked by another
+- thread.
+-
+- - Function: void funlockfile (FILE *STREAM)
+- The `funlockfile' function releases the internal locking object of
+- the stream STREAM. The stream must have been locked before by a
+- call to `flockfile' or a successful call of `ftrylockfile'. The
+- implicit locking performed by the stream operations do not count.
+- The `funlockfile' function does not return an error status and the
+- behavior of a call for a stream which is not locked by the current
+- thread is undefined.
+-
+- The following example shows how the functions above can be used to
+-generate an output line atomically even in multi-threaded applications
+-(yes, the same job could be done with one `fprintf' call but it is
+-sometimes not possible):
+-
+- FILE *fp;
+- {
+- ...
+- flockfile (fp);
+- fputs ("This is test number ", fp);
+- fprintf (fp, "%d\n", test);
+- funlockfile (fp)
+- }
+-
+- Without the explicit locking it would be possible for another thread
+-to use the stream FP after the `fputs' call return and before `fprintf'
+-was called with the result that the number does not follow the word
+-`number'.
+-
+- From this description it might already be clear that the locking
+-objects in streams are no simple mutexes. Since locking the same
+-stream twice in the same thread is allowed the locking objects must be
+-equivalent to recursive mutexes. These mutexes keep track of the owner
+-and the number of times the lock is acquired. The same number of
+-`funlockfile' calls by the same threads is necessary to unlock the
+-stream completely. For instance:
+-
+- void
+- foo (FILE *fp)
+- {
+- ftrylockfile (fp);
+- fputs ("in foo\n", fp);
+- /* This is very wrong!!! */
+- funlockfile (fp);
+- }
+-
+- It is important here that the `funlockfile' function is only called
+-if the `ftrylockfile' function succeeded in locking the stream. It is
+-therefore always wrong to ignore the result of `ftrylockfile'. And it
+-makes no sense since otherwise one would use `flockfile'. The result
+-of code like that above is that either `funlockfile' tries to free a
+-stream that hasn't been locked by the current thread or it frees the
+-stream prematurely. The code should look like this:
+-
+- void
+- foo (FILE *fp)
+- {
+- if (ftrylockfile (fp) == 0)
+- {
+- fputs ("in foo\n", fp);
+- funlockfile (fp);
+- }
+- }
+-
+- Now that we covered why it is necessary to have these locking it is
+-necessary to talk about situations when locking is unwanted and what can
+-be done. The locking operations (explicit or implicit) don't come for
+-free. Even if a lock is not taken the cost is not zero. The operations
+-which have to be performed require memory operations that are safe in
+-multi-processor environments. With the many local caches involved in
+-such systems this is quite costly. So it is best to avoid the locking
+-completely if it is not needed - because the code in question is never
+-used in a context where two or more threads may use a stream at a time.
+-This can be determined most of the time for application code; for
+-library code which can be used in many contexts one should default to be
+-conservative and use locking.
+-
+- There are two basic mechanisms to avoid locking. The first is to use
+-the `_unlocked' variants of the stream operations. The POSIX standard
+-defines quite a few of those and the GNU library adds a few more.
+-These variants of the functions behave just like the functions with the
+-name without the suffix except that they do not lock the stream. Using
+-these functions is very desirable since they are potentially much
+-faster. This is not only because the locking operation itself is
+-avoided. More importantly, functions like `putc' and `getc' are very
+-simple and traditionally (before the introduction of threads) were
+-implemented as macros which are very fast if the buffer is not empty.
+-With the addition of locking requirements these functions are no longer
+-implemented as macros since they would would expand to too much code.
+-But these macros are still available with the same functionality under
+-the new names `putc_unlocked' and `getc_unlocked'. This possibly huge
+-difference of speed also suggests the use of the `_unlocked' functions
+-even if locking is required. The difference is that the locking then
+-has to be performed in the program:
+-
+- void
+- foo (FILE *fp, char *buf)
+- {
+- flockfile (fp);
+- while (*buf != '/')
+- putc_unlocked (*buf++, fp);
+- funlockfile (fp);
+- }
+-
+- If in this example the `putc' function would be used and the
+-explicit locking would be missing the `putc' function would have to
+-acquire the lock in every call, potentially many times depending on when
+-the loop terminates. Writing it the way illustrated above allows the
+-`putc_unlocked' macro to be used which means no locking and direct
+-manipulation of the buffer of the stream.
+-
+- A second way to avoid locking is by using a non-standard function
+-which was introduced in Solaris and is available in the GNU C library
+-as well.
+-
+- - Function: int __fsetlocking (FILE *STREAM, int TYPE)
+- The `__fsetlocking' function can be used to select whether the
+- stream operations will implicitly acquire the locking object of the
+- stream STREAM. By default this is done but it can be disabled and
+- reinstated using this function. There are three values defined
+- for the TYPE parameter.
+-
+- `FSETLOCKING_INTERNAL'
+- The stream `stream' will from now on use the default internal
+- locking. Every stream operation with exception of the
+- `_unlocked' variants will implicitly lock the stream.
+-
+- `FSETLOCKING_BYCALLER'
+- After the `__fsetlocking' function returns the user is
+- responsible for locking the stream. None of the stream
+- operations will implicitly do this anymore until the state is
+- set back to `FSETLOCKING_INTERNAL'.
+-
+- `FSETLOCKING_QUERY'
+- `__fsetlocking' only queries the current locking state of the
+- stream. The return value will be `FSETLOCKING_INTERNAL' or
+- `FSETLOCKING_BYCALLER' depending on the state.
+-
+- The return value of `__fsetlocking' is either
+- `FSETLOCKING_INTERNAL' or `FSETLOCKING_BYCALLER' depending on the
+- state of the stream before the call.
+-
+- This function and the values for the TYPE parameter are declared
+- in `stdio_ext.h'.
+-
+- This function is especially useful when program code has to be used
+-which is written without knowledge about the `_unlocked' functions (or
+-if the programmer was too lazy to use them).

+-
+-Streams in Internationalized Applications
+-=========================================
+-
+- ISO C90 introduced the new type `wchar_t' to allow handling larger
+-character sets. What was missing was a possibility to output strings
+-of `wchar_t' directly. One had to convert them into multibyte strings
+-using `mbstowcs' (there was no `mbsrtowcs' yet) and then use the normal
+-stream functions. While this is doable it is very cumbersome since
+-performing the conversions is not trivial and greatly increases program
+-complexity and size.
+-
+- The Unix standard early on (I think in XPG4.2) introduced two
+-additional format specifiers for the `printf' and `scanf' families of
+-functions. Printing and reading of single wide characters was made
+-possible using the `%C' specifier and wide character strings can be
+-handled with `%S'. These modifiers behave just like `%c' and `%s' only
+-that they expect the corresponding argument to have the wide character
+-type and that the wide character and string are transformed into/from
+-multibyte strings before being used.
+-
+- This was a beginning but it is still not good enough. Not always is
+-it desirable to use `printf' and `scanf'. The other, smaller and
+-faster functions cannot handle wide characters. Second, it is not
+-possible to have a format string for `printf' and `scanf' consisting of
+-wide characters. The result is that format strings would have to be
+-generated if they have to contain non-basic characters.
+-
+- In the Amendment 1 to ISO C90 a whole new set of functions was added
+-to solve the problem. Most of the stream functions got a counterpart
+-which take a wide character or wide character string instead of a
+-character or string respectively. The new functions operate on the
+-same streams (like `stdout'). This is different from the model of the
+-C++ runtime library where separate streams for wide and normal I/O are
+-used.
+-
+- Being able to use the same stream for wide and normal operations
+-comes with a restriction: a stream can be used either for wide
+-operations or for normal operations. Once it is decided there is no
+-way back. Only a call to `freopen' or `freopen64' can reset the
+-"orientation". The orientation can be decided in three ways:
+-
+- * If any of the normal character functions is used (this includes the
+- `fread' and `fwrite' functions) the stream is marked as not wide
+- oriented.
+-
+- * If any of the wide character functions is used the stream is
+- marked as wide oriented.
+-
+- * The `fwide' function can be used to set the orientation either way.
+-
+- It is important to never mix the use of wide and not wide operations
+-on a stream. There are no diagnostics issued. The application behavior
+-will simply be strange or the application will simply crash. The
+-`fwide' function can help avoiding this.
+-
+- - Function: int fwide (FILE *STREAM, int MODE)
+- The `fwide' function can be used to set and query the state of the
+- orientation of the stream STREAM. If the MODE parameter has a
+- positive value the streams get wide oriented, for negative values
+- narrow oriented. It is not possible to overwrite previous
+- orientations with `fwide'. I.e., if the stream STREAM was already
+- oriented before the call nothing is done.
+-
+- If MODE is zero the current orientation state is queried and
+- nothing is changed.
+-
+- The `fwide' function returns a negative value, zero, or a positive
+- value if the stream is narrow, not at all, or wide oriented
+- respectively.
+-
+- This function was introduced in Amendment 1 to ISO C90 and is
+- declared in `wchar.h'.
+-
+- It is generally a good idea to orient a stream as early as possible.
+-This can prevent surprise especially for the standard streams `stdin',
+-`stdout', and `stderr'. If some library function in some situations
+-uses one of these streams and this use orients the stream in a
+-different way the rest of the application expects it one might end up
+-with hard to reproduce errors. Remember that no errors are signal if
+-the streams are used incorrectly. Leaving a stream unoriented after
+-creation is normally only necessary for library functions which create
+-streams which can be used in different contexts.
+-
+- When writing code which uses streams and which can be used in
+-different contexts it is important to query the orientation of the
+-stream before using it (unless the rules of the library interface
+-demand a specific orientation). The following little, silly function
+-illustrates this.
+-
+- void
+- print_f (FILE *fp)
+- {
+- if (fwide (fp, 0) > 0)
+- /* Positive return value means wide orientation. */
+- fputwc (L'f', fp);
+- else
+- fputc ('f', fp);
+- }
+-
+- Note that in this case the function `print_f' decides about the
+-orientation of the stream if it was unoriented before (will not happen
+-if the advise above is followed).
+-
+- The encoding used for the `wchar_t' values is unspecified and the
+-user must not make any assumptions about it. For I/O of `wchar_t'
+-values this means that it is impossible to write these values directly
+-to the stream. This is not what follows from the ISO C locale model
+-either. What happens instead is that the bytes read from or written to
+-the underlying media are first converted into the internal encoding
+-chosen by the implementation for `wchar_t'. The external encoding is
+-determined by the `LC_CTYPE' category of the current locale or by the
+-`ccs' part of the mode specification given to `fopen', `fopen64',
+-`freopen', or `freopen64'. How and when the conversion happens is
+-unspecified and it happens invisible to the user.
+-
+- Since a stream is created in the unoriented state it has at that
+-point no conversion associated with it. The conversion which will be
+-used is determined by the `LC_CTYPE' category selected at the time the
+-stream is oriented. If the locales are changed at the runtime this
+-might produce surprising results unless one pays attention. This is
+-just another good reason to orient the stream explicitly as soon as
+-possible, perhaps with a call to `fwide'.

+-Simple Output by Characters or Lines
+-====================================
+-
+- This section describes functions for performing character- and
+-line-oriented output.
+-
+- These narrow streams functions are declared in the header file
+-`stdio.h' and the wide stream functions in `wchar.h'.
+-
+- - Function: int fputc (int C, FILE *STREAM)
+- The `fputc' function converts the character C to type `unsigned
+- char', and writes it to the stream STREAM. `EOF' is returned if a
+- write error occurs; otherwise the character C is returned.
+-
+- - Function: wint_t fputwc (wchar_t WC, FILE *STREAM)
+- The `fputwc' function writes the wide character WC to the stream
+- STREAM. `WEOF' is returned if a write error occurs; otherwise the
+- character WC is returned.
+-
+- - Function: int fputc_unlocked (int C, FILE *STREAM)
+- The `fputc_unlocked' function is equivalent to the `fputc'
+- function except that it does not implicitly lock the stream.
+-
+- - Function: wint_t fputwc_unlocked (wint_t WC, FILE *STREAM)
+- The `fputwc_unlocked' function is equivalent to the `fputwc'
+- function except that it does not implicitly lock the stream.
+-
+- This function is a GNU extension.
+-
+- - Function: int putc (int C, FILE *STREAM)
+- This is just like `fputc', except that most systems implement it as
+- a macro, making it faster. One consequence is that it may
+- evaluate the STREAM argument more than once, which is an exception
+- to the general rule for macros. `putc' is usually the best
+- function to use for writing a single character.
+-
+- - Function: wint_t putwc (wchar_t WC, FILE *STREAM)
+- This is just like `fputwc', except that it can be implement as a
+- macro, making it faster. One consequence is that it may evaluate
+- the STREAM argument more than once, which is an exception to the
+- general rule for macros. `putwc' is usually the best function to
+- use for writing a single wide character.
+-
+- - Function: int putc_unlocked (int C, FILE *STREAM)
+- The `putc_unlocked' function is equivalent to the `putc' function
+- except that it does not implicitly lock the stream.
+-
+- - Function: wint_t putwc_unlocked (wchar_t WC, FILE *STREAM)
+- The `putwc_unlocked' function is equivalent to the `putwc'
+- function except that it does not implicitly lock the stream.
+-
+- This function is a GNU extension.
+-
+- - Function: int putchar (int C)
+- The `putchar' function is equivalent to `putc' with `stdout' as
+- the value of the STREAM argument.
+-
+- - Function: wint_t putwchar (wchar_t WC)
+- The `putwchar' function is equivalent to `putwc' with `stdout' as
+- the value of the STREAM argument.
+-
+- - Function: int putchar_unlocked (int C)
+- The `putchar_unlocked' function is equivalent to the `putchar'
+- function except that it does not implicitly lock the stream.
+-
+- - Function: wint_t putwchar_unlocked (wchar_t WC)
+- The `putwchar_unlocked' function is equivalent to the `putwchar'
+- function except that it does not implicitly lock the stream.
+-
+- This function is a GNU extension.
+-
+- - Function: int fputs (const char *S, FILE *STREAM)
+- The function `fputs' writes the string S to the stream STREAM.
+- The terminating null character is not written. This function does
+- _not_ add a newline character, either. It outputs only the
+- characters in the string.
+-
+- This function returns `EOF' if a write error occurs, and otherwise
+- a non-negative value.
+-
+- For example:
+-
+- fputs ("Are ", stdout);
+- fputs ("you ", stdout);
+- fputs ("hungry?\n", stdout);
+-
+- outputs the text `Are you hungry?' followed by a newline.
+-
+- - Function: int fputws (const wchar_t *WS, FILE *STREAM)
+- The function `fputws' writes the wide character string WS to the
+- stream STREAM. The terminating null character is not written.
+- This function does _not_ add a newline character, either. It
+- outputs only the characters in the string.
+-
+- This function returns `WEOF' if a write error occurs, and otherwise
+- a non-negative value.
+-
+- - Function: int fputs_unlocked (const char *S, FILE *STREAM)
+- The `fputs_unlocked' function is equivalent to the `fputs'
+- function except that it does not implicitly lock the stream.
+-
+- This function is a GNU extension.
+-
+- - Function: int fputws_unlocked (const wchar_t *WS, FILE *STREAM)
+- The `fputws_unlocked' function is equivalent to the `fputws'
+- function except that it does not implicitly lock the stream.
+-
+- This function is a GNU extension.
+-
+- - Function: int puts (const char *S)
+- The `puts' function writes the string S to the stream `stdout'
+- followed by a newline. The terminating null character of the
+- string is not written. (Note that `fputs' does _not_ write a
+- newline as this function does.)
+-
+- `puts' is the most convenient function for printing simple
+- messages. For example:
+-
+- puts ("This is a message.");
+-
+- outputs the text `This is a message.' followed by a newline.
+-
+- - Function: int putw (int W, FILE *STREAM)
+- This function writes the word W (that is, an `int') to STREAM. It
+- is provided for compatibility with SVID, but we recommend you use
+- `fwrite' instead (*note Block Input/Output::).

+-Character Input
+-===============
+-
+- This section describes functions for performing character-oriented
+-input. These narrow streams functions are declared in the header file
+-`stdio.h' and the wide character functions are declared in `wchar.h'.
+-
+- These functions return an `int' or `wint_t' value (for narrow and
+-wide stream functions respectively) that is either a character of
+-input, or the special value `EOF'/`WEOF' (usually -1). For the narrow
+-stream functions it is important to store the result of these functions
+-in a variable of type `int' instead of `char', even when you plan to
+-use it only as a character. Storing `EOF' in a `char' variable
+-truncates its value to the size of a character, so that it is no longer
+-distinguishable from the valid character `(char) -1'. So always use an
+-`int' for the result of `getc' and friends, and check for `EOF' after
+-the call; once you've verified that the result is not `EOF', you can be
+-sure that it will fit in a `char' variable without loss of information.
+-
+- - Function: int fgetc (FILE *STREAM)
+- This function reads the next character as an `unsigned char' from
+- the stream STREAM and returns its value, converted to an `int'.
+- If an end-of-file condition or read error occurs, `EOF' is
+- returned instead.
+-
+- - Function: wint_t fgetwc (FILE *STREAM)
+- This function reads the next wide character from the stream STREAM
+- and returns its value. If an end-of-file condition or read error
+- occurs, `WEOF' is returned instead.
+-
+- - Function: int fgetc_unlocked (FILE *STREAM)
+- The `fgetc_unlocked' function is equivalent to the `fgetc'
+- function except that it does not implicitly lock the stream.
+-
+- - Function: wint_t fgetwc_unlocked (FILE *STREAM)
+- The `fgetwc_unlocked' function is equivalent to the `fgetwc'
+- function except that it does not implicitly lock the stream.
+-
+- This function is a GNU extension.
+-
+- - Function: int getc (FILE *STREAM)
+- This is just like `fgetc', except that it is permissible (and
+- typical) for it to be implemented as a macro that evaluates the
+- STREAM argument more than once. `getc' is often highly optimized,
+- so it is usually the best function to use to read a single
+- character.
+-
+- - Function: wint_t getwc (FILE *STREAM)
+- This is just like `fgetwc', except that it is permissible for it to
+- be implemented as a macro that evaluates the STREAM argument more
+- than once. `getwc' can be highly optimized, so it is usually the
+- best function to use to read a single wide character.
+-
+- - Function: int getc_unlocked (FILE *STREAM)
+- The `getc_unlocked' function is equivalent to the `getc' function
+- except that it does not implicitly lock the stream.
+-
+- - Function: wint_t getwc_unlocked (FILE *STREAM)
+- The `getwc_unlocked' function is equivalent to the `getwc'
+- function except that it does not implicitly lock the stream.
+-
+- This function is a GNU extension.
+-
+- - Function: int getchar (void)
+- The `getchar' function is equivalent to `getc' with `stdin' as the
+- value of the STREAM argument.
+-
+- - Function: wint_t getwchar (void)
+- The `getwchar' function is equivalent to `getwc' with `stdin' as
+- the value of the STREAM argument.
+-
+- - Function: int getchar_unlocked (void)
+- The `getchar_unlocked' function is equivalent to the `getchar'
+- function except that it does not implicitly lock the stream.
+-
+- - Function: wint_t getwchar_unlocked (void)
+- The `getwchar_unlocked' function is equivalent to the `getwchar'
+- function except that it does not implicitly lock the stream.
+-
+- This function is a GNU extension.
+-
+- Here is an example of a function that does input using `fgetc'. It
+-would work just as well using `getc' instead, or using `getchar ()'
+-instead of `fgetc (stdin)'. The code would also work the same for the
+-wide character stream functions.
+-
+- int
+- y_or_n_p (const char *question)
+- {
+- fputs (question, stdout);
+- while (1)
+- {
+- int c, answer;
+- /* Write a space to separate answer from question. */
+- fputc (' ', stdout);
+- /* Read the first character of the line.
+- This should be the answer character, but might not be. */
+- c = tolower (fgetc (stdin));
+- answer = c;
+- /* Discard rest of input line. */
+- while (c != '\n' && c != EOF)
+- c = fgetc (stdin);
+- /* Obey the answer if it was valid. */
+- if (answer == 'y')
+- return 1;
+- if (answer == 'n')
+- return 0;
+- /* Answer was invalid: ask for valid answer. */
+- fputs ("Please answer y or n:", stdout);
+- }
+- }
+-
+- - Function: int getw (FILE *STREAM)
+- This function reads a word (that is, an `int') from STREAM. It's
+- provided for compatibility with SVID. We recommend you use
+- `fread' instead (*note Block Input/Output::). Unlike `getc', any
+- `int' value could be a valid result. `getw' returns `EOF' when it
+- encounters end-of-file or an error, but there is no way to
+- distinguish this from an input word with value -1.

+-
+-Line-Oriented Input
+-===================
+-
+- Since many programs interpret input on the basis of lines, it is
+-convenient to have functions to read a line of text from a stream.
+-
+- Standard C has functions to do this, but they aren't very safe: null
+-characters and even (for `gets') long lines can confuse them. So the
+-GNU library provides the nonstandard `getline' function that makes it
+-easy to read lines reliably.
+-
+- Another GNU extension, `getdelim', generalizes `getline'. It reads
+-a delimited record, defined as everything through the next occurrence
+-of a specified delimiter character.
+-
+- All these functions are declared in `stdio.h'.
+-
+- - Function: ssize_t getline (char **LINEPTR, size_t *N, FILE *STREAM)
+- This function reads an entire line from STREAM, storing the text
+- (including the newline and a terminating null character) in a
+- buffer and storing the buffer address in `*LINEPTR'.
+-
+- Before calling `getline', you should place in `*LINEPTR' the
+- address of a buffer `*N' bytes long, allocated with `malloc'. If
+- this buffer is long enough to hold the line, `getline' stores the
+- line in this buffer. Otherwise, `getline' makes the buffer bigger
+- using `realloc', storing the new buffer address back in `*LINEPTR'
+- and the increased size back in `*N'. *Note Unconstrained
+- Allocation::.
+-
+- If you set `*LINEPTR' to a null pointer, and `*N' to zero, before
+- the call, then `getline' allocates the initial buffer for you by
+- calling `malloc'.
+-
+- In either case, when `getline' returns, `*LINEPTR' is a `char *'
+- which points to the text of the line.
+-
+- When `getline' is successful, it returns the number of characters
+- read (including the newline, but not including the terminating
+- null). This value enables you to distinguish null characters that
+- are part of the line from the null character inserted as a
+- terminator.
+-
+- This function is a GNU extension, but it is the recommended way to
+- read lines from a stream. The alternative standard functions are
+- unreliable.
+-
+- If an error occurs or end of file is reached without any bytes
+- read, `getline' returns `-1'.
+-
+- - Function: ssize_t getdelim (char **LINEPTR, size_t *N, int
+- DELIMITER, FILE *STREAM)
+- This function is like `getline' except that the character which
+- tells it to stop reading is not necessarily newline. The argument
+- DELIMITER specifies the delimiter character; `getdelim' keeps
+- reading until it sees that character (or end of file).
+-
+- The text is stored in LINEPTR, including the delimiter character
+- and a terminating null. Like `getline', `getdelim' makes LINEPTR
+- bigger if it isn't big enough.
+-
+- `getline' is in fact implemented in terms of `getdelim', just like
+- this:
+-
+- ssize_t
+- getline (char **lineptr, size_t *n, FILE *stream)
+- {
+- return getdelim (lineptr, n, '\n', stream);
+- }
+-
+- - Function: char * fgets (char *S, int COUNT, FILE *STREAM)
+- The `fgets' function reads characters from the stream STREAM up to
+- and including a newline character and stores them in the string S,
+- adding a null character to mark the end of the string. You must
+- supply COUNT characters worth of space in S, but the number of
+- characters read is at most COUNT - 1. The extra character space
+- is used to hold the null character at the end of the string.
+-
+- If the system is already at end of file when you call `fgets', then
+- the contents of the array S are unchanged and a null pointer is
+- returned. A null pointer is also returned if a read error occurs.
+- Otherwise, the return value is the pointer S.
+-
+- *Warning:* If the input data has a null character, you can't tell.
+- So don't use `fgets' unless you know the data cannot contain a
+- null. Don't use it to read files edited by the user because, if
+- the user inserts a null character, you should either handle it
+- properly or print a clear error message. We recommend using
+- `getline' instead of `fgets'.
+-
+- - Function: wchar_t * fgetws (wchar_t *WS, int COUNT, FILE *STREAM)
+- The `fgetws' function reads wide characters from the stream STREAM
+- up to and including a newline character and stores them in the
+- string WS, adding a null wide character to mark the end of the
+- string. You must supply COUNT wide characters worth of space in
+- WS, but the number of characters read is at most COUNT - 1. The
+- extra character space is used to hold the null wide character at
+- the end of the string.
+-
+- If the system is already at end of file when you call `fgetws',
+- then the contents of the array WS are unchanged and a null pointer
+- is returned. A null pointer is also returned if a read error
+- occurs. Otherwise, the return value is the pointer WS.
+-
+- *Warning:* If the input data has a null wide character (which are
+- null bytes in the input stream), you can't tell. So don't use
+- `fgetws' unless you know the data cannot contain a null. Don't use
+- it to read files edited by the user because, if the user inserts a
+- null character, you should either handle it properly or print a
+- clear error message.
+-
+- - Function: char * fgets_unlocked (char *S, int COUNT, FILE *STREAM)
+- The `fgets_unlocked' function is equivalent to the `fgets'
+- function except that it does not implicitly lock the stream.
+-
+- This function is a GNU extension.
+-
+- - Function: wchar_t * fgetws_unlocked (wchar_t *WS, int COUNT, FILE
+- *STREAM)
+- The `fgetws_unlocked' function is equivalent to the `fgetws'
+- function except that it does not implicitly lock the stream.
+-
+- This function is a GNU extension.
+-
+- - Deprecated function: char * gets (char *S)
+- The function `gets' reads characters from the stream `stdin' up to
+- the next newline character, and stores them in the string S. The
+- newline character is discarded (note that this differs from the
+- behavior of `fgets', which copies the newline character into the
+- string). If `gets' encounters a read error or end-of-file, it
+- returns a null pointer; otherwise it returns S.
+-
+- *Warning:* The `gets' function is *very dangerous* because it
+- provides no protection against overflowing the string S. The GNU
+- library includes it for compatibility only. You should *always*
+- use `fgets' or `getline' instead. To remind you of this, the
+- linker (if using GNU `ld') will issue a warning whenever you use
+- `gets'.

+-
+-Unreading
+-=========
+-
+- In parser programs it is often useful to examine the next character
+-in the input stream without removing it from the stream. This is called
+-"peeking ahead" at the input because your program gets a glimpse of the
+-input it will read next.
+-
+- Using stream I/O, you can peek ahead at input by first reading it and
+-then "unreading" it (also called "pushing it back" on the stream).
+-Unreading a character makes it available to be input again from the
+-stream, by the next call to `fgetc' or other input function on that
+-stream.

+-

+-File: libc.info, Node: Unreading Idea, Next: How Unread, Up: Unreading
+-
+-What Unreading Means
+---------------------
+-
+- Here is a pictorial explanation of unreading. Suppose you have a
+-stream reading a file that contains just six characters, the letters
+-`foobar'. Suppose you have read three characters so far. The
+-situation looks like this:
+-
+- f o o b a r
+- ^
+-
+-so the next input character will be `b'.
+-
+- If instead of reading `b' you unread the letter `o', you get a
+-situation like this:
+-
+- f o o b a r
+- |
+- o--
+- ^
+-
+-so that the next input characters will be `o' and `b'.
+-
+- If you unread `9' instead of `o', you get this situation:
+-
+- f o o b a r
+- |
+- 9--
+- ^
+-
+-so that the next input characters will be `9' and `b'.
+-
+-\1f
+-File: libc.info, Node: How Unread, Prev: Unreading Idea, Up: Unreading
+-
+-Using `ungetc' To Do Unreading
+-------------------------------
+-
+- The function to unread a character is called `ungetc', because it
+-reverses the action of `getc'.
+-
+- - Function: int ungetc (int C, FILE *STREAM)
+- The `ungetc' function pushes back the character C onto the input
+- stream STREAM. So the next input from STREAM will read C before
+- anything else.
+-
+- If C is `EOF', `ungetc' does nothing and just returns `EOF'. This
+- lets you call `ungetc' with the return value of `getc' without
+- needing to check for an error from `getc'.
+-
+- The character that you push back doesn't have to be the same as
+- the last character that was actually read from the stream. In
+- fact, it isn't necessary to actually read any characters from the
+- stream before unreading them with `ungetc'! But that is a strange
+- way to write a program; usually `ungetc' is used only to unread a
+- character that was just read from the same stream. The GNU C
+- library supports this even on files opened in binary mode, but
+- other systems might not.
+-
+- The GNU C library only supports one character of pushback--in other
+- words, it does not work to call `ungetc' twice without doing input
+- in between. Other systems might let you push back multiple
+- characters; then reading from the stream retrieves the characters
+- in the reverse order that they were pushed.
+-
+- Pushing back characters doesn't alter the file; only the internal
+- buffering for the stream is affected. If a file positioning
+- function (such as `fseek', `fseeko' or `rewind'; *note File
+- Positioning::) is called, any pending pushed-back characters are
+- discarded.
+-
+- Unreading a character on a stream that is at end of file clears the
+- end-of-file indicator for the stream, because it makes the
+- character of input available. After you read that character,
+- trying to read again will encounter end of file.
+-
+- - Function: wint_t ungetwc (wint_t WC, FILE *STREAM)
+- The `ungetwc' function behaves just like `ungetc' just that it
+- pushes back a wide character.
+-
+- Here is an example showing the use of `getc' and `ungetc' to skip
+-over whitespace characters. When this function reaches a
+-non-whitespace character, it unreads that character to be seen again on
+-the next read operation on the stream.
+-
+- #include <stdio.h>
+- #include <ctype.h>
+-
+- void
+- skip_whitespace (FILE *stream)
+- {
+- int c;
+- do
+- /* No need to check for `EOF' because it is not
+- `isspace', and `ungetc' ignores `EOF'. */
+- c = getc (stream);
+- while (isspace (c));

+-Block Input/Output
+-==================
+-
+- This section describes how to do input and output operations on
+-blocks of data. You can use these functions to read and write binary
+-data, as well as to read and write text in fixed-size blocks instead of
+-by characters or lines.
+-
+- Binary files are typically used to read and write blocks of data in
+-the same format as is used to represent the data in a running program.
+-In other words, arbitrary blocks of memory--not just character or string
+-objects--can be written to a binary file, and meaningfully read in
+-again by the same program.
+-
+- Storing data in binary form is often considerably more efficient than
+-using the formatted I/O functions. Also, for floating-point numbers,
+-the binary form avoids possible loss of precision in the conversion
+-process. On the other hand, binary files can't be examined or modified
+-easily using many standard file utilities (such as text editors), and
+-are not portable between different implementations of the language, or
+-different kinds of computers.
+-
+- These functions are declared in `stdio.h'.
+-
+- - Function: size_t fread (void *DATA, size_t SIZE, size_t COUNT, FILE
+- *STREAM)
+- This function reads up to COUNT objects of size SIZE into the
+- array DATA, from the stream STREAM. It returns the number of
+- objects actually read, which might be less than COUNT if a read
+- error occurs or the end of the file is reached. This function
+- returns a value of zero (and doesn't read anything) if either SIZE
+- or COUNT is zero.
+-
+- If `fread' encounters end of file in the middle of an object, it
+- returns the number of complete objects read, and discards the
+- partial object. Therefore, the stream remains at the actual end
+- of the file.
+-
+- - Function: size_t fread_unlocked (void *DATA, size_t SIZE, size_t
+- COUNT, FILE *STREAM)
+- The `fread_unlocked' function is equivalent to the `fread'
+- function except that it does not implicitly lock the stream.
+-
+- This function is a GNU extension.
+-
+- - Function: size_t fwrite (const void *DATA, size_t SIZE, size_t
+- COUNT, FILE *STREAM)
+- This function writes up to COUNT objects of size SIZE from the
+- array DATA, to the stream STREAM. The return value is normally
+- COUNT, if the call succeeds. Any other value indicates some sort
+- of error, such as running out of space.
+-
+- - Function: size_t fwrite_unlocked (const void *DATA, size_t SIZE,
+- size_t COUNT, FILE *STREAM)
+- The `fwrite_unlocked' function is equivalent to the `fwrite'
+- function except that it does not implicitly lock the stream.

+-================
+-
+- The functions described in this section (`printf' and related
+-functions) provide a convenient way to perform formatted output. You
+-call `printf' with a "format string" or "template string" that
+-specifies how to format the values of the remaining arguments.
+-
+- Unless your program is a filter that specifically performs line- or
+-character-oriented processing, using `printf' or one of the other
+-related functions described in this section is usually the easiest and
+-most concise way to perform output. These functions are especially
+-useful for printing error messages, tables of data, and the like.

+-Formatted Output Basics
+------------------------
+-
+- The `printf' function can be used to print any number of arguments.
+-The template string argument you supply in a call provides information
+-not only about the number of additional arguments, but also about their
+-types and what style should be used for printing them.
+-
+- Ordinary characters in the template string are simply written to the
+-output stream as-is, while "conversion specifications" introduced by a
+-`%' character in the template cause subsequent arguments to be
+-formatted and written to the output stream. For example,
+-
+- int pct = 37;
+- char filename[] = "foo.txt";
+- printf ("Processing of `%s' is %d%% finished.\nPlease be patient.\n",
+- filename, pct);
+-
+-produces output like
+-
+- Processing of `foo.txt' is 37% finished.
+- Please be patient.
+-
+- This example shows the use of the `%d' conversion to specify that an
+-`int' argument should be printed in decimal notation, the `%s'
+-conversion to specify printing of a string argument, and the `%%'
+-conversion to print a literal `%' character.
+-
+- There are also conversions for printing an integer argument as an
+-unsigned value in octal, decimal, or hexadecimal radix (`%o', `%u', or
+-`%x', respectively); or as a character value (`%c').
+-
+- Floating-point numbers can be printed in normal, fixed-point notation
+-using the `%f' conversion or in exponential notation using the `%e'
+-conversion. The `%g' conversion uses either `%e' or `%f' format,
+-depending on what is more appropriate for the magnitude of the
+-particular number.
+-
+- You can control formatting more precisely by writing "modifiers"
+-between the `%' and the character that indicates which conversion to
+-apply. These slightly alter the ordinary behavior of the conversion.
+-For example, most conversion specifications permit you to specify a
+-minimum field width and a flag indicating whether you want the result
+-left- or right-justified within the field.
+-
+- The specific flags and modifiers that are permitted and their
+-interpretation vary depending on the particular conversion. They're all
+-described in more detail in the following sections. Don't worry if this
+-all seems excessively complicated at first; you can almost always get
+-reasonable free-format output without using any of the modifiers at all.
+-The modifiers are mostly used to make the output look "prettier" in
+-tables.

+-Output Conversion Syntax
+-------------------------
+-
+- This section provides details about the precise syntax of conversion
+-specifications that can appear in a `printf' template string.
+-
+- Characters in the template string that are not part of a conversion
+-specification are printed as-is to the output stream. Multibyte
+-character sequences (*note Character Set Handling::) are permitted in a
+-template string.
+-
+- The conversion specifications in a `printf' template string have the
+-general form:
+-
+- % [ PARAM-NO $] FLAGS WIDTH [ . PRECISION ] TYPE CONVERSION
+-
+-or
+-
+- % [ PARAM-NO $] FLAGS WIDTH . * [ PARAM-NO $] TYPE CONVERSION
+-
+- For example, in the conversion specifier `%-10.8ld', the `-' is a
+-flag, `10' specifies the field width, the precision is `8', the letter
+-`l' is a type modifier, and `d' specifies the conversion style. (This
+-particular type specifier says to print a `long int' argument in
+-decimal notation, with a minimum of 8 digits left-justified in a field
+-at least 10 characters wide.)
+-
+- In more detail, output conversion specifications consist of an
+-initial `%' character followed in sequence by:
+-
+- * An optional specification of the parameter used for this format.
+- Normally the parameters to the `printf' function are assigned to
+- the formats in the order of appearance in the format string. But
+- in some situations (such as message translation) this is not
+- desirable and this extension allows an explicit parameter to be
+- specified.
+-
+- The PARAM-NO parts of the format must be integers in the range of
+- 1 to the maximum number of arguments present to the function call.
+- Some implementations limit this number to a certainly upper
+- bound. The exact limit can be retrieved by the following constant.
+-
+- - Macro: NL_ARGMAX
+- The value of `NL_ARGMAX' is the maximum value allowed for the
+- specification of an positional parameter in a `printf' call.
+- The actual value in effect at runtime can be retrieved by
+- using `sysconf' using the `_SC_NL_ARGMAX' parameter *note
+- Sysconf Definition::.
+-
+- Some system have a quite low limit such as 9 for System V
+- systems. The GNU C library has no real limit.
+-
+- If any of the formats has a specification for the parameter
+- position all of them in the format string shall have one.
+- Otherwise the behavior is undefined.
+-
+- * Zero or more "flag characters" that modify the normal behavior of
+- the conversion specification.
+-
+- * An optional decimal integer specifying the "minimum field width".
+- If the normal conversion produces fewer characters than this, the
+- field is padded with spaces to the specified width. This is a
+- _minimum_ value; if the normal conversion produces more characters
+- than this, the field is _not_ truncated. Normally, the output is
+- right-justified within the field.
+-
+- You can also specify a field width of `*'. This means that the
+- next argument in the argument list (before the actual value to be
+- printed) is used as the field width. The value must be an `int'.
+- If the value is negative, this means to set the `-' flag (see
+- below) and to use the absolute value as the field width.
+-
+- * An optional "precision" to specify the number of digits to be
+- written for the numeric conversions. If the precision is
+- specified, it consists of a period (`.') followed optionally by a
+- decimal integer (which defaults to zero if omitted).
+-
+- You can also specify a precision of `*'. This means that the next
+- argument in the argument list (before the actual value to be
+- printed) is used as the precision. The value must be an `int',
+- and is ignored if it is negative. If you specify `*' for both the
+- field width and precision, the field width argument precedes the
+- precision argument. Other C library versions may not recognize
+- this syntax.
+-
+- * An optional "type modifier character", which is used to specify the
+- data type of the corresponding argument if it differs from the
+- default type. (For example, the integer conversions assume a type
+- of `int', but you can specify `h', `l', or `L' for other integer
+- types.)
+-
+- * A character that specifies the conversion to be applied.
+-
+- The exact options that are permitted and how they are interpreted
+-vary between the different conversion specifiers. See the descriptions
+-of the individual conversions for information about the particular
+-options that they use.
+-
+- With the `-Wformat' option, the GNU C compiler checks calls to
+-`printf' and related functions. It examines the format string and
+-verifies that the correct number and types of arguments are supplied.
+-There is also a GNU C syntax to tell the compiler that a function you
+-write uses a `printf'-style format string. *Note Declaring Attributes
+-of Functions: (gcc.info)Function Attributes, for more information.

+-Table of Output Conversions
+----------------------------
+-
+- Here is a table summarizing what all the different conversions do:
+-
+-`%d', `%i'
+- Print an integer as a signed decimal number. *Note Integer
+- Conversions::, for details. `%d' and `%i' are synonymous for
+- output, but are different when used with `scanf' for input (*note

+-
+-`%o'
+- Print an integer as an unsigned octal number. *Note Integer
+- Conversions::, for details.
+-
+-`%u'
+- Print an integer as an unsigned decimal number. *Note Integer
+- Conversions::, for details.
+-
+-`%x', `%X'
+- Print an integer as an unsigned hexadecimal number. `%x' uses
+- lower-case letters and `%X' uses upper-case. *Note Integer
+- Conversions::, for details.
+-
+-`%f'
+- Print a floating-point number in normal (fixed-point) notation.
+- *Note Floating-Point Conversions::, for details.
+-
+-`%e', `%E'
+- Print a floating-point number in exponential notation. `%e' uses
+- lower-case letters and `%E' uses upper-case. *Note Floating-Point
+- Conversions::, for details.
+-
+-`%g', `%G'
+- Print a floating-point number in either normal or exponential
+- notation, whichever is more appropriate for its magnitude. `%g'
+- uses lower-case letters and `%G' uses upper-case. *Note
+- Floating-Point Conversions::, for details.
+-
+-`%a', `%A'
+- Print a floating-point number in a hexadecimal fractional notation
+- which the exponent to base 2 represented in decimal digits. `%a'
+- uses lower-case letters and `%A' uses upper-case. *Note
+- Floating-Point Conversions::, for details.
+-
+-`%c'
+- Print a single character. *Note Other Output Conversions::.
+-
+-`%C'
+- This is an alias for `%lc' which is supported for compatibility
+- with the Unix standard.
+-
+-`%s'
+- Print a string. *Note Other Output Conversions::.
+-
+-`%S'
+- This is an alias for `%ls' which is supported for compatibility
+- with the Unix standard.
+-
+-`%p'
+- Print the value of a pointer. *Note Other Output Conversions::.
+-
+-`%n'
+- Get the number of characters printed so far. *Note Other Output
+- Conversions::. Note that this conversion specification never
+- produces any output.
+-
+-`%m'
+- Print the string corresponding to the value of `errno'. (This is
+- a GNU extension.) *Note Other Output Conversions::.
+-
+-`%%'
+- Print a literal `%' character. *Note Other Output Conversions::.
+-
+- If the syntax of a conversion specification is invalid, unpredictable
+-things will happen, so don't do this. If there aren't enough function
+-arguments provided to supply values for all the conversion
+-specifications in the template string, or if the arguments are not of
+-the correct types, the results are unpredictable. If you supply more
+-arguments than conversion specifications, the extra argument values are
+-simply ignored; this is sometimes useful.

+-
+-Integer Conversions
+--------------------
+-
+- This section describes the options for the `%d', `%i', `%o', `%u',
+-`%x', and `%X' conversion specifications. These conversions print
+-integers in various formats.
+-
+- The `%d' and `%i' conversion specifications both print an `int'
+-argument as a signed decimal number; while `%o', `%u', and `%x' print
+-the argument as an unsigned octal, decimal, or hexadecimal number
+-(respectively). The `%X' conversion specification is just like `%x'
+-except that it uses the characters `ABCDEF' as digits instead of
+-`abcdef'.
+-
+- The following flags are meaningful:
+-
+-`-'
+- Left-justify the result in the field (instead of the normal
+- right-justification).
+-
+-`+'
+- For the signed `%d' and `%i' conversions, print a plus sign if the
+- value is positive.
+-
+-` '
+- For the signed `%d' and `%i' conversions, if the result doesn't
+- start with a plus or minus sign, prefix it with a space character
+- instead. Since the `+' flag ensures that the result includes a
+- sign, this flag is ignored if you supply both of them.
+-
+-`#'
+- For the `%o' conversion, this forces the leading digit to be `0',
+- as if by increasing the precision. For `%x' or `%X', this
+- prefixes a leading `0x' or `0X' (respectively) to the result.
+- This doesn't do anything useful for the `%d', `%i', or `%u'
+- conversions. Using this flag produces output which can be parsed
+- by the `strtoul' function (*note Parsing of Integers::) and
+- `scanf' with the `%i' conversion (*note Numeric Input
+- Conversions::).
+-
+-`''
+- Separate the digits into groups as specified by the locale
+- specified for the `LC_NUMERIC' category; *note General Numeric::.
+- This flag is a GNU extension.
+-
+-`0'
+- Pad the field with zeros instead of spaces. The zeros are placed
+- after any indication of sign or base. This flag is ignored if the
+- `-' flag is also specified, or if a precision is specified.
+-
+- If a precision is supplied, it specifies the minimum number of
+-digits to appear; leading zeros are produced if necessary. If you
+-don't specify a precision, the number is printed with as many digits as
+-it needs. If you convert a value of zero with an explicit precision of
+-zero, then no characters at all are produced.
+-
+- Without a type modifier, the corresponding argument is treated as an
+-`int' (for the signed conversions `%i' and `%d') or `unsigned int' (for
+-the unsigned conversions `%o', `%u', `%x', and `%X'). Recall that
+-since `printf' and friends are variadic, any `char' and `short'
+-arguments are automatically converted to `int' by the default argument
+-promotions. For arguments of other integer types, you can use these
+-modifiers:
+-
+-`hh'
+- Specifies that the argument is a `signed char' or `unsigned char',
+- as appropriate. A `char' argument is converted to an `int' or
+- `unsigned int' by the default argument promotions anyway, but the
+- `h' modifier says to convert it back to a `char' again.
+-
+- This modifier was introduced in ISO C99.
+-
+-`h'
+- Specifies that the argument is a `short int' or `unsigned short
+- int', as appropriate. A `short' argument is converted to an `int'
+- or `unsigned int' by the default argument promotions anyway, but
+- the `h' modifier says to convert it back to a `short' again.
+-
+-`j'
+- Specifies that the argument is a `intmax_t' or `uintmax_t', as
+- appropriate.
+-
+- This modifier was introduced in ISO C99.
+-
+-`l'
+- Specifies that the argument is a `long int' or `unsigned long
+- int', as appropriate. Two `l' characters is like the `L'
+- modifier, below.
+-
+- If used with `%c' or `%s' the corresponding parameter is
+- considered as a wide character or wide character string
+- respectively. This use of `l' was introduced in Amendment 1 to
+- ISO C90.
+-
+-`L'
+-`ll'
+-`q'
+- Specifies that the argument is a `long long int'. (This type is
+- an extension supported by the GNU C compiler. On systems that
+- don't support extra-long integers, this is the same as `long int'.)
+-
+- The `q' modifier is another name for the same thing, which comes
+- from 4.4 BSD; a `long long int' is sometimes called a "quad" `int'.
+-
+-`t'
+- Specifies that the argument is a `ptrdiff_t'.
+-
+- This modifier was introduced in ISO C99.
+-
+-`z'
+-`Z'
+- Specifies that the argument is a `size_t'.
+-
+- `z' was introduced in ISO C99. `Z' is a GNU extension predating
+- this addition and should not be used in new code.
+-
+- Here is an example. Using the template string:
+-
+- "|%5d|%-5d|%+5d|%+-5d|% 5d|%05d|%5.0d|%5.2d|%d|\n"
+-
+-to print numbers using the different options for the `%d' conversion
+-gives results like:
+-
+- | 0|0 | +0|+0 | 0|00000| | 00|0|
+- | 1|1 | +1|+1 | 1|00001| 1| 01|1|
+- | -1|-1 | -1|-1 | -1|-0001| -1| -01|-1|
+- |100000|100000|+100000|+100000| 100000|100000|100000|100000|100000|
+-
+- In particular, notice what happens in the last case where the number
+-is too large to fit in the minimum field width specified.
+-
+- Here are some more examples showing how unsigned integers print under
+-various format options, using the template string:
+-
+- "|%5u|%5o|%5x|%5X|%#5o|%#5x|%#5X|%#10.8x|\n"
+-
+- | 0| 0| 0| 0| 0| 0| 0| 00000000|
+- | 1| 1| 1| 1| 01| 0x1| 0X1|0x00000001|
+- |100000|303240|186a0|186A0|0303240|0x186a0|0X186A0|0x000186a0|

+-
+-Floating-Point Conversions
+---------------------------
+-
+- This section discusses the conversion specifications for
+-floating-point numbers: the `%f', `%e', `%E', `%g', and `%G'
+-conversions.
+-
+- The `%f' conversion prints its argument in fixed-point notation,
+-producing output of the form [`-']DDD`.'DDD, where the number of digits
+-following the decimal point is controlled by the precision you specify.
+-
+- The `%e' conversion prints its argument in exponential notation,
+-producing output of the form [`-']D`.'DDD`e'[`+'|`-']DD. Again, the
+-number of digits following the decimal point is controlled by the
+-precision. The exponent always contains at least two digits. The `%E'
+-conversion is similar but the exponent is marked with the letter `E'
+-instead of `e'.
+-
+- The `%g' and `%G' conversions print the argument in the style of
+-`%e' or `%E' (respectively) if the exponent would be less than -4 or
+-greater than or equal to the precision; otherwise they use the `%f'
+-style. A precision of `0', is taken as 1. is Trailing zeros are
+-removed from the fractional portion of the result and a decimal-point
+-character appears only if it is followed by a digit.
+-
+- The `%a' and `%A' conversions are meant for representing
+-floating-point numbers exactly in textual form so that they can be
+-exchanged as texts between different programs and/or machines. The
+-numbers are represented is the form [`-']`0x'H`.'HHH`p'[`+'|`-']DD. At
+-the left of the decimal-point character exactly one digit is print.
+-This character is only `0' if the number is denormalized. Otherwise
+-the value is unspecified; it is implementation dependent how many bits
+-are used. The number of hexadecimal digits on the right side of the
+-decimal-point character is equal to the precision. If the precision is
+-zero it is determined to be large enough to provide an exact
+-representation of the number (or it is large enough to distinguish two
+-adjacent values if the `FLT_RADIX' is not a power of 2, *note Floating
+-Point Parameters::). For the `%a' conversion lower-case characters are
+-used to represent the hexadecimal number and the prefix and exponent
+-sign are printed as `0x' and `p' respectively. Otherwise upper-case
+-characters are used and `0X' and `P' are used for the representation of
+-prefix and exponent string. The exponent to the base of two is printed
+-as a decimal number using at least one digit but at most as many digits
+-as necessary to represent the value exactly.
+-
+- If the value to be printed represents infinity or a NaN, the output
+-is [`-']`inf' or `nan' respectively if the conversion specifier is
+-`%a', `%e', `%f', or `%g' and it is [`-']`INF' or `NAN' respectively if
+-the conversion is `%A', `%E', or `%G'.
+-
+- The following flags can be used to modify the behavior:
+-
+-`-'
+- Left-justify the result in the field. Normally the result is
+- right-justified.
+-
+-`+'
+- Always include a plus or minus sign in the result.
+-
+-` '
+- If the result doesn't start with a plus or minus sign, prefix it
+- with a space instead. Since the `+' flag ensures that the result
+- includes a sign, this flag is ignored if you supply both of them.
+-
+-`#'
+- Specifies that the result should always include a decimal point,
+- even if no digits follow it. For the `%g' and `%G' conversions,
+- this also forces trailing zeros after the decimal point to be left
+- in place where they would otherwise be removed.
+-
+-`''
+- Separate the digits of the integer part of the result into groups
+- as specified by the locale specified for the `LC_NUMERIC' category;
+- *note General Numeric::. This flag is a GNU extension.
+-
+-`0'
+- Pad the field with zeros instead of spaces; the zeros are placed
+- after any sign. This flag is ignored if the `-' flag is also
+- specified.
+-
+- The precision specifies how many digits follow the decimal-point
+-character for the `%f', `%e', and `%E' conversions. For these
+-conversions, the default precision is `6'. If the precision is
+-explicitly `0', this suppresses the decimal point character entirely.
+-For the `%g' and `%G' conversions, the precision specifies how many
+-significant digits to print. Significant digits are the first digit
+-before the decimal point, and all the digits after it. If the
+-precision is `0' or not specified for `%g' or `%G', it is treated like
+-a value of `1'. If the value being printed cannot be expressed
+-accurately in the specified number of digits, the value is rounded to
+-the nearest number that fits.
+-
+- Without a type modifier, the floating-point conversions use an
+-argument of type `double'. (By the default argument promotions, any
+-`float' arguments are automatically converted to `double'.) The
+-following type modifier is supported:
+-
+-`L'
+- An uppercase `L' specifies that the argument is a `long double'.
+-
+- Here are some examples showing how numbers print using the various
+-floating-point conversions. All of the numbers were printed using this
+-template string:
+-
+- "|%13.4a|%13.4f|%13.4e|%13.4g|\n"
+-
+- Here is the output:
+-
+- | 0x0.0000p+0| 0.0000| 0.0000e+00| 0|
+- | 0x1.0000p-1| 0.5000| 5.0000e-01| 0.5|
+- | 0x1.0000p+0| 1.0000| 1.0000e+00| 1|
+- | -0x1.0000p+0| -1.0000| -1.0000e+00| -1|
+- | 0x1.9000p+6| 100.0000| 1.0000e+02| 100|
+- | 0x1.f400p+9| 1000.0000| 1.0000e+03| 1000|
+- | 0x1.3880p+13| 10000.0000| 1.0000e+04| 1e+04|
+- | 0x1.81c8p+13| 12345.0000| 1.2345e+04| 1.234e+04|
+- | 0x1.86a0p+16| 100000.0000| 1.0000e+05| 1e+05|
+- | 0x1.e240p+16| 123456.0000| 1.2346e+05| 1.235e+05|

+-
+-Other Output Conversions
+-------------------------
+-
+- This section describes miscellaneous conversions for `printf'.
+-
+- The `%c' conversion prints a single character. In case there is no
+-`l' modifier the `int' argument is first converted to an `unsigned
+-char'. Then, if used in a wide stream function, the character is
+-converted into the corresponding wide character. The `-' flag can be
+-used to specify left-justification in the field, but no other flags are
+-defined, and no precision or type modifier can be given. For example:
+-
+- printf ("%c%c%c%c%c", 'h', 'e', 'l', 'l', 'o');
+-
+-prints `hello'.
+-
+- If there is a `l' modifier present the argument is expected to be of
+-type `wint_t'. If used in a multibyte function the wide character is
+-converted into a multibyte character before being added to the output.
+-In this case more than one output byte can be produced.
+-
+- The `%s' conversion prints a string. If no `l' modifier is present
+-the corresponding argument must be of type `char *' (or `const char
+-*'). If used in a wide stream function the string is first converted
+-in a wide character string. A precision can be specified to indicate
+-the maximum number of characters to write; otherwise characters in the
+-string up to but not including the terminating null character are
+-written to the output stream. The `-' flag can be used to specify
+-left-justification in the field, but no other flags or type modifiers
+-are defined for this conversion. For example:
+-
+- printf ("%3s%-6s", "no", "where");
+-
+-prints ` nowhere '.
+-
+- If there is a `l' modifier present the argument is expected to be of
+-type `wchar_t' (or `const wchar_t *').
+-
+- If you accidentally pass a null pointer as the argument for a `%s'
+-conversion, the GNU library prints it as `(null)'. We think this is
+-more useful than crashing. But it's not good practice to pass a null
+-argument intentionally.
+-
+- The `%m' conversion prints the string corresponding to the error
+-code in `errno'. *Note Error Messages::. Thus:
+-
+- fprintf (stderr, "can't open `%s': %m\n", filename);
+-
+-is equivalent to:
+-
+- fprintf (stderr, "can't open `%s': %s\n", filename, strerror (errno));
+-
+-The `%m' conversion is a GNU C library extension.
+-
+- The `%p' conversion prints a pointer value. The corresponding
+-argument must be of type `void *'. In practice, you can use any type
+-of pointer.
+-
+- In the GNU system, non-null pointers are printed as unsigned
+-integers, as if a `%#x' conversion were used. Null pointers print as
+-`(nil)'. (Pointers might print differently in other systems.)
+-
+- For example:
+-
+- printf ("%p", "testing");
+-
+-prints `0x' followed by a hexadecimal number--the address of the string
+-constant `"testing"'. It does not print the word `testing'.
+-
+- You can supply the `-' flag with the `%p' conversion to specify
+-left-justification, but no other flags, precision, or type modifiers
+-are defined.
+-
+- The `%n' conversion is unlike any of the other output conversions.
+-It uses an argument which must be a pointer to an `int', but instead of
+-printing anything it stores the number of characters printed so far by
+-this call at that location. The `h' and `l' type modifiers are
+-permitted to specify that the argument is of type `short int *' or
+-`long int *' instead of `int *', but no flags, field width, or
+-precision are permitted.
+-
+- For example,
+-
+- int nchar;
+- printf ("%d %s%n\n", 3, "bears", &nchar);
+-
+-prints:
+-
+- 3 bears
+-
+-and sets `nchar' to `7', because `3 bears' is seven characters.
+-
+- The `%%' conversion prints a literal `%' character. This conversion
+-doesn't use an argument, and no flags, field width, precision, or type
+-modifiers are permitted.

+-Prototypes for these functions are in the header file `stdio.h'.
+-Because these functions take a variable number of arguments, you _must_
+-declare prototypes for them before using them. Of course, the easiest
+-way to make sure you have all the right prototypes is to just include
+-`stdio.h'.
+-
+- - Function: int printf (const char *TEMPLATE, ...)
+- The `printf' function prints the optional arguments under the
+- control of the template string TEMPLATE to the stream `stdout'.
+- It returns the number of characters printed, or a negative value
+- if there was an output error.
+-
+- - Function: int wprintf (const wchar_t *TEMPLATE, ...)
+- The `wprintf' function prints the optional arguments under the
+- control of the wide template string TEMPLATE to the stream
+- `stdout'. It returns the number of wide characters printed, or a
+- negative value if there was an output error.
+-
+- - Function: int fprintf (FILE *STREAM, const char *TEMPLATE, ...)
+- This function is just like `printf', except that the output is
+- written to the stream STREAM instead of `stdout'.
+-
+- - Function: int fwprintf (FILE *STREAM, const wchar_t *TEMPLATE, ...)
+- This function is just like `wprintf', except that the output is
+- written to the stream STREAM instead of `stdout'.
+-
+- - Function: int sprintf (char *S, const char *TEMPLATE, ...)
+- This is like `printf', except that the output is stored in the
+- character array S instead of written to a stream. A null
+- character is written to mark the end of the string.
+-
+- The `sprintf' function returns the number of characters stored in
+- the array S, not including the terminating null character.
+-
+- The behavior of this function is undefined if copying takes place
+- between objects that overlap--for example, if S is also given as
+- an argument to be printed under control of the `%s' conversion.
+- *Note Copying and Concatenation::.
+-
+- *Warning:* The `sprintf' function can be *dangerous* because it
+- can potentially output more characters than can fit in the
+- allocation size of the string S. Remember that the field width
+- given in a conversion specification is only a _minimum_ value.
+-
+- To avoid this problem, you can use `snprintf' or `asprintf',
+- described below.
+-
+- - Function: int swprintf (wchar_t *S, size_t SIZE, const wchar_t
+- *TEMPLATE, ...)
+- This is like `wprintf', except that the output is stored in the
+- wide character array WS instead of written to a stream. A null
+- wide character is written to mark the end of the string. The SIZE
+- argument specifies the maximum number of characters to produce.
+- The trailing null character is counted towards this limit, so you
+- should allocate at least SIZE wide characters for the string WS.
+-
+- The return value is the number of characters generated for the
+- given input, excluding the trailing null. If not all output fits
+- into the provided buffer a negative value is returned. You should
+- try again with a bigger output string. _Note:_ this is different
+- from how `snprintf' handles this situation.
+-
+- Note that the corresponding narrow stream function takes fewer
+- parameters. `swprintf' in fact corresponds to the `snprintf'
+- function. Since the `sprintf' function can be dangerous and should
+- be avoided the ISO C committee refused to make the same mistake
+- again and decided to not define an function exactly corresponding
+- to `sprintf'.
+-
+- - Function: int snprintf (char *S, size_t SIZE, const char *TEMPLATE,
+- ...)
+- The `snprintf' function is similar to `sprintf', except that the
+- SIZE argument specifies the maximum number of characters to
+- produce. The trailing null character is counted towards this
+- limit, so you should allocate at least SIZE characters for the
+- string S.
+-
+- The return value is the number of characters which would be
+- generated for the given input, excluding the trailing null. If
+- this value is greater or equal to SIZE, not all characters from
+- the result have been stored in S. You should try again with a
+- bigger output string. Here is an example of doing this:
+-
+- /* Construct a message describing the value of a variable
+- whose name is NAME and whose value is VALUE. */
+- char *
+- make_message (char *name, char *value)
+- {
+- /* Guess we need no more than 100 chars of space. */
+- int size = 100;
+- char *buffer = (char *) xmalloc (size);
+- int nchars;
+- if (buffer == NULL)
+- return NULL;
+-
+- /* Try to print in the allocated space. */
+- nchars = snprintf (buffer, size, "value of %s is %s",
+- name, value);
+- if (nchars >= size)
+- {
+- /* Reallocate buffer now that we know
+- how much space is needed. */
+- buffer = (char *) xrealloc (buffer, nchars + 1);
+-
+- if (buffer != NULL)
+- /* Try again. */
+- snprintf (buffer, size, "value of %s is %s",
+- name, value);
+- }
+- /* The last call worked, return the string. */
+- return buffer;
+- }
+-
+- In practice, it is often easier just to use `asprintf', below.
+-
+- *Attention:* In versions of the GNU C library prior to 2.1 the
+- return value is the number of characters stored, not including the
+- terminating null; unless there was not enough space in S to store
+- the result in which case `-1' is returned. This was changed in
+- order to comply with the ISO C99 standard.

+-Dynamically Allocating Formatted Output
+----------------------------------------
+-
+- The functions in this section do formatted output and place the
+-results in dynamically allocated memory.
+-
+- - Function: int asprintf (char **PTR, const char *TEMPLATE, ...)
+- This function is similar to `sprintf', except that it dynamically
+- allocates a string (as with `malloc'; *note Unconstrained
+- Allocation::) to hold the output, instead of putting the output in
+- a buffer you allocate in advance. The PTR argument should be the
+- address of a `char *' object, and `asprintf' stores a pointer to
+- the newly allocated string at that location.
+-
+- The return value is the number of characters allocated for the
+- buffer, or less than zero if an error occurred. Usually this means
+- that the buffer could not be allocated.
+-
+- Here is how to use `asprintf' to get the same result as the
+- `snprintf' example, but more easily:
+-
+- /* Construct a message describing the value of a variable
+- whose name is NAME and whose value is VALUE. */
+- char *
+- make_message (char *name, char *value)
+- {
+- char *result;
+- if (asprintf (&result, "value of %s is %s", name, value) < 0)
+- return NULL;
+- return result;
+- }
+-
+- - Function: int obstack_printf (struct obstack *OBSTACK, const char
+- *TEMPLATE, ...)
+- This function is similar to `asprintf', except that it uses the
+- obstack OBSTACK to allocate the space. *Note Obstacks::.
+-
+- The characters are written onto the end of the current object. To
+- get at them, you must finish the object with `obstack_finish'
+- (*note Growing Objects::).

+-
+-Variable Arguments Output Functions
+------------------------------------
+-
+- The functions `vprintf' and friends are provided so that you can
+-define your own variadic `printf'-like functions that make use of the
+-same internals as the built-in formatted output functions.
+-
+- The most natural way to define such functions would be to use a
+-language construct to say, "Call `printf' and pass this template plus
+-all of my arguments after the first five." But there is no way to do
+-this in C, and it would be hard to provide a way, since at the C
+-language level there is no way to tell how many arguments your function
+-received.
+-
+- Since that method is impossible, we provide alternative functions,
+-the `vprintf' series, which lets you pass a `va_list' to describe "all
+-of my arguments after the first five."
+-
+- When it is sufficient to define a macro rather than a real function,
+-the GNU C compiler provides a way to do this much more easily with
+-macros. For example:
+-
+- #define myprintf(a, b, c, d, e, rest...) \
+- printf (mytemplate , ## rest)
+-
+-*Note Macros with Variable Numbers of Arguments: (gcc.info)Macro
+-Varargs, for details. But this is limited to macros, and does not
+-apply to real functions at all.
+-
+- Before calling `vprintf' or the other functions listed in this
+-section, you _must_ call `va_start' (*note Variadic Functions::) to
+-initialize a pointer to the variable arguments. Then you can call
+-`va_arg' to fetch the arguments that you want to handle yourself. This
+-advances the pointer past those arguments.
+-
+- Once your `va_list' pointer is pointing at the argument of your
+-choice, you are ready to call `vprintf'. That argument and all
+-subsequent arguments that were passed to your function are used by
+-`vprintf' along with the template that you specified separately.
+-
+- In some other systems, the `va_list' pointer may become invalid
+-after the call to `vprintf', so you must not use `va_arg' after you
+-call `vprintf'. Instead, you should call `va_end' to retire the
+-pointer from service. However, you can safely call `va_start' on
+-another pointer variable and begin fetching the arguments again through
+-that pointer. Calling `vprintf' does not destroy the argument list of
+-your function, merely the particular pointer that you passed to it.
+-
+- GNU C does not have such restrictions. You can safely continue to
+-fetch arguments from a `va_list' pointer after passing it to `vprintf',
+-and `va_end' is a no-op. (Note, however, that subsequent `va_arg'
+-calls will fetch the same arguments which `vprintf' previously used.)
+-
+- Prototypes for these functions are declared in `stdio.h'.
+-
+- - Function: int vprintf (const char *TEMPLATE, va_list AP)
+- This function is similar to `printf' except that, instead of taking
+- a variable number of arguments directly, it takes an argument list
+- pointer AP.
+-
+- - Function: int vwprintf (const wchar_t *TEMPLATE, va_list AP)
+- This function is similar to `wprintf' except that, instead of
+- taking a variable number of arguments directly, it takes an
+- argument list pointer AP.
+-
+- - Function: int vfprintf (FILE *STREAM, const char *TEMPLATE, va_list
+- AP)
+- This is the equivalent of `fprintf' with the variable argument list
+- specified directly as for `vprintf'.
+-
+- - Function: int vfwprintf (FILE *STREAM, const wchar_t *TEMPLATE,
+- va_list AP)
+- This is the equivalent of `fwprintf' with the variable argument
+- list specified directly as for `vwprintf'.
+-
+- - Function: int vsprintf (char *S, const char *TEMPLATE, va_list AP)
+- This is the equivalent of `sprintf' with the variable argument list
+- specified directly as for `vprintf'.
+-
+- - Function: int vswprintf (wchar_t *S, size_t SIZE, const wchar_t
+- *TEMPLATE, va_list AP)
+- This is the equivalent of `swprintf' with the variable argument
+- list specified directly as for `vwprintf'.
+-
+- - Function: int vsnprintf (char *S, size_t SIZE, const char *TEMPLATE,
+- va_list AP)
+- This is the equivalent of `snprintf' with the variable argument
+- list specified directly as for `vprintf'.
+-
+- - Function: int vasprintf (char **PTR, const char *TEMPLATE, va_list
+- AP)
+- The `vasprintf' function is the equivalent of `asprintf' with the
+- variable argument list specified directly as for `vprintf'.
+-
+- - Function: int obstack_vprintf (struct obstack *OBSTACK, const char
+- *TEMPLATE, va_list AP)
+- The `obstack_vprintf' function is the equivalent of
+- `obstack_printf' with the variable argument list specified directly
+- as for `vprintf'.
+-
+- Here's an example showing how you might use `vfprintf'. This is a
+-function that prints error messages to the stream `stderr', along with
+-a prefix indicating the name of the program (*note Error Messages::,
+-for a description of `program_invocation_short_name').
+-
+- #include <stdio.h>
+- #include <stdarg.h>
+-
+- void
+- eprintf (const char *template, ...)
+- {
+- va_list ap;
+- extern char *program_invocation_short_name;
+-
+- fprintf (stderr, "%s: ", program_invocation_short_name);
+- va_start (ap, template);
+- vfprintf (stderr, template, ap);
+- va_end (ap);
+- }
+-
+-You could call `eprintf' like this:
+-
+- eprintf ("file `%s' does not exist\n", filename);
+-
+- In GNU C, there is a special construct you can use to let the
+-compiler know that a function uses a `printf'-style format string.
+-Then it can check the number and types of arguments in each call to the
+-function, and warn you when they do not match the format string. For
+-example, take this declaration of `eprintf':
+-
+- void eprintf (const char *template, ...)
+- __attribute__ ((format (printf, 1, 2)));
+-
+-This tells the compiler that `eprintf' uses a format string like
+-`printf' (as opposed to `scanf'; *note Formatted Input::); the format
+-string appears as the first argument; and the arguments to satisfy the
+-format begin with the second. *Note Declaring Attributes of Functions:

+-
+-Parsing a Template String
+--------------------------
+-
+- You can use the function `parse_printf_format' to obtain information
+-about the number and types of arguments that are expected by a given
+-template string. This function permits interpreters that provide
+-interfaces to `printf' to avoid passing along invalid arguments from
+-the user's program, which could cause a crash.
+-
+- All the symbols described in this section are declared in the header
+-file `printf.h'.
+-
+- - Function: size_t parse_printf_format (const char *TEMPLATE, size_t
+- N, int *ARGTYPES)
+- This function returns information about the number and types of
+- arguments expected by the `printf' template string TEMPLATE. The
+- information is stored in the array ARGTYPES; each element of this
+- array describes one argument. This information is encoded using
+- the various `PA_' macros, listed below.
+-
+- The argument N specifies the number of elements in the array
+- ARGTYPES. This is the maximum number of elements that
+- `parse_printf_format' will try to write.
+-
+- `parse_printf_format' returns the total number of arguments
+- required by TEMPLATE. If this number is greater than N, then the
+- information returned describes only the first N arguments. If you
+- want information about additional arguments, allocate a bigger
+- array and call `parse_printf_format' again.
+-
+- The argument types are encoded as a combination of a basic type and
+-modifier flag bits.
+-
+- - Macro: int PA_FLAG_MASK
+- This macro is a bitmask for the type modifier flag bits. You can
+- write the expression `(argtypes[i] & PA_FLAG_MASK)' to extract
+- just the flag bits for an argument, or `(argtypes[i] &
+- ~PA_FLAG_MASK)' to extract just the basic type code.
+-
+- Here are symbolic constants that represent the basic types; they
+-stand for integer values.
+-
+-`PA_INT'
+- This specifies that the base type is `int'.
+-
+-`PA_CHAR'
+- This specifies that the base type is `int', cast to `char'.
+-
+-`PA_STRING'
+- This specifies that the base type is `char *', a null-terminated
+- string.
+-
+-`PA_POINTER'
+- This specifies that the base type is `void *', an arbitrary
+- pointer.
+-
+-`PA_FLOAT'
+- This specifies that the base type is `float'.
+-
+-`PA_DOUBLE'
+- This specifies that the base type is `double'.
+-
+-`PA_LAST'
+- You can define additional base types for your own programs as
+- offsets from `PA_LAST'. For example, if you have data types `foo'
+- and `bar' with their own specialized `printf' conversions, you
+- could define encodings for these types as:
+-
+- #define PA_FOO PA_LAST
+- #define PA_BAR (PA_LAST + 1)
+-
+- Here are the flag bits that modify a basic type. They are combined
+-with the code for the basic type using inclusive-or.
+-
+-`PA_FLAG_PTR'
+- If this bit is set, it indicates that the encoded type is a
+- pointer to the base type, rather than an immediate value. For
+- example, `PA_INT|PA_FLAG_PTR' represents the type `int *'.
+-
+-`PA_FLAG_SHORT'
+- If this bit is set, it indicates that the base type is modified
+- with `short'. (This corresponds to the `h' type modifier.)
+-
+-`PA_FLAG_LONG'
+- If this bit is set, it indicates that the base type is modified
+- with `long'. (This corresponds to the `l' type modifier.)
+-
+-`PA_FLAG_LONG_LONG'
+- If this bit is set, it indicates that the base type is modified
+- with `long long'. (This corresponds to the `L' type modifier.)
+-
+-`PA_FLAG_LONG_DOUBLE'
+- This is a synonym for `PA_FLAG_LONG_LONG', used by convention with
+- a base type of `PA_DOUBLE' to indicate a type of `long double'.

+-Customizing `printf'
+-====================
+-
+- The GNU C library lets you define your own custom conversion
+-specifiers for `printf' template strings, to teach `printf' clever ways
+-to print the important data structures of your program.
+-
+- The way you do this is by registering the conversion with the
+-function `register_printf_function'; see *Note Registering New
+-Conversions::. One of the arguments you pass to this function is a
+-pointer to a handler function that produces the actual output; see
+-*Note Defining the Output Handler::, for information on how to write
+-this function.
+-
+- You can also install a function that just returns information about
+-the number and type of arguments expected by the conversion specifier.
+-*Note Parsing a Template String::, for information about this.
+-
+- The facilities of this section are declared in the header file
+-`printf.h'.

+-
+-Registering New Conversions
+----------------------------
+-
+- The function to register a new output conversion is
+-`register_printf_function', declared in `printf.h'.
+-
+- - Function: int register_printf_function (int SPEC, printf_function
+- HANDLER-FUNCTION, printf_arginfo_function ARGINFO-FUNCTION)
+- This function defines the conversion specifier character SPEC.
+- Thus, if SPEC is `'Y'', it defines the conversion `%Y'. You can
+- redefine the built-in conversions like `%s', but flag characters
+- like `#' and type modifiers like `l' can never be used as
+- conversions; calling `register_printf_function' for those
+- characters has no effect. It is advisable not to use lowercase
+- letters, since the ISO C standard warns that additional lowercase
+- letters may be standardized in future editions of the standard.
+-
+- The HANDLER-FUNCTION is the function called by `printf' and
+- friends when this conversion appears in a template string. *Note
+- Defining the Output Handler::, for information about how to define
+- a function to pass as this argument. If you specify a null
+- pointer, any existing handler function for SPEC is removed.
+-
+- The ARGINFO-FUNCTION is the function called by
+- `parse_printf_format' when this conversion appears in a template
+- string. *Note Parsing a Template String::, for information about
+- this.
+-
+- *Attention:* In the GNU C library versions before 2.0 the
+- ARGINFO-FUNCTION function did not need to be installed unless the
+- user used the `parse_printf_format' function. This has changed.
+- Now a call to any of the `printf' functions will call this
+- function when this format specifier appears in the format string.
+-
+- The return value is `0' on success, and `-1' on failure (which
+- occurs if SPEC is out of range).
+-
+- You can redefine the standard output conversions, but this is
+- probably not a good idea because of the potential for confusion.
+- Library routines written by other people could break if you do
+- this.

+-Conversion Specifier Options
+-----------------------------
+-
+- If you define a meaning for `%A', what if the template contains
+-`%+23A' or `%-#A'? To implement a sensible meaning for these, the
+-handler when called needs to be able to get the options specified in
+-the template.
+-
+- Both the HANDLER-FUNCTION and ARGINFO-FUNCTION accept an argument
+-that points to a `struct printf_info', which contains information about
+-the options appearing in an instance of the conversion specifier. This
+-data type is declared in the header file `printf.h'.
+-
+- - Type: struct printf_info
+- This structure is used to pass information about the options
+- appearing in an instance of a conversion specifier in a `printf'
+- template string to the handler and arginfo functions for that
+- specifier. It contains the following members:
+-
+- `int prec'
+- This is the precision specified. The value is `-1' if no
+- precision was specified. If the precision was given as `*',
+- the `printf_info' structure passed to the handler function
+- contains the actual value retrieved from the argument list.
+- But the structure passed to the arginfo function contains a
+- value of `INT_MIN', since the actual value is not known.
+-
+- `int width'
+- This is the minimum field width specified. The value is `0'
+- if no width was specified. If the field width was given as
+- `*', the `printf_info' structure passed to the handler
+- function contains the actual value retrieved from the
+- argument list. But the structure passed to the arginfo
+- function contains a value of `INT_MIN', since the actual
+- value is not known.
+-
+- `wchar_t spec'
+- This is the conversion specifier character specified. It's
+- stored in the structure so that you can register the same
+- handler function for multiple characters, but still have a
+- way to tell them apart when the handler function is called.
+-
+- `unsigned int is_long_double'
+- This is a boolean that is true if the `L', `ll', or `q' type
+- modifier was specified. For integer conversions, this
+- indicates `long long int', as opposed to `long double' for
+- floating point conversions.
+-
+- `unsigned int is_char'
+- This is a boolean that is true if the `hh' type modifier was
+- specified.
+-
+- `unsigned int is_short'
+- This is a boolean that is true if the `h' type modifier was
+- specified.
+-
+- `unsigned int is_long'
+- This is a boolean that is true if the `l' type modifier was
+- specified.
+-
+- `unsigned int alt'
+- This is a boolean that is true if the `#' flag was specified.
+-
+- `unsigned int space'
+- This is a boolean that is true if the ` ' flag was specified.
+-
+- `unsigned int left'
+- This is a boolean that is true if the `-' flag was specified.
+-
+- `unsigned int showsign'
+- This is a boolean that is true if the `+' flag was specified.
+-
+- `unsigned int group'
+- This is a boolean that is true if the `'' flag was specified.
+-
+- `unsigned int extra'
+- This flag has a special meaning depending on the context. It
+- could be used freely by the user-defined handlers but when
+- called from the `printf' function this variable always
+- contains the value `0'.
+-
+- `unsigned int wide'
+- This flag is set if the stream is wide oriented.
+-
+- `wchar_t pad'
+- This is the character to use for padding the output to the
+- minimum field width. The value is `'0'' if the `0' flag was
+- specified, and `' '' otherwise.

+-
+-Defining the Output Handler
+----------------------------
+-
+- Now let's look at how to define the handler and arginfo functions
+-which are passed as arguments to `register_printf_function'.
+-
+- *Compatibility Note:* The interface changed in GNU libc version 2.0.
+-Previously the third argument was of type `va_list *'.
+-
+- You should define your handler functions with a prototype like:
+-
+- int FUNCTION (FILE *stream, const struct printf_info *info,
+- const void *const *args)
+-
+- The STREAM argument passed to the handler function is the stream to
+-which it should write output.
+-
+- The INFO argument is a pointer to a structure that contains
+-information about the various options that were included with the
+-conversion in the template string. You should not modify this structure
+-inside your handler function. *Note Conversion Specifier Options::, for
+-a description of this data structure.
+-
+- The ARGS is a vector of pointers to the arguments data. The number
+-of arguments was determined by calling the argument information
+-function provided by the user.
+-
+- Your handler function should return a value just like `printf' does:
+-it should return the number of characters it has written, or a negative
+-value to indicate an error.
+-
+- - Data Type: printf_function
+- This is the data type that a handler function should have.
+-
+- If you are going to use `parse_printf_format' in your application,
+-you must also define a function to pass as the ARGINFO-FUNCTION
+-argument for each new conversion you install with
+-`register_printf_function'.
+-
+- You have to define these functions with a prototype like:
+-
+- int FUNCTION (const struct printf_info *info,
+- size_t n, int *argtypes)
+-
+- The return value from the function should be the number of arguments
+-the conversion expects. The function should also fill in no more than

+-`printf' Extension Example
+---------------------------
+-
+- Here is an example showing how to define a `printf' handler function.
+-This program defines a data structure called a `Widget' and defines the
+-`%W' conversion to print information about `Widget *' arguments,
+-including the pointer value and the name stored in the data structure.
+-The `%W' conversion supports the minimum field width and
+-left-justification options, but ignores everything else.
+-
+- #include <stdio.h>
+- #include <stdlib.h>
+- #include <printf.h>
+-
+- typedef struct
+- {
+- char *name;
+- }
+- Widget;
+-
+- int
+- print_widget (FILE *stream,
+- const struct printf_info *info,
+- const void *const *args)
+- {
+- const Widget *w;
+- char *buffer;
+- int len;
+-
+- /* Format the output into a string. */
+- w = *((const Widget **) (args[0]));
+- len = asprintf (&buffer, "<Widget %p: %s>", w, w->name);
+- if (len == -1)
+- return -1;
+-
+- /* Pad to the minimum field width and print to the stream. */
+- len = fprintf (stream, "%*s",
+- (info->left ? -info->width : info->width),
+- buffer);
+-
+- /* Clean up and return. */
+- free (buffer);
+- return len;
+- }
+-
+-
+- int
+- print_widget_arginfo (const struct printf_info *info, size_t n,
+- int *argtypes)
+- {
+- /* We always take exactly one argument and this is a pointer to the
+- structure.. */
+- if (n > 0)
+- argtypes[0] = PA_POINTER;
+- return 1;
+- }
+-
+-
+- int
+- main (void)
+- {
+- /* Make a widget to print. */
+- Widget mywidget;
+- mywidget.name = "mywidget";
+-
+- /* Register the print function for widgets. */
+- register_printf_function ('W', print_widget, print_widget_arginfo);
+-
+- /* Now print the widget. */
+- printf ("|%W|\n", &mywidget);
+- printf ("|%35W|\n", &mywidget);
+- printf ("|%-35W|\n", &mywidget);
+-
+- return 0;
+- }
+-
+- The output produced by this program looks like:
+-
+- |<Widget 0xffeffb7c: mywidget>|
+- | <Widget 0xffeffb7c: mywidget>|
+- |<Widget 0xffeffb7c: mywidget> |

+-
+-Predefined `printf' Handlers
+-----------------------------
+-
+- The GNU libc also contains a concrete and useful application of the
+-`printf' handler extension. There are two functions available which
+-implement a special way to print floating-point numbers.
+-
+- - Function: int printf_size (FILE *FP, const struct printf_info *INFO,
+- const void *const *ARGS)
+- Print a given floating point number as for the format `%f' except
+- that there is a postfix character indicating the divisor for the
+- number to make this less than 1000. There are two possible
+- divisors: powers of 1024 or powers of 1000. Which one is used
+- depends on the format character specified while registered this
+- handler. If the character is of lower case, 1024 is used. For
+- upper case characters, 1000 is used.
+-
+- The postfix tag corresponds to bytes, kilobytes, megabytes,
+- gigabytes, etc. The full table is:
+-
+- +------+--------------+--------+--------+---------------+
+- |low|Multiplier|From|Upper|Multiplier|
+- +------+--------------+--------+--------+---------------+
+- |' '|1||' '|1|
+- +------+--------------+--------+--------+---------------+
+- |k|2^10 (1024)|kilo|K|10^3 (1000)|
+- +------+--------------+--------+--------+---------------+
+- |m|2^20|mega|M|10^6|
+- +------+--------------+--------+--------+---------------+
+- |g|2^30|giga|G|10^9|
+- +------+--------------+--------+--------+---------------+
+- |t|2^40|tera|T|10^12|
+- +------+--------------+--------+--------+---------------+
+- |p|2^50|peta|P|10^15|
+- +------+--------------+--------+--------+---------------+
+- |e|2^60|exa|E|10^18|
+- +------+--------------+--------+--------+---------------+
+- |z|2^70|zetta|Z|10^21|
+- +------+--------------+--------+--------+---------------+
+- |y|2^80|yotta|Y|10^24|
+- +------+--------------+--------+--------+---------------+
+-
+- The default precision is 3, i.e., 1024 is printed with a lower-case
+- format character as if it were `%.3fk' and will yield `1.000k'.
+-
+- Due to the requirements of `register_printf_function' we must also
+-provide the function which returns information about the arguments.
+-
+- - Function: int printf_size_info (const struct printf_info *INFO,
+- size_t N, int *ARGTYPES)
+- This function will return in ARGTYPES the information about the
+- used parameters in the way the `vfprintf' implementation expects
+- it. The format always takes one argument.
+-
+- To use these functions both functions must be registered with a call
+-like
+-
+- register_printf_function ('B', printf_size, printf_size_info);
+-
+- Here we register the functions to print numbers as powers of 1000
+-since the format character `'B'' is an upper-case character. If we
+-would additionally use `'b'' in a line like
+-
+- register_printf_function ('b', printf_size, printf_size_info);
+-
+-we could also print using a power of 1024. Please note that all that is
+-different in these two lines is the format specifier. The
+-`printf_size' function knows about the difference between lower and
+-upper case format specifiers.
+-
+- The use of `'B'' and `'b'' is no coincidence. Rather it is the
+-preferred way to use this functionality since it is available on some
+-other systems which also use format specifiers.

+-Formatted Input
+-===============
+-
+- The functions described in this section (`scanf' and related
+-functions) provide facilities for formatted input analogous to the
+-formatted output facilities. These functions provide a mechanism for
+-reading arbitrary values under the control of a "format string" or
+-"template string".

+-
+-Formatted Input Basics
+-----------------------
+-
+- Calls to `scanf' are superficially similar to calls to `printf' in
+-that arbitrary arguments are read under the control of a template
+-string. While the syntax of the conversion specifications in the
+-template is very similar to that for `printf', the interpretation of
+-the template is oriented more towards free-format input and simple
+-pattern matching, rather than fixed-field formatting. For example,
+-most `scanf' conversions skip over any amount of "white space"
+-(including spaces, tabs, and newlines) in the input file, and there is
+-no concept of precision for the numeric input conversions as there is
+-for the corresponding output conversions. Ordinarily, non-whitespace
+-characters in the template are expected to match characters in the
+-input stream exactly, but a matching failure is distinct from an input
+-error on the stream.
+-
+- Another area of difference between `scanf' and `printf' is that you
+-must remember to supply pointers rather than immediate values as the
+-optional arguments to `scanf'; the values that are read are stored in
+-the objects that the pointers point to. Even experienced programmers
+-tend to forget this occasionally, so if your program is getting strange
+-errors that seem to be related to `scanf', you might want to
+-double-check this.
+-
+- When a "matching failure" occurs, `scanf' returns immediately,
+-leaving the first non-matching character as the next character to be
+-read from the stream. The normal return value from `scanf' is the
+-number of values that were assigned, so you can use this to determine if
+-a matching error happened before all the expected values were read.
+-
+- The `scanf' function is typically used for things like reading in
+-the contents of tables. For example, here is a function that uses
+-`scanf' to initialize an array of `double':
+-
+- void
+- readarray (double *array, int n)
+- {
+- int i;
+- for (i=0; i<n; i++)
+- if (scanf (" %lf", &(array[i])) != 1)
+- invalid_input_error ();
+- }
+-
+- The formatted input functions are not used as frequently as the
+-formatted output functions. Partly, this is because it takes some care
+-to use them properly. Another reason is that it is difficult to recover
+-from a matching error.
+-
+- If you are trying to read input that doesn't match a single, fixed
+-pattern, you may be better off using a tool such as Flex to generate a
+-lexical scanner, or Bison to generate a parser, rather than using
+-`scanf'. For more information about these tools, see *Note Top:
+-(flex.info)Top, and *Note Top: (bison.info)Top.

+-
+-Input Conversion Syntax
+------------------------
+-
+- A `scanf' template string is a string that contains ordinary
+-multibyte characters interspersed with conversion specifications that
+-start with `%'.
+-
+- Any whitespace character (as defined by the `isspace' function;
+-*note Classification of Characters::) in the template causes any number
+-of whitespace characters in the input stream to be read and discarded.
+-The whitespace characters that are matched need not be exactly the same
+-whitespace characters that appear in the template string. For example,
+-write ` , ' in the template to recognize a comma with optional
+-whitespace before and after.
+-
+- Other characters in the template string that are not part of
+-conversion specifications must match characters in the input stream
+-exactly; if this is not the case, a matching failure occurs.
+-
+- The conversion specifications in a `scanf' template string have the
+-general form:
+-
+- % FLAGS WIDTH TYPE CONVERSION
+-
+- In more detail, an input conversion specification consists of an
+-initial `%' character followed in sequence by:
+-
+- * An optional "flag character" `*', which says to ignore the text
+- read for this specification. When `scanf' finds a conversion
+- specification that uses this flag, it reads input as directed by
+- the rest of the conversion specification, but it discards this
+- input, does not use a pointer argument, and does not increment the
+- count of successful assignments.
+-
+- * An optional flag character `a' (valid with string conversions only)
+- which requests allocation of a buffer long enough to store the
+- string in. (This is a GNU extension.) *Note Dynamic String
+- Input::.
+-
+- * An optional decimal integer that specifies the "maximum field
+- width". Reading of characters from the input stream stops either
+- when this maximum is reached or when a non-matching character is
+- found, whichever happens first. Most conversions discard initial
+- whitespace characters (those that don't are explicitly
+- documented), and these discarded characters don't count towards
+- the maximum field width. String input conversions store a null
+- character to mark the end of the input; the maximum field width
+- does not include this terminator.
+-
+- * An optional "type modifier character". For example, you can
+- specify a type modifier of `l' with integer conversions such as
+- `%d' to specify that the argument is a pointer to a `long int'
+- rather than a pointer to an `int'.
+-
+- * A character that specifies the conversion to be applied.
+-
+- The exact options that are permitted and how they are interpreted
+-vary between the different conversion specifiers. See the descriptions
+-of the individual conversions for information about the particular
+-options that they allow.
+-
+- With the `-Wformat' option, the GNU C compiler checks calls to
+-`scanf' and related functions. It examines the format string and
+-verifies that the correct number and types of arguments are supplied.
+-There is also a GNU C syntax to tell the compiler that a function you
+-write uses a `scanf'-style format string. *Note Declaring Attributes
+-of Functions: (gcc.info)Function Attributes, for more information.

+-Table of Input Conversions
+---------------------------
+-
+- Here is a table that summarizes the various conversion
+-specifications:
+-
+-`%d'
+- Matches an optionally signed integer written in decimal. *Note
+- Numeric Input Conversions::.
+-
+-`%i'
+- Matches an optionally signed integer in any of the formats that
+- the C language defines for specifying an integer constant. *Note
+- Numeric Input Conversions::.
+-
+-`%o'
+- Matches an unsigned integer written in octal radix. *Note Numeric
+- Input Conversions::.
+-
+-`%u'
+- Matches an unsigned integer written in decimal radix. *Note
+- Numeric Input Conversions::.
+-
+-`%x', `%X'
+- Matches an unsigned integer written in hexadecimal radix. *Note
+- Numeric Input Conversions::.
+-
+-`%e', `%f', `%g', `%E', `%G'
+- Matches an optionally signed floating-point number. *Note Numeric
+- Input Conversions::.
+-
+-`%s'
+- Matches a string containing only non-whitespace characters. *Note
+- String Input Conversions::. The presence of the `l' modifier
+- determines whether the output is stored as a wide character string
+- or a multibyte string. If `%s' is used in a wide character
+- function the string is converted as with multiple calls to
+- `wcrtomb' into a multibyte string. This means that the buffer
+- must provide room for `MB_CUR_MAX' bytes for each wide character
+- read. In case `%ls' is used in a multibyte function the result is
+- converted into wide characters as with multiple calls of `mbrtowc'
+- before being stored in the user provided buffer.
+-
+-`%S'
+- This is an alias for `%ls' which is supported for compatibility
+- with the Unix standard.
+-
+-`%['
+- Matches a string of characters that belong to a specified set.
+- *Note String Input Conversions::. The presence of the `l' modifier
+- determines whether the output is stored as a wide character string
+- or a multibyte string. If `%[' is used in a wide character
+- function the string is converted as with multiple calls to
+- `wcrtomb' into a multibyte string. This means that the buffer
+- must provide room for `MB_CUR_MAX' bytes for each wide character
+- read. In case `%l[' is used in a multibyte function the result is
+- converted into wide characters as with multiple calls of `mbrtowc'
+- before being stored in the user provided buffer.
+-
+-`%c'
+- Matches a string of one or more characters; the number of
+- characters read is controlled by the maximum field width given for
+- the conversion. *Note String Input Conversions::.
+-
+- If the `%c' is used in a wide stream function the read value is
+- converted from a wide character to the corresponding multibyte
+- character before storing it. Note that this conversion can
+- produce more than one byte of output and therefore the provided
+- buffer be large enough for up to `MB_CUR_MAX' bytes for each
+- character. If `%lc' is used in a multibyte function the input is
+- treated as a multibyte sequence (and not bytes) and the result is
+- converted as with calls to `mbrtowc'.
+-
+-`%C'
+- This is an alias for `%lc' which is supported for compatibility
+- with the Unix standard.
+-
+-`%p'
+- Matches a pointer value in the same implementation-defined format
+- used by the `%p' output conversion for `printf'. *Note Other
+- Input Conversions::.
+-
+-`%n'
+- This conversion doesn't read any characters; it records the number
+- of characters read so far by this call. *Note Other Input
+- Conversions::.
+-
+-`%%'
+- This matches a literal `%' character in the input stream. No
+- corresponding argument is used. *Note Other Input Conversions::.
+-
+- If the syntax of a conversion specification is invalid, the behavior
+-is undefined. If there aren't enough function arguments provided to
+-supply addresses for all the conversion specifications in the template
+-strings that perform assignments, or if the arguments are not of the
+-correct types, the behavior is also undefined. On the other hand, extra
+-arguments are simply ignored.

+-Numeric Input Conversions
+--------------------------
+-
+- This section describes the `scanf' conversions for reading numeric
+-values.
+-
+- The `%d' conversion matches an optionally signed integer in decimal
+-radix. The syntax that is recognized is the same as that for the
+-`strtol' function (*note Parsing of Integers::) with the value `10' for
+-the BASE argument.
+-
+- The `%i' conversion matches an optionally signed integer in any of
+-the formats that the C language defines for specifying an integer
+-constant. The syntax that is recognized is the same as that for the
+-`strtol' function (*note Parsing of Integers::) with the value `0' for
+-the BASE argument. (You can print integers in this syntax with
+-`printf' by using the `#' flag character with the `%x', `%o', or `%d'
+-conversion. *Note Integer Conversions::.)
+-
+- For example, any of the strings `10', `0xa', or `012' could be read
+-in as integers under the `%i' conversion. Each of these specifies a
+-number with decimal value `10'.
+-
+- The `%o', `%u', and `%x' conversions match unsigned integers in
+-octal, decimal, and hexadecimal radices, respectively. The syntax that
+-is recognized is the same as that for the `strtoul' function (*note
+-Parsing of Integers::) with the appropriate value (`8', `10', or `16')
+-for the BASE argument.
+-
+- The `%X' conversion is identical to the `%x' conversion. They both
+-permit either uppercase or lowercase letters to be used as digits.
+-
+- The default type of the corresponding argument for the `%d' and `%i'
+-conversions is `int *', and `unsigned int *' for the other integer
+-conversions. You can use the following type modifiers to specify other
+-sizes of integer:
+-
+-`hh'
+- Specifies that the argument is a `signed char *' or `unsigned char
+- *'.
+-
+- This modifier was introduced in ISO C99.
+-
+-`h'
+- Specifies that the argument is a `short int *' or `unsigned short
+- int *'.
+-
+-`j'
+- Specifies that the argument is a `intmax_t *' or `uintmax_t *'.
+-
+- This modifier was introduced in ISO C99.
+-
+-`l'
+- Specifies that the argument is a `long int *' or `unsigned long
+- int *'. Two `l' characters is like the `L' modifier, below.
+-
+- If used with `%c' or `%s' the corresponding parameter is
+- considered as a pointer to a wide character or wide character
+- string respectively. This use of `l' was introduced in
+- Amendment 1 to ISO C90.
+-
+-`ll'
+-`L'
+-`q'
+- Specifies that the argument is a `long long int *' or `unsigned
+- long long int *'. (The `long long' type is an extension supported
+- by the GNU C compiler. For systems that don't provide extra-long
+- integers, this is the same as `long int'.)
+-
+- The `q' modifier is another name for the same thing, which comes
+- from 4.4 BSD; a `long long int' is sometimes called a "quad" `int'.
+-
+-`t'
+- Specifies that the argument is a `ptrdiff_t *'.
+-
+- This modifier was introduced in ISO C99.
+-
+-`z'
+- Specifies that the argument is a `size_t *'.
+-
+- This modifier was introduced in ISO C99.
+-
+- All of the `%e', `%f', `%g', `%E', and `%G' input conversions are
+-interchangeable. They all match an optionally signed floating point
+-number, in the same syntax as for the `strtod' function (*note Parsing
+-of Floats::).
+-
+- For the floating-point input conversions, the default argument type
+-is `float *'. (This is different from the corresponding output
+-conversions, where the default type is `double'; remember that `float'
+-arguments to `printf' are converted to `double' by the default argument
+-promotions, but `float *' arguments are not promoted to `double *'.)
+-You can specify other sizes of float using these type modifiers:
+-
+-`l'
+- Specifies that the argument is of type `double *'.
+-
+-`L'
+- Specifies that the argument is of type `long double *'.
+-
+- For all the above number parsing formats there is an additional
+-optional flag `''. When this flag is given the `scanf' function
+-expects the number represented in the input string to be formatted
+-according to the grouping rules of the currently selected locale (*note
+-General Numeric::).
+-
+- If the `"C"' or `"POSIX"' locale is selected there is no difference.
+-But for a locale which specifies values for the appropriate fields in
+-the locale the input must have the correct form in the input.
+-Otherwise the longest prefix with a correct form is processed.

+-
+-String Input Conversions
+-------------------------
+-
+- This section describes the `scanf' input conversions for reading
+-string and character values: `%s', `%S', `%[', `%c', and `%C'.
+-
+- You have two options for how to receive the input from these
+-conversions:
+-
+- * Provide a buffer to store it in. This is the default. You should
+- provide an argument of type `char *' or `wchar_t *' (the latter of
+- the `l' modifier is present).
+-
+- *Warning:* To make a robust program, you must make sure that the
+- input (plus its terminating null) cannot possibly exceed the size
+- of the buffer you provide. In general, the only way to do this is
+- to specify a maximum field width one less than the buffer size.
+- *If you provide the buffer, always specify a maximum field width
+- to prevent overflow.*
+-
+- * Ask `scanf' to allocate a big enough buffer, by specifying the `a'
+- flag character. This is a GNU extension. You should provide an
+- argument of type `char **' for the buffer address to be stored in.
+- *Note Dynamic String Input::.
+-
+- The `%c' conversion is the simplest: it matches a fixed number of
+-characters, always. The maximum field width says how many characters to
+-read; if you don't specify the maximum, the default is 1. This
+-conversion doesn't append a null character to the end of the text it
+-reads. It also does not skip over initial whitespace characters. It
+-reads precisely the next N characters, and fails if it cannot get that
+-many. Since there is always a maximum field width with `%c' (whether
+-specified, or 1 by default), you can always prevent overflow by making
+-the buffer long enough.
+-
+- If the format is `%lc' or `%C' the function stores wide characters
+-which are converted using the conversion determined at the time the
+-stream was opened from the external byte stream. The number of bytes
+-read from the medium is limited by `MB_CUR_LEN * N' but at most N wide
+-character get stored in the output string.
+-
+- The `%s' conversion matches a string of non-whitespace characters.
+-It skips and discards initial whitespace, but stops when it encounters
+-more whitespace after having read something. It stores a null character
+-at the end of the text that it reads.
+-
+- For example, reading the input:
+-
+- hello, world
+-
+-with the conversion `%10c' produces `" hello, wo"', but reading the
+-same input with the conversion `%10s' produces `"hello,"'.
+-
+- *Warning:* If you do not specify a field width for `%s', then the
+-number of characters read is limited only by where the next whitespace
+-character appears. This almost certainly means that invalid input can
+-make your program crash--which is a bug.
+-
+- The `%ls' and `%S' format are handled just like `%s' except that the
+-external byte sequence is converted using the conversion associated
+-with the stream to wide characters with their own encoding. A width or
+-precision specified with the format do not directly determine how many
+-bytes are read from the stream since they measure wide characters. But
+-an upper limit can be computed by multiplying the value of the width or
+-precision by `MB_CUR_MAX'.
+-
+- To read in characters that belong to an arbitrary set of your choice,
+-use the `%[' conversion. You specify the set between the `[' character
+-and a following `]' character, using the same syntax used in regular
+-expressions. As special cases:
+-
+- * A literal `]' character can be specified as the first character of
+- the set.
+-
+- * An embedded `-' character (that is, one that is not the first or
+- last character of the set) is used to specify a range of
+- characters.
+-
+- * If a caret character `^' immediately follows the initial `[', then
+- the set of allowed input characters is the everything _except_ the
+- characters listed.
+-
+- The `%[' conversion does not skip over initial whitespace characters.
+-
+- Here are some examples of `%[' conversions and what they mean:
+-
+-`%25[1234567890]'
+- Matches a string of up to 25 digits.
+-
+-`%25[][]'
+- Matches a string of up to 25 square brackets.
+-
+-`%25[^ \f\n\r\t\v]'
+- Matches a string up to 25 characters long that doesn't contain any
+- of the standard whitespace characters. This is slightly different
+- from `%s', because if the input begins with a whitespace character,
+- `%[' reports a matching failure while `%s' simply discards the
+- initial whitespace.
+-
+-`%25[a-z]'
+- Matches up to 25 lowercase characters.
+-
+- As for `%c' and `%s' the `%[' format is also modified to produce
+-wide characters if the `l' modifier is present. All what is said about
+-`%ls' above is true for `%l['.
+-
+- One more reminder: the `%s' and `%[' conversions are *dangerous* if
+-you don't specify a maximum width or use the `a' flag, because input
+-too long would overflow whatever buffer you have provided for it. No
+-matter how long your buffer is, a user could supply input that is
+-longer. A well-written program reports invalid input with a
+-comprehensible error message, not with a crash.

+-
+-Dynamically Allocating String Conversions
+------------------------------------------
+-
+- A GNU extension to formatted input lets you safely read a string
+-with no maximum size. Using this feature, you don't supply a buffer;
+-instead, `scanf' allocates a buffer big enough to hold the data and
+-gives you its address. To use this feature, write `a' as a flag
+-character, as in `%as' or `%a[0-9a-z]'.
+-
+- The pointer argument you supply for where to store the input should
+-have type `char **'. The `scanf' function allocates a buffer and
+-stores its address in the word that the argument points to. You should
+-free the buffer with `free' when you no longer need it.
+-
+- Here is an example of using the `a' flag with the `%[...]'
+-conversion specification to read a "variable assignment" of the form
+-`VARIABLE = VALUE'.
+-
+- {
+- char *variable, *value;
+-
+- if (2 > scanf ("%a[a-zA-Z0-9] = %a[^\n]\n",
+- &variable, &value))
+- {
+- invalid_input_error ();
+- return 0;
+- }

+- ...
+- }

+-
+-Other Input Conversions
+------------------------
+-
+- This section describes the miscellaneous input conversions.
+-
+- The `%p' conversion is used to read a pointer value. It recognizes
+-the same syntax used by the `%p' output conversion for `printf' (*note
+-Other Output Conversions::); that is, a hexadecimal number just as the
+-`%x' conversion accepts. The corresponding argument should be of type
+-`void **'; that is, the address of a place to store a pointer.
+-
+- The resulting pointer value is not guaranteed to be valid if it was
+-not originally written during the same program execution that reads it
+-in.
+-
+- The `%n' conversion produces the number of characters read so far by
+-this call. The corresponding argument should be of type `int *'. This
+-conversion works in the same way as the `%n' conversion for `printf';
+-see *Note Other Output Conversions::, for an example.
+-
+- The `%n' conversion is the only mechanism for determining the
+-success of literal matches or conversions with suppressed assignments.
+-If the `%n' follows the locus of a matching failure, then no value is
+-stored for it since `scanf' returns before processing the `%n'. If you
+-store `-1' in that argument slot before calling `scanf', the presence
+-of `-1' after `scanf' indicates an error occurred before the `%n' was
+-reached.
+-
+- Finally, the `%%' conversion matches a literal `%' character in the
+-input stream, without using an argument. This conversion does not
+-permit any flags, field width, or type modifier to be specified.

+-Formatted Input Functions
+--------------------------
+-
+- Here are the descriptions of the functions for performing formatted
+-input. Prototypes for these functions are in the header file `stdio.h'.
+-
+- - Function: int scanf (const char *TEMPLATE, ...)
+- The `scanf' function reads formatted input from the stream `stdin'
+- under the control of the template string TEMPLATE. The optional
+- arguments are pointers to the places which receive the resulting
+- values.
+-
+- The return value is normally the number of successful assignments.
+- If an end-of-file condition is detected before any matches are
+- performed, including matches against whitespace and literal
+- characters in the template, then `EOF' is returned.
+-
+- - Function: int wscanf (const wchar_t *TEMPLATE, ...)
+- The `wscanf' function reads formatted input from the stream
+- `stdin' under the control of the template string TEMPLATE. The
+- optional arguments are pointers to the places which receive the
+- resulting values.
+-
+- The return value is normally the number of successful assignments.
+- If an end-of-file condition is detected before any matches are
+- performed, including matches against whitespace and literal
+- characters in the template, then `WEOF' is returned.
+-
+- - Function: int fscanf (FILE *STREAM, const char *TEMPLATE, ...)
+- This function is just like `scanf', except that the input is read
+- from the stream STREAM instead of `stdin'.
+-
+- - Function: int fwscanf (FILE *STREAM, const wchar_t *TEMPLATE, ...)
+- This function is just like `wscanf', except that the input is read
+- from the stream STREAM instead of `stdin'.
+-
+- - Function: int sscanf (const char *S, const char *TEMPLATE, ...)
+- This is like `scanf', except that the characters are taken from the
+- null-terminated string S instead of from a stream. Reaching the
+- end of the string is treated as an end-of-file condition.
+-
+- The behavior of this function is undefined if copying takes place
+- between objects that overlap--for example, if S is also given as
+- an argument to receive a string read under control of the `%s',
+- `%S', or `%[' conversion.
+-
+- - Function: int swscanf (const wchar_t *WS, const char *TEMPLATE, ...)
+- This is like `wscanf', except that the characters are taken from
+- the null-terminated string WS instead of from a stream. Reaching
+- the end of the string is treated as an end-of-file condition.
+-
+- The behavior of this function is undefined if copying takes place
+- between objects that overlap--for example, if WS is also given as
+- an argument to receive a string read under control of the `%s',
+- `%S', or `%[' conversion.

+-Variable Arguments Input Functions
+-----------------------------------
+-
+- The functions `vscanf' and friends are provided so that you can
+-define your own variadic `scanf'-like functions that make use of the
+-same internals as the built-in formatted output functions. These
+-functions are analogous to the `vprintf' series of output functions.
+-*Note Variable Arguments Output::, for important information on how to
+-use them.
+-
+- *Portability Note:* The functions listed in this section were
+-introduced in ISO C99 and were before available as GNU extensions.
+-
+- - Function: int vscanf (const char *TEMPLATE, va_list AP)
+- This function is similar to `scanf', but instead of taking a
+- variable number of arguments directly, it takes an argument list
+- pointer AP of type `va_list' (*note Variadic Functions::).
+-
+- - Function: int vwscanf (const wchar_t *TEMPLATE, va_list AP)
+- This function is similar to `wscanf', but instead of taking a
+- variable number of arguments directly, it takes an argument list
+- pointer AP of type `va_list' (*note Variadic Functions::).
+-
+- - Function: int vfscanf (FILE *STREAM, const char *TEMPLATE, va_list
+- AP)
+- This is the equivalent of `fscanf' with the variable argument list
+- specified directly as for `vscanf'.
+-
+- - Function: int vfwscanf (FILE *STREAM, const wchar_t *TEMPLATE,
+- va_list AP)
+- This is the equivalent of `fwscanf' with the variable argument list
+- specified directly as for `vwscanf'.
+-
+- - Function: int vsscanf (const char *S, const char *TEMPLATE, va_list
+- AP)
+- This is the equivalent of `sscanf' with the variable argument list
+- specified directly as for `vscanf'.
+-
+- - Function: int vswscanf (const wchar_t *S, const wchar_t *TEMPLATE,
+- va_list AP)
+- This is the equivalent of `swscanf' with the variable argument list
+- specified directly as for `vwscanf'.
+-
+- In GNU C, there is a special construct you can use to let the
+-compiler know that a function uses a `scanf'-style format string. Then
+-it can check the number and types of arguments in each call to the
+-function, and warn you when they do not match the format string. For
+-details, *Note Declaring Attributes of Functions: (gcc.info)Function

+-
+-End-Of-File and Errors
+-======================
+-
+- Many of the functions described in this chapter return the value of
+-the macro `EOF' to indicate unsuccessful completion of the operation.
+-Since `EOF' is used to report both end of file and random errors, it's
+-often better to use the `feof' function to check explicitly for end of
+-file and `ferror' to check for errors. These functions check
+-indicators that are part of the internal state of the stream object,
+-indicators set if the appropriate condition was detected by a previous
+-I/O operation on that stream.
+-
+- - Macro: int EOF
+- This macro is an integer value that is returned by a number of
+- narrow stream functions to indicate an end-of-file condition, or
+- some other error situation. With the GNU library, `EOF' is `-1'.
+- In other libraries, its value may be some other negative number.
+-
+- This symbol is declared in `stdio.h'.
+-
+- - Macro: int WEOF
+- This macro is an integer value that is returned by a number of wide
+- stream functions to indicate an end-of-file condition, or some
+- other error situation. With the GNU library, `WEOF' is `-1'. In
+- other libraries, its value may be some other negative number.
+-
+- This symbol is declared in `wchar.h'.
+-
+- - Function: int feof (FILE *STREAM)
+- The `feof' function returns nonzero if and only if the end-of-file
+- indicator for the stream STREAM is set.
+-
+- This symbol is declared in `stdio.h'.
+-
+- - Function: int feof_unlocked (FILE *STREAM)
+- The `feof_unlocked' function is equivalent to the `feof' function
+- except that it does not implicitly lock the stream.
+-
+- This function is a GNU extension.
+-
+- This symbol is declared in `stdio.h'.
+-
+- - Function: int ferror (FILE *STREAM)
+- The `ferror' function returns nonzero if and only if the error
+- indicator for the stream STREAM is set, indicating that an error
+- has occurred on a previous operation on the stream.
+-
+- This symbol is declared in `stdio.h'.
+-
+- - Function: int ferror_unlocked (FILE *STREAM)
+- The `ferror_unlocked' function is equivalent to the `ferror'
+- function except that it does not implicitly lock the stream.
+-
+- This function is a GNU extension.
+-
+- This symbol is declared in `stdio.h'.
+-
+- In addition to setting the error indicator associated with the
+-stream, the functions that operate on streams also set `errno' in the
+-same way as the corresponding low-level functions that operate on file
+-descriptors. For example, all of the functions that perform output to a
+-stream--such as `fputc', `printf', and `fflush'--are implemented in
+-terms of `write', and all of the `errno' error conditions defined for
+-`write' are meaningful for these functions. For more information about
+-the descriptor-level I/O functions, see *Note Low-Level I/O::.
+-
+-\1f
+-File: libc.info, Node: Error Recovery, Next: Binary Streams, Prev: EOF and Errors, Up: I/O on Streams
+-
+-Recovering from errors
+-======================
+-
+- You may explicitly clear the error and EOF flags with the `clearerr'
+-function.
+-
+- - Function: void clearerr (FILE *STREAM)
+- This function clears the end-of-file and error indicators for the
+- stream STREAM.
+-
+- The file positioning functions (*note File Positioning::) also
+- clear the end-of-file indicator for the stream.
+-
+- - Function: void clearerr_unlocked (FILE *STREAM)
+- The `clearerr_unlocked' function is equivalent to the `clearerr'
+- function except that it does not implicitly lock the stream.
+-
+- This function is a GNU extension.
+-
+- Note that it is _not_ correct to just clear the error flag and retry
+-a failed stream operation. After a failed write, any number of
+-characters since the last buffer flush may have been committed to the
+-file, while some buffered data may have been discarded. Merely retrying
+-can thus cause lost or repeated data.
+-
+- A failed read may leave the file pointer in an inappropriate
+-position for a second try. In both cases, you should seek to a known
+-position before retrying.
+-
+- Most errors that can happen are not recoverable -- a second try will
+-always fail again in the same way. So usually it is best to give up and
+-report the error to the user, rather than install complicated recovery
+-logic.
+-
+- One important exception is `EINTR' (*note Interrupted Primitives::).
+-Many stream I/O implementations will treat it as an ordinary error,
+-which can be quite inconvenient. You can avoid this hassle by
+-installing all signals with the `SA_RESTART' flag.
+-
+- For similar reasons, setting nonblocking I/O on a stream's file
+-descriptor is not usually advisable.

+-
+-Text and Binary Streams
+-=======================
+-
+- The GNU system and other POSIX-compatible operating systems organize
+-all files as uniform sequences of characters. However, some other
+-systems make a distinction between files containing text and files
+-containing binary data, and the input and output facilities of ISO C
+-provide for this distinction. This section tells you how to write
+-programs portable to such systems.
+-
+- When you open a stream, you can specify either a "text stream" or a
+-"binary stream". You indicate that you want a binary stream by
+-specifying the `b' modifier in the OPENTYPE argument to `fopen'; see
+-*Note Opening Streams::. Without this option, `fopen' opens the file
+-as a text stream.
+-
+- Text and binary streams differ in several ways:
+-
+- * The data read from a text stream is divided into "lines" which are
+- terminated by newline (`'\n'') characters, while a binary stream is
+- simply a long series of characters. A text stream might on some
+- systems fail to handle lines more than 254 characters long
+- (including the terminating newline character).
+-
+- * On some systems, text files can contain only printing characters,
+- horizontal tab characters, and newlines, and so text streams may
+- not support other characters. However, binary streams can handle
+- any character value.
+-
+- * Space characters that are written immediately preceding a newline
+- character in a text stream may disappear when the file is read in
+- again.
+-
+- * More generally, there need not be a one-to-one mapping between
+- characters that are read from or written to a text stream, and the
+- characters in the actual file.
+-
+- Since a binary stream is always more capable and more predictable
+-than a text stream, you might wonder what purpose text streams serve.
+-Why not simply always use binary streams? The answer is that on these
+-operating systems, text and binary streams use different file formats,
+-and the only way to read or write "an ordinary file of text" that can
+-work with other text-oriented programs is through a text stream.
+-
+- In the GNU library, and on all POSIX systems, there is no difference
+-between text streams and binary streams. When you open a stream, you
+-get the same kind of stream regardless of whether you ask for binary.
+-This stream can handle any file content, and has none of the
+-restrictions that text streams sometimes have.
+-
+-\1f
+-File: libc.info, Node: File Positioning, Next: Portable Positioning, Prev: Binary Streams, Up: I/O on Streams
+-
+-File Positioning
+-================
+-
+- The "file position" of a stream describes where in the file the
+-stream is currently reading or writing. I/O on the stream advances the
+-file position through the file. In the GNU system, the file position is
+-represented as an integer, which counts the number of bytes from the
+-beginning of the file. *Note File Position::.
+-
+- During I/O to an ordinary disk file, you can change the file position
+-whenever you wish, so as to read or write any portion of the file. Some
+-other kinds of files may also permit this. Files which support changing
+-the file position are sometimes referred to as "random-access" files.
+-
+- You can use the functions in this section to examine or modify the
+-file position indicator associated with a stream. The symbols listed
+-below are declared in the header file `stdio.h'.
+-
+- - Function: long int ftell (FILE *STREAM)
+- This function returns the current file position of the stream
+- STREAM.
+-
+- This function can fail if the stream doesn't support file
+- positioning, or if the file position can't be represented in a
+- `long int', and possibly for other reasons as well. If a failure
+- occurs, a value of `-1' is returned.
+-
+- - Function: off_t ftello (FILE *STREAM)
+- The `ftello' function is similar to `ftell', except that it
+- returns a value of type `off_t'. Systems which support this type
+- use it to describe all file positions, unlike the POSIX
+- specification which uses a long int. The two are not necessarily
+- the same size. Therefore, using ftell can lead to problems if the
+- implementation is written on top of a POSIX compliant low-level
+- I/O implementation, and using `ftello' is preferable whenever it
+- is available.
+-
+- If this function fails it returns `(off_t) -1'. This can happen
+- due to missing support for file positioning or internal errors.
+- Otherwise the return value is the current file position.
+-
+- The function is an extension defined in the Unix Single
+- Specification version 2.
+-
+- When the sources are compiled with `_FILE_OFFSET_BITS == 64' on a
+- 32 bit system this function is in fact `ftello64'. I.e., the LFS
+- interface transparently replaces the old interface.
+-
+- - Function: off64_t ftello64 (FILE *STREAM)
+- This function is similar to `ftello' with the only difference that
+- the return value is of type `off64_t'. This also requires that the
+- stream STREAM was opened using either `fopen64', `freopen64', or
+- `tmpfile64' since otherwise the underlying file operations to
+- position the file pointer beyond the 2^31 bytes limit might fail.
+-
+- If the sources are compiled with `_FILE_OFFSET_BITS == 64' on a 32
+- bits machine this function is available under the name `ftello'
+- and so transparently replaces the old interface.
+-
+- - Function: int fseek (FILE *STREAM, long int OFFSET, int WHENCE)
+- The `fseek' function is used to change the file position of the
+- stream STREAM. The value of WHENCE must be one of the constants
+- `SEEK_SET', `SEEK_CUR', or `SEEK_END', to indicate whether the
+- OFFSET is relative to the beginning of the file, the current file
+- position, or the end of the file, respectively.
+-
+- This function returns a value of zero if the operation was
+- successful, and a nonzero value to indicate failure. A successful
+- call also clears the end-of-file indicator of STREAM and discards
+- any characters that were "pushed back" by the use of `ungetc'.
+-
+- `fseek' either flushes any buffered output before setting the file
+- position or else remembers it so it will be written later in its
+- proper place in the file.
+-
+- - Function: int fseeko (FILE *STREAM, off_t OFFSET, int WHENCE)
+- This function is similar to `fseek' but it corrects a problem with
+- `fseek' in a system with POSIX types. Using a value of type `long
+- int' for the offset is not compatible with POSIX. `fseeko' uses
+- the correct type `off_t' for the OFFSET parameter.
+-
+- For this reason it is a good idea to prefer `ftello' whenever it is
+- available since its functionality is (if different at all) closer
+- the underlying definition.
+-
+- The functionality and return value is the same as for `fseek'.
+-
+- The function is an extension defined in the Unix Single
+- Specification version 2.
+-
+- When the sources are compiled with `_FILE_OFFSET_BITS == 64' on a
+- 32 bit system this function is in fact `fseeko64'. I.e., the LFS
+- interface transparently replaces the old interface.
+-
+- - Function: int fseeko64 (FILE *STREAM, off64_t OFFSET, int WHENCE)
+- This function is similar to `fseeko' with the only difference that
+- the OFFSET parameter is of type `off64_t'. This also requires
+- that the stream STREAM was opened using either `fopen64',
+- `freopen64', or `tmpfile64' since otherwise the underlying file
+- operations to position the file pointer beyond the 2^31 bytes
+- limit might fail.
+-
+- If the sources are compiled with `_FILE_OFFSET_BITS == 64' on a 32
+- bits machine this function is available under the name `fseeko'
+- and so transparently replaces the old interface.
+-
+- *Portability Note:* In non-POSIX systems, `ftell', `ftello', `fseek'
+-and `fseeko' might work reliably only on binary streams. *Note Binary
+-Streams::.
+-
+- The following symbolic constants are defined for use as the WHENCE
+-argument to `fseek'. They are also used with the `lseek' function
+-(*note I/O Primitives::) and to specify offsets for file locks (*note
+-Control Operations::).
+-
+- - Macro: int SEEK_SET
+- This is an integer constant which, when used as the WHENCE
+- argument to the `fseek' or `fseeko' function, specifies that the
+- offset provided is relative to the beginning of the file.
+-
+- - Macro: int SEEK_CUR
+- This is an integer constant which, when used as the WHENCE
+- argument to the `fseek' or `fseeko' function, specifies that the
+- offset provided is relative to the current file position.
+-
+- - Macro: int SEEK_END
+- This is an integer constant which, when used as the WHENCE
+- argument to the `fseek' or `fseeko' function, specifies that the
+- offset provided is relative to the end of the file.
+-
+- - Function: void rewind (FILE *STREAM)
+- The `rewind' function positions the stream STREAM at the beginning
+- of the file. It is equivalent to calling `fseek' or `fseeko' on
+- the STREAM with an OFFSET argument of `0L' and a WHENCE argument
+- of `SEEK_SET', except that the return value is discarded and the
+- error indicator for the stream is reset.
+-
+- These three aliases for the `SEEK_...' constants exist for the sake
+-of compatibility with older BSD systems. They are defined in two
+-different header files: `fcntl.h' and `sys/file.h'.
+-
+-`L_SET'
+- An alias for `SEEK_SET'.
+-
+-`L_INCR'
+- An alias for `SEEK_CUR'.
+-
+-`L_XTND'
+- An alias for `SEEK_END'.

+-Introduction
+-************
+-
+- The C language provides no built-in facilities for performing such
+-common operations as input/output, memory management, string
+-manipulation, and the like. Instead, these facilities are defined in a
+-standard "library", which you compile and link with your programs.
+-
+- The GNU C library, described in this document, defines all of the
+-library functions that are specified by the ISO C standard, as well as
+-additional features specific to POSIX and other derivatives of the Unix
+-operating system, and extensions specific to the GNU system.
+-
+- The purpose of this manual is to tell you how to use the facilities
+-of the GNU library. We have mentioned which features belong to which
+-standards to help you identify things that are potentially non-portable
+-to other systems. But the emphasis in this manual is not on strict
+-portability.

+-Getting Started
+-===============
+-
+- This manual is written with the assumption that you are at least
+-somewhat familiar with the C programming language and basic programming
+-concepts. Specifically, familiarity with ISO standard C (*note ISO
+-C::), rather than "traditional" pre-ISO C dialects, is assumed.
+-
+- The GNU C library includes several "header files", each of which
+-provides definitions and declarations for a group of related facilities;
+-this information is used by the C compiler when processing your program.
+-For example, the header file `stdio.h' declares facilities for
+-performing input and output, and the header file `string.h' declares
+-string processing utilities. The organization of this manual generally
+-follows the same division as the header files.
+-
+- If you are reading this manual for the first time, you should read
+-all of the introductory material and skim the remaining chapters.
+-There are a _lot_ of functions in the GNU C library and it's not
+-realistic to expect that you will be able to remember exactly _how_ to
+-use each and every one of them. It's more important to become
+-generally familiar with the kinds of facilities that the library
+-provides, so that when you are writing your programs you can recognize
+-_when_ to make use of library functions, and _where_ in this manual you
+-can find more specific information about them.

+-Standard X3.159-1989--"ANSI C"' and later by the International
+-Standardization Organization (ISO): `ISO/IEC 9899:1990, "Programming
+-languages--C"'. We here refer to the standard as ISO C since this is
+-the more general standard in respect of ratification. The header files
+-and library facilities that make up the GNU library are a superset of
+-those specified by the ISO C standard.
+-
+- If you are concerned about strict adherence to the ISO C standard,
+-you should use the `-ansi' option when you compile your programs with
+-the GNU C compiler. This tells the compiler to define _only_ ISO
+-standard features from the library header files, unless you explicitly
+-ask for additional features. *Note Feature Test Macros::, for
+-information on how to do this.
+-
+- Being able to restrict the library to include only ISO C features is
+-important because ISO C puts limitations on what names can be defined
+-by the library implementation, and the GNU extensions don't fit these
+-limitations. *Note Reserved Names::, for more information about these
+-restrictions.
+-
+- This manual does not attempt to give you complete details on the
+-differences between ISO C and older dialects. It gives advice on how
+-to write programs to work portably under multiple C dialects, but does

+-POSIX (The Portable Operating System Interface)
+------------------------------------------------
+-
+- The GNU library is also compatible with the ISO "POSIX" family of
+-standards, known more formally as the "Portable Operating System
+-Interface for Computer Environments" (ISO/IEC 9945). They were also
+-published as ANSI/IEEE Std 1003. POSIX is derived mostly from various
+-versions of the Unix operating system.
+-
+- The library facilities specified by the POSIX standards are a
+-superset of those required by ISO C; POSIX specifies additional
+-features for ISO C functions, as well as specifying new additional
+-functions. In general, the additional requirements and functionality
+-defined by the POSIX standards are aimed at providing lower-level
+-support for a particular kind of operating system environment, rather
+-than general programming language support which can run in many diverse
+-operating system environments.
+-
+- The GNU C library implements all of the functions specified in
+-`ISO/IEC 9945-1:1996, the POSIX System Application Program Interface',
+-commonly referred to as POSIX.1. The primary extensions to the ISO C
+-facilities specified by this standard include file system interface
+-primitives (*note File System Interface::), device-specific terminal
+-control functions (*note Low-Level Terminal Interface::), and process
+-control functions (*note Processes::).
+-
+- Some facilities from `ISO/IEC 9945-2:1993, the POSIX Shell and
+-Utilities standard' (POSIX.2) are also implemented in the GNU library.
+-These include utilities for dealing with regular expressions and other
+-pattern matching facilities (*note Pattern Matching::).

+--------------

+- The GNU C library defines facilities from some versions of Unix which
+-are not formally standardized, specifically from the 4.2 BSD, 4.3 BSD,
+-and 4.4 BSD Unix systems (also known as "Berkeley Unix") and from
+-"SunOS" (a popular 4.2 BSD derivative that includes some Unix System V
+-functionality). These systems support most of the ISO C and POSIX
+-facilities, and 4.4 BSD and newer releases of SunOS in fact support
+-them all.
+-

+------------------------------------------
+-
+- The "System V Interface Description" (SVID) is a document describing
+-the AT&T Unix System V operating system. It is to some extent a
+-superset of the POSIX standard (*note POSIX::).
+-
+- The GNU C library defines most of the facilities required by the SVID
+-that are not also required by the ISO C or POSIX standards, for
+-compatibility with System V Unix and other Unix systems (such as
+-SunOS) which include these facilities. However, many of the more
+-obscure and less generally useful facilities required by the SVID are
+-not included. (In fact, Unix System V itself does not provide them
+-all.)
+-
+- The supported facilities from System V include the methods for
+-inter-process communication and shared memory, the `hsearch' and

+- The GNU C library complies to the X/Open Portability Guide, Issue
+-4.2, with all extensions common to XSI (X/Open System Interface)
+-compliant systems and also all X/Open UNIX extensions.
+-
+- The additions on top of POSIX are mainly derived from functionality

+-
+-Header Files
+-------------
+-
+- Libraries for use by C programs really consist of two parts: "header
+-files" that define types and macros and declare variables and
+-functions; and the actual library or "archive" that contains the
+-definitions of the variables and functions.
+-
+- (Recall that in C, a "declaration" merely provides information that
+-a function or variable exists and gives its type. For a function
+-declaration, information about the types of its arguments might be
+-provided as well. The purpose of declarations is to allow the compiler
+-to correctly process references to the declared variables and functions.
+-A "definition", on the other hand, actually allocates storage for a
+-variable or says what a function does.)
+-
+- In order to use the facilities in the GNU C library, you should be
+-sure that your program source files include the appropriate header
+-files. This is so that the compiler has declarations of these
+-facilities available and can correctly process references to them.
+-Once your program has been compiled, the linker resolves these
+-references to the actual definitions provided in the archive file.
+-
+- Header files are included into a program source file by the
+-`#include' preprocessor directive. The C language supports two forms
+-of this directive; the first,
+-
+- #include "HEADER"
+-
+-is typically used to include a header file HEADER that you write
+-yourself; this would contain definitions and declarations describing the
+-interfaces between the different parts of your particular application.
+-By contrast,
+-
+- #include <file.h>
+-
+-is typically used to include a header file `file.h' that contains
+-definitions and declarations for a standard library. This file would
+-normally be installed in a standard place by your system administrator.
+-You should use this second form for the C library header files.
+-
+- Typically, `#include' directives are placed at the top of the C
+-source file, before any other code. If you begin your source files with
+-some comments explaining what the code in the file does (a good idea),
+-put the `#include' directives immediately afterwards, following the
+-feature test macro definition (*note Feature Test Macros::).
+-
+- For more information about the use of header files and `#include'
+-directives, *note Header Files: (cpp.info)Header Files..
+-
+- The GNU C library provides several header files, each of which
+-contains the type and macro definitions and variable and function
+-declarations for a group of related facilities. This means that your
+-programs may need to include several header files, depending on exactly
+-which facilities you are using.
+-
+- Some library header files include other library header files
+-automatically. However, as a matter of programming style, you should
+-not rely on this; it is better to explicitly include all the header
+-files required for the library facilities you are using. The GNU C
+-library header files have been written in such a way that it doesn't
+-matter if a header file is accidentally included more than once;
+-including a header file a second time has no effect. Likewise, if your
+-program needs to include multiple header files, the order in which they
+-are included doesn't matter.
+-
+- *Compatibility Note:* Inclusion of standard header files in any
+-order and any number of times works in any ISO C implementation.
+-However, this has traditionally not been the case in many older C
+-implementations.
+-
+- Strictly speaking, you don't _have to_ include a header file to use
+-a function it declares; you could declare the function explicitly
+-yourself, according to the specifications in this manual. But it is
+-usually better to include the header file because it may define types
+-and macros that are not otherwise available and because it may define
+-more efficient macro replacements for some functions. It is also a sure
+-way to have the correct declaration.
+-
+-\1f
+-File: libc.info, Node: Macro Definitions, Next: Reserved Names, Prev: Header Files, Up: Using the Library
+-
+-Macro Definitions of Functions
+-------------------------------
+-
+- If we describe something as a function in this manual, it may have a
+-macro definition as well. This normally has no effect on how your
+-program runs--the macro definition does the same thing as the function
+-would. In particular, macro equivalents for library functions evaluate
+-arguments exactly once, in the same way that a function call would. The
+-main reason for these macro definitions is that sometimes they can
+-produce an inline expansion that is considerably faster than an actual
+-function call.
+-
+- Taking the address of a library function works even if it is also
+-defined as a macro. This is because, in this context, the name of the
+-function isn't followed by the left parenthesis that is syntactically
+-necessary to recognize a macro call.
+-
+- You might occasionally want to avoid using the macro definition of a
+-function--perhaps to make your program easier to debug. There are two
+-ways you can do this:
+-
+- * You can avoid a macro definition in a specific use by enclosing
+- the name of the function in parentheses. This works because the
+- name of the function doesn't appear in a syntactic context where
+- it is recognizable as a macro call.
+-
+- * You can suppress any macro definition for a whole source file by
+- using the `#undef' preprocessor directive, unless otherwise stated
+- explicitly in the description of that facility.
+-
+- For example, suppose the header file `stdlib.h' declares a function
+-named `abs' with
+-
+- extern int abs (int);
+-
+-and also provides a macro definition for `abs'. Then, in:
+-
+- #include <stdlib.h>
+- int f (int *i) { return abs (++*i); }
+-
+-the reference to `abs' might refer to either a macro or a function. On
+-the other hand, in each of the following examples the reference is to a
+-function and not a macro.
+-
+- #include <stdlib.h>
+- int g (int *i) { return (abs) (++*i); }
+-
+- #undef abs
+- int h (int *i) { return abs (++*i); }
+-
+- Since macro definitions that double for a function behave in exactly
+-the same way as the actual function version, there is usually no need
+-for any of these methods. In fact, removing macro definitions usually
+-just makes your program slower.
+-
+-\1f
+-File: libc.info, Node: Reserved Names, Next: Feature Test Macros, Prev: Macro Definitions, Up: Using the Library
+-
+-Reserved Names
+---------------
+-
+- The names of all library types, macros, variables and functions that
+-come from the ISO C standard are reserved unconditionally; your program
+-*may not* redefine these names. All other library names are reserved
+-if your program explicitly includes the header file that defines or
+-declares them. There are several reasons for these restrictions:
+-
+- * Other people reading your code could get very confused if you were
+- using a function named `exit' to do something completely different
+- from what the standard `exit' function does, for example.
+- Preventing this situation helps to make your programs easier to
+- understand and contributes to modularity and maintainability.
+-
+- * It avoids the possibility of a user accidentally redefining a
+- library function that is called by other library functions. If
+- redefinition were allowed, those other functions would not work
+- properly.
+-
+- * It allows the compiler to do whatever special optimizations it
+- pleases on calls to these functions, without the possibility that
+- they may have been redefined by the user. Some library
+- facilities, such as those for dealing with variadic arguments
+- (*note Variadic Functions::) and non-local exits (*note Non-Local
+- Exits::), actually require a considerable amount of cooperation on
+- the part of the C compiler, and with respect to the
+- implementation, it might be easier for the compiler to treat these
+- as built-in parts of the language.
+-
+- In addition to the names documented in this manual, reserved names
+-include all external identifiers (global functions and variables) that
+-begin with an underscore (`_') and all identifiers regardless of use
+-that begin with either two underscores or an underscore followed by a
+-capital letter are reserved names. This is so that the library and
+-header files can define functions, variables, and macros for internal
+-purposes without risk of conflict with names in user programs.
+-
+- Some additional classes of identifier names are reserved for future
+-extensions to the C language or the POSIX.1 environment. While using
+-these names for your own purposes right now might not cause a problem,
+-they do raise the possibility of conflict with future versions of the C
+-or POSIX standards, so you should avoid these names.
+-
+- * Names beginning with a capital `E' followed a digit or uppercase
+- letter may be used for additional error code names. *Note Error
+- Reporting::.
+-
+- * Names that begin with either `is' or `to' followed by a lowercase
+- letter may be used for additional character testing and conversion
+- functions. *Note Character Handling::.
+-
+- * Names that begin with `LC_' followed by an uppercase letter may be
+- used for additional macros specifying locale attributes. *Note
+- Locales::.
+-
+- * Names of all existing mathematics functions (*note Mathematics::)
+- suffixed with `f' or `l' are reserved for corresponding functions
+- that operate on `float' and `long double' arguments, respectively.
+-
+- * Names that begin with `SIG' followed by an uppercase letter are
+- reserved for additional signal names. *Note Standard Signals::.
+-
+- * Names that begin with `SIG_' followed by an uppercase letter are
+- reserved for additional signal actions. *Note Basic Signal
+- Handling::.
+-
+- * Names beginning with `str', `mem', or `wcs' followed by a
+- lowercase letter are reserved for additional string and array
+- functions. *Note String and Array Utilities::.
+-
+- * Names that end with `_t' are reserved for additional type names.
+-
+- In addition, some individual header files reserve names beyond those
+-that they actually define. You only need to worry about these
+-restrictions if your program includes that particular header file.
+-
+- * The header file `dirent.h' reserves names prefixed with `d_'.
+-
+- * The header file `fcntl.h' reserves names prefixed with `l_', `F_',
+- `O_', and `S_'.
+-
+- * The header file `grp.h' reserves names prefixed with `gr_'.
+-
+- * The header file `limits.h' reserves names suffixed with `_MAX'.
+-
+- * The header file `pwd.h' reserves names prefixed with `pw_'.
+-
+- * The header file `signal.h' reserves names prefixed with `sa_' and
+- `SA_'.
+-
+- * The header file `sys/stat.h' reserves names prefixed with `st_'
+- and `S_'.
+-
+- * The header file `sys/times.h' reserves names prefixed with `tms_'.
+-
+- * The header file `termios.h' reserves names prefixed with `c_',
+- `V', `I', `O', and `TC'; and names prefixed with `B' followed by a
+- digit.

+-
+-Feature Test Macros
+--------------------
+-
+- The exact set of features available when you compile a source file
+-is controlled by which "feature test macros" you define.
+-
+- If you compile your programs using `gcc -ansi', you get only the
+-ISO C library features, unless you explicitly request additional
+-features by defining one or more of the feature macros. *Note GNU CC
+-Command Options: (gcc.info)Invoking GCC, for more information about GCC
+-options.
+-
+- You should define these macros by using `#define' preprocessor
+-directives at the top of your source code files. These directives
+-_must_ come before any `#include' of a system header file. It is best
+-to make them the very first thing in the file, preceded only by
+-comments. You could also use the `-D' option to GCC, but it's better
+-if you make the source files indicate their own meaning in a
+-self-contained way.
+-
+- This system exists to allow the library to conform to multiple
+-standards. Although the different standards are often described as
+-supersets of each other, they are usually incompatible because larger
+-standards require functions with names that smaller ones reserve to the
+-user program. This is not mere pedantry -- it has been a problem in
+-practice. For instance, some non-GNU programs define functions named
+-`getline' that have nothing to do with this library's `getline'. They
+-would not be compilable if all features were enabled indiscriminately.
+-
+- This should not be used to verify that a program conforms to a
+-limited standard. It is insufficient for this purpose, as it will not
+-protect you from including header files outside the standard, or
+-relying on semantics undefined within the standard.
+-
+- - Macro: _POSIX_SOURCE
+- If you define this macro, then the functionality from the POSIX.1
+- standard (IEEE Standard 1003.1) is available, as well as all of the
+- ISO C facilities.
+-
+- The state of `_POSIX_SOURCE' is irrelevant if you define the macro
+- `_POSIX_C_SOURCE' to a positive integer.
+-
+- - Macro: _POSIX_C_SOURCE
+- Define this macro to a positive integer to control which POSIX
+- functionality is made available. The greater the value of this
+- macro, the more functionality is made available.
+-
+- If you define this macro to a value greater than or equal to `1',
+- then the functionality from the 1990 edition of the POSIX.1
+- standard (IEEE Standard 1003.1-1990) is made available.
+-
+- If you define this macro to a value greater than or equal to `2',
+- then the functionality from the 1992 edition of the POSIX.2
+- standard (IEEE Standard 1003.2-1992) is made available.
+-
+- If you define this macro to a value greater than or equal to
+- `199309L', then the functionality from the 1993 edition of the
+- POSIX.1b standard (IEEE Standard 1003.1b-1993) is made available.
+-
+- Greater values for `_POSIX_C_SOURCE' will enable future extensions.
+- The POSIX standards process will define these values as necessary,
+- and the GNU C Library should support them some time after they
+- become standardized. The 1996 edition of POSIX.1 (ISO/IEC 9945-1:
+- 1996) states that if you define `_POSIX_C_SOURCE' to a value
+- greater than or equal to `199506L', then the functionality from
+- the 1996 edition is made available.
+-
+- - Macro: _BSD_SOURCE
+- If you define this macro, functionality derived from 4.3 BSD Unix
+- is included as well as the ISO C, POSIX.1, and POSIX.2 material.
+-
+- Some of the features derived from 4.3 BSD Unix conflict with the
+- corresponding features specified by the POSIX.1 standard. If this
+- macro is defined, the 4.3 BSD definitions take precedence over the
+- POSIX definitions.
+-
+- Due to the nature of some of the conflicts between 4.3 BSD and
+- POSIX.1, you need to use a special "BSD compatibility library"
+- when linking programs compiled for BSD compatibility. This is
+- because some functions must be defined in two different ways, one
+- of them in the normal C library, and one of them in the
+- compatibility library. If your program defines `_BSD_SOURCE', you
+- must give the option `-lbsd-compat' to the compiler or linker when
+- linking the program, to tell it to find functions in this special
+- compatibility library before looking for them in the normal C
+- library.
+-
+- - Macro: _SVID_SOURCE
+- If you define this macro, functionality derived from SVID is
+- included as well as the ISO C, POSIX.1, POSIX.2, and X/Open
+- material.
+-
+- - Macro: _XOPEN_SOURCE
+- - Macro: _XOPEN_SOURCE_EXTENDED
+- If you define this macro, functionality described in the X/Open
+- Portability Guide is included. This is a superset of the POSIX.1
+- and POSIX.2 functionality and in fact `_POSIX_SOURCE' and
+- `_POSIX_C_SOURCE' are automatically defined.
+-
+- As the unification of all Unices, functionality only available in
+- BSD and SVID is also included.
+-
+- If the macro `_XOPEN_SOURCE_EXTENDED' is also defined, even more
+- functionality is available. The extra functions will make all
+- functions available which are necessary for the X/Open Unix brand.
+-
+- If the macro `_XOPEN_SOURCE' has the value 500 this includes all
+- functionality described so far plus some new definitions from the
+- Single Unix Specification, version 2.
+-
+- - Macro: _LARGEFILE_SOURCE
+- If this macro is defined some extra functions are available which
+- rectify a few shortcomings in all previous standards.
+- Specifically, the functions `fseeko' and `ftello' are available.
+- Without these functions the difference between the ISO C interface
+- (`fseek', `ftell') and the low-level POSIX interface (`lseek')
+- would lead to problems.
+-
+- This macro was introduced as part of the Large File Support
+- extension (LFS).
+-
+- - Macro: _LARGEFILE64_SOURCE
+- If you define this macro an additional set of functions is made
+- available which enables 32 bit systems to use files of sizes beyond
+- the usual limit of 2GB. This interface is not available if the
+- system does not support files that large. On systems where the
+- natural file size limit is greater than 2GB (i.e., on 64 bit
+- systems) the new functions are identical to the replaced functions.
+-
+- The new functionality is made available by a new set of types and
+- functions which replace the existing ones. The names of these new
+- objects contain `64' to indicate the intention, e.g., `off_t' vs.
+- `off64_t' and `fseeko' vs. `fseeko64'.
+-
+- This macro was introduced as part of the Large File Support
+- extension (LFS). It is a transition interface for the period when
+- 64 bit offsets are not generally used (see `_FILE_OFFSET_BITS').
+-
+- - Macro: _FILE_OFFSET_BITS
+- This macro determines which file system interface shall be used,
+- one replacing the other. Whereas `_LARGEFILE64_SOURCE' makes the
+- 64 bit interface available as an additional interface,
+- `_FILE_OFFSET_BITS' allows the 64 bit interface to replace the old
+- interface.
+-
+- If `_FILE_OFFSET_BITS' is undefined, or if it is defined to the
+- value `32', nothing changes. The 32 bit interface is used and
+- types like `off_t' have a size of 32 bits on 32 bit systems.
+-
+- If the macro is defined to the value `64', the large file interface
+- replaces the old interface. I.e., the functions are not made
+- available under different names (as they are with
+- `_LARGEFILE64_SOURCE'). Instead the old function names now
+- reference the new functions, e.g., a call to `fseeko' now indeed
+- calls `fseeko64'.
+-
+- This macro should only be selected if the system provides
+- mechanisms for handling large files. On 64 bit systems this macro
+- has no effect since the `*64' functions are identical to the
+- normal functions.
+-
+- This macro was introduced as part of the Large File Support
+- extension (LFS).
+-
+- - Macro: _ISOC99_SOURCE
+- Until the revised ISO C standard is widely adopted the new features
+- are not automatically enabled. The GNU libc nevertheless has a
+- complete implementation of the new standard and to enable the new
+- features the macro `_ISOC99_SOURCE' should be defined.
+-
+- - Macro: _GNU_SOURCE
+- If you define this macro, everything is included: ISO C89,
+- ISO C99, POSIX.1, POSIX.2, BSD, SVID, X/Open, LFS, and GNU
+- extensions. In the cases where POSIX.1 conflicts with BSD, the
+- POSIX definitions take precedence.
+-
+- If you want to get the full effect of `_GNU_SOURCE' but make the
+- BSD definitions take precedence over the POSIX definitions, use
+- this sequence of definitions:
+-
+- #define _GNU_SOURCE
+- #define _BSD_SOURCE
+- #define _SVID_SOURCE
+-
+- Note that if you do this, you must link your program with the BSD
+- compatibility library by passing the `-lbsd-compat' option to the
+- compiler or linker. *Note:* If you forget to do this, you may get
+- very strange errors at run time.
+-
+- - Macro: _REENTRANT
+- - Macro: _THREAD_SAFE
+- If you define one of these macros, reentrant versions of several
+- functions get declared. Some of the functions are specified in
+- POSIX.1c but many others are only available on a few other systems
+- or are unique to GNU libc. The problem is the delay in the
+- standardization of the thread safe C library interface.
+-
+- Unlike on some other systems, no special version of the C library
+- must be used for linking. There is only one version but while
+- compiling this it must have been specified to compile as thread
+- safe.
+-
+- We recommend you use `_GNU_SOURCE' in new programs. If you don't
+-specify the `-ansi' option to GCC and don't define any of these macros
+-explicitly, the effect is the same as defining `_POSIX_C_SOURCE' to 2
+-and `_POSIX_SOURCE', `_SVID_SOURCE', and `_BSD_SOURCE' to 1.
+-
+- When you define a feature test macro to request a larger class of
+-features, it is harmless to define in addition a feature test macro for
+-a subset of those features. For example, if you define
+-`_POSIX_C_SOURCE', then defining `_POSIX_SOURCE' as well has no effect.
+-Likewise, if you define `_GNU_SOURCE', then defining either
+-`_POSIX_SOURCE' or `_POSIX_C_SOURCE' or `_SVID_SOURCE' as well has no
+-effect.
+-
+- Note, however, that the features of `_BSD_SOURCE' are not a subset of
+-any of the other feature test macros supported. This is because it
+-defines BSD features that take precedence over the POSIX features that
+-are requested by the other macros. For this reason, defining
+-`_BSD_SOURCE' in addition to the other feature test macros does have an
+-effect: it causes the BSD features to take priority over the conflicting
+-POSIX features.

+-Error Reporting
+-***************
+-
+- Many functions in the GNU C library detect and report error
+-conditions, and sometimes your programs need to check for these error
+-conditions. For example, when you open an input file, you should
+-verify that the file was actually opened correctly, and print an error
+-message or take other appropriate action if the call to the library
+-function failed.
+-
+- This chapter describes how the error reporting facility works. Your
+-program should include the header file `errno.h' to use this facility.

+-
+-Checking for Errors
+-===================
+-
+- Most library functions return a special value to indicate that they
+-have failed. The special value is typically `-1', a null pointer, or a
+-constant such as `EOF' that is defined for that purpose. But this
+-return value tells you only that an error has occurred. To find out
+-what kind of error it was, you need to look at the error code stored in
+-the variable `errno'. This variable is declared in the header file
+-`errno.h'.
+-
+- - Variable: volatile int errno
+- The variable `errno' contains the system error number. You can
+- change the value of `errno'.
+-
+- Since `errno' is declared `volatile', it might be changed
+- asynchronously by a signal handler; see *Note Defining Handlers::.
+- However, a properly written signal handler saves and restores the
+- value of `errno', so you generally do not need to worry about this
+- possibility except when writing signal handlers.
+-
+- The initial value of `errno' at program startup is zero. Many
+- library functions are guaranteed to set it to certain nonzero
+- values when they encounter certain kinds of errors. These error
+- conditions are listed for each function. These functions do not
+- change `errno' when they succeed; thus, the value of `errno' after
+- a successful call is not necessarily zero, and you should not use
+- `errno' to determine _whether_ a call failed. The proper way to
+- do that is documented for each function. _If_ the call failed,
+- you can examine `errno'.
+-
+- Many library functions can set `errno' to a nonzero value as a
+- result of calling other library functions which might fail. You
+- should assume that any library function might alter `errno' when
+- the function returns an error.
+-
+- *Portability Note:* ISO C specifies `errno' as a "modifiable
+- lvalue" rather than as a variable, permitting it to be implemented
+- as a macro. For example, its expansion might involve a function
+- call, like `*_errno ()'. In fact, that is what it is on the GNU
+- system itself. The GNU library, on non-GNU systems, does whatever
+- is right for the particular system.
+-
+- There are a few library functions, like `sqrt' and `atan', that
+- return a perfectly legitimate value in case of an error, but also
+- set `errno'. For these functions, if you want to check to see
+- whether an error occurred, the recommended method is to set `errno'
+- to zero before calling the function, and then check its value
+- afterward.
+-
+- All the error codes have symbolic names; they are macros defined in
+-`errno.h'. The names start with `E' and an upper-case letter or digit;
+-you should consider names of this form to be reserved names. *Note
+-Reserved Names::.
+-
+- The error code values are all positive integers and are all distinct,
+-with one exception: `EWOULDBLOCK' and `EAGAIN' are the same. Since the
+-values are distinct, you can use them as labels in a `switch'
+-statement; just don't use both `EWOULDBLOCK' and `EAGAIN'. Your
+-program should not make any other assumptions about the specific values
+-of these symbolic constants.
+-
+- The value of `errno' doesn't necessarily have to correspond to any
+-of these macros, since some library functions might return other error
+-codes of their own for other situations. The only values that are
+-guaranteed to be meaningful for a particular library function are the
+-ones that this manual lists for that function.
+-
+- On non-GNU systems, almost any system call can return `EFAULT' if it
+-is given an invalid pointer as an argument. Since this could only
+-happen as a result of a bug in your program, and since it will not
+-happen on the GNU system, we have saved space by not mentioning
+-`EFAULT' in the descriptions of individual functions.
+-
+- In some Unix systems, many system calls can also return `EFAULT' if
+-given as an argument a pointer into the stack, and the kernel for some
+-obscure reason fails in its attempt to extend the stack. If this ever
+-happens, you should probably try using statically or dynamically
+-allocated memory instead of stack memory on that system.

+-
+-Portable File-Position Functions
+-================================
+-
+- On the GNU system, the file position is truly a character count. You
+-can specify any character count value as an argument to `fseek' or
+-`fseeko' and get reliable results for any random access file. However,
+-some ISO C systems do not represent file positions in this way.
+-
+- On some systems where text streams truly differ from binary streams,
+-it is impossible to represent the file position of a text stream as a
+-count of characters from the beginning of the file. For example, the
+-file position on some systems must encode both a record offset within
+-the file, and a character offset within the record.
+-
+- As a consequence, if you want your programs to be portable to these
+-systems, you must observe certain rules:
+-
+- * The value returned from `ftell' on a text stream has no predictable
+- relationship to the number of characters you have read so far.
+- The only thing you can rely on is that you can use it subsequently
+- as the OFFSET argument to `fseek' or `fseeko' to move back to the
+- same file position.
+-
+- * In a call to `fseek' or `fseeko' on a text stream, either the
+- OFFSET must be zero, or WHENCE must be `SEEK_SET' and and the
+- OFFSET must be the result of an earlier call to `ftell' on the
+- same stream.
+-
+- * The value of the file position indicator of a text stream is
+- undefined while there are characters that have been pushed back
+- with `ungetc' that haven't been read or discarded. *Note
+- Unreading::.
+-
+- But even if you observe these rules, you may still have trouble for
+-long files, because `ftell' and `fseek' use a `long int' value to
+-represent the file position. This type may not have room to encode all
+-the file positions in a large file. Using the `ftello' and `fseeko'
+-functions might help here since the `off_t' type is expected to be able
+-to hold all file position values but this still does not help to handle
+-additional information which must be associated with a file position.
+-
+- So if you do want to support systems with peculiar encodings for the
+-file positions, it is better to use the functions `fgetpos' and
+-`fsetpos' instead. These functions represent the file position using
+-the data type `fpos_t', whose internal representation varies from
+-system to system.
+-
+- These symbols are declared in the header file `stdio.h'.
+-
+- - Data Type: fpos_t
+- This is the type of an object that can encode information about the
+- file position of a stream, for use by the functions `fgetpos' and
+- `fsetpos'.
+-
+- In the GNU system, `fpos_t' is an opaque data structure that
+- contains internal data to represent file offset and conversion
+- state information. In other systems, it might have a different
+- internal representation.
+-
+- When compiling with `_FILE_OFFSET_BITS == 64' on a 32 bit machine
+- this type is in fact equivalent to `fpos64_t' since the LFS
+- interface transparently replaces the old interface.
+-
+- - Data Type: fpos64_t
+- This is the type of an object that can encode information about the
+- file position of a stream, for use by the functions `fgetpos64' and
+- `fsetpos64'.
+-
+- In the GNU system, `fpos64_t' is an opaque data structure that
+- contains internal data to represent file offset and conversion
+- state information. In other systems, it might have a different
+- internal representation.
+-
+- - Function: int fgetpos (FILE *STREAM, fpos_t *POSITION)
+- This function stores the value of the file position indicator for
+- the stream STREAM in the `fpos_t' object pointed to by POSITION.
+- If successful, `fgetpos' returns zero; otherwise it returns a
+- nonzero value and stores an implementation-defined positive value
+- in `errno'.
+-
+- When the sources are compiled with `_FILE_OFFSET_BITS == 64' on a
+- 32 bit system the function is in fact `fgetpos64'. I.e., the LFS
+- interface transparently replaces the old interface.
+-
+- - Function: int fgetpos64 (FILE *STREAM, fpos64_t *POSITION)
+- This function is similar to `fgetpos' but the file position is
+- returned in a variable of type `fpos64_t' to which POSITION points.
+-
+- If the sources are compiled with `_FILE_OFFSET_BITS == 64' on a 32
+- bits machine this function is available under the name `fgetpos'
+- and so transparently replaces the old interface.
+-
+- - Function: int fsetpos (FILE *STREAM, const fpos_t *POSITION)
+- This function sets the file position indicator for the stream
+- STREAM to the position POSITION, which must have been set by a
+- previous call to `fgetpos' on the same stream. If successful,
+- `fsetpos' clears the end-of-file indicator on the stream, discards
+- any characters that were "pushed back" by the use of `ungetc', and
+- returns a value of zero. Otherwise, `fsetpos' returns a nonzero
+- value and stores an implementation-defined positive value in
+- `errno'.
+-
+- When the sources are compiled with `_FILE_OFFSET_BITS == 64' on a
+- 32 bit system the function is in fact `fsetpos64'. I.e., the LFS
+- interface transparently replaces the old interface.
+-
+- - Function: int fsetpos64 (FILE *STREAM, const fpos64_t *POSITION)
+- This function is similar to `fsetpos' but the file position used
+- for positioning is provided in a variable of type `fpos64_t' to
+- which POSITION points.
+-
+- If the sources are compiled with `_FILE_OFFSET_BITS == 64' on a 32
+- bits machine this function is available under the name `fsetpos'
+- and so transparently replaces the old interface.

+-Stream Buffering
+-================
+-
+- Characters that are written to a stream are normally accumulated and
+-transmitted asynchronously to the file in a block, instead of appearing
+-as soon as they are output by the application program. Similarly,
+-streams often retrieve input from the host environment in blocks rather
+-than on a character-by-character basis. This is called "buffering".
+-
+- If you are writing programs that do interactive input and output
+-using streams, you need to understand how buffering works when you
+-design the user interface to your program. Otherwise, you might find
+-that output (such as progress or prompt messages) doesn't appear when
+-you intended it to, or displays some other unexpected behavior.
+-
+- This section deals only with controlling when characters are
+-transmitted between the stream and the file or device, and _not_ with
+-how things like echoing, flow control, and the like are handled on
+-specific classes of devices. For information on common control
+-operations on terminal devices, see *Note Low-Level Terminal
+-Interface::.
+-
+- You can bypass the stream buffering facilities altogether by using
+-the low-level input and output functions that operate on file
+-descriptors instead. *Note Low-Level I/O::.

+-
+-Buffering Concepts
+-------------------
+-
+- There are three different kinds of buffering strategies:
+-
+- * Characters written to or read from an "unbuffered" stream are
+- transmitted individually to or from the file as soon as possible.
+-
+- * Characters written to a "line buffered" stream are transmitted to
+- the file in blocks when a newline character is encountered.
+-
+- * Characters written to or read from a "fully buffered" stream are
+- transmitted to or from the file in blocks of arbitrary size.
+-
+- Newly opened streams are normally fully buffered, with one
+-exception: a stream connected to an interactive device such as a
+-terminal is initially line buffered. *Note Controlling Buffering::,
+-for information on how to select a different kind of buffering.
+-Usually the automatic selection gives you the most convenient kind of
+-buffering for the file or device you open.
+-
+- The use of line buffering for interactive devices implies that output
+-messages ending in a newline will appear immediately--which is usually
+-what you want. Output that doesn't end in a newline might or might not
+-show up immediately, so if you want them to appear immediately, you
+-should flush buffered output explicitly with `fflush', as described in
+-*Note Flushing Buffers::.
+-
+-\1f
+-File: libc.info, Node: Flushing Buffers, Next: Controlling Buffering, Prev: Buffering Concepts, Up: Stream Buffering
+-
+-Flushing Buffers
+-----------------
+-
+- "Flushing" output on a buffered stream means transmitting all
+-accumulated characters to the file. There are many circumstances when
+-buffered output on a stream is flushed automatically:
+-
+- * When you try to do output and the output buffer is full.
+-
+- * When the stream is closed. *Note Closing Streams::.
+-
+- * When the program terminates by calling `exit'. *Note Normal
+- Termination::.
+-
+- * When a newline is written, if the stream is line buffered.
+-
+- * Whenever an input operation on _any_ stream actually reads data
+- from its file.
+-
+- If you want to flush the buffered output at another time, call
+-`fflush', which is declared in the header file `stdio.h'.
+-
+- - Function: int fflush (FILE *STREAM)
+- This function causes any buffered output on STREAM to be delivered
+- to the file. If STREAM is a null pointer, then `fflush' causes
+- buffered output on _all_ open output streams to be flushed.
+-
+- This function returns `EOF' if a write error occurs, or zero
+- otherwise.
+-
+- - Function: int fflush_unlocked (FILE *STREAM)
+- The `fflush_unlocked' function is equivalent to the `fflush'
+- function except that it does not implicitly lock the stream.
+-
+- The `fflush' function can be used to flush all streams currently
+-opened. While this is useful in some situations it does often more than
+-necessary since it might be done in situations when terminal input is
+-required and the program wants to be sure that all output is visible on
+-the terminal. But this means that only line buffered streams have to be
+-flushed. Solaris introduced a function especially for this. It was
+-always available in the GNU C library in some form but never officially
+-exported.
+-
+- - Function: void _flushlbf (void)
+- The `_flushlbf' function flushes all line buffered streams
+- currently opened.
+-
+- This function is declared in the `stdio_ext.h' header.
+-
+- *Compatibility Note:* Some brain-damaged operating systems have been
+-known to be so thoroughly fixated on line-oriented input and output
+-that flushing a line buffered stream causes a newline to be written!
+-Fortunately, this "feature" seems to be becoming less common. You do
+-not need to worry about this in the GNU system.
+-
+- In some situations it might be useful to not flush the output pending
+-for a stream but instead simply forget it. If transmission is costly
+-and the output is not needed anymore this is valid reasoning. In this
+-situation a non-standard function introduced in Solaris and available in
+-the GNU C library can be used.
+-
+- - Function: void __fpurge (FILE *STREAM)
+- The `__fpurge' function causes the buffer of the stream STREAM to
+- be emptied. If the stream is currently in read mode all input in
+- the buffer is lost. If the stream is in output mode the buffered
+- output is not written to the device (or whatever other underlying
+- storage) and the buffer the cleared.
+-
+- This function is declared in `stdio_ext.h'.
+-

+-File: libc.info, Node: Controlling Buffering, Prev: Flushing Buffers, Up: Stream Buffering
+-
+-Controlling Which Kind of Buffering
+------------------------------------
+-
+- After opening a stream (but before any other operations have been
+-performed on it), you can explicitly specify what kind of buffering you
+-want it to have using the `setvbuf' function.
+-
+- The facilities listed in this section are declared in the header
+-file `stdio.h'.
+-
+- - Function: int setvbuf (FILE *STREAM, char *BUF, int MODE, size_t
+- SIZE)
+- This function is used to specify that the stream STREAM should
+- have the buffering mode MODE, which can be either `_IOFBF' (for
+- full buffering), `_IOLBF' (for line buffering), or `_IONBF' (for
+- unbuffered input/output).
+-
+- If you specify a null pointer as the BUF argument, then `setvbuf'
+- allocates a buffer itself using `malloc'. This buffer will be
+- freed when you close the stream.
+-
+- Otherwise, BUF should be a character array that can hold at least
+- SIZE characters. You should not free the space for this array as
+- long as the stream remains open and this array remains its buffer.
+- You should usually either allocate it statically, or `malloc'
+- (*note Unconstrained Allocation::) the buffer. Using an automatic
+- array is not a good idea unless you close the file before exiting
+- the block that declares the array.
+-
+- While the array remains a stream buffer, the stream I/O functions
+- will use the buffer for their internal purposes. You shouldn't
+- try to access the values in the array directly while the stream is
+- using it for buffering.
+-
+- The `setvbuf' function returns zero on success, or a nonzero value
+- if the value of MODE is not valid or if the request could not be
+- honored.
+-
+- - Macro: int _IOFBF
+- The value of this macro is an integer constant expression that can
+- be used as the MODE argument to the `setvbuf' function to specify
+- that the stream should be fully buffered.
+-
+- - Macro: int _IOLBF
+- The value of this macro is an integer constant expression that can
+- be used as the MODE argument to the `setvbuf' function to specify
+- that the stream should be line buffered.
+-
+- - Macro: int _IONBF
+- The value of this macro is an integer constant expression that can
+- be used as the MODE argument to the `setvbuf' function to specify
+- that the stream should be unbuffered.
+-
+- - Macro: int BUFSIZ
+- The value of this macro is an integer constant expression that is
+- good to use for the SIZE argument to `setvbuf'. This value is
+- guaranteed to be at least `256'.
+-
+- The value of `BUFSIZ' is chosen on each system so as to make stream
+- I/O efficient. So it is a good idea to use `BUFSIZ' as the size
+- for the buffer when you call `setvbuf'.
+-
+- Actually, you can get an even better value to use for the buffer
+- size by means of the `fstat' system call: it is found in the
+- `st_blksize' field of the file attributes. *Note Attribute
+- Meanings::.
+-
+- Sometimes people also use `BUFSIZ' as the allocation size of
+- buffers used for related purposes, such as strings used to receive
+- a line of input with `fgets' (*note Character Input::). There is
+- no particular reason to use `BUFSIZ' for this instead of any other
+- integer, except that it might lead to doing I/O in chunks of an
+- efficient size.
+-
+- - Function: void setbuf (FILE *STREAM, char *BUF)
+- If BUF is a null pointer, the effect of this function is
+- equivalent to calling `setvbuf' with a MODE argument of `_IONBF'.
+- Otherwise, it is equivalent to calling `setvbuf' with BUF, and a
+- MODE of `_IOFBF' and a SIZE argument of `BUFSIZ'.
+-
+- The `setbuf' function is provided for compatibility with old code;
+- use `setvbuf' in all new programs.
+-
+- - Function: void setbuffer (FILE *STREAM, char *BUF, size_t SIZE)
+- If BUF is a null pointer, this function makes STREAM unbuffered.
+- Otherwise, it makes STREAM fully buffered using BUF as the buffer.
+- The SIZE argument specifies the length of BUF.
+-
+- This function is provided for compatibility with old BSD code. Use
+- `setvbuf' instead.
+-
+- - Function: void setlinebuf (FILE *STREAM)
+- This function makes STREAM be line buffered, and allocates the
+- buffer for you.
+-
+- This function is provided for compatibility with old BSD code. Use
+- `setvbuf' instead.
+-
+- It is possible to query whether a given stream is line buffered or
+-not using a non-standard function introduced in Solaris and available
+-in the GNU C library.
+-
+- - Function: int __flbf (FILE *STREAM)
+- The `__flbf' function will return a nonzero value in case the
+- stream STREAM is line buffered. Otherwise the return value is
+- zero.
+-
+- This function is declared in the `stdio_ext.h' header.
+-
+- Two more extensions allow to determine the size of the buffer and how
+-much of it is used. These functions were also introduced in Solaris.
+-
+- - Function: size_t __fbufsize (FILE *STREAM)
+- The `__fbufsize' function return the size of the buffer in the
+- stream STREAM. This value can be used to optimize the use of the
+- stream.
+-
+- This function is declared in the `stdio_ext.h' header.
+-
+- - Function: size_t __fpending (FILE *STREAM) The `__fpending'
+- function returns the number of bytes currently in the output
+- buffer. For wide-oriented stream the measuring unit is wide
+- characters. This function should not be used on buffers in read
+- mode or opened read-only.
+-
+- This function is declared in the `stdio_ext.h' header.

+-Other Kinds of Streams
+-======================
+-
+- The GNU library provides ways for you to define additional kinds of
+-streams that do not necessarily correspond to an open file.
+-
+- One such type of stream takes input from or writes output to a

+-String Streams
+---------------
+-
+- The `fmemopen' and `open_memstream' functions allow you to do I/O to
+-a string or memory buffer. These facilities are declared in `stdio.h'.
+-
+- - Function: FILE * fmemopen (void *BUF, size_t SIZE, const char
+- *OPENTYPE)
+- This function opens a stream that allows the access specified by
+- the OPENTYPE argument, that reads from or writes to the buffer
+- specified by the argument BUF. This array must be at least SIZE
+- bytes long.
+-
+- If you specify a null pointer as the BUF argument, `fmemopen'
+- dynamically allocates an array SIZE bytes long (as with `malloc';
+- *note Unconstrained Allocation::). This is really only useful if
+- you are going to write things to the buffer and then read them back
+- in again, because you have no way of actually getting a pointer to
+- the buffer (for this, try `open_memstream', below). The buffer is
+- freed when the stream is closed.
+-
+- The argument OPENTYPE is the same as in `fopen' (*note Opening
+- Streams::). If the OPENTYPE specifies append mode, then the
+- initial file position is set to the first null character in the
+- buffer. Otherwise the initial file position is at the beginning
+- of the buffer.
+-
+- When a stream open for writing is flushed or closed, a null
+- character (zero byte) is written at the end of the buffer if it
+- fits. You should add an extra byte to the SIZE argument to
+- account for this. Attempts to write more than SIZE bytes to the
+- buffer result in an error.
+-
+- For a stream open for reading, null characters (zero bytes) in the
+- buffer do not count as "end of file". Read operations indicate
+- end of file only when the file position advances past SIZE bytes.
+- So, if you want to read characters from a null-terminated string,
+- you should supply the length of the string as the SIZE argument.
+-
+- Here is an example of using `fmemopen' to create a stream for
+-reading from a string:
+-
+- #include <stdio.h>
+-
+- static char buffer[] = "foobar";
+-
+- int
+- main (void)
+- {
+- int ch;
+- FILE *stream;
+-
+- stream = fmemopen (buffer, strlen (buffer), "r");
+- while ((ch = fgetc (stream)) != EOF)
+- printf ("Got %c\n", ch);
+- fclose (stream);
+-
+- return 0;
+- }
+-
+- This program produces the following output:
+-
+- Got f
+- Got o
+- Got o
+- Got b
+- Got a
+- Got r
+-
+- - Function: FILE * open_memstream (char **PTR, size_t *SIZELOC)
+- This function opens a stream for writing to a buffer. The buffer
+- is allocated dynamically (as with `malloc'; *note Unconstrained
+- Allocation::) and grown as necessary.
+-
+- When the stream is closed with `fclose' or flushed with `fflush',
+- the locations PTR and SIZELOC are updated to contain the pointer
+- to the buffer and its size. The values thus stored remain valid
+- only as long as no further output on the stream takes place. If
+- you do more output, you must flush the stream again to store new
+- values before you use them again.
+-
+- A null character is written at the end of the buffer. This null
+- character is _not_ included in the size value stored at SIZELOC.
+-
+- You can move the stream's file position with `fseek' or `fseeko'
+- (*note File Positioning::). Moving the file position past the end
+- of the data already written fills the intervening space with
+- zeroes.
+-
+- Here is an example of using `open_memstream':
+-
+- #include <stdio.h>
+-
+- int
+- main (void)
+- {
+- char *bp;
+- size_t size;
+- FILE *stream;
+-
+- stream = open_memstream (&bp, &size);
+- fprintf (stream, "hello");
+- fflush (stream);
+- printf ("buf = `%s', size = %d\n", bp, size);
+- fprintf (stream, ", world");
+- fclose (stream);
+- printf ("buf = `%s', size = %d\n", bp, size);
+-
+- return 0;
+- }
+-
+- This program produces the following output:
+-
+- buf = `hello', size = 5
+- buf = `hello, world', size = 12

+-
+-Obstack Streams
+----------------
+-
+- You can open an output stream that puts it data in an obstack.
+-*Note Obstacks::.
+-
+- - Function: FILE * open_obstack_stream (struct obstack *OBSTACK)
+- This function opens a stream for writing data into the obstack
+- OBSTACK. This starts an object in the obstack and makes it grow
+- as data is written (*note Growing Objects::).
+-
+- Calling `fflush' on this stream updates the current size of the
+- object to match the amount of data that has been written. After a
+- call to `fflush', you can examine the object temporarily.
+-
+- You can move the file position of an obstack stream with `fseek' or
+- `fseeko' (*note File Positioning::). Moving the file position past
+- the end of the data written fills the intervening space with zeros.
+-
+- To make the object permanent, update the obstack with `fflush', and
+- then use `obstack_finish' to finalize the object and get its
+- address. The following write to the stream starts a new object in
+- the obstack, and later writes add to that object until you do
+- another `fflush' and `obstack_finish'.
+-
+- But how do you find out how long the object is? You can get the
+- length in bytes by calling `obstack_object_size' (*note Status of
+- an Obstack::), or you can null-terminate the object like this:
+-
+- obstack_1grow (OBSTACK, 0);
+-
+- Whichever one you do, you must do it _before_ calling
+- `obstack_finish'. (You can do both if you wish.)
+-
+- Here is a sample function that uses `open_obstack_stream':
+-
+- char *
+- make_message_string (const char *a, int b)
+- {
+- FILE *stream = open_obstack_stream (&message_obstack);
+- output_task (stream);
+- fprintf (stream, ": ");
+- fprintf (stream, a, b);
+- fprintf (stream, "\n");
+- fclose (stream);
+- obstack_1grow (&message_obstack, 0);
+- return obstack_finish (&message_obstack);

+-Programming Your Own Custom Streams
+------------------------------------
+-
+- This section describes how you can make a stream that gets input
+-from an arbitrary data source or writes output to an arbitrary data sink
+-programmed by you. We call these "custom streams". The functions and
+-types described here are all GNU extensions.
+-
+-* Menu:
+-
+-* Streams and Cookies:: The "cookie" records where to fetch or
+- store data that is read or written.
+-* Hook Functions:: How you should define the four "hook
+- functions" that a custom stream needs.
+-
+-\1f
+-File: libc.info, Node: Streams and Cookies, Next: Hook Functions, Up: Custom Streams
+-
+-Custom Streams and Cookies
+-..........................
+-
+- Inside every custom stream is a special object called the "cookie".
+-This is an object supplied by you which records where to fetch or store
+-the data read or written. It is up to you to define a data type to use
+-for the cookie. The stream functions in the library never refer
+-directly to its contents, and they don't even know what the type is;
+-they record its address with type `void *'.
+-
+- To implement a custom stream, you must specify _how_ to fetch or
+-store the data in the specified place. You do this by defining "hook
+-functions" to read, write, change "file position", and close the
+-stream. All four of these functions will be passed the stream's cookie
+-so they can tell where to fetch or store the data. The library
+-functions don't know what's inside the cookie, but your functions will
+-know.
+-
+- When you create a custom stream, you must specify the cookie pointer,
+-and also the four hook functions stored in a structure of type
+-`cookie_io_functions_t'.
+-
+- These facilities are declared in `stdio.h'.
+-
+- - Data Type: cookie_io_functions_t
+- This is a structure type that holds the functions that define the
+- communications protocol between the stream and its cookie. It has
+- the following members:
+-
+- `cookie_read_function_t *read'
+- This is the function that reads data from the cookie. If the
+- value is a null pointer instead of a function, then read
+- operations on this stream always return `EOF'.
+-
+- `cookie_write_function_t *write'
+- This is the function that writes data to the cookie. If the
+- value is a null pointer instead of a function, then data
+- written to the stream is discarded.
+-
+- `cookie_seek_function_t *seek'
+- This is the function that performs the equivalent of file
+- positioning on the cookie. If the value is a null pointer
+- instead of a function, calls to `fseek' or `fseeko' on this
+- stream can only seek to locations within the buffer; any
+- attempt to seek outside the buffer will return an `ESPIPE'
+- error.
+-
+- `cookie_close_function_t *close'
+- This function performs any appropriate cleanup on the cookie
+- when closing the stream. If the value is a null pointer
+- instead of a function, nothing special is done to close the
+- cookie when the stream is closed.
+-
+- - Function: FILE * fopencookie (void *COOKIE, const char *OPENTYPE,
+- cookie_io_functions_t IO-FUNCTIONS)
+- This function actually creates the stream for communicating with
+- the COOKIE using the functions in the IO-FUNCTIONS argument. The
+- OPENTYPE argument is interpreted as for `fopen'; see *Note Opening
+- Streams::. (But note that the "truncate on open" option is
+- ignored.) The new stream is fully buffered.
+-
+- The `fopencookie' function returns the newly created stream, or a
+- null pointer in case of an error.
+-

+-
+-Custom Stream Hook Functions
+-............................
+-
+- Here are more details on how you should define the four hook
+-functions that a custom stream needs.
+-
+- You should define the function to read data from the cookie as:
+-
+- ssize_t READER (void *COOKIE, char *BUFFER, size_t SIZE)
+-
+- This is very similar to the `read' function; see *Note I/O
+-Primitives::. Your function should transfer up to SIZE bytes into the
+-BUFFER, and return the number of bytes read, or zero to indicate
+-end-of-file. You can return a value of `-1' to indicate an error.
+-
+- You should define the function to write data to the cookie as:
+-
+- ssize_t WRITER (void *COOKIE, const char *BUFFER, size_t SIZE)
+-
+- This is very similar to the `write' function; see *Note I/O
+-Primitives::. Your function should transfer up to SIZE bytes from the
+-buffer, and return the number of bytes written. You can return a value
+-of `-1' to indicate an error.
+-
+- You should define the function to perform seek operations on the
+-cookie as:
+-
+- int SEEKER (void *COOKIE, fpos_t *POSITION, int WHENCE)
+-
+- For this function, the POSITION and WHENCE arguments are interpreted
+-as for `fgetpos'; see *Note Portable Positioning::. In the GNU
+-library, `fpos_t' is equivalent to `off_t' or `long int', and simply
+-represents the number of bytes from the beginning of the file.
+-
+- After doing the seek operation, your function should store the
+-resulting file position relative to the beginning of the file in
+-POSITION. Your function should return a value of `0' on success and
+-`-1' to indicate an error.
+-
+- You should define the function to do cleanup operations on the cookie
+-appropriate for closing the stream as:
+-
+- int CLEANER (void *COOKIE)
+-
+- Your function should return `-1' to indicate an error, and `0'
+-otherwise.
+-
+- - Data Type: cookie_read_function
+- This is the data type that the read function for a custom stream
+- should have. If you declare the function as shown above, this is
+- the type it will have.
+-
+- - Data Type: cookie_write_function
+- The data type of the write function for a custom stream.
+-
+- - Data Type: cookie_seek_function
+- The data type of the seek function for a custom stream.
+-
+- - Data Type: cookie_close_function
+- The data type of the close function for a custom stream.

+-Formatted Messages
+-==================
+-
+- On systems which are based on System V messages of programs
+-(especially the system tools) are printed in a strict form using the
+-`fmtmsg' function. The uniformity sometimes helps the user to
+-interpret messages and the strictness tests of the `fmtmsg' function
+-ensure that the programmer follows some minimal requirements.

+-
+-Printing Formatted Messages
+----------------------------
+-
+- Messages can be printed to standard error and/or to the console. To
+-select the destination the programmer can use the following two values,
+-bitwise OR combined if wanted, for the CLASSIFICATION parameter of
+-`fmtmsg':
+-
+-`MM_PRINT'
+- Display the message in standard error.
+-
+-`MM_CONSOLE'
+- Display the message on the system console.
+-
+- The erroneous piece of the system can be signalled by exactly one of
+-the following values which also is bitwise ORed with the CLASSIFICATION
+-parameter to `fmtmsg':
+-
+-`MM_HARD'
+- The source of the condition is some hardware.
+-
+-`MM_SOFT'
+- The source of the condition is some software.
+-
+-`MM_FIRM'
+- The source of the condition is some firmware.
+-
+- A third component of the CLASSIFICATION parameter to `fmtmsg' can
+-describe the part of the system which detects the problem. This is
+-done by using exactly one of the following values:
+-
+-`MM_APPL'
+- The erroneous condition is detected by the application.
+-
+-`MM_UTIL'
+- The erroneous condition is detected by a utility.
+-
+-`MM_OPSYS'
+- The erroneous condition is detected by the operating system.
+-
+- A last component of CLASSIFICATION can signal the results of this
+-message. Exactly one of the following values can be used:
+-
+-`MM_RECOVER'
+- It is a recoverable error.
+-
+-`MM_NRECOV'
+- It is a non-recoverable error.
+-
+- - Function: int fmtmsg (long int CLASSIFICATION, const char *LABEL,
+- int SEVERITY, const char *TEXT, const char *ACTION, const
+- char *TAG)
+- Display a message described by its parameters on the device(s)
+- specified in the CLASSIFICATION parameter. The LABEL parameter
+- identifies the source of the message. The string should consist
+- of two colon separated parts where the first part has not more
+- than 10 and the second part not more than 14 characters. The TEXT
+- parameter describes the condition of the error, the ACTION
+- parameter possible steps to recover from the error and the TAG
+- parameter is a reference to the online documentation where more
+- information can be found. It should contain the LABEL value and a
+- unique identification number.
+-
+- Each of the parameters can be a special value which means this
+- value is to be omitted. The symbolic names for these values are:
+-
+- `MM_NULLLBL'
+- Ignore LABEL parameter.
+-
+- `MM_NULLSEV'
+- Ignore SEVERITY parameter.
+-
+- `MM_NULLMC'
+- Ignore CLASSIFICATION parameter. This implies that nothing is
+- actually printed.
+-
+- `MM_NULLTXT'
+- Ignore TEXT parameter.
+-
+- `MM_NULLACT'
+- Ignore ACTION parameter.
+-
+- `MM_NULLTAG'
+- Ignore TAG parameter.
+-
+- There is another way certain fields can be omitted from the output
+- to standard error. This is described below in the description of
+- environment variables influencing the behavior.
+-
+- The SEVERITY parameter can have one of the values in the following
+- table:
+-
+- `MM_NOSEV'
+- Nothing is printed, this value is the same as `MM_NULLSEV'.
+-
+- `MM_HALT'
+- This value is printed as `HALT'.
+-
+- `MM_ERROR'
+- This value is printed as `ERROR'.
+-
+- `MM_WARNING'
+- This value is printed as `WARNING'.
+-
+- `MM_INFO'
+- This value is printed as `INFO'.
+-
+- The numeric value of these five macros are between `0' and `4'.
+- Using the environment variable `SEV_LEVEL' or using the
+- `addseverity' function one can add more severity levels with their
+- corresponding string to print. This is described below (*note
+- Adding Severity Classes::).
+-
+- If no parameter is ignored the output looks like this:
+-
+- LABEL: SEVERITY-STRING: TEXT
+- TO FIX: ACTION TAG
+-
+- The colons, new line characters and the `TO FIX' string are
+- inserted if necessary, i.e., if the corresponding parameter is not
+- ignored.
+-
+- This function is specified in the X/Open Portability Guide. It is
+- also available on all systems derived from System V.
+-
+- The function returns the value `MM_OK' if no error occurred. If
+- only the printing to standard error failed, it returns `MM_NOMSG'.
+- If printing to the console fails, it returns `MM_NOCON'. If
+- nothing is printed `MM_NOTOK' is returned. Among situations where
+- all outputs fail this last value is also returned if a parameter
+- value is incorrect.
+-
+- There are two environment variables which influence the behavior of
+-`fmtmsg'. The first is `MSGVERB'. It is used to control the output
+-actually happening on standard error (_not_ the console output). Each
+-of the five fields can explicitly be enabled. To do this the user has
+-to put the `MSGVERB' variable with a format like the following in the
+-environment before calling the `fmtmsg' function the first time:
+-
+- MSGVERB=KEYWORD[:KEYWORD[:...]]
+-
+- Valid KEYWORDs are `label', `severity', `text', `action', and `tag'.
+-If the environment variable is not given or is the empty string, a not
+-supported keyword is given or the value is somehow else invalid, no
+-part of the message is masked out.
+-
+- The second environment variable which influences the behavior of
+-`fmtmsg' is `SEV_LEVEL'. This variable and the change in the behavior
+-of `fmtmsg' is not specified in the X/Open Portability Guide. It is
+-available in System V systems, though. It can be used to introduce new
+-severity levels. By default, only the five severity levels described
+-above are available. Any other numeric value would make `fmtmsg' print
+-nothing.
+-
+- If the user puts `SEV_LEVEL' with a format like
+-
+- SEV_LEVEL=[DESCRIPTION[:DESCRIPTION[:...]]]
+-
+-in the environment of the process before the first call to `fmtmsg',
+-where DESCRIPTION has a value of the form
+-
+- SEVERITY-KEYWORD,LEVEL,PRINTSTRING
+-
+- The SEVERITY-KEYWORD part is not used by `fmtmsg' but it has to be
+-present. The LEVEL part is a string representation of a number. The
+-numeric value must be a number greater than 4. This value must be used
+-in the SEVERITY parameter of `fmtmsg' to select this class. It is not
+-possible to overwrite any of the predefined classes. The PRINTSTRING
+-is the string printed when a message of this class is processed by
+-`fmtmsg' (see above, `fmtsmg' does not print the numeric value but
+-instead the string representation).
+-
+-\1f
+-File: libc.info, Node: Adding Severity Classes, Next: Example, Prev: Printing Formatted Messages, Up: Formatted Messages
+-
+-Adding Severity Classes
+------------------------
+-
+- There is another possibility to introduce severity classes besides
+-using the environment variable `SEV_LEVEL'. This simplifies the task of
+-introducing new classes in a running program. One could use the
+-`setenv' or `putenv' function to set the environment variable, but this
+-is toilsome.
+-
+- - Function: int addseverity (int SEVERITY, const char *STRING)
+- This function allows the introduction of new severity classes
+- which can be addressed by the SEVERITY parameter of the `fmtmsg'
+- function. The SEVERITY parameter of `addseverity' must match the
+- value for the parameter with the same name of `fmtmsg', and STRING
+- is the string printed in the actual messages instead of the numeric
+- value.
+-
+- If STRING is `NULL' the severity class with the numeric value
+- according to SEVERITY is removed.
+-
+- It is not possible to overwrite or remove one of the default
+- severity classes. All calls to `addseverity' with SEVERITY set to
+- one of the values for the default classes will fail.
+-
+- The return value is `MM_OK' if the task was successfully performed.
+- If the return value is `MM_NOTOK' something went wrong. This could
+- mean that no more memory is available or a class is not available
+- when it has to be removed.
+-
+- This function is not specified in the X/Open Portability Guide
+- although the `fmtsmg' function is. It is available on System V
+- systems.
+-
+-\1f
+-File: libc.info, Node: Example, Prev: Adding Severity Classes, Up: Formatted Messages
+-
+-How to use `fmtmsg' and `addseverity'
+--------------------------------------
+-
+- Here is a simple example program to illustrate the use of the both
+-functions described in this section.
+-
+- #include <fmtmsg.h>
+-
+- int
+- main (void)
+- {
+- addseverity (5, "NOTE2");
+- fmtmsg (MM_PRINT, "only1field", MM_INFO, "text2", "action2", "tag2");
+- fmtmsg (MM_PRINT, "UX:cat", 5, "invalid syntax", "refer to manual",
+- "UX:cat:001");
+- fmtmsg (MM_PRINT, "label:foo", 6, "text", "action", "tag");
+- return 0;
+- }
+-
+- The second call to `fmtmsg' illustrates a use of this function as it
+-usually occurs on System V systems, which heavily use this function.
+-It seems worthwhile to give a short explanation here of how this system
+-works on System V. The value of the LABEL field (`UX:cat') says that
+-the error occurred in the Unix program `cat'. The explanation of the
+-error follows and the value for the ACTION parameter is `"refer to
+-manual"'. One could be more specific here, if necessary. The TAG
+-field contains, as proposed above, the value of the string given for
+-the LABEL parameter, and additionally a unique ID (`001' in this case).
+-For a GNU environment this string could contain a reference to the
+-corresponding node in the Info page for the program.
+-
+-Running this program without specifying the `MSGVERB' and `SEV_LEVEL'
+-function produces the following output:
+-
+- UX:cat: NOTE2: invalid syntax
+- TO FIX: refer to manual UX:cat:001
+-
+- We see the different fields of the message and how the extra glue
+-(the colons and the `TO FIX' string) are printed. But only one of the
+-three calls to `fmtmsg' produced output. The first call does not print
+-anything because the LABEL parameter is not in the correct form. The
+-string must contain two fields, separated by a colon (*note Printing
+-Formatted Messages::). The third `fmtmsg' call produced no output
+-since the class with the numeric value `6' is not defined. Although a
+-class with numeric value `5' is also not defined by default, the call
+-to `addseverity' introduces it and the second call to `fmtmsg' produces
+-the above output.
+-
+- When we change the environment of the program to contain
+-`SEV_LEVEL=XXX,6,NOTE' when running it we get a different result:
+-
+- UX:cat: NOTE2: invalid syntax
+- TO FIX: refer to manual UX:cat:001
+- label:foo: NOTE: text
+- TO FIX: action tag
+-
+- Now the third call to `fmtmsg' produced some output and we see how
+-the string `NOTE' from the environment variable appears in the message.
+-
+- Now we can reduce the output by specifying which fields we are
+-interested in. If we additionally set the environment variable
+-`MSGVERB' to the value `severity:label:action' we get the following
+-output:
+-
+- UX:cat: NOTE2
+- TO FIX: refer to manual
+- label:foo: NOTE
+- TO FIX: action
+-
+-I.e., the output produced by the TEXT and the TAG parameters to
+-`fmtmsg' vanished. Please also note that now there is no colon after
+-the `NOTE' and `NOTE2' strings in the output. This is not necessary
+-since there is no more output on this line because the text is missing.

+-**********************
+-
+- This chapter describes functions for performing low-level
+-input/output operations on file descriptors. These functions include
+-the primitives for the higher-level I/O functions described in *Note
+-I/O on Streams::, as well as functions for performing low-level control
+-operations for which there are no equivalents on streams.
+-
+- Stream-level I/O is more flexible and usually more convenient;
+-therefore, programmers generally use the descriptor-level functions only
+-when necessary. These are some of the usual reasons:
+-
+- * For reading binary files in large chunks.
+-
+- * For reading an entire file into core before parsing it.
+-
+- * To perform operations other than data transfer, which can only be
+- done with a descriptor. (You can use `fileno' to get the
+- descriptor corresponding to a stream.)
+-
+- * To pass descriptors to a child process. (The child can create its
+- own stream to use a descriptor that it inherits, but cannot
+- inherit a stream directly.)

+-Opening and Closing Files
+-=========================
+-
+- This section describes the primitives for opening and closing files
+-using file descriptors. The `open' and `creat' functions are declared
+-in the header file `fcntl.h', while `close' is declared in `unistd.h'.
+-
+- - Function: int open (const char *FILENAME, int FLAGS[, mode_t MODE])
+- The `open' function creates and returns a new file descriptor for
+- the file named by FILENAME. Initially, the file position
+- indicator for the file is at the beginning of the file. The
+- argument MODE is used only when a file is created, but it doesn't
+- hurt to supply the argument in any case.
+-
+- The FLAGS argument controls how the file is to be opened. This is
+- a bit mask; you create the value by the bitwise OR of the
+- appropriate parameters (using the `|' operator in C). *Note File
+- Status Flags::, for the parameters available.
+-
+- The normal return value from `open' is a non-negative integer file
+- descriptor. In the case of an error, a value of -1 is returned
+- instead. In addition to the usual file name errors (*note File
+- Name Errors::), the following `errno' error conditions are defined
+- for this function:
+-
+- `EACCES'
+- The file exists but is not readable/writable as requested by
+- the FLAGS argument, the file does not exist and the directory
+- is unwritable so it cannot be created.
+-
+- `EEXIST'
+- Both `O_CREAT' and `O_EXCL' are set, and the named file
+- already exists.
+-
+- `EINTR'
+- The `open' operation was interrupted by a signal. *Note
+- Interrupted Primitives::.
+-
+- `EISDIR'
+- The FLAGS argument specified write access, and the file is a
+- directory.
+-
+- `EMFILE'
+- The process has too many files open. The maximum number of
+- file descriptors is controlled by the `RLIMIT_NOFILE'
+- resource limit; *note Limits on Resources::.
+-
+- `ENFILE'
+- The entire system, or perhaps the file system which contains
+- the directory, cannot support any additional open files at
+- the moment. (This problem cannot happen on the GNU system.)
+-
+- `ENOENT'
+- The named file does not exist, and `O_CREAT' is not specified.
+-
+- `ENOSPC'
+- The directory or file system that would contain the new file
+- cannot be extended, because there is no disk space left.
+-
+- `ENXIO'
+- `O_NONBLOCK' and `O_WRONLY' are both set in the FLAGS
+- argument, the file named by FILENAME is a FIFO (*note Pipes
+- and FIFOs::), and no process has the file open for reading.
+-
+- `EROFS'
+- The file resides on a read-only file system and any of
+- `O_WRONLY', `O_RDWR', and `O_TRUNC' are set in the FLAGS
+- argument, or `O_CREAT' is set and the file does not already
+- exist.
+-
+- If on a 32 bit machine the sources are translated with
+- `_FILE_OFFSET_BITS == 64' the function `open' returns a file
+- descriptor opened in the large file mode which enables the file
+- handling functions to use files up to 2^63 bytes in size and
+- offset from -2^63 to 2^63. This happens transparently for the user
+- since all of the lowlevel file handling functions are equally
+- replaced.
+-
+- This function is a cancellation point in multi-threaded programs.
+- This is a problem if the thread allocates some resources (like
+- memory, file descriptors, semaphores or whatever) at the time
+- `open' is called. If the thread gets canceled these resources
+- stay allocated until the program ends. To avoid this calls to
+- `open' should be protected using cancellation handlers.
+-
+- The `open' function is the underlying primitive for the `fopen'
+- and `freopen' functions, that create streams.
+-
+- - Function: int open64 (const char *FILENAME, int FLAGS[, mode_t MODE])
+- This function is similar to `open'. It returns a file descriptor
+- which can be used to access the file named by FILENAME. The only
+- difference is that on 32 bit systems the file is opened in the
+- large file mode. I.e., file length and file offsets can exceed 31
+- bits.
+-
+- When the sources are translated with `_FILE_OFFSET_BITS == 64' this
+- function is actually available under the name `open'. I.e., the
+- new, extended API using 64 bit file sizes and offsets transparently
+- replaces the old API.
+-
+- - Obsolete function: int creat (const char *FILENAME, mode_t MODE)
+- This function is obsolete. The call:
+-
+- creat (FILENAME, MODE)
+-
+- is equivalent to:
+-
+- open (FILENAME, O_WRONLY | O_CREAT | O_TRUNC, MODE)
+-
+- If on a 32 bit machine the sources are translated with
+- `_FILE_OFFSET_BITS == 64' the function `creat' returns a file
+- descriptor opened in the large file mode which enables the file
+- handling functions to use files up to 2^63 in size and offset from
+- -2^63 to 2^63. This happens transparently for the user since all
+- of the lowlevel file handling functions are equally replaced.
+-
+- - Obsolete function: int creat64 (const char *FILENAME, mode_t MODE)
+- This function is similar to `creat'. It returns a file descriptor
+- which can be used to access the file named by FILENAME. The only
+- the difference is that on 32 bit systems the file is opened in the
+- large file mode. I.e., file length and file offsets can exceed 31
+- bits.
+-
+- To use this file descriptor one must not use the normal operations
+- but instead the counterparts named `*64', e.g., `read64'.
+-
+- When the sources are translated with `_FILE_OFFSET_BITS == 64' this
+- function is actually available under the name `open'. I.e., the
+- new, extended API using 64 bit file sizes and offsets transparently
+- replaces the old API.
+-
+- - Function: int close (int FILEDES)
+- The function `close' closes the file descriptor FILEDES. Closing
+- a file has the following consequences:
+-
+- * The file descriptor is deallocated.
+-
+- * Any record locks owned by the process on the file are
+- unlocked.
+-
+- * When all file descriptors associated with a pipe or FIFO have
+- been closed, any unread data is discarded.
+-
+- This function is a cancellation point in multi-threaded programs.
+- This is a problem if the thread allocates some resources (like
+- memory, file descriptors, semaphores or whatever) at the time
+- `close' is called. If the thread gets canceled these resources
+- stay allocated until the program ends. To avoid this, calls to
+- `close' should be protected using cancellation handlers.
+-
+- The normal return value from `close' is 0; a value of -1 is
+- returned in case of failure. The following `errno' error
+- conditions are defined for this function:
+-
+- `EBADF'
+- The FILEDES argument is not a valid file descriptor.
+-
+- `EINTR'
+- The `close' call was interrupted by a signal. *Note
+- Interrupted Primitives::. Here is an example of how to
+- handle `EINTR' properly:
+-
+- TEMP_FAILURE_RETRY (close (desc));
+-
+- `ENOSPC'
+- `EIO'
+- `EDQUOT'
+- When the file is accessed by NFS, these errors from `write'
+- can sometimes not be detected until `close'. *Note I/O
+- Primitives::, for details on their meaning.
+-
+- Please note that there is _no_ separate `close64' function. This
+- is not necessary since this function does not determine nor depend
+- on the mode of the file. The kernel which performs the `close'
+- operation knows which mode the descriptor is used for and can
+- handle this situation.
+-
+- To close a stream, call `fclose' (*note Closing Streams::) instead
+-of trying to close its underlying file descriptor with `close'. This
+-flushes any buffered output and updates the stream object to indicate
+-that it is closed.

+-Input and Output Primitives
+-===========================
+-
+- This section describes the functions for performing primitive input
+-and output operations on file descriptors: `read', `write', and
+-`lseek'. These functions are declared in the header file `unistd.h'.
+-
+- - Data Type: ssize_t
+- This data type is used to represent the sizes of blocks that can be
+- read or written in a single operation. It is similar to `size_t',
+- but must be a signed type.
+-
+- - Function: ssize_t read (int FILEDES, void *BUFFER, size_t SIZE)
+- The `read' function reads up to SIZE bytes from the file with
+- descriptor FILEDES, storing the results in the BUFFER. (This is
+- not necessarily a character string, and no terminating null
+- character is added.)
+-
+- The return value is the number of bytes actually read. This might
+- be less than SIZE; for example, if there aren't that many bytes
+- left in the file or if there aren't that many bytes immediately
+- available. The exact behavior depends on what kind of file it is.
+- Note that reading less than SIZE bytes is not an error.
+-
+- A value of zero indicates end-of-file (except if the value of the
+- SIZE argument is also zero). This is not considered an error. If
+- you keep calling `read' while at end-of-file, it will keep
+- returning zero and doing nothing else.
+-
+- If `read' returns at least one character, there is no way you can
+- tell whether end-of-file was reached. But if you did reach the
+- end, the next read will return zero.
+-
+- In case of an error, `read' returns -1. The following `errno'
+- error conditions are defined for this function:
+-
+- `EAGAIN'
+- Normally, when no input is immediately available, `read'
+- waits for some input. But if the `O_NONBLOCK' flag is set
+- for the file (*note File Status Flags::), `read' returns
+- immediately without reading any data, and reports this error.
+-
+- *Compatibility Note:* Most versions of BSD Unix use a
+- different error code for this: `EWOULDBLOCK'. In the GNU
+- library, `EWOULDBLOCK' is an alias for `EAGAIN', so it
+- doesn't matter which name you use.
+-
+- On some systems, reading a large amount of data from a
+- character special file can also fail with `EAGAIN' if the
+- kernel cannot find enough physical memory to lock down the
+- user's pages. This is limited to devices that transfer with
+- direct memory access into the user's memory, which means it
+- does not include terminals, since they always use separate
+- buffers inside the kernel. This problem never happens in the
+- GNU system.
+-
+- Any condition that could result in `EAGAIN' can instead
+- result in a successful `read' which returns fewer bytes than
+- requested. Calling `read' again immediately would result in
+- `EAGAIN'.
+-
+- `EBADF'
+- The FILEDES argument is not a valid file descriptor, or is
+- not open for reading.
+-
+- `EINTR'
+- `read' was interrupted by a signal while it was waiting for
+- input. *Note Interrupted Primitives::. A signal will not
+- necessary cause `read' to return `EINTR'; it may instead
+- result in a successful `read' which returns fewer bytes than
+- requested.
+-
+- `EIO'
+- For many devices, and for disk files, this error code
+- indicates a hardware error.
+-
+- `EIO' also occurs when a background process tries to read
+- from the controlling terminal, and the normal action of
+- stopping the process by sending it a `SIGTTIN' signal isn't
+- working. This might happen if the signal is being blocked or
+- ignored, or because the process group is orphaned. *Note Job
+- Control::, for more information about job control, and *Note
+- Signal Handling::, for information about signals.
+-
+- Please note that there is no function named `read64'. This is not
+- necessary since this function does not directly modify or handle
+- the possibly wide file offset. Since the kernel handles this state
+- internally, the `read' function can be used for all cases.
+-
+- This function is a cancellation point in multi-threaded programs.
+- This is a problem if the thread allocates some resources (like
+- memory, file descriptors, semaphores or whatever) at the time
+- `read' is called. If the thread gets canceled these resources
+- stay allocated until the program ends. To avoid this, calls to
+- `read' should be protected using cancellation handlers.
+-
+- The `read' function is the underlying primitive for all of the
+- functions that read from streams, such as `fgetc'.
+-
+- - Function: ssize_t pread (int FILEDES, void *BUFFER, size_t SIZE,
+- off_t OFFSET)
+- The `pread' function is similar to the `read' function. The first
+- three arguments are identical, and the return values and error
+- codes also correspond.
+-
+- The difference is the fourth argument and its handling. The data
+- block is not read from the current position of the file descriptor
+- `filedes'. Instead the data is read from the file starting at
+- position OFFSET. The position of the file descriptor itself is
+- not affected by the operation. The value is the same as before
+- the call.
+-
+- When the source file is compiled with `_FILE_OFFSET_BITS == 64' the
+- `pread' function is in fact `pread64' and the type `off_t' has 64
+- bits, which makes it possible to handle files up to 2^63 bytes in
+- length.
+-
+- The return value of `pread' describes the number of bytes read.
+- In the error case it returns -1 like `read' does and the error
+- codes are also the same, with these additions:
+-
+- `EINVAL'
+- The value given for OFFSET is negative and therefore illegal.
+-
+- `ESPIPE'
+- The file descriptor FILEDES is associate with a pipe or a
+- FIFO and this device does not allow positioning of the file
+- pointer.
+-
+- The function is an extension defined in the Unix Single
+- Specification version 2.
+-
+- - Function: ssize_t pread64 (int FILEDES, void *BUFFER, size_t SIZE,
+- off64_t OFFSET)
+- This function is similar to the `pread' function. The difference
+- is that the OFFSET parameter is of type `off64_t' instead of
+- `off_t' which makes it possible on 32 bit machines to address
+- files larger than 2^31 bytes and up to 2^63 bytes. The file
+- descriptor `filedes' must be opened using `open64' since otherwise
+- the large offsets possible with `off64_t' will lead to errors with
+- a descriptor in small file mode.
+-
+- When the source file is compiled with `_FILE_OFFSET_BITS == 64' on
+- a 32 bit machine this function is actually available under the name
+- `pread' and so transparently replaces the 32 bit interface.
+-
+- - Function: ssize_t write (int FILEDES, const void *BUFFER, size_t
+- SIZE)
+- The `write' function writes up to SIZE bytes from BUFFER to the
+- file with descriptor FILEDES. The data in BUFFER is not
+- necessarily a character string and a null character is output like
+- any other character.
+-
+- The return value is the number of bytes actually written. This
+- may be SIZE, but can always be smaller. Your program should
+- always call `write' in a loop, iterating until all the data is
+- written.
+-
+- Once `write' returns, the data is enqueued to be written and can be
+- read back right away, but it is not necessarily written out to
+- permanent storage immediately. You can use `fsync' when you need
+- to be sure your data has been permanently stored before
+- continuing. (It is more efficient for the system to batch up
+- consecutive writes and do them all at once when convenient.
+- Normally they will always be written to disk within a minute or
+- less.) Modern systems provide another function `fdatasync' which
+- guarantees integrity only for the file data and is therefore
+- faster. You can use the `O_FSYNC' open mode to make `write' always
+- store the data to disk before returning; *note Operating Modes::.
+-
+- In the case of an error, `write' returns -1. The following
+- `errno' error conditions are defined for this function:
+-
+- `EAGAIN'
+- Normally, `write' blocks until the write operation is
+- complete. But if the `O_NONBLOCK' flag is set for the file
+- (*note Control Operations::), it returns immediately without
+- writing any data and reports this error. An example of a
+- situation that might cause the process to block on output is
+- writing to a terminal device that supports flow control,
+- where output has been suspended by receipt of a STOP
+- character.
+-
+- *Compatibility Note:* Most versions of BSD Unix use a
+- different error code for this: `EWOULDBLOCK'. In the GNU
+- library, `EWOULDBLOCK' is an alias for `EAGAIN', so it
+- doesn't matter which name you use.
+-
+- On some systems, writing a large amount of data from a
+- character special file can also fail with `EAGAIN' if the
+- kernel cannot find enough physical memory to lock down the
+- user's pages. This is limited to devices that transfer with
+- direct memory access into the user's memory, which means it
+- does not include terminals, since they always use separate
+- buffers inside the kernel. This problem does not arise in the
+- GNU system.
+-
+- `EBADF'
+- The FILEDES argument is not a valid file descriptor, or is
+- not open for writing.
+-
+- `EFBIG'
+- The size of the file would become larger than the
+- implementation can support.
+-
+- `EINTR'
+- The `write' operation was interrupted by a signal while it was
+- blocked waiting for completion. A signal will not
+- necessarily cause `write' to return `EINTR'; it may instead
+- result in a successful `write' which writes fewer bytes than
+- requested. *Note Interrupted Primitives::.
+-
+- `EIO'
+- For many devices, and for disk files, this error code
+- indicates a hardware error.
+-
+- `ENOSPC'
+- The device containing the file is full.
+-
+- `EPIPE'
+- This error is returned when you try to write to a pipe or
+- FIFO that isn't open for reading by any process. When this
+- happens, a `SIGPIPE' signal is also sent to the process; see
+- *Note Signal Handling::.
+-
+- Unless you have arranged to prevent `EINTR' failures, you should
+- check `errno' after each failing call to `write', and if the error
+- was `EINTR', you should simply repeat the call. *Note Interrupted
+- Primitives::. The easy way to do this is with the macro
+- `TEMP_FAILURE_RETRY', as follows:
+-
+- nbytes = TEMP_FAILURE_RETRY (write (desc, buffer, count));
+-
+- Please note that there is no function named `write64'. This is not
+- necessary since this function does not directly modify or handle
+- the possibly wide file offset. Since the kernel handles this state
+- internally the `write' function can be used for all cases.
+-
+- This function is a cancellation point in multi-threaded programs.
+- This is a problem if the thread allocates some resources (like
+- memory, file descriptors, semaphores or whatever) at the time
+- `write' is called. If the thread gets canceled these resources
+- stay allocated until the program ends. To avoid this, calls to
+- `write' should be protected using cancellation handlers.
+-
+- The `write' function is the underlying primitive for all of the
+- functions that write to streams, such as `fputc'.
+-
+- - Function: ssize_t pwrite (int FILEDES, const void *BUFFER, size_t
+- SIZE, off_t OFFSET)
+- The `pwrite' function is similar to the `write' function. The
+- first three arguments are identical, and the return values and
+- error codes also correspond.
+-
+- The difference is the fourth argument and its handling. The data
+- block is not written to the current position of the file descriptor
+- `filedes'. Instead the data is written to the file starting at
+- position OFFSET. The position of the file descriptor itself is
+- not affected by the operation. The value is the same as before
+- the call.
+-
+- When the source file is compiled with `_FILE_OFFSET_BITS == 64' the
+- `pwrite' function is in fact `pwrite64' and the type `off_t' has
+- 64 bits, which makes it possible to handle files up to 2^63 bytes
+- in length.
+-
+- The return value of `pwrite' describes the number of written bytes.
+- In the error case it returns -1 like `write' does and the error
+- codes are also the same, with these additions:
+-
+- `EINVAL'
+- The value given for OFFSET is negative and therefore illegal.
+-
+- `ESPIPE'
+- The file descriptor FILEDES is associated with a pipe or a
+- FIFO and this device does not allow positioning of the file
+- pointer.
+-
+- The function is an extension defined in the Unix Single
+- Specification version 2.
+-
+- - Function: ssize_t pwrite64 (int FILEDES, const void *BUFFER, size_t
+- SIZE, off64_t OFFSET)
+- This function is similar to the `pwrite' function. The difference
+- is that the OFFSET parameter is of type `off64_t' instead of
+- `off_t' which makes it possible on 32 bit machines to address
+- files larger than 2^31 bytes and up to 2^63 bytes. The file
+- descriptor `filedes' must be opened using `open64' since otherwise
+- the large offsets possible with `off64_t' will lead to errors with
+- a descriptor in small file mode.
+-
+- When the source file is compiled using `_FILE_OFFSET_BITS == 64'

+-
+-Setting the File Position of a Descriptor
+-=========================================
+-
+- Just as you can set the file position of a stream with `fseek', you
+-can set the file position of a descriptor with `lseek'. This specifies
+-the position in the file for the next `read' or `write' operation.
+-*Note File Positioning::, for more information on the file position and
+-what it means.
+-
+- To read the current file position value from a descriptor, use
+-`lseek (DESC, 0, SEEK_CUR)'.
+-
+- - Function: off_t lseek (int FILEDES, off_t OFFSET, int WHENCE)
+- The `lseek' function is used to change the file position of the
+- file with descriptor FILEDES.
+-
+- The WHENCE argument specifies how the OFFSET should be
+- interpreted, in the same way as for the `fseek' function, and it
+- must be one of the symbolic constants `SEEK_SET', `SEEK_CUR', or
+- `SEEK_END'.
+-
+- `SEEK_SET'
+- Specifies that WHENCE is a count of characters from the
+- beginning of the file.
+-
+- `SEEK_CUR'
+- Specifies that WHENCE is a count of characters from the
+- current file position. This count may be positive or
+- negative.
+-
+- `SEEK_END'
+- Specifies that WHENCE is a count of characters from the end of
+- the file. A negative count specifies a position within the
+- current extent of the file; a positive count specifies a
+- position past the current end. If you set the position past
+- the current end, and actually write data, you will extend the
+- file with zeros up to that position.
+-
+- The return value from `lseek' is normally the resulting file
+- position, measured in bytes from the beginning of the file. You
+- can use this feature together with `SEEK_CUR' to read the current
+- file position.
+-
+- If you want to append to the file, setting the file position to the
+- current end of file with `SEEK_END' is not sufficient. Another
+- process may write more data after you seek but before you write,
+- extending the file so the position you write onto clobbers their
+- data. Instead, use the `O_APPEND' operating mode; *note Operating
+- Modes::.
+-
+- You can set the file position past the current end of the file.
+- This does not by itself make the file longer; `lseek' never
+- changes the file. But subsequent output at that position will
+- extend the file. Characters between the previous end of file and
+- the new position are filled with zeros. Extending the file in
+- this way can create a "hole": the blocks of zeros are not actually
+- allocated on disk, so the file takes up less space than it appears
+- to; it is then called a "sparse file".
+-
+- If the file position cannot be changed, or the operation is in
+- some way invalid, `lseek' returns a value of -1. The following
+- `errno' error conditions are defined for this function:
+-
+- `EBADF'
+- The FILEDES is not a valid file descriptor.
+-
+- `EINVAL'
+- The WHENCE argument value is not valid, or the resulting file
+- offset is not valid. A file offset is invalid.
+-
+- `ESPIPE'
+- The FILEDES corresponds to an object that cannot be
+- positioned, such as a pipe, FIFO or terminal device.
+- (POSIX.1 specifies this error only for pipes and FIFOs, but
+- in the GNU system, you always get `ESPIPE' if the object is
+- not seekable.)
+-
+- When the source file is compiled with `_FILE_OFFSET_BITS == 64' the
+- `lseek' function is in fact `lseek64' and the type `off_t' has 64
+- bits which makes it possible to handle files up to 2^63 bytes in
+- length.
+-
+- This function is a cancellation point in multi-threaded programs.
+- This is a problem if the thread allocates some resources (like
+- memory, file descriptors, semaphores or whatever) at the time
+- `lseek' is called. If the thread gets canceled these resources
+- stay allocated until the program ends. To avoid this calls to
+- `lseek' should be protected using cancellation handlers.
+-
+- The `lseek' function is the underlying primitive for the `fseek',
+- `fseeko', `ftell', `ftello' and `rewind' functions, which operate
+- on streams instead of file descriptors.
+-
+- - Function: off64_t lseek64 (int FILEDES, off64_t OFFSET, int WHENCE)
+- This function is similar to the `lseek' function. The difference
+- is that the OFFSET parameter is of type `off64_t' instead of
+- `off_t' which makes it possible on 32 bit machines to address
+- files larger than 2^31 bytes and up to 2^63 bytes. The file
+- descriptor `filedes' must be opened using `open64' since otherwise
+- the large offsets possible with `off64_t' will lead to errors with
+- a descriptor in small file mode.
+-
+- When the source file is compiled with `_FILE_OFFSET_BITS == 64' on
+- a 32 bits machine this function is actually available under the
+- name `lseek' and so transparently replaces the 32 bit interface.
+-
+- You can have multiple descriptors for the same file if you open the
+-file more than once, or if you duplicate a descriptor with `dup'.
+-Descriptors that come from separate calls to `open' have independent
+-file positions; using `lseek' on one descriptor has no effect on the
+-other. For example,
+-
+- {
+- int d1, d2;
+- char buf[4];
+- d1 = open ("foo", O_RDONLY);
+- d2 = open ("foo", O_RDONLY);
+- lseek (d1, 1024, SEEK_SET);
+- read (d2, buf, 4);
+- }
+-
+-will read the first four characters of the file `foo'. (The
+-error-checking code necessary for a real program has been omitted here
+-for brevity.)
+-
+- By contrast, descriptors made by duplication share a common file
+-position with the original descriptor that was duplicated. Anything
+-which alters the file position of one of the duplicates, including
+-reading or writing data, affects all of them alike. Thus, for example,
+-
+- {
+- int d1, d2, d3;
+- char buf1[4], buf2[4];
+- d1 = open ("foo", O_RDONLY);
+- d2 = dup (d1);
+- d3 = dup (d2);
+- lseek (d3, 1024, SEEK_SET);
+- read (d1, buf1, 4);
+- read (d2, buf2, 4);
+- }
+-
+-will read four characters starting with the 1024'th character of `foo',
+-and then four more characters starting with the 1028'th character.
+-
+- - Data Type: off_t
+- This is an arithmetic data type used to represent file sizes. In
+- the GNU system, this is equivalent to `fpos_t' or `long int'.
+-
+- If the source is compiled with `_FILE_OFFSET_BITS == 64' this type
+- is transparently replaced by `off64_t'.
+-
+- - Data Type: off64_t
+- This type is used similar to `off_t'. The difference is that even
+- on 32 bit machines, where the `off_t' type would have 32 bits,

+-Descriptors and Streams
+-=======================
+-
+- Given an open file descriptor, you can create a stream for it with
+-the `fdopen' function. You can get the underlying file descriptor for
+-an existing stream with the `fileno' function. These functions are
+-declared in the header file `stdio.h'.
+-
+- - Function: FILE * fdopen (int FILEDES, const char *OPENTYPE)
+- The `fdopen' function returns a new stream for the file descriptor
+- FILEDES.
+-
+- The OPENTYPE argument is interpreted in the same way as for the
+- `fopen' function (*note Opening Streams::), except that the `b'
+- option is not permitted; this is because GNU makes no distinction
+- between text and binary files. Also, `"w"' and `"w+"' do not
+- cause truncation of the file; these have an effect only when
+- opening a file, and in this case the file has already been opened.
+- You must make sure that the OPENTYPE argument matches the actual
+- mode of the open file descriptor.
+-
+- The return value is the new stream. If the stream cannot be
+- created (for example, if the modes for the file indicated by the
+- file descriptor do not permit the access specified by the OPENTYPE
+- argument), a null pointer is returned instead.
+-
+- In some other systems, `fdopen' may fail to detect that the modes
+- for file descriptor do not permit the access specified by
+- `opentype'. The GNU C library always checks for this.
+-
+- For an example showing the use of the `fdopen' function, see *Note
+-Creating a Pipe::.
+-
+- - Function: int fileno (FILE *STREAM)
+- This function returns the file descriptor associated with the
+- stream STREAM. If an error is detected (for example, if the STREAM
+- is not valid) or if STREAM does not do I/O to a file, `fileno'
+- returns -1.
+-
+- - Function: int fileno_unlocked (FILE *STREAM)
+- The `fileno_unlocked' function is equivalent to the `fileno'
+- function except that it does not implicitly lock the stream if the
+- state is `FSETLOCKING_INTERNAL'.
+-
+- This function is a GNU extension.
+-
+- There are also symbolic constants defined in `unistd.h' for the file
+-descriptors belonging to the standard streams `stdin', `stdout', and
+-`stderr'; see *Note Standard Streams::.
+-
+-`STDIN_FILENO'
+- This macro has value `0', which is the file descriptor for
+- standard input.
+-
+-`STDOUT_FILENO'
+- This macro has value `1', which is the file descriptor for
+- standard output.
+-
+-`STDERR_FILENO'
+- This macro has value `2', which is the file descriptor for
+- standard error output.

+-
+-Dangers of Mixing Streams and Descriptors
+-=========================================
+-
+- You can have multiple file descriptors and streams (let's call both
+-streams and descriptors "channels" for short) connected to the same
+-file, but you must take care to avoid confusion between channels. There
+-are two cases to consider: "linked" channels that share a single file
+-position value, and "independent" channels that have their own file
+-positions.
+-
+- It's best to use just one channel in your program for actual data
+-transfer to any given file, except when all the access is for input.
+-For example, if you open a pipe (something you can only do at the file
+-descriptor level), either do all I/O with the descriptor, or construct a
+-stream from the descriptor with `fdopen' and then do all I/O with the
+-stream.
+-
+-* Menu:
+-
+-* Linked Channels:: Dealing with channels sharing a file position.
+-* Independent Channels:: Dealing with separately opened, unlinked channels.
+-* Cleaning Streams:: Cleaning a stream makes it safe to use
+- another channel.
+-
+-\1f
+-File: libc.info, Node: Linked Channels, Next: Independent Channels, Up: Stream/Descriptor Precautions
+-
+-Linked Channels
+----------------
+-
+- Channels that come from a single opening share the same file
+-position; we call them "linked" channels. Linked channels result when
+-you make a stream from a descriptor using `fdopen', when you get a
+-descriptor from a stream with `fileno', when you copy a descriptor with
+-`dup' or `dup2', and when descriptors are inherited during `fork'. For
+-files that don't support random access, such as terminals and pipes,
+-_all_ channels are effectively linked. On random-access files, all
+-append-type output streams are effectively linked to each other.
+-
+- If you have been using a stream for I/O (or have just opened the
+-stream), and you want to do I/O using another channel (either a stream
+-or a descriptor) that is linked to it, you must first "clean up" the
+-stream that you have been using. *Note Cleaning Streams::.
+-
+- Terminating a process, or executing a new program in the process,
+-destroys all the streams in the process. If descriptors linked to these
+-streams persist in other processes, their file positions become
+-undefined as a result. To prevent this, you must clean up the streams
+-before destroying them.
+-
+-\1f
+-File: libc.info, Node: Independent Channels, Next: Cleaning Streams, Prev: Linked Channels, Up: Stream/Descriptor Precautions
+-
+-Independent Channels
+---------------------
+-
+- When you open channels (streams or descriptors) separately on a
+-seekable file, each channel has its own file position. These are called
+-"independent channels".
+-
+- The system handles each channel independently. Most of the time,
+-this is quite predictable and natural (especially for input): each
+-channel can read or write sequentially at its own place in the file.
+-However, if some of the channels are streams, you must take these
+-precautions:
+-
+- * You should clean an output stream after use, before doing anything
+- else that might read or write from the same part of the file.
+-
+- * You should clean an input stream before reading data that may have
+- been modified using an independent channel. Otherwise, you might
+- read obsolete data that had been in the stream's buffer.
+-
+- If you do output to one channel at the end of the file, this will
+-certainly leave the other independent channels positioned somewhere
+-before the new end. You cannot reliably set their file positions to the
+-new end of file before writing, because the file can always be extended
+-by another process between when you set the file position and when you
+-write the data. Instead, use an append-type descriptor or stream; they
+-always output at the current end of the file. In order to make the
+-end-of-file position accurate, you must clean the output channel you
+-were using, if it is a stream.
+-
+- It's impossible for two channels to have separate file pointers for a
+-file that doesn't support random access. Thus, channels for reading or
+-writing such files are always linked, never independent. Append-type
+-channels are also always linked. For these channels, follow the rules
+-for linked channels; see *Note Linked Channels::.
+-
+-\1f
+-File: libc.info, Node: Cleaning Streams, Prev: Independent Channels, Up: Stream/Descriptor Precautions
+-
+-Cleaning Streams
+-----------------
+-
+- On the GNU system, you can clean up any stream with `fclean':
+-
+- - Function: int fclean (FILE *STREAM)
+- Clean up the stream STREAM so that its buffer is empty. If STREAM
+- is doing output, force it out. If STREAM is doing input, give the
+- data in the buffer back to the system, arranging to reread it.
+-
+- On other systems, you can use `fflush' to clean a stream in most
+-cases.
+-
+- You can skip the `fclean' or `fflush' if you know the stream is
+-already clean. A stream is clean whenever its buffer is empty. For
+-example, an unbuffered stream is always clean. An input stream that is
+-at end-of-file is clean. A line-buffered stream is clean when the last
+-character output was a newline. However, a just-opened input stream
+-might not be clean, as its input buffer might not be empty.
+-
+- There is one case in which cleaning a stream is impossible on most
+-systems. This is when the stream is doing input from a file that is not
+-random-access. Such streams typically read ahead, and when the file is
+-not random access, there is no way to give back the excess data already
+-read. When an input stream reads from a random-access file, `fflush'
+-does clean the stream, but leaves the file pointer at an unpredictable
+-place; you must set the file pointer before doing any further I/O. On
+-the GNU system, using `fclean' avoids both of these problems.
+-
+- Closing an output-only stream also does `fflush', so this is a valid
+-way of cleaning an output stream. On the GNU system, closing an input
+-stream does `fclean'.
+-
+- You need not clean a stream before using its descriptor for control
+-operations such as setting terminal modes; these operations don't affect
+-the file position and are not affected by it. You can use any
+-descriptor for these operations, and all channels are affected
+-simultaneously. However, text already "output" to a stream but still
+-buffered by the stream will be subject to the new terminal modes when
+-subsequently flushed. To make sure "past" output is covered by the
+-terminal settings that were in effect at the time, flush the output
+-streams for that terminal before setting the modes. *Note Terminal
+-Modes::.

+-
+-Fast Scatter-Gather I/O
+-=======================
+-
+- Some applications may need to read or write data to multiple buffers,
+-which are separated in memory. Although this can be done easily enough
+-with multiple calls to `read' and `write', it is inefficient because
+-there is overhead associated with each kernel call.
+-
+- Instead, many platforms provide special high-speed primitives to
+-perform these "scatter-gather" operations in a single kernel call. The
+-GNU C library will provide an emulation on any system that lacks these
+-primitives, so they are not a portability threat. They are defined in
+-`sys/uio.h'.
+-
+- These functions are controlled with arrays of `iovec' structures,
+-which describe the location and size of each buffer.
+-
+- - Data Type: struct iovec
+- The `iovec' structure describes a buffer. It contains two fields:
+-
+- `void *iov_base'
+- Contains the address of a buffer.
+-
+- `size_t iov_len'
+- Contains the length of the buffer.
+-
+-
+- - Function: ssize_t readv (int FILEDES, const struct iovec *VECTOR,
+- int COUNT)
+- The `readv' function reads data from FILEDES and scatters it into
+- the buffers described in VECTOR, which is taken to be COUNT
+- structures long. As each buffer is filled, data is sent to the
+- next.
+-
+- Note that `readv' is not guaranteed to fill all the buffers. It
+- may stop at any point, for the same reasons `read' would.
+-
+- The return value is a count of bytes (_not_ buffers) read, 0
+- indicating end-of-file, or -1 indicating an error. The possible
+- errors are the same as in `read'.
+-
+-
+- - Function: ssize_t writev (int FILEDES, const struct iovec *VECTOR,
+- int COUNT)
+- The `writev' function gathers data from the buffers described in
+- VECTOR, which is taken to be COUNT structures long, and writes
+- them to `filedes'. As each buffer is written, it moves on to the
+- next.
+-
+- Like `readv', `writev' may stop midstream under the same
+- conditions `write' would.
+-
+- The return value is a count of bytes written, or -1 indicating an
+- error. The possible errors are the same as in `write'.
+-
+-
+- Note that if the buffers are small (under about 1kB), high-level
+-streams may be easier to use than these functions. However, `readv' and
+-`writev' are more efficient when the individual buffers themselves (as
+-opposed to the total output), are large. In that case, a high-level
+-stream would not be able to cache the data effectively.

+-
+-Memory-mapped I/O
+-=================
+-
+- On modern operating systems, it is possible to "mmap" (pronounced
+-"em-map") a file to a region of memory. When this is done, the file can
+-be accessed just like an array in the program.
+-
+- This is more efficient than `read' or `write', as only the regions
+-of the file that a program actually accesses are loaded. Accesses to
+-not-yet-loaded parts of the mmapped region are handled in the same way
+-as swapped out pages.
+-
+- Since mmapped pages can be stored back to their file when physical
+-memory is low, it is possible to mmap files orders of magnitude larger
+-than both the physical memory _and_ swap space. The only limit is
+-address space. The theoretical limit is 4GB on a 32-bit machine -
+-however, the actual limit will be smaller since some areas will be
+-reserved for other purposes. If the LFS interface is used the file size
+-on 32-bit systems is not limited to 2GB (offsets are signed which
+-reduces the addressable area of 4GB by half); the full 64-bit are
+-available.
+-
+- Memory mapping only works on entire pages of memory. Thus, addresses
+-for mapping must be page-aligned, and length values will be rounded up.
+-To determine the size of a page the machine uses one should use
+-
+- size_t page_size = (size_t) sysconf (_SC_PAGESIZE);
+-
+-These functions are declared in `sys/mman.h'.
+-
+- - Function: void * mmap (void *ADDRESS, size_t LENGTH,int PROTECT, int
+- FLAGS, int FILEDES, off_t OFFSET)
+- The `mmap' function creates a new mapping, connected to bytes
+- (OFFSET) to (OFFSET + LENGTH - 1) in the file open on FILEDES. A
+- new reference for the file specified by FILEDES is created, which
+- is not removed by closing the file.
+-
+- ADDRESS gives a preferred starting address for the mapping.
+- `NULL' expresses no preference. Any previous mapping at that
+- address is automatically removed. The address you give may still be
+- changed, unless you use the `MAP_FIXED' flag.
+-
+- PROTECT contains flags that control what kind of access is
+- permitted. They include `PROT_READ', `PROT_WRITE', and
+- `PROT_EXEC', which permit reading, writing, and execution,
+- respectively. Inappropriate access will cause a segfault (*note
+- Program Error Signals::).
+-
+- Note that most hardware designs cannot support write permission
+- without read permission, and many do not distinguish read and
+- execute permission. Thus, you may receive wider permissions than
+- you ask for, and mappings of write-only files may be denied even
+- if you do not use `PROT_READ'.
+-
+- FLAGS contains flags that control the nature of the map. One of
+- `MAP_SHARED' or `MAP_PRIVATE' must be specified.
+-
+- They include:
+-
+- `MAP_PRIVATE'
+- This specifies that writes to the region should never be
+- written back to the attached file. Instead, a copy is made
+- for the process, and the region will be swapped normally if
+- memory runs low. No other process will see the changes.
+-
+- Since private mappings effectively revert to ordinary memory
+- when written to, you must have enough virtual memory for a
+- copy of the entire mmapped region if you use this mode with
+- `PROT_WRITE'.
+-
+- `MAP_SHARED'
+- This specifies that writes to the region will be written back
+- to the file. Changes made will be shared immediately with
+- other processes mmaping the same file.
+-
+- Note that actual writing may take place at any time. You
+- need to use `msync', described below, if it is important that
+- other processes using conventional I/O get a consistent view
+- of the file.
+-
+- `MAP_FIXED'
+- This forces the system to use the exact mapping address
+- specified in ADDRESS and fail if it can't.
+-
+- `MAP_ANONYMOUS'
+- `MAP_ANON'
+- This flag tells the system to create an anonymous mapping,
+- not connected to a file. FILEDES and OFF are ignored, and
+- the region is initialized with zeros.
+-
+- Anonymous maps are used as the basic primitive to extend the
+- heap on some systems. They are also useful to share data
+- between multiple tasks without creating a file.
+-
+- On some systems using private anonymous mmaps is more
+- efficient than using `malloc' for large blocks. This is not
+- an issue with the GNU C library, as the included `malloc'
+- automatically uses `mmap' where appropriate.
+-
+- `mmap' returns the address of the new mapping, or -1 for an error.
+-
+- Possible errors include:
+-
+- `EINVAL'
+- Either ADDRESS was unusable, or inconsistent FLAGS were given.
+-
+- `EACCES'
+- FILEDES was not open for the type of access specified in
+- PROTECT.
+-
+- `ENOMEM'
+- Either there is not enough memory for the operation, or the
+- process is out of address space.
+-
+- `ENODEV'
+- This file is of a type that doesn't support mapping.
+-
+- `ENOEXEC'
+- The file is on a filesystem that doesn't support mapping.
+-
+-
+- - Function: void * mmap64 (void *ADDRESS, size_t LENGTH,int PROTECT,
+- int FLAGS, int FILEDES, off64_t OFFSET)
+- The `mmap64' function is equivalent to the `mmap' function but the
+- OFFSET parameter is of type `off64_t'. On 32-bit systems this
+- allows the file associated with the FILEDES descriptor to be
+- larger than 2GB. FILEDES must be a descriptor returned from a
+- call to `open64' or `fopen64' and `freopen64' where the descriptor
+- is retrieved with `fileno'.
+-
+- When the sources are translated with `_FILE_OFFSET_BITS == 64' this
+- function is actually available under the name `mmap'. I.e., the
+- new, extended API using 64 bit file sizes and offsets transparently
+- replaces the old API.
+-
+- - Function: int munmap (void *ADDR, size_t LENGTH)
+- `munmap' removes any memory maps from (ADDR) to (ADDR + LENGTH).
+- LENGTH should be the length of the mapping.
+-
+- It is safe to unmap multiple mappings in one command, or include
+- unmapped space in the range. It is also possible to unmap only
+- part of an existing mapping. However, only entire pages can be
+- removed. If LENGTH is not an even number of pages, it will be
+- rounded up.
+-
+- It returns 0 for success and -1 for an error.
+-
+- One error is possible:
+-
+- `EINVAL'
+- The memory range given was outside the user mmap range or
+- wasn't page aligned.
+-
+-
+- - Function: int msync (void *ADDRESS, size_t LENGTH, int FLAGS)
+- When using shared mappings, the kernel can write the file at any
+- time before the mapping is removed. To be certain data has
+- actually been written to the file and will be accessible to
+- non-memory-mapped I/O, it is necessary to use this function.
+-
+- It operates on the region ADDRESS to (ADDRESS + LENGTH). It may
+- be used on part of a mapping or multiple mappings, however the
+- region given should not contain any unmapped space.
+-
+- FLAGS can contain some options:
+-
+- `MS_SYNC'
+- This flag makes sure the data is actually written _to disk_.
+- Normally `msync' only makes sure that accesses to a file with
+- conventional I/O reflect the recent changes.
+-
+- `MS_ASYNC'
+- This tells `msync' to begin the synchronization, but not to
+- wait for it to complete.
+-
+- `msync' returns 0 for success and -1 for error. Errors include:
+-
+- `EINVAL'
+- An invalid region was given, or the FLAGS were invalid.
+-
+- `EFAULT'
+- There is no existing mapping in at least part of the given
+- region.
+-
+-
+- - Function: void * mremap (void *ADDRESS, size_t LENGTH, size_t
+- NEW_LENGTH, int FLAG)
+- This function can be used to change the size of an existing memory
+- area. ADDRESS and LENGTH must cover a region entirely mapped in
+- the same `mmap' statement. A new mapping with the same
+- characteristics will be returned with the length NEW_LENGTH.
+-
+- One option is possible, `MREMAP_MAYMOVE'. If it is given in FLAGS,
+- the system may remove the existing mapping and create a new one of
+- the desired length in another location.
+-
+- The address of the resulting mapping is returned, or -1. Possible
+- error codes include:
+-
+- `EFAULT'
+- There is no existing mapping in at least part of the original
+- region, or the region covers two or more distinct mappings.
+-
+- `EINVAL'
+- The address given is misaligned or inappropriate.
+-
+- `EAGAIN'
+- The region has pages locked, and if extended it would exceed
+- the process's resource limit for locked pages. *Note Limits
+- on Resources::.
+-
+- `ENOMEM'
+- The region is private writable, and insufficient virtual
+- memory is available to extend it. Also, this error will
+- occur if `MREMAP_MAYMOVE' is not given and the extension
+- would collide with another mapped region.
+-
+-
+- This function is only available on a few systems. Except for
+-performing optional optimizations one should not rely on this function.
+-
+- Not all file descriptors may be mapped. Sockets, pipes, and most
+-devices only allow sequential access and do not fit into the mapping
+-abstraction. In addition, some regular files may not be mmapable, and
+-older kernels may not support mapping at all. Thus, programs using
+-`mmap' should have a fallback method to use should it fail. *Note Mmap:
+-(standards)Mmap.
+-
+- - Function: int madvise (void *ADDR, size_t LENGTH, int ADVICE)
+- This function can be used to provide the system with ADVICE about
+- the intended usage patterns of the memory region starting at ADDR
+- and extending LENGTH bytes.
+-
+- The valid BSD values for ADVICE are:
+-
+- `MADV_NORMAL'
+- The region should receive no further special treatment.
+-
+- `MADV_RANDOM'
+- The region will be accessed via random page references. The
+- kernel should page-in the minimal number of pages for each
+- page fault.
+-
+- `MADV_SEQUENTIAL'
+- The region will be accessed via sequential page references.
+- This may cause the kernel to aggressively read-ahead,
+- expecting further sequential references after any page fault
+- within this region.
+-
+- `MADV_WILLNEED'
+- The region will be needed. The pages within this region may
+- be pre-faulted in by the kernel.
+-
+- `MADV_DONTNEED'
+- The region is no longer needed. The kernel may free these
+- pages, causing any changes to the pages to be lost, as well
+- as swapped out pages to be discarded.
+-
+- The POSIX names are slightly different, but with the same meanings:
+-
+- `POSIX_MADV_NORMAL'
+- This corresponds with BSD's `MADV_NORMAL'.
+-
+- `POSIX_MADV_RANDOM'
+- This corresponds with BSD's `MADV_RANDOM'.
+-
+- `POSIX_MADV_SEQUENTIAL'
+- This corresponds with BSD's `MADV_SEQUENTIAL'.
+-
+- `POSIX_MADV_WILLNEED'
+- This corresponds with BSD's `MADV_WILLNEED'.
+-
+- `POSIX_MADV_DONTNEED'
+- This corresponds with BSD's `MADV_DONTNEED'.
+-
+- `msync' returns 0 for success and -1 for error. Errors include:
+- `EINVAL'
+- An invalid region was given, or the ADVICE was invalid.
+-
+- `EFAULT'
+- There is no existing mapping in at least part of the given
+- region.

+-
+-Waiting for Input or Output
+-===========================
+-
+- Sometimes a program needs to accept input on multiple input channels
+-whenever input arrives. For example, some workstations may have devices
+-such as a digitizing tablet, function button box, or dial box that are
+-connected via normal asynchronous serial interfaces; good user interface
+-style requires responding immediately to input on any device. Another
+-example is a program that acts as a server to several other processes
+-via pipes or sockets.
+-
+- You cannot normally use `read' for this purpose, because this blocks
+-the program until input is available on one particular file descriptor;
+-input on other channels won't wake it up. You could set nonblocking
+-mode and poll each file descriptor in turn, but this is very
+-inefficient.
+-
+- A better solution is to use the `select' function. This blocks the
+-program until input or output is ready on a specified set of file
+-descriptors, or until a timer expires, whichever comes first. This
+-facility is declared in the header file `sys/types.h'.
+-
+- In the case of a server socket (*note Listening::), we say that
+-"input" is available when there are pending connections that could be
+-accepted (*note Accepting Connections::). `accept' for server sockets
+-blocks and interacts with `select' just as `read' does for normal input.
+-
+- The file descriptor sets for the `select' function are specified as
+-`fd_set' objects. Here is the description of the data type and some
+-macros for manipulating these objects.
+-
+- - Data Type: fd_set
+- The `fd_set' data type represents file descriptor sets for the
+- `select' function. It is actually a bit array.
+-
+- - Macro: int FD_SETSIZE
+- The value of this macro is the maximum number of file descriptors
+- that a `fd_set' object can hold information about. On systems
+- with a fixed maximum number, `FD_SETSIZE' is at least that number.
+- On some systems, including GNU, there is no absolute limit on the
+- number of descriptors open, but this macro still has a constant
+- value which controls the number of bits in an `fd_set'; if you get
+- a file descriptor with a value as high as `FD_SETSIZE', you cannot
+- put that descriptor into an `fd_set'.
+-
+- - Macro: void FD_ZERO (fd_set *SET)
+- This macro initializes the file descriptor set SET to be the empty
+- set.
+-
+- - Macro: void FD_SET (int FILEDES, fd_set *SET)
+- This macro adds FILEDES to the file descriptor set SET.
+-
+- - Macro: void FD_CLR (int FILEDES, fd_set *SET)
+- This macro removes FILEDES from the file descriptor set SET.
+-
+- - Macro: int FD_ISSET (int FILEDES, fd_set *SET)
+- This macro returns a nonzero value (true) if FILEDES is a member
+- of the file descriptor set SET, and zero (false) otherwise.
+-
+- Next, here is the description of the `select' function itself.
+-
+- - Function: int select (int NFDS, fd_set *READ-FDS, fd_set *WRITE-FDS,
+- fd_set *EXCEPT-FDS, struct timeval *TIMEOUT)
+- The `select' function blocks the calling process until there is
+- activity on any of the specified sets of file descriptors, or
+- until the timeout period has expired.
+-
+- The file descriptors specified by the READ-FDS argument are
+- checked to see if they are ready for reading; the WRITE-FDS file
+- descriptors are checked to see if they are ready for writing; and
+- the EXCEPT-FDS file descriptors are checked for exceptional
+- conditions. You can pass a null pointer for any of these
+- arguments if you are not interested in checking for that kind of
+- condition.
+-
+- A file descriptor is considered ready for reading if it is not at
+- end of file. A server socket is considered ready for reading if
+- there is a pending connection which can be accepted with `accept';
+- *note Accepting Connections::. A client socket is ready for
+- writing when its connection is fully established; *note
+- Connecting::.
+-
+- "Exceptional conditions" does not mean errors--errors are reported
+- immediately when an erroneous system call is executed, and do not
+- constitute a state of the descriptor. Rather, they include
+- conditions such as the presence of an urgent message on a socket.
+- (*Note Sockets::, for information on urgent messages.)
+-
+- The `select' function checks only the first NFDS file descriptors.
+- The usual thing is to pass `FD_SETSIZE' as the value of this
+- argument.
+-
+- The TIMEOUT specifies the maximum time to wait. If you pass a
+- null pointer for this argument, it means to block indefinitely
+- until one of the file descriptors is ready. Otherwise, you should
+- provide the time in `struct timeval' format; see *Note
+- High-Resolution Calendar::. Specify zero as the time (a `struct
+- timeval' containing all zeros) if you want to find out which
+- descriptors are ready without waiting if none are ready.
+-
+- The normal return value from `select' is the total number of ready
+- file descriptors in all of the sets. Each of the argument sets is
+- overwritten with information about the descriptors that are ready
+- for the corresponding operation. Thus, to see if a particular
+- descriptor DESC has input, use `FD_ISSET (DESC, READ-FDS)' after
+- `select' returns.
+-
+- If `select' returns because the timeout period expires, it returns
+- a value of zero.
+-
+- Any signal will cause `select' to return immediately. So if your
+- program uses signals, you can't rely on `select' to keep waiting
+- for the full time specified. If you want to be sure of waiting
+- for a particular amount of time, you must check for `EINTR' and
+- repeat the `select' with a newly calculated timeout based on the
+- current time. See the example below. See also *Note Interrupted
+- Primitives::.
+-
+- If an error occurs, `select' returns `-1' and does not modify the
+- argument file descriptor sets. The following `errno' error
+- conditions are defined for this function:
+-
+- `EBADF'
+- One of the file descriptor sets specified an invalid file
+- descriptor.
+-
+- `EINTR'
+- The operation was interrupted by a signal. *Note Interrupted
+- Primitives::.
+-
+- `EINVAL'
+- The TIMEOUT argument is invalid; one of the components is
+- negative or too large.
+-
+- *Portability Note:* The `select' function is a BSD Unix feature.
+-
+- Here is an example showing how you can use `select' to establish a
+-timeout period for reading from a file descriptor. The `input_timeout'
+-function blocks the calling process until input is available on the
+-file descriptor, or until the timeout period expires.
+-
+- #include <errno.h>
+- #include <stdio.h>
+- #include <unistd.h>
+- #include <sys/types.h>
+- #include <sys/time.h>
+-
+- int
+- input_timeout (int filedes, unsigned int seconds)
+- {
+- fd_set set;
+- struct timeval timeout;
+-
+- /* Initialize the file descriptor set. */
+- FD_ZERO (&set);
+- FD_SET (filedes, &set);
+-
+- /* Initialize the timeout data structure. */
+- timeout.tv_sec = seconds;
+- timeout.tv_usec = 0;
+-
+- /* `select' returns 0 if timeout, 1 if input available, -1 if error. */
+- return TEMP_FAILURE_RETRY (select (FD_SETSIZE,
+- &set, NULL, NULL,
+- &timeout));
+- }
+-
+- int
+- main (void)
+- {
+- fprintf (stderr, "select returned %d.\n",
+- input_timeout (STDIN_FILENO, 5));
+- return 0;
+- }

+-input from multiple sockets in *Note Server Example::.

+-Synchronizing I/O operations
+-============================
+-
+- In most modern operating systems, the normal I/O operations are not
+-executed synchronously. I.e., even if a `write' system call returns,
+-this does not mean the data is actually written to the media, e.g., the
+-disk.
+-
+- In situations where synchronization points are necessary, you can use
+-special functions which ensure that all operations finish before they
+-return.
+-
+- - Function: int sync (void)
+- A call to this function will not return as long as there is data
+- which has not been written to the device. All dirty buffers in
+- the kernel will be written and so an overall consistent system can
+- be achieved (if no other process in parallel writes data).
+-
+- A prototype for `sync' can be found in `unistd.h'.
+-
+- The return value is zero to indicate no error.
+-
+- Programs more often want to ensure that data written to a given file
+-is committed, rather than all data in the system. For this, `sync' is
+-overkill.
+-
+- - Function: int fsync (int FILDES)
+- The `fsync' function can be used to make sure all data associated
+- with the open file FILDES is written to the device associated with
+- the descriptor. The function call does not return unless all
+- actions have finished.
+-
+- A prototype for `fsync' can be found in `unistd.h'.
+-
+- This function is a cancellation point in multi-threaded programs.
+- This is a problem if the thread allocates some resources (like
+- memory, file descriptors, semaphores or whatever) at the time
+- `fsync' is called. If the thread gets canceled these resources
+- stay allocated until the program ends. To avoid this, calls to
+- `fsync' should be protected using cancellation handlers.
+-
+- The return value of the function is zero if no error occurred.
+- Otherwise it is -1 and the global variable ERRNO is set to the
+- following values:
+- `EBADF'
+- The descriptor FILDES is not valid.
+-
+- `EINVAL'
+- No synchronization is possible since the system does not
+- implement this.
+-
+- Sometimes it is not even necessary to write all data associated with
+-a file descriptor. E.g., in database files which do not change in size
+-it is enough to write all the file content data to the device.
+-Meta-information, like the modification time etc., are not that
+-important and leaving such information uncommitted does not prevent a
+-successful recovering of the file in case of a problem.
+-
+- - Function: int fdatasync (int FILDES)
+- When a call to the `fdatasync' function returns, it is ensured
+- that all of the file data is written to the device. For all
+- pending I/O operations, the parts guaranteeing data integrity
+- finished.
+-
+- Not all systems implement the `fdatasync' operation. On systems
+- missing this functionality `fdatasync' is emulated by a call to
+- `fsync' since the performed actions are a superset of those
+- required by `fdatasync'.
+-
+- The prototype for `fdatasync' is in `unistd.h'.
+-
+- The return value of the function is zero if no error occurred.
+- Otherwise it is -1 and the global variable ERRNO is set to the
+- following values:
+- `EBADF'
+- The descriptor FILDES is not valid.
+-
+- `EINVAL'
+- No synchronization is possible since the system does not
+- implement this.

+-
+-Perform I/O Operations in Parallel
+-==================================
+-
+- The POSIX.1b standard defines a new set of I/O operations which can
+-significantly reduce the time an application spends waiting at I/O. The
+-new functions allow a program to initiate one or more I/O operations and
+-then immediately resume normal work while the I/O operations are
+-executed in parallel. This functionality is available if the
+-`unistd.h' file defines the symbol `_POSIX_ASYNCHRONOUS_IO'.
+-
+- These functions are part of the library with realtime functions named
+-`librt'. They are not actually part of the `libc' binary. The
+-implementation of these functions can be done using support in the
+-kernel (if available) or using an implementation based on threads at
+-userlevel. In the latter case it might be necessary to link
+-applications with the thread library `libpthread' in addition to
+-`librt'.
+-
+- All AIO operations operate on files which were opened previously.
+-There might be arbitrarily many operations running for one file. The
+-asynchronous I/O operations are controlled using a data structure named
+-`struct aiocb' ("AIO control block"). It is defined in `aio.h' as
+-follows.
+-
+- - Data Type: struct aiocb
+- The POSIX.1b standard mandates that the `struct aiocb' structure
+- contains at least the members described in the following table.
+- There might be more elements which are used by the implementation,
+- but depending upon these elements is not portable and is highly
+- deprecated.
+-
+- `int aio_fildes'
+- This element specifies the file descriptor to be used for the
+- operation. It must be a legal descriptor, otherwise the
+- operation will fail.
+-
+- The device on which the file is opened must allow the seek
+- operation. I.e., it is not possible to use any of the AIO
+- operations on devices like terminals where an `lseek' call
+- would lead to an error.
+-
+- `off_t aio_offset'
+- This element specifies the offset in the file at which the
+- operation (input or output) is performed. Since the
+- operations are carried out in arbitrary order and more than
+- one operation for one file descriptor can be started, one
+- cannot expect a current read/write position of the file
+- descriptor.
+-
+- `volatile void *aio_buf'
+- This is a pointer to the buffer with the data to be written
+- or the place where the read data is stored.
+-
+- `size_t aio_nbytes'
+- This element specifies the length of the buffer pointed to by
+- `aio_buf'.
+-
+- `int aio_reqprio'
+- If the platform has defined `_POSIX_PRIORITIZED_IO' and
+- `_POSIX_PRIORITY_SCHEDULING', the AIO requests are processed
+- based on the current scheduling priority. The `aio_reqprio'
+- element can then be used to lower the priority of the AIO
+- operation.
+-
+- `struct sigevent aio_sigevent'
+- This element specifies how the calling process is notified
+- once the operation terminates. If the `sigev_notify' element
+- is `SIGEV_NONE', no notification is sent. If it is
+- `SIGEV_SIGNAL', the signal determined by `sigev_signo' is
+- sent. Otherwise, `sigev_notify' must be `SIGEV_THREAD'. In
+- this case, a thread is created which starts executing the
+- function pointed to by `sigev_notify_function'.
+-
+- `int aio_lio_opcode'
+- This element is only used by the `lio_listio' and
+- `lio_listio64' functions. Since these functions allow an
+- arbitrary number of operations to start at once, and each
+- operation can be input or output (or nothing), the
+- information must be stored in the control block. The
+- possible values are:
+-
+- `LIO_READ'
+- Start a read operation. Read from the file at position
+- `aio_offset' and store the next `aio_nbytes' bytes in the
+- buffer pointed to by `aio_buf'.
+-
+- `LIO_WRITE'
+- Start a write operation. Write `aio_nbytes' bytes
+- starting at `aio_buf' into the file starting at position
+- `aio_offset'.
+-
+- `LIO_NOP'
+- Do nothing for this control block. This value is useful
+- sometimes when an array of `struct aiocb' values
+- contains holes, i.e., some of the values must not be
+- handled although the whole array is presented to the
+- `lio_listio' function.
+-
+- When the sources are compiled using `_FILE_OFFSET_BITS == 64' on a
+- 32 bit machine, this type is in fact `struct aiocb64', since the
+- LFS interface transparently replaces the `struct aiocb' definition.
+-
+- For use with the AIO functions defined in the LFS, there is a
+-similar type defined which replaces the types of the appropriate
+-members with larger types but otherwise is equivalent to `struct
+-aiocb'. Particularly, all member names are the same.
+-
+- - Data Type: struct aiocb64
+- `int aio_fildes'
+- This element specifies the file descriptor which is used for
+- the operation. It must be a legal descriptor since otherwise
+- the operation fails for obvious reasons.
+-
+- The device on which the file is opened must allow the seek
+- operation. I.e., it is not possible to use any of the AIO
+- operations on devices like terminals where an `lseek' call
+- would lead to an error.
+-
+- `off64_t aio_offset'
+- This element specifies at which offset in the file the
+- operation (input or output) is performed. Since the
+- operation are carried in arbitrary order and more than one
+- operation for one file descriptor can be started, one cannot
+- expect a current read/write position of the file descriptor.
+-
+- `volatile void *aio_buf'
+- This is a pointer to the buffer with the data to be written
+- or the place where the read data is stored.
+-
+- `size_t aio_nbytes'
+- This element specifies the length of the buffer pointed to by
+- `aio_buf'.
+-
+- `int aio_reqprio'
+- If for the platform `_POSIX_PRIORITIZED_IO' and
+- `_POSIX_PRIORITY_SCHEDULING' are defined the AIO requests are
+- processed based on the current scheduling priority. The
+- `aio_reqprio' element can then be used to lower the priority
+- of the AIO operation.
+-
+- `struct sigevent aio_sigevent'
+- This element specifies how the calling process is notified
+- once the operation terminates. If the `sigev_notify',
+- element is `SIGEV_NONE' no notification is sent. If it is
+- `SIGEV_SIGNAL', the signal determined by `sigev_signo' is
+- sent. Otherwise, `sigev_notify' must be `SIGEV_THREAD' in
+- which case a thread which starts executing the function
+- pointed to by `sigev_notify_function'.
+-
+- `int aio_lio_opcode'
+- This element is only used by the `lio_listio' and
+- `[lio_listio64' functions. Since these functions allow an
+- arbitrary number of operations to start at once, and since
+- each operation can be input or output (or nothing), the
+- information must be stored in the control block. See the
+- description of `struct aiocb' for a description of the
+- possible values.
+-
+- When the sources are compiled using `_FILE_OFFSET_BITS == 64' on a
+- 32 bit machine, this type is available under the name `struct
+- aiocb64', since the LFS transparently replaces the old interface.

+-Asynchronous Read and Write Operations
+---------------------------------------
+-
+- - Function: int aio_read (struct aiocb *AIOCBP)
+- This function initiates an asynchronous read operation. It
+- immediately returns after the operation was enqueued or when an
+- error was encountered.
+-
+- The first `aiocbp->aio_nbytes' bytes of the file for which
+- `aiocbp->aio_fildes' is a descriptor are written to the buffer
+- starting at `aiocbp->aio_buf'. Reading starts at the absolute
+- position `aiocbp->aio_offset' in the file.
+-
+- If prioritized I/O is supported by the platform the
+- `aiocbp->aio_reqprio' value is used to adjust the priority before
+- the request is actually enqueued.
+-
+- The calling process is notified about the termination of the read
+- request according to the `aiocbp->aio_sigevent' value.
+-
+- When `aio_read' returns, the return value is zero if no error
+- occurred that can be found before the process is enqueued. If
+- such an early error is found, the function returns -1 and sets
+- `errno' to one of the following values:
+-
+- `EAGAIN'
+- The request was not enqueued due to (temporarily) exceeded
+- resource limitations.
+-
+- `ENOSYS'
+- The `aio_read' function is not implemented.
+-
+- `EBADF'
+- The `aiocbp->aio_fildes' descriptor is not valid. This
+- condition need not be recognized before enqueueing the
+- request and so this error might also be signaled
+- asynchronously.
+-
+- `EINVAL'
+- The `aiocbp->aio_offset' or `aiocbp->aio_reqpiro' value is
+- invalid. This condition need not be recognized before
+- enqueueing the request and so this error might also be
+- signaled asynchronously.
+-
+- If `aio_read' returns zero, the current status of the request can
+- be queried using `aio_error' and `aio_return' functions. As long
+- as the value returned by `aio_error' is `EINPROGRESS' the
+- operation has not yet completed. If `aio_error' returns zero, the
+- operation successfully terminated, otherwise the value is to be
+- interpreted as an error code. If the function terminated, the
+- result of the operation can be obtained using a call to
+- `aio_return'. The returned value is the same as an equivalent
+- call to `read' would have returned. Possible error codes returned
+- by `aio_error' are:
+-
+- `EBADF'
+- The `aiocbp->aio_fildes' descriptor is not valid.
+-
+- `ECANCELED'
+- The operation was canceled before the operation was finished
+- (*note Cancel AIO Operations::)
+-
+- `EINVAL'
+- The `aiocbp->aio_offset' value is invalid.
+-
+- When the sources are compiled with `_FILE_OFFSET_BITS == 64' this
+- function is in fact `aio_read64' since the LFS interface
+- transparently replaces the normal implementation.
+-
+- - Function: int aio_read64 (struct aiocb *AIOCBP)
+- This function is similar to the `aio_read' function. The only
+- difference is that on 32 bit machines, the file descriptor should
+- be opened in the large file mode. Internally, `aio_read64' uses
+- functionality equivalent to `lseek64' (*note File Position
+- Primitive::) to position the file descriptor correctly for the
+- reading, as opposed to `lseek' functionality used in `aio_read'.
+-
+- When the sources are compiled with `_FILE_OFFSET_BITS == 64', this
+- function is available under the name `aio_read' and so
+- transparently replaces the interface for small files on 32 bit
+- machines.
+-
+- To write data asynchronously to a file, there exists an equivalent
+-pair of functions with a very similar interface.
+-
+- - Function: int aio_write (struct aiocb *AIOCBP)
+- This function initiates an asynchronous write operation. The
+- function call immediately returns after the operation was enqueued
+- or if before this happens an error was encountered.
+-
+- The first `aiocbp->aio_nbytes' bytes from the buffer starting at
+- `aiocbp->aio_buf' are written to the file for which
+- `aiocbp->aio_fildes' is an descriptor, starting at the absolute
+- position `aiocbp->aio_offset' in the file.
+-
+- If prioritized I/O is supported by the platform, the
+- `aiocbp->aio_reqprio' value is used to adjust the priority before
+- the request is actually enqueued.
+-
+- The calling process is notified about the termination of the read
+- request according to the `aiocbp->aio_sigevent' value.
+-
+- When `aio_write' returns, the return value is zero if no error
+- occurred that can be found before the process is enqueued. If
+- such an early error is found the function returns -1 and sets
+- `errno' to one of the following values.
+-
+- `EAGAIN'
+- The request was not enqueued due to (temporarily) exceeded
+- resource limitations.
+-
+- `ENOSYS'
+- The `aio_write' function is not implemented.
+-
+- `EBADF'
+- The `aiocbp->aio_fildes' descriptor is not valid. This
+- condition may not be recognized before enqueueing the
+- request, and so this error might also be signaled
+- asynchronously.
+-
+- `EINVAL'
+- The `aiocbp->aio_offset' or `aiocbp->aio_reqprio' value is
+- invalid. This condition may not be recognized before
+- enqueueing the request and so this error might also be
+- signaled asynchronously.
+-
+- In the case `aio_write' returns zero, the current status of the
+- request can be queried using `aio_error' and `aio_return'
+- functions. As long as the value returned by `aio_error' is
+- `EINPROGRESS' the operation has not yet completed. If `aio_error'
+- returns zero, the operation successfully terminated, otherwise the
+- value is to be interpreted as an error code. If the function
+- terminated, the result of the operation can be get using a call to
+- `aio_return'. The returned value is the same as an equivalent
+- call to `read' would have returned. Possible error codes returned
+- by `aio_error' are:
+-
+- `EBADF'
+- The `aiocbp->aio_fildes' descriptor is not valid.
+-
+- `ECANCELED'
+- The operation was canceled before the operation was finished.
+- (*note Cancel AIO Operations::)
+-
+- `EINVAL'
+- The `aiocbp->aio_offset' value is invalid.
+-
+- When the sources are compiled with `_FILE_OFFSET_BITS == 64', this
+- function is in fact `aio_write64' since the LFS interface
+- transparently replaces the normal implementation.
+-
+- - Function: int aio_write64 (struct aiocb *AIOCBP)
+- This function is similar to the `aio_write' function. The only
+- difference is that on 32 bit machines the file descriptor should
+- be opened in the large file mode. Internally `aio_write64' uses
+- functionality equivalent to `lseek64' (*note File Position
+- Primitive::) to position the file descriptor correctly for the
+- writing, as opposed to `lseek' functionality used in `aio_write'.
+-
+- When the sources are compiled with `_FILE_OFFSET_BITS == 64', this
+- function is available under the name `aio_write' and so
+- transparently replaces the interface for small files on 32 bit
+- machines.
+-
+- Besides these functions with the more or less traditional interface,
+-POSIX.1b also defines a function which can initiate more than one
+-operation at a time, and which can handle freely mixed read and write
+-operations. It is therefore similar to a combination of `readv' and
+-`writev'.
+-
+- - Function: int lio_listio (int MODE, struct aiocb *const LIST[], int
+- NENT, struct sigevent *SIG)
+- The `lio_listio' function can be used to enqueue an arbitrary
+- number of read and write requests at one time. The requests can
+- all be meant for the same file, all for different files or every
+- solution in between.
+-
+- `lio_listio' gets the NENT requests from the array pointed to by
+- LIST. The operation to be performed is determined by the
+- `aio_lio_opcode' member in each element of LIST. If this field is
+- `LIO_READ' a read operation is enqueued, similar to a call of
+- `aio_read' for this element of the array (except that the way the
+- termination is signalled is different, as we will see below). If
+- the `aio_lio_opcode' member is `LIO_WRITE' a write operation is
+- enqueued. Otherwise the `aio_lio_opcode' must be `LIO_NOP' in
+- which case this element of LIST is simply ignored. This
+- "operation" is useful in situations where one has a fixed array of
+- `struct aiocb' elements from which only a few need to be handled at
+- a time. Another situation is where the `lio_listio' call was
+- canceled before all requests are processed (*note Cancel AIO
+- Operations::) and the remaining requests have to be reissued.
+-
+- The other members of each element of the array pointed to by
+- `list' must have values suitable for the operation as described in
+- the documentation for `aio_read' and `aio_write' above.
+-
+- The MODE argument determines how `lio_listio' behaves after having
+- enqueued all the requests. If MODE is `LIO_WAIT' it waits until
+- all requests terminated. Otherwise MODE must be `LIO_NOWAIT' and
+- in this case the function returns immediately after having
+- enqueued all the requests. In this case the caller gets a
+- notification of the termination of all requests according to the
+- SIG parameter. If SIG is `NULL' no notification is send.
+- Otherwise a signal is sent or a thread is started, just as
+- described in the description for `aio_read' or `aio_write'.
+-
+- If MODE is `LIO_WAIT', the return value of `lio_listio' is 0 when
+- all requests completed successfully. Otherwise the function
+- return -1 and `errno' is set accordingly. To find out which
+- request or requests failed one has to use the `aio_error' function
+- on all the elements of the array LIST.
+-
+- In case MODE is `LIO_NOWAIT', the function returns 0 if all
+- requests were enqueued correctly. The current state of the
+- requests can be found using `aio_error' and `aio_return' as
+- described above. If `lio_listio' returns -1 in this mode, the
+- global variable `errno' is set accordingly. If a request did not
+- yet terminate, a call to `aio_error' returns `EINPROGRESS'. If
+- the value is different, the request is finished and the error
+- value (or 0) is returned and the result of the operation can be
+- retrieved using `aio_return'.
+-
+- Possible values for `errno' are:
+-
+- `EAGAIN'
+- The resources necessary to queue all the requests are not
+- available at the moment. The error status for each element
+- of LIST must be checked to determine which request failed.
+-
+- Another reason could be that the system wide limit of AIO
+- requests is exceeded. This cannot be the case for the
+- implementation on GNU systems since no arbitrary limits exist.
+-
+- `EINVAL'
+- The MODE parameter is invalid or NENT is larger than
+- `AIO_LISTIO_MAX'.
+-
+- `EIO'
+- One or more of the request's I/O operations failed. The
+- error status of each request should be checked to determine
+- which one failed.
+-
+- `ENOSYS'
+- The `lio_listio' function is not supported.
+-
+- If the MODE parameter is `LIO_NOWAIT' and the caller cancels a
+- request, the error status for this request returned by `aio_error'
+- is `ECANCELED'.
+-
+- When the sources are compiled with `_FILE_OFFSET_BITS == 64', this
+- function is in fact `lio_listio64' since the LFS interface
+- transparently replaces the normal implementation.
+-
+- - Function: int lio_listio64 (int MODE, struct aiocb *const LIST, int
+- NENT, struct sigevent *SIG)
+- This function is similar to the `lio_listio' function. The only
+- difference is that on 32 bit machines, the file descriptor should
+- be opened in the large file mode. Internally, `lio_listio64' uses
+- functionality equivalent to `lseek64' (*note File Position

+-
+-Getting the Status of AIO Operations
+-------------------------------------
+-
+- As already described in the documentation of the functions in the
+-last section, it must be possible to get information about the status
+-of an I/O request. When the operation is performed truly
+-asynchronously (as with `aio_read' and `aio_write' and with
+-`lio_listio' when the mode is `LIO_NOWAIT'), one sometimes needs to
+-know whether a specific request already terminated and if so, what the
+-result was. The following two functions allow you to get this kind of
+-information.
+-
+- - Function: int aio_error (const struct aiocb *AIOCBP)
+- This function determines the error state of the request described

+- `EINPROGRESS'. Once the request has terminated the value
+- `aio_error' returns is either 0 if the request completed

+-
+-Getting into a Consistent State
+--------------------------------
+-
+- When dealing with asynchronous operations it is sometimes necessary
+-to get into a consistent state. This would mean for AIO that one wants
+-to know whether a certain request or a group of request were processed.
+-This could be done by waiting for the notification sent by the system
+-after the operation terminated, but this sometimes would mean wasting
+-resources (mainly computation time). Instead POSIX.1b defines two
+-functions which will help with most kinds of consistency.
+-
+- The `aio_fsync' and `aio_fsync64' functions are only available if
+-the symbol `_POSIX_SYNCHRONIZED_IO' is defined in `unistd.h'.
+-
+- - Function: int aio_fsync (int OP, struct aiocb *AIOCBP)
+- Calling this function forces all I/O operations operating queued
+- at the time of the function call operating on the file descriptor
+- `aiocbp->aio_fildes' into the synchronized I/O completion state
+- (*note Synchronizing I/O::). The `aio_fsync' function returns
+- immediately but the notification through the method described in
+- `aiocbp->aio_sigevent' will happen only after all requests for this
+- file descriptor have terminated and the file is synchronized.
+- This also means that requests for this very same file descriptor
+- which are queued after the synchronization request are not
+- affected.
+-
+- If OP is `O_DSYNC' the synchronization happens as with a call to
+- `fdatasync'. Otherwise OP should be `O_SYNC' and the
+- synchronization happens as with `fsync'.
+-
+- As long as the synchronization has not happened, a call to
+- `aio_error' with the reference to the object pointed to by AIOCBP
+- returns `EINPROGRESS'. Once the synchronization is done
+- `aio_error' return 0 if the synchronization was not successful.
+- Otherwise the value returned is the value to which the `fsync' or
+- `fdatasync' function would have set the `errno' variable. In this
+- case nothing can be assumed about the consistency for the data
+- written to this file descriptor.
+-
+- The return value of this function is 0 if the request was
+- successfully enqueued. Otherwise the return value is -1 and
+- `errno' is set to one of the following values:
+-
+- `EAGAIN'
+- The request could not be enqueued due to temporary lack of
+- resources.
+-
+- `EBADF'
+- The file descriptor `aiocbp->aio_fildes' is not valid or not
+- open for writing.
+-
+- `EINVAL'
+- The implementation does not support I/O synchronization or
+- the OP parameter is other than `O_DSYNC' and `O_SYNC'.
+-
+- `ENOSYS'
+- This function is not implemented.
+-
+- When the sources are compiled with `_FILE_OFFSET_BITS == 64' this
+- function is in fact `aio_fsync64' since the LFS interface
+- transparently replaces the normal implementation.
+-
+- - Function: int aio_fsync64 (int OP, struct aiocb64 *AIOCBP)
+- This function is similar to `aio_fsync' with the only difference
+- that the argument is a reference to a variable of type `struct
+- aiocb64'.
+-
+- When the sources are compiled with `_FILE_OFFSET_BITS == 64' this
+- function is available under the name `aio_fsync' and so
+- transparently replaces the interface for small files on 32 bit
+- machines.
+-
+- Another method of synchronization is to wait until one or more
+-requests of a specific set terminated. This could be achieved by the
+-`aio_*' functions to notify the initiating process about the
+-termination but in some situations this is not the ideal solution. In
+-a program which constantly updates clients somehow connected to the
+-server it is not always the best solution to go round robin since some
+-connections might be slow. On the other hand letting the `aio_*'
+-function notify the caller might also be not the best solution since
+-whenever the process works on preparing data for on client it makes no
+-sense to be interrupted by a notification since the new client will not
+-be handled before the current client is served. For situations like
+-this `aio_suspend' should be used.
+-
+- - Function: int aio_suspend (const struct aiocb *const LIST[], int
+- NENT, const struct timespec *TIMEOUT)
+- When calling this function, the calling thread is suspended until
+- at least one of the requests pointed to by the NENT elements of the
+- array LIST has completed. If any of the requests has already
+- completed at the time `aio_suspend' is called, the function returns
+- immediately. Whether a request has terminated or not is
+- determined by comparing the error status of the request with
+- `EINPROGRESS'. If an element of LIST is `NULL', the entry is
+- simply ignored.
+-
+- If no request has finished, the calling process is suspended. If
+- TIMEOUT is `NULL', the process is not woken until a request has
+- finished. If TIMEOUT is not `NULL', the process remains suspended
+- at least as long as specified in TIMEOUT. In this case,
+- `aio_suspend' returns with an error.
+-
+- The return value of the function is 0 if one or more requests from
+- the LIST have terminated. Otherwise the function returns -1 and
+- `errno' is set to one of the following values:
+-
+- `EAGAIN'
+- None of the requests from the LIST completed in the time
+- specified by TIMEOUT.
+-
+- `EINTR'
+- A signal interrupted the `aio_suspend' function. This signal
+- might also be sent by the AIO implementation while signalling
+- the termination of one of the requests.
+-
+- `ENOSYS'
+- The `aio_suspend' function is not implemented.
+-
+- When the sources are compiled with `_FILE_OFFSET_BITS == 64' this
+- function is in fact `aio_suspend64' since the LFS interface
+- transparently replaces the normal implementation.
+-
+- - Function: int aio_suspend64 (const struct aiocb64 *const LIST[], int
+- NENT, const struct timespec *TIMEOUT)
+- This function is similar to `aio_suspend' with the only difference
+- that the argument is a reference to a variable of type `struct
+- aiocb64'.
+-
+- When the sources are compiled with `_FILE_OFFSET_BITS == 64' this
+- function is available under the name `aio_suspend' and so
+- transparently replaces the interface for small files on 32 bit

+-
+-Cancellation of AIO Operations
+-------------------------------
+-
+- When one or more requests are asynchronously processed, it might be
+-useful in some situations to cancel a selected operation, e.g., if it
+-becomes obvious that the written data is no longer accurate and would
+-have to be overwritten soon. As an example, assume an application,
+-which writes data in files in a situation where new incoming data would
+-have to be written in a file which will be updated by an enqueued
+-request. The POSIX AIO implementation provides such a function, but
+-this function is not capable of forcing the cancellation of the
+-request. It is up to the implementation to decide whether it is
+-possible to cancel the operation or not. Therefore using this function
+-is merely a hint.
+-
+- - Function: int aio_cancel (int FILDES, struct aiocb *AIOCBP)
+- The `aio_cancel' function can be used to cancel one or more
+- outstanding requests. If the AIOCBP parameter is `NULL', the
+- function tries to cancel all of the outstanding requests which
+- would process the file descriptor FILDES (i.e., whose `aio_fildes'
+- member is FILDES). If AIOCBP is not `NULL', `aio_cancel' attempts
+- to cancel the specific request pointed to by AIOCBP.
+-
+- For requests which were successfully canceled, the normal
+- notification about the termination of the request should take
+- place. I.e., depending on the `struct sigevent' object which
+- controls this, nothing happens, a signal is sent or a thread is
+- started. If the request cannot be canceled, it terminates the
+- usual way after performing the operation.
+-
+- After a request is successfully canceled, a call to `aio_error'
+- with a reference to this request as the parameter will return
+- `ECANCELED' and a call to `aio_return' will return -1. If the
+- request wasn't canceled and is still running the error status is
+- still `EINPROGRESS'.
+-
+- The return value of the function is `AIO_CANCELED' if there were
+- requests which haven't terminated and which were successfully
+- canceled. If there is one or more requests left which couldn't be
+- canceled, the return value is `AIO_NOTCANCELED'. In this case
+- `aio_error' must be used to find out which of the, perhaps
+- multiple, requests (in AIOCBP is `NULL') weren't successfully
+- canceled. If all requests already terminated at the time
+- `aio_cancel' is called the return value is `AIO_ALLDONE'.
+-
+- If an error occurred during the execution of `aio_cancel' the
+- function returns -1 and sets `errno' to one of the following
+- values.
+-
+- `EBADF'
+- The file descriptor FILDES is not valid.
+-
+- `ENOSYS'
+- `aio_cancel' is not implemented.
+-
+- When the sources are compiled with `_FILE_OFFSET_BITS == 64', this
+- function is in fact `aio_cancel64' since the LFS interface
+- transparently replaces the normal implementation.
+-
+- - Function: int aio_cancel64 (int FILDES, struct aiocb64 *AIOCBP)
+- This function is similar to `aio_cancel' with the only difference
+- that the argument is a reference to a variable of type `struct
+- aiocb64'.
+-
+- When the sources are compiled with `_FILE_OFFSET_BITS == 64', this
+- function is available under the name `aio_cancel' and so
+- transparently replaces the interface for small files on 32 bit
+- machines.

+-
+-How to optimize the AIO implementation
+---------------------------------------
+-
+- The POSIX standard does not specify how the AIO functions are
+-implemented. They could be system calls, but it is also possible to
+-emulate them at userlevel.
+-
+- At the point of this writing, the available implementation is a
+-userlevel implementation which uses threads for handling the enqueued
+-requests. While this implementation requires making some decisions
+-about limitations, hard limitations are something which is best avoided
+-in the GNU C library. Therefore, the GNU C library provides a means
+-for tuning the AIO implementation according to the individual use.
+-
+- - Data Type: struct aioinit
+- This data type is used to pass the configuration or tunable
+- parameters to the implementation. The program has to initialize
+- the members of this struct and pass it to the implementation using
+- the `aio_init' function.
+-
+- `int aio_threads'
+- This member specifies the maximal number of threads which may
+- be used at any one time.
+-
+- `int aio_num'
+- This number provides an estimate on the maximal number of
+- simultaneously enqueued requests.
+-
+- `int aio_locks'
+- Unused.
+-
+- `int aio_usedba'
+- Unused.
+-
+- `int aio_debug'
+- Unused.
+-
+- `int aio_numusers'
+- Unused.
+-
+- `int aio_reserved[2]'
+- Unused.
+-
+- - Function: void aio_init (const struct aioinit *INIT)
+- This function must be called before any other AIO function.
+- Calling it is completely voluntary, as it is only meant to help
+- the AIO implementation perform better.
+-
+- Before calling the `aio_init', function the members of a variable
+- of type `struct aioinit' must be initialized. Then a reference to
+- this variable is passed as the parameter to `aio_init' which itself
+- may or may not pay attention to the hints.
+-
+- The function has no return value and no error cases are defined.
+- It is a extension which follows a proposal from the SGI
+- implementation in Irix 6. It is not covered by POSIX.1b or Unix98.

+-Control Operations on Files
+-===========================
+-
+- This section describes how you can perform various other operations
+-on file descriptors, such as inquiring about or setting flags describing
+-the status of the file descriptor, manipulating record locks, and the
+-like. All of these operations are performed by the function `fcntl'.
+-
+- The second argument to the `fcntl' function is a command that
+-specifies which operation to perform. The function and macros that name
+-various flags that are used with it are declared in the header file
+-`fcntl.h'. Many of these flags are also used by the `open' function;
+-see *Note Opening and Closing Files::.
+-
+- - Function: int fcntl (int FILEDES, int COMMAND, ...)
+- The `fcntl' function performs the operation specified by COMMAND
+- on the file descriptor FILEDES. Some commands require additional
+- arguments to be supplied. These additional arguments and the
+- return value and error conditions are given in the detailed
+- descriptions of the individual commands.
+-
+- Briefly, here is a list of what the various commands are.
+-
+- `F_DUPFD'
+- Duplicate the file descriptor (return another file descriptor
+- pointing to the same open file). *Note Duplicating
+- Descriptors::.
+-
+- `F_GETFD'
+- Get flags associated with the file descriptor. *Note
+- Descriptor Flags::.
+-
+- `F_SETFD'
+- Set flags associated with the file descriptor. *Note
+- Descriptor Flags::.
+-
+- `F_GETFL'
+- Get flags associated with the open file. *Note File Status
+- Flags::.
+-
+- `F_SETFL'
+- Set flags associated with the open file. *Note File Status
+- Flags::.
+-
+- `F_GETLK'
+- Get a file lock. *Note File Locks::.
+-
+- `F_SETLK'
+- Set or clear a file lock. *Note File Locks::.
+-
+- `F_SETLKW'
+- Like `F_SETLK', but wait for completion. *Note File Locks::.
+-
+- `F_GETOWN'
+- Get process or process group ID to receive `SIGIO' signals.
+- *Note Interrupt Input::.
+-
+- `F_SETOWN'
+- Set process or process group ID to receive `SIGIO' signals.
+- *Note Interrupt Input::.
+-
+- This function is a cancellation point in multi-threaded programs.
+- This is a problem if the thread allocates some resources (like
+- memory, file descriptors, semaphores or whatever) at the time
+- `fcntl' is called. If the thread gets canceled these resources
+- stay allocated until the program ends. To avoid this calls to
+- `fcntl' should be protected using cancellation handlers.

+-
+-Duplicating Descriptors
+-=======================
+-
+- You can "duplicate" a file descriptor, or allocate another file
+-descriptor that refers to the same open file as the original. Duplicate
+-descriptors share one file position and one set of file status flags
+-(*note File Status Flags::), but each has its own set of file descriptor
+-flags (*note Descriptor Flags::).
+-
+- The major use of duplicating a file descriptor is to implement
+-"redirection" of input or output: that is, to change the file or pipe
+-that a particular file descriptor corresponds to.
+-
+- You can perform this operation using the `fcntl' function with the
+-`F_DUPFD' command, but there are also convenient functions `dup' and
+-`dup2' for duplicating descriptors.
+-
+- The `fcntl' function and flags are declared in `fcntl.h', while
+-prototypes for `dup' and `dup2' are in the header file `unistd.h'.
+-
+- - Function: int dup (int OLD)
+- This function copies descriptor OLD to the first available
+- descriptor number (the first number not currently open). It is
+- equivalent to `fcntl (OLD, F_DUPFD, 0)'.
+-
+- - Function: int dup2 (int OLD, int NEW)
+- This function copies the descriptor OLD to descriptor number NEW.
+-
+- If OLD is an invalid descriptor, then `dup2' does nothing; it does
+- not close NEW. Otherwise, the new duplicate of OLD replaces any
+- previous meaning of descriptor NEW, as if NEW were closed first.
+-
+- If OLD and NEW are different numbers, and OLD is a valid
+- descriptor number, then `dup2' is equivalent to:
+-
+- close (NEW);
+- fcntl (OLD, F_DUPFD, NEW)
+-
+- However, `dup2' does this atomically; there is no instant in the
+- middle of calling `dup2' at which NEW is closed and not yet a
+- duplicate of OLD.
+-
+- - Macro: int F_DUPFD
+- This macro is used as the COMMAND argument to `fcntl', to copy the
+- file descriptor given as the first argument.
+-
+- The form of the call in this case is:
+-
+- fcntl (OLD, F_DUPFD, NEXT-FILEDES)
+-
+- The NEXT-FILEDES argument is of type `int' and specifies that the
+- file descriptor returned should be the next available one greater
+- than or equal to this value.
+-
+- The return value from `fcntl' with this command is normally the
+- value of the new file descriptor. A return value of -1 indicates
+- an error. The following `errno' error conditions are defined for
+- this command:
+-
+- `EBADF'
+- The OLD argument is invalid.
+-
+- `EINVAL'
+- The NEXT-FILEDES argument is invalid.
+-
+- `EMFILE'
+- There are no more file descriptors available--your program is
+- already using the maximum. In BSD and GNU, the maximum is
+- controlled by a resource limit that can be changed; *note
+- Limits on Resources::, for more information about the
+- `RLIMIT_NOFILE' limit.
+-
+- `ENFILE' is not a possible error code for `dup2' because `dup2'
+- does not create a new opening of a file; duplicate descriptors do
+- not count toward the limit which `ENFILE' indicates. `EMFILE' is
+- possible because it refers to the limit on distinct descriptor
+- numbers in use in one process.
+-
+- Here is an example showing how to use `dup2' to do redirection.
+-Typically, redirection of the standard streams (like `stdin') is done
+-by a shell or shell-like program before calling one of the `exec'
+-functions (*note Executing a File::) to execute a new program in a
+-child process. When the new program is executed, it creates and
+-initializes the standard streams to point to the corresponding file
+-descriptors, before its `main' function is invoked.
+-
+- So, to redirect standard input to a file, the shell could do
+-something like:
+-
+- pid = fork ();
+- if (pid == 0)
+- {
+- char *filename;
+- char *program;
+- int file;
+- ...
+- file = TEMP_FAILURE_RETRY (open (filename, O_RDONLY));
+- dup2 (file, STDIN_FILENO);
+- TEMP_FAILURE_RETRY (close (file));
+- execv (program, NULL);
+- }
+-
+- There is also a more detailed example showing how to implement
+-redirection in the context of a pipeline of processes in *Note
+-Launching Jobs::.

+-
+-File Descriptor Flags
+-=====================
+-
+- "File descriptor flags" are miscellaneous attributes of a file
+-descriptor. These flags are associated with particular file
+-descriptors, so that if you have created duplicate file descriptors
+-from a single opening of a file, each descriptor has its own set of
+-flags.
+-
+- Currently there is just one file descriptor flag: `FD_CLOEXEC',
+-which causes the descriptor to be closed if you use any of the
+-`exec...' functions (*note Executing a File::).
+-
+- The symbols in this section are defined in the header file `fcntl.h'.
+-
+- - Macro: int F_GETFD
+- This macro is used as the COMMAND argument to `fcntl', to specify
+- that it should return the file descriptor flags associated with
+- the FILEDES argument.
+-
+- The normal return value from `fcntl' with this command is a
+- nonnegative number which can be interpreted as the bitwise OR of
+- the individual flags (except that currently there is only one flag
+- to use).
+-
+- In case of an error, `fcntl' returns -1. The following `errno'
+- error conditions are defined for this command:
+-
+- `EBADF'
+- The FILEDES argument is invalid.
+-
+- - Macro: int F_SETFD
+- This macro is used as the COMMAND argument to `fcntl', to specify
+- that it should set the file descriptor flags associated with the
+- FILEDES argument. This requires a third `int' argument to specify
+- the new flags, so the form of the call is:
+-
+- fcntl (FILEDES, F_SETFD, NEW-FLAGS)
+-
+- The normal return value from `fcntl' with this command is an
+- unspecified value other than -1, which indicates an error. The
+- flags and error conditions are the same as for the `F_GETFD'
+- command.
+-
+- The following macro is defined for use as a file descriptor flag with
+-the `fcntl' function. The value is an integer constant usable as a bit
+-mask value.
+-
+- - Macro: int FD_CLOEXEC
+- This flag specifies that the file descriptor should be closed when
+- an `exec' function is invoked; see *Note Executing a File::. When
+- a file descriptor is allocated (as with `open' or `dup'), this bit
+- is initially cleared on the new file descriptor, meaning that
+- descriptor will survive into the new program after `exec'.
+-
+- If you want to modify the file descriptor flags, you should get the
+-current flags with `F_GETFD' and modify the value. Don't assume that
+-the flags listed here are the only ones that are implemented; your
+-program may be run years from now and more flags may exist then. For
+-example, here is a function to set or clear the flag `FD_CLOEXEC'
+-without altering any other flags:
+-
+- /* Set the `FD_CLOEXEC' flag of DESC if VALUE is nonzero,
+- or clear the flag if VALUE is 0.
+- Return 0 on success, or -1 on error with `errno' set. */
+-
+- int
+- set_cloexec_flag (int desc, int value)
+- {
+- int oldflags = fcntl (desc, F_GETFD, 0);
+- /* If reading the flags failed, return error indication now. */
+- if (oldflags < 0)
+- return oldflags;
+- /* Set just the flag we want to set. */
+- if (value != 0)
+- oldflags |= FD_CLOEXEC;
+- else
+- oldflags &= ~FD_CLOEXEC;
+- /* Store modified flag word in the descriptor. */
+- return fcntl (desc, F_SETFD, oldflags);
+- }

+-File Status Flags
+-=================
+-
+- "File status flags" are used to specify attributes of the opening of
+-a file. Unlike the file descriptor flags discussed in *Note Descriptor
+-Flags::, the file status flags are shared by duplicated file descriptors
+-resulting from a single opening of the file. The file status flags are
+-specified with the FLAGS argument to `open'; *note Opening and Closing
+-Files::.
+-
+- File status flags fall into three categories, which are described in
+-the following sections.
+-
+- * *Note Access Modes::, specify what type of access is allowed to the
+- file: reading, writing, or both. They are set by `open' and are
+- returned by `fcntl', but cannot be changed.
+-
+- * *Note Open-time Flags::, control details of what `open' will do.
+- These flags are not preserved after the `open' call.
+-
+- * *Note Operating Modes::, affect how operations such as `read' and
+- `write' are done. They are set by `open', and can be fetched or
+- changed with `fcntl'.
+-
+- The symbols in this section are defined in the header file `fcntl.h'.

+-
+-* Access Modes:: Whether the descriptor can read or write.

+-File Access Modes
+------------------
+-
+- The file access modes allow a file descriptor to be used for reading,
+-writing, or both. (In the GNU system, they can also allow none of
+-these, and allow execution of the file as a program.) The access modes
+-are chosen when the file is opened, and never change.

+- - Macro: int O_WRONLY
+- Open the file for write access.
+-
+- - Macro: int O_RDWR
+- Open the file for both reading and writing.
+-
+- In the GNU system (and not in other systems), `O_RDONLY' and
+-`O_WRONLY' are independent bits that can be bitwise-ORed together, and
+-it is valid for either bit to be set or clear. This means that
+-`O_RDWR' is the same as `O_RDONLY|O_WRONLY'. A file access mode of
+-zero is permissible; it allows no operations that do input or output to
+-the file, but does allow other operations such as `fchmod'. On the GNU
+-system, since "read-only" or "write-only" is a misnomer, `fcntl.h'
+-defines additional names for the file access modes. These names are
+-preferred when writing GNU-specific code. But most programs will want
+-to be portable to other POSIX.1 systems and should use the POSIX.1
+-names above instead.
+-
+- - Macro: int O_READ
+- Open the file for reading. Same as `O_RDONLY'; only defined on
+- GNU.
+-
+- - Macro: int O_WRITE
+- Open the file for writing. Same as `O_WRONLY'; only defined on
+- GNU.
+-
+- - Macro: int O_EXEC
+- Open the file for executing. Only defined on GNU.
+-
+- To determine the file access mode with `fcntl', you must extract the
+-access mode bits from the retrieved file status flags. In the GNU
+-system, you can just test the `O_READ' and `O_WRITE' bits in the flags
+-word. But in other POSIX.1 systems, reading and writing access modes
+-are not stored as distinct bit flags. The portable way to extract the
+-file access mode bits is with `O_ACCMODE'.
+-
+- - Macro: int O_ACCMODE
+- This macro stands for a mask that can be bitwise-ANDed with the
+- file status flag value to produce a value representing the file
+- access mode. The mode will be `O_RDONLY', `O_WRONLY', or `O_RDWR'.
+- (In the GNU system it could also be zero, and it never includes the
+- `O_EXEC' bit.)

+-
+-Open-time Flags
+----------------
+-
+- The open-time flags specify options affecting how `open' will behave.
+-These options are not preserved once the file is open. The exception to
+-this is `O_NONBLOCK', which is also an I/O operating mode and so it
+-_is_ saved. *Note Opening and Closing Files::, for how to call `open'.
+-
+- There are two sorts of options specified by open-time flags.
+-
+- * "File name translation flags" affect how `open' looks up the file
+- name to locate the file, and whether the file can be created.
+-
+- * "Open-time action flags" specify extra operations that `open' will
+- perform on the file once it is open.
+-
+- Here are the file name translation flags.
+-
+- - Macro: int O_CREAT
+- If set, the file will be created if it doesn't already exist.
+-
+- - Macro: int O_EXCL
+- If both `O_CREAT' and `O_EXCL' are set, then `open' fails if the
+- specified file already exists. This is guaranteed to never
+- clobber an existing file.
+-
+- - Macro: int O_NONBLOCK
+- This prevents `open' from blocking for a "long time" to open the
+- file. This is only meaningful for some kinds of files, usually
+- devices such as serial ports; when it is not meaningful, it is
+- harmless and ignored. Often opening a port to a modem blocks
+- until the modem reports carrier detection; if `O_NONBLOCK' is
+- specified, `open' will return immediately without a carrier.
+-
+- Note that the `O_NONBLOCK' flag is overloaded as both an I/O
+- operating mode and a file name translation flag. This means that
+- specifying `O_NONBLOCK' in `open' also sets nonblocking I/O mode;
+- *note Operating Modes::. To open the file without blocking but do
+- normal I/O that blocks, you must call `open' with `O_NONBLOCK' set
+- and then call `fcntl' to turn the bit off.
+-
+- - Macro: int O_NOCTTY
+- If the named file is a terminal device, don't make it the
+- controlling terminal for the process. *Note Job Control::, for
+- information about what it means to be the controlling terminal.
+-
+- In the GNU system and 4.4 BSD, opening a file never makes it the
+- controlling terminal and `O_NOCTTY' is zero. However, other
+- systems may use a nonzero value for `O_NOCTTY' and set the
+- controlling terminal when you open a file that is a terminal
+- device; so to be portable, use `O_NOCTTY' when it is important to
+- avoid this.
+-
+- The following three file name translation flags exist only in the
+-GNU system.
+-
+- - Macro: int O_IGNORE_CTTY
+- Do not recognize the named file as the controlling terminal, even
+- if it refers to the process's existing controlling terminal
+- device. Operations on the new file descriptor will never induce
+- job control signals. *Note Job Control::.
+-
+- - Macro: int O_NOLINK
+- If the named file is a symbolic link, open the link itself instead
+- of the file it refers to. (`fstat' on the new file descriptor will
+- return the information returned by `lstat' on the link's name.)
+-
+- - Macro: int O_NOTRANS
+- If the named file is specially translated, do not invoke the
+- translator. Open the bare file the translator itself sees.
+-
+- The open-time action flags tell `open' to do additional operations
+-which are not really related to opening the file. The reason to do them
+-as part of `open' instead of in separate calls is that `open' can do
+-them atomically.
+-
+- - Macro: int O_TRUNC
+- Truncate the file to zero length. This option is only useful for
+- regular files, not special files such as directories or FIFOs.
+- POSIX.1 requires that you open the file for writing to use
+- `O_TRUNC'. In BSD and GNU you must have permission to write the
+- file to truncate it, but you need not open for write access.
+-
+- This is the only open-time action flag specified by POSIX.1.
+- There is no good reason for truncation to be done by `open',
+- instead of by calling `ftruncate' afterwards. The `O_TRUNC' flag
+- existed in Unix before `ftruncate' was invented, and is retained
+- for backward compatibility.
+-
+- The remaining operating modes are BSD extensions. They exist only
+-on some systems. On other systems, these macros are not defined.
+-
+- - Macro: int O_SHLOCK
+- Acquire a shared lock on the file, as with `flock'. *Note File
+- Locks::.
+-
+- If `O_CREAT' is specified, the locking is done atomically when
+- creating the file. You are guaranteed that no other process will
+- get the lock on the new file first.
+-
+- - Macro: int O_EXLOCK
+- Acquire an exclusive lock on the file, as with `flock'. *Note
+- File Locks::. This is atomic like `O_SHLOCK'.

+-
+-I/O Operating Modes
+--------------------
+-
+- The operating modes affect how input and output operations using a
+-file descriptor work. These flags are set by `open' and can be fetched
+-and changed with `fcntl'.
+-
+- - Macro: int O_APPEND
+- The bit that enables append mode for the file. If set, then all
+- `write' operations write the data at the end of the file, extending
+- it, regardless of the current file position. This is the only
+- reliable way to append to a file. In append mode, you are
+- guaranteed that the data you write will always go to the current
+- end of the file, regardless of other processes writing to the
+- file. Conversely, if you simply set the file position to the end
+- of file and write, then another process can extend the file after
+- you set the file position but before you write, resulting in your
+- data appearing someplace before the real end of file.
+-
+- - Macro: int O_NONBLOCK
+- The bit that enables nonblocking mode for the file. If this bit
+- is set, `read' requests on the file can return immediately with a
+- failure status if there is no input immediately available, instead
+- of blocking. Likewise, `write' requests can also return
+- immediately with a failure status if the output can't be written
+- immediately.
+-
+- Note that the `O_NONBLOCK' flag is overloaded as both an I/O
+- operating mode and a file name translation flag; *note Open-time
+- Flags::.
+-
+- - Macro: int O_NDELAY
+- This is an obsolete name for `O_NONBLOCK', provided for
+- compatibility with BSD. It is not defined by the POSIX.1 standard.
+-
+- The remaining operating modes are BSD and GNU extensions. They
+-exist only on some systems. On other systems, these macros are not
+-defined.
+-
+- - Macro: int O_ASYNC
+- The bit that enables asynchronous input mode. If set, then `SIGIO'
+- signals will be generated when input is available. *Note
+- Interrupt Input::.
+-
+- Asynchronous input mode is a BSD feature.
+-
+- - Macro: int O_FSYNC
+- The bit that enables synchronous writing for the file. If set,
+- each `write' call will make sure the data is reliably stored on
+- disk before returning. Synchronous writing is a BSD feature.
+-
+- - Macro: int O_SYNC
+- This is another name for `O_FSYNC'. They have the same value.
+-
+- - Macro: int O_NOATIME
+- If this bit is set, `read' will not update the access time of the
+- file. *Note File Times::. This is used by programs that do
+- backups, so that backing a file up does not count as reading it.
+- Only the owner of the file or the superuser may use this bit.
+-
+- This is a GNU extension.

+-
+-Getting and Setting File Status Flags
+--------------------------------------
+-
+- The `fcntl' function can fetch or change file status flags.
+-
+- - Macro: int F_GETFL
+- This macro is used as the COMMAND argument to `fcntl', to read the
+- file status flags for the open file with descriptor FILEDES.
+-
+- The normal return value from `fcntl' with this command is a
+- nonnegative number which can be interpreted as the bitwise OR of
+- the individual flags. Since the file access modes are not
+- single-bit values, you can mask off other bits in the returned
+- flags with `O_ACCMODE' to compare them.
+-
+- In case of an error, `fcntl' returns -1. The following `errno'
+- error conditions are defined for this command:
+-
+- `EBADF'
+- The FILEDES argument is invalid.
+-
+- - Macro: int F_SETFL
+- This macro is used as the COMMAND argument to `fcntl', to set the
+- file status flags for the open file corresponding to the FILEDES
+- argument. This command requires a third `int' argument to specify
+- the new flags, so the call looks like this:
+-
+- fcntl (FILEDES, F_SETFL, NEW-FLAGS)
+-
+- You can't change the access mode for the file in this way; that is,
+- whether the file descriptor was opened for reading or writing.
+-
+- The normal return value from `fcntl' with this command is an
+- unspecified value other than -1, which indicates an error. The
+- error conditions are the same as for the `F_GETFL' command.
+-
+- If you want to modify the file status flags, you should get the
+-current flags with `F_GETFL' and modify the value. Don't assume that
+-the flags listed here are the only ones that are implemented; your
+-program may be run years from now and more flags may exist then. For
+-example, here is a function to set or clear the flag `O_NONBLOCK'
+-without altering any other flags:
+-
+- /* Set the `O_NONBLOCK' flag of DESC if VALUE is nonzero,
+- or clear the flag if VALUE is 0.
+- Return 0 on success, or -1 on error with `errno' set. */
+-
+- int
+- set_nonblock_flag (int desc, int value)
+- {
+- int oldflags = fcntl (desc, F_GETFL, 0);
+- /* If reading the flags failed, return error indication now. */
+- if (oldflags == -1)
+- return -1;
+- /* Set just the flag we want to set. */
+- if (value != 0)
+- oldflags |= O_NONBLOCK;
+- else
+- oldflags &= ~O_NONBLOCK;
+- /* Store modified flag word in the descriptor. */
+- return fcntl (desc, F_SETFL, oldflags);
+- }

+-
+-File Locks
+-==========
+-
+- The remaining `fcntl' commands are used to support "record locking",
+-which permits multiple cooperating programs to prevent each other from
+-simultaneously accessing parts of a file in error-prone ways.
+-
+- An "exclusive" or "write" lock gives a process exclusive access for
+-writing to the specified part of the file. While a write lock is in
+-place, no other process can lock that part of the file.
+-
+- A "shared" or "read" lock prohibits any other process from
+-requesting a write lock on the specified part of the file. However,
+-other processes can request read locks.
+-
+- The `read' and `write' functions do not actually check to see
+-whether there are any locks in place. If you want to implement a
+-locking protocol for a file shared by multiple processes, your
+-application must do explicit `fcntl' calls to request and clear locks
+-at the appropriate points.
+-
+- Locks are associated with processes. A process can only have one
+-kind of lock set for each byte of a given file. When any file
+-descriptor for that file is closed by the process, all of the locks
+-that process holds on that file are released, even if the locks were
+-made using other descriptors that remain open. Likewise, locks are
+-released when a process exits, and are not inherited by child processes
+-created using `fork' (*note Creating a Process::).
+-
+- When making a lock, use a `struct flock' to specify what kind of
+-lock and where. This data type and the associated macros for the
+-`fcntl' function are declared in the header file `fcntl.h'.
+-
+- - Data Type: struct flock
+- This structure is used with the `fcntl' function to describe a file
+- lock. It has these members:
+-
+- `short int l_type'
+- Specifies the type of the lock; one of `F_RDLCK', `F_WRLCK',
+- or `F_UNLCK'.
+-
+- `short int l_whence'
+- This corresponds to the WHENCE argument to `fseek' or
+- `lseek', and specifies what the offset is relative to. Its
+- value can be one of `SEEK_SET', `SEEK_CUR', or `SEEK_END'.
+-
+- `off_t l_start'
+- This specifies the offset of the start of the region to which
+- the lock applies, and is given in bytes relative to the point
+- specified by `l_whence' member.
+-
+- `off_t l_len'
+- This specifies the length of the region to be locked. A
+- value of `0' is treated specially; it means the region
+- extends to the end of the file.
+-
+- `pid_t l_pid'
+- This field is the process ID (*note Process Creation
+- Concepts::) of the process holding the lock. It is filled in
+- by calling `fcntl' with the `F_GETLK' command, but is ignored
+- when making a lock.
+-
+- - Macro: int F_GETLK
+- This macro is used as the COMMAND argument to `fcntl', to specify
+- that it should get information about a lock. This command
+- requires a third argument of type `struct flock *' to be passed to
+- `fcntl', so that the form of the call is:
+-
+- fcntl (FILEDES, F_GETLK, LOCKP)
+-
+- If there is a lock already in place that would block the lock
+- described by the LOCKP argument, information about that lock
+- overwrites `*LOCKP'. Existing locks are not reported if they are
+- compatible with making a new lock as specified. Thus, you should
+- specify a lock type of `F_WRLCK' if you want to find out about both
+- read and write locks, or `F_RDLCK' if you want to find out about
+- write locks only.
+-
+- There might be more than one lock affecting the region specified
+- by the LOCKP argument, but `fcntl' only returns information about
+- one of them. The `l_whence' member of the LOCKP structure is set
+- to `SEEK_SET' and the `l_start' and `l_len' fields set to identify
+- the locked region.
+-
+- If no lock applies, the only change to the LOCKP structure is to
+- update the `l_type' to a value of `F_UNLCK'.
+-
+- The normal return value from `fcntl' with this command is an
+- unspecified value other than -1, which is reserved to indicate an
+- error. The following `errno' error conditions are defined for
+- this command:
+-
+- `EBADF'
+- The FILEDES argument is invalid.
+-
+- `EINVAL'
+- Either the LOCKP argument doesn't specify valid lock
+- information, or the file associated with FILEDES doesn't
+- support locks.
+-
+- - Macro: int F_SETLK
+- This macro is used as the COMMAND argument to `fcntl', to specify
+- that it should set or clear a lock. This command requires a third
+- argument of type `struct flock *' to be passed to `fcntl', so that
+- the form of the call is:
+-
+- fcntl (FILEDES, F_SETLK, LOCKP)
+-
+- If the process already has a lock on any part of the region, the
+- old lock on that part is replaced with the new lock. You can
+- remove a lock by specifying a lock type of `F_UNLCK'.
+-
+- If the lock cannot be set, `fcntl' returns immediately with a value
+- of -1. This function does not block waiting for other processes
+- to release locks. If `fcntl' succeeds, it return a value other
+- than -1.
+-
+- The following `errno' error conditions are defined for this
+- function:
+-
+- `EAGAIN'
+- `EACCES'
+- The lock cannot be set because it is blocked by an existing
+- lock on the file. Some systems use `EAGAIN' in this case,
+- and other systems use `EACCES'; your program should treat
+- them alike, after `F_SETLK'. (The GNU system always uses
+- `EAGAIN'.)
+-
+- `EBADF'
+- Either: the FILEDES argument is invalid; you requested a read
+- lock but the FILEDES is not open for read access; or, you
+- requested a write lock but the FILEDES is not open for write
+- access.
+-
+- `EINVAL'
+- Either the LOCKP argument doesn't specify valid lock
+- information, or the file associated with FILEDES doesn't
+- support locks.
+-
+- `ENOLCK'
+- The system has run out of file lock resources; there are
+- already too many file locks in place.
+-
+- Well-designed file systems never report this error, because
+- they have no limitation on the number of locks. However, you
+- must still take account of the possibility of this error, as
+- it could result from network access to a file system on
+- another machine.
+-
+- - Macro: int F_SETLKW
+- This macro is used as the COMMAND argument to `fcntl', to specify
+- that it should set or clear a lock. It is just like the `F_SETLK'
+- command, but causes the process to block (or wait) until the
+- request can be specified.
+-
+- This command requires a third argument of type `struct flock *', as
+- for the `F_SETLK' command.
+-
+- The `fcntl' return values and errors are the same as for the
+- `F_SETLK' command, but these additional `errno' error conditions
+- are defined for this command:
+-
+- `EINTR'
+- The function was interrupted by a signal while it was waiting.
+- *Note Interrupted Primitives::.
+-
+- `EDEADLK'
+- The specified region is being locked by another process. But
+- that process is waiting to lock a region which the current
+- process has locked, so waiting for the lock would result in
+- deadlock. The system does not guarantee that it will detect
+- all such conditions, but it lets you know if it notices one.
+-
+- The following macros are defined for use as values for the `l_type'
+-member of the `flock' structure. The values are integer constants.
+-
+-`F_RDLCK'
+- This macro is used to specify a read (or shared) lock.
+-
+-`F_WRLCK'
+- This macro is used to specify a write (or exclusive) lock.
+-
+-`F_UNLCK'
+- This macro is used to specify that the region is unlocked.
+-
+- As an example of a situation where file locking is useful, consider a
+-program that can be run simultaneously by several different users, that
+-logs status information to a common file. One example of such a program
+-might be a game that uses a file to keep track of high scores. Another
+-example might be a program that records usage or accounting information
+-for billing purposes.
+-
+- Having multiple copies of the program simultaneously writing to the
+-file could cause the contents of the file to become mixed up. But you
+-can prevent this kind of problem by setting a write lock on the file
+-before actually writing to the file.
+-
+- If the program also needs to read the file and wants to make sure
+-that the contents of the file are in a consistent state, then it can
+-also use a read lock. While the read lock is set, no other process can
+-lock that part of the file for writing.
+-
+- Remember that file locks are only a _voluntary_ protocol for
+-controlling access to a file. There is still potential for access to
+-the file by programs that don't use the lock protocol.

+-Interrupt-Driven Input
+-======================
+-
+- If you set the `O_ASYNC' status flag on a file descriptor (*note
+-File Status Flags::), a `SIGIO' signal is sent whenever input or output
+-becomes possible on that file descriptor. The process or process group
+-to receive the signal can be selected by using the `F_SETOWN' command
+-to the `fcntl' function. If the file descriptor is a socket, this also
+-selects the recipient of `SIGURG' signals that are delivered when
+-out-of-band data arrives on that socket; see *Note Out-of-Band Data::.
+-(`SIGURG' is sent in any situation where `select' would report the
+-socket as having an "exceptional condition". *Note Waiting for I/O::.)
+-
+- If the file descriptor corresponds to a terminal device, then `SIGIO'
+-signals are sent to the foreground process group of the terminal.
+-*Note Job Control::.
+-
+- The symbols in this section are defined in the header file `fcntl.h'.
+-
+- - Macro: int F_GETOWN
+- This macro is used as the COMMAND argument to `fcntl', to specify
+- that it should get information about the process or process group
+- to which `SIGIO' signals are sent. (For a terminal, this is
+- actually the foreground process group ID, which you can get using
+- `tcgetpgrp'; see *Note Terminal Access Functions::.)
+-
+- The return value is interpreted as a process ID; if negative, its
+- absolute value is the process group ID.
+-
+- The following `errno' error condition is defined for this command:
+-
+- `EBADF'
+- The FILEDES argument is invalid.
+-
+- - Macro: int F_SETOWN
+- This macro is used as the COMMAND argument to `fcntl', to specify
+- that it should set the process or process group to which `SIGIO'
+- signals are sent. This command requires a third argument of type
+- `pid_t' to be passed to `fcntl', so that the form of the call is:
+-
+- fcntl (FILEDES, F_SETOWN, PID)
+-
+- The PID argument should be a process ID. You can also pass a
+- negative number whose absolute value is a process group ID.
+-
+- The return value from `fcntl' with this command is -1 in case of
+- error and some other value if successful. The following `errno'
+- error conditions are defined for this command:
+-
+- `EBADF'
+- The FILEDES argument is invalid.
+-
+- `ESRCH'
+- There is no process or process group corresponding to PID.

+-
+-Generic I/O Control operations
+-==============================
+-
+- The GNU system can handle most input/output operations on many
+-different devices and objects in terms of a few file primitives -
+-`read', `write' and `lseek'. However, most devices also have a few
+-peculiar operations which do not fit into this model. Such as:
+-
+- * Changing the character font used on a terminal.
+-
+- * Telling a magnetic tape system to rewind or fast forward. (Since
+- they cannot move in byte increments, `lseek' is inapplicable).
+-
+- * Ejecting a disk from a drive.
+-
+- * Playing an audio track from a CD-ROM drive.
+-
+- * Maintaining routing tables for a network.
+-
+-
+- Although some such objects such as sockets and terminals (1) have
+-special functions of their own, it would not be practical to create
+-functions for all these cases.
+-
+- Instead these minor operations, known as "IOCTL"s, are assigned code
+-numbers and multiplexed through the `ioctl' function, defined in
+-`sys/ioctl.h'. The code numbers themselves are defined in many
+-different headers.
+-
+- - Function: int ioctl (int FILEDES, int COMMAND, ...)
+- The `ioctl' function performs the generic I/O operation COMMAND on
+- FILEDES.
+-
+- A third argument is usually present, either a single number or a
+- pointer to a structure. The meaning of this argument, the
+- returned value, and any error codes depends upon the command used.
+- Often -1 is returned for a failure.
+-
+-
+- On some systems, IOCTLs used by different devices share the same
+-numbers. Thus, although use of an inappropriate IOCTL _usually_ only
+-produces an error, you should not attempt to use device-specific IOCTLs
+-on an unknown device.
+-
+- Most IOCTLs are OS-specific and/or only used in special system
+-utilities, and are thus beyond the scope of this document. For an
+-example of the use of an IOCTL, see *Note Out-of-Band Data::.
+-
+- ---------- Footnotes ----------
+-
+- (1) Actually, the terminal-specific functions are implemented with
+-IOCTLs on many platforms.

+-the files themselves rather than on their contents.
+-
+- Among the facilities described in this chapter are functions for
+-examining or modifying directories, functions for renaming and deleting
+-files, and functions for examining and setting file attributes such as
+-access permissions and modification times.
+-
+-* Menu:
+-
+-* Working Directory:: This is used to resolve relative

+-Working Directory
+-=================
+-
+- Each process has associated with it a directory, called its "current
+-working directory" or simply "working directory", that is used in the
+-resolution of relative file names (*note File Name Resolution::).
+-
+- When you log in and begin a new session, your working directory is
+-initially set to the home directory associated with your login account
+-in the system user database. You can find any user's home directory
+-using the `getpwuid' or `getpwnam' functions; see *Note User Database::.
+-
+- Users can change the working directory using shell commands like
+-`cd'. The functions described in this section are the primitives used
+-by those commands and by other programs for examining and changing the
+-working directory.
+-
+- Prototypes for these functions are declared in the header file
+-`unistd.h'.
+-
+- - Function: char * getcwd (char *BUFFER, size_t SIZE)
+- The `getcwd' function returns an absolute file name representing
+- the current working directory, storing it in the character array
+- BUFFER that you provide. The SIZE argument is how you tell the
+- system the allocation size of BUFFER.
+-
+- The GNU library version of this function also permits you to
+- specify a null pointer for the BUFFER argument. Then `getcwd'
+- allocates a buffer automatically, as with `malloc' (*note
+- Unconstrained Allocation::). If the SIZE is greater than zero,
+- then the buffer is that large; otherwise, the buffer is as large
+- as necessary to hold the result.
+-
+- The return value is BUFFER on success and a null pointer on
+- failure. The following `errno' error conditions are defined for
+- this function:
+-
+- `EINVAL'
+- The SIZE argument is zero and BUFFER is not a null pointer.
+-
+- `ERANGE'
+- The SIZE argument is less than the length of the working
+- directory name. You need to allocate a bigger array and try
+- again.
+-
+- `EACCES'
+- Permission to read or search a component of the file name was
+- denied.
+-
+- You could implement the behavior of GNU's `getcwd (NULL, 0)' using
+-only the standard behavior of `getcwd':
+-
+- char *
+- gnu_getcwd ()
+- {
+- size_t size = 100;
+-
+- while (1)
+- {
+- char *buffer = (char *) xmalloc (size);
+- if (getcwd (buffer, size) == buffer)
+- return buffer;
+- free (buffer);
+- if (errno != ERANGE)
+- return 0;
+- size *= 2;
+- }
+- }
+-
+-*Note Malloc Examples::, for information about `xmalloc', which is not
+-a library function but is a customary name used in most GNU software.
+-
+- - Deprecated Function: char * getwd (char *BUFFER)
+- This is similar to `getcwd', but has no way to specify the size of
+- the buffer. The GNU library provides `getwd' only for backwards
+- compatibility with BSD.
+-
+- The BUFFER argument should be a pointer to an array at least
+- `PATH_MAX' bytes long (*note Limits for Files::). In the GNU
+- system there is no limit to the size of a file name, so this is not
+- necessarily enough space to contain the directory name. That is
+- why this function is deprecated.
+-
+- - Function: char * get_current_dir_name (void)
+- This `get_current_dir_name' function is bascially equivalent to
+- `getcwd (NULL, 0)'. The only difference is that the value of the
+- `PWD' variable is returned if this value is correct. This is a
+- subtle difference which is visible if the path described by the
+- `PWD' value is using one or more symbol links in which case the
+- value returned by `getcwd' can resolve the symbol links and
+- therefore yield a different result.
+-
+- This function is a GNU extension.
+-
+- - Function: int chdir (const char *FILENAME)
+- This function is used to set the process's working directory to
+- FILENAME.
+-
+- The normal, successful return value from `chdir' is `0'. A value
+- of `-1' is returned to indicate an error. The `errno' error
+- conditions defined for this function are the usual file name
+- syntax errors (*note File Name Errors::), plus `ENOTDIR' if the
+- file FILENAME is not a directory.
+-
+- - Function: int fchdir (int FILEDES)
+- This function is used to set the process's working directory to
+- directory associated with the file descriptor FILEDES.
+-
+- The normal, successful return value from `fchdir' is `0'. A value
+- of `-1' is returned to indicate an error. The following `errno'
+- error conditions are defined for this function:
+-
+- `EACCES'
+- Read permission is denied for the directory named by
+- `dirname'.
+-
+- `EBADF'
+- The FILEDES argument is not a valid file descriptor.
+-
+- `ENOTDIR'
+- The file descriptor FILEDES is not associated with a
+- directory.
+-
+- `EINTR'
+- The function call was interrupt by a signal.
+-
+- `EIO'
+- An I/O error occurred.

+-Accessing Directories
+-=====================
+-
+- The facilities described in this section let you read the contents
+-of a directory file. This is useful if you want your program to list
+-all the files in a directory, perhaps as part of a menu.
+-
+- The `opendir' function opens a "directory stream" whose elements are
+-directory entries. You use the `readdir' function on the directory
+-stream to retrieve these entries, represented as `struct dirent'
+-objects. The name of the file for each entry is stored in the `d_name'
+-member of this structure. There are obvious parallels here to the
+-stream facilities for ordinary files, described in *Note I/O on
+-Streams::.

+-Format of a Directory Entry
+----------------------------
+-
+- This section describes what you find in a single directory entry, as
+-you might obtain it from a directory stream. All the symbols are
+-declared in the header file `dirent.h'.
+-
+- - Data Type: struct dirent
+- This is a structure type used to return information about directory
+- entries. It contains the following fields:
+-
+- `char d_name[]'
+- This is the null-terminated file name component. This is the
+- only field you can count on in all POSIX systems.
+-
+- `ino_t d_fileno'
+- This is the file serial number. For BSD compatibility, you
+- can also refer to this member as `d_ino'. In the GNU system
+- and most POSIX systems, for most files this the same as the
+- `st_ino' member that `stat' will return for the file. *Note
+- File Attributes::.
+-
+- `unsigned char d_namlen'
+- This is the length of the file name, not including the
+- terminating null character. Its type is `unsigned char'
+- because that is the integer type of the appropriate size
+-
+- `unsigned char d_type'
+- This is the type of the file, possibly unknown. The
+- following constants are defined for its value:
+-
+- `DT_UNKNOWN'
+- The type is unknown. On some systems this is the only
+- value returned.
+-
+- `DT_REG'
+- A regular file.
+-
+- `DT_DIR'
+- A directory.
+-
+- `DT_FIFO'
+- A named pipe, or FIFO. *Note FIFO Special Files::.
+-
+- `DT_SOCK'
+- A local-domain socket.
+-
+- `DT_CHR'
+- A character device.
+-
+- `DT_BLK'
+- A block device.
+-
+- This member is a BSD extension. The symbol
+- `_DIRENT_HAVE_D_TYPE' is defined if this member is available.
+- On systems where it is used, it corresponds to the file type
+- bits in the `st_mode' member of `struct statbuf'. If the
+- value cannot be determine the member value is DT_UNKNOWN.
+- These two macros convert between `d_type' values and
+- `st_mode' values:
+-
+- - Function: int IFTODT (mode_t MODE)
+- This returns the `d_type' value corresponding to MODE.
+-
+- - Function: mode_t DTTOIF (int DTYPE)
+- This returns the `st_mode' value corresponding to DTYPE.
+-
+- This structure may contain additional members in the future. Their
+- availability is always announced in the compilation environment by
+- a macro names `_DIRENT_HAVE_D_XXX' where XXX is replaced by the
+- name of the new member. For instance, the member `d_reclen'
+- available on some systems is announced through the macro
+- `_DIRENT_HAVE_D_RECLEN'.
+-
+- When a file has multiple names, each name has its own directory
+- entry. The only way you can tell that the directory entries
+- belong to a single file is that they have the same value for the
+- `d_fileno' field.
+-
+- File attributes such as size, modification times etc., are part of
+- the file itself, not of any particular directory entry. *Note
+- File Attributes::.

+-
+-Opening a Directory Stream
+---------------------------
+-
+- This section describes how to open a directory stream. All the
+-symbols are declared in the header file `dirent.h'.
+-
+- - Data Type: DIR
+- The `DIR' data type represents a directory stream.
+-
+- You shouldn't ever allocate objects of the `struct dirent' or `DIR'
+-data types, since the directory access functions do that for you.
+-Instead, you refer to these objects using the pointers returned by the
+-following functions.
+-
+- - Function: DIR * opendir (const char *DIRNAME)
+- The `opendir' function opens and returns a directory stream for
+- reading the directory whose file name is DIRNAME. The stream has
+- type `DIR *'.
+-
+- If unsuccessful, `opendir' returns a null pointer. In addition to
+- the usual file name errors (*note File Name Errors::), the
+- following `errno' error conditions are defined for this function:
+-
+- `EACCES'
+- Read permission is denied for the directory named by
+- `dirname'.
+-
+- `EMFILE'
+- The process has too many files open.
+-
+- `ENFILE'
+- The entire system, or perhaps the file system which contains
+- the directory, cannot support any additional open files at
+- the moment. (This problem cannot happen on the GNU system.)
+-
+- The `DIR' type is typically implemented using a file descriptor,
+- and the `opendir' function in terms of the `open' function. *Note
+- Low-Level I/O::. Directory streams and the underlying file
+- descriptors are closed on `exec' (*note Executing a File::).
+-
+- In some situations it can be desirable to get hold of the file
+-descriptor which is created by the `opendir' call. For instance, to
+-switch the current working directory to the directory just read the
+-`fchdir' function could be used. Historically the `DIR' type was
+-exposed and programs could access the fields. This does not happen in
+-the GNU C library. Instead a separate function is provided to allow
+-access.
+-
+- - Function: int dirfd (DIR *DIRSTREAM)
+- The function `dirfd' returns the file descriptor associated with
+- the directory stream DIRSTREAM. This descriptor can be used until
+- the directory is closed with `closedir'. If the directory stream
+- implementation is not using file descriptors the return value is
+- `-1'.

+-
+-Reading and Closing a Directory Stream
+---------------------------------------
+-
+- This section describes how to read directory entries from a directory
+-stream, and how to close the stream when you are done with it. All the
+-symbols are declared in the header file `dirent.h'.
+-
+- - Function: struct dirent * readdir (DIR *DIRSTREAM)
+- This function reads the next entry from the directory. It normally
+- returns a pointer to a structure containing information about the
+- file. This structure is statically allocated and can be rewritten
+- by a subsequent call.
+-
+- *Portability Note:* On some systems `readdir' may not return
+- entries for `.' and `..', even though these are always valid file
+- names in any directory. *Note File Name Resolution::.
+-
+- If there are no more entries in the directory or an error is
+- detected, `readdir' returns a null pointer. The following `errno'
+- error conditions are defined for this function:
+-
+- `EBADF'
+- The DIRSTREAM argument is not valid.
+-
+- `readdir' is not thread safe. Multiple threads using `readdir' on
+- the same DIRSTREAM may overwrite the return value. Use
+- `readdir_r' when this is critical.
+-
+- - Function: int readdir_r (DIR *DIRSTREAM, struct dirent *ENTRY,
+- struct dirent **RESULT)
+- This function is the reentrant version of `readdir'. Like
+- `readdir' it returns the next entry from the directory. But to
+- prevent conflicts between simultaneously running threads the
+- result is not stored in statically allocated memory. Instead the
+- argument ENTRY points to a place to store the result.
+-
+- Normally `readdir_r' returns zero and sets `*RESULT' to ENTRY. If
+- there are no more entries in the directory or an error is
+- detected, `readdir_r' sets `*RESULT' to a null pointer and returns
+- a nonzero error code, also stored in `errno', as described for
+- `readdir'.
+-
+- *Portability Note:* On some systems `readdir_r' may not return a
+- NUL terminated string for the file name, even when there is no
+- `d_reclen' field in `struct dirent' and the file name is the
+- maximum allowed size. Modern systems all have the `d_reclen'
+- field, and on old systems multi-threading is not critical. In any
+- case there is no such problem with the `readdir' function, so that
+- even on systems without the `d_reclen' member one could use
+- multiple threads by using external locking.
+-
+- It is also important to look at the definition of the `struct
+- dirent' type. Simply passing a pointer to an object of this type
+- for the second parameter of `readdir_r' might not be enough. Some
+- systems don't define the `d_name' element sufficiently long. In
+- this case the user has to provide additional space. There must be
+- room for at least `NAME_MAX + 1' characters in the `d_name' array.
+- Code to call `readdir_r' could look like this:
+-
+- union
+- {
+- struct dirent d;
+- char b[offsetof (struct dirent, d_name) + NAME_MAX + 1];
+- } u;
+-
+- if (readdir_r (dir, &u.d, &res) == 0)
+- ...
+-
+- To support large filesystems on 32-bit machines there are LFS
+-variants of the last two functions.
+-
+- - Function: struct dirent64 * readdir64 (DIR *DIRSTREAM)
+- The `readdir64' function is just like the `readdir' function
+- except that it returns a pointer to a record of type `struct
+- dirent64'. Some of the members of this data type (notably `d_ino')
+- might have a different size to allow large filesystems.
+-
+- In all other aspects this function is equivalent to `readdir'.
+-
+- - Function: int readdir64_r (DIR *DIRSTREAM, struct dirent64 *ENTRY,
+- struct dirent64 **RESULT)
+- The `readdir64_r' function is equivalent to the `readdir_r'
+- function except that it takes parameters of base type `struct
+- dirent64' instead of `struct dirent' in the second and third
+- position. The same precautions mentioned in the documentation of
+- `readdir_r' also apply here.
+-
+- - Function: int closedir (DIR *DIRSTREAM)
+- This function closes the directory stream DIRSTREAM. It returns
+- `0' on success and `-1' on failure.
+-
+- The following `errno' error conditions are defined for this
+- function:
+-
+- `EBADF'
+- The DIRSTREAM argument is not valid.

+-Simple Program to List a Directory
+-----------------------------------
+-
+- Here's a simple program that prints the names of the files in the
+-current working directory:
+-
+- #include <stdio.h>
+- #include <sys/types.h>
+- #include <dirent.h>
+-
+- int
+- main (void)
+- {
+- DIR *dp;
+- struct dirent *ep;

+- dp = opendir ("./");

+- puts (ep->d_name);
+- (void) closedir (dp);
+- }
+- else
+- perror ("Couldn't open the directory");
+-
+- return 0;
+- }
+-
+- The order in which files appear in a directory tends to be fairly
+-random. A more useful program would sort the entries (perhaps by
+-alphabetizing them) before printing them; see *Note Scanning Directory
+-Content::, and *Note Array Sort Function::.

+-
+-Random Access in a Directory Stream
+------------------------------------
+-
+- This section describes how to reread parts of a directory that you
+-have already read from an open directory stream. All the symbols are
+-declared in the header file `dirent.h'.
+-
+- - Function: void rewinddir (DIR *DIRSTREAM)
+- The `rewinddir' function is used to reinitialize the directory
+- stream DIRSTREAM, so that if you call `readdir' it returns
+- information about the first entry in the directory again. This
+- function also notices if files have been added or removed to the
+- directory since it was opened with `opendir'. (Entries for these
+- files might or might not be returned by `readdir' if they were
+- added or removed since you last called `opendir' or `rewinddir'.)
+-
+- - Function: off_t telldir (DIR *DIRSTREAM)
+- The `telldir' function returns the file position of the directory
+- stream DIRSTREAM. You can use this value with `seekdir' to
+- restore the directory stream to that position.
+-
+- - Function: void seekdir (DIR *DIRSTREAM, off_t POS)
+- The `seekdir' function sets the file position of the directory
+- stream DIRSTREAM to POS. The value POS must be the result of a
+- previous call to `telldir' on this particular stream; closing and
+- reopening the directory can invalidate values returned by
+- `telldir'.

+-File: libc.info, Node: Scanning Directory Content, Next: Simple Directory Lister Mark II, Prev: Random Access Directory, Up: Accessing Directories
+-
+-Scanning the Content of a Directory
+------------------------------------
+-
+- A higher-level interface to the directory handling functions is the
+-`scandir' function. With its help one can select a subset of the
+-entries in a directory, possibly sort them and get a list of names as
+-the result.
+-
+- - Function: int scandir (const char *DIR, struct dirent ***NAMELIST,
+- int (*SELECTOR) (const struct dirent *), int (*CMP) (const
+- void *, const void *))
+- The `scandir' function scans the contents of the directory selected
+- by DIR. The result in *NAMELIST is an array of pointers to
+- structure of type `struct dirent' which describe all selected
+- directory entries and which is allocated using `malloc'. Instead
+- of always getting all directory entries returned, the user supplied
+- function SELECTOR can be used to decide which entries are in the
+- result. Only the entries for which SELECTOR returns a non-zero
+- value are selected.
+-
+- Finally the entries in *NAMELIST are sorted using the
+- user-supplied function CMP. The arguments passed to the CMP
+- function are of type `struct dirent **', therefore one cannot
+- directly use the `strcmp' or `strcoll' functions; instead see the
+- functions `alphasort' and `versionsort' below.
+-
+- The return value of the function is the number of entries placed in
+- *NAMELIST. If it is `-1' an error occurred (either the directory
+- could not be opened for reading or the malloc call failed) and the
+- global variable `errno' contains more information on the error.
+-
+- As described above the fourth argument to the `scandir' function
+-must be a pointer to a sorting function. For the convenience of the
+-programmer the GNU C library contains implementations of functions which
+-are very helpful for this purpose.
+-
+- - Function: int alphasort (const void *A, const void *B)
+- The `alphasort' function behaves like the `strcoll' function
+- (*note String/Array Comparison::). The difference is that the
+- arguments are not string pointers but instead they are of type
+- `struct dirent **'.
+-
+- The return value of `alphasort' is less than, equal to, or greater
+- than zero depending on the order of the two entries A and B.
+-
+- - Function: int versionsort (const void *A, const void *B)
+- The `versionsort' function is like `alphasort' except that it uses
+- the `strverscmp' function internally.
+-
+- If the filesystem supports large files we cannot use the `scandir'
+-anymore since the `dirent' structure might not able to contain all the
+-information. The LFS provides the new type `struct dirent64'. To use
+-this we need a new function.
+-
+- - Function: int scandir64 (const char *DIR, struct dirent64
+- ***NAMELIST, int (*SELECTOR) (const struct dirent64 *), int
+- (*CMP) (const void *, const void *))
+- The `scandir64' function works like the `scandir' function except
+- that the directory entries it returns are described by elements of
+- type `struct dirent64'. The function pointed to by SELECTOR is
+- again used to select the desired entries, except that SELECTOR now
+- must point to a function which takes a `struct dirent64 *'
+- parameter.
+-
+- Similarly the CMP function should expect its two arguments to be
+- of type `struct dirent64 **'.
+-
+- As CMP is now a function of a different type, the functions
+-`alphasort' and `versionsort' cannot be supplied for that argument.
+-Instead we provide the two replacement functions below.
+-
+- - Function: int alphasort64 (const void *A, const void *B)
+- The `alphasort64' function behaves like the `strcoll' function
+- (*note String/Array Comparison::). The difference is that the
+- arguments are not string pointers but instead they are of type
+- `struct dirent64 **'.
+-
+- Return value of `alphasort64' is less than, equal to, or greater
+- than zero depending on the order of the two entries A and B.
+-
+- - Function: int versionsort64 (const void *A, const void *B)
+- The `versionsort64' function is like `alphasort64', excepted that
+- it uses the `strverscmp' function internally.
+-
+- It is important not to mix the use of `scandir' and the 64-bit
+-comparison functions or vice versa. There are systems on which this
+-works but on others it will fail miserably.

+-Working with Directory Trees
+-============================
+-
+- The functions described so far for handling the files in a directory
+-have allowed you to either retrieve the information bit by bit, or to
+-process all the files as a group (see `scandir'). Sometimes it is
+-useful to process whole hierarchies of directories and their contained
+-files. The X/Open specification defines two functions to do this. The
+-simpler form is derived from an early definition in System V systems
+-and therefore this function is available on SVID-derived systems. The
+-prototypes and required definitions can be found in the `ftw.h' header.
+-
+- There are four functions in this family: `ftw', `nftw' and their
+-64-bit counterparts `ftw64' and `nftw64'. These functions take as one
+-of their arguments a pointer to a callback function of the appropriate
+-type.
+-
+- - Data Type: __ftw_func_t
+- int (*) (const char *, const struct stat *, int)
+-
+- The type of callback functions given to the `ftw' function. The
+- first parameter points to the file name, the second parameter to an
+- object of type `struct stat' which is filled in for the file named
+- in the first parameter.
+-
+- The last parameter is a flag giving more information about the
+- current file. It can have the following values:
+-
+- `FTW_F'
+- The item is either a normal file or a file which does not fit
+- into one of the following categories. This could be special
+- files, sockets etc.
+-
+- `FTW_D'
+- The item is a directory.
+-
+- `FTW_NS'
+- The `stat' call failed and so the information pointed to by
+- the second paramater is invalid.
+-
+- `FTW_DNR'
+- The item is a directory which cannot be read.
+-
+- `FTW_SL'
+- The item is a symbolic link. Since symbolic links are
+- normally followed seeing this value in a `ftw' callback
+- function means the referenced file does not exist. The
+- situation for `nftw' is different.
+-
+- This value is only available if the program is compiled with
+- `_BSD_SOURCE' or `_XOPEN_EXTENDED' defined before including
+- the first header. The original SVID systems do not have
+- symbolic links.
+-
+- If the sources are compiled with `_FILE_OFFSET_BITS == 64' this
+- type is in fact `__ftw64_func_t' since this mode changes `struct
+- stat' to be `struct stat64'.
+-
+- For the LFS interface and for use in the function `ftw64', the
+-header `ftw.h' defines another function type.
+-
+- - Data Type: __ftw64_func_t
+- int (*) (const char *, const struct stat64 *, int)
+-
+- This type is used just like `__ftw_func_t' for the callback
+- function, but this time is called from `ftw64'. The second
+- parameter to the function is a pointer to a variable of type
+- `struct stat64' which is able to represent the larger values.
+-
+- - Data Type: __nftw_func_t
+- int (*) (const char *, const struct stat *, int, struct FTW *)
+-
+- The first three arguments are the same as for the `__ftw_func_t'
+- type. However for the third argument some additional values are
+- defined to allow finer differentiation:
+- `FTW_DP'
+- The current item is a directory and all subdirectories have
+- already been visited and reported. This flag is returned
+- instead of `FTW_D' if the `FTW_DEPTH' flag is passed to
+- `nftw' (see below).
+-
+- `FTW_SLN'
+- The current item is a stale symbolic link. The file it
+- points to does not exist.
+-
+- The last parameter of the callback function is a pointer to a
+- structure with some extra information as described below.
+-
+- If the sources are compiled with `_FILE_OFFSET_BITS == 64' this
+- type is in fact `__nftw64_func_t' since this mode changes `struct
+- stat' to be `struct stat64'.
+-
+- For the LFS interface there is also a variant of this data type
+-available which has to be used with the `nftw64' function.
+-
+- - Data Type: __nftw64_func_t
+- int (*) (const char *, const struct stat64 *, int, struct FTW *)
+-
+- This type is used just like `__nftw_func_t' for the callback
+- function, but this time is called from `nftw64'. The second
+- parameter to the function is this time a pointer to a variable of
+- type `struct stat64' which is able to represent the larger values.
+-
+- - Data Type: struct FTW
+- The information contained in this structure helps in interpreting
+- the name parameter and gives some information about the current
+- state of the traversal of the directory hierarchy.
+-
+- `int base'
+- The value is the offset into the string passed in the first
+- parameter to the callback function of the beginning of the
+- file name. The rest of the string is the path of the file.
+- This information is especially important if the `FTW_CHDIR'
+- flag was set in calling `nftw' since then the current
+- directory is the one the current item is found in.
+-
+- `int level'
+- Whilst processing, the code tracks how many directories down
+- it has gone to find the current file. This nesting level
+- starts at 0 for files in the initial directory (or is zero
+- for the initial file if a file was passed).
+-
+- - Function: int ftw (const char *FILENAME, __ftw_func_t FUNC, int
+- DESCRIPTORS)
+- The `ftw' function calls the callback function given in the
+- parameter FUNC for every item which is found in the directory
+- specified by FILENAME and all directories below. The function
+- follows symbolic links if necessary but does not process an item
+- twice. If FILENAME is not a directory then it itself is the only
+- object returned to the callback function.
+-
+- The file name passed to the callback function is constructed by
+- taking the FILENAME parameter and appending the names of all passed
+- directories and then the local file name. So the callback
+- function can use this parameter to access the file. `ftw' also
+- calls `stat' for the file and passes that information on to the
+- callback function. If this `stat' call was not successful the
+- failure is indicated by setting the third argument of the callback
+- function to `FTW_NS'. Otherwise it is set according to the
+- description given in the account of `__ftw_func_t' above.
+-
+- The callback function is expected to return 0 to indicate that no
+- error occurred and that processing should continue. If an error
+- occurred in the callback function or it wants `ftw' to return
+- immediately, the callback function can return a value other than
+- 0. This is the only correct way to stop the function. The
+- program must not use `setjmp' or similar techniques to continue
+- from another place. This would leave resources allocated by the
+- `ftw' function unfreed.
+-
+- The DESCRIPTORS parameter to `ftw' specifies how many file
+- descriptors it is allowed to consume. The function runs faster
+- the more descriptors it can use. For each level in the directory
+- hierarchy at most one descriptor is used, but for very deep ones
+- any limit on open file descriptors for the process or the system
+- may be exceeded. Moreover, file descriptor limits in a
+- multi-threaded program apply to all the threads as a group, and
+- therefore it is a good idea to supply a reasonable limit to the
+- number of open descriptors.
+-
+- The return value of the `ftw' function is 0 if all callback
+- function calls returned 0 and all actions performed by the `ftw'
+- succeeded. If a function call failed (other than calling `stat'
+- on an item) the function returns -1. If a callback function
+- returns a value other than 0 this value is returned as the return
+- value of `ftw'.
+-
+- When the sources are compiled with `_FILE_OFFSET_BITS == 64' on a
+- 32-bit system this function is in fact `ftw64', i.e. the LFS
+- interface transparently replaces the old interface.
+-
+- - Function: int ftw64 (const char *FILENAME, __ftw64_func_t FUNC, int
+- DESCRIPTORS)
+- This function is similar to `ftw' but it can work on filesystems
+- with large files. File information is reported using a variable
+- of type `struct stat64' which is passed by reference to the
+- callback function.
+-
+- When the sources are compiled with `_FILE_OFFSET_BITS == 64' on a
+- 32-bit system this function is available under the name `ftw' and
+- transparently replaces the old implementation.
+-
+- - Function: int nftw (const char *FILENAME, __nftw_func_t FUNC, int
+- DESCRIPTORS, int FLAG)
+- The `nftw' function works like the `ftw' functions. They call the
+- callback function FUNC for all items found in the directory
+- FILENAME and below. At most DESCRIPTORS file descriptors are
+- consumed during the `nftw' call.
+-
+- One difference is that the callback function is of a different
+- type. It is of type `struct FTW *' and provides the callback
+- function with the extra information described above.
+-
+- A second difference is that `nftw' takes a fourth argument, which
+- is 0 or a bitwise-OR combination of any of the following values.
+-
+- `FTW_PHYS'
+- While traversing the directory symbolic links are not
+- followed. Instead symbolic links are reported using the
+- `FTW_SL' value for the type parameter to the callback
+- function. If the file referenced by a symbolic link does not
+- exist `FTW_SLN' is returned instead.
+-
+- `FTW_MOUNT'
+- The callback function is only called for items which are on
+- the same mounted filesystem as the directory given by the
+- FILENAME parameter to `nftw'.
+-
+- `FTW_CHDIR'
+- If this flag is given the current working directory is
+- changed to the directory of the reported object before the
+- callback function is called. When `ntfw' finally returns the
+- current directory is restored to its original value.
+-
+- `FTW_DEPTH'
+- If this option is specified then all subdirectories and files
+- within them are processed before processing the top directory
+- itself (depth-first processing). This also means the type
+- flag given to the callback function is `FTW_DP' and not
+- `FTW_D'.
+-
+- The return value is computed in the same way as for `ftw'. `nftw'
+- returns 0 if no failures occurred and all callback functions
+- returned 0. In case of internal errors, such as memory problems,
+- the return value is -1 and ERRNO is set accordingly. If the
+- return value of a callback invocation was non-zero then that value
+- is returned.
+-
+- When the sources are compiled with `_FILE_OFFSET_BITS == 64' on a
+- 32-bit system this function is in fact `nftw64', i.e. the LFS
+- interface transparently replaces the old interface.
+-
+- - Function: int nftw64 (const char *FILENAME, __nftw64_func_t FUNC,
+- int DESCRIPTORS, int FLAG)
+- This function is similar to `nftw' but it can work on filesystems
+- with large files. File information is reported using a variable
+- of type `struct stat64' which is passed by reference to the
+- callback function.
+-
+- When the sources are compiled with `_FILE_OFFSET_BITS == 64' on a
+- 32-bit system this function is available under the name `nftw' and
+- transparently replaces the old implementation.

+-
+-Hard Links
+-==========
+-
+- In POSIX systems, one file can have many names at the same time.
+-All of the names are equally real, and no one of them is preferred to
+-the others.
+-
+- To add a name to a file, use the `link' function. (The new name is
+-also called a "hard link" to the file.) Creating a new link to a file
+-does not copy the contents of the file; it simply makes a new name by
+-which the file can be known, in addition to the file's existing name or
+-names.
+-
+- One file can have names in several directories, so the organization
+-of the file system is not a strict hierarchy or tree.
+-
+- In most implementations, it is not possible to have hard links to the
+-same file in multiple file systems. `link' reports an error if you try
+-to make a hard link to the file from another file system when this
+-cannot be done.
+-
+- The prototype for the `link' function is declared in the header file
+-`unistd.h'.
+-
+- - Function: int link (const char *OLDNAME, const char *NEWNAME)
+- The `link' function makes a new link to the existing file named by
+- OLDNAME, under the new name NEWNAME.
+-
+- This function returns a value of `0' if it is successful and `-1'
+- on failure. In addition to the usual file name errors (*note File
+- Name Errors::) for both OLDNAME and NEWNAME, the following `errno'
+- error conditions are defined for this function:
+-
+- `EACCES'
+- You are not allowed to write to the directory in which the
+- new link is to be written.
+-
+- `EEXIST'
+- There is already a file named NEWNAME. If you want to replace
+- this link with a new link, you must remove the old link
+- explicitly first.
+-
+- `EMLINK'
+- There are already too many links to the file named by OLDNAME.
+- (The maximum number of links to a file is `LINK_MAX'; see
+- *Note Limits for Files::.)
+-
+- `ENOENT'
+- The file named by OLDNAME doesn't exist. You can't make a
+- link to a file that doesn't exist.
+-
+- `ENOSPC'
+- The directory or file system that would contain the new link
+- is full and cannot be extended.
+-
+- `EPERM'
+- In the GNU system and some others, you cannot make links to
+- directories. Many systems allow only privileged users to do
+- so. This error is used to report the problem.
+-
+- `EROFS'
+- The directory containing the new link can't be modified
+- because it's on a read-only file system.
+-
+- `EXDEV'
+- The directory specified in NEWNAME is on a different file
+- system than the existing file.
+-
+- `EIO'
+- A hardware error occurred while trying to read or write the
+- to filesystem.

+-File: libc.info, Node: Symbolic Links, Next: Deleting Files, Prev: Hard Links, Up: File System Interface
+-
+-Symbolic Links
+-==============
+-
+- The GNU system supports "soft links" or "symbolic links". This is a
+-kind of "file" that is essentially a pointer to another file name.
+-Unlike hard links, symbolic links can be made to directories or across
+-file systems with no restrictions. You can also make a symbolic link
+-to a name which is not the name of any file. (Opening this link will
+-fail until a file by that name is created.) Likewise, if the symbolic
+-link points to an existing file which is later deleted, the symbolic
+-link continues to point to the same file name even though the name no
+-longer names any file.
+-
+- The reason symbolic links work the way they do is that special things
+-happen when you try to open the link. The `open' function realizes you
+-have specified the name of a link, reads the file name contained in the
+-link, and opens that file name instead. The `stat' function likewise
+-operates on the file that the symbolic link points to, instead of on
+-the link itself.
+-
+- By contrast, other operations such as deleting or renaming the file
+-operate on the link itself. The functions `readlink' and `lstat' also
+-refrain from following symbolic links, because their purpose is to
+-obtain information about the link. `link', the function that makes a
+-hard link, does too. It makes a hard link to the symbolic link, which
+-one rarely wants.
+-
+- Some systems have for some functions operating on files have a limit
+-on how many symbolic links are followed when resolving a path name. The
+-limit if it exists is published in the `sys/param.h' header file.
+-
+- - Macro: int MAXSYMLINKS
+- The macro `MAXSYMLINKS' specifies how many symlinks some function
+- will follow before returning `ELOOP'. Not all functions behave the
+- same and this value is not the same a that returned for
+- `_SC_SYMLOOP' by `sysconf'. In fact, the `sysconf' result can
+- indicate that there is no fixed limit although `MAXSYMLINKS'
+- exists and has a finite value.
+-
+- Prototypes for most of the functions listed in this section are in
+-`unistd.h'.
+-
+- - Function: int symlink (const char *OLDNAME, const char *NEWNAME)
+- The `symlink' function makes a symbolic link to OLDNAME named
+- NEWNAME.
+-
+- The normal return value from `symlink' is `0'. A return value of
+- `-1' indicates an error. In addition to the usual file name
+- syntax errors (*note File Name Errors::), the following `errno'
+- error conditions are defined for this function:
+-
+- `EEXIST'
+- There is already an existing file named NEWNAME.
+-
+- `EROFS'
+- The file NEWNAME would exist on a read-only file system.
+-
+- `ENOSPC'
+- The directory or file system cannot be extended to make the
+- new link.
+-
+- `EIO'
+- A hardware error occurred while reading or writing data on
+- the disk.
+-
+-
+- - Function: int readlink (const char *FILENAME, char *BUFFER, size_t
+- SIZE)
+- The `readlink' function gets the value of the symbolic link
+- FILENAME. The file name that the link points to is copied into
+- BUFFER. This file name string is _not_ null-terminated;
+- `readlink' normally returns the number of characters copied. The
+- SIZE argument specifies the maximum number of characters to copy,
+- usually the allocation size of BUFFER.
+-
+- If the return value equals SIZE, you cannot tell whether or not
+- there was room to return the entire name. So make a bigger buffer
+- and call `readlink' again. Here is an example:
+-
+- char *
+- readlink_malloc (const char *filename)
+- {
+- int size = 100;
+- char *buffer = NULL;
+-
+- while (1)
+- {
+- buffer = (char *) xrealloc (buffer, size);
+- int nchars = readlink (filename, buffer, size);
+- if (nchars < 0)
+- {
+- free (buffer);
+- return NULL;
+- }
+- if (nchars < size)
+- return buffer;
+- size *= 2;
+- }
+- }
+-
+- A value of `-1' is returned in case of error. In addition to the
+- usual file name errors (*note File Name Errors::), the following
+- `errno' error conditions are defined for this function:
+-
+- `EINVAL'
+- The named file is not a symbolic link.
+-
+- `EIO'
+- A hardware error occurred while reading or writing data on
+- the disk.
+-
+- In some situations it is desirable to resolve all the symbolic links
+-to get the real name of a file where no prefix names a symbolic link
+-which is followed and no filename in the path is `.' or `..'. This is
+-for instance desirable if files have to be compare in which case
+-different names can refer to the same inode.
+-
+- - Function: char * canonicalize_file_name (const char *NAME)
+- The `canonicalize_file_name' function returns the absolute name of
+- the file named by NAME which contains no `.', `..' components nor
+- any repeated path separators (`/') or symlinks. The result is
+- passed back as the return value of the function in a block of
+- memory allocated with `malloc'. If the result is not used anymore
+- the memory should be freed with a call to `free'.
+-
+- In any of the path components except the last one is missing the
+- function returns a NULL pointer. This is also what is returned if
+- the length of the path reaches or exceeds `PATH_MAX' characters.
+- In any case `errno' is set accordingly.
+-
+- `ENAMETOOLONG'
+- The resulting path is too long. This error only occurs on
+- systems which have a limit on the file name length.
+-
+- `EACCES'
+- At least one of the path components is not readable.
+-
+- `ENOENT'
+- The input file name is empty.
+-
+- `ENOENT'
+- At least one of the path components does not exist.
+-
+- `ELOOP'
+- More than `MAXSYMLINKS' many symlinks have been followed.
+-
+- This function is a GNU extension and is declared in `stdlib.h'.
+-
+- The Unix standard includes a similar function which differs from
+-`canonicalize_file_name' in that the user has to provide the buffer
+-where the result is placed in.
+-
+- - Function: char * realpath (const char *restrict NAME, char *restrict
+- RESOLVED)
+- A call to `realpath' where the RESOLVED parameter is `NULL'
+- behaves exactly like `canonicalize_file_name'. The function
+- allocates a buffer for the file name and returns a pointer to it.
+- If RESOLVED is not `NULL' it points to a buffer into which the
+- result is copied. It is the callers responsibility to allocate a
+- buffer which is large enough. On systems which define `PATH_MAX'
+- this means the buffer must be large enough for a pathname of this
+- size. For systems without limitations on the pathname length the
+- requirement cannot be met and programs should not call `realpath'
+- with anything but `NULL' for the second parameter.
+-
+- One other difference is that the buffer RESOLVED (if nonzero) will
+- contain the part of the path component which does not exist or is
+- not readable if the function returns `NULL' and `errno' is set to
+- `EACCES' or `ENOENT'.
+-
+- This function is declared in `stdlib.h'.
+-
+- The advantage of using this function is that it is more widely
+-available. The drawback is that it reports failures for long path on
+-systems which have no limits on the file name length.

+-Deleting Files
+-==============
+-
+- You can delete a file with `unlink' or `remove'.
+-
+- Deletion actually deletes a file name. If this is the file's only
+-name, then the file is deleted as well. If the file has other
+-remaining names (*note Hard Links::), it remains accessible under those
+-names.
+-
+- - Function: int unlink (const char *FILENAME)
+- The `unlink' function deletes the file name FILENAME. If this is
+- a file's sole name, the file itself is also deleted. (Actually,
+- if any process has the file open when this happens, deletion is
+- postponed until all processes have closed the file.)
+-
+- The function `unlink' is declared in the header file `unistd.h'.
+-
+- This function returns `0' on successful completion, and `-1' on
+- error. In addition to the usual file name errors (*note File Name
+- Errors::), the following `errno' error conditions are defined for
+- this function:
+-
+- `EACCES'
+- Write permission is denied for the directory from which the
+- file is to be removed, or the directory has the sticky bit
+- set and you do not own the file.
+-
+- `EBUSY'
+- This error indicates that the file is being used by the
+- system in such a way that it can't be unlinked. For example,
+- you might see this error if the file name specifies the root
+- directory or a mount point for a file system.
+-
+- `ENOENT'
+- The file name to be deleted doesn't exist.
+-
+- `EPERM'
+- On some systems `unlink' cannot be used to delete the name of
+- a directory, or at least can only be used this way by a
+- privileged user. To avoid such problems, use `rmdir' to
+- delete directories. (In the GNU system `unlink' can never
+- delete the name of a directory.)
+-
+- `EROFS'
+- The directory containing the file name to be deleted is on a
+- read-only file system and can't be modified.
+-
+- - Function: int rmdir (const char *FILENAME)
+- The `rmdir' function deletes a directory. The directory must be
+- empty before it can be removed; in other words, it can only contain
+- entries for `.' and `..'.
+-
+- In most other respects, `rmdir' behaves like `unlink'. There are
+- two additional `errno' error conditions defined for `rmdir':
+-
+- `ENOTEMPTY'
+- `EEXIST'
+- The directory to be deleted is not empty.
+-
+- These two error codes are synonymous; some systems use one, and
+- some use the other. The GNU system always uses `ENOTEMPTY'.
+-
+- The prototype for this function is declared in the header file
+- `unistd.h'.
+-
+- - Function: int remove (const char *FILENAME)
+- This is the ISO C function to remove a file. It works like
+- `unlink' for files and like `rmdir' for directories. `remove' is
+- declared in `stdio.h'.

+-File: libc.info, Node: Renaming Files, Next: Creating Directories, Prev: Deleting Files, Up: File System Interface
+-
+-Renaming Files
+-==============
+-
+- The `rename' function is used to change a file's name.
+-
+- - Function: int rename (const char *OLDNAME, const char *NEWNAME)
+- The `rename' function renames the file OLDNAME to NEWNAME. The
+- file formerly accessible under the name OLDNAME is afterwards
+- accessible as NEWNAME instead. (If the file had any other names
+- aside from OLDNAME, it continues to have those names.)
+-
+- The directory containing the name NEWNAME must be on the same file
+- system as the directory containing the name OLDNAME.
+-
+- One special case for `rename' is when OLDNAME and NEWNAME are two
+- names for the same file. The consistent way to handle this case
+- is to delete OLDNAME. However, in this case POSIX requires that
+- `rename' do nothing and report success--which is inconsistent. We
+- don't know what your operating system will do.
+-
+- If OLDNAME is not a directory, then any existing file named
+- NEWNAME is removed during the renaming operation. However, if
+- NEWNAME is the name of a directory, `rename' fails in this case.
+-
+- If OLDNAME is a directory, then either NEWNAME must not exist or
+- it must name a directory that is empty. In the latter case, the
+- existing directory named NEWNAME is deleted first. The name
+- NEWNAME must not specify a subdirectory of the directory `oldname'
+- which is being renamed.
+-
+- One useful feature of `rename' is that the meaning of NEWNAME
+- changes "atomically" from any previously existing file by that
+- name to its new meaning (i.e. the file that was called OLDNAME).
+- There is no instant at which NEWNAME is non-existent "in between"
+- the old meaning and the new meaning. If there is a system crash
+- during the operation, it is possible for both names to still
+- exist; but NEWNAME will always be intact if it exists at all.
+-
+- If `rename' fails, it returns `-1'. In addition to the usual file
+- name errors (*note File Name Errors::), the following `errno'
+- error conditions are defined for this function:
+-
+- `EACCES'
+- One of the directories containing NEWNAME or OLDNAME refuses
+- write permission; or NEWNAME and OLDNAME are directories and
+- write permission is refused for one of them.
+-
+- `EBUSY'
+- A directory named by OLDNAME or NEWNAME is being used by the
+- system in a way that prevents the renaming from working.
+- This includes directories that are mount points for
+- filesystems, and directories that are the current working
+- directories of processes.
+-
+- `ENOTEMPTY'
+- `EEXIST'
+- The directory NEWNAME isn't empty. The GNU system always
+- returns `ENOTEMPTY' for this, but some other systems return
+- `EEXIST'.
+-
+- `EINVAL'
+- OLDNAME is a directory that contains NEWNAME.
+-
+- `EISDIR'
+- NEWNAME is a directory but the OLDNAME isn't.
+-
+- `EMLINK'
+- The parent directory of NEWNAME would have too many links
+- (entries).
+-
+- `ENOENT'
+- The file OLDNAME doesn't exist.
+-
+- `ENOSPC'
+- The directory that would contain NEWNAME has no room for
+- another entry, and there is no space left in the file system
+- to expand it.
+-
+- `EROFS'
+- The operation would involve writing to a directory on a
+- read-only file system.
+-
+- `EXDEV'
+- The two file names NEWNAME and OLDNAME are on different file
+- systems.

+-Creating Directories
+-====================
+-
+- Directories are created with the `mkdir' function. (There is also a
+-shell command `mkdir' which does the same thing.)
+-
+- - Function: int mkdir (const char *FILENAME, mode_t MODE)
+- The `mkdir' function creates a new, empty directory with name
+- FILENAME.
+-
+- The argument MODE specifies the file permissions for the new
+- directory file. *Note Permission Bits::, for more information
+- about this.
+-
+- A return value of `0' indicates successful completion, and `-1'
+- indicates failure. In addition to the usual file name syntax
+- errors (*note File Name Errors::), the following `errno' error
+- conditions are defined for this function:
+-
+- `EACCES'
+- Write permission is denied for the parent directory in which
+- the new directory is to be added.
+-
+- `EEXIST'
+- A file named FILENAME already exists.
+-
+- `EMLINK'
+- The parent directory has too many links (entries).
+-
+- Well-designed file systems never report this error, because
+- they permit more links than your disk could possibly hold.
+- However, you must still take account of the possibility of
+- this error, as it could result from network access to a file
+- system on another machine.
+-
+- `ENOSPC'
+- The file system doesn't have enough room to create the new
+- directory.
+-
+- `EROFS'
+- The parent directory of the directory being created is on a

+-The meaning of the File Attributes
+-----------------------------------
+-
+- When you read the attributes of a file, they come back in a structure

+-attributes, their data types, and what they mean. For the functions to
+-read the attributes of a file, see *Note Reading Attributes::.
+-
+- The header file `sys/stat.h' declares all the symbols defined in
+-this section.
+-
+- - Data Type: struct stat
+- The `stat' structure type is used to return information about the
+- attributes of a file. It contains at least the following members:
+-
+- `mode_t st_mode'
+- Specifies the mode of the file. This includes file type
+- information (*note Testing File Type::) and the file
+- permission bits (*note Permission Bits::).
+-
+- `ino_t st_ino'
+- The file serial number, which distinguishes this file from
+- all other files on the same device.
+-
+- `dev_t st_dev'
+- Identifies the device containing the file. The `st_ino' and
+- `st_dev', taken together, uniquely identify the file. The
+- `st_dev' value is not necessarily consistent across reboots or
+- system crashes, however.
+-
+- `nlink_t st_nlink'
+- The number of hard links to the file. This count keeps track
+- of how many directories have entries for this file. If the
+- count is ever decremented to zero, then the file itself is
+- discarded as soon as no process still holds it open.
+- Symbolic links are not counted in the total.
+-
+- `uid_t st_uid'
+- The user ID of the file's owner. *Note File Owner::.
+-
+- `gid_t st_gid'
+- The group ID of the file. *Note File Owner::.
+-
+- `off_t st_size'
+- This specifies the size of a regular file in bytes. For
+- files that are really devices this field isn't usually
+- meaningful. For symbolic links this specifies the length of
+- the file name the link refers to.
+-
+- `time_t st_atime'
+- This is the last access time for the file. *Note File
+- Times::.
+-
+- `unsigned long int st_atime_usec'
+- This is the fractional part of the last access time for the
+- file. *Note File Times::.
+-
+- `time_t st_mtime'
+- This is the time of the last modification to the contents of
+- the file. *Note File Times::.
+-
+- `unsigned long int st_mtime_usec'
+- This is the fractional part of the time of the last
+- modification to the contents of the file. *Note File Times::.
+-
+- `time_t st_ctime'
+- This is the time of the last modification to the attributes
+- of the file. *Note File Times::.
+-
+- `unsigned long int st_ctime_usec'
+- This is the fractional part of the time of the last
+- modification to the attributes of the file. *Note File
+- Times::.
+-
+- `blkcnt_t st_blocks'
+- This is the amount of disk space that the file occupies,
+- measured in units of 512-byte blocks.
+-
+- The number of disk blocks is not strictly proportional to the
+- size of the file, for two reasons: the file system may use
+- some blocks for internal record keeping; and the file may be
+- sparse--it may have "holes" which contain zeros but do not
+- actually take up space on the disk.
+-
+- You can tell (approximately) whether a file is sparse by
+- comparing this value with `st_size', like this:
+-
+- (st.st_blocks * 512 < st.st_size)
+-
+- This test is not perfect because a file that is just slightly
+- sparse might not be detected as sparse at all. For practical
+- applications, this is not a problem.
+-
+- `unsigned int st_blksize'
+- The optimal block size for reading of writing this file, in
+- bytes. You might use this size for allocating the buffer
+- space for reading of writing the file. (This is unrelated to
+- `st_blocks'.)
+-
+- The extensions for the Large File Support (LFS) require, even on
+-32-bit machines, types which can handle file sizes up to 2^63.
+-Therefore a new definition of `struct stat' is necessary.
+-
+- - Data Type: struct stat64
+- The members of this type are the same and have the same names as
+- those in `struct stat'. The only difference is that the members
+- `st_ino', `st_size', and `st_blocks' have a different type to
+- support larger values.
+-
+- `mode_t st_mode'
+- Specifies the mode of the file. This includes file type
+- information (*note Testing File Type::) and the file
+- permission bits (*note Permission Bits::).
+-
+- `ino64_t st_ino'
+- The file serial number, which distinguishes this file from
+- all other files on the same device.
+-
+- `dev_t st_dev'
+- Identifies the device containing the file. The `st_ino' and
+- `st_dev', taken together, uniquely identify the file. The
+- `st_dev' value is not necessarily consistent across reboots or
+- system crashes, however.
+-
+- `nlink_t st_nlink'
+- The number of hard links to the file. This count keeps track
+- of how many directories have entries for this file. If the
+- count is ever decremented to zero, then the file itself is
+- discarded as soon as no process still holds it open.
+- Symbolic links are not counted in the total.
+-
+- `uid_t st_uid'
+- The user ID of the file's owner. *Note File Owner::.
+-
+- `gid_t st_gid'
+- The group ID of the file. *Note File Owner::.
+-
+- `off64_t st_size'
+- This specifies the size of a regular file in bytes. For
+- files that are really devices this field isn't usually
+- meaningful. For symbolic links this specifies the length of
+- the file name the link refers to.
+-
+- `time_t st_atime'
+- This is the last access time for the file. *Note File
+- Times::.
+-
+- `unsigned long int st_atime_usec'
+- This is the fractional part of the last access time for the
+- file. *Note File Times::.
+-
+- `time_t st_mtime'
+- This is the time of the last modification to the contents of
+- the file. *Note File Times::.
+-
+- `unsigned long int st_mtime_usec'
+- This is the fractional part of the time of the last
+- modification to the contents of the file. *Note File Times::.
+-
+- `time_t st_ctime'
+- This is the time of the last modification to the attributes
+- of the file. *Note File Times::.
+-
+- `unsigned long int st_ctime_usec'
+- This is the fractional part of the time of the last
+- modification to the attributes of the file. *Note File
+- Times::.
+-
+- `blkcnt64_t st_blocks'
+- This is the amount of disk space that the file occupies,
+- measured in units of 512-byte blocks.
+-
+- `unsigned int st_blksize'
+- The optimal block size for reading of writing this file, in
+- bytes. You might use this size for allocating the buffer
+- space for reading of writing the file. (This is unrelated to
+- `st_blocks'.)
+-
+- Some of the file attributes have special data type names which exist
+-specifically for those attributes. (They are all aliases for well-known
+-integer types that you know and love.) These typedef names are defined
+-in the header file `sys/types.h' as well as in `sys/stat.h'. Here is a
+-list of them.
+-
+- - Data Type: mode_t
+- This is an integer data type used to represent file modes. In the
+- GNU system, this is equivalent to `unsigned int'.
+-
+- - Data Type: ino_t
+- This is an arithmetic data type used to represent file serial
+- numbers. (In Unix jargon, these are sometimes called "inode
+- numbers".) In the GNU system, this type is equivalent to
+- `unsigned long int'.
+-
+- If the source is compiled with `_FILE_OFFSET_BITS == 64' this type
+- is transparently replaced by `ino64_t'.
+-
+- - Data Type: ino64_t
+- This is an arithmetic data type used to represent file serial
+- numbers for the use in LFS. In the GNU system, this type is
+- equivalent to `unsigned long longint'.
+-
+- When compiling with `_FILE_OFFSET_BITS == 64' this type is
+- available under the name `ino_t'.
+-
+- - Data Type: dev_t
+- This is an arithmetic data type used to represent file device
+- numbers. In the GNU system, this is equivalent to `int'.
+-
+- - Data Type: nlink_t
+- This is an arithmetic data type used to represent file link counts.
+- In the GNU system, this is equivalent to `unsigned short int'.
+-
+- - Data Type: blkcnt_t
+- This is an arithmetic data type used to represent block counts.
+- In the GNU system, this is equivalent to `unsigned long int'.
+-
+- If the source is compiled with `_FILE_OFFSET_BITS == 64' this type
+- is transparently replaced by `blkcnt64_t'.
+-
+- - Data Type: blkcnt64_t
+- This is an arithmetic data type used to represent block counts for
+- the use in LFS. In the GNU system, this is equivalent to `unsigned
+- long long int'.
+-
+- When compiling with `_FILE_OFFSET_BITS == 64' this type is
+- available under the name `blkcnt_t'.

+-
+-Reading the Attributes of a File
+---------------------------------
+-
+- To examine the attributes of files, use the functions `stat',
+-`fstat' and `lstat'. They return the attribute information in a
+-`struct stat' object. All three functions are declared in the header
+-file `sys/stat.h'.
+-
+- - Function: int stat (const char *FILENAME, struct stat *BUF)
+- The `stat' function returns information about the attributes of the
+- file named by FILENAME in the structure pointed to by BUF.
+-
+- If FILENAME is the name of a symbolic link, the attributes you get
+- describe the file that the link points to. If the link points to a
+- nonexistent file name, then `stat' fails reporting a nonexistent
+- file.
+-
+- The return value is `0' if the operation is successful, or `-1' on
+- failure. In addition to the usual file name errors (*note File
+- Name Errors::, the following `errno' error conditions are defined
+- for this function:
+-
+- `ENOENT'
+- The file named by FILENAME doesn't exist.
+-
+- When the sources are compiled with `_FILE_OFFSET_BITS == 64' this
+- function is in fact `stat64' since the LFS interface transparently
+- replaces the normal implementation.
+-
+- - Function: int stat64 (const char *FILENAME, struct stat64 *BUF)
+- This function is similar to `stat' but it is also able to work on
+- files larger then 2^31 bytes on 32-bit systems. To be able to do
+- this the result is stored in a variable of type `struct stat64' to
+- which BUF must point.
+-
+- When the sources are compiled with `_FILE_OFFSET_BITS == 64' this
+- function is available under the name `stat' and so transparently
+- replaces the interface for small files on 32-bit machines.
+-
+- - Function: int fstat (int FILEDES, struct stat *BUF)
+- The `fstat' function is like `stat', except that it takes an open
+- file descriptor as an argument instead of a file name. *Note
+- Low-Level I/O::.
+-
+- Like `stat', `fstat' returns `0' on success and `-1' on failure.
+- The following `errno' error conditions are defined for `fstat':
+-
+- `EBADF'
+- The FILEDES argument is not a valid file descriptor.
+-
+- When the sources are compiled with `_FILE_OFFSET_BITS == 64' this
+- function is in fact `fstat64' since the LFS interface transparently
+- replaces the normal implementation.
+-
+- - Function: int fstat64 (int FILEDES, struct stat64 *BUF)
+- This function is similar to `fstat' but is able to work on large
+- files on 32-bit platforms. For large files the file descriptor
+- FILEDES should be obtained by `open64' or `creat64'. The BUF
+- pointer points to a variable of type `struct stat64' which is able
+- to represent the larger values.
+-
+- When the sources are compiled with `_FILE_OFFSET_BITS == 64' this
+- function is available under the name `fstat' and so transparently
+- replaces the interface for small files on 32-bit machines.
+-
+- - Function: int lstat (const char *FILENAME, struct stat *BUF)
+- The `lstat' function is like `stat', except that it does not
+- follow symbolic links. If FILENAME is the name of a symbolic
+- link, `lstat' returns information about the link itself; otherwise
+- `lstat' works like `stat'. *Note Symbolic Links::.
+-
+- When the sources are compiled with `_FILE_OFFSET_BITS == 64' this
+- function is in fact `lstat64' since the LFS interface transparently
+- replaces the normal implementation.
+-
+- - Function: int lstat64 (const char *FILENAME, struct stat64 *BUF)
+- This function is similar to `lstat' but it is also able to work on
+- files larger then 2^31 bytes on 32-bit systems. To be able to do
+- this the result is stored in a variable of type `struct stat64' to
+- which BUF must point.
+-
+- When the sources are compiled with `_FILE_OFFSET_BITS == 64' this
+- function is available under the name `lstat' and so transparently
+- replaces the interface for small files on 32-bit machines.

+-
+-Testing the Type of a File
+---------------------------
+-
+- The "file mode", stored in the `st_mode' field of the file
+-attributes, contains two kinds of information: the file type code, and
+-the access permission bits. This section discusses only the type code,
+-which you can use to tell whether the file is a directory, socket,
+-symbolic link, and so on. For details about access permissions see
+-*Note Permission Bits::.
+-
+- There are two ways you can access the file type information in a file
+-mode. Firstly, for each file type there is a "predicate macro" which
+-examines a given file mode and returns whether it is of that type or
+-not. Secondly, you can mask out the rest of the file mode to leave
+-just the file type code, and compare this against constants for each of
+-the supported file types.
+-
+- All of the symbols listed in this section are defined in the header
+-file `sys/stat.h'.
+-
+- The following predicate macros test the type of a file, given the
+-value M which is the `st_mode' field returned by `stat' on that file:
+-
+- - Macro: int S_ISDIR (mode_t M)
+- This macro returns non-zero if the file is a directory.
+-
+- - Macro: int S_ISCHR (mode_t M)
+- This macro returns non-zero if the file is a character special
+- file (a device like a terminal).
+-
+- - Macro: int S_ISBLK (mode_t M)
+- This macro returns non-zero if the file is a block special file (a
+- device like a disk).
+-
+- - Macro: int S_ISREG (mode_t M)
+- This macro returns non-zero if the file is a regular file.
+-
+- - Macro: int S_ISFIFO (mode_t M)
+- This macro returns non-zero if the file is a FIFO special file, or
+- a pipe. *Note Pipes and FIFOs::.
+-
+- - Macro: int S_ISLNK (mode_t M)
+- This macro returns non-zero if the file is a symbolic link. *Note
+- Symbolic Links::.
+-
+- - Macro: int S_ISSOCK (mode_t M)
+- This macro returns non-zero if the file is a socket. *Note
+- Sockets::.
+-
+- An alternate non-POSIX method of testing the file type is supported
+-for compatibility with BSD. The mode can be bitwise AND-ed with
+-`S_IFMT' to extract the file type code, and compared to the appropriate
+-constant. For example,
+-
+- S_ISCHR (MODE)
+-
+-is equivalent to:
+-
+- ((MODE & S_IFMT) == S_IFCHR)
+-
+- - Macro: int S_IFMT
+- This is a bit mask used to extract the file type code from a mode
+- value.
+-
+- These are the symbolic names for the different file type codes:
+-
+-`S_IFDIR'
+- This is the file type constant of a directory file.
+-
+-`S_IFCHR'
+- This is the file type constant of a character-oriented device file.
+-
+-`S_IFBLK'
+- This is the file type constant of a block-oriented device file.
+-
+-`S_IFREG'
+- This is the file type constant of a regular file.
+-
+-`S_IFLNK'
+- This is the file type constant of a symbolic link.
+-
+-`S_IFSOCK'
+- This is the file type constant of a socket.
+-
+-`S_IFIFO'
+- This is the file type constant of a FIFO or pipe.
+-
+- The POSIX.1b standard introduced a few more objects which possibly
+-can be implemented as object in the filesystem. These are message
+-queues, semaphores, and shared memory objects. To allow
+-differentiating these objects from other files the POSIX standard
+-introduces three new test macros. But unlike the other macros it does
+-not take the value of the `st_mode' field as the parameter. Instead
+-they expect a pointer to the whole `struct stat' structure.
+-
+- - Macro: int S_TYPEISMQ (struct stat *S)
+- If the system implement POSIX message queues as distinct objects
+- and the file is a message queue object, this macro returns a
+- non-zero value. In all other cases the result is zero.
+-
+- - Macro: int S_TYPEISSEM (struct stat *S)
+- If the system implement POSIX semaphores as distinct objects and
+- the file is a semaphore object, this macro returns a non-zero
+- value. In all other cases the result is zero.
+-
+- - Macro: int S_TYPEISSHM (struct stat *S)
+- If the system implement POSIX shared memory objects as distinct
+- objects and the file is an shared memory object, this macro
+- returns a non-zero value. In all other cases the result is zero.

+-
+-File Owner
+-----------
+-
+- Every file has an "owner" which is one of the registered user names
+-defined on the system. Each file also has a "group" which is one of
+-the defined groups. The file owner can often be useful for showing you
+-who edited the file (especially when you edit with GNU Emacs), but its
+-main purpose is for access control.
+-
+- The file owner and group play a role in determining access because
+-the file has one set of access permission bits for the owner, another
+-set that applies to users who belong to the file's group, and a third
+-set of bits that applies to everyone else. *Note Access Permission::,
+-for the details of how access is decided based on this data.
+-
+- When a file is created, its owner is set to the effective user ID of
+-the process that creates it (*note Process Persona::). The file's
+-group ID may be set to either the effective group ID of the process, or
+-the group ID of the directory that contains the file, depending on the
+-system where the file is stored. When you access a remote file system,
+-it behaves according to its own rules, not according to the system your
+-program is running on. Thus, your program must be prepared to encounter
+-either kind of behavior no matter what kind of system you run it on.
+-
+- You can change the owner and/or group owner of an existing file using
+-the `chown' function. This is the primitive for the `chown' and
+-`chgrp' shell commands.
+-
+- The prototype for this function is declared in `unistd.h'.
+-
+- - Function: int chown (const char *FILENAME, uid_t OWNER, gid_t GROUP)
+- The `chown' function changes the owner of the file FILENAME to
+- OWNER, and its group owner to GROUP.
+-
+- Changing the owner of the file on certain systems clears the
+- set-user-ID and set-group-ID permission bits. (This is because
+- those bits may not be appropriate for the new owner.) Other file
+- permission bits are not changed.
+-
+- The return value is `0' on success and `-1' on failure. In
+- addition to the usual file name errors (*note File Name Errors::),
+- the following `errno' error conditions are defined for this
+- function:
+-
+- `EPERM'
+- This process lacks permission to make the requested change.
+-
+- Only privileged users or the file's owner can change the
+- file's group. On most file systems, only privileged users
+- can change the file owner; some file systems allow you to
+- change the owner if you are currently the owner. When you
+- access a remote file system, the behavior you encounter is
+- determined by the system that actually holds the file, not by
+- the system your program is running on.
+-
+- *Note Options for Files::, for information about the
+- `_POSIX_CHOWN_RESTRICTED' macro.
+-
+- `EROFS'
+- The file is on a read-only file system.
+-
+- - Function: int fchown (int FILEDES, int OWNER, int GROUP)
+- This is like `chown', except that it changes the owner of the open
+- file with descriptor FILEDES.
+-
+- The return value from `fchown' is `0' on success and `-1' on
+- failure. The following `errno' error codes are defined for this
+- function:
+-
+- `EBADF'
+- The FILEDES argument is not a valid file descriptor.
+-
+- `EINVAL'
+- The FILEDES argument corresponds to a pipe or socket, not an
+- ordinary file.
+-
+- `EPERM'
+- This process lacks permission to make the requested change.
+- For details see `chmod' above.
+-
+- `EROFS'
+- The file resides on a read-only file system.

+-
+-The Mode Bits for Access Permission
+------------------------------------
+-
+- The "file mode", stored in the `st_mode' field of the file
+-attributes, contains two kinds of information: the file type code, and
+-the access permission bits. This section discusses only the access
+-permission bits, which control who can read or write the file. *Note
+-Testing File Type::, for information about the file type code.
+-
+- All of the symbols listed in this section are defined in the header
+-file `sys/stat.h'.
+-
+- These symbolic constants are defined for the file mode bits that
+-control access permission for the file:
+-
+-`S_IRUSR'
+-`S_IREAD'
+- Read permission bit for the owner of the file. On many systems
+- this bit is 0400. `S_IREAD' is an obsolete synonym provided for
+- BSD compatibility.
+-
+-`S_IWUSR'
+-`S_IWRITE'
+- Write permission bit for the owner of the file. Usually 0200.
+- `S_IWRITE' is an obsolete synonym provided for BSD compatibility.
+-
+-`S_IXUSR'
+-`S_IEXEC'
+- Execute (for ordinary files) or search (for directories)
+- permission bit for the owner of the file. Usually 0100.
+- `S_IEXEC' is an obsolete synonym provided for BSD compatibility.
+-
+-`S_IRWXU'
+- This is equivalent to `(S_IRUSR | S_IWUSR | S_IXUSR)'.
+-
+-`S_IRGRP'
+- Read permission bit for the group owner of the file. Usually 040.
+-
+-`S_IWGRP'
+- Write permission bit for the group owner of the file. Usually 020.
+-
+-`S_IXGRP'
+- Execute or search permission bit for the group owner of the file.
+- Usually 010.
+-
+-`S_IRWXG'
+- This is equivalent to `(S_IRGRP | S_IWGRP | S_IXGRP)'.
+-
+-`S_IROTH'
+- Read permission bit for other users. Usually 04.
+-
+-`S_IWOTH'
+- Write permission bit for other users. Usually 02.
+-
+-`S_IXOTH'
+- Execute or search permission bit for other users. Usually 01.
+-
+-`S_IRWXO'
+- This is equivalent to `(S_IROTH | S_IWOTH | S_IXOTH)'.
+-
+-`S_ISUID'
+- This is the set-user-ID on execute bit, usually 04000. *Note How
+- Change Persona::.
+-
+-`S_ISGID'
+- This is the set-group-ID on execute bit, usually 02000. *Note How
+- Change Persona::.
+-
+-`S_ISVTX'
+- This is the "sticky" bit, usually 01000.
+-
+- For a directory it gives permission to delete a file in that
+- directory only if you own that file. Ordinarily, a user can
+- either delete all the files in a directory or cannot delete any of
+- them (based on whether the user has write permission for the
+- directory). The same restriction applies--you must have both
+- write permission for the directory and own the file you want to
+- delete. The one exception is that the owner of the directory can
+- delete any file in the directory, no matter who owns it (provided
+- the owner has given himself write permission for the directory).
+- This is commonly used for the `/tmp' directory, where anyone may
+- create files but not delete files created by other users.
+-
+- Originally the sticky bit on an executable file modified the
+- swapping policies of the system. Normally, when a program
+- terminated, its pages in core were immediately freed and reused.
+- If the sticky bit was set on the executable file, the system kept
+- the pages in core for a while as if the program were still
+- running. This was advantageous for a program likely to be run
+- many times in succession. This usage is obsolete in modern
+- systems. When a program terminates, its pages always remain in
+- core as long as there is no shortage of memory in the system.
+- When the program is next run, its pages will still be in core if
+- no shortage arose since the last run.
+-
+- On some modern systems where the sticky bit has no useful meaning
+- for an executable file, you cannot set the bit at all for a
+- non-directory. If you try, `chmod' fails with `EFTYPE'; *note
+- Setting Permissions::.
+-
+- Some systems (particularly SunOS) have yet another use for the
+- sticky bit. If the sticky bit is set on a file that is _not_
+- executable, it means the opposite: never cache the pages of this
+- file at all. The main use of this is for the files on an NFS
+- server machine which are used as the swap area of diskless client
+- machines. The idea is that the pages of the file will be cached
+- in the client's memory, so it is a waste of the server's memory to
+- cache them a second time. With this usage the sticky bit also
+- implies that the filesystem may fail to record the file's
+- modification time onto disk reliably (the idea being that no-one
+- cares for a swap file).
+-
+- This bit is only available on BSD systems (and those derived from
+- them). Therefore one has to use the `_BSD_SOURCE' feature select
+- macro to get the definition (*note Feature Test Macros::).
+-
+- The actual bit values of the symbols are listed in the table above
+-so you can decode file mode values when debugging your programs. These
+-bit values are correct for most systems, but they are not guaranteed.
+-
+- *Warning:* Writing explicit numbers for file permissions is bad
+-practice. Not only is it not portable, it also requires everyone who
+-reads your program to remember what the bits mean. To make your program
+-clean use the symbolic names.

+-
+-How Your Access to a File is Decided
+-------------------------------------
+-
+- Recall that the operating system normally decides access permission
+-for a file based on the effective user and group IDs of the process and
+-its supplementary group IDs, together with the file's owner, group and
+-permission bits. These concepts are discussed in detail in *Note
+-Process Persona::.
+-
+- If the effective user ID of the process matches the owner user ID of
+-the file, then permissions for read, write, and execute/search are
+-controlled by the corresponding "user" (or "owner") bits. Likewise, if
+-any of the effective group ID or supplementary group IDs of the process
+-matches the group owner ID of the file, then permissions are controlled
+-by the "group" bits. Otherwise, permissions are controlled by the
+-"other" bits.
+-
+- Privileged users, like `root', can access any file regardless of its
+-permission bits. As a special case, for a file to be executable even
+-by a privileged user, at least one of its execute bits must be set.
+-
+-\1f
+-File: libc.info, Node: Setting Permissions, Next: Testing File Access, Prev: Access Permission, Up: File Attributes
+-
+-Assigning File Permissions
+---------------------------
+-
+- The primitive functions for creating files (for example, `open' or
+-`mkdir') take a MODE argument, which specifies the file permissions to
+-give the newly created file. This mode is modified by the process's
+-"file creation mask", or "umask", before it is used.
+-
+- The bits that are set in the file creation mask identify permissions
+-that are always to be disabled for newly created files. For example, if
+-you set all the "other" access bits in the mask, then newly created
+-files are not accessible at all to processes in the "other" category,
+-even if the MODE argument passed to the create function would permit
+-such access. In other words, the file creation mask is the complement
+-of the ordinary access permissions you want to grant.
+-
+- Programs that create files typically specify a MODE argument that
+-includes all the permissions that make sense for the particular file.
+-For an ordinary file, this is typically read and write permission for
+-all classes of users. These permissions are then restricted as
+-specified by the individual user's own file creation mask.
+-
+- To change the permission of an existing file given its name, call
+-`chmod'. This function uses the specified permission bits and ignores
+-the file creation mask.
+-
+- In normal use, the file creation mask is initialized by the user's
+-login shell (using the `umask' shell command), and inherited by all
+-subprocesses. Application programs normally don't need to worry about
+-the file creation mask. It will automatically do what it is supposed to
+-do.
+-
+- When your program needs to create a file and bypass the umask for its
+-access permissions, the easiest way to do this is to use `fchmod' after
+-opening the file, rather than changing the umask. In fact, changing
+-the umask is usually done only by shells. They use the `umask'
+-function.
+-
+- The functions in this section are declared in `sys/stat.h'.
+-
+- - Function: mode_t umask (mode_t MASK)
+- The `umask' function sets the file creation mask of the current
+- process to MASK, and returns the previous value of the file
+- creation mask.
+-
+- Here is an example showing how to read the mask with `umask'
+- without changing it permanently:
+-
+- mode_t
+- read_umask (void)
+- {
+- mode_t mask = umask (0);
+- umask (mask);
+- return mask;
+- }
+-
+- However, it is better to use `getumask' if you just want to read
+- the mask value, because it is reentrant (at least if you use the
+- GNU operating system).
+-
+- - Function: mode_t getumask (void)
+- Return the current value of the file creation mask for the current
+- process. This function is a GNU extension.
+-
+- - Function: int chmod (const char *FILENAME, mode_t MODE)
+- The `chmod' function sets the access permission bits for the file
+- named by FILENAME to MODE.
+-
+- If FILENAME is a symbolic link, `chmod' changes the permissions of
+- the file pointed to by the link, not those of the link itself.
+-
+- This function returns `0' if successful and `-1' if not. In
+- addition to the usual file name errors (*note File Name Errors::),
+- the following `errno' error conditions are defined for this
+- function:
+-
+- `ENOENT'
+- The named file doesn't exist.
+-
+- `EPERM'
+- This process does not have permission to change the access
+- permissions of this file. Only the file's owner (as judged
+- by the effective user ID of the process) or a privileged user
+- can change them.
+-
+- `EROFS'
+- The file resides on a read-only file system.
+-
+- `EFTYPE'
+- MODE has the `S_ISVTX' bit (the "sticky bit") set, and the
+- named file is not a directory. Some systems do not allow
+- setting the sticky bit on non-directory files, and some do
+- (and only some of those assign a useful meaning to the bit
+- for non-directory files).
+-
+- You only get `EFTYPE' on systems where the sticky bit has no
+- useful meaning for non-directory files, so it is always safe
+- to just clear the bit in MODE and call `chmod' again. *Note
+- Permission Bits::, for full details on the sticky bit.
+-
+- - Function: int fchmod (int FILEDES, int MODE)
+- This is like `chmod', except that it changes the permissions of the
+- currently open file given by FILEDES.
+-
+- The return value from `fchmod' is `0' on success and `-1' on
+- failure. The following `errno' error codes are defined for this
+- function:
+-
+- `EBADF'
+- The FILEDES argument is not a valid file descriptor.
+-
+- `EINVAL'
+- The FILEDES argument corresponds to a pipe or socket, or
+- something else that doesn't really have access permissions.
+-
+- `EPERM'
+- This process does not have permission to change the access
+- permissions of this file. Only the file's owner (as judged
+- by the effective user ID of the process) or a privileged user
+- can change them.
+-
+- `EROFS'
+- The file resides on a read-only file system.

+-
+-Testing Permission to Access a File
+------------------------------------
+-
+- In some situations it is desirable to allow programs to access files
+-or devices even if this is not possible with the permissions granted to
+-the user. One possible solution is to set the setuid-bit of the program
+-file. If such a program is started the _effective_ user ID of the
+-process is changed to that of the owner of the program file. So to
+-allow write access to files like `/etc/passwd', which normally can be
+-written only by the super-user, the modifying program will have to be
+-owned by `root' and the setuid-bit must be set.
+-
+- But beside the files the program is intended to change the user
+-should not be allowed to access any file to which s/he would not have
+-access anyway. The program therefore must explicitly check whether _the
+-user_ would have the necessary access to a file, before it reads or
+-writes the file.
+-
+- To do this, use the function `access', which checks for access
+-permission based on the process's _real_ user ID rather than the
+-effective user ID. (The setuid feature does not alter the real user ID,
+-so it reflects the user who actually ran the program.)
+-
+- There is another way you could check this access, which is easy to
+-describe, but very hard to use. This is to examine the file mode bits
+-and mimic the system's own access computation. This method is
+-undesirable because many systems have additional access control
+-features; your program cannot portably mimic them, and you would not
+-want to try to keep track of the diverse features that different systems
+-have. Using `access' is simple and automatically does whatever is
+-appropriate for the system you are using.
+-
+- `access' is _only_ only appropriate to use in setuid programs. A
+-non-setuid program will always use the effective ID rather than the
+-real ID.
+-
+- The symbols in this section are declared in `unistd.h'.
+-
+- - Function: int access (const char *FILENAME, int HOW)
+- The `access' function checks to see whether the file named by
+- FILENAME can be accessed in the way specified by the HOW argument.
+- The HOW argument either can be the bitwise OR of the flags
+- `R_OK', `W_OK', `X_OK', or the existence test `F_OK'.
+-
+- This function uses the _real_ user and group IDs of the calling
+- process, rather than the _effective_ IDs, to check for access
+- permission. As a result, if you use the function from a `setuid'
+- or `setgid' program (*note How Change Persona::), it gives
+- information relative to the user who actually ran the program.
+-
+- The return value is `0' if the access is permitted, and `-1'
+- otherwise. (In other words, treated as a predicate function,
+- `access' returns true if the requested access is _denied_.)
+-
+- In addition to the usual file name errors (*note File Name
+- Errors::), the following `errno' error conditions are defined for
+- this function:
+-
+- `EACCES'
+- The access specified by HOW is denied.
+-
+- `ENOENT'
+- The file doesn't exist.
+-
+- `EROFS'
+- Write permission was requested for a file on a read-only file
+- system.
+-
+- These macros are defined in the header file `unistd.h' for use as
+-the HOW argument to the `access' function. The values are integer
+-constants.
+-
+- - Macro: int R_OK
+- Flag meaning test for read permission.
+-
+- - Macro: int W_OK
+- Flag meaning test for write permission.
+-
+- - Macro: int X_OK
+- Flag meaning test for execute/search permission.
+-
+- - Macro: int F_OK
+- Flag meaning test for existence of the file.

+-
+-File Times
+-----------
+-
+- Each file has three time stamps associated with it: its access time,
+-its modification time, and its attribute modification time. These
+-correspond to the `st_atime', `st_mtime', and `st_ctime' members of the
+-`stat' structure; see *Note File Attributes::.
+-
+- All of these times are represented in calendar time format, as
+-`time_t' objects. This data type is defined in `time.h'. For more
+-information about representation and manipulation of time values, see
+-*Note Calendar Time::.
+-
+- Reading from a file updates its access time attribute, and writing
+-updates its modification time. When a file is created, all three time
+-stamps for that file are set to the current time. In addition, the
+-attribute change time and modification time fields of the directory that
+-contains the new entry are updated.
+-
+- Adding a new name for a file with the `link' function updates the
+-attribute change time field of the file being linked, and both the
+-attribute change time and modification time fields of the directory
+-containing the new name. These same fields are affected if a file name
+-is deleted with `unlink', `remove' or `rmdir'. Renaming a file with
+-`rename' affects only the attribute change time and modification time
+-fields of the two parent directories involved, and not the times for
+-the file being renamed.
+-
+- Changing the attributes of a file (for example, with `chmod')
+-updates its attribute change time field.
+-
+- You can also change some of the time stamps of a file explicitly
+-using the `utime' function--all except the attribute change time. You
+-need to include the header file `utime.h' to use this facility.
+-
+- - Data Type: struct utimbuf
+- The `utimbuf' structure is used with the `utime' function to
+- specify new access and modification times for a file. It contains
+- the following members:
+-
+- `time_t actime'
+- This is the access time for the file.
+-
+- `time_t modtime'
+- This is the modification time for the file.
+-
+- - Function: int utime (const char *FILENAME, const struct utimbuf
+- *TIMES)
+- This function is used to modify the file times associated with the
+- file named FILENAME.
+-
+- If TIMES is a null pointer, then the access and modification times
+- of the file are set to the current time. Otherwise, they are set
+- to the values from the `actime' and `modtime' members
+- (respectively) of the `utimbuf' structure pointed to by TIMES.
+-
+- The attribute modification time for the file is set to the current
+- time in either case (since changing the time stamps is itself a
+- modification of the file attributes).
+-
+- The `utime' function returns `0' if successful and `-1' on
+- failure. In addition to the usual file name errors (*note File
+- Name Errors::), the following `errno' error conditions are defined
+- for this function:
+-
+- `EACCES'
+- There is a permission problem in the case where a null
+- pointer was passed as the TIMES argument. In order to update
+- the time stamp on the file, you must either be the owner of
+- the file, have write permission for the file, or be a
+- privileged user.
+-
+- `ENOENT'
+- The file doesn't exist.
+-
+- `EPERM'
+- If the TIMES argument is not a null pointer, you must either
+- be the owner of the file or be a privileged user.
+-
+- `EROFS'
+- The file lives on a read-only file system.
+-
+- Each of the three time stamps has a corresponding microsecond part,
+-which extends its resolution. These fields are called `st_atime_usec',
+-`st_mtime_usec', and `st_ctime_usec'; each has a value between 0 and
+-999,999, which indicates the time in microseconds. They correspond to
+-the `tv_usec' field of a `timeval' structure; see *Note High-Resolution
+-Calendar::.
+-
+- The `utimes' function is like `utime', but also lets you specify the
+-fractional part of the file times. The prototype for this function is
+-in the header file `sys/time.h'.
+-
+- - Function: int utimes (const char *FILENAME, struct timeval TVP[2])
+- This function sets the file access and modification times of the
+- file FILENAME. The new file access time is specified by `TVP[0]',
+- and the new modification time by `TVP[1]'. Similar to `utime', if
+- TVP is a null pointer then the access and modification times of
+- the file are set to the current time. This function comes from
+- BSD.
+-
+- The return values and error conditions are the same as for the
+- `utime' function.
+-
+- - Function: int lutimes (const char *FILENAME, struct timeval TVP[2])
+- This function is like `utimes', except that it does not follow
+- symbolic links. If FILENAME is the name of a symbolic link,
+- `lutimes' sets the file access and modification times of the
+- symbolic link special file itself (as seen by `lstat'; *note
+- Symbolic Links::) while `utimes' sets the file access and
+- modification times of the file the symbolic link refers to. This
+- function comes from FreeBSD, and is not available on all platforms
+- (if not available, it will fail with `ENOSYS').
+-
+- The return values and error conditions are the same as for the
+- `utime' function.
+-
+- - Function: int futimes (int *FD, struct timeval TVP[2])
+- This function is like `utimes', except that it takes an open file
+- descriptor as an argument instead of a file name. *Note Low-Level
+- I/O::. This function comes from FreeBSD, and is not available on
+- all platforms (if not available, it will fail with `ENOSYS').
+-
+- Like `utimes', `futimes' returns `0' on success and `-1' on
+- failure. The following `errno' error conditions are defined for
+- `futimes':
+-
+- `EACCES'
+- There is a permission problem in the case where a null
+- pointer was passed as the TIMES argument. In order to update
+- the time stamp on the file, you must either be the owner of
+- the file, have write permission for the file, or be a
+- privileged user.
+-
+- `EBADF'
+- The FILEDES argument is not a valid file descriptor.
+-
+- `EPERM'
+- If the TIMES argument is not a null pointer, you must either
+- be the owner of the file or be a privileged user.

+-
+-File Size
+----------
+-
+- Normally file sizes are maintained automatically. A file begins
+-with a size of 0 and is automatically extended when data is written past
+-its end. It is also possible to empty a file completely by an `open'
+-or `fopen' call.
+-
+- However, sometimes it is necessary to _reduce_ the size of a file.
+-This can be done with the `truncate' and `ftruncate' functions. They
+-were introduced in BSD Unix. `ftruncate' was later added to POSIX.1.
+-
+- Some systems allow you to extend a file (creating holes) with these
+-functions. This is useful when using memory-mapped I/O (*note
+-Memory-mapped I/O::), where files are not automatically extended.
+-However, it is not portable but must be implemented if `mmap' allows
+-mapping of files (i.e., `_POSIX_MAPPED_FILES' is defined).
+-
+- Using these functions on anything other than a regular file gives
+-_undefined_ results. On many systems, such a call will appear to
+-succeed, without actually accomplishing anything.
+-
+- - Function: int truncate (const char *FILENAME, off_t LENGTH)
+- The `truncate' function changes the size of FILENAME to LENGTH.
+- If LENGTH is shorter than the previous length, data at the end
+- will be lost. The file must be writable by the user to perform
+- this operation.
+-
+- If LENGTH is longer, holes will be added to the end. However, some
+- systems do not support this feature and will leave the file
+- unchanged.
+-
+- When the source file is compiled with `_FILE_OFFSET_BITS == 64' the
+- `truncate' function is in fact `truncate64' and the type `off_t'
+- has 64 bits which makes it possible to handle files up to 2^63
+- bytes in length.
+-
+- The return value is 0 for success, or -1 for an error. In
+- addition to the usual file name errors, the following errors may
+- occur:
+-
+- `EACCES'
+- The file is a directory or not writable.
+-
+- `EINVAL'
+- LENGTH is negative.
+-
+- `EFBIG'
+- The operation would extend the file beyond the limits of the
+- operating system.
+-
+- `EIO'
+- A hardware I/O error occurred.
+-
+- `EPERM'
+- The file is "append-only" or "immutable".
+-
+- `EINTR'
+- The operation was interrupted by a signal.
+-
+-
+- - Function: int truncate64 (const char *NAME, off64_t LENGTH)
+- This function is similar to the `truncate' function. The
+- difference is that the LENGTH argument is 64 bits wide even on 32
+- bits machines, which allows the handling of files with sizes up to
+- 2^63 bytes.
+-
+- When the source file is compiled with `_FILE_OFFSET_BITS == 64' on
+- a 32 bits machine this function is actually available under the
+- name `truncate' and so transparently replaces the 32 bits
+- interface.
+-
+- - Function: int ftruncate (int FD, off_t LENGTH)
+- This is like `truncate', but it works on a file descriptor FD for
+- an opened file instead of a file name to identify the object. The
+- file must be opened for writing to successfully carry out the
+- operation.
+-
+- The POSIX standard leaves it implementation defined what happens
+- if the specified new LENGTH of the file is bigger than the
+- original size. The `ftruncate' function might simply leave the
+- file alone and do nothing or it can increase the size to the
+- desired size. In this later case the extended area should be
+- zero-filled. So using `ftruncate' is no reliable way to increase
+- the file size but if it is possible it is probably the fastest
+- way. The function also operates on POSIX shared memory segments
+- if these are implemented by the system.
+-
+- `ftruncate' is especially useful in combination with `mmap'.
+- Since the mapped region must have a fixed size one cannot enlarge
+- the file by writing something beyond the last mapped page.
+- Instead one has to enlarge the file itself and then remap the file
+- with the new size. The example below shows how this works.
+-
+- When the source file is compiled with `_FILE_OFFSET_BITS == 64' the
+- `ftruncate' function is in fact `ftruncate64' and the type `off_t'
+- has 64 bits which makes it possible to handle files up to 2^63
+- bytes in length.
+-
+- The return value is 0 for success, or -1 for an error. The
+- following errors may occur:
+-
+- `EBADF'
+- FD does not correspond to an open file.
+-
+- `EACCES'
+- FD is a directory or not open for writing.
+-
+- `EINVAL'
+- LENGTH is negative.
+-
+- `EFBIG'
+- The operation would extend the file beyond the limits of the
+- operating system.
+-
+- `EIO'
+- A hardware I/O error occurred.
+-
+- `EPERM'
+- The file is "append-only" or "immutable".
+-
+- `EINTR'
+- The operation was interrupted by a signal.
+-
+-
+- - Function: int ftruncate64 (int ID, off64_t LENGTH)
+- This function is similar to the `ftruncate' function. The
+- difference is that the LENGTH argument is 64 bits wide even on 32
+- bits machines which allows the handling of files with sizes up to
+- 2^63 bytes.
+-
+- When the source file is compiled with `_FILE_OFFSET_BITS == 64' on
+- a 32 bits machine this function is actually available under the
+- name `ftruncate' and so transparently replaces the 32 bits
+- interface.
+-
+- As announced here is a little example of how to use `ftruncate' in
+-combination with `mmap':
+-
+- int fd;
+- void *start;
+- size_t len;
+-
+- int
+- add (off_t at, void *block, size_t size)
+- {
+- if (at + size > len)
+- {
+- /* Resize the file and remap. */
+- size_t ps = sysconf (_SC_PAGESIZE);
+- size_t ns = (at + size + ps - 1) & ~(ps - 1);
+- void *np;
+- if (ftruncate (fd, ns) < 0)
+- return -1;
+- np = mmap (NULL, ns, PROT_READ|PROT_WRITE, MAP_SHARED, fd, 0);
+- if (np == MAP_FAILED)
+- return -1;
+- start = np;
+- len = ns;
+- }
+- memcpy ((char *) start + at, block, size);
+- return 0;
+- }
+-
+- The function `add' writes a block of memory at an arbitrary position
+-in the file. If the current size of the file is too small it is
+-extended. Note the it is extended by a round number of pages. This is
+-a requirement of `mmap'. The program has to keep track of the real
+-size, and when it has finished a final `ftruncate' call should set the
+-real size of the file.

+-Making Special Files
+-====================
+-
+- The `mknod' function is the primitive for making special files, such
+-as files that correspond to devices. The GNU library includes this
+-function for compatibility with BSD.
+-
+- The prototype for `mknod' is declared in `sys/stat.h'.
+-
+- - Function: int mknod (const char *FILENAME, int MODE, int DEV)
+- The `mknod' function makes a special file with name FILENAME. The
+- MODE specifies the mode of the file, and may include the various
+- special file bits, such as `S_IFCHR' (for a character special file)
+- or `S_IFBLK' (for a block special file). *Note Testing File
+- Type::.
+-
+- The DEV argument specifies which device the special file refers to.
+- Its exact interpretation depends on the kind of special file being
+- created.
+-
+- The return value is `0' on success and `-1' on error. In addition
+- to the usual file name errors (*note File Name Errors::), the
+- following `errno' error conditions are defined for this function:
+-
+- `EPERM'
+- The calling process is not privileged. Only the superuser
+- can create special files.
+-
+- `ENOSPC'
+- The directory or file system that would contain the new file
+- is full and cannot be extended.
+-
+- `EROFS'
+- The directory containing the new file can't be modified
+- because it's on a read-only file system.
+-
+- `EEXIST'
+- There is already a file named FILENAME. If you want to
+- replace this file, you must remove the old file explicitly
+- first.

+-File: libc.info, Node: Temporary Files, Prev: Making Special Files, Up: File System Interface
+-
+-Temporary Files
+-===============
+-
+- If you need to use a temporary file in your program, you can use the
+-`tmpfile' function to open it. Or you can use the `tmpnam' (better:
+-`tmpnam_r') function to provide a name for a temporary file and then
+-you can open it in the usual way with `fopen'.
+-
+- The `tempnam' function is like `tmpnam' but lets you choose what
+-directory temporary files will go in, and something about what their
+-file names will look like. Important for multi-threaded programs is
+-that `tempnam' is reentrant, while `tmpnam' is not since it returns a
+-pointer to a static buffer.
+-
+- These facilities are declared in the header file `stdio.h'.
+-
+- - Function: FILE * tmpfile (void)
+- This function creates a temporary binary file for update mode, as
+- if by calling `fopen' with mode `"wb+"'. The file is deleted
+- automatically when it is closed or when the program terminates.
+- (On some other ISO C systems the file may fail to be deleted if
+- the program terminates abnormally).
+-
+- This function is reentrant.
+-
+- When the sources are compiled with `_FILE_OFFSET_BITS == 64' on a
+- 32-bit system this function is in fact `tmpfile64', i.e. the LFS
+- interface transparently replaces the old interface.
+-
+- - Function: FILE * tmpfile64 (void)
+- This function is similar to `tmpfile', but the stream it returns a
+- pointer to was opened using `tmpfile64'. Therefore this stream can
+- be used for files larger then 2^31 bytes on 32-bit machines.
+-
+- Please note that the return type is still `FILE *'. There is no
+- special `FILE' type for the LFS interface.
+-
+- If the sources are compiled with `_FILE_OFFSET_BITS == 64' on a 32
+- bits machine this function is available under the name `tmpfile'
+- and so transparently replaces the old interface.
+-
+- - Function: char * tmpnam (char *RESULT)
+- This function constructs and returns a valid file name that does
+- not refer to any existing file. If the RESULT argument is a null
+- pointer, the return value is a pointer to an internal static
+- string, which might be modified by subsequent calls and therefore
+- makes this function non-reentrant. Otherwise, the RESULT argument
+- should be a pointer to an array of at least `L_tmpnam' characters,
+- and the result is written into that array.
+-
+- It is possible for `tmpnam' to fail if you call it too many times
+- without removing previously-created files. This is because the
+- limited length of the temporary file names gives room for only a
+- finite number of different names. If `tmpnam' fails it returns a
+- null pointer.
+-
+- *Warning:* Between the time the pathname is constructed and the
+- file is created another process might have created a file with the
+- same name using `tmpnam', leading to a possible security hole. The
+- implementation generates names which can hardly be predicted, but
+- when opening the file you should use the `O_EXCL' flag. Using
+- `tmpfile' or `mkstemp' is a safe way to avoid this problem.
+-
+- - Function: char * tmpnam_r (char *RESULT)
+- This function is nearly identical to the `tmpnam' function, except
+- that if RESULT is a null pointer it returns a null pointer.
+-
+- This guarantees reentrancy because the non-reentrant situation of
+- `tmpnam' cannot happen here.
+-
+- *Warning*: This function has the same security problems as
+- `tmpnam'.
+-
+- - Macro: int L_tmpnam
+- The value of this macro is an integer constant expression that
+- represents the minimum size of a string large enough to hold a
+- file name generated by the `tmpnam' function.
+-
+- - Macro: int TMP_MAX
+- The macro `TMP_MAX' is a lower bound for how many temporary names
+- you can create with `tmpnam'. You can rely on being able to call
+- `tmpnam' at least this many times before it might fail saying you
+- have made too many temporary file names.
+-
+- With the GNU library, you can create a very large number of
+- temporary file names. If you actually created the files, you
+- would probably run out of disk space before you ran out of names.
+- Some other systems have a fixed, small limit on the number of
+- temporary files. The limit is never less than `25'.
+-
+- - Function: char * tempnam (const char *DIR, const char *PREFIX)
+- This function generates a unique temporary file name. If PREFIX
+- is not a null pointer, up to five characters of this string are
+- used as a prefix for the file name. The return value is a string
+- newly allocated with `malloc', so you should release its storage
+- with `free' when it is no longer needed.
+-
+- Because the string is dynamically allocated this function is
+- reentrant.
+-
+- The directory prefix for the temporary file name is determined by
+- testing each of the following in sequence. The directory must
+- exist and be writable.
+-
+- * The environment variable `TMPDIR', if it is defined. For
+- security reasons this only happens if the program is not SUID
+- or SGID enabled.
+-
+- * The DIR argument, if it is not a null pointer.
+-
+- * The value of the `P_tmpdir' macro.
+-
+- * The directory `/tmp'.
+-
+- This function is defined for SVID compatibility.
+-
+- *Warning:* Between the time the pathname is constructed and the
+- file is created another process might have created a file with the
+- same name using `tempnam', leading to a possible security hole.
+- The implementation generates names which can hardly be predicted,
+- but when opening the file you should use the `O_EXCL' flag. Using
+- `tmpfile' or `mkstemp' is a safe way to avoid this problem.
+-
+- - SVID Macro: char * P_tmpdir
+- This macro is the name of the default directory for temporary
+- files.
+-
+- Older Unix systems did not have the functions just described.
+-Instead they used `mktemp' and `mkstemp'. Both of these functions work
+-by modifying a file name template string you pass. The last six
+-characters of this string must be `XXXXXX'. These six `X's are
+-replaced with six characters which make the whole string a unique file
+-name. Usually the template string is something like
+-`/tmp/PREFIXXXXXXX', and each program uses a unique PREFIX.
+-
+- *Note:* Because `mktemp' and `mkstemp' modify the template string,
+-you _must not_ pass string constants to them. String constants are
+-normally in read-only storage, so your program would crash when
+-`mktemp' or `mkstemp' tried to modify the string.
+-
+- - Function: char * mktemp (char *TEMPLATE)
+- The `mktemp' function generates a unique file name by modifying
+- TEMPLATE as described above. If successful, it returns TEMPLATE
+- as modified. If `mktemp' cannot find a unique file name, it makes
+- TEMPLATE an empty string and returns that. If TEMPLATE does not
+- end with `XXXXXX', `mktemp' returns a null pointer.
+-
+- *Warning:* Between the time the pathname is constructed and the
+- file is created another process might have created a file with the
+- same name using `mktemp', leading to a possible security hole. The
+- implementation generates names which can hardly be predicted, but
+- when opening the file you should use the `O_EXCL' flag. Using
+- `mkstemp' is a safe way to avoid this problem.
+-
+- - Function: int mkstemp (char *TEMPLATE)
+- The `mkstemp' function generates a unique file name just as
+- `mktemp' does, but it also opens the file for you with `open'
+- (*note Opening and Closing Files::). If successful, it modifies
+- TEMPLATE in place and returns a file descriptor for that file open
+- for reading and writing. If `mkstemp' cannot create a
+- uniquely-named file, it returns `-1'. If TEMPLATE does not end
+- with `XXXXXX', `mkstemp' returns `-1' and does not modify TEMPLATE.
+-
+- The file is opened using mode `0600'. If the file is meant to be
+- used by other users this mode must be changed explicitly.
+-
+- Unlike `mktemp', `mkstemp' is actually guaranteed to create a unique
+-file that cannot possibly clash with any other program trying to create
+-a temporary file. This is because it works by calling `open' with the
+-`O_EXCL' flag, which says you want to create a new file and get an
+-error if the file already exists.
+-
+- - Function: char * mkdtemp (char *TEMPLATE)
+- The `mkdtemp' function creates a directory with a unique name. If
+- it succeeds, it overwrites TEMPLATE with the name of the
+- directory, and returns TEMPLATE. As with `mktemp' and `mkstemp',
+- TEMPLATE should be a string ending with `XXXXXX'.
+-
+- If `mkdtemp' cannot create an uniquely named directory, it returns
+- `NULL' and sets ERRNO appropriately. If TEMPLATE does not end
+- with `XXXXXX', `mkdtemp' returns `NULL' and does not modify
+- TEMPLATE. ERRNO will be set to `EINVAL' in this case.
+-
+- The directory is created using mode `0700'.
+-
+- The directory created by `mkdtemp' cannot clash with temporary files
+-or directories created by other users. This is because directory
+-creation always works like `open' with `O_EXCL'. *Note Creating
+-Directories::.
+-
+- The `mkdtemp' function comes from OpenBSD.

+-Pipes and FIFOs
+-***************
+-
+- A "pipe" is a mechanism for interprocess communication; data written
+-to the pipe by one process can be read by another process. The data is
+-handled in a first-in, first-out (FIFO) order. The pipe has no name; it
+-is created for one use and both ends must be inherited from the single
+-process which created the pipe.
+-
+- A "FIFO special file" is similar to a pipe, but instead of being an
+-anonymous, temporary connection, a FIFO has a name or names like any
+-other file. Processes open the FIFO by name in order to communicate
+-through it.
+-
+- A pipe or FIFO has to be open at both ends simultaneously. If you
+-read from a pipe or FIFO file that doesn't have any processes writing
+-to it (perhaps because they have all closed the file, or exited), the
+-read returns end-of-file. Writing to a pipe or FIFO that doesn't have a
+-reading process is treated as an error condition; it generates a
+-`SIGPIPE' signal, and fails with error code `EPIPE' if the signal is
+-handled or blocked.
+-
+- Neither pipes nor FIFO special files allow file positioning. Both
+-reading and writing operations happen sequentially; reading from the
+-beginning of the file and writing at the end.

+-Creating a Pipe
+-===============
+-
+- The primitive for creating a pipe is the `pipe' function. This
+-creates both the reading and writing ends of the pipe. It is not very
+-useful for a single process to use a pipe to talk to itself. In typical
+-use, a process creates a pipe just before it forks one or more child
+-processes (*note Creating a Process::). The pipe is then used for
+-communication either between the parent or child processes, or between
+-two sibling processes.
+-
+- The `pipe' function is declared in the header file `unistd.h'.
+-
+- - Function: int pipe (int FILEDES[2])
+- The `pipe' function creates a pipe and puts the file descriptors
+- for the reading and writing ends of the pipe (respectively) into
+- `FILEDES[0]' and `FILEDES[1]'.
+-
+- An easy way to remember that the input end comes first is that file
+- descriptor `0' is standard input, and file descriptor `1' is
+- standard output.
+-
+- If successful, `pipe' returns a value of `0'. On failure, `-1' is
+- returned. The following `errno' error conditions are defined for
+- this function:
+-
+- `EMFILE'
+- The process has too many files open.
+-
+- `ENFILE'
+- There are too many open files in the entire system. *Note
+- Error Codes::, for more information about `ENFILE'. This
+- error never occurs in the GNU system.
+-
+- Here is an example of a simple program that creates a pipe. This
+-program uses the `fork' function (*note Creating a Process::) to create
+-a child process. The parent process writes data to the pipe, which is
+-read by the child process.

+-
+-Pipe to a Subprocess
+-====================
+-
+- A common use of pipes is to send data to or receive data from a
+-program being run as a subprocess. One way of doing this is by using a
+-combination of `pipe' (to create the pipe), `fork' (to create the
+-subprocess), `dup2' (to force the subprocess to use the pipe as its
+-standard input or output channel), and `exec' (to execute the new
+-program). Or, you can use `popen' and `pclose'.
+-
+- The advantage of using `popen' and `pclose' is that the interface is
+-much simpler and easier to use. But it doesn't offer as much
+-flexibility as using the low-level functions directly.
+-
+- - Function: FILE * popen (const char *COMMAND, const char *MODE)
+- The `popen' function is closely related to the `system' function;
+- see *Note Running a Command::. It executes the shell command
+- COMMAND as a subprocess. However, instead of waiting for the
+- command to complete, it creates a pipe to the subprocess and
+- returns a stream that corresponds to that pipe.
+-
+- If you specify a MODE argument of `"r"', you can read from the
+- stream to retrieve data from the standard output channel of the
+- subprocess. The subprocess inherits its standard input channel
+- from the parent process.
+-
+- Similarly, if you specify a MODE argument of `"w"', you can write
+- to the stream to send data to the standard input channel of the
+- subprocess. The subprocess inherits its standard output channel
+- from the parent process.
+-
+- In the event of an error `popen' returns a null pointer. This
+- might happen if the pipe or stream cannot be created, if the
+- subprocess cannot be forked, or if the program cannot be executed.
+-
+- - Function: int pclose (FILE *STREAM)
+- The `pclose' function is used to close a stream created by `popen'.
+- It waits for the child process to terminate and returns its status
+- value, as for the `system' function.
+-
+- Here is an example showing how to use `popen' and `pclose' to filter
+-output through another program, in this case the paging program `more'.
+-
+- #include <stdio.h>
+- #include <stdlib.h>
+-
+- void
+- write_data (FILE * stream)
+- {
+- int i;
+- for (i = 0; i < 100; i++)
+- fprintf (stream, "%d\n", i);
+- if (ferror (stream))
+- {
+- fprintf (stderr, "Output to stream failed.\n");
+- exit (EXIT_FAILURE);
+- }
+- }
+-
+- int
+- main (void)
+- {
+- FILE *output;
+-
+- output = popen ("more", "w");
+- if (!output)
+- {
+- fprintf (stderr,
+- "incorrect parameters or too many files.\n");
+- return EXIT_FAILURE;
+- }
+- write_data (output);
+- if (pclose (output) != 0)
+- {
+- fprintf (stderr,
+- "Could not run more or other error.\n");

+-FIFO Special Files
+-==================
+-
+- A FIFO special file is similar to a pipe, except that it is created
+-in a different way. Instead of being an anonymous communications
+-channel, a FIFO special file is entered into the file system by calling
+-`mkfifo'.
+-
+- Once you have created a FIFO special file in this way, any process
+-can open it for reading or writing, in the same way as an ordinary file.
+-However, it has to be open at both ends simultaneously before you can
+-proceed to do any input or output operations on it. Opening a FIFO for
+-reading normally blocks until some other process opens the same FIFO for
+-writing, and vice versa.
+-
+- The `mkfifo' function is declared in the header file `sys/stat.h'.
+-
+- - Function: int mkfifo (const char *FILENAME, mode_t MODE)
+- The `mkfifo' function makes a FIFO special file with name
+- FILENAME. The MODE argument is used to set the file's
+- permissions; see *Note Setting Permissions::.
+-
+- The normal, successful return value from `mkfifo' is `0'. In the
+- case of an error, `-1' is returned. In addition to the usual file
+- name errors (*note File Name Errors::), the following `errno'
+- error conditions are defined for this function:
+-
+- `EEXIST'
+- The named file already exists.
+-
+- `ENOSPC'
+- The directory or file system cannot be extended.
+-
+- `EROFS'
+- The directory that would contain the file resides on a
+- read-only file system.

+-
+-Atomicity of Pipe I/O
+-=====================
+-
+- Reading or writing pipe data is "atomic" if the size of data written
+-is not greater than `PIPE_BUF'. This means that the data transfer
+-seems to be an instantaneous unit, in that nothing else in the system
+-can observe a state in which it is partially complete. Atomic I/O may
+-not begin right away (it may need to wait for buffer space or for data),
+-but once it does begin it finishes immediately.
+-
+- Reading or writing a larger amount of data may not be atomic; for
+-example, output data from other processes sharing the descriptor may be
+-interspersed. Also, once `PIPE_BUF' characters have been written,
+-further writes will block until some characters are read.
+-
+- *Note Limits for Files::, for information about the `PIPE_BUF'
+-parameter.

+-Sockets
+-*******
+-
+- This chapter describes the GNU facilities for interprocess
+-communication using sockets.
+-
+- A "socket" is a generalized interprocess communication channel.
+-Like a pipe, a socket is represented as a file descriptor. Unlike pipes
+-sockets support communication between unrelated processes, and even
+-between processes running on different machines that communicate over a
+-network. Sockets are the primary means of communicating with other
+-machines; `telnet', `rlogin', `ftp', `talk' and the other familiar
+-network programs use sockets.
+-
+- Not all operating systems support sockets. In the GNU library, the
+-header file `sys/socket.h' exists regardless of the operating system,
+-and the socket functions always exist, but if the system does not
+-really support sockets these functions always fail.
+-
+- *Incomplete:* We do not currently document the facilities for
+-broadcast messages or for configuring Internet interfaces. The
+-reentrant functions and some newer functions that are related to IPv6
+-aren't documented either so far.

+-Socket Concepts
+-===============
+-
+- When you create a socket, you must specify the style of communication
+-you want to use and the type of protocol that should implement it. The
+-"communication style" of a socket defines the user-level semantics of
+-sending and receiving data on the socket. Choosing a communication
+-style specifies the answers to questions such as these:
+-
+- * *What are the units of data transmission?* Some communication
+- styles regard the data as a sequence of bytes with no larger
+- structure; others group the bytes into records (which are known in
+- this context as "packets").
+-
+- * *Can data be lost during normal operation?* Some communication
+- styles guarantee that all the data sent arrives in the order it was
+- sent (barring system or network crashes); other styles occasionally
+- lose data as a normal part of operation, and may sometimes deliver
+- packets more than once or in the wrong order.
+-
+- Designing a program to use unreliable communication styles usually
+- involves taking precautions to detect lost or misordered packets
+- and to retransmit data as needed.
+-
+- * *Is communication entirely with one partner?* Some communication
+- styles are like a telephone call--you make a "connection" with one
+- remote socket and then exchange data freely. Other styles are
+- like mailing letters--you specify a destination address for each
+- message you send.
+-
+- You must also choose a "namespace" for naming the socket. A socket
+-name ("address") is meaningful only in the context of a particular
+-namespace. In fact, even the data type to use for a socket name may
+-depend on the namespace. Namespaces are also called "domains", but we
+-avoid that word as it can be confused with other usage of the same
+-term. Each namespace has a symbolic name that starts with `PF_'. A
+-corresponding symbolic name starting with `AF_' designates the address
+-format for that namespace.
+-
+- Finally you must choose the "protocol" to carry out the
+-communication. The protocol determines what low-level mechanism is used
+-to transmit and receive data. Each protocol is valid for a particular
+-namespace and communication style; a namespace is sometimes called a
+-"protocol family" because of this, which is why the namespace names
+-start with `PF_'.
+-
+- The rules of a protocol apply to the data passing between two
+-programs, perhaps on different computers; most of these rules are
+-handled by the operating system and you need not know about them. What
+-you do need to know about protocols is this:
+-
+- * In order to have communication between two sockets, they must
+- specify the _same_ protocol.
+-
+- * Each protocol is meaningful with particular style/namespace
+- combinations and cannot be used with inappropriate combinations.
+- For example, the TCP protocol fits only the byte stream style of
+- communication and the Internet namespace.
+-
+- * For each combination of style and namespace there is a "default
+- protocol", which you can request by specifying 0 as the protocol
+- number. And that's what you should normally do--use the default.
+-
+- Throughout the following description at various places
+-variables/parameters to denote sizes are required. And here the trouble
+-starts. In the first implementations the type of these variables was
+-simply `int'. On most machines at that time an `int' was 32 bits wide,
+-which created a _de facto_ standard requiring 32-bit variables. This
+-is important since references to variables of this type are passed to
+-the kernel.
+-
+- Then the POSIX people came and unified the interface with the words
+-"all size values are of type `size_t'". On 64-bit machines `size_t' is
+-64 bits wide, so pointers to variables were no longer possible.
+-
+- The Unix98 specification provides a solution by introducing a type
+-`socklen_t'. This type is used in all of the cases that POSIX changed
+-to use `size_t'. The only requirement of this type is that it be an
+-unsigned type of at least 32 bits. Therefore, implementations which
+-require that references to 32-bit variables be passed can be as happy
+-as implementations which use 64-bit values.

+-Communication Styles
+-====================
+-
+- The GNU library includes support for several different kinds of
+-sockets, each with different characteristics. This section describes
+-the supported socket types. The symbolic constants listed here are
+-defined in `sys/socket.h'.
+-
+- - Macro: int SOCK_STREAM
+- The `SOCK_STREAM' style is like a pipe (*note Pipes and FIFOs::).
+- It operates over a connection with a particular remote socket and
+- transmits data reliably as a stream of bytes.
+-
+- Use of this style is covered in detail in *Note Connections::.
+-
+- - Macro: int SOCK_DGRAM
+- The `SOCK_DGRAM' style is used for sending individually-addressed
+- packets unreliably. It is the diametrical opposite of
+- `SOCK_STREAM'.
+-
+- Each time you write data to a socket of this kind, that data
+- becomes one packet. Since `SOCK_DGRAM' sockets do not have
+- connections, you must specify the recipient address with each
+- packet.
+-
+- The only guarantee that the system makes about your requests to
+- transmit data is that it will try its best to deliver each packet
+- you send. It may succeed with the sixth packet after failing with
+- the fourth and fifth packets; the seventh packet may arrive before
+- the sixth, and may arrive a second time after the sixth.
+-
+- The typical use for `SOCK_DGRAM' is in situations where it is
+- acceptable to simply re-send a packet if no response is seen in a
+- reasonable amount of time.
+-
+- *Note Datagrams::, for detailed information about how to use
+- datagram sockets.
+-
+- - Macro: int SOCK_RAW
+- This style provides access to low-level network protocols and
+- interfaces. Ordinary user programs usually have no need to use
+- this style.

+-
+-Socket Addresses
+-================
+-
+- The name of a socket is normally called an "address". The functions
+-and symbols for dealing with socket addresses were named
+-inconsistently, sometimes using the term "name" and sometimes using
+-"address". You can regard these terms as synonymous where sockets are
+-concerned.
+-
+- A socket newly created with the `socket' function has no address.
+-Other processes can find it for communication only if you give it an
+-address. We call this "binding" the address to the socket, and the way
+-to do it is with the `bind' function.
+-
+- You need be concerned with the address of a socket if other processes
+-are to find it and start communicating with it. You can specify an
+-address for other sockets, but this is usually pointless; the first time
+-you send data from a socket, or use it to initiate a connection, the
+-system assigns an address automatically if you have not specified one.
+-
+- Occasionally a client needs to specify an address because the server
+-discriminates based on address; for example, the rsh and rlogin
+-protocols look at the client's socket address and only bypass password
+-checking if it is less than `IPPORT_RESERVED' (*note Ports::).
+-
+- The details of socket addresses vary depending on what namespace you
+-are using. *Note Local Namespace::, or *Note Internet Namespace::, for
+-specific information.
+-
+- Regardless of the namespace, you use the same functions `bind' and
+-`getsockname' to set and examine a socket's address. These functions
+-use a phony data type, `struct sockaddr *', to accept the address. In
+-practice, the address lives in a structure of some other data type
+-appropriate to the address format you are using, but you cast its
+-address to `struct sockaddr *' when you pass it to `bind'.

+-

+-
+-Address Formats
+----------------
+-
+- The functions `bind' and `getsockname' use the generic data type
+-`struct sockaddr *' to represent a pointer to a socket address. You
+-can't use this data type effectively to interpret an address or
+-construct one; for that, you must use the proper data type for the
+-socket's namespace.
+-
+- Thus, the usual practice is to construct an address of the proper
+-namespace-specific type, then cast a pointer to `struct sockaddr *'
+-when you call `bind' or `getsockname'.
+-
+- The one piece of information that you can get from the `struct
+-sockaddr' data type is the "address format designator". This tells you
+-which data type to use to understand the address fully.
+-
+- The symbols in this section are defined in the header file
+-`sys/socket.h'.
+-
+- - Data Type: struct sockaddr
+- The `struct sockaddr' type itself has the following members:
+-
+- `short int sa_family'
+- This is the code for the address format of this address. It
+- identifies the format of the data which follows.
+-
+- `char sa_data[14]'
+- This is the actual socket address data, which is
+- format-dependent. Its length also depends on the format, and
+- may well be more than 14. The length 14 of `sa_data' is
+- essentially arbitrary.
+-
+- Each address format has a symbolic name which starts with `AF_'.
+-Each of them corresponds to a `PF_' symbol which designates the
+-corresponding namespace. Here is a list of address format names:
+-
+-`AF_LOCAL'
+- This designates the address format that goes with the local
+- namespace. (`PF_LOCAL' is the name of that namespace.) *Note
+- Local Namespace Details::, for information about this address
+- format.
+-
+-`AF_UNIX'
+- This is a synonym for `AF_LOCAL'. Although `AF_LOCAL' is mandated
+- by POSIX.1g, `AF_UNIX' is portable to more systems. `AF_UNIX' was
+- the traditional name stemming from BSD, so even most POSIX systems
+- support it. It is also the name of choice in the Unix98
+- specification. (The same is true for `PF_UNIX' vs. `PF_LOCAL').
+-
+-`AF_FILE'
+- This is another synonym for `AF_LOCAL', for compatibility.
+- (`PF_FILE' is likewise a synonym for `PF_LOCAL'.)
+-
+-`AF_INET'
+- This designates the address format that goes with the Internet
+- namespace. (`PF_INET' is the name of that namespace.) *Note
+- Internet Address Formats::.
+-
+-`AF_INET6'
+- This is similar to `AF_INET', but refers to the IPv6 protocol.
+- (`PF_INET6' is the name of the corresponding namespace.)
+-
+-`AF_UNSPEC'
+- This designates no particular address format. It is used only in
+- rare cases, such as to clear out the default destination address
+- of a "connected" datagram socket. *Note Sending Datagrams::.
+-
+- The corresponding namespace designator symbol `PF_UNSPEC' exists
+- for completeness, but there is no reason to use it in a program.
+-
+- `sys/socket.h' defines symbols starting with `AF_' for many
+-different kinds of networks, most or all of which are not actually
+-implemented. We will document those that really work as we receive
+-information about how to use them.

+-Setting the Address of a Socket
+--------------------------------
+-
+- Use the `bind' function to assign an address to a socket. The
+-prototype for `bind' is in the header file `sys/socket.h'. For
+-examples of use, see *Note Local Socket Example::, or see *Note Inet
+-Example::.
+-
+- - Function: int bind (int SOCKET, struct sockaddr *ADDR, socklen_t
+- LENGTH)
+- The `bind' function assigns an address to the socket SOCKET. The
+- ADDR and LENGTH arguments specify the address; the detailed format
+- of the address depends on the namespace. The first part of the
+- address is always the format designator, which specifies a
+- namespace, and says that the address is in the format of that
+- namespace.
+-
+- The return value is `0' on success and `-1' on failure. The
+- following `errno' error conditions are defined for this function:
+-
+- `EBADF'
+- The SOCKET argument is not a valid file descriptor.
+-
+- `ENOTSOCK'
+- The descriptor SOCKET is not a socket.
+-
+- `EADDRNOTAVAIL'
+- The specified address is not available on this machine.
+-
+- `EADDRINUSE'
+- Some other socket is already using the specified address.
+-
+- `EINVAL'
+- The socket SOCKET already has an address.
+-
+- `EACCES'
+- You do not have permission to access the requested address.
+- (In the Internet domain, only the super-user is allowed to
+- specify a port number in the range 0 through
+- `IPPORT_RESERVED' minus one; see *Note Ports::.)
+-
+- Additional conditions may be possible depending on the particular
+- namespace of the socket.

+-Reading the Address of a Socket
+--------------------------------
+-
+- Use the function `getsockname' to examine the address of an Internet
+-socket. The prototype for this function is in the header file
+-`sys/socket.h'.
+-
+- - Function: int getsockname (int SOCKET, struct sockaddr *ADDR,
+- socklen_t *LENGTH-PTR)
+- The `getsockname' function returns information about the address
+- of the socket SOCKET in the locations specified by the ADDR and
+- LENGTH-PTR arguments. Note that the LENGTH-PTR is a pointer; you
+- should initialize it to be the allocation size of ADDR, and on
+- return it contains the actual size of the address data.
+-
+- The format of the address data depends on the socket namespace.
+- The length of the information is usually fixed for a given
+- namespace, so normally you can know exactly how much space is
+- needed and can provide that much. The usual practice is to
+- allocate a place for the value using the proper data type for the
+- socket's namespace, then cast its address to `struct sockaddr *'
+- to pass it to `getsockname'.
+-
+- The return value is `0' on success and `-1' on error. The
+- following `errno' error conditions are defined for this function:
+-
+- `EBADF'
+- The SOCKET argument is not a valid file descriptor.
+-
+- `ENOTSOCK'
+- The descriptor SOCKET is not a socket.
+-
+- `ENOBUFS'
+- There are not enough internal buffers available for the
+- operation.
+-
+- You can't read the address of a socket in the file namespace. This
+-is consistent with the rest of the system; in general, there's no way to
+-find a file's name from a descriptor for that file.

+-
+-Interface Naming
+-================
+-
+- Each network interface has a name. This usually consists of a few
+-letters that relate to the type of interface, which may be followed by a
+-number if there is more than one interface of that type. Examples
+-might be `lo' (the loopback interface) and `eth0' (the first Ethernet
+-interface).
+-
+- Although such names are convenient for humans, it would be clumsy to
+-have to use them whenever a program needs to refer to an interface. In
+-such situations an interface is referred to by its "index", which is an
+-arbitrarily-assigned small positive integer.
+-
+- The following functions, constants and data types are declared in the
+-header file `net/if.h'.
+-
+- - Constant: size_t IFNAMSIZ
+- This constant defines the maximum buffer size needed to hold an
+- interface name, including its terminating zero byte.
+-
+- - Function: unsigned int if_nametoindex (const char *ifname)
+- This function yields the interface index corresponding to a
+- particular name. If no interface exists with the name given, it
+- returns 0.
+-
+- - Function: char * if_indextoname (unsigned int ifindex, char *ifname)
+- This function maps an interface index to its corresponding name.
+- The returned name is placed in the buffer pointed to by `ifname',
+- which must be at least `IFNAMSIZ' bytes in length. If the index
+- was invalid, the function's return value is a null pointer,
+- otherwise it is `ifname'.
+-
+- - Data Type: struct if_nameindex
+- This data type is used to hold the information about a single
+- interface. It has the following members:
+-
+- `unsigned int if_index;'
+- This is the interface index.
+-
+- `char *if_name'
+- This is the null-terminated index name.
+-
+-
+- - Function: struct if_nameindex * if_nameindex (void)
+- This function returns an array of `if_nameindex' structures, one
+- for every interface that is present. The end of the list is
+- indicated by a structure with an interface of 0 and a null name
+- pointer. If an error occurs, this function returns a null pointer.
+-
+- The returned structure must be freed with `if_freenameindex' after
+- use.
+-
+- - Function: void if_freenameindex (struct if_nameindex *ptr)
+- This function frees the structure returned by an earlier call to
+- `if_nameindex'.

+-The Local Namespace
+-===================
+-
+- This section describes the details of the local namespace, whose
+-symbolic name (required when you create a socket) is `PF_LOCAL'. The
+-local namespace is also known as "Unix domain sockets". Another name
+-is file namespace since socket addresses are normally implemented as
+-file names.

+-
+-Local Namespace Concepts
+-------------------------
+-
+- In the local namespace socket addresses are file names. You can
+-specify any file name you want as the address of the socket, but you
+-must have write permission on the directory containing it. It's common
+-to put these files in the `/tmp' directory.
+-
+- One peculiarity of the local namespace is that the name is only used
+-when opening the connection; once open the address is not meaningful and
+-may not exist.
+-
+- Another peculiarity is that you cannot connect to such a socket from
+-another machine-not even if the other machine shares the file system
+-which contains the name of the socket. You can see the socket in a
+-directory listing, but connecting to it never succeeds. Some programs
+-take advantage of this, such as by asking the client to send its own
+-process ID, and using the process IDs to distinguish between clients.
+-However, we recommend you not use this method in protocols you design,
+-as we might someday permit connections from other machines that mount
+-the same file systems. Instead, send each new client an identifying
+-number if you want it to have one.
+-
+- After you close a socket in the local namespace, you should delete
+-the file name from the file system. Use `unlink' or `remove' to do
+-this; see *Note Deleting Files::.
+-
+- The local namespace supports just one protocol for any communication
+-style; it is protocol number `0'.
+-
+-\1f
+-File: libc.info, Node: Local Namespace Details, Next: Local Socket Example, Prev: Local Namespace Concepts, Up: Local Namespace
+-
+-Details of Local Namespace
+---------------------------
+-
+- To create a socket in the local namespace, use the constant
+-`PF_LOCAL' as the NAMESPACE argument to `socket' or `socketpair'. This
+-constant is defined in `sys/socket.h'.
+-
+- - Macro: int PF_LOCAL
+- This designates the local namespace, in which socket addresses are
+- local names, and its associated family of protocols. `PF_Local'
+- is the macro used by Posix.1g.
+-
+- - Macro: int PF_UNIX
+- This is a synonym for `PF_LOCAL', for compatibility's sake.
+-
+- - Macro: int PF_FILE
+- This is a synonym for `PF_LOCAL', for compatibility's sake.
+-
+- The structure for specifying socket names in the local namespace is
+-defined in the header file `sys/un.h':
+-
+- - Data Type: struct sockaddr_un
+- This structure is used to specify local namespace socket
+- addresses. It has the following members:
+-
+- `short int sun_family'
+- This identifies the address family or format of the socket
+- address. You should store the value `AF_LOCAL' to designate
+- the local namespace. *Note Socket Addresses::.
+-
+- `char sun_path[108]'
+- This is the file name to use.
+-
+- *Incomplete:* Why is 108 a magic number? RMS suggests making
+- this a zero-length array and tweaking the following example
+- to use `alloca' to allocate an appropriate amount of storage
+- based on the length of the filename.
+-
+- You should compute the LENGTH parameter for a socket address in the
+-local namespace as the sum of the size of the `sun_family' component
+-and the string length (_not_ the allocation size!) of the file name
+-string. This can be done using the macro `SUN_LEN':
+-
+- - Macro: int SUN_LEN (_struct sockaddr_un *_ PTR)
+- The macro computes the length of socket address in the local
+- namespace.

+-The Internet Namespace
+-======================
+-
+- This section describes the details of the protocols and socket naming
+-conventions used in the Internet namespace.
+-
+- Originally the Internet namespace used only IP version 4 (IPv4).
+-With the growing number of hosts on the Internet, a new protocol with a
+-larger address space was necessary: IP version 6 (IPv6). IPv6
+-introduces 128-bit addresses (IPv4 has 32-bit addresses) and other
+-features, and will eventually replace IPv4.
+-
+- To create a socket in the IPv4 Internet namespace, use the symbolic
+-name `PF_INET' of this namespace as the NAMESPACE argument to `socket'
+-or `socketpair'. For IPv6 addresses you need the macro `PF_INET6'.
+-These macros are defined in `sys/socket.h'.
+-
+- - Macro: int PF_INET
+- This designates the IPv4 Internet namespace and associated family
+- of protocols.
+-
+- - Macro: int PF_INET6
+- This designates the IPv6 Internet namespace and associated family
+- of protocols.
+-
+- A socket address for the Internet namespace includes the following
+-components:
+-
+- * The address of the machine you want to connect to. Internet
+- addresses can be specified in several ways; these are discussed in
+- *Note Internet Address Formats::, *Note Host Addresses:: and *Note
+- Host Names::.
+-
+- * A port number for that machine. *Note Ports::.
+-
+- You must ensure that the address and port number are represented in a
+-canonical format called "network byte order". *Note Byte Order::, for

+-Internet Socket Address Formats
+--------------------------------
+-
+- In the Internet namespace, for both IPv4 (`AF_INET') and IPv6
+-(`AF_INET6'), a socket address consists of a host address and a port on
+-that host. In addition, the protocol you choose serves effectively as
+-a part of the address because local port numbers are meaningful only
+-within a particular protocol.
+-
+- The data types for representing socket addresses in the Internet
+-namespace are defined in the header file `netinet/in.h'.
+-
+- - Data Type: struct sockaddr_in
+- This is the data type used to represent socket addresses in the
+- Internet namespace. It has the following members:
+-
+- `sa_family_t sin_family'
+- This identifies the address family or format of the socket
+- address. You should store the value `AF_INET' in this member.
+- *Note Socket Addresses::.
+-
+- `struct in_addr sin_addr'
+- This is the Internet address of the host machine. *Note Host
+- Addresses::, and *Note Host Names::, for how to get a value
+- to store here.
+-
+- `unsigned short int sin_port'
+- This is the port number. *Note Ports::.
+-
+- When you call `bind' or `getsockname', you should specify `sizeof
+-(struct sockaddr_in)' as the LENGTH parameter if you are using an IPv4
+-Internet namespace socket address.
+-
+- - Data Type: struct sockaddr_in6
+- This is the data type used to represent socket addresses in the
+- IPv6 namespace. It has the following members:
+-
+- `sa_family_t sin6_family'
+- This identifies the address family or format of the socket
+- address. You should store the value of `AF_INET6' in this
+- member. *Note Socket Addresses::.
+-
+- `struct in6_addr sin6_addr'
+- This is the IPv6 address of the host machine. *Note Host
+- Addresses::, and *Note Host Names::, for how to get a value
+- to store here.
+-
+- `uint32_t sin6_flowinfo'

+-Host Addresses
+---------------
+-
+- Each computer on the Internet has one or more "Internet addresses",
+-numbers which identify that computer among all those on the Internet.
+-Users typically write IPv4 numeric host addresses as sequences of four
+-numbers, separated by periods, as in `128.52.46.32', and IPv6 numeric
+-host addresses as sequences of up to eight numbers separated by colons,
+-as in `5f03:1200:836f:c100::1'.
+-
+- Each computer also has one or more "host names", which are strings
+-of words separated by periods, as in `mescaline.gnu.org'.
+-
+- Programs that let the user specify a host typically accept both
+-numeric addresses and host names. To open a connection a program needs
+-a numeric address, and so must convert a host name to the numeric
+-address it stands for.

+-Internet Host Addresses
+-.......................
+-
+- Each computer on the Internet has one or more Internet addresses,
+-numbers which identify that computer among all those on the Internet.
+-
+- An IPv4 Internet host address is a number containing four bytes of
+-data. Historically these are divided into two parts, a "network
+-number" and a "local network address number" within that network. In
+-the mid-1990s classless addresses were introduced which changed this
+-behavior. Since some functions implicitly expect the old definitions,
+-we first describe the class-based network and will then describe
+-classless addresses. IPv6 uses only classless addresses and therefore
+-the following paragraphs don't apply.
+-
+- The class-based IPv4 network number consists of the first one, two or
+-three bytes; the rest of the bytes are the local address.
+-
+- IPv4 network numbers are registered with the Network Information
+-Center (NIC), and are divided into three classes--A, B and C. The local
+-network address numbers of individual machines are registered with the
+-administrator of the particular network.
+-
+- Class A networks have single-byte numbers in the range 0 to 127.
+-There are only a small number of Class A networks, but they can each
+-support a very large number of hosts. Medium-sized Class B networks
+-have two-byte network numbers, with the first byte in the range 128 to
+-191. Class C networks are the smallest; they have three-byte network
+-numbers, with the first byte in the range 192-255. Thus, the first 1,
+-2, or 3 bytes of an Internet address specify a network. The remaining
+-bytes of the Internet address specify the address within that network.
+-
+- The Class A network 0 is reserved for broadcast to all networks. In
+-addition, the host number 0 within each network is reserved for
+-broadcast to all hosts in that network. These uses are obsolete now
+-but for compatibility reasons you shouldn't use network 0 and host
+-number 0.
+-
+- The Class A network 127 is reserved for loopback; you can always use
+-the Internet address `127.0.0.1' to refer to the host machine.
+-
+- Since a single machine can be a member of multiple networks, it can
+-have multiple Internet host addresses. However, there is never
+-supposed to be more than one machine with the same host address.
+-
+- There are four forms of the "standard numbers-and-dots notation" for
+-Internet addresses:
+-
+-`A.B.C.D'
+- This specifies all four bytes of the address individually and is
+- the commonly used representation.
+-
+-`A.B.C'
+- The last part of the address, C, is interpreted as a 2-byte
+- quantity. This is useful for specifying host addresses in a Class
+- B network with network address number `A.B'.
+-
+-`A.B'
+- The last part of the address, B, is interpreted as a 3-byte
+- quantity. This is useful for specifying host addresses in a Class
+- A network with network address number A.
+-
+-`A'
+- If only one part is given, this corresponds directly to the host
+- address number.
+-
+- Within each part of the address, the usual C conventions for
+-specifying the radix apply. In other words, a leading `0x' or `0X'
+-implies hexadecimal radix; a leading `0' implies octal; and otherwise
+-decimal radix is assumed.
+-
+-Classless Addresses
+-...................
+-
+- IPv4 addresses (and IPv6 addresses also) are now considered
+-classless; the distinction between classes A, B and C can be ignored.
+-Instead an IPv4 host address consists of a 32-bit address and a 32-bit
+-mask. The mask contains set bits for the network part and cleared bits
+-for the host part. The network part is contiguous from the left, with
+-the remaining bits representing the host. As a consequence, the
+-netmask can simply be specified as the number of set bits. Classes A,
+-B and C are just special cases of this general rule. For example,
+-class A addresses have a netmask of `255.0.0.0' or a prefix length of 8.
+-
+- Classless IPv4 network addresses are written in numbers-and-dots
+-notation with the prefix length appended and a slash as separator. For
+-example the class A network 10 is written as `10.0.0.0/8'.
+-
+-IPv6 Addresses
+-..............
+-
+- IPv6 addresses contain 128 bits (IPv4 has 32 bits) of data. A host
+-address is usually written as eight 16-bit hexadecimal numbers that are
+-separated by colons. Two colons are used to abbreviate strings of
+-consecutive zeros. For example, the IPv6 loopback address
+-`0:0:0:0:0:0:0:1' can just be written as `::1'.

+-\1f
+-File: libc.info, Node: Host Address Data Type, Next: Host Address Functions, Prev: Abstract Host Addresses, Up: Host Addresses
+-
+-Host Address Data Type
+-......................
+-
+- IPv4 Internet host addresses are represented in some contexts as
+-integers (type `uint32_t'). In other contexts, the integer is packaged
+-inside a structure of type `struct in_addr'. It would be better if the
+-usage were made consistent, but it is not hard to extract the integer
+-from the structure or put the integer into a structure.
+-
+- You will find older code that uses `unsigned long int' for IPv4
+-Internet host addresses instead of `uint32_t' or `struct in_addr'.
+-Historically `unsigned long int' was a 32-bit number but with 64-bit
+-machines this has changed. Using `unsigned long int' might break the
+-code if it is used on machines where this type doesn't have 32 bits.
+-`uint32_t' is specified by Unix98 and guaranteed to have 32 bits.
+-
+- IPv6 Internet host addresses have 128 bits and are packaged inside a
+-structure of type `struct in6_addr'.
+-
+- The following basic definitions for Internet addresses are declared
+-in the header file `netinet/in.h':
+-
+- - Data Type: struct in_addr
+- This data type is used in certain contexts to contain an IPv4
+- Internet host address. It has just one field, named `s_addr',
+- which records the host address number as an `uint32_t'.
+-
+- - Macro: uint32_t INADDR_LOOPBACK
+- You can use this constant to stand for "the address of this
+- machine," instead of finding its actual address. It is the IPv4
+- Internet address `127.0.0.1', which is usually called `localhost'.
+- This special constant saves you the trouble of looking up the
+- address of your own machine. Also, the system usually implements
+- `INADDR_LOOPBACK' specially, avoiding any network traffic for the
+- case of one machine talking to itself.
+-
+- - Macro: uint32_t INADDR_ANY
+- You can use this constant to stand for "any incoming address" when
+- binding to an address. *Note Setting Address::. This is the usual
+- address to give in the `sin_addr' member of `struct sockaddr_in'
+- when you want to accept Internet connections.
+-
+- - Macro: uint32_t INADDR_BROADCAST
+- This constant is the address you use to send a broadcast message.
+-
+- - Macro: uint32_t INADDR_NONE
+- This constant is returned by some functions to indicate an error.
+-
+- - Data Type: struct in6_addr
+- This data type is used to store an IPv6 address. It stores 128
+- bits of data, which can be accessed (via a union) in a variety of
+- ways.
+-
+- - Constant: struct in6_addr in6addr_loopback
+- This constant is the IPv6 address `::1', the loopback address. See
+- above for a description of what this means. The macro
+- `IN6ADDR_LOOPBACK_INIT' is provided to allow you to initialize your
+- own variables to this value.
+-
+- - Constant: struct in6_addr in6addr_any
+- This constant is the IPv6 address `::', the unspecified address.
+- See above for a description of what this means. The macro
+- `IN6ADDR_ANY_INIT' is provided to allow you to initialize your own
+- variables to this value.

+-Host Address Functions
+-......................
+-
+-These additional functions for manipulating Internet addresses are
+-declared in the header file `arpa/inet.h'. They represent Internet
+-addresses in network byte order, and network numbers and
+-local-address-within-network numbers in host byte order. *Note Byte
+-Order::, for an explanation of network and host byte order.
+-
+- - Function: int inet_aton (const char *NAME, struct in_addr *ADDR)
+- This function converts the IPv4 Internet host address NAME from
+- the standard numbers-and-dots notation into binary data and stores
+- it in the `struct in_addr' that ADDR points to. `inet_aton'
+- returns nonzero if the address is valid, zero if not.
+-
+- - Function: uint32_t inet_addr (const char *NAME)
+- This function converts the IPv4 Internet host address NAME from the
+- standard numbers-and-dots notation into binary data. If the input
+- is not valid, `inet_addr' returns `INADDR_NONE'. This is an
+- obsolete interface to `inet_aton', described immediately above. It
+- is obsolete because `INADDR_NONE' is a valid address
+- (255.255.255.255), and `inet_aton' provides a cleaner way to
+- indicate error return.
+-
+- - Function: uint32_t inet_network (const char *NAME)
+- This function extracts the network number from the address NAME,
+- given in the standard numbers-and-dots notation. The returned
+- address is in host order. If the input is not valid,
+- `inet_network' returns `-1'.
+-
+- The function works only with traditional IPv4 class A, B and C
+- network types. It doesn't work with classless addresses and
+- shouldn't be used anymore.
+-
+- - Function: char * inet_ntoa (struct in_addr ADDR)
+- This function converts the IPv4 Internet host address ADDR to a
+- string in the standard numbers-and-dots notation. The return
+- value is a pointer into a statically-allocated buffer. Subsequent
+- calls will overwrite the same buffer, so you should copy the
+- string if you need to save it.
+-
+- In multi-threaded programs each thread has an own
+- statically-allocated buffer. But still subsequent calls of
+- `inet_ntoa' in the same thread will overwrite the result of the
+- last call.
+-
+- Instead of `inet_ntoa' the newer function `inet_ntop' which is
+- described below should be used since it handles both IPv4 and IPv6
+- addresses.
+-
+- - Function: struct in_addr inet_makeaddr (uint32_t NET, uint32_t LOCAL)
+- This function makes an IPv4 Internet host address by combining the
+- network number NET with the local-address-within-network number
+- LOCAL.
+-
+- - Function: uint32_t inet_lnaof (struct in_addr ADDR)
+- This function returns the local-address-within-network part of the
+- Internet host address ADDR.

+- This function returns the network number part of the Internet host
+- address ADDR.
+-
+- The function works only with traditional IPv4 class A, B and C
+- network types. It doesn't work with classless addresses and
+- shouldn't be used anymore.
+-
+- - Function: int inet_pton (int AF, const char *CP, void *BUF)
+- This function converts an Internet address (either IPv4 or IPv6)
+- from presentation (textual) to network (binary) format. AF should
+- be either `AF_INET' or `AF_INET6', as appropriate for the type of
+- address being converted. CP is a pointer to the input string, and
+- BUF is a pointer to a buffer for the result. It is the caller's
+- responsibility to make sure the buffer is large enough.
+-
+- - Function: const char * inet_ntop (int AF, const void *CP, char *BUF,
+- size_t LEN)
+- This function converts an Internet address (either IPv4 or IPv6)
+- from network (binary) to presentation (textual) form. AF should be
+- either `AF_INET' or `AF_INET6', as appropriate. CP is a pointer
+- to the address to be converted. BUF should be a pointer to a
+- buffer to hold the result, and LEN is the length of this buffer.
+- The return value from the function will be this buffer address.

+-Host Names
+-..........
+-
+- Besides the standard numbers-and-dots notation for Internet
+-addresses, you can also refer to a host by a symbolic name. The
+-advantage of a symbolic name is that it is usually easier to remember.
+-For example, the machine with Internet address `158.121.106.19' is also
+-known as `alpha.gnu.org'; and other machines in the `gnu.org' domain
+-can refer to it simply as `alpha'.
+-
+- Internally, the system uses a database to keep track of the mapping
+-between host names and host numbers. This database is usually either
+-the file `/etc/hosts' or an equivalent provided by a name server. The
+-functions and other symbols for accessing this database are declared in
+-`netdb.h'. They are BSD features, defined unconditionally if you
+-include `netdb.h'.
+-
+- - Data Type: struct hostent
+- This data type is used to represent an entry in the hosts
+- database. It has the following members:
+-
+- `char *h_name'
+- This is the "official" name of the host.
+-
+- `char **h_aliases'
+- These are alternative names for the host, represented as a
+- null-terminated vector of strings.
+-
+- `int h_addrtype'
+- This is the host address type; in practice, its value is
+- always either `AF_INET' or `AF_INET6', with the latter being
+- used for IPv6 hosts. In principle other kinds of addresses
+- could be represented in the database as well as Internet
+- addresses; if this were done, you might find a value in this
+- field other than `AF_INET' or `AF_INET6'. *Note Socket
+- Addresses::.
+-
+- `int h_length'
+- This is the length, in bytes, of each address.
+-
+- `char **h_addr_list'
+- This is the vector of addresses for the host. (Recall that
+- the host might be connected to multiple networks and have
+- different addresses on each one.) The vector is terminated
+- by a null pointer.
+-
+- `char *h_addr'
+- This is a synonym for `h_addr_list[0]'; in other words, it is
+- the first host address.
+-
+- As far as the host database is concerned, each address is just a
+-block of memory `h_length' bytes long. But in other contexts there is
+-an implicit assumption that you can convert IPv4 addresses to a `struct
+-in_addr' or an `uint32_t'. Host addresses in a `struct hostent'
+-structure are always given in network byte order; see *Note Byte
+-Order::.
+-
+- You can use `gethostbyname', `gethostbyname2' or `gethostbyaddr' to
+-search the hosts database for information about a particular host. The
+-information is returned in a statically-allocated structure; you must
+-copy the information if you need to save it across calls. You can also
+-use `getaddrinfo' and `getnameinfo' to obtain this information.
+-
+- - Function: struct hostent * gethostbyname (const char *NAME)
+- The `gethostbyname' function returns information about the host
+- named NAME. If the lookup fails, it returns a null pointer.
+-
+- - Function: struct hostent * gethostbyname2 (const char *NAME, int AF)
+- The `gethostbyname2' function is like `gethostbyname', but allows
+- the caller to specify the desired address family (e.g. `AF_INET'
+- or `AF_INET6') of the result.
+-
+- - Function: struct hostent * gethostbyaddr (const char *ADDR, size_t
+- LENGTH, int FORMAT)
+- The `gethostbyaddr' function returns information about the host
+- with Internet address ADDR. The parameter ADDR is not really a
+- pointer to char - it can be a pointer to an IPv4 or an IPv6
+- address. The LENGTH argument is the size (in bytes) of the address
+- at ADDR. FORMAT specifies the address format; for an IPv4
+- Internet address, specify a value of `AF_INET'; for an IPv6
+- Internet address, use `AF_INET6'.
+-
+- If the lookup fails, `gethostbyaddr' returns a null pointer.
+-
+- If the name lookup by `gethostbyname' or `gethostbyaddr' fails, you
+-can find out the reason by looking at the value of the variable
+-`h_errno'. (It would be cleaner design for these functions to set
+-`errno', but use of `h_errno' is compatible with other systems.)
+-
+- Here are the error codes that you may find in `h_errno':
+-
+-`HOST_NOT_FOUND'
+- No such host is known in the database.
+-
+-`TRY_AGAIN'
+- This condition happens when the name server could not be
+- contacted. If you try again later, you may succeed then.
+-
+-`NO_RECOVERY'
+- A non-recoverable error occurred.
+-
+-`NO_ADDRESS'
+- The host database contains an entry for the name, but it doesn't
+- have an associated Internet address.
+-
+- The lookup functions above all have one in common: they are not
+-reentrant and therefore unusable in multi-threaded applications.
+-Therefore provides the GNU C library a new set of functions which can be
+-used in this context.
+-
+- - Function: int gethostbyname_r (const char *restrict NAME, struct
+- hostent *restrict RESULT_BUF, char *restrict BUF, size_t
+- BUFLEN, struct hostent **restrict RESULT, int *restrict
+- H_ERRNOP)
+- The `gethostbyname_r' function returns information about the host
+- named NAME. The caller must pass a pointer to an object of type
+- `struct hostent' in the RESULT_BUF parameter. In addition the
+- function may need extra buffer space and the caller must pass an
+- pointer and the size of the buffer in the BUF and BUFLEN
+- parameters.
+-
+- A pointer to the buffer, in which the result is stored, is
+- available in `*RESULT' after the function call successfully
+- returned. If an error occurs or if no entry is found, the pointer
+- `*RESULT' is a null pointer. Success is signalled by a zero
+- return value. If the function failed the return value is an error
+- number. In addition to the errors defined for `gethostbyname' it
+- can also be `ERANGE'. In this case the call should be repeated
+- with a larger buffer. Additional error information is not stored
+- in the global variable `h_errno' but instead in the object pointed
+- to by H_ERRNOP.
+-
+- Here's a small example:
+- struct hostent *
+- gethostname (char *host)
+- {
+- struct hostent hostbuf, *hp;
+- size_t hstbuflen;
+- char *tmphstbuf;
+- int res;
+- int herr;
+-
+- hstbuflen = 1024;
+- /* Allocate buffer, remember to free it to avoid memory leakage. */
+- tmphstbuf = malloc (hstbuflen);
+-
+- while ((res = gethostbyname_r (host, &hostbuf, tmphstbuf, hstbuflen,
+- &hp, &herr)) == ERANGE)
+- {
+- /* Enlarge the buffer. */
+- hstbuflen *= 2;
+- tmphstbuf = realloc (tmphstbuf, hstbuflen);
+- }
+- /* Check for errors. */
+- if (res || hp == NULL)
+- return NULL;
+- return hp;
+- }
+-
+- - Function: int gethostbyname2_r (const char *NAME, int AF, struct
+- hostent *restrict RESULT_BUF, char *restrict BUF, size_t
+- BUFLEN, struct hostent **restrict RESULT, int *restrict
+- H_ERRNOP)
+- The `gethostbyname2_r' function is like `gethostbyname_r', but
+- allows the caller to specify the desired address family (e.g.
+- `AF_INET' or `AF_INET6') for the result.
+-
+- - Function: int gethostbyaddr_r (const char *ADDR, size_t LENGTH, int
+- FORMAT, struct hostent *restrict RESULT_BUF, char *restrict
+- BUF, size_t BUFLEN, struct hostent **restrict RESULT, int
+- *restrict H_ERRNOP)
+- The `gethostbyaddr_r' function returns information about the host
+- with Internet address ADDR. The parameter ADDR is not really a
+- pointer to char - it can be a pointer to an IPv4 or an IPv6
+- address. The LENGTH argument is the size (in bytes) of the address
+- at ADDR. FORMAT specifies the address format; for an IPv4
+- Internet address, specify a value of `AF_INET'; for an IPv6
+- Internet address, use `AF_INET6'.
+-
+- Similar to the `gethostbyname_r' function, the caller must provide
+- buffers for the result and memory used internally. In case of
+- success the function returns zero. Otherwise the value is an
+- error number where `ERANGE' has the special meaning that the
+- caller-provided buffer is too small.
+-
+- You can also scan the entire hosts database one entry at a time using
+-`sethostent', `gethostent' and `endhostent'. Be careful when using
+-these functions because they are not reentrant.
+-
+- - Function: void sethostent (int STAYOPEN)
+- This function opens the hosts database to begin scanning it. You
+- can then call `gethostent' to read the entries.
+-
+- If the STAYOPEN argument is nonzero, this sets a flag so that
+- subsequent calls to `gethostbyname' or `gethostbyaddr' will not
+- close the database (as they usually would). This makes for more
+- efficiency if you call those functions several times, by avoiding
+- reopening the database for each call.
+-
+- - Function: struct hostent * gethostent (void)
+- This function returns the next entry in the hosts database. It
+- returns a null pointer if there are no more entries.
+-
+- - Function: void endhostent (void)
+- This function closes the hosts database.

+-
+-Internet Ports
+---------------
+-
+- A socket address in the Internet namespace consists of a machine's
+-Internet address plus a "port number" which distinguishes the sockets
+-on a given machine (for a given protocol). Port numbers range from 0
+-to 65,535.
+-
+- Port numbers less than `IPPORT_RESERVED' are reserved for standard
+-servers, such as `finger' and `telnet'. There is a database that keeps
+-track of these, and you can use the `getservbyname' function to map a
+-service name onto a port number; see *Note Services Database::.
+-
+- If you write a server that is not one of the standard ones defined in
+-the database, you must choose a port number for it. Use a number
+-greater than `IPPORT_USERRESERVED'; such numbers are reserved for
+-servers and won't ever be generated automatically by the system.
+-Avoiding conflicts with servers being run by other users is up to you.
+-
+- When you use a socket without specifying its address, the system
+-generates a port number for it. This number is between
+-`IPPORT_RESERVED' and `IPPORT_USERRESERVED'.
+-
+- On the Internet, it is actually legitimate to have two different
+-sockets with the same port number, as long as they never both try to
+-communicate with the same socket address (host address plus port
+-number). You shouldn't duplicate a port number except in special
+-circumstances where a higher-level protocol requires it. Normally, the
+-system won't let you do it; `bind' normally insists on distinct port
+-numbers. To reuse a port number, you must set the socket option
+-`SO_REUSEADDR'. *Note Socket-Level Options::.
+-
+- These macros are defined in the header file `netinet/in.h'.
+-
+- - Macro: int IPPORT_RESERVED
+- Port numbers less than `IPPORT_RESERVED' are reserved for
+- superuser use.
+-
+- - Macro: int IPPORT_USERRESERVED
+- Port numbers greater than or equal to `IPPORT_USERRESERVED' are
+- reserved for explicit use; they will never be allocated
+- automatically.

+-The Services Database
+----------------------
+-
+- The database that keeps track of "well-known" services is usually
+-either the file `/etc/services' or an equivalent from a name server.
+-You can use these utilities, declared in `netdb.h', to access the
+-services database.
+-
+- - Data Type: struct servent
+- This data type holds information about entries from the services
+- database. It has the following members:
+-
+- `char *s_name'
+- This is the "official" name of the service.
+-
+- `char **s_aliases'
+- These are alternate names for the service, represented as an
+- array of strings. A null pointer terminates the array.
+-
+- `int s_port'
+- This is the port number for the service. Port numbers are
+- given in network byte order; see *Note Byte Order::.
+-
+- `char *s_proto'
+- This is the name of the protocol to use with this service.
+- *Note Protocols Database::.
+-
+- To get information about a particular service, use the
+-`getservbyname' or `getservbyport' functions. The information is
+-returned in a statically-allocated structure; you must copy the
+-information if you need to save it across calls.
+-
+- - Function: struct servent * getservbyname (const char *NAME, const
+- char *PROTO)
+- The `getservbyname' function returns information about the service
+- named NAME using protocol PROTO. If it can't find such a service,
+- it returns a null pointer.
+-
+- This function is useful for servers as well as for clients; servers
+- use it to determine which port they should listen on (*note
+- Listening::).
+-
+- - Function: struct servent * getservbyport (int PORT, const char
+- *PROTO)
+- The `getservbyport' function returns information about the service
+- at port PORT using protocol PROTO. If it can't find such a
+- service, it returns a null pointer.
+-
+-You can also scan the services database using `setservent',
+-`getservent' and `endservent'. Be careful when using these functions
+-because they are not reentrant.
+-
+- - Function: void setservent (int STAYOPEN)

+-Byte Order Conversion
+----------------------
+-
+- Different kinds of computers use different conventions for the
+-ordering of bytes within a word. Some computers put the most
+-significant byte within a word first (this is called "big-endian"
+-order), and others put it last ("little-endian" order).
+-
+- So that machines with different byte order conventions can
+-communicate, the Internet protocols specify a canonical byte order
+-convention for data transmitted over the network. This is known as
+-"network byte order".
+-
+- When establishing an Internet socket connection, you must make sure
+-that the data in the `sin_port' and `sin_addr' members of the
+-`sockaddr_in' structure are represented in network byte order. If you
+-are encoding integer data in the messages sent through the socket, you
+-should convert this to network byte order too. If you don't do this,
+-your program may fail when running on or talking to other kinds of
+-machines.
+-
+- If you use `getservbyname' and `gethostbyname' or `inet_addr' to get
+-the port number and host address, the values are already in network
+-byte order, and you can copy them directly into the `sockaddr_in'
+-structure.
+-
+- Otherwise, you have to convert the values explicitly. Use `htons'
+-and `ntohs' to convert values for the `sin_port' member. Use `htonl'
+-and `ntohl' to convert IPv4 addresses for the `sin_addr' member.
+-(Remember, `struct in_addr' is equivalent to `uint32_t'.) These
+-functions are declared in `netinet/in.h'.
+-
+- - Function: uint16_t htons (uint16_t HOSTSHORT)
+- This function converts the `uint16_t' integer HOSTSHORT from host
+- byte order to network byte order.
+-
+- - Function: uint16_t ntohs (uint16_t NETSHORT)
+- This function converts the `uint16_t' integer NETSHORT from
+- network byte order to host byte order.
+-
+- - Function: uint32_t htonl (uint32_t HOSTLONG)
+- This function converts the `uint32_t' integer HOSTLONG from host
+- byte order to network byte order.
+-
+- This is used for IPv4 Internet addresses.
+-
+- - Function: uint32_t ntohl (uint32_t NETLONG)
+- This function converts the `uint32_t' integer NETLONG from network
+- byte order to host byte order.
+-
+- This is used for IPv4 Internet addresses.

+-
+-Protocols Database
+-------------------
+-
+- The communications protocol used with a socket controls low-level
+-details of how data are exchanged. For example, the protocol implements
+-things like checksums to detect errors in transmissions, and routing
+-instructions for messages. Normal user programs have little reason to
+-mess with these details directly.
+-
+- The default communications protocol for the Internet namespace
+-depends on the communication style. For stream communication, the
+-default is TCP ("transmission control protocol"). For datagram
+-communication, the default is UDP ("user datagram protocol"). For
+-reliable datagram communication, the default is RDP ("reliable datagram
+-protocol"). You should nearly always use the default.
+-
+- Internet protocols are generally specified by a name instead of a
+-number. The network protocols that a host knows about are stored in a
+-database. This is usually either derived from the file
+-`/etc/protocols', or it may be an equivalent provided by a name server.
+-You look up the protocol number associated with a named protocol in
+-the database using the `getprotobyname' function.
+-
+- Here are detailed descriptions of the utilities for accessing the
+-protocols database. These are declared in `netdb.h'.
+-
+- - Data Type: struct protoent
+- This data type is used to represent entries in the network
+- protocols database. It has the following members:
+-
+- `char *p_name'
+- This is the official name of the protocol.
+-
+- `char **p_aliases'
+- These are alternate names for the protocol, specified as an
+- array of strings. The last element of the array is a null
+- pointer.
+-
+- `int p_proto'
+- This is the protocol number (in host byte order); use this
+- member as the PROTOCOL argument to `socket'.
+-
+- You can use `getprotobyname' and `getprotobynumber' to search the
+-protocols database for a specific protocol. The information is
+-returned in a statically-allocated structure; you must copy the
+-information if you need to save it across calls.
+-
+- - Function: struct protoent * getprotobyname (const char *NAME)
+- The `getprotobyname' function returns information about the
+- network protocol named NAME. If there is no such protocol, it
+- returns a null pointer.
+-
+- - Function: struct protoent * getprotobynumber (int PROTOCOL)
+- The `getprotobynumber' function returns information about the
+- network protocol with number PROTOCOL. If there is no such
+- protocol, it returns a null pointer.
+-
+- You can also scan the whole protocols database one protocol at a
+-time by using `setprotoent', `getprotoent' and `endprotoent'. Be
+-careful when using these functions because they are not reentrant.
+-
+- - Function: void setprotoent (int STAYOPEN)
+- This function opens the protocols database to begin scanning it.
+-
+- If the STAYOPEN argument is nonzero, this sets a flag so that
+- subsequent calls to `getprotobyname' or `getprotobynumber' will
+- not close the database (as they usually would). This makes for
+- more efficiency if you call those functions several times, by
+- avoiding reopening the database for each call.
+-
+- - Function: struct protoent * getprotoent (void)
+- This function returns the next entry in the protocols database. It
+- returns a null pointer if there are no more entries.

+-Internet Socket Example
+------------------------
+-
+- Here is an example showing how to create and name a socket in the
+-Internet namespace. The newly created socket exists on the machine that
+-the program is running on. Rather than finding and using the machine's
+-Internet address, this example specifies `INADDR_ANY' as the host
+-address; the system replaces that with the machine's actual address.
+-
+- #include <stdio.h>
+- #include <stdlib.h>
+- #include <sys/socket.h>
+- #include <netinet/in.h>
+-
+- int
+- make_socket (uint16_t port)
+- {
+- int sock;
+- struct sockaddr_in name;
+-
+- /* Create the socket. */
+- sock = socket (PF_INET, SOCK_STREAM, 0);
+- if (sock < 0)
+- {
+- perror ("socket");
+- exit (EXIT_FAILURE);
+- }
+-
+- /* Give the socket a name. */
+- name.sin_family = AF_INET;
+- name.sin_port = htons (port);
+- name.sin_addr.s_addr = htonl (INADDR_ANY);
+- if (bind (sock, (struct sockaddr *) &name, sizeof (name)) < 0)
+- {
+- perror ("bind");
+- exit (EXIT_FAILURE);
+- }
+-
+- return sock;
+- }
+-
+- Here is another example, showing how you can fill in a `sockaddr_in'

+- #include <stdlib.h>
+- #include <sys/socket.h>

+- `PF_INET' (*note Internet Namespace::). PROTOCOL designates the
+- specific protocol (*note Socket Concepts::); zero is usually right
+- for PROTOCOL.
+-
+- The return value from `socket' is the file descriptor for the new

+-Closing a Socket
+-----------------
+-
+- When you have finished using a socket, you can simply close its file
+-descriptor with `close'; see *Note Opening and Closing Files::. If
+-there is still data waiting to be transmitted over the connection,
+-normally `close' tries to complete this transmission. You can control
+-this behavior using the `SO_LINGER' socket option to specify a timeout
+-period; see *Note Socket Options::.
+-
+- You can also shut down only reception or transmission on a
+-connection by calling `shutdown', which is declared in `sys/socket.h'.
+-
+- - Function: int shutdown (int SOCKET, int HOW)
+- The `shutdown' function shuts down the connection of socket
+- SOCKET. The argument HOW specifies what action to perform:
+-
+- `0'
+- Stop receiving data for this socket. If further data arrives,
+- reject it.
+-
+- `1'
+- Stop trying to transmit data from this socket. Discard any
+- data waiting to be sent. Stop looking for acknowledgement of
+- data already sent; don't retransmit it if it is lost.
+-
+- `2'
+- Stop both reception and transmission.
+-
+- The return value is `0' on success and `-1' on failure. The
+- following `errno' error conditions are defined for this function:
+-
+- `EBADF'
+- SOCKET is not a valid file descriptor.

+-Socket Pairs
+-------------
+-
+- A "socket pair" consists of a pair of connected (but unnamed)
+-sockets. It is very similar to a pipe and is used in much the same
+-way. Socket pairs are created with the `socketpair' function, declared
+-in `sys/socket.h'. A socket pair is much like a pipe; the main
+-difference is that the socket pair is bidirectional, whereas the pipe
+-has one input-only end and one output-only end (*note Pipes and
+-FIFOs::).
+-
+- - Function: int socketpair (int NAMESPACE, int STYLE, int PROTOCOL,
+- int FILEDES[2])
+- This function creates a socket pair, returning the file
+- descriptors in `FILEDES[0]' and `FILEDES[1]'. The socket pair is
+- a full-duplex communications channel, so that both reading and
+- writing may be performed at either end.
+-
+- The NAMESPACE, STYLE and PROTOCOL arguments are interpreted as for
+- the `socket' function. STYLE should be one of the communication
+- styles listed in *Note Communication Styles::. The NAMESPACE
+- argument specifies the namespace, which must be `AF_LOCAL' (*note
+- Local Namespace::); PROTOCOL specifies the communications
+- protocol, but zero is the only meaningful value.
+-
+- If STYLE specifies a connectionless communication style, then the
+- two sockets you get are not _connected_, strictly speaking, but
+- each of them knows the other as the default destination address,
+- so they can send packets to each other.
+-
+- The `socketpair' function returns `0' on success and `-1' on
+- failure. The following `errno' error conditions are defined for
+- this function:
+-
+- `EMFILE'
+- The process has too many file descriptors open.
+-
+- `EAFNOSUPPORT'
+- The specified namespace is not supported.
+-

+- socket pairs.

+-Using Sockets with Connections
+-==============================
+-
+- The most common communication styles involve making a connection to a
+-particular other socket, and then exchanging data with that socket over
+-and over. Making a connection is asymmetric; one side (the "client")
+-acts to request a connection, while the other side (the "server") makes
+-a socket and waits for the connection request.

+-
+-Making a Connection
+--------------------
+-
+- In making a connection, the client makes a connection while the
+-server waits for and accepts the connection. Here we discuss what the
+-client program must do with the `connect' function, which is declared in
+-`sys/socket.h'.
+-
+- - Function: int connect (int SOCKET, struct sockaddr *ADDR, socklen_t
+- LENGTH)
+- The `connect' function initiates a connection from the socket with
+- file descriptor SOCKET to the socket whose address is specified by
+- the ADDR and LENGTH arguments. (This socket is typically on
+- another machine, and it must be already set up as a server.)
+- *Note Socket Addresses::, for information about how these
+- arguments are interpreted.
+-
+- Normally, `connect' waits until the server responds to the request
+- before it returns. You can set nonblocking mode on the socket
+- SOCKET to make `connect' return immediately without waiting for
+- the response. *Note File Status Flags::, for information about
+- nonblocking mode.
+-
+- The normal return value from `connect' is `0'. If an error
+- occurs, `connect' returns `-1'. The following `errno' error
+- conditions are defined for this function:
+-
+- `EBADF'
+- The socket SOCKET is not a valid file descriptor.
+-
+- `ENOTSOCK'
+- File descriptor SOCKET is not a socket.
+-
+- `EADDRNOTAVAIL'
+- The specified address is not available on the remote machine.
+-
+- `EAFNOSUPPORT'
+- The namespace of the ADDR is not supported by this socket.
+-
+- `EISCONN'
+- The socket SOCKET is already connected.
+-
+- `ETIMEDOUT'
+- The attempt to establish the connection timed out.
+-
+- `ECONNREFUSED'
+- The server has actively refused to establish the connection.
+-
+- `ENETUNREACH'
+- The network of the given ADDR isn't reachable from this host.
+-
+- `EADDRINUSE'
+- The socket address of the given ADDR is already in use.
+-
+- `EINPROGRESS'
+- The socket SOCKET is non-blocking and the connection could
+- not be established immediately. You can determine when the
+- connection is completely established with `select'; *note
+- Waiting for I/O::. Another `connect' call on the same
+- socket, before the connection is completely established, will
+- fail with `EALREADY'.
+-
+- `EALREADY'
+- The socket SOCKET is non-blocking and already has a pending
+- connection in progress (see `EINPROGRESS' above).
+-
+- This function is defined as a cancellation point in multi-threaded
+- programs, so one has to be prepared for this and make sure that
+- allocated resources (like memory, files descriptors, semaphores or
+- whatever) are freed even if the thread is canceled.

+-File: libc.info, Node: Listening, Next: Accepting Connections, Prev: Connecting, Up: Connections
+-
+-Listening for Connections
+--------------------------
+-
+- Now let us consider what the server process must do to accept
+-connections on a socket. First it must use the `listen' function to
+-enable connection requests on the socket, and then accept each incoming
+-connection with a call to `accept' (*note Accepting Connections::).
+-Once connection requests are enabled on a server socket, the `select'
+-function reports when the socket has a connection ready to be accepted
+-(*note Waiting for I/O::).
+-
+- The `listen' function is not allowed for sockets using
+-connectionless communication styles.
+-
+- You can write a network server that does not even start running
+-until a connection to it is requested. *Note Inetd Servers::.
+-
+- In the Internet namespace, there are no special protection mechanisms
+-for controlling access to a port; any process on any machine can make a
+-connection to your server. If you want to restrict access to your
+-server, make it examine the addresses associated with connection
+-requests or implement some other handshaking or identification protocol.
+-
+- In the local namespace, the ordinary file protection bits control
+-who has access to connect to the socket.
+-
+- - Function: int listen (int SOCKET, unsigned int N)
+- The `listen' function enables the socket SOCKET to accept
+- connections, thus making it a server socket.
+-
+- The argument N specifies the length of the queue for pending
+- connections. When the queue fills, new clients attempting to
+- connect fail with `ECONNREFUSED' until the server calls `accept' to
+- accept a connection from the queue.
+-
+- The `listen' function returns `0' on success and `-1' on failure.
+- The following `errno' error conditions are defined for this
+- function:
+-
+- `EBADF'
+- The argument SOCKET is not a valid file descriptor.
+-
+- `ENOTSOCK'
+- The argument SOCKET is not a socket.
+-
+- `EOPNOTSUPP'
+- The socket SOCKET does not support this operation.

+-File: libc.info, Node: Accepting Connections, Next: Who is Connected, Prev: Listening, Up: Connections
+-
+-Accepting Connections
+----------------------
+-
+- When a server receives a connection request, it can complete the
+-connection by accepting the request. Use the function `accept' to do
+-this.
+-
+- A socket that has been established as a server can accept connection
+-requests from multiple clients. The server's original socket _does not
+-become part of the connection_; instead, `accept' makes a new socket
+-which participates in the connection. `accept' returns the descriptor
+-for this socket. The server's original socket remains available for
+-listening for further connection requests.
+-
+- The number of pending connection requests on a server socket is
+-finite. If connection requests arrive from clients faster than the
+-server can act upon them, the queue can fill up and additional requests
+-are refused with an `ECONNREFUSED' error. You can specify the maximum
+-length of this queue as an argument to the `listen' function, although
+-the system may also impose its own internal limit on the length of this
+-queue.
+-
+- - Function: int accept (int SOCKET, struct sockaddr *ADDR, socklen_t
+- *LENGTH_PTR)
+- This function is used to accept a connection request on the server
+- socket SOCKET.
+-
+- The `accept' function waits if there are no connections pending,
+- unless the socket SOCKET has nonblocking mode set. (You can use
+- `select' to wait for a pending connection, with a nonblocking
+- socket.) *Note File Status Flags::, for information about
+- nonblocking mode.
+-
+- The ADDR and LENGTH-PTR arguments are used to return information
+- about the name of the client socket that initiated the connection.
+- *Note Socket Addresses::, for information about the format of the
+- information.
+-
+- Accepting a connection does not make SOCKET part of the
+- connection. Instead, it creates a new socket which becomes
+- connected. The normal return value of `accept' is the file
+- descriptor for the new socket.
+-
+- After `accept', the original socket SOCKET remains open and
+- unconnected, and continues listening until you close it. You can
+- accept further connections with SOCKET by calling `accept' again.
+-
+- If an error occurs, `accept' returns `-1'. The following `errno'
+- error conditions are defined for this function:
+-
+- `EBADF'
+- The SOCKET argument is not a valid file descriptor.
+-
+- `ENOTSOCK'
+- The descriptor SOCKET argument is not a socket.
+-
+- `EOPNOTSUPP'
+- The descriptor SOCKET does not support this operation.
+-
+- `EWOULDBLOCK'
+- SOCKET has nonblocking mode set, and there are no pending
+- connections immediately available.
+-
+- This function is defined as a cancellation point in multi-threaded
+- programs, so one has to be prepared for this and make sure that
+- allocated resources (like memory, files descriptors, semaphores or
+- whatever) are freed even if the thread is canceled.

+-Transferring Data
+------------------
+-
+- Once a socket has been connected to a peer, you can use the ordinary
+-`read' and `write' operations (*note I/O Primitives::) to transfer
+-data. A socket is a two-way communications channel, so read and write
+-operations can be performed at either end.
+-
+- There are also some I/O modes that are specific to socket operations.
+-In order to specify these modes, you must use the `recv' and `send'
+-functions instead of the more generic `read' and `write' functions.
+-The `recv' and `send' functions take an additional argument which you
+-can use to specify various flags to control special I/O modes. For
+-example, you can specify the `MSG_OOB' flag to read or write
+-out-of-band data, the `MSG_PEEK' flag to peek at input, or the
+-`MSG_DONTROUTE' flag to control inclusion of routing information on
+-output.

+-Out-of-Band Data
+-----------------
+-
+- Streams with connections permit "out-of-band" data that is delivered
+-with higher priority than ordinary data. Typically the reason for
+-sending out-of-band data is to send notice of an exceptional condition.
+-To send out-of-band data use `send', specifying the flag `MSG_OOB'
+-(*note Sending Data::).
+-
+- Out-of-band data are received with higher priority because the
+-receiving process need not read it in sequence; to read the next
+-available out-of-band data, use `recv' with the `MSG_OOB' flag (*note
+-Receiving Data::). Ordinary read operations do not read out-of-band
+-data; they read only ordinary data.
+-
+- When a socket finds that out-of-band data are on their way, it sends
+-a `SIGURG' signal to the owner process or process group of the socket.
+-You can specify the owner using the `F_SETOWN' command to the `fcntl'
+-function; see *Note Interrupt Input::. You must also establish a
+-handler for this signal, as described in *Note Signal Handling::, in
+-order to take appropriate action such as reading the out-of-band data.
+-
+- Alternatively, you can test for pending out-of-band data, or wait
+-until there is out-of-band data, using the `select' function; it can
+-wait for an exceptional condition on the socket. *Note Waiting for
+-I/O::, for more information about `select'.
+-
+- Notification of out-of-band data (whether with `SIGURG' or with
+-`select') indicates that out-of-band data are on the way; the data may
+-not actually arrive until later. If you try to read the out-of-band
+-data before it arrives, `recv' fails with an `EWOULDBLOCK' error.
+-
+- Sending out-of-band data automatically places a "mark" in the stream
+-of ordinary data, showing where in the sequence the out-of-band data
+-"would have been". This is useful when the meaning of out-of-band data
+-is "cancel everything sent so far". Here is how you can test, in the
+-receiving process, whether any ordinary data was sent before the mark:
+-
+- success = ioctl (socket, SIOCATMARK, &atmark);
+-
+- The `integer' variable ATMARK is set to a nonzero value if the
+-socket's read pointer has reached the "mark".
+-
+- Here's a function to discard any ordinary data preceding the
+-out-of-band mark:
+-
+- int
+- discard_until_mark (int socket)
+- {
+- while (1)
+- {
+- /* This is not an arbitrary limit; any size will do. */
+- char buffer[1024];
+- int atmark, success;
+-
+- /* If we have reached the mark, return. */
+- success = ioctl (socket, SIOCATMARK, &atmark);
+- if (success < 0)
+- perror ("ioctl");
+- if (result)
+- return;
+-
+- /* Otherwise, read a bunch of ordinary data and discard it.
+- This is guaranteed not to read past the mark
+- if it starts before the mark. */
+- success = read (socket, buffer, sizeof buffer);
+- if (success < 0)
+- perror ("read");
+- }
+- }
+-
+- If you don't want to discard the ordinary data preceding the mark,
+-you may need to read some of it anyway, to make room in internal system
+-buffers for the out-of-band data. If you try to read out-of-band data
+-and get an `EWOULDBLOCK' error, try reading some ordinary data (saving
+-it so that you can use it when you want it) and see if that makes room.
+-Here is an example:
+-
+- struct buffer
+- {
+- char *buf;
+- int size;
+- struct buffer *next;
+- };
+-
+- /* Read the out-of-band data from SOCKET and return it
+- as a `struct buffer', which records the address of the data
+- and its size.
+-
+- It may be necessary to read some ordinary data
+- in order to make room for the out-of-band data.
+- If so, the ordinary data are saved as a chain of buffers
+- found in the `next' field of the value. */
+-
+- struct buffer *
+- read_oob (int socket)
+- {
+- struct buffer *tail = 0;
+- struct buffer *list = 0;
+-
+- while (1)

+- /* This is an arbitrary limit.

+-Datagram Socket Operations
+-==========================
+-
+- This section describes how to use communication styles that don't use
+-connections (styles `SOCK_DGRAM' and `SOCK_RDM'). Using these styles,
+-you group data into packets and each packet is an independent
+-communication. You specify the destination for each packet
+-individually.
+-
+- Datagram packets are like letters: you send each one independently
+-with its own destination address, and they may arrive in the wrong
+-order or not at all.
+-
+- The `listen' and `accept' functions are not allowed for sockets
+-using connectionless communication styles.
+-
+-* Menu:
+-
+-* Sending Datagrams:: Sending packets on a datagram socket.
+-* Receiving Datagrams:: Receiving packets on a datagram socket.
+-* Datagram Example:: An example program: packets sent over a
+- datagram socket in the local namespace.
+-* Example Receiver:: Another program, that receives those packets.
+-
+-\1f
+-File: libc.info, Node: Sending Datagrams, Next: Receiving Datagrams, Up: Datagrams
+-
+-Sending Datagrams
+------------------
+-
+- The normal way of sending data on a datagram socket is by using the
+-`sendto' function, declared in `sys/socket.h'.
+-
+- You can call `connect' on a datagram socket, but this only specifies
+-a default destination for further data transmission on the socket.
+-When a socket has a default destination you can use `send' (*note
+-Sending Data::) or even `write' (*note I/O Primitives::) to send a
+-packet there. You can cancel the default destination by calling
+-`connect' using an address format of `AF_UNSPEC' in the ADDR argument.
+-*Note Connecting::, for more information about the `connect' function.
+-
+- - Function: int sendto (int SOCKET, void *BUFFER. size_t SIZE, int
+- FLAGS, struct sockaddr *ADDR, socklen_t LENGTH)
+- The `sendto' function transmits the data in the BUFFER through the
+- socket SOCKET to the destination address specified by the ADDR and
+- LENGTH arguments. The SIZE argument specifies the number of bytes
+- to be transmitted.
+-
+- The FLAGS are interpreted the same way as for `send'; see *Note
+- Socket Data Options::.
+-
+- The return value and error conditions are also the same as for
+- `send', but you cannot rely on the system to detect errors and
+- report them; the most common error is that the packet is lost or
+- there is no-one at the specified address to receive it, and the
+- operating system on your machine usually does not know this.
+-
+- It is also possible for one call to `sendto' to report an error
+- owing to a problem related to a previous call.
+-
+- This function is defined as a cancellation point in multi-threaded
+- programs, so one has to be prepared for this and make sure that
+- allocated resources (like memory, files descriptors, semaphores or
+- whatever) are freed even if the thread is canceled.
+-
+-\1f
+-File: libc.info, Node: Receiving Datagrams, Next: Datagram Example, Prev: Sending Datagrams, Up: Datagrams
+-
+-Receiving Datagrams
+--------------------
+-
+- The `recvfrom' function reads a packet from a datagram socket and
+-also tells you where it was sent from. This function is declared in
+-`sys/socket.h'.
+-
+- - Function: int recvfrom (int SOCKET, void *BUFFER, size_t SIZE, int
+- FLAGS, struct sockaddr *ADDR, socklen_t *LENGTH-PTR)
+- The `recvfrom' function reads one packet from the socket SOCKET
+- into the buffer BUFFER. The SIZE argument specifies the maximum
+- number of bytes to be read.
+-
+- If the packet is longer than SIZE bytes, then you get the first
+- SIZE bytes of the packet and the rest of the packet is lost.
+- There's no way to read the rest of the packet. Thus, when you use
+- a packet protocol, you must always know how long a packet to
+- expect.
+-
+- The ADDR and LENGTH-PTR arguments are used to return the address
+- where the packet came from. *Note Socket Addresses::. For a
+- socket in the local domain the address information won't be
+- meaningful, since you can't read the address of such a socket
+- (*note Local Namespace::). You can specify a null pointer as the
+- ADDR argument if you are not interested in this information.
+-
+- The FLAGS are interpreted the same way as for `recv' (*note Socket
+- Data Options::). The return value and error conditions are also
+- the same as for `recv'.
+-
+- This function is defined as a cancellation point in multi-threaded
+- programs, so one has to be prepared for this and make sure that
+- allocated resources (like memory, files descriptors, semaphores or
+- whatever) are freed even if the thread is canceled.
+-
+- You can use plain `recv' (*note Receiving Data::) instead of
+-`recvfrom' if you don't need to find out who sent the packet (either
+-because you know where it should come from or because you treat all
+-possible senders alike). Even `read' can be used if you don't want to
+-specify FLAGS (*note I/O Primitives::).

+-Datagram Socket Example
+------------------------
+-
+- Here is a set of example programs that send messages over a datagram
+-stream in the local namespace. Both the client and server programs use
+-the `make_named_socket' function that was presented in *Note Local
+-Socket Example::, to create and name their sockets.
+-
+- First, here is the server program. It sits in a loop waiting for
+-messages to arrive, bouncing each message back to the sender.

+-
+-Example of Reading Datagrams
+-----------------------------
+-
+- Here is the client program corresponding to the server above.
+-
+- It sends a datagram to the server and then waits for a reply. Notice
+-that the socket for the client (as well as for the server) in this
+-example has to be given a name. This is so that the server can direct
+-a message back to the client. Since the socket has no associated
+-connection state, the only way the server can do this is by referencing
+-the name of the client.
+-
+- #include <stdio.h>
+- #include <errno.h>
+- #include <unistd.h>
+- #include <stdlib.h>
+- #include <sys/socket.h>
+- #include <sys/un.h>
+-
+- #define SERVER "/tmp/serversocket"
+- #define CLIENT "/tmp/mysocket"
+- #define MAXMSG 512
+- #define MESSAGE "Yow!!! Are we having fun yet?!?"
+-
+- int
+- main (void)
+- {
+- extern int make_named_socket (const char *name);
+- int sock;
+- char message[MAXMSG];
+- struct sockaddr_un name;
+- size_t size;
+- int nbytes;
+-
+- /* Make the socket. */
+- sock = make_named_socket (CLIENT);
+-
+- /* Initialize the server socket address. */
+- name.sun_family = AF_LOCAL;
+- strcpy (name.sun_path, SERVER);
+- size = strlen (name.sun_path) + sizeof (name.sun_family);
+-
+- /* Send the datagram. */
+- nbytes = sendto (sock, MESSAGE, strlen (MESSAGE) + 1, 0,
+- (struct sockaddr *) & name, size);
+- if (nbytes < 0)
+- {
+- perror ("sendto (client)");
+- exit (EXIT_FAILURE);
+- }
+-
+- /* Wait for a reply. */
+- nbytes = recvfrom (sock, message, MAXMSG, 0, NULL, 0);
+- if (nbytes < 0)
+- {
+- perror ("recfrom (client)");
+- exit (EXIT_FAILURE);
+- }
+-
+- /* Print a diagnostic message. */
+- fprintf (stderr, "Client: got message: %s\n", message);
+-
+- /* Clean up. */
+- remove (CLIENT);
+- close (sock);
+- }
+-
+- Keep in mind that datagram socket communications are unreliable. In
+-this example, the client program waits indefinitely if the message
+-never reaches the server or if the server's response never comes back.
+-It's up to the user running the program to kill and restart it if
+-desired. A more automatic solution could be to use `select' (*note
+-Waiting for I/O::) to establish a timeout period for the reply, and in
+-case of timeout either re-send the message or shut down the socket and
+-exit.

+-
+-The `inetd' Daemon
+-==================
+-
+- We've explained above how to write a server program that does its own
+-listening. Such a server must already be running in order for anyone
+-to connect to it.
+-
+- Another way to provide a service on an Internet port is to let the
+-daemon program `inetd' do the listening. `inetd' is a program that
+-runs all the time and waits (using `select') for messages on a
+-specified set of ports. When it receives a message, it accepts the
+-connection (if the socket style calls for connections) and then forks a
+-child process to run the corresponding server program. You specify the
+-ports and their programs in the file `/etc/inetd.conf'.
+-
+-* Menu:
+-
+-* Inetd Servers::
+-* Configuring Inetd::
+-
+-\1f
+-File: libc.info, Node: Inetd Servers, Next: Configuring Inetd, Up: Inetd
+-
+-`inetd' Servers
+----------------
+-
+- Writing a server program to be run by `inetd' is very simple. Each
+-time someone requests a connection to the appropriate port, a new server
+-process starts. The connection already exists at this time; the socket
+-is available as the standard input descriptor and as the standard
+-output descriptor (descriptors 0 and 1) in the server process. Thus
+-the server program can begin reading and writing data right away.
+-Often the program needs only the ordinary I/O facilities; in fact, a
+-general-purpose filter program that knows nothing about sockets can
+-work as a byte stream server run by `inetd'.
+-
+- You can also use `inetd' for servers that use connectionless
+-communication styles. For these servers, `inetd' does not try to accept
+-a connection since no connection is possible. It just starts the
+-server program, which can read the incoming datagram packet from
+-descriptor 0. The server program can handle one request and then exit,
+-or you can choose to write it to keep reading more requests until no
+-more arrive, and then exit. You must specify which of these two
+-techniques the server uses when you configure `inetd'.
+-
+-\1f
+-File: libc.info, Node: Configuring Inetd, Prev: Inetd Servers, Up: Inetd
+-
+-Configuring `inetd'
+--------------------
+-
+- The file `/etc/inetd.conf' tells `inetd' which ports to listen to
+-and what server programs to run for them. Normally each entry in the
+-file is one line, but you can split it onto multiple lines provided all
+-but the first line of the entry start with whitespace. Lines that
+-start with `#' are comments.
+-
+- Here are two standard entries in `/etc/inetd.conf':
+-
+- ftp stream tcp nowait root /libexec/ftpd ftpd
+- talk dgram udp wait root /libexec/talkd talkd
+-
+- An entry has this format:
+-
+- SERVICE STYLE PROTOCOL WAIT USERNAME PROGRAM ARGUMENTS
+-
+- The SERVICE field says which service this program provides. It
+-should be the name of a service defined in `/etc/services'. `inetd'
+-uses SERVICE to decide which port to listen on for this entry.
+-
+- The fields STYLE and PROTOCOL specify the communication style and
+-the protocol to use for the listening socket. The style should be the
+-name of a communication style, converted to lower case and with `SOCK_'
+-deleted--for example, `stream' or `dgram'. PROTOCOL should be one of
+-the protocols listed in `/etc/protocols'. The typical protocol names
+-are `tcp' for byte stream connections and `udp' for unreliable
+-datagrams.
+-
+- The WAIT field should be either `wait' or `nowait'. Use `wait' if
+-STYLE is a connectionless style and the server, once started, handles
+-multiple requests as they come in. Use `nowait' if `inetd' should
+-start a new process for each message or request that comes in. If
+-STYLE uses connections, then WAIT *must* be `nowait'.
+-
+- USER is the user name that the server should run as. `inetd' runs
+-as root, so it can set the user ID of its children arbitrarily. It's
+-best to avoid using `root' for USER if you can; but some servers, such
+-as Telnet and FTP, read a username and password themselves. These
+-servers need to be root initially so they can log in as commanded by
+-the data coming over the network.
+-
+- PROGRAM together with ARGUMENTS specifies the command to run to
+-start the server. PROGRAM should be an absolute file name specifying
+-the executable file to run. ARGUMENTS consists of any number of
+-whitespace-separated words, which become the command-line arguments of
+-PROGRAM. The first word in ARGUMENTS is argument zero, which should by
+-convention be the program name itself (sans directories).
+-
+- If you edit `/etc/inetd.conf', you can tell `inetd' to reread the
+-file and obey its new contents by sending the `inetd' process the
+-`SIGHUP' signal. You'll have to use `ps' to determine the process ID
+-of the `inetd' process as it is not fixed.

+-Socket Option Functions
+------------------------
+-
+- Here are the functions for examining and modifying socket options.
+-They are declared in `sys/socket.h'.
+-
+- - Function: int getsockopt (int SOCKET, int LEVEL, int OPTNAME, void
+- *OPTVAL, socklen_t *OPTLEN-PTR)
+- The `getsockopt' function gets information about the value of
+- option OPTNAME at level LEVEL for socket SOCKET.
+-
+- The option value is stored in a buffer that OPTVAL points to.
+- Before the call, you should supply in `*OPTLEN-PTR' the size of
+- this buffer; on return, it contains the number of bytes of
+- information actually stored in the buffer.
+-
+- Most options interpret the OPTVAL buffer as a single `int' value.
+-
+- The actual return value of `getsockopt' is `0' on success and `-1'
+- on failure. The following `errno' error conditions are defined:
+-
+- `EBADF'
+- The SOCKET argument is not a valid file descriptor.
+-
+- `ENOTSOCK'
+- The descriptor SOCKET is not a socket.
+-
+- `ENOPROTOOPT'
+- The OPTNAME doesn't make sense for the given LEVEL.
+-
+- - Function: int setsockopt (int SOCKET, int LEVEL, int OPTNAME, void
+- *OPTVAL, socklen_t OPTLEN)
+- This function is used to set the socket option OPTNAME at level
+- LEVEL for socket SOCKET. The value of the option is passed in the
+- buffer OPTVAL of size OPTLEN.
+-
+- The return value and error codes for `setsockopt' are the same as
+- for `getsockopt'.

+-
+-Socket-Level Options
+---------------------
+-
+- - Constant: int SOL_SOCKET
+- Use this constant as the LEVEL argument to `getsockopt' or
+- `setsockopt' to manipulate the socket-level options described in
+- this section.
+-
+-Here is a table of socket-level option names; all are defined in the
+-header file `sys/socket.h'.
+-
+-`SO_DEBUG'
+- This option toggles recording of debugging information in the
+- underlying protocol modules. The value has type `int'; a nonzero
+- value means "yes".
+-
+-`SO_REUSEADDR'
+- This option controls whether `bind' (*note Setting Address::)
+- should permit reuse of local addresses for this socket. If you
+- enable this option, you can actually have two sockets with the
+- same Internet port number; but the system won't allow you to use
+- the two identically-named sockets in a way that would confuse the
+- Internet. The reason for this option is that some higher-level
+- Internet protocols, including FTP, require you to keep reusing the
+- same port number.
+-
+- The value has type `int'; a nonzero value means "yes".
+-
+-`SO_KEEPALIVE'
+- This option controls whether the underlying protocol should
+- periodically transmit messages on a connected socket. If the peer
+- fails to respond to these messages, the connection is considered
+- broken. The value has type `int'; a nonzero value means "yes".
+-
+-`SO_DONTROUTE'
+- This option controls whether outgoing messages bypass the normal
+- message routing facilities. If set, messages are sent directly to
+- the network interface instead. The value has type `int'; a nonzero
+- value means "yes".
+-
+-`SO_LINGER'
+- This option specifies what should happen when the socket of a type
+- that promises reliable delivery still has untransmitted messages
+- when it is closed; see *Note Closing a Socket::. The value has
+- type `struct linger'.
+-
+- - Data Type: struct linger
+- This structure type has the following members:
+-
+- `int l_onoff'
+- This field is interpreted as a boolean. If nonzero,
+- `close' blocks until the data are transmitted or the
+- timeout period has expired.
+-
+- `int l_linger'
+- This specifies the timeout period, in seconds.
+-
+-`SO_BROADCAST'
+- This option controls whether datagrams may be broadcast from the
+- socket. The value has type `int'; a nonzero value means "yes".
+-
+-`SO_OOBINLINE'
+- If this option is set, out-of-band data received on the socket is
+- placed in the normal input queue. This permits it to be read using
+- `read' or `recv' without specifying the `MSG_OOB' flag. *Note
+- Out-of-Band Data::. The value has type `int'; a nonzero value
+- means "yes".
+-
+-`SO_SNDBUF'
+- This option gets or sets the size of the output buffer. The value
+- is a `size_t', which is the size in bytes.
+-
+-`SO_RCVBUF'
+- This option gets or sets the size of the input buffer. The value
+- is a `size_t', which is the size in bytes.
+-
+-`SO_STYLE'
+-`SO_TYPE'
+- This option can be used with `getsockopt' only. It is used to get
+- the socket's communication style. `SO_TYPE' is the historical
+- name, and `SO_STYLE' is the preferred name in GNU. The value has
+- type `int' and its value designates a communication style; see
+- *Note Communication Styles::.
+-
+-`SO_ERROR'
+- This option can be used with `getsockopt' only. It is used to
+- reset the error status of the socket. The value is an `int',
+- which represents the previous error status.

+-Networks Database
+-=================
+-
+- Many systems come with a database that records a list of networks
+-known to the system developer. This is usually kept either in the file
+-`/etc/networks' or in an equivalent from a name server. This data base
+-is useful for routing programs such as `route', but it is not useful
+-for programs that simply communicate over the network. We provide
+-functions to access this database, which are declared in `netdb.h'.
+-
+- - Data Type: struct netent
+- This data type is used to represent information about entries in
+- the networks database. It has the following members:
+-
+- `char *n_name'
+- This is the "official" name of the network.
+-
+- `char **n_aliases'
+- These are alternative names for the network, represented as a
+- vector of strings. A null pointer terminates the array.
+-
+- `int n_addrtype'
+- This is the type of the network number; this is always equal
+- to `AF_INET' for Internet networks.
+-

+-Identifying Terminals
+-=====================
+-
+- The functions described in this chapter only work on files that
+-correspond to terminal devices. You can find out whether a file
+-descriptor is associated with a terminal by using the `isatty' function.
+-
+- Prototypes for the functions in this section are declared in the
+-header file `unistd.h'.
+-
+- - Function: int isatty (int FILEDES)
+- This function returns `1' if FILEDES is a file descriptor
+- associated with an open terminal device, and 0 otherwise.
+-
+- If a file descriptor is associated with a terminal, you can get its
+-associated file name using the `ttyname' function. See also the
+-`ctermid' function, described in *Note Identifying the Terminal::.
+-
+- - Function: char * ttyname (int FILEDES)
+- If the file descriptor FILEDES is associated with a terminal
+- device, the `ttyname' function returns a pointer to a
+- statically-allocated, null-terminated string containing the file
+- name of the terminal file. The value is a null pointer if the
+- file descriptor isn't associated with a terminal, or the file name
+- cannot be determined.
+-
+- - Function: int ttyname_r (int FILEDES, char *BUF, size_t LEN)
+- The `ttyname_r' function is similar to the `ttyname' function
+- except that it places its result into the user-specified buffer
+- starting at BUF with length LEN.
+-
+- The normal return value from `ttyname_r' is 0. Otherwise an error
+- number is returned to indicate the error. The following `errno'
+- error conditions are defined for this function:
+-
+- `EBADF'
+- The FILEDES argument is not a valid file descriptor.
+-
+- `ENOTTY'
+- The FILEDES is not associated with a terminal.
+-
+- `ERANGE'
+- The buffer length LEN is too small to store the string to be
+- returned.

+-I/O Queues
+-==========
+-
+- Many of the remaining functions in this section refer to the input
+-and output queues of a terminal device. These queues implement a form
+-of buffering _within the kernel_ independent of the buffering
+-implemented by I/O streams (*note I/O on Streams::).
+-
+- The "terminal input queue" is also sometimes referred to as its
+-"typeahead buffer". It holds the characters that have been received
+-from the terminal but not yet read by any process.
+-
+- The size of the input queue is described by the `MAX_INPUT' and
+-`_POSIX_MAX_INPUT' parameters; see *Note Limits for Files::. You are
+-guaranteed a queue size of at least `MAX_INPUT', but the queue might be
+-larger, and might even dynamically change size. If input flow control
+-is enabled by setting the `IXOFF' input mode bit (*note Input Modes::),
+-the terminal driver transmits STOP and START characters to the terminal
+-when necessary to prevent the queue from overflowing. Otherwise, input
+-may be lost if it comes in too fast from the terminal. In canonical
+-mode, all input stays in the queue until a newline character is
+-received, so the terminal input queue can fill up when you type a very
+-long line. *Note Canonical or Not::.
+-
+- The "terminal output queue" is like the input queue, but for output;
+-it contains characters that have been written by processes, but not yet
+-transmitted to the terminal. If output flow control is enabled by
+-setting the `IXON' input mode bit (*note Input Modes::), the terminal
+-driver obeys START and STOP characters sent by the terminal to stop and
+-restart transmission of output.
+-
+- "Clearing" the terminal input queue means discarding any characters
+-that have been received but not yet read. Similarly, clearing the
+-terminal output queue means discarding any characters that have been
+-written but not yet transmitted.

+-
+-Two Styles of Input: Canonical or Not
+-=====================================
+-
+- POSIX systems support two basic modes of input: canonical and
+-noncanonical.
+-
+- In "canonical input processing" mode, terminal input is processed in
+-lines terminated by newline (`'\n''), EOF, or EOL characters. No input
+-can be read until an entire line has been typed by the user, and the
+-`read' function (*note I/O Primitives::) returns at most a single line
+-of input, no matter how many bytes are requested.
+-
+- In canonical input mode, the operating system provides input editing
+-facilities: some characters are interpreted specially to perform editing
+-operations within the current line of text, such as ERASE and KILL.
+-*Note Editing Characters::.
+-
+- The constants `_POSIX_MAX_CANON' and `MAX_CANON' parameterize the
+-maximum number of bytes which may appear in a single line of canonical
+-input. *Note Limits for Files::. You are guaranteed a maximum line
+-length of at least `MAX_CANON' bytes, but the maximum might be larger,
+-and might even dynamically change size.
+-
+- In "noncanonical input processing" mode, characters are not grouped
+-into lines, and ERASE and KILL processing is not performed. The
+-granularity with which bytes are read in noncanonical input mode is
+-controlled by the MIN and TIME settings. *Note Noncanonical Input::.
+-
+- Most programs use canonical input mode, because this gives the user a
+-way to edit input line by line. The usual reason to use noncanonical
+-mode is when the program accepts single-character commands or provides
+-its own editing facilities.
+-
+- The choice of canonical or noncanonical input is controlled by the
+-`ICANON' flag in the `c_lflag' member of `struct termios'. *Note Local
+-Modes::.

+-Terminal Mode Data Types
+-------------------------
+-
+- The entire collection of attributes of a terminal is stored in a
+-structure of type `struct termios'. This structure is used with the
+-functions `tcgetattr' and `tcsetattr' to read and set the attributes.
+-
+- - Data Type: struct termios
+- Structure that records all the I/O attributes of a terminal. The
+- structure includes at least the following members:
+-
+- `tcflag_t c_iflag'
+- A bit mask specifying flags for input modes; see *Note Input
+- Modes::.
+-
+- `tcflag_t c_oflag'
+- A bit mask specifying flags for output modes; see *Note
+- Output Modes::.
+-
+- `tcflag_t c_cflag'
+- A bit mask specifying flags for control modes; see *Note
+- Control Modes::.
+-
+- `tcflag_t c_lflag'
+- A bit mask specifying flags for local modes; see *Note Local
+- Modes::.
+-
+- `cc_t c_cc[NCCS]'
+- An array specifying which characters are associated with
+- various control functions; see *Note Special Characters::.
+-
+- The `struct termios' structure also contains members which encode
+- input and output transmission speeds, but the representation is
+- not specified. *Note Line Speed::, for how to examine and store
+- the speed values.
+-
+- The following sections describe the details of the members of the
+-`struct termios' structure.
+-
+- - Data Type: tcflag_t
+- This is an unsigned integer type used to represent the various bit
+- masks for terminal flags.
+-
+- - Data Type: cc_t
+- This is an unsigned integer type used to represent characters
+- associated with various terminal control functions.
+-
+- - Macro: int NCCS
+- The value of this macro is the number of elements in the `c_cc'
+- array.

+-
+-Terminal Mode Functions
+------------------------
+-
+- - Function: int tcgetattr (int FILEDES, struct termios *TERMIOS-P)
+- This function is used to examine the attributes of the terminal
+- device with file descriptor FILEDES. The attributes are returned
+- in the structure that TERMIOS-P points to.
+-
+- If successful, `tcgetattr' returns 0. A return value of -1
+- indicates an error. The following `errno' error conditions are
+- defined for this function:
+-
+- `EBADF'
+- The FILEDES argument is not a valid file descriptor.
+-
+- `ENOTTY'
+- The FILEDES is not associated with a terminal.
+-
+- - Function: int tcsetattr (int FILEDES, int WHEN, const struct termios
+- *TERMIOS-P)
+- This function sets the attributes of the terminal device with file
+- descriptor FILEDES. The new attributes are taken from the
+- structure that TERMIOS-P points to.
+-
+- The WHEN argument specifies how to deal with input and output
+- already queued. It can be one of the following values:
+-
+- `TCSANOW'
+- Make the change immediately.
+-
+- `TCSADRAIN'
+- Make the change after waiting until all queued output has
+- been written. You should usually use this option when
+- changing parameters that affect output.
+-
+- `TCSAFLUSH'
+- This is like `TCSADRAIN', but also discards any queued input.
+-
+- `TCSASOFT'
+- This is a flag bit that you can add to any of the above
+- alternatives. Its meaning is to inhibit alteration of the
+- state of the terminal hardware. It is a BSD extension; it is
+- only supported on BSD systems and the GNU system.
+-
+- Using `TCSASOFT' is exactly the same as setting the `CIGNORE'
+- bit in the `c_cflag' member of the structure TERMIOS-P points
+- to. *Note Control Modes::, for a description of `CIGNORE'.
+-
+- If this function is called from a background process on its
+- controlling terminal, normally all processes in the process group
+- are sent a `SIGTTOU' signal, in the same way as if the process
+- were trying to write to the terminal. The exception is if the
+- calling process itself is ignoring or blocking `SIGTTOU' signals,
+- in which case the operation is performed and no signal is sent.
+- *Note Job Control::.
+-
+- If successful, `tcsetattr' returns 0. A return value of -1
+- indicates an error. The following `errno' error conditions are
+- defined for this function:
+-
+- `EBADF'
+- The FILEDES argument is not a valid file descriptor.
+-
+- `ENOTTY'
+- The FILEDES is not associated with a terminal.
+-
+- `EINVAL'
+- Either the value of the `when' argument is not valid, or
+- there is something wrong with the data in the TERMIOS-P
+- argument.
+-
+- Although `tcgetattr' and `tcsetattr' specify the terminal device
+-with a file descriptor, the attributes are those of the terminal device
+-itself and not of the file descriptor. This means that the effects of
+-changing terminal attributes are persistent; if another process opens
+-the terminal file later on, it will see the changed attributes even
+-though it doesn't have anything to do with the open file descriptor you
+-originally specified in changing the attributes.
+-
+- Similarly, if a single process has multiple or duplicated file
+-descriptors for the same terminal device, changing the terminal
+-attributes affects input and output to all of these file descriptors.
+-This means, for example, that you can't open one file descriptor or
+-stream to read from a terminal in the normal line-buffered, echoed
+-mode; and simultaneously have another file descriptor for the same
+-terminal that you use to read from it in single-character, non-echoed
+-mode. Instead, you have to explicitly switch the terminal back and
+-forth between the two modes.

+-
+-Setting Terminal Modes Properly
+--------------------------------
+-
+- When you set terminal modes, you should call `tcgetattr' first to
+-get the current modes of the particular terminal device, modify only
+-those modes that you are really interested in, and store the result with
+-`tcsetattr'.
+-
+- It's a bad idea to simply initialize a `struct termios' structure to
+-a chosen set of attributes and pass it directly to `tcsetattr'. Your
+-program may be run years from now, on systems that support members not
+-documented in this manual. The way to avoid setting these members to
+-unreasonable values is to avoid changing them.
+-
+- What's more, different terminal devices may require different mode
+-settings in order to function properly. So you should avoid blindly
+-copying attributes from one terminal device to another.
+-
+- When a member contains a collection of independent flags, as the
+-`c_iflag', `c_oflag' and `c_cflag' members do, even setting the entire
+-member is a bad idea, because particular operating systems have their
+-own flags. Instead, you should start with the current value of the
+-member and alter only the flags whose values matter in your program,
+-leaving any other flags unchanged.
+-
+- Here is an example of how to set one flag (`ISTRIP') in the `struct
+-termios' structure while properly preserving all the other data in the
+-structure:
+-
+- int
+- set_istrip (int desc, int value)
+- {
+- struct termios settings;
+- int result;
+-
+- result = tcgetattr (desc, &settings);
+- if (result < 0)
+- {
+- perror ("error in tcgetattr");
+- return 0;
+- }
+- settings.c_iflag &= ~ISTRIP;
+- if (value)
+- settings.c_iflag |= ISTRIP;
+- result = tcsetattr (desc, TCSANOW, &settings);
+- if (result < 0)
+- {
+- perror ("error in tcsetattr");
+- return 0;
+- }
+- return 1;
+- }

+-
+-Input Modes
+------------
+-
+- This section describes the terminal attribute flags that control
+-fairly low-level aspects of input processing: handling of parity errors,
+-break signals, flow control, and <RET> and <LFD> characters.
+-
+- All of these flags are bits in the `c_iflag' member of the `struct
+-termios' structure. The member is an integer, and you change flags
+-using the operators `&', `|' and `^'. Don't try to specify the entire
+-value for `c_iflag'--instead, change only specific flags and leave the
+-rest untouched (*note Setting Modes::).
+-
+- - Macro: tcflag_t INPCK
+- If this bit is set, input parity checking is enabled. If it is
+- not set, no checking at all is done for parity errors on input; the
+- characters are simply passed through to the application.
+-
+- Parity checking on input processing is independent of whether
+- parity detection and generation on the underlying terminal
+- hardware is enabled; see *Note Control Modes::. For example, you
+- could clear the `INPCK' input mode flag and set the `PARENB'
+- control mode flag to ignore parity errors on input, but still
+- generate parity on output.
+-
+- If this bit is set, what happens when a parity error is detected
+- depends on whether the `IGNPAR' or `PARMRK' bits are set. If
+- neither of these bits are set, a byte with a parity error is
+- passed to the application as a `'\0'' character.
+-
+- - Macro: tcflag_t IGNPAR
+- If this bit is set, any byte with a framing or parity error is
+- ignored. This is only useful if `INPCK' is also set.
+-
+- - Macro: tcflag_t PARMRK
+- If this bit is set, input bytes with parity or framing errors are
+- marked when passed to the program. This bit is meaningful only
+- when `INPCK' is set and `IGNPAR' is not set.
+-
+- The way erroneous bytes are marked is with two preceding bytes,
+- `377' and `0'. Thus, the program actually reads three bytes for
+- one erroneous byte received from the terminal.
+-
+- If a valid byte has the value `0377', and `ISTRIP' (see below) is
+- not set, the program might confuse it with the prefix that marks a
+- parity error. So a valid byte `0377' is passed to the program as
+- two bytes, `0377' `0377', in this case.
+-
+- - Macro: tcflag_t ISTRIP
+- If this bit is set, valid input bytes are stripped to seven bits;
+- otherwise, all eight bits are available for programs to read.
+-
+- - Macro: tcflag_t IGNBRK
+- If this bit is set, break conditions are ignored.
+-
+- A "break condition" is defined in the context of asynchronous
+- serial data transmission as a series of zero-value bits longer
+- than a single byte.
+-
+- - Macro: tcflag_t BRKINT
+- If this bit is set and `IGNBRK' is not set, a break condition
+- clears the terminal input and output queues and raises a `SIGINT'
+- signal for the foreground process group associated with the
+- terminal.
+-
+- If neither `BRKINT' nor `IGNBRK' are set, a break condition is
+- passed to the application as a single `'\0'' character if `PARMRK'
+- is not set, or otherwise as a three-character sequence `'\377'',
+- `'\0'', `'\0''.
+-
+- - Macro: tcflag_t IGNCR
+- If this bit is set, carriage return characters (`'\r'') are
+- discarded on input. Discarding carriage return may be useful on
+- terminals that send both carriage return and linefeed when you
+- type the <RET> key.
+-
+- - Macro: tcflag_t ICRNL
+- If this bit is set and `IGNCR' is not set, carriage return
+- characters (`'\r'') received as input are passed to the
+- application as newline characters (`'\n'').
+-
+- - Macro: tcflag_t INLCR
+- If this bit is set, newline characters (`'\n'') received as input
+- are passed to the application as carriage return characters
+- (`'\r'').
+-
+- - Macro: tcflag_t IXOFF
+- If this bit is set, start/stop control on input is enabled. In
+- other words, the computer sends STOP and START characters as
+- necessary to prevent input from coming in faster than programs are
+- reading it. The idea is that the actual terminal hardware that is
+- generating the input data responds to a STOP character by
+- suspending transmission, and to a START character by resuming
+- transmission. *Note Start/Stop Characters::.
+-
+- - Macro: tcflag_t IXON
+- If this bit is set, start/stop control on output is enabled. In
+- other words, if the computer receives a STOP character, it
+- suspends output until a START character is received. In this
+- case, the STOP and START characters are never passed to the
+- application program. If this bit is not set, then START and STOP
+- can be read as ordinary characters. *Note Start/Stop Characters::.
+-
+- - Macro: tcflag_t IXANY
+- If this bit is set, any input character restarts output when
+- output has been suspended with the STOP character. Otherwise,
+- only the START character restarts output.
+-
+- This is a BSD extension; it exists only on BSD systems and the GNU
+- system.
+-
+- - Macro: tcflag_t IMAXBEL
+- If this bit is set, then filling up the terminal input buffer
+- sends a BEL character (code `007') to the terminal to ring the
+- bell.
+-
+- This is a BSD extension.

+-Output Modes
+-------------
+-
+- This section describes the terminal flags and fields that control how
+-output characters are translated and padded for display. All of these
+-are contained in the `c_oflag' member of the `struct termios' structure.
+-
+- The `c_oflag' member itself is an integer, and you change the flags
+-and fields using the operators `&', `|', and `^'. Don't try to specify
+-the entire value for `c_oflag'--instead, change only specific flags and
+-leave the rest untouched (*note Setting Modes::).
+-
+- - Macro: tcflag_t OPOST
+- If this bit is set, output data is processed in some unspecified
+- way so that it is displayed appropriately on the terminal device.
+- This typically includes mapping newline characters (`'\n'') onto
+- carriage return and linefeed pairs.
+-
+- If this bit isn't set, the characters are transmitted as-is.
+-
+- The following three bits are BSD features, and they exist only BSD
+-systems and the GNU system. They are effective only if `OPOST' is set.
+-
+- - Macro: tcflag_t ONLCR
+- If this bit is set, convert the newline character on output into a
+- pair of characters, carriage return followed by linefeed.
+-
+- - Macro: tcflag_t OXTABS
+- If this bit is set, convert tab characters on output into the
+- appropriate number of spaces to emulate a tab stop every eight
+- columns.
+-
+- - Macro: tcflag_t ONOEOT
+- If this bit is set, discard `C-d' characters (code `004') on
+- output. These characters cause many dial-up terminals to

+-Control Modes
+--------------
+-
+- This section describes the terminal flags and fields that control
+-parameters usually associated with asynchronous serial data
+-transmission. These flags may not make sense for other kinds of
+-terminal ports (such as a network connection pseudo-terminal). All of
+-these are contained in the `c_cflag' member of the `struct termios'
+-structure.
+-
+- The `c_cflag' member itself is an integer, and you change the flags
+-and fields using the operators `&', `|', and `^'. Don't try to specify
+-the entire value for `c_cflag'--instead, change only specific flags and
+-leave the rest untouched (*note Setting Modes::).
+-
+- - Macro: tcflag_t CLOCAL
+- If this bit is set, it indicates that the terminal is connected
+- "locally" and that the modem status lines (such as carrier detect)
+- should be ignored.
+-
+- On many systems if this bit is not set and you call `open' without
+- the `O_NONBLOCK' flag set, `open' blocks until a modem connection
+- is established.
+-
+- If this bit is not set and a modem disconnect is detected, a
+- `SIGHUP' signal is sent to the controlling process group for the
+- terminal (if it has one). Normally, this causes the process to
+- exit; see *Note Signal Handling::. Reading from the terminal
+- after a disconnect causes an end-of-file condition, and writing
+- causes an `EIO' error to be returned. The terminal device must be
+- closed and reopened to clear the condition.
+-
+- - Macro: tcflag_t HUPCL
+- If this bit is set, a modem disconnect is generated when all
+- processes that have the terminal device open have either closed
+- the file or exited.
+-
+- - Macro: tcflag_t CREAD
+- If this bit is set, input can be read from the terminal.
+- Otherwise, input is discarded when it arrives.
+-
+- - Macro: tcflag_t CSTOPB
+- If this bit is set, two stop bits are used. Otherwise, only one
+- stop bit is used.
+-
+- - Macro: tcflag_t PARENB
+- If this bit is set, generation and detection of a parity bit are
+- enabled. *Note Input Modes::, for information on how input parity
+- errors are handled.
+-
+- If this bit is not set, no parity bit is added to output
+- characters, and input characters are not checked for correct
+- parity.
+-
+- - Macro: tcflag_t PARODD
+- This bit is only useful if `PARENB' is set. If `PARODD' is set,
+- odd parity is used, otherwise even parity is used.
+-
+- The control mode flags also includes a field for the number of bits
+-per character. You can use the `CSIZE' macro as a mask to extract the
+-value, like this: `settings.c_cflag & CSIZE'.
+-
+- - Macro: tcflag_t CSIZE
+- This is a mask for the number of bits per character.
+-
+- - Macro: tcflag_t CS5
+- This specifies five bits per byte.
+-
+- - Macro: tcflag_t CS6
+- This specifies six bits per byte.
+-
+- - Macro: tcflag_t CS7
+- This specifies seven bits per byte.
+-
+- - Macro: tcflag_t CS8
+- This specifies eight bits per byte.
+-
+- The following four bits are BSD extensions; this exist only on BSD
+-systems and the GNU system.
+-
+- - Macro: tcflag_t CCTS_OFLOW
+- If this bit is set, enable flow control of output based on the CTS
+- wire (RS232 protocol).
+-
+- - Macro: tcflag_t CRTS_IFLOW
+- If this bit is set, enable flow control of input based on the RTS
+- wire (RS232 protocol).
+-
+- - Macro: tcflag_t MDMBUF
+- If this bit is set, enable carrier-based flow control of output.
+-
+- - Macro: tcflag_t CIGNORE
+- If this bit is set, it says to ignore the control modes and line
+- speed values entirely. This is only meaningful in a call to
+- `tcsetattr'.
+-
+- The `c_cflag' member and the line speed values returned by
+- `cfgetispeed' and `cfgetospeed' will be unaffected by the call.
+- `CIGNORE' is useful if you want to set all the software modes in

+-Local Modes
+------------
+-
+- This section describes the flags for the `c_lflag' member of the
+-`struct termios' structure. These flags generally control higher-level
+-aspects of input processing than the input modes flags described in
+-*Note Input Modes::, such as echoing, signals, and the choice of
+-canonical or noncanonical input.
+-
+- The `c_lflag' member itself is an integer, and you change the flags
+-and fields using the operators `&', `|', and `^'. Don't try to specify
+-the entire value for `c_lflag'--instead, change only specific flags and
+-leave the rest untouched (*note Setting Modes::).
+-
+- - Macro: tcflag_t ICANON
+- This bit, if set, enables canonical input processing mode.
+- Otherwise, input is processed in noncanonical mode. *Note
+- Canonical or Not::.
+-
+- - Macro: tcflag_t ECHO
+- If this bit is set, echoing of input characters back to the
+- terminal is enabled.
+-
+- - Macro: tcflag_t ECHOE
+- If this bit is set, echoing indicates erasure of input with the
+- ERASE character by erasing the last character in the current line
+- from the screen. Otherwise, the character erased is re-echoed to
+- show what has happened (suitable for a printing terminal).
+-
+- This bit only controls the display behavior; the `ICANON' bit by
+- itself controls actual recognition of the ERASE character and
+- erasure of input, without which `ECHOE' is simply irrelevant.
+-
+- - Macro: tcflag_t ECHOPRT
+- This bit is like `ECHOE', enables display of the ERASE character in
+- a way that is geared to a hardcopy terminal. When you type the
+- ERASE character, a `\' character is printed followed by the first
+- character erased. Typing the ERASE character again just prints
+- the next character erased. Then, the next time you type a normal
+- character, a `/' character is printed before the character echoes.
+-
+- This is a BSD extension, and exists only in BSD systems and the
+- GNU system.
+-
+- - Macro: tcflag_t ECHOK
+- This bit enables special display of the KILL character by moving
+- to a new line after echoing the KILL character normally. The
+- behavior of `ECHOKE' (below) is nicer to look at.
+-
+- If this bit is not set, the KILL character echoes just as it would
+- if it were not the KILL character. Then it is up to the user to
+- remember that the KILL character has erased the preceding input;
+- there is no indication of this on the screen.
+-
+- This bit only controls the display behavior; the `ICANON' bit by
+- itself controls actual recognition of the KILL character and
+- erasure of input, without which `ECHOK' is simply irrelevant.
+-
+- - Macro: tcflag_t ECHOKE
+- This bit is similar to `ECHOK'. It enables special display of the
+- KILL character by erasing on the screen the entire line that has
+- been killed. This is a BSD extension, and exists only in BSD
+- systems and the GNU system.
+-
+- - Macro: tcflag_t ECHONL
+- If this bit is set and the `ICANON' bit is also set, then the
+- newline (`'\n'') character is echoed even if the `ECHO' bit is not
+- set.
+-
+- - Macro: tcflag_t ECHOCTL
+- If this bit is set and the `ECHO' bit is also set, echo control
+- characters with `^' followed by the corresponding text character.
+- Thus, control-A echoes as `^A'. This is usually the preferred mode
+- for interactive input, because echoing a control character back to
+- the terminal could have some undesired effect on the terminal.
+-
+- This is a BSD extension, and exists only in BSD systems and the
+- GNU system.
+-
+- - Macro: tcflag_t ISIG
+- This bit controls whether the INTR, QUIT, and SUSP characters are
+- recognized. The functions associated with these characters are
+- performed if and only if this bit is set. Being in canonical or
+- noncanonical input mode has no affect on the interpretation of
+- these characters.
+-
+- You should use caution when disabling recognition of these
+- characters. Programs that cannot be interrupted interactively are
+- very user-unfriendly. If you clear this bit, your program should
+- provide some alternate interface that allows the user to
+- interactively send the signals associated with these characters,
+- or to escape from the program.
+-
+- *Note Signal Characters::.
+-
+- - Macro: tcflag_t IEXTEN
+- POSIX.1 gives `IEXTEN' implementation-defined meaning, so you
+- cannot rely on this interpretation on all systems.
+-
+- On BSD systems and the GNU system, it enables the LNEXT and
+- DISCARD characters. *Note Other Special::.
+-
+- - Macro: tcflag_t NOFLSH
+- Normally, the INTR, QUIT, and SUSP characters cause input and
+- output queues for the terminal to be cleared. If this bit is set,
+- the queues are not cleared.
+-
+- - Macro: tcflag_t TOSTOP
+- If this bit is set and the system supports job control, then
+- `SIGTTOU' signals are generated by background processes that
+- attempt to write to the terminal. *Note Access to the Terminal::.
+-
+- The following bits are BSD extensions; they exist only in BSD systems
+-and the GNU system.
+-
+- - Macro: tcflag_t ALTWERASE
+- This bit determines how far the WERASE character should erase. The
+- WERASE character erases back to the beginning of a word; the
+- question is, where do words begin?
+-
+- If this bit is clear, then the beginning of a word is a
+- nonwhitespace character following a whitespace character. If the
+- bit is set, then the beginning of a word is an alphanumeric
+- character or underscore following a character which is none of
+- those.
+-
+- *Note Editing Characters::, for more information about the WERASE
+- character.
+-
+- - Macro: tcflag_t FLUSHO
+- This is the bit that toggles when the user types the DISCARD
+- character. While this bit is set, all output is discarded. *Note
+- Other Special::.
+-
+- - Macro: tcflag_t NOKERNINFO
+- Setting this bit disables handling of the STATUS character. *Note
+- Other Special::.
+-
+- - Macro: tcflag_t PENDIN
+- If this bit is set, it indicates that there is a line of input that
+- needs to be reprinted. Typing the REPRINT character sets this
+- bit; the bit remains set until reprinting is finished. *Note
+- Editing Characters::.

+-
+-Line Speed
+-----------
+-
+- The terminal line speed tells the computer how fast to read and write
+-data on the terminal.
+-
+- If the terminal is connected to a real serial line, the terminal
+-speed you specify actually controls the line--if it doesn't match the
+-terminal's own idea of the speed, communication does not work. Real
+-serial ports accept only certain standard speeds. Also, particular
+-hardware may not support even all the standard speeds. Specifying a
+-speed of zero hangs up a dialup connection and turns off modem control
+-signals.
+-
+- If the terminal is not a real serial line (for example, if it is a
+-network connection), then the line speed won't really affect data
+-transmission speed, but some programs will use it to determine the
+-amount of padding needed. It's best to specify a line speed value that
+-matches the actual speed of the actual terminal, but you can safely
+-experiment with different values to vary the amount of padding.
+-
+- There are actually two line speeds for each terminal, one for input
+-and one for output. You can set them independently, but most often
+-terminals use the same speed for both directions.
+-
+- The speed values are stored in the `struct termios' structure, but
+-don't try to access them in the `struct termios' structure directly.
+-Instead, you should use the following functions to read and store them:
+-
+- - Function: speed_t cfgetospeed (const struct termios *TERMIOS-P)
+- This function returns the output line speed stored in the structure
+- `*TERMIOS-P'.
+-
+- - Function: speed_t cfgetispeed (const struct termios *TERMIOS-P)
+- This function returns the input line speed stored in the structure
+- `*TERMIOS-P'.
+-
+- - Function: int cfsetospeed (struct termios *TERMIOS-P, speed_t SPEED)
+- This function stores SPEED in `*TERMIOS-P' as the output speed.
+- The normal return value is 0; a value of -1 indicates an error.
+- If SPEED is not a speed, `cfsetospeed' returns -1.
+-
+- - Function: int cfsetispeed (struct termios *TERMIOS-P, speed_t SPEED)
+- This function stores SPEED in `*TERMIOS-P' as the input speed.
+- The normal return value is 0; a value of -1 indicates an error.
+- If SPEED is not a speed, `cfsetospeed' returns -1.
+-
+- - Function: int cfsetspeed (struct termios *TERMIOS-P, speed_t SPEED)
+- This function stores SPEED in `*TERMIOS-P' as both the input and
+- output speeds. The normal return value is 0; a value of -1
+- indicates an error. If SPEED is not a speed, `cfsetspeed' returns
+- -1. This function is an extension in 4.4 BSD.
+-
+- - Data Type: speed_t
+- The `speed_t' type is an unsigned integer data type used to
+- represent line speeds.
+-
+- The functions `cfsetospeed' and `cfsetispeed' report errors only for
+-speed values that the system simply cannot handle. If you specify a
+-speed value that is basically acceptable, then those functions will
+-succeed. But they do not check that a particular hardware device can
+-actually support the specified speeds--in fact, they don't know which
+-device you plan to set the speed for. If you use `tcsetattr' to set
+-the speed of a particular device to a value that it cannot handle,
+-`tcsetattr' returns -1.
+-
+- *Portability note:* In the GNU library, the functions above accept
+-speeds measured in bits per second as input, and return speed values
+-measured in bits per second. Other libraries require speeds to be
+-indicated by special codes. For POSIX.1 portability, you must use one
+-of the following symbols to represent the speed; their precise numeric
+-values are system-dependent, but each name has a fixed meaning: `B110'
+-stands for 110 bps, `B300' for 300 bps, and so on. There is no
+-portable way to represent any speed but these, but these are the only
+-speeds that typical serial lines can support.
+-
+- B0 B50 B75 B110 B134 B150 B200
+- B300 B600 B1200 B1800 B2400 B4800
+- B9600 B19200 B38400 B57600 B115200
+- B230400 B460800
+-
+- BSD defines two additional speed symbols as aliases: `EXTA' is an
+-alias for `B19200' and `EXTB' is an alias for `B38400'. These aliases
+-are obsolete.

+-File: libc.info, Node: Special Characters, Next: Noncanonical Input, Prev: Line Speed, Up: Terminal Modes
+-
+-Special Characters
+-------------------
+-
+- In canonical input, the terminal driver recognizes a number of
+-special characters which perform various control functions. These
+-include the ERASE character (usually <DEL>) for editing input, and
+-other editing characters. The INTR character (normally `C-c') for
+-sending a `SIGINT' signal, and other signal-raising characters, may be
+-available in either canonical or noncanonical input mode. All these
+-characters are described in this section.
+-
+- The particular characters used are specified in the `c_cc' member of
+-the `struct termios' structure. This member is an array; each element
+-specifies the character for a particular role. Each element has a
+-symbolic constant that stands for the index of that element--for
+-example, `VINTR' is the index of the element that specifies the INTR
+-character, so storing `'='' in `TERMIOS.c_cc[VINTR]' specifies `=' as
+-the INTR character.
+-
+- On some systems, you can disable a particular special character
+-function by specifying the value `_POSIX_VDISABLE' for that role. This
+-value is unequal to any possible character code. *Note Options for
+-Files::, for more information about how to tell whether the operating
+-system you are using supports `_POSIX_VDISABLE'.

+-
+-Error Codes
+-===========
+-
+- The error code macros are defined in the header file `errno.h'. All
+-of them expand into integer constant values. Some of these error codes
+-can't occur on the GNU system, but they can occur using the GNU library
+-on other systems.
+-
+- - Macro: int EPERM
+- Operation not permitted; only the owner of the file (or other
+- resource) or processes with special privileges can perform the
+- operation.
+-
+- - Macro: int ENOENT
+- No such file or directory. This is a "file doesn't exist" error
+- for ordinary files that are referenced in contexts where they are
+- expected to already exist.
+-
+- - Macro: int ESRCH
+- No process matches the specified process ID.
+-
+- - Macro: int EINTR
+- Interrupted function call; an asynchronous signal occurred and
+- prevented completion of the call. When this happens, you should
+- try the call again.
+-
+- You can choose to have functions resume after a signal that is
+- handled, rather than failing with `EINTR'; see *Note Interrupted
+- Primitives::.
+-
+- - Macro: int EIO
+- Input/output error; usually used for physical read or write errors.
+-
+- - Macro: int ENXIO
+- No such device or address. The system tried to use the device
+- represented by a file you specified, and it couldn't find the
+- device. This can mean that the device file was installed
+- incorrectly, or that the physical device is missing or not
+- correctly attached to the computer.
+-
+- - Macro: int E2BIG
+- Argument list too long; used when the arguments passed to a new
+- program being executed with one of the `exec' functions (*note
+- Executing a File::) occupy too much memory space. This condition
+- never arises in the GNU system.
+-
+- - Macro: int ENOEXEC
+- Invalid executable file format. This condition is detected by the
+- `exec' functions; see *Note Executing a File::.
+-
+- - Macro: int EBADF
+- Bad file descriptor; for example, I/O on a descriptor that has been
+- closed or reading from a descriptor open only for writing (or vice
+- versa).
+-
+- - Macro: int ECHILD
+- There are no child processes. This error happens on operations
+- that are supposed to manipulate child processes, when there aren't
+- any processes to manipulate.
+-
+- - Macro: int EDEADLK
+- Deadlock avoided; allocating a system resource would have resulted
+- in a deadlock situation. The system does not guarantee that it
+- will notice all such situations. This error means you got lucky
+- and the system noticed; it might just hang. *Note File Locks::,
+- for an example.
+-
+- - Macro: int ENOMEM
+- No memory available. The system cannot allocate more virtual
+- memory because its capacity is full.
+-
+- - Macro: int EACCES
+- Permission denied; the file permissions do not allow the attempted
+- operation.
+-
+- - Macro: int EFAULT
+- Bad address; an invalid pointer was detected. In the GNU system,
+- this error never happens; you get a signal instead.
+-
+- - Macro: int ENOTBLK
+- A file that isn't a block special file was given in a situation
+- that requires one. For example, trying to mount an ordinary file
+- as a file system in Unix gives this error.
+-
+- - Macro: int EBUSY
+- Resource busy; a system resource that can't be shared is already
+- in use. For example, if you try to delete a file that is the root
+- of a currently mounted filesystem, you get this error.
+-
+- - Macro: int EEXIST
+- File exists; an existing file was specified in a context where it
+- only makes sense to specify a new file.
+-
+- - Macro: int EXDEV
+- An attempt to make an improper link across file systems was
+- detected. This happens not only when you use `link' (*note Hard
+- Links::) but also when you rename a file with `rename' (*note
+- Renaming Files::).
+-
+- - Macro: int ENODEV
+- The wrong type of device was given to a function that expects a
+- particular sort of device.
+-
+- - Macro: int ENOTDIR
+- A file that isn't a directory was specified when a directory is
+- required.
+-
+- - Macro: int EISDIR
+- File is a directory; you cannot open a directory for writing, or
+- create or remove hard links to it.
+-
+- - Macro: int EINVAL
+- Invalid argument. This is used to indicate various kinds of
+- problems with passing the wrong argument to a library function.
+-
+- - Macro: int EMFILE
+- The current process has too many files open and can't open any
+- more. Duplicate descriptors do count toward this limit.
+-
+- In BSD and GNU, the number of open files is controlled by a
+- resource limit that can usually be increased. If you get this
+- error, you might want to increase the `RLIMIT_NOFILE' limit or
+- make it unlimited; *note Limits on Resources::.
+-
+- - Macro: int ENFILE
+- There are too many distinct file openings in the entire system.
+- Note that any number of linked channels count as just one file
+- opening; see *Note Linked Channels::. This error never occurs in
+- the GNU system.
+-
+- - Macro: int ENOTTY
+- Inappropriate I/O control operation, such as trying to set terminal
+- modes on an ordinary file.
+-
+- - Macro: int ETXTBSY
+- An attempt to execute a file that is currently open for writing, or
+- write to a file that is currently being executed. Often using a
+- debugger to run a program is considered having it open for writing
+- and will cause this error. (The name stands for "text file
+- busy".) This is not an error in the GNU system; the text is
+- copied as necessary.
+-
+- - Macro: int EFBIG
+- File too big; the size of a file would be larger than allowed by
+- the system.
+-
+- - Macro: int ENOSPC
+- No space left on device; write operation on a file failed because
+- the disk is full.
+-
+- - Macro: int ESPIPE
+- Invalid seek operation (such as on a pipe).
+-
+- - Macro: int EROFS
+- An attempt was made to modify something on a read-only file system.
+-
+- - Macro: int EMLINK
+- Too many links; the link count of a single file would become too
+- large. `rename' can cause this error if the file being renamed
+- already has as many links as it can take (*note Renaming Files::).
+-
+- - Macro: int EPIPE
+- Broken pipe; there is no process reading from the other end of a
+- pipe. Every library function that returns this error code also
+- generates a `SIGPIPE' signal; this signal terminates the program
+- if not handled or blocked. Thus, your program will never actually
+- see `EPIPE' unless it has handled or blocked `SIGPIPE'.
+-
+- - Macro: int EDOM
+- Domain error; used by mathematical functions when an argument
+- value does not fall into the domain over which the function is
+- defined.
+-
+- - Macro: int ERANGE
+- Range error; used by mathematical functions when the result value
+- is not representable because of overflow or underflow.
+-
+- - Macro: int EAGAIN
+- Resource temporarily unavailable; the call might work if you try
+- again later. The macro `EWOULDBLOCK' is another name for `EAGAIN';
+- they are always the same in the GNU C library.
+-
+- This error can happen in a few different situations:
+-
+- * An operation that would block was attempted on an object that
+- has non-blocking mode selected. Trying the same operation
+- again will block until some external condition makes it
+- possible to read, write, or connect (whatever the operation).
+- You can use `select' to find out when the operation will be
+- possible; *note Waiting for I/O::.
+-
+- *Portability Note:* In many older Unix systems, this condition
+- was indicated by `EWOULDBLOCK', which was a distinct error
+- code different from `EAGAIN'. To make your program portable,
+- you should check for both codes and treat them the same.
+-
+- * A temporary resource shortage made an operation impossible.
+- `fork' can return this error. It indicates that the shortage
+- is expected to pass, so your program can try the call again
+- later and it may succeed. It is probably a good idea to
+- delay for a few seconds before trying it again, to allow time
+- for other processes to release scarce resources. Such
+- shortages are usually fairly serious and affect the whole
+- system, so usually an interactive program should report the
+- error to the user and return to its command loop.
+-
+- - Macro: int EWOULDBLOCK
+- In the GNU C library, this is another name for `EAGAIN' (above).
+- The values are always the same, on every operating system.
+-
+- C libraries in many older Unix systems have `EWOULDBLOCK' as a
+- separate error code.
+-
+- - Macro: int EINPROGRESS
+- An operation that cannot complete immediately was initiated on an
+- object that has non-blocking mode selected. Some functions that
+- must always block (such as `connect'; *note Connecting::) never
+- return `EAGAIN'. Instead, they return `EINPROGRESS' to indicate
+- that the operation has begun and will take some time. Attempts to
+- manipulate the object before the call completes return `EALREADY'.
+- You can use the `select' function to find out when the pending
+- operation has completed; *note Waiting for I/O::.
+-
+- - Macro: int EALREADY
+- An operation is already in progress on an object that has
+- non-blocking mode selected.
+-
+- - Macro: int ENOTSOCK
+- A file that isn't a socket was specified when a socket is required.
+-
+- - Macro: int EMSGSIZE
+- The size of a message sent on a socket was larger than the
+- supported maximum size.
+-
+- - Macro: int EPROTOTYPE
+- The socket type does not support the requested communications
+- protocol.
+-
+- - Macro: int ENOPROTOOPT
+- You specified a socket option that doesn't make sense for the
+- particular protocol being used by the socket. *Note Socket
+- Options::.
+-
+- - Macro: int EPROTONOSUPPORT
+- The socket domain does not support the requested communications
+- protocol (perhaps because the requested protocol is completely
+- invalid). *Note Creating a Socket::.
+-
+- - Macro: int ESOCKTNOSUPPORT
+- The socket type is not supported.
+-
+- - Macro: int EOPNOTSUPP
+- The operation you requested is not supported. Some socket
+- functions don't make sense for all types of sockets, and others
+- may not be implemented for all communications protocols. In the
+- GNU system, this error can happen for many calls when the object
+- does not support the particular operation; it is a generic
+- indication that the server knows nothing to do for that call.
+-
+- - Macro: int EPFNOSUPPORT
+- The socket communications protocol family you requested is not
+- supported.
+-
+- - Macro: int EAFNOSUPPORT
+- The address family specified for a socket is not supported; it is
+- inconsistent with the protocol being used on the socket. *Note
+- Sockets::.
+-
+- - Macro: int EADDRINUSE
+- The requested socket address is already in use. *Note Socket
+- Addresses::.
+-
+- - Macro: int EADDRNOTAVAIL
+- The requested socket address is not available; for example, you
+- tried to give a socket a name that doesn't match the local host
+- name. *Note Socket Addresses::.
+-
+- - Macro: int ENETDOWN
+- A socket operation failed because the network was down.
+-
+- - Macro: int ENETUNREACH
+- A socket operation failed because the subnet containing the remote
+- host was unreachable.
+-
+- - Macro: int ENETRESET
+- A network connection was reset because the remote host crashed.
+-
+- - Macro: int ECONNABORTED
+- A network connection was aborted locally.
+-
+- - Macro: int ECONNRESET
+- A network connection was closed for reasons outside the control of
+- the local host, such as by the remote machine rebooting or an
+- unrecoverable protocol violation.
+-
+- - Macro: int ENOBUFS
+- The kernel's buffers for I/O operations are all in use. In GNU,
+- this error is always synonymous with `ENOMEM'; you may get one or
+- the other from network operations.
+-
+- - Macro: int EISCONN
+- You tried to connect a socket that is already connected. *Note
+- Connecting::.
+-
+- - Macro: int ENOTCONN
+- The socket is not connected to anything. You get this error when
+- you try to transmit data over a socket, without first specifying a
+- destination for the data. For a connectionless socket (for
+- datagram protocols, such as UDP), you get `EDESTADDRREQ' instead.
+-
+- - Macro: int EDESTADDRREQ
+- No default destination address was set for the socket. You get
+- this error when you try to transmit data over a connectionless
+- socket, without first specifying a destination for the data with
+- `connect'.
+-
+- - Macro: int ESHUTDOWN
+- The socket has already been shut down.
+-
+- - Macro: int ETOOMANYREFS
+- ???
+-
+- - Macro: int ETIMEDOUT
+- A socket operation with a specified timeout received no response
+- during the timeout period.
+-
+- - Macro: int ECONNREFUSED
+- A remote host refused to allow the network connection (typically
+- because it is not running the requested service).
+-
+- - Macro: int ELOOP
+- Too many levels of symbolic links were encountered in looking up a
+- file name. This often indicates a cycle of symbolic links.
+-
+- - Macro: int ENAMETOOLONG
+- Filename too long (longer than `PATH_MAX'; *note Limits for
+- Files::) or host name too long (in `gethostname' or `sethostname';
+- *note Host Identification::).
+-
+- - Macro: int EHOSTDOWN
+- The remote host for a requested network connection is down.
+-
+- - Macro: int EHOSTUNREACH
+- The remote host for a requested network connection is not
+- reachable.
+-
+- - Macro: int ENOTEMPTY
+- Directory not empty, where an empty directory was expected.
+- Typically, this error occurs when you are trying to delete a
+- directory.
+-
+- - Macro: int EPROCLIM
+- This means that the per-user limit on new process would be
+- exceeded by an attempted `fork'. *Note Limits on Resources::, for
+- details on the `RLIMIT_NPROC' limit.
+-
+- - Macro: int EUSERS
+- The file quota system is confused because there are too many users.
+-
+- - Macro: int EDQUOT
+- The user's disk quota was exceeded.
+-
+- - Macro: int ESTALE
+- Stale NFS file handle. This indicates an internal confusion in
+- the NFS system which is due to file system rearrangements on the
+- server host. Repairing this condition usually requires unmounting
+- and remounting the NFS file system on the local host.

+-Error Messages
+-==============
+-
+- The library has functions and variables designed to make it easy for
+-your program to report informative error messages in the customary
+-format about the failure of a library call. The functions `strerror'
+-and `perror' give you the standard error message for a given error
+-code; the variable `program_invocation_short_name' gives you convenient
+-access to the name of the program that encountered the error.
+-
+- - Function: char * strerror (int ERRNUM)
+- The `strerror' function maps the error code (*note Checking for
+- Errors::) specified by the ERRNUM argument to a descriptive error
+- message string. The return value is a pointer to this string.
+-
+- The value ERRNUM normally comes from the variable `errno'.
+-
+- You should not modify the string returned by `strerror'. Also, if
+- you make subsequent calls to `strerror', the string might be
+- overwritten. (But it's guaranteed that no library function ever
+- calls `strerror' behind your back.)
+-
+- The function `strerror' is declared in `string.h'.
+-
+- - Function: char * strerror_r (int ERRNUM, char *BUF, size_t N)
+- The `strerror_r' function works like `strerror' but instead of
+- returning the error message in a statically allocated buffer
+- shared by all threads in the process, it returns a private copy
+- for the thread. This might be either some permanent global data or
+- a message string in the user supplied buffer starting at BUF with
+- the length of N bytes.
+-
+- At most N characters are written (including the NUL byte) so it is
+- up to the user to select the buffer large enough.
+-
+- This function should always be used in multi-threaded programs
+- since there is no way to guarantee the string returned by
+- `strerror' really belongs to the last call of the current thread.
+-
+- This function `strerror_r' is a GNU extension and it is declared in
+- `string.h'.
+-
+- - Function: void perror (const char *MESSAGE)
+- This function prints an error message to the stream `stderr'; see
+- *Note Standard Streams::. The orientation of `stderr' is not
+- changed.
+-
+- If you call `perror' with a MESSAGE that is either a null pointer
+- or an empty string, `perror' just prints the error message
+- corresponding to `errno', adding a trailing newline.
+-
+- If you supply a non-null MESSAGE argument, then `perror' prefixes
+- its output with this string. It adds a colon and a space
+- character to separate the MESSAGE from the error string
+- corresponding to `errno'.
+-
+- The function `perror' is declared in `stdio.h'.
+-
+- `strerror' and `perror' produce the exact same message for any given
+-error code; the precise text varies from system to system. On the GNU
+-system, the messages are fairly short; there are no multi-line messages
+-or embedded newlines. Each error message begins with a capital letter
+-and does not include any terminating punctuation.
+-
+- *Compatibility Note:* The `strerror' function was introduced in
+-ISO C89. Many older C systems do not support this function yet.
+-
+- Many programs that don't read input from the terminal are designed to
+-exit if any system call fails. By convention, the error message from
+-such a program should start with the program's name, sans directories.
+-You can find that name in the variable `program_invocation_short_name';
+-the full file name is stored the variable `program_invocation_name'.
+-
+- - Variable: char * program_invocation_name
+- This variable's value is the name that was used to invoke the
+- program running in the current process. It is the same as
+- `argv[0]'. Note that this is not necessarily a useful file name;
+- often it contains no directory names. *Note Program Arguments::.
+-
+- - Variable: char * program_invocation_short_name
+- This variable's value is the name that was used to invoke the
+- program running in the current process, with directory names
+- removed. (That is to say, it is the same as
+- `program_invocation_name' minus everything up to the last slash,
+- if any.)
+-
+- The library initialization code sets up both of these variables
+-before calling `main'.
+-
+- *Portability Note:* These two variables are GNU extensions. If you
+-want your program to work with non-GNU libraries, you must save the
+-value of `argv[0]' in `main', and then strip off the directory names
+-yourself. We added these extensions to make it possible to write
+-self-contained error-reporting subroutines that require no explicit
+-cooperation from `main'.
+-
+- Here is an example showing how to handle failure to open a file
+-correctly. The function `open_sesame' tries to open the named file for
+-reading and returns a stream if successful. The `fopen' library
+-function returns a null pointer if it couldn't open the file for some
+-reason. In that situation, `open_sesame' constructs an appropriate
+-error message using the `strerror' function, and terminates the
+-program. If we were going to make some other library calls before
+-passing the error code to `strerror', we'd have to save it in a local
+-variable instead, because those other library functions might overwrite
+-`errno' in the meantime.
+-
+- #include <errno.h>
+- #include <stdio.h>
+- #include <stdlib.h>
+- #include <string.h>
+-
+- FILE *
+- open_sesame (char *name)
+- {
+- FILE *stream;
+-
+- errno = 0;
+- stream = fopen (name, "r");
+- if (stream == NULL)
+- {
+- fprintf (stderr, "%s: Couldn't open file %s; %s\n",
+- program_invocation_short_name, name, strerror (errno));
+- exit (EXIT_FAILURE);
+- }
+- else
+- return stream;
+- }
+-
+- Using `perror' has the advantage that the function is portable and
+-available on all systems implementing ISO C. But often the text
+-`perror' generates is not what is wanted and there is no way to extend
+-or change what `perror' does. The GNU coding standard, for instance,
+-requires error messages to be preceded by the program name and programs
+-which read some input files should should provide information about the
+-input file name and the line number in case an error is encountered
+-while reading the file. For these occasions there are two functions
+-available which are widely used throughout the GNU project. These
+-functions are declared in `error.h'.
+-
+- - Function: void error (int STATUS, int ERRNUM, const char *FORMAT,
+- ...)
+- The `error' function can be used to report general problems during
+- program execution. The FORMAT argument is a format string just
+- like those given to the `printf' family of functions. The
+- arguments required for the format can follow the FORMAT parameter.
+- Just like `perror', `error' also can report an error code in
+- textual form. But unlike `perror' the error value is explicitly
+- passed to the function in the ERRNUM parameter. This elimintates
+- the problem mentioned above that the error reporting function must
+- be called immediately after the function causing the error since
+- otherwise `errno' might have a different value.
+-
+- The `error' prints first the program name. If the application
+- defined a global variable `error_print_progname' and points it to a
+- function this function will be called to print the program name.
+- Otherwise the string from the global variable `program_name' is
+- used. The program name is followed by a colon and a space which
+- in turn is followed by the output produced by the format string.
+- If the ERRNUM parameter is non-zero the format string output is
+- followed by a colon and a space, followed by the error message for
+- the error code ERRNUM. In any case is the output terminated with
+- a newline.
+-
+- The output is directed to the `stderr' stream. If the `stderr'
+- wasn't oriented before the call it will be narrow-oriented
+- afterwards.
+-
+- The function will return unless the STATUS parameter has a
+- non-zero value. In this case the function will call `exit' with
+- the STATUS value for its parameter and therefore never return. If
+- `error' returns the global variable `error_message_count' is
+- incremented by one to keep track of the number of errors reported.
+-
+- - Function: void error_at_line (int STATUS, int ERRNUM, const char
+- *FNAME, unsigned int LINENO, const char *FORMAT, ...)
+- The `error_at_line' function is very similar to the `error'
+- function. The only difference are the additional parameters FNAME
+- and LINENO. The handling of the other parameters is identical to
+- that of `error' except that between the program name and the string
+- generated by the format string additional text is inserted.
+-
+- Directly following the program name a colon, followed by the file
+- name pointer to by FNAME, another colon, and a value of LINENO is
+- printed.
+-
+- This additional output of course is meant to be used to locate an
+- error in an input file (like a programming language source code
+- file etc).
+-
+- If the global variable `error_one_per_line' is set to a non-zero
+- value `error_at_line' will avoid printing consecutive messages for
+- the same file anem line. Repetition which are not directly
+- following each other are not caught.
+-
+- Just like `error' this function only returned if STATUS is zero.
+- Otherwise `exit' is called with the non-zero value. If `error'
+- returns the global variable `error_message_count' is incremented
+- by one to keep track of the number of errors reported.
+-
+- As mentioned above the `error' and `error_at_line' functions can be
+-customized by defining a variable named `error_print_progname'.
+-
+- - Variable: void (* error_print_progname ) (void)
+- If the `error_print_progname' variable is defined to a non-zero
+- value the function pointed to is called by `error' or
+- `error_at_line'. It is expected to print the program name or do
+- something similarly useful.
+-
+- The function is expected to be print to the `stderr' stream and
+- must be able to handle whatever orientation the stream has.
+-
+- The variable is global and shared by all threads.
+-
+- - Variable: unsigned int error_message_count
+- The `error_message_count' variable is incremented whenever one of
+- the functions `error' or `error_at_line' returns. The variable is
+- global and shared by all threads.
+-
+- - Variable: int error_one_per_line
+- The `error_one_per_line' variable influences only `error_at_line'.
+- Normally the `error_at_line' function creates output for every
+- invocation. If `error_one_per_line' is set to a non-zero value
+- `error_at_line' keeps track of the last file name and line number
+- for which an error was reported and avoid directly following
+- messages for the same file and line. This variable is global and
+- shared by all threads.
+-
+-A program which read some input file and reports errors in it could look
+-like this:
+-
+- {
+- char *line = NULL;
+- size_t len = 0;
+- unsigned int lineno = 0;
+-
+- error_message_count = 0;
+- while (! feof_unlocked (fp))
+- {
+- ssize_t n = getline (&line, &len, fp);
+- if (n <= 0)
+- /* End of file or error. */
+- break;
+- ++lineno;
+-
+- /* Process the line. */
+- ...
+-
+- if (Detect error in line)
+- error_at_line (0, errval, filename, lineno,
+- "some error text %s", some_variable);
+- }
+-
+- if (error_message_count != 0)
+- error (EXIT_FAILURE, 0, "%u errors found", error_message_count);
+- }
+-
+- `error' and `error_at_line' are clearly the functions of choice and
+-enable the programmer to write applications which follow the GNU coding
+-standard. The GNU libc additionally contains functions which are used
+-in BSD for the same purpose. These functions are declared in `err.h'.
+-It is generally advised to not use these functions. They are included
+-only for compatibility.
+-
+- - Function: void warn (const char *FORMAT, ...)
+- The `warn' function is roughly equivalent to a call like
+- error (0, errno, format, the parameters)
+-
+- except that the global variables `error' respects and modifies are
+- not used.
+-
+- - Function: void vwarn (const char *FORMAT, va_list)
+- The `vwarn' function is just like `warn' except that the
+- parameters for the handling of the format string FORMAT are passed
+- in as an value of type `va_list'.
+-
+- - Function: void warnx (const char *FORMAT, ...)
+- The `warnx' function is roughly equivalent to a call like
+- error (0, 0, format, the parameters)
+-
+- except that the global variables `error' respects and modifies are
+- not used. The difference to `warn' is that no error number string
+- is printed.
+-
+- - Function: void vwarnx (const char *FORMAT, va_list)
+- The `vwarnx' function is just like `warnx' except that the
+- parameters for the handling of the format string FORMAT are passed
+- in as an value of type `va_list'.
+-
+- - Function: void err (int STATUS, const char *FORMAT, ...)
+- The `err' function is roughly equivalent to a call like
+- error (status, errno, format, the parameters)
+-
+- except that the global variables `error' respects and modifies are
+- not used and that the program is exited even if STATUS is zero.
+-
+- - Function: void verr (int STATUS, const char *FORMAT, va_list)
+- The `verr' function is just like `err' except that the parameters
+- for the handling of the format string FORMAT are passed in as an
+- value of type `va_list'.
+-
+- - Function: void errx (int STATUS, const char *FORMAT, ...)
+- The `errx' function is roughly equivalent to a call like
+- error (status, 0, format, the parameters)
+-
+- except that the global variables `error' respects and modifies are
+- not used and that the program is exited even if STATUS is zero.
+- The difference to `err' is that no error number string is printed.
+-
+- - Function: void verrx (int STATUS, const char *FORMAT, va_list)
+- The `verrx' function is just like `errx' except that the
+- parameters for the handling of the format string FORMAT are passed
+- in as an value of type `va_list'.

+-Virtual Memory Allocation And Paging
+-************************************
+-
+- This chapter describes how processes manage and use memory in a
+-system that uses the GNU C library.
+-
+- The GNU C Library has several functions for dynamically allocating
+-virtual memory in various ways. They vary in generality and in
+-efficiency. The library also provides functions for controlling paging
+-and allocation of real memory.

+-
+-Process Memory Concepts
+-=======================
+-
+- One of the most basic resources a process has available to it is
+-memory. There are a lot of different ways systems organize memory, but
+-in a typical one, each process has one linear virtual address space,
+-with addresses running from zero to some huge maximum. It need not be
+-contiguous; i.e. not all of these addresses actually can be used to
+-store data.
+-
+- The virtual memory is divided into pages (4 kilobytes is typical).
+-Backing each page of virtual memory is a page of real memory (called a
+-"frame") or some secondary storage, usually disk space. The disk space
+-might be swap space or just some ordinary disk file. Actually, a page
+-of all zeroes sometimes has nothing at all backing it - there's just a
+-flag saying it is all zeroes.
+-
+- The same frame of real memory or backing store can back multiple
+-virtual pages belonging to multiple processes. This is normally the
+-case, for example, with virtual memory occupied by GNU C library code.
+-The same real memory frame containing the `printf' function backs a
+-virtual memory page in each of the existing processes that has a
+-`printf' call in its program.
+-
+- In order for a program to access any part of a virtual page, the page
+-must at that moment be backed by ("connected to") a real frame. But
+-because there is usually a lot more virtual memory than real memory, the
+-pages must move back and forth between real memory and backing store
+-regularly, coming into real memory when a process needs to access them
+-and then retreating to backing store when not needed anymore. This
+-movement is called "paging".
+-
+- When a program attempts to access a page which is not at that moment
+-backed by real memory, this is known as a "page fault". When a page
+-fault occurs, the kernel suspends the process, places the page into a
+-real page frame (this is called "paging in" or "faulting in"), then
+-resumes the process so that from the process' point of view, the page
+-was in real memory all along. In fact, to the process, all pages always
+-seem to be in real memory. Except for one thing: the elapsed execution
+-time of an instruction that would normally be a few nanoseconds is
+-suddenly much, much, longer (because the kernel normally has to do I/O
+-to complete the page-in). For programs sensitive to that, the functions
+-described in *Note Locking Pages:: can control it.
+-
+- Within each virtual address space, a process has to keep track of
+-what is at which addresses, and that process is called memory
+-allocation. Allocation usually brings to mind meting out scarce
+-resources, but in the case of virtual memory, that's not a major goal,
+-because there is generally much more of it than anyone needs. Memory
+-allocation within a process is mainly just a matter of making sure that
+-the same byte of memory isn't used to store two different things.
+-
+- Processes allocate memory in two major ways: by exec and
+-programmatically. Actually, forking is a third way, but it's not very
+-interesting. *Note Creating a Process::.
+-
+- Exec is the operation of creating a virtual address space for a
+-process, loading its basic program into it, and executing the program.
+-It is done by the "exec" family of functions (e.g. `execl'). The
+-operation takes a program file (an executable), it allocates space to
+-load all the data in the executable, loads it, and transfers control to
+-it. That data is most notably the instructions of the program (the
+-"text"), but also literals and constants in the program and even some
+-variables: C variables with the static storage class (*note Memory
+-Allocation and C::).
+-
+- Once that program begins to execute, it uses programmatic allocation
+-to gain additional memory. In a C program with the GNU C library, there
+-are two kinds of programmatic allocation: automatic and dynamic. *Note
+-Memory Allocation and C::.
+-
+- Memory-mapped I/O is another form of dynamic virtual memory
+-allocation. Mapping memory to a file means declaring that the contents
+-of certain range of a process' addresses shall be identical to the
+-contents of a specified regular file. The system makes the virtual
+-memory initially contain the contents of the file, and if you modify
+-the memory, the system writes the same modification to the file. Note
+-that due to the magic of virtual memory and page faults, there is no
+-reason for the system to do I/O to read the file, or allocate real
+-memory for its contents, until the program accesses the virtual memory.
+-*Note Memory-mapped I/O::.
+-
+- Just as it programmatically allocates memory, the program can
+-programmatically deallocate ("free") it. You can't free the memory
+-that was allocated by exec. When the program exits or execs, you might
+-say that all its memory gets freed, but since in both cases the address
+-space ceases to exist, the point is really moot. *Note Program
+-Termination::.
+-
+- A process' virtual address space is divided into segments. A
+-segment is a contiguous range of virtual addresses. Three important
+-segments are:
+-
+- * The "text segment" contains a program's instructions and literals
+- and static constants. It is allocated by exec and stays the same
+- size for the life of the virtual address space.
+-
+- * The "data segment" is working storage for the program. It can be
+- preallocated and preloaded by exec and the process can extend or
+- shrink it by calling functions as described in *Note Resizing the
+- Data Segment::. Its lower end is fixed.
+-
+- * The "stack segment" contains a program stack. It grows as the
+- stack grows, but doesn't shrink when the stack shrinks.

+-
+-Memory Allocation in C Programs
+--------------------------------
+-
+- The C language supports two kinds of memory allocation through the
+-variables in C programs:
+-
+- * "Static allocation" is what happens when you declare a static or
+- global variable. Each static or global variable defines one block
+- of space, of a fixed size. The space is allocated once, when your
+- program is started (part of the exec operation), and is never
+- freed.
+-
+- * "Automatic allocation" happens when you declare an automatic
+- variable, such as a function argument or a local variable. The
+- space for an automatic variable is allocated when the compound
+- statement containing the declaration is entered, and is freed when
+- that compound statement is exited.
+-
+- In GNU C, the size of the automatic storage can be an expression
+- that varies. In other C implementations, it must be a constant.
+-
+- A third important kind of memory allocation, "dynamic allocation",
+-is not supported by C variables but is available via GNU C library
+-functions.
+-
+-Dynamic Memory Allocation
+-.........................
+-
+- "Dynamic memory allocation" is a technique in which programs
+-determine as they are running where to store some information. You need
+-dynamic allocation when the amount of memory you need, or how long you
+-continue to need it, depends on factors that are not known before the
+-program runs.
+-
+- For example, you may need a block to store a line read from an input
+-file; since there is no limit to how long a line can be, you must
+-allocate the memory dynamically and make it dynamically larger as you
+-read more of the line.
+-
+- Or, you may need a block for each record or each definition in the
+-input data; since you can't know in advance how many there will be, you
+-must allocate a new block for each record or definition as you read it.
+-
+- When you use dynamic allocation, the allocation of a block of memory
+-is an action that the program requests explicitly. You call a function
+-or macro when you want to allocate space, and specify the size with an
+-argument. If you want to free the space, you do so by calling another
+-function or macro. You can do these things whenever you want, as often
+-as you want.
+-
+- Dynamic allocation is not supported by C variables; there is no
+-storage class "dynamic", and there can never be a C variable whose
+-value is stored in dynamically allocated space. The only way to get
+-dynamically allocated memory is via a system call (which is generally
+-via a GNU C library function call), and the only way to refer to
+-dynamically allocated space is through a pointer. Because it is less
+-convenient, and because the actual process of dynamic allocation
+-requires more computation time, programmers generally use dynamic
+-allocation only when neither static nor automatic allocation will serve.
+-
+- For example, if you want to allocate dynamically some space to hold a
+-`struct foobar', you cannot declare a variable of type `struct foobar'
+-whose contents are the dynamically allocated space. But you can
+-declare a variable of pointer type `struct foobar *' and assign it the
+-address of the space. Then you can use the operators `*' and `->' on
+-this pointer variable to refer to the contents of the space:
+-
+- {
+- struct foobar *ptr
+- = (struct foobar *) malloc (sizeof (struct foobar));
+- ptr->name = x;
+- ptr->next = current_foobar;
+- current_foobar = ptr;
+- }

+-------------------------
+-
+- The most general dynamic allocation facility is `malloc'. It allows
+-you to allocate blocks of memory of any size at any time, make them
+-bigger or smaller at any time, and free the blocks individually at any
+-time (or never).

+-Basic Memory Allocation
+-.......................
+-
+- To allocate a block of memory, call `malloc'. The prototype for
+-this function is in `stdlib.h'.
+-
+- - Function: void * malloc (size_t SIZE)
+- This function returns a pointer to a newly allocated block SIZE
+- bytes long, or a null pointer if the block could not be allocated.
+-
+- The contents of the block are undefined; you must initialize it
+-yourself (or use `calloc' instead; *note Allocating Cleared Space::).
+-Normally you would cast the value as a pointer to the kind of object
+-that you want to store in the block. Here we show an example of doing
+-so, and of initializing the space with zeros using the library function
+-`memset' (*note Copying and Concatenation::):
+-
+- struct foo *ptr;
+- ...
+- ptr = (struct foo *) malloc (sizeof (struct foo));
+- if (ptr == 0) abort ();
+- memset (ptr, 0, sizeof (struct foo));
+-
+- You can store the result of `malloc' into any pointer variable
+-without a cast, because ISO C automatically converts the type `void *'
+-to another type of pointer when necessary. But the cast is necessary
+-in contexts other than assignment operators or if you might want your
+-code to run in traditional C.
+-
+- Remember that when allocating space for a string, the argument to
+-`malloc' must be one plus the length of the string. This is because a
+-string is terminated with a null character that doesn't count in the
+-"length" of the string but does need space. For example:
+-
+- char *ptr;
+- ...
+- ptr = (char *) malloc (length + 1);
+-
+-*Note Representation of Strings::, for more information about this.

+-Examples of `malloc'
+-....................
+-
+- If no more space is available, `malloc' returns a null pointer. You
+-should check the value of _every_ call to `malloc'. It is useful to
+-write a subroutine that calls `malloc' and reports an error if the
+-value is a null pointer, returning only if the value is nonzero. This
+-function is conventionally called `xmalloc'. Here it is:
+-
+- void *
+- xmalloc (size_t size)
+- {
+- register void *value = malloc (size);
+- if (value == 0)
+- fatal ("virtual memory exhausted");
+- return value;
+- }
+-
+- Here is a real example of using `malloc' (by way of `xmalloc'). The
+-function `savestring' will copy a sequence of characters into a newly
+-allocated null-terminated string:
+-
+- char *
+- savestring (const char *ptr, size_t len)
+- {
+- register char *value = (char *) xmalloc (len + 1);
+- value[len] = '\0';
+- return (char *) memcpy (value, ptr, len);
+- }
+-
+- The block that `malloc' gives you is guaranteed to be aligned so
+-that it can hold any type of data. In the GNU system, the address is
+-always a multiple of eight on most systems, and a multiple of 16 on
+-64-bit systems. Only rarely is any higher boundary (such as a page
+-boundary) necessary; for those cases, use `memalign', `posix_memalign'
+-or `valloc' (*note Aligned Memory Blocks::).
+-
+- Note that the memory located after the end of the block is likely to
+-be in use for something else; perhaps a block already allocated by
+-another call to `malloc'. If you attempt to treat the block as longer
+-than you asked for it to be, you are liable to destroy the data that
+-`malloc' uses to keep track of its blocks, or you may destroy the
+-contents of another block. If you have already allocated a block and
+-discover you want it to be bigger, use `realloc' (*note Changing Block
+-Size::).

+-Characters for Input Editing
+-............................
+-
+- These special characters are active only in canonical input mode.
+-*Note Canonical or Not::.
+-
+- - Macro: int VEOF
+- This is the subscript for the EOF character in the special control
+- character array. `TERMIOS.c_cc[VEOF]' holds the character itself.
+-
+- The EOF character is recognized only in canonical input mode. It
+- acts as a line terminator in the same way as a newline character,
+- but if the EOF character is typed at the beginning of a line it
+- causes `read' to return a byte count of zero, indicating
+- end-of-file. The EOF character itself is discarded.
+-
+- Usually, the EOF character is `C-d'.
+-
+- - Macro: int VEOL
+- This is the subscript for the EOL character in the special control
+- character array. `TERMIOS.c_cc[VEOL]' holds the character itself.
+-
+- The EOL character is recognized only in canonical input mode. It
+- acts as a line terminator, just like a newline character. The EOL
+- character is not discarded; it is read as the last character in
+- the input line.
+-
+- You don't need to use the EOL character to make <RET> end a line.
+- Just set the ICRNL flag. In fact, this is the default state of
+- affairs.
+-
+- - Macro: int VEOL2
+- This is the subscript for the EOL2 character in the special control
+- character array. `TERMIOS.c_cc[VEOL2]' holds the character itself.
+-
+- The EOL2 character works just like the EOL character (see above),
+- but it can be a different character. Thus, you can specify two
+- characters to terminate an input line, by setting EOL to one of
+- them and EOL2 to the other.
+-
+- The EOL2 character is a BSD extension; it exists only on BSD
+- systems and the GNU system.
+-
+- - Macro: int VERASE
+- This is the subscript for the ERASE character in the special
+- control character array. `TERMIOS.c_cc[VERASE]' holds the
+- character itself.
+-
+- The ERASE character is recognized only in canonical input mode.
+- When the user types the erase character, the previous character
+- typed is discarded. (If the terminal generates multibyte
+- character sequences, this may cause more than one byte of input to
+- be discarded.) This cannot be used to erase past the beginning of
+- the current line of text. The ERASE character itself is discarded.
+-
+- Usually, the ERASE character is <DEL>.
+-
+- - Macro: int VWERASE
+- This is the subscript for the WERASE character in the special
+- control character array. `TERMIOS.c_cc[VWERASE]' holds the
+- character itself.
+-
+- The WERASE character is recognized only in canonical mode. It
+- erases an entire word of prior input, and any whitespace after it;
+- whitespace characters before the word are not erased.
+-
+- The definition of a "word" depends on the setting of the
+- `ALTWERASE' mode; *note Local Modes::.
+-
+- If the `ALTWERASE' mode is not set, a word is defined as a sequence
+- of any characters except space or tab.
+-
+- If the `ALTWERASE' mode is set, a word is defined as a sequence of
+- characters containing only letters, numbers, and underscores,
+- optionally followed by one character that is not a letter, number,
+- or underscore.
+-
+- The WERASE character is usually `C-w'.
+-
+- This is a BSD extension.
+-
+- - Macro: int VKILL
+- This is the subscript for the KILL character in the special control
+- character array. `TERMIOS.c_cc[VKILL]' holds the character itself.
+-
+- The KILL character is recognized only in canonical input mode.
+- When the user types the kill character, the entire contents of the
+- current line of input are discarded. The kill character itself is
+- discarded too.
+-
+- The KILL character is usually `C-u'.
+-
+- - Macro: int VREPRINT
+- This is the subscript for the REPRINT character in the special
+- control character array. `TERMIOS.c_cc[VREPRINT]' holds the
+- character itself.
+-
+- The REPRINT character is recognized only in canonical mode. It
+- reprints the current input line. If some asynchronous output has
+- come while you are typing, this lets you see the line you are
+- typing clearly again.
+-
+- The REPRINT character is usually `C-r'.
+-
+- This is a BSD extension.

+-Characters that Cause Signals
+-.............................
+-
+- These special characters may be active in either canonical or
+-noncanonical input mode, but only when the `ISIG' flag is set (*note
+-Local Modes::).
+-
+- - Macro: int VINTR
+- This is the subscript for the INTR character in the special control
+- character array. `TERMIOS.c_cc[VINTR]' holds the character itself.
+-
+- The INTR (interrupt) character raises a `SIGINT' signal for all
+- processes in the foreground job associated with the terminal. The
+- INTR character itself is then discarded. *Note Signal Handling::,
+- for more information about signals.
+-
+- Typically, the INTR character is `C-c'.
+-
+- - Macro: int VQUIT
+- This is the subscript for the QUIT character in the special control
+- character array. `TERMIOS.c_cc[VQUIT]' holds the character itself.
+-
+- The QUIT character raises a `SIGQUIT' signal for all processes in
+- the foreground job associated with the terminal. The QUIT
+- character itself is then discarded. *Note Signal Handling::, for
+- more information about signals.
+-
+- Typically, the QUIT character is `C-\'.
+-
+- - Macro: int VSUSP
+- This is the subscript for the SUSP character in the special control
+- character array. `TERMIOS.c_cc[VSUSP]' holds the character itself.
+-
+- The SUSP (suspend) character is recognized only if the
+- implementation supports job control (*note Job Control::). It
+- causes a `SIGTSTP' signal to be sent to all processes in the
+- foreground job associated with the terminal. The SUSP character
+- itself is then discarded. *Note Signal Handling::, for more
+- information about signals.
+-
+- Typically, the SUSP character is `C-z'.
+-
+- Few applications disable the normal interpretation of the SUSP
+-character. If your program does this, it should provide some other
+-mechanism for the user to stop the job. When the user invokes this
+-mechanism, the program should send a `SIGTSTP' signal to the process
+-group of the process, not just to the process itself. *Note Signaling
+-Another Process::.
+-
+- - Macro: int VDSUSP
+- This is the subscript for the DSUSP character in the special
+- control character array. `TERMIOS.c_cc[VDSUSP]' holds the
+- character itself.
+-
+- The DSUSP (suspend) character is recognized only if the
+- implementation supports job control (*note Job Control::). It
+- sends a `SIGTSTP' signal, like the SUSP character, but not right
+- away--only when the program tries to read it as input. Not all
+- systems with job control support DSUSP; only BSD-compatible
+- systems (including the GNU system).
+-
+- *Note Signal Handling::, for more information about signals.
+-
+- Typically, the DSUSP character is `C-y'.

+-Special Characters for Flow Control
+-...................................
+-
+- These special characters may be active in either canonical or
+-noncanonical input mode, but their use is controlled by the flags
+-`IXON' and `IXOFF' (*note Input Modes::).
+-
+- - Macro: int VSTART
+- This is the subscript for the START character in the special
+- control character array. `TERMIOS.c_cc[VSTART]' holds the
+- character itself.
+-
+- The START character is used to support the `IXON' and `IXOFF'
+- input modes. If `IXON' is set, receiving a START character resumes
+- suspended output; the START character itself is discarded. If
+- `IXANY' is set, receiving any character at all resumes suspended
+- output; the resuming character is not discarded unless it is the
+- START character. `IXOFF' is set, the system may also transmit
+- START characters to the terminal.
+-
+- The usual value for the START character is `C-q'. You may not be
+- able to change this value--the hardware may insist on using `C-q'
+- regardless of what you specify.
+-
+- - Macro: int VSTOP
+- This is the subscript for the STOP character in the special control
+- character array. `TERMIOS.c_cc[VSTOP]' holds the character itself.
+-
+- The STOP character is used to support the `IXON' and `IXOFF' input
+- modes. If `IXON' is set, receiving a STOP character causes output
+- to be suspended; the STOP character itself is discarded. If
+- `IXOFF' is set, the system may also transmit STOP characters to the
+- terminal, to prevent the input queue from overflowing.
+-
+- The usual value for the STOP character is `C-s'. You may not be
+- able to change this value--the hardware may insist on using `C-s'
+- regardless of what you specify.

+-
+- - Macro: int VLNEXT
+- This is the subscript for the LNEXT character in the special
+- control character array. `TERMIOS.c_cc[VLNEXT]' holds the
+- character itself.
+-
+- The LNEXT character is recognized only when `IEXTEN' is set, but in
+- both canonical and noncanonical mode. It disables any special
+- significance of the next character the user types. Even if the
+- character would normally perform some editing function or generate
+- a signal, it is read as a plain character. This is the analogue
+- of the `C-q' command in Emacs. "LNEXT" stands for "literal next."
+-
+- The LNEXT character is usually `C-v'.
+-
+- - Macro: int VDISCARD
+- This is the subscript for the DISCARD character in the special
+- control character array. `TERMIOS.c_cc[VDISCARD]' holds the
+- character itself.
+-
+- The DISCARD character is recognized only when `IEXTEN' is set, but
+- in both canonical and noncanonical mode. Its effect is to toggle
+- the discard-output flag. When this flag is set, all program
+- output is discarded. Setting the flag also discards all output
+- currently in the output buffer. Typing any other character resets
+- the flag.
+-
+- - Macro: int VSTATUS
+- This is the subscript for the STATUS character in the special
+- control character array. `TERMIOS.c_cc[VSTATUS]' holds the
+- character itself.
+-
+- The STATUS character's effect is to print out a status message
+- about how the current process is running.
+-
+- The STATUS character is recognized only in canonical mode, and
+- only if `NOKERNINFO' is not set.

+-File: libc.info, Node: Noncanonical Input, Prev: Special Characters, Up: Terminal Modes
+-
+-Noncanonical Input
+-------------------
+-
+- In noncanonical input mode, the special editing characters such as
+-ERASE and KILL are ignored. The system facilities for the user to edit
+-input are disabled in noncanonical mode, so that all input characters
+-(unless they are special for signal or flow-control purposes) are passed
+-to the application program exactly as typed. It is up to the
+-application program to give the user ways to edit the input, if
+-appropriate.
+-
+- Noncanonical mode offers special parameters called MIN and TIME for
+-controlling whether and how long to wait for input to be available. You
+-can even use them to avoid ever waiting--to return immediately with
+-whatever input is available, or with no input.
+-
+- The MIN and TIME are stored in elements of the `c_cc' array, which
+-is a member of the `struct termios' structure. Each element of this
+-array has a particular role, and each element has a symbolic constant
+-that stands for the index of that element. `VMIN' and `VMAX' are the
+-names for the indices in the array of the MIN and TIME slots.
+-
+- - Macro: int VMIN
+- This is the subscript for the MIN slot in the `c_cc' array. Thus,
+- `TERMIOS.c_cc[VMIN]' is the value itself.
+-
+- The MIN slot is only meaningful in noncanonical input mode; it
+- specifies the minimum number of bytes that must be available in the
+- input queue in order for `read' to return.
+-
+- - Macro: int VTIME
+- This is the subscript for the TIME slot in the `c_cc' array. Thus,
+- `TERMIOS.c_cc[VTIME]' is the value itself.
+-
+- The TIME slot is only meaningful in noncanonical input mode; it
+- specifies how long to wait for input before returning, in units of
+- 0.1 seconds.
+-
+- The MIN and TIME values interact to determine the criterion for when
+-`read' should return; their precise meanings depend on which of them
+-are nonzero. There are four possible cases:
+-
+- * Both TIME and MIN are nonzero.
+-
+- In this case, TIME specifies how long to wait after each input
+- character to see if more input arrives. After the first character
+- received, `read' keeps waiting until either MIN bytes have arrived
+- in all, or TIME elapses with no further input.
+-
+- `read' always blocks until the first character arrives, even if
+- TIME elapses first. `read' can return more than MIN characters if
+- more than MIN happen to be in the queue.
+-
+- * Both MIN and TIME are zero.
+-
+- In this case, `read' always returns immediately with as many
+- characters as are available in the queue, up to the number
+- requested. If no input is immediately available, `read' returns a
+- value of zero.
+-
+- * MIN is zero but TIME has a nonzero value.
+-
+- In this case, `read' waits for time TIME for input to become
+- available; the availability of a single byte is enough to satisfy
+- the read request and cause `read' to return. When it returns, it
+- returns as many characters as are available, up to the number
+- requested. If no input is available before the timer expires,
+- `read' returns a value of zero.
+-
+- * TIME is zero but MIN has a nonzero value.
+-
+- In this case, `read' waits until at least MIN bytes are available
+- in the queue. At that time, `read' returns as many characters as
+- are available, up to the number requested. `read' can return more
+- than MIN characters if more than MIN happen to be in the queue.
+-
+- What happens if MIN is 50 and you ask to read just 10 bytes?
+-Normally, `read' waits until there are 50 bytes in the buffer (or, more
+-generally, the wait condition described above is satisfied), and then
+-reads 10 of them, leaving the other 40 buffered in the operating system
+-for a subsequent call to `read'.
+-
+- *Portability note:* On some systems, the MIN and TIME slots are
+-actually the same as the EOF and EOL slots. This causes no serious
+-problem because the MIN and TIME slots are used only in noncanonical
+-input and the EOF and EOL slots are used only in canonical input, but it
+-isn't very clean. The GNU library allocates separate slots for these
+-uses.
+-
+- - Function: void cfmakeraw (struct termios *TERMIOS-P)
+- This function provides an easy way to set up `*TERMIOS-P' for what
+- has traditionally been called "raw mode" in BSD. This uses
+- noncanonical input, and turns off most processing to give an
+- unmodified channel to the terminal.
+-

+-Line Control Functions
+-======================
+-
+- These functions perform miscellaneous control actions on terminal
+-devices. As regards terminal access, they are treated like doing
+-output: if any of these functions is used by a background process on its
+-controlling terminal, normally all processes in the process group are
+-sent a `SIGTTOU' signal. The exception is if the calling process
+-itself is ignoring or blocking `SIGTTOU' signals, in which case the
+-operation is performed and no signal is sent. *Note Job Control::.
+-
+- - Function: int tcsendbreak (int FILEDES, int DURATION)
+- This function generates a break condition by transmitting a stream
+- of zero bits on the terminal associated with the file descriptor
+- FILEDES. The duration of the break is controlled by the DURATION
+- argument. If zero, the duration is between 0.25 and 0.5 seconds.
+- The meaning of a nonzero value depends on the operating system.
+-
+- This function does nothing if the terminal is not an asynchronous
+- serial data port.
+-
+- The return value is normally zero. In the event of an error, a
+- value of -1 is returned. The following `errno' error conditions
+- are defined for this function:
+-
+- `EBADF'
+- The FILEDES is not a valid file descriptor.
+-
+- `ENOTTY'
+- The FILEDES is not associated with a terminal device.
+-
+- - Function: int tcdrain (int FILEDES)
+- The `tcdrain' function waits until all queued output to the
+- terminal FILEDES has been transmitted.
+-
+- This function is a cancellation point in multi-threaded programs.
+- This is a problem if the thread allocates some resources (like
+- memory, file descriptors, semaphores or whatever) at the time
+- `tcdrain' is called. If the thread gets canceled these resources
+- stay allocated until the program ends. To avoid this calls to
+- `tcdrain' should be protected using cancellation handlers.
+-
+- The return value is normally zero. In the event of an error, a
+- value of -1 is returned. The following `errno' error conditions
+- are defined for this function:
+-
+- `EBADF'
+- The FILEDES is not a valid file descriptor.
+-
+- `ENOTTY'
+- The FILEDES is not associated with a terminal device.
+-
+- `EINTR'
+- The operation was interrupted by delivery of a signal. *Note
+- Interrupted Primitives::.
+-
+- - Function: int tcflush (int FILEDES, int QUEUE)
+- The `tcflush' function is used to clear the input and/or output
+- queues associated with the terminal file FILEDES. The QUEUE
+- argument specifies which queue(s) to clear, and can be one of the
+- following values:
+-
+- `TCIFLUSH'
+- Clear any input data received, but not yet read.
+-
+- `TCOFLUSH'
+- Clear any output data written, but not yet transmitted.
+-
+- `TCIOFLUSH'
+- Clear both queued input and output.

+- A bad value was supplied as the QUEUE argument.
+-
+- It is unfortunate that this function is named `tcflush', because
+- the term "flush" is normally used for quite another
+- operation--waiting until all output is transmitted--and using it
+- for discarding input or output would be confusing. Unfortunately,
+- the name `tcflush' comes from POSIX and we cannot change it.
+-
+- - Function: int tcflow (int FILEDES, int ACTION)
+- The `tcflow' function is used to perform operations relating to
+- XON/XOFF flow control on the terminal file specified by FILEDES.
+-
+- The ACTION argument specifies what operation to perform, and can

+- {
+- struct termios tattr;
+- char *name;
+-
+- /* Make sure stdin is a terminal. */
+- if (!isatty (STDIN_FILENO))
+- {
+- fprintf (stderr, "Not a terminal.\n");
+- exit (EXIT_FAILURE);
+- }
+-
+- /* Save the terminal attributes so we can restore them later. */
+- tcgetattr (STDIN_FILENO, &saved_attributes);
+- atexit (reset_input_mode);
+-
+- /* Set the funny terminal modes. */
+- tcgetattr (STDIN_FILENO, &tattr);
+- tattr.c_lflag &= ~(ICANON|ECHO); /* Clear ICANON and ECHO. */
+- tattr.c_cc[VMIN] = 1;
+- tattr.c_cc[VTIME] = 0;

+- if (c == '\004') /* `C-d' */
+- break;
+- else
+- putchar (c);
+- }
+-
+- return EXIT_SUCCESS;
+- }
+-
+- This program is careful to restore the original terminal modes before
+-exiting or terminating with a signal. It uses the `atexit' function
+-(*note Cleanups on Exit::) to make sure this is done by `exit'.
+-
+- The shell is supposed to take care of resetting the terminal modes

+-The above example does so.

+-Pseudo-Terminals
+-================
+-
+- A "pseudo-terminal" is a special interprocess communication channel
+-that acts like a terminal. One end of the channel is called the
+-"master" side or "master pseudo-terminal device", the other side is
+-called the "slave" side. Data written to the master side is received
+-by the slave side as if it was the result of a user typing at an
+-ordinary terminal, and data written to the slave side is sent to the
+-master side as if it was written on an ordinary terminal.
+-
+- Pseudo terminals are the way programs like `xterm' and `emacs'
+-implement their terminal emulation functionality.

+-
+-Allocating Pseudo-Terminals
+----------------------------
+-
+- This subsection describes functions for allocating a pseudo-terminal,
+-and for making this pseudo-terminal available for actual use. These
+-functions are declared in the header file `stdlib.h'.
+-
+- - Function: int getpt (void)
+- The `getpt' function returns a new file descriptor for the next
+- available master pseudo-terminal. The normal return value from
+- `getpt' is a non-negative integer file descriptor. In the case of
+- an error, a value of -1 is returned instead. The following
+- `errno' conditions are defined for this function:
+-
+- `ENOENT'
+- There are no free master pseudo-terminals available.
+-
+- This function is a GNU extension.
+-
+- - Function: int grantpt (int FILEDES)
+- The `grantpt' function changes the ownership and access permission
+- of the slave pseudo-terminal device corresponding to the master
+- pseudo-terminal device associated with the file descriptor
+- FILEDES. The owner is set from the real user ID of the calling
+- process (*note Process Persona::), and the group is set to a
+- special group (typically "tty") or from the real group ID of the
+- calling process. The access permission is set such that the file
+- is both readable and writable by the owner and only writable by
+- the group.
+-
+- On some systems this function is implemented by invoking a special
+- `setuid' root program (*note How Change Persona::). As a
+- consequence, installing a signal handler for the `SIGCHLD' signal
+- (*note Job Control Signals::) may interfere with a call to
+- `grantpt'.
+-
+- The normal return value from `grantpt' is 0; a value of -1 is
+- returned in case of failure. The following `errno' error
+- conditions are defined for this function:
+-
+- `EBADF'
+- The FILEDES argument is not a valid file descriptor.
+-
+- `EINVAL'
+- The FILEDES argument is not associated with a master
+- pseudo-terminal device.
+-
+- `EACCES'
+- The slave pseudo-terminal device corresponding to the master
+- associated with FILEDES could not be accessed.
+-
+-
+- - Function: int unlockpt (int FILEDES)
+- The `unlockpt' function unlocks the slave pseudo-terminal device
+- corresponding to the master pseudo-terminal device associated with
+- the file descriptor FILEDES. On many systems, the slave can only
+- be opened after unlocking, so portable applications should always
+- call `unlockpt' before trying to open the slave.
+-
+- The normal return value from `unlockpt' is 0; a value of -1 is
+- returned in case of failure. The following `errno' error
+- conditions are defined for this function:
+-
+- `EBADF'
+- The FILEDES argument is not a valid file descriptor.
+-
+- `EINVAL'
+- The FILEDES argument is not associated with a master
+- pseudo-terminal device.
+-
+- - Function: char * ptsname (int FILEDES)
+- If the file descriptor FILEDES is associated with a master
+- pseudo-terminal device, the `ptsname' function returns a pointer
+- to a statically-allocated, null-terminated string containing the
+- file name of the associated slave pseudo-terminal file. This
+- string might be overwritten by subsequent calls to `ptsname'.
+-
+- - Function: int ptsname_r (int FILEDES, char *BUF, size_t LEN)
+- The `ptsname_r' function is similar to the `ptsname' function
+- except that it places its result into the user-specified buffer
+- starting at BUF with length LEN.
+-
+- This function is a GNU extension.
+-
+- *Portability Note:* On System V derived systems, the file returned
+-by the `ptsname' and `ptsname_r' functions may be STREAMS-based, and
+-therefore require additional processing after opening before it
+-actually behaves as a pseudo terminal.
+-
+- Typical usage of these functions is illustrated by the following
+-example:
+- int
+- open_pty_pair (int *amaster, int *aslave)
+- {
+- int master, slave;
+- char *name;
+-
+- master = getpt ();
+- if (master < 0)
+- return 0;
+-
+- if (grantpt (master) < 0 || unlockpt (master) < 0)
+- goto close_master;
+- name = ptsname (master);
+- if (name == NULL)
+- goto close_master;
+-
+- slave = open (name, O_RDWR);
+- if (slave == -1)
+- goto close_master;
+-
+- if (isastream (slave))
+- {
+- if (ioctl (slave, I_PUSH, "ptem") < 0
+- || ioctl (slave, I_PUSH, "ldterm") < 0)
+- goto close_slave;
+- }
+-
+- *amaster = master;
+- *aslave = slave;
+- return 1;
+-
+- close_slave:
+- close (slave);
+-
+- close_master:
+- close (master);
+- return 0;
+- }
+-
+-\1f
+-File: libc.info, Node: Pseudo-Terminal Pairs, Prev: Allocation, Up: Pseudo-Terminals
+-
+-Opening a Pseudo-Terminal Pair
+-------------------------------
+-
+- These functions, derived from BSD, are available in the separate
+-`libutil' library, and declared in `pty.h'.
+-
+- - Function: int openpty (int *AMASTER, int *ASLAVE, char *NAME, struct
+- termios *TERMP, struct winsize *WINP)
+- This function allocates and opens a pseudo-terminal pair,
+- returning the file descriptor for the master in *AMASTER, and the
+- file descriptor for the slave in *ASLAVE. If the argument NAME is
+- not a null pointer, the file name of the slave pseudo-terminal
+- device is stored in `*name'. If TERMP is not a null pointer, the
+- terminal attributes of the slave are set to the ones specified in
+- the structure that TERMP points to (*note Terminal Modes::).
+- Likewise, if the WINP is not a null pointer, the screen size of
+- the slave is set to the values specified in the structure that
+- WINP points to.
+-
+- The normal return value from `openpty' is 0; a value of -1 is
+- returned in case of failure. The following `errno' conditions are
+- defined for this function:
+-
+- `ENOENT'
+- There are no free pseudo-terminal pairs available.
+-
+- *Warning:* Using the `openpty' function with NAME not set to
+- `NULL' is *very dangerous* because it provides no protection
+- against overflowing the string NAME. You should use the `ttyname'
+- function on the file descriptor returned in *SLAVE to find out the
+- file name of the slave pseudo-terminal device instead.
+-
+- - Function: int forkpty (int *AMASTER, char *NAME, struct termios
+- *TERMP, struct winsize *WINP)
+- This function is similar to the `openpty' function, but in
+- addition, forks a new process (*note Creating a Process::) and
+- makes the newly opened slave pseudo-terminal device the
+- controlling terminal (*note Controlling Terminal::) for the child
+- process.
+-
+- If the operation is successful, there are then both parent and
+- child processes and both see `forkpty' return, but with different
+- values: it returns a value of 0 in the child process and returns
+- the child's process ID in the parent process.
+-
+- If the allocation of a pseudo-terminal pair or the process creation
+- failed, `forkpty' returns a value of -1 in the parent process.
+-
+- *Warning:* The `forkpty' function has the same problems with
+- respect to the NAME argument as `openpty'.

+-Syslog
+-******
+-
+- This chapter describes facilities for issuing and logging messages of
+-system administration interest. This chapter has nothing to do with
+-programs issuing messages to their own users or keeping private logs
+-(One would typically do that with the facilities described in *Note I/O
+-on Streams::).
+-
+- Most systems have a facility called "Syslog" that allows programs to
+-submit messages of interest to system administrators and can be
+-configured to pass these messages on in various ways, such as printing
+-on the console, mailing to a particular person, or recording in a log
+-file for future reference.
+-
+- A program uses the facilities in this chapter to submit such
+-messages.

+-
+-Overview of Syslog
+-==================
+-
+- System administrators have to deal with lots of different kinds of
+-messages from a plethora of subsystems within each system, and usually
+-lots of systems as well. For example, an FTP server might report every
+-connection it gets. The kernel might report hardware failures on a disk
+-drive. A DNS server might report usage statistics at regular intervals.
+-
+- Some of these messages need to be brought to a system administrator's
+-attention immediately. And it may not be just any system administrator
+-- there may be a particular system administrator who deals with a
+-particular kind of message. Other messages just need to be recorded for
+-future reference if there is a problem. Still others may need to have
+-information extracted from them by an automated process that generates
+-monthly reports.
+-
+- To deal with these messages, most Unix systems have a facility called
+-"Syslog." It is generally based on a daemon called "Syslogd" Syslogd
+-listens for messages on a Unix domain socket named `/dev/log'. Based
+-on classification information in the messages and its configuration
+-file (usually `/etc/syslog.conf'), Syslogd routes them in various ways.
+-Some of the popular routings are:
+-
+- * Write to the system console
+-
+- * Mail to a specific user
+-
+- * Write to a log file
+-
+- * Pass to another daemon
+-
+- * Discard
+-
+- Syslogd can also handle messages from other systems. It listens on
+-the `syslog' UDP port as well as the local socket for messages.
+-
+- Syslog can handle messages from the kernel itself. But the kernel
+-doesn't write to `/dev/log'; rather, another daemon (sometimes called
+-"Klogd") extracts messages from the kernel and passes them on to Syslog
+-as any other process would (and it properly identifies them as messages
+-from the kernel).
+-
+- Syslog can even handle messages that the kernel issued before
+-Syslogd or Klogd was running. A Linux kernel, for example, stores
+-startup messages in a kernel message ring and they are normally still
+-there when Klogd later starts up. Assuming Syslogd is running by the
+-time Klogd starts, Klogd then passes everything in the message ring to
+-it.
+-
+- In order to classify messages for disposition, Syslog requires any
+-process that submits a message to it to provide two pieces of
+-classification information with it:
+-
+-facility
+- This identifies who submitted the message. There are a small
+- number of facilities defined. The kernel, the mail subsystem, and
+- an FTP server are examples of recognized facilities. For the
+- complete list, *Note syslog; vsyslog::. Keep in mind that these
+- are essentially arbitrary classifications. "Mail subsystem"
+- doesn't have any more meaning than the system administrator gives
+- to it.
+-
+-priority
+- This tells how important the content of the message is. Examples
+- of defined priority values are: debug, informational, warning,
+- critical. For the complete list, *Note syslog; vsyslog::. Except
+- for the fact that the priorities have a defined order, the meaning
+- of each of these priorities is entirely determined by the system
+- administrator.
+-
+- A "facility/priority" is a number that indicates both the facility
+-and the priority.
+-
+- *Warning:* This terminology is not universal. Some people use
+-"level" to refer to the priority and "priority" to refer to the
+-combination of facility and priority. A Linux kernel has a concept of a
+-message "level," which corresponds both to a Syslog priority and to a
+-Syslog facility/priority (It can be both because the facility code for
+-the kernel is zero, and that makes priority and facility/priority the
+-same value).
+-
+- The GNU C library provides functions to submit messages to Syslog.
+-They do it by writing to the `/dev/log' socket. *Note Submitting
+-Syslog Messages::.
+-
+- The GNU C library functions only work to submit messages to the
+-Syslog facility on the same system. To submit a message to the Syslog
+-facility on another system, use the socket I/O functions to write a UDP
+-datagram to the `syslog' UDP port on that system. *Note Sockets::.

+-* closelog:: Close connection to Syslog

+-
+-openlog
+--------
+-
+- The symbols referred to in this section are declared in the file
+-`syslog.h'.
+-
+- - Function: void openlog (const char *IDENT, int OPTION, int FACILITY)
+- `openlog' opens or reopens a connection to Syslog in preparation
+- for submitting messages.
+-
+- IDENT is an arbitrary identification string which future `syslog'
+- invocations will prefix to each message. This is intended to
+- identify the source of the message, and people conventionally set
+- it to the name of the program that will submit the messages.
+-
+- If IDENT is NULL, or if `openlog' is not called, the default
+- identification string used in Syslog messages will be the program
+- name, taken from argv[0].
+-
+- Please note that the string pointer IDENT will be retained
+- internally by the Syslog routines. You must not free the memory
+- that IDENT points to. It is also dangerous to pass a reference to
+- an automatic variable since leaving the scope would mean ending the
+- lifetime of the variable. If you want to change the IDENT string,
+- you must call `openlog' again; overwriting the string pointed to by
+- IDENT is not thread-safe.
+-
+- You can cause the Syslog routines to drop the reference to IDENT
+- and go back to the default string (the program name taken from
+- argv[0]), by calling `closelog': *Note closelog::.
+-
+- In particular, if you are writing code for a shared library that
+- might get loaded and then unloaded (e.g. a PAM module), and you
+- use `openlog', you must call `closelog' before any point where
+- your library might get unloaded, as in this example:
+-
+- #include <syslog.h>
+-
+- void
+- shared_library_function (void)
+- {
+- openlog ("mylibrary", option, priority);
+-
+- syslog (LOG_INFO, "shared library has been invoked");
+-
+- closelog ();
+- }
+-
+- Without the call to `closelog', future invocations of `syslog' by
+- the program using the shared library may crash, if the library gets
+- unloaded and the memory containing the string `"mylibrary"' becomes
+- unmapped. This is a limitation of the BSD syslog interface.
+-
+- `openlog' may or may not open the `/dev/log' socket, depending on
+- OPTION. If it does, it tries to open it and connect it as a
+- stream socket. If that doesn't work, it tries to open it and
+- connect it as a datagram socket. The socket has the "Close on
+- Exec" attribute, so the kernel will close it if the process
+- performs an exec.
+-
+- You don't have to use `openlog'. If you call `syslog' without
+- having called `openlog', `syslog' just opens the connection
+- implicitly and uses defaults for the information in IDENT and
+- OPTIONS.
+-
+- OPTIONS is a bit string, with the bits as defined by the following
+- single bit masks:
+-
+- `LOG_PERROR'
+- If on, `openlog' sets up the connection so that any `syslog'
+- on this connection writes its message to the calling process'
+- Standard Error stream in addition to submitting it to Syslog.
+- If off, `syslog' does not write the message to Standard
+- Error.
+-
+- `LOG_CONS'
+- If on, `openlog' sets up the connection so that a `syslog' on
+- this connection that fails to submit a message to Syslog
+- writes the message instead to system console. If off,
+- `syslog' does not write to the system console (but of course
+- Syslog may write messages it receives to the console).
+-
+- `LOG_PID'
+- When on, `openlog' sets up the connection so that a `syslog'
+- on this connection inserts the calling process' Process ID
+- (PID) into the message. When off, `openlog' does not insert
+- the PID.
+-
+- `LOG_NDELAY'
+- When on, `openlog' opens and connects the `/dev/log' socket.
+- When off, a future `syslog' call must open and connect the
+- socket.
+-
+- *Portability note:* In early systems, the sense of this bit
+- was exactly the opposite.
+-
+- `LOG_ODELAY'
+- This bit does nothing. It exists for backward compatibility.
+-
+- If any other bit in OPTIONS is on, the result is undefined.
+-
+- FACILITY is the default facility code for this connection. A
+- `syslog' on this connection that specifies default facility causes
+- this facility to be associated with the message. See `syslog' for
+- possible values. A value of zero means the default default, which
+- is `LOG_USER'.
+-
+- If a Syslog connection is already open when you call `openlog',
+- `openlog' "reopens" the connection. Reopening is like opening
+- except that if you specify zero for the default facility code, the
+- default facility code simply remains unchanged and if you specify
+- LOG_NDELAY and the socket is already open and connected, `openlog'
+- just leaves it that way.

+----------------
+-
+- The symbols referred to in this section are declared in the file
+-`syslog.h'.
+-
+- - Function: void syslog (int FACILITY_PRIORITY, char *FORMAT, ...)
+- `syslog' submits a message to the Syslog facility. It does this by
+- writing to the Unix domain socket `/dev/log'.
+-
+- `syslog' submits the message with the facility and priority
+- indicated by FACILITY_PRIORITY. The macro `LOG_MAKEPRI' generates
+- a facility/priority from a facility and a priority, as in the
+- following example:
+-
+- LOG_MAKEPRI(LOG_USER, LOG_WARNING)
+-
+- The possible values for the facility code are (macros):
+-
+- `LOG_USER'
+- A miscellaneous user process
+-
+- `LOG_MAIL'
+- Mail
+-
+- `LOG_DAEMON'
+- A miscellaneous system daemon
+-
+- `LOG_AUTH'

+-
+- `LOG_CRON'
+- Cron and At

+- `LOG_LOCAL5'
+- Locally defined
+-
+- `LOG_LOCAL6'
+- Locally defined
+-
+- `LOG_LOCAL7'
+- Locally defined
+-
+- Results are undefined if the facility code is anything else.
+-
+- *note:* `syslog' recognizes one other facility code: that of the
+- kernel. But you can't specify that facility code with these
+- functions. If you try, it looks the same to `syslog' as if you are
+- requesting the default facility. But you wouldn't want to anyway,
+- because any program that uses the GNU C library is not the kernel.
+-
+- You can use just a priority code as FACILITY_PRIORITY. In that
+- case, `syslog' assumes the default facility established when the
+- Syslog connection was opened. *Note Syslog Example::.
+-
+- The possible values for the priority code are (macros):
+-
+- `LOG_EMERG'
+- The message says the system is unusable.
+-
+- `LOG_ALERT'
+- Action on the message must be taken immediately.
+-
+- `LOG_CRIT'
+- The message states a critical condition.
+-
+- `LOG_ERR'
+- The message describes an error.
+-
+- `LOG_WARNING'
+- The message is a warning.
+-
+- `LOG_NOTICE'
+- The message describes a normal but important event.
+-
+- `LOG_INFO'
+- The message is purely informational.
+-
+- `LOG_DEBUG'
+- The message is only for debugging purposes.
+-
+- Results are undefined if the priority code is anything else.
+-
+- If the process does not presently have a Syslog connection open
+- (i.e. it did not call `openlog'), `syslog' implicitly opens the
+- connection the same as `openlog' would, with the following defaults
+- for information that would otherwise be included in an `openlog'
+- call: The default identification string is the program name. The
+- default default facility is `LOG_USER'. The default for all the
+- connection options in OPTIONS is as if those bits were off.
+- `syslog' leaves the Syslog connection open.
+-
+- If the `dev/log' socket is not open and connected, `syslog' opens
+- and connects it, the same as `openlog' with the `LOG_NDELAY'
+- option would.
+-
+- `syslog' leaves `/dev/log' open and connected unless its attempt
+- to send the message failed, in which case `syslog' closes it (with
+- the hope that a future implicit open will restore the Syslog
+- connection to a usable state).
+-
+- Example:
+-
+-
+- #include <syslog.h>
+- syslog (LOG_MAKEPRI(LOG_LOCAL1, LOG_ERROR),
+- "Unable to make network connection to %s. Error=%m", host);
+-
+-
+- - Function: void vsyslog (int FACILITY_PRIORITY, char *FORMAT, va_list
+- arglist)
+- This is functionally identical to `syslog', with the BSD style
+- variable length argument.

+---------
+-
+- The symbols referred to in this section are declared in the file
+-`syslog.h'.
+-
+- - Function: void closelog (void)
+- `closelog' closes the current Syslog connection, if there is one.
+- This includes closing the `dev/log' socket, if it is open.
+- `closelog' also sets the identification string for Syslog messages
+- back to the default, if `openlog' was called with a non-NULL
+- argument to IDENT. The default identification string is the
+- program name taken from argv[0].
+-
+- If you are writing shared library code that uses `openlog' to
+- generate custom syslog output, you should use `closelog' to drop
+- the GNU C library's internal reference to the IDENT pointer when
+- you are done. Please read the section on `openlog' for more
+- information: *Note openlog::.
+-
+- `closelog' does not flush any buffers. You do not have to call
+- `closelog' before re-opening a Syslog connection with `initlog'.
+- Syslog connections are automatically closed on exec or exit.

+-setlogmask
+-----------
+-
+- The symbols referred to in this section are declared in the file
+-`syslog.h'.
+-
+- - Function: int setlogmask (int MASK)
+- `setlogmask' sets a mask (the "logmask") that determines which
+- future `syslog' calls shall be ignored. If a program has not
+- called `setlogmask', `syslog' doesn't ignore any calls. You can
+- use `setlogmask' to specify that messages of particular priorities
+- shall be ignored in the future.
+-
+- A `setlogmask' call overrides any previous `setlogmask' call.
+-
+- Note that the logmask exists entirely independently of opening and
+- closing of Syslog connections.
+-
+- Setting the logmask has a similar effect to, but is not the same
+- as, configuring Syslog. The Syslog configuration may cause Syslog
+- to discard certain messages it receives, but the logmask causes
+- certain messages never to get submitted to Syslog in the first
+- place.
+-
+- MASK is a bit string with one bit corresponding to each of the
+- possible message priorities. If the bit is on, `syslog' handles
+- messages of that priority normally. If it is off, `syslog'
+- discards messages of that priority. Use the message priority
+- macros described in *Note syslog; vsyslog:: and the `LOG_MASK' to
+- construct an appropriate MASK value, as in this example:
+-
+- LOG_MASK(LOG_EMERG) | LOG_MASK(LOG_ERROR)
+-
+- or
+-
+- ~(LOG_MASK(LOG_INFO))
+-
+- There is also a `LOG_UPTO' macro, which generates a mask with the
+- bits on for a certain priority and all priorities above it:
+-
+- LOG_UPTO(LOG_ERROR)
+-
+- The unfortunate naming of the macro is due to the fact that
+- internally, higher numbers are used for lower message priorities.

+---------------
+-
+- Here is an example of `openlog', `syslog', and `closelog':

+- This example sets the logmask so that debug and informational
+-messages get discarded without ever reaching Syslog. So the second
+-`syslog' in the example does nothing.

+-***********
+-
+- This chapter contains information about functions for performing
+-mathematical computations, such as trigonometric functions. Most of
+-these functions have prototypes declared in the header file `math.h'.
+-The complex-valued functions are defined in `complex.h'.
+-
+- All mathematical functions which take a floating-point argument have
+-three variants, one each for `double', `float', and `long double'
+-arguments. The `double' versions are mostly defined in ISO C89. The
+-`float' and `long double' versions are from the numeric extensions to C
+-included in ISO C99.
+-
+- Which of the three versions of a function should be used depends on
+-the situation. For most calculations, the `float' functions are the
+-fastest. On the other hand, the `long double' functions have the
+-highest precision. `double' is somewhere in between. It is usually
+-wise to pick the narrowest type that can accommodate your data. Not
+-all machines have a distinct `long double' type; it may be the same as
+-`double'.

+-Predefined Mathematical Constants
+-=================================
+-
+- The header `math.h' defines several useful mathematical constants.
+-All values are defined as preprocessor macros starting with `M_'. The
+-values provided are:
+-
+-`M_E'
+- The base of natural logarithms.
+-
+-`M_LOG2E'
+- The logarithm to base `2' of `M_E'.
+-
+-`M_LOG10E'
+- The logarithm to base `10' of `M_E'.
+-
+-`M_LN2'
+- The natural logarithm of `2'.
+-
+-`M_LN10'
+- The natural logarithm of `10'.
+-
+-`M_PI'
+- Pi, the ratio of a circle's circumference to its diameter.
+-
+-`M_PI_2'
+- Pi divided by two.
+-
+-`M_PI_4'
+- Pi divided by four.
+-
+-`M_1_PI'
+- The reciprocal of pi (1/pi)
+-
+-`M_2_PI'
+- Two times the reciprocal of pi.
+-
+-`M_2_SQRTPI'
+- Two times the reciprocal of the square root of pi.
+-
+-`M_SQRT2'
+- The square root of two.
+-
+-`M_SQRT1_2'
+- The reciprocal of the square root of two (also the square root of
+- 1/2).
+-
+- These constants come from the Unix98 standard and were also
+-available in 4.4BSD; therefore they are only defined if `_BSD_SOURCE' or
+-`_XOPEN_SOURCE=500', or a more general feature select macro, is
+-defined. The default set of features includes these constants. *Note
+-Feature Test Macros::.
+-
+- All values are of type `double'. As an extension, the GNU C library
+-also defines these constants with type `long double'. The `long
+-double' macros have a lowercase `l' appended to their names: `M_El',
+-`M_PIl', and so forth. These are only available if `_GNU_SOURCE' is
+-defined.
+-
+- _Note:_ Some programs use a constant named `PI' which has the same
+-value as `M_PI'. This constant is not standard; it may have appeared
+-in some old AT&T headers, and is mentioned in Stroustrup's book on C++.
+-It infringes on the user's name space, so the GNU C library does not
+-define it. Fixing programs written to expect it is simple: replace
+-`PI' with `M_PI' throughout, or put `-DPI=M_PI' on the compiler command
+-line.

+-Trigonometric Functions
+-=======================
+-
+- These are the familiar `sin', `cos', and `tan' functions. The
+-arguments to all of these functions are in units of radians; recall
+-that pi radians equals 180 degrees.
+-
+- The math library normally defines `M_PI' to a `double' approximation
+-of pi. If strict ISO and/or POSIX compliance are requested this
+-constant is not defined, but you can easily define it yourself:
+-
+- #define M_PI 3.14159265358979323846264338327
+-
+-You can also compute the value of pi with the expression `acos (-1.0)'.
+-
+- - Function: double sin (double X)
+- - Function: float sinf (float X)
+- - Function: long double sinl (long double X)
+- These functions return the sine of X, where X is given in radians.
+- The return value is in the range `-1' to `1'.
+-
+- - Function: double cos (double X)
+- - Function: float cosf (float X)
+- - Function: long double cosl (long double X)
+- These functions return the cosine of X, where X is given in
+- radians. The return value is in the range `-1' to `1'.
+-
+- - Function: double tan (double X)
+- - Function: float tanf (float X)
+- - Function: long double tanl (long double X)
+- These functions return the tangent of X, where X is given in
+- radians.
+-
+- Mathematically, the tangent function has singularities at odd
+- multiples of pi/2. If the argument X is too close to one of these
+- singularities, `tan' will signal overflow.
+-
+- In many applications where `sin' and `cos' are used, the sine and
+-cosine of the same angle are needed at the same time. It is more
+-efficient to compute them simultaneously, so the library provides a
+-function to do that.
+-
+- - Function: void sincos (double X, double *SINX, double *COSX)
+- - Function: void sincosf (float X, float *SINX, float *COSX)
+- - Function: void sincosl (long double X, long double *SINX, long
+- double *COSX)
+- These functions return the sine of X in `*SINX' and the cosine of
+- X in `*COS', where X is given in radians. Both values, `*SINX'
+- and `*COSX', are in the range of `-1' to `1'.
+-
+- This function is a GNU extension. Portable programs should be
+- prepared to cope with its absence.
+-
+- ISO C99 defines variants of the trig functions which work on complex
+-numbers. The GNU C library provides these functions, but they are only
+-useful if your compiler supports the new complex types defined by the
+-standard. (As of this writing GCC supports complex numbers, but there
+-are bugs in the implementation.)
+-
+- - Function: complex double csin (complex double Z)
+- - Function: complex float csinf (complex float Z)
+- - Function: complex long double csinl (complex long double Z)
+- These functions return the complex sine of Z. The mathematical
+- definition of the complex sine is
+-
+- sin (z) = 1/(2*i) * (exp (z*i) - exp (-z*i)).
+-
+- - Function: complex double ccos (complex double Z)
+- - Function: complex float ccosf (complex float Z)
+- - Function: complex long double ccosl (complex long double Z)
+- These functions return the complex cosine of Z. The mathematical
+- definition of the complex cosine is
+-
+- cos (z) = 1/2 * (exp (z*i) + exp (-z*i))
+-
+- - Function: complex double ctan (complex double Z)
+- - Function: complex float ctanf (complex float Z)
+- - Function: complex long double ctanl (complex long double Z)
+- These functions return the complex tangent of Z. The mathematical
+- definition of the complex tangent is
+-
+- tan (z) = -i * (exp (z*i) - exp (-z*i)) / (exp (z*i) + exp (-z*i))
+-
+- The complex tangent has poles at pi/2 + 2n, where n is an integer.
+- `ctan' may signal overflow if Z is too close to a pole.

+-
+-Inverse Trigonometric Functions
+-===============================
+-
+- These are the usual arc sine, arc cosine and arc tangent functions,
+-which are the inverses of the sine, cosine and tangent functions
+-respectively.
+-
+- - Function: double asin (double X)
+- - Function: float asinf (float X)
+- - Function: long double asinl (long double X)
+- These functions compute the arc sine of X--that is, the value whose
+- sine is X. The value is in units of radians. Mathematically,
+- there are infinitely many such values; the one actually returned
+- is the one between `-pi/2' and `pi/2' (inclusive).
+-
+- The arc sine function is defined mathematically only over the
+- domain `-1' to `1'. If X is outside the domain, `asin' signals a
+- domain error.
+-
+- - Function: double acos (double X)
+- - Function: float acosf (float X)
+- - Function: long double acosl (long double X)
+- These functions compute the arc cosine of X--that is, the value
+- whose cosine is X. The value is in units of radians.
+- Mathematically, there are infinitely many such values; the one
+- actually returned is the one between `0' and `pi' (inclusive).
+-
+- The arc cosine function is defined mathematically only over the
+- domain `-1' to `1'. If X is outside the domain, `acos' signals a
+- domain error.
+-
+- - Function: double atan (double X)
+- - Function: float atanf (float X)
+- - Function: long double atanl (long double X)
+- These functions compute the arc tangent of X--that is, the value
+- whose tangent is X. The value is in units of radians.
+- Mathematically, there are infinitely many such values; the one
+- actually returned is the one between `-pi/2' and `pi/2'
+- (inclusive).
+-
+- - Function: double atan2 (double Y, double X)
+- - Function: float atan2f (float Y, float X)
+- - Function: long double atan2l (long double Y, long double X)
+- This function computes the arc tangent of Y/X, but the signs of
+- both arguments are used to determine the quadrant of the result,
+- and X is permitted to be zero. The return value is given in
+- radians and is in the range `-pi' to `pi', inclusive.
+-
+- If X and Y are coordinates of a point in the plane, `atan2'
+- returns the signed angle between the line from the origin to that
+- point and the x-axis. Thus, `atan2' is useful for converting
+- Cartesian coordinates to polar coordinates. (To compute the
+- radial coordinate, use `hypot'; see *Note Exponents and
+- Logarithms::.)
+-
+- If both X and Y are zero, `atan2' returns zero.
+-
+- ISO C99 defines complex versions of the inverse trig functions.
+-
+- - Function: complex double casin (complex double Z)
+- - Function: complex float casinf (complex float Z)
+- - Function: complex long double casinl (complex long double Z)
+- These functions compute the complex arc sine of Z--that is, the
+- value whose sine is Z. The value returned is in radians.
+-
+- Unlike the real-valued functions, `casin' is defined for all
+- values of Z.
+-
+- - Function: complex double cacos (complex double Z)
+- - Function: complex float cacosf (complex float Z)
+- - Function: complex long double cacosl (complex long double Z)
+- These functions compute the complex arc cosine of Z--that is, the
+- value whose cosine is Z. The value returned is in radians.
+-
+- Unlike the real-valued functions, `cacos' is defined for all
+- values of Z.
+-
+- - Function: complex double catan (complex double Z)
+- - Function: complex float catanf (complex float Z)
+- - Function: complex long double catanl (complex long double Z)
+- These functions compute the complex arc tangent of Z--that is, the
+- value whose tangent is Z. The value is in units of radians.

+-Exponentiation and Logarithms
+-=============================
+-
+- - Function: double exp (double X)
+- - Function: float expf (float X)
+- - Function: long double expl (long double X)
+- These functions compute `e' (the base of natural logarithms) raised
+- to the power X.
+-
+- If the magnitude of the result is too large to be representable,
+- `exp' signals overflow.
+-
+- - Function: double exp2 (double X)
+- - Function: float exp2f (float X)
+- - Function: long double exp2l (long double X)
+- These functions compute `2' raised to the power X.
+- Mathematically, `exp2 (x)' is the same as `exp (x * log (2))'.
+-
+- - Function: double exp10 (double X)
+- - Function: float exp10f (float X)
+- - Function: long double exp10l (long double X)
+- - Function: double pow10 (double X)
+- - Function: float pow10f (float X)
+- - Function: long double pow10l (long double X)
+- These functions compute `10' raised to the power X.
+- Mathematically, `exp10 (x)' is the same as `exp (x * log (10))'.
+-
+- These functions are GNU extensions. The name `exp10' is
+- preferred, since it is analogous to `exp' and `exp2'.
+-
+- - Function: double log (double X)
+- - Function: float logf (float X)
+- - Function: long double logl (long double X)
+- These functions compute the natural logarithm of X. `exp (log
+- (X))' equals X, exactly in mathematics and approximately in C.
+-
+- If X is negative, `log' signals a domain error. If X is zero, it
+- returns negative infinity; if X is too close to zero, it may
+- signal overflow.
+-
+- - Function: double log10 (double X)
+- - Function: float log10f (float X)
+- - Function: long double log10l (long double X)
+- These functions return the base-10 logarithm of X. `log10 (X)'
+- equals `log (X) / log (10)'.
+-
+-
+- - Function: double log2 (double X)
+- - Function: float log2f (float X)
+- - Function: long double log2l (long double X)
+- These functions return the base-2 logarithm of X. `log2 (X)'
+- equals `log (X) / log (2)'.
+-
+- - Function: double logb (double X)
+- - Function: float logbf (float X)
+- - Function: long double logbl (long double X)
+- These functions extract the exponent of X and return it as a
+- floating-point value. If `FLT_RADIX' is two, `logb' is equal to
+- `floor (log2 (x))', except it's probably faster.
+-
+- If X is de-normalized, `logb' returns the exponent X would have if
+- it were normalized. If X is infinity (positive or negative),
+- `logb' returns oo. If X is zero, `logb' returns oo. It does not
+- signal.
+-
+- - Function: int ilogb (double X)
+- - Function: int ilogbf (float X)
+- - Function: int ilogbl (long double X)
+- These functions are equivalent to the corresponding `logb'
+- functions except that they return signed integer values.
+-
+-Since integers cannot represent infinity and NaN, `ilogb' instead
+-returns an integer that can't be the exponent of a normal floating-point
+-number. `math.h' defines constants so you can check for this.
+-
+- - Macro: int FP_ILOGB0
+- `ilogb' returns this value if its argument is `0'. The numeric
+- value is either `INT_MIN' or `-INT_MAX'.
+-
+- This macro is defined in ISO C99.
+-
+- - Macro: int FP_ILOGBNAN
+- `ilogb' returns this value if its argument is `NaN'. The numeric
+- value is either `INT_MIN' or `INT_MAX'.
+-
+- This macro is defined in ISO C99.
+-
+- These values are system specific. They might even be the same. The
+-proper way to test the result of `ilogb' is as follows:
+-
+- i = ilogb (f);
+- if (i == FP_ILOGB0 || i == FP_ILOGBNAN)
+- {
+- if (isnan (f))
+- {
+- /* Handle NaN. */
+- }
+- else if (f == 0.0)
+- {
+- /* Handle 0.0. */
+- }
+- else
+- {
+- /* Some other value with large exponent,
+- perhaps +Inf. */
+- }
+- }
+-
+- - Function: double pow (double BASE, double POWER)
+- - Function: float powf (float BASE, float POWER)
+- - Function: long double powl (long double BASE, long double POWER)
+- These are general exponentiation functions, returning BASE raised
+- to POWER.
+-
+- Mathematically, `pow' would return a complex number when BASE is
+- negative and POWER is not an integral value. `pow' can't do that,
+- so instead it signals a domain error. `pow' may also underflow or
+- overflow the destination type.
+-
+- - Function: double sqrt (double X)
+- - Function: float sqrtf (float X)
+- - Function: long double sqrtl (long double X)
+- These functions return the nonnegative square root of X.
+-
+- If X is negative, `sqrt' signals a domain error. Mathematically,
+- it should return a complex number.
+-
+- - Function: double cbrt (double X)
+- - Function: float cbrtf (float X)
+- - Function: long double cbrtl (long double X)
+- These functions return the cube root of X. They cannot fail;
+- every representable real value has a representable real cube root.
+-
+- - Function: double hypot (double X, double Y)
+- - Function: float hypotf (float X, float Y)
+- - Function: long double hypotl (long double X, long double Y)
+- These functions return `sqrt (X*X + Y*Y)'. This is the length of
+- the hypotenuse of a right triangle with sides of length X and Y,
+- or the distance of the point (X, Y) from the origin. Using this
+- function instead of the direct formula is wise, since the error is
+- much smaller. See also the function `cabs' in *Note Absolute
+- Value::.
+-
+- - Function: double expm1 (double X)
+- - Function: float expm1f (float X)
+- - Function: long double expm1l (long double X)
+- These functions return a value equivalent to `exp (X) - 1'. They
+- are computed in a way that is accurate even if X is near zero--a
+- case where `exp (X) - 1' would be inaccurate owing to subtraction
+- of two numbers that are nearly equal.
+-
+- - Function: double log1p (double X)
+- - Function: float log1pf (float X)
+- - Function: long double log1pl (long double X)
+- These functions returns a value equivalent to `log (1 + X)'. They
+- are computed in a way that is accurate even if X is near zero.
+-
+- ISO C99 defines complex variants of some of the exponentiation and
+-logarithm functions.
+-
+- - Function: complex double cexp (complex double Z)
+- - Function: complex float cexpf (complex float Z)
+- - Function: complex long double cexpl (complex long double Z)
+- These functions return `e' (the base of natural logarithms) raised
+- to the power of Z. Mathematically, this corresponds to the value
+-
+- exp (z) = exp (creal (z)) * (cos (cimag (z)) + I * sin (cimag (z)))
+-
+- - Function: complex double clog (complex double Z)
+- - Function: complex float clogf (complex float Z)
+- - Function: complex long double clogl (complex long double Z)
+- These functions return the natural logarithm of Z.
+- Mathematically, this corresponds to the value
+-
+- log (z) = log (cabs (z)) + I * carg (z)
+-
+- `clog' has a pole at 0, and will signal overflow if Z equals or is
+- very close to 0. It is well-defined for all other values of Z.
+-
+- - Function: complex double clog10 (complex double Z)
+- - Function: complex float clog10f (complex float Z)
+- - Function: complex long double clog10l (complex long double Z)
+- These functions return the base 10 logarithm of the complex value
+- Z. Mathematically, this corresponds to the value
+-
+- log (z) = log10 (cabs (z)) + I * carg (z)
+-
+- These functions are GNU extensions.
+-
+- - Function: complex double csqrt (complex double Z)
+- - Function: complex float csqrtf (complex float Z)
+- - Function: complex long double csqrtl (complex long double Z)
+- These functions return the complex square root of the argument Z.
+- Unlike the real-valued functions, they are defined for all values
+- of Z.
+-
+- - Function: complex double cpow (complex double BASE, complex double
+- POWER)
+- - Function: complex float cpowf (complex float BASE, complex float
+- POWER)
+- - Function: complex long double cpowl (complex long double BASE,
+- complex long double POWER)
+- These functions return BASE raised to the power of POWER. This is
+- equivalent to `cexp (y * clog (x))'

+-Special Functions
+-=================
+-
+- These are some more exotic mathematical functions which are sometimes
+-useful. Currently they only have real-valued versions.
+-
+- - Function: double erf (double X)
+- - Function: float erff (float X)
+- - Function: long double erfl (long double X)
+- `erf' returns the error function of X. The error function is
+- defined as
+- erf (x) = 2/sqrt(pi) * integral from 0 to x of exp(-t^2) dt
+-
+- - Function: double erfc (double X)
+- - Function: float erfcf (float X)
+- - Function: long double erfcl (long double X)
+- `erfc' returns `1.0 - erf(X)', but computed in a fashion that
+- avoids round-off error when X is large.
+-
+- - Function: double lgamma (double X)
+- - Function: float lgammaf (float X)
+- - Function: long double lgammal (long double X)
+- `lgamma' returns the natural logarithm of the absolute value of
+- the gamma function of X. The gamma function is defined as
+- gamma (x) = integral from 0 to oo of t^(x-1) e^-t dt
+-
+- The sign of the gamma function is stored in the global variable
+- SIGNGAM, which is declared in `math.h'. It is `1' if the
+- intermediate result was positive or zero, or `-1' if it was
+- negative.
+-
+- To compute the real gamma function you can use the `tgamma'
+- function or you can compute the values as follows:
+- lgam = lgamma(x);
+- gam = signgam*exp(lgam);
+-
+- The gamma function has singularities at the non-positive integers.
+- `lgamma' will raise the zero divide exception if evaluated at a
+- singularity.
+-
+- - Function: double lgamma_r (double X, int *SIGNP)
+- - Function: float lgammaf_r (float X, int *SIGNP)
+- - Function: long double lgammal_r (long double X, int *SIGNP)
+- `lgamma_r' is just like `lgamma', but it stores the sign of the
+- intermediate result in the variable pointed to by SIGNP instead of
+- in the SIGNGAM global. This means it is reentrant.
+-
+- - Function: double gamma (double X)
+- - Function: float gammaf (float X)
+- - Function: long double gammal (long double X)
+- These functions exist for compatibility reasons. They are
+- equivalent to `lgamma' etc. It is better to use `lgamma' since
+- for one the name reflects better the actual computation, moreover
+- `lgamma' is standardized in ISO C99 while `gamma' is not.
+-
+- - Function: double tgamma (double X)
+- - Function: float tgammaf (float X)
+- - Function: long double tgammal (long double X)
+- `tgamma' applies the gamma function to X. The gamma function is
+- defined as
+- gamma (x) = integral from 0 to oo of t^(x-1) e^-t dt
+-
+- This function was introduced in ISO C99.
+-
+- - Function: double j0 (double X)
+- - Function: float j0f (float X)
+- - Function: long double j0l (long double X)
+- `j0' returns the Bessel function of the first kind of order 0 of
+- X. It may signal underflow if X is too large.
+-
+- - Function: double j1 (double X)
+- - Function: float j1f (float X)
+- - Function: long double j1l (long double X)
+- `j1' returns the Bessel function of the first kind of order 1 of
+- X. It may signal underflow if X is too large.
+-
+- - Function: double jn (int n, double X)
+- - Function: float jnf (int n, float X)
+- - Function: long double jnl (int n, long double X)
+- `jn' returns the Bessel function of the first kind of order N of
+- X. It may signal underflow if X is too large.
+-
+- - Function: double y0 (double X)
+- - Function: float y0f (float X)
+- - Function: long double y0l (long double X)
+- `y0' returns the Bessel function of the second kind of order 0 of
+- X. It may signal underflow if X is too large. If X is negative,
+- `y0' signals a domain error; if it is zero, `y0' signals overflow
+- and returns -oo.
+-
+- - Function: double y1 (double X)
+- - Function: float y1f (float X)
+- - Function: long double y1l (long double X)
+- `y1' returns the Bessel function of the second kind of order 1 of
+- X. It may signal underflow if X is too large. If X is negative,
+- `y1' signals a domain error; if it is zero, `y1' signals overflow
+- and returns -oo.
+-
+- - Function: double yn (int n, double X)
+- - Function: float ynf (int n, float X)
+- - Function: long double ynl (int n, long double X)
+- `yn' returns the Bessel function of the second kind of order N of
+- X. It may signal underflow if X is too large. If X is negative,
+- `yn' signals a domain error; if it is zero, `yn' signals overflow
+- and returns -oo.

+-Known Maximum Errors in Math Functions
+-======================================
+-
+- This section lists the known errors of the functions in the math
+-library. Errors are measured in "units of the last place". This is a
+-measure for the relative error. For a number z with the representation
+-d.d...d*2^e (we assume IEEE floating-point numbers with base 2) the ULP
+-is represented by
+-
+- |d.d...d - (z / 2^e)| / 2^(p - 1)
+-
+-where p is the number of bits in the mantissa of the floating-point
+-number representation. Ideally the error for all functions is always
+-less than 0.5ulps. Using rounding bits this is also possible and
+-normally implemented for the basic operations. To achieve the same for
+-the complex math functions requires a lot more work and this has not
+-yet been done.
+-
+- Therefore many of the functions in the math library have errors. The
+-table lists the maximum error for each function which is exposed by one
+-of the existing tests in the test suite. The table tries to cover as
+-much as possible and list the actual maximum error (or at least a
+-ballpark figure) but this is often not achieved due to the large search
+-space.
+-
+- The table lists the ULP values for different architectures.
+-Different architectures have different results since their hardware
+-support for floating-point operations varies and also the existing
+-hardware support is different.

+-Pseudo-Random Numbers
+-=====================
+-
+- This section describes the GNU facilities for generating a series of
+-pseudo-random numbers. The numbers generated are not truly random;
+-typically, they form a sequence that repeats periodically, with a period
+-so large that you can ignore it for ordinary purposes. The random
+-number generator works by remembering a "seed" value which it uses to
+-compute the next random number and also to compute a new seed.
+-
+- Although the generated numbers look unpredictable within one run of a
+-program, the sequence of numbers is _exactly the same_ from one run to
+-the next. This is because the initial seed is always the same. This
+-is convenient when you are debugging a program, but it is unhelpful if
+-you want the program to behave unpredictably. If you want a different
+-pseudo-random series each time your program runs, you must specify a
+-different seed each time. For ordinary purposes, basing the seed on the
+-current time works well.
+-
+- You can obtain repeatable sequences of numbers on a particular
+-machine type by specifying the same initial seed value for the random
+-number generator. There is no standard meaning for a particular seed
+-value; the same seed, used in different C libraries or on different CPU
+-types, will give you different random numbers.
+-
+- The GNU library supports the standard ISO C random number functions
+-plus two other sets derived from BSD and SVID. The BSD and ISO C
+-functions provide identical, somewhat limited functionality. If only a
+-small number of random bits are required, we recommend you use the
+-ISO C interface, `rand' and `srand'. The SVID functions provide a more
+-flexible interface, which allows better random number generator
+-algorithms, provides more random bits (up to 48) per call, and can
+-provide random floating-point numbers. These functions are required by
+-the XPG standard and therefore will be present in all modern Unix
+-systems.

+-
+-ISO C Random Number Functions
+------------------------------
+-
+- This section describes the random number functions that are part of
+-the ISO C standard.
+-
+- To use these facilities, you should include the header file
+-`stdlib.h' in your program.
+-
+- - Macro: int RAND_MAX
+- The value of this macro is an integer constant representing the
+- largest value the `rand' function can return. In the GNU library,
+- it is `2147483647', which is the largest signed integer
+- representable in 32 bits. In other libraries, it may be as low as
+- `32767'.
+-
+- - Function: int rand (void)
+- The `rand' function returns the next pseudo-random number in the
+- series. The value ranges from `0' to `RAND_MAX'.
+-
+- - Function: void srand (unsigned int SEED)
+- This function establishes SEED as the seed for a new series of
+- pseudo-random numbers. If you call `rand' before a seed has been
+- established with `srand', it uses the value `1' as a default seed.
+-
+- To produce a different pseudo-random series each time your program
+- is run, do `srand (time (0))'.
+-
+- POSIX.1 extended the C standard functions to support reproducible
+-random numbers in multi-threaded programs. However, the extension is
+-badly designed and unsuitable for serious work.
+-
+- - Function: int rand_r (unsigned int *SEED)
+- This function returns a random number in the range 0 to `RAND_MAX'
+- just as `rand' does. However, all its state is stored in the SEED
+- argument. This means the RNG's state can only have as many bits
+- as the type `unsigned int' has. This is far too few to provide a
+- good RNG.
+-
+- If your program requires a reentrant RNG, we recommend you use the
+- reentrant GNU extensions to the SVID random number generator. The
+- POSIX.1 interface should only be used when the GNU extensions are
+- not available.

+-
+-BSD Random Number Functions
+----------------------------
+-
+- This section describes a set of random number generation functions
+-that are derived from BSD. There is no advantage to using these
+-functions with the GNU C library; we support them for BSD compatibility
+-only.
+-
+- The prototypes for these functions are in `stdlib.h'.
+-
+- - Function: long int random (void)
+- This function returns the next pseudo-random number in the
+- sequence. The value returned ranges from `0' to `RAND_MAX'.
+-
+- *Note:* Temporarily this function was defined to return a
+- `int32_t' value to indicate that the return value always contains
+- 32 bits even if `long int' is wider. The standard demands it
+- differently. Users must always be aware of the 32-bit limitation,
+- though.
+-
+- - Function: void srandom (unsigned int SEED)
+- The `srandom' function sets the state of the random number
+- generator based on the integer SEED. If you supply a SEED value
+- of `1', this will cause `random' to reproduce the default set of
+- random numbers.
+-
+- To produce a different set of pseudo-random numbers each time your
+- program runs, do `srandom (time (0))'.
+-
+- - Function: void * initstate (unsigned int SEED, void *STATE, size_t
+- SIZE)
+- The `initstate' function is used to initialize the random number
+- generator state. The argument STATE is an array of SIZE bytes,
+- used to hold the state information. It is initialized based on
+- SEED. The size must be between 8 and 256 bytes, and should be a
+- power of two. The bigger the STATE array, the better.
+-
+- The return value is the previous value of the state information
+- array. You can use this value later as an argument to `setstate'
+- to restore that state.
+-
+- - Function: void * setstate (void *STATE)
+- The `setstate' function restores the random number state
+- information STATE. The argument must have been the result of a
+- previous call to INITSTATE or SETSTATE.
+-
+- The return value is the previous value of the state information
+- array. You can use this value later as an argument to `setstate'
+- to restore that state.
+-
+- If the function fails the return value is `NULL'.
+-
+- The four functions described so far in this section all work on a
+-state which is shared by all threads. The state is not directly
+-accessible to the user and can only be modified by these functions.
+-This makes it hard to deal with situations where each thread should
+-have its own pseudo-random number generator.
+-
+- The GNU C library contains four additional functions which contain
+-the state as an explicit parameter and therefore make it possible to
+-handle thread-local PRNGs. Beside this there are no difference. In
+-fact, the four functions already discussed are implemented internally
+-using the following interfaces.
+-
+- The `stdlib.h' header contains a definition of the following type:
+-
+- - Data Type: struct random_data
+- Objects of type `struct random_data' contain the information
+- necessary to represent the state of the PRNG. Although a complete
+- definition of the type is present the type should be treated as
+- opaque.
+-
+- The functions modifying the state follow exactly the already
+-described functions.
+-
+- - Function: int random_r (struct random_data *restrict BUF, int32_t
+- *restrict RESULT)
+- The `random_r' function behaves exactly like the `random' function
+- except that it uses and modifies the state in the object pointed
+- to by the first parameter instead of the global state.
+-
+- - Function: int srandom_r (unsigned int SEED, struct random_data *BUF)
+- The `srandom_r' function behaves exactly like the `srandom'
+- function except that it uses and modifies the state in the object
+- pointed to by the second parameter instead of the global state.
+-
+- - Function: int initstate_r (unsigned int SEED, char *restrict
+- STATEBUF, size_t STATELEN, struct random_data *restrict BUF)
+- The `initstate_r' function behaves exactly like the `initstate'
+- function except that it uses and modifies the state in the object
+- pointed to by the fourth parameter instead of the global state.
+-
+- - Function: int setstate_r (char *restrict STATEBUF, struct
+- random_data *restrict BUF)
+- The `setstate_r' function behaves exactly like the `setstate'
+- function except that it uses and modifies the state in the object
+- pointed to by the first parameter instead of the global state.

+-SVID Random Number Function
+----------------------------
+-
+- The C library on SVID systems contains yet another kind of random
+-number generator functions. They use a state of 48 bits of data. The
+-user can choose among a collection of functions which return the random
+-bits in different forms.
+-
+- Generally there are two kinds of function. The first uses a state of
+-the random number generator which is shared among several functions and
+-by all threads of the process. The second requires the user to handle
+-the state.
+-
+- All functions have in common that they use the same congruential
+-formula with the same constants. The formula is
+-
+- Y = (a * X + c) mod m
+-
+-where X is the state of the generator at the beginning and Y the state
+-at the end. `a' and `c' are constants determining the way the
+-generator works. By default they are
+-
+- a = 0x5DEECE66D = 25214903917
+- c = 0xb = 11
+-
+-but they can also be changed by the user. `m' is of course 2^48 since
+-the state consists of a 48-bit array.
+-
+- The prototypes for these functions are in `stdlib.h'.
+-
+- - Function: double drand48 (void)
+- This function returns a `double' value in the range of `0.0' to
+- `1.0' (exclusive). The random bits are determined by the global
+- state of the random number generator in the C library.
+-
+- Since the `double' type according to IEEE 754 has a 52-bit
+- mantissa this means 4 bits are not initialized by the random number
+- generator. These are (of course) chosen to be the least
+- significant bits and they are initialized to `0'.
+-
+- - Function: double erand48 (unsigned short int XSUBI[3])
+- This function returns a `double' value in the range of `0.0' to
+- `1.0' (exclusive), similarly to `drand48'. The argument is an
+- array describing the state of the random number generator.
+-
+- This function can be called subsequently since it updates the
+- array to guarantee random numbers. The array should have been
+- initialized before initial use to obtain reproducible results.
+-
+- - Function: long int lrand48 (void)
+- The `lrand48' function returns an integer value in the range of
+- `0' to `2^31' (exclusive). Even if the size of the `long int'
+- type can take more than 32 bits, no higher numbers are returned.
+- The random bits are determined by the global state of the random
+- number generator in the C library.
+-
+- - Function: long int nrand48 (unsigned short int XSUBI[3])
+- This function is similar to the `lrand48' function in that it
+- returns a number in the range of `0' to `2^31' (exclusive) but the
+- state of the random number generator used to produce the random
+- bits is determined by the array provided as the parameter to the
+- function.
+-
+- The numbers in the array are updated afterwards so that subsequent
+- calls to this function yield different results (as is expected of
+- a random number generator). The array should have been
+- initialized before the first call to obtain reproducible results.
+-
+- - Function: long int mrand48 (void)
+- The `mrand48' function is similar to `lrand48'. The only
+- difference is that the numbers returned are in the range `-2^31' to
+- `2^31' (exclusive).
+-
+- - Function: long int jrand48 (unsigned short int XSUBI[3])
+- The `jrand48' function is similar to `nrand48'. The only
+- difference is that the numbers returned are in the range `-2^31' to
+- `2^31' (exclusive). For the `xsubi' parameter the same
+- requirements are necessary.
+-
+- The internal state of the random number generator can be initialized
+-in several ways. The methods differ in the completeness of the
+-information provided.
+-
+- - Function: void srand48 (long int SEEDVAL)
+- The `srand48' function sets the most significant 32 bits of the
+- internal state of the random number generator to the least
+- significant 32 bits of the SEEDVAL parameter. The lower 16 bits
+- are initialized to the value `0x330E'. Even if the `long int'
+- type contains more than 32 bits only the lower 32 bits are used.
+-
+- Owing to this limitation, initialization of the state of this
+- function is not very useful. But it makes it easy to use a
+- construct like `srand48 (time (0))'.
+-
+- A side-effect of this function is that the values `a' and `c' from
+- the internal state, which are used in the congruential formula,
+- are reset to the default values given above. This is of
+- importance once the user has called the `lcong48' function (see
+- below).
+-
+- - Function: unsigned short int * seed48 (unsigned short int SEED16V[3])
+- The `seed48' function initializes all 48 bits of the state of the
+- internal random number generator from the contents of the parameter
+- SEED16V. Here the lower 16 bits of the first element of SEE16V
+- initialize the least significant 16 bits of the internal state,
+- the lower 16 bits of `SEED16V[1]' initialize the mid-order 16 bits
+- of the state and the 16 lower bits of `SEED16V[2]' initialize the
+- most significant 16 bits of the state.
+-
+- Unlike `srand48' this function lets the user initialize all 48 bits
+- of the state.
+-
+- The value returned by `seed48' is a pointer to an array containing
+- the values of the internal state before the change. This might be
+- useful to restart the random number generator at a certain state.
+- Otherwise the value can simply be ignored.
+-
+- As for `srand48', the values `a' and `c' from the congruential
+- formula are reset to the default values.
+-
+- There is one more function to initialize the random number generator
+-which enables you to specify even more information by allowing you to
+-change the parameters in the congruential formula.
+-
+- - Function: void lcong48 (unsigned short int PARAM[7])
+- The `lcong48' function allows the user to change the complete state
+- of the random number generator. Unlike `srand48' and `seed48',
+- this function also changes the constants in the congruential
+- formula.
+-
+- From the seven elements in the array PARAM the least significant
+- 16 bits of the entries `PARAM[0]' to `PARAM[2]' determine the
+- initial state, the least significant 16 bits of `PARAM[3]' to
+- `PARAM[5]' determine the 48 bit constant `a' and `PARAM[6]'
+- determines the 16-bit value `c'.
+-
+- All the above functions have in common that they use the global
+-parameters for the congruential formula. In multi-threaded programs it
+-might sometimes be useful to have different parameters in different
+-threads. For this reason all the above functions have a counterpart
+-which works on a description of the random number generator in the
+-user-supplied buffer instead of the global state.
+-
+- Please note that it is no problem if several threads use the global
+-state if all threads use the functions which take a pointer to an array
+-containing the state. The random numbers are computed following the
+-same loop but if the state in the array is different all threads will
+-obtain an individual random number generator.
+-
+- The user-supplied buffer must be of type `struct drand48_data'.
+-This type should be regarded as opaque and not manipulated directly.
+-
+- - Function: int drand48_r (struct drand48_data *BUFFER, double *RESULT)
+- This function is equivalent to the `drand48' function with the
+- difference that it does not modify the global random number
+- generator parameters but instead the parameters in the buffer
+- supplied through the pointer BUFFER. The random number is
+- returned in the variable pointed to by RESULT.
+-
+- The return value of the function indicates whether the call
+- succeeded. If the value is less than `0' an error occurred and
+- ERRNO is set to indicate the problem.
+-
+- This function is a GNU extension and should not be used in portable
+- programs.
+-
+- - Function: int erand48_r (unsigned short int XSUBI[3], struct
+- drand48_data *BUFFER, double *RESULT)
+- The `erand48_r' function works like `erand48', but in addition it
+- takes an argument BUFFER which describes the random number
+- generator. The state of the random number generator is taken from
+- the `xsubi' array, the parameters for the congruential formula
+- from the global random number generator data. The random number
+- is returned in the variable pointed to by RESULT.
+-
+- The return value is non-negative if the call succeeded.
+-
+- This function is a GNU extension and should not be used in portable
+- programs.
+-
+- - Function: int lrand48_r (struct drand48_data *BUFFER, double *RESULT)
+- This function is similar to `lrand48', but in addition it takes a
+- pointer to a buffer describing the state of the random number
+- generator just like `drand48'.
+-
+- If the return value of the function is non-negative the variable
+- pointed to by RESULT contains the result. Otherwise an error
+- occurred.
+-
+- This function is a GNU extension and should not be used in portable
+- programs.
+-
+- - Function: int nrand48_r (unsigned short int XSUBI[3], struct
+- drand48_data *BUFFER, long int *RESULT)
+- The `nrand48_r' function works like `nrand48' in that it produces
+- a random number in the range `0' to `2^31'. But instead of using
+- the global parameters for the congruential formula it uses the
+- information from the buffer pointed to by BUFFER. The state is
+- described by the values in XSUBI.
+-
+- If the return value is non-negative the variable pointed to by
+- RESULT contains the result.
+-
+- This function is a GNU extension and should not be used in portable
+- programs.
+-
+- - Function: int mrand48_r (struct drand48_data *BUFFER, double *RESULT)
+- This function is similar to `mrand48' but like the other reentrant
+- functions it uses the random number generator described by the
+- value in the buffer pointed to by BUFFER.
+-
+- If the return value is non-negative the variable pointed to by
+- RESULT contains the result.
+-
+- This function is a GNU extension and should not be used in portable
+- programs.
+-
+- - Function: int jrand48_r (unsigned short int XSUBI[3], struct
+- drand48_data *BUFFER, long int *RESULT)
+- The `jrand48_r' function is similar to `jrand48'. Like the other
+- reentrant functions of this function family it uses the
+- congruential formula parameters from the buffer pointed to by
+- BUFFER.
+-
+- If the return value is non-negative the variable pointed to by
+- RESULT contains the result.
+-
+- This function is a GNU extension and should not be used in portable
+- programs.
+-
+- Before any of the above functions are used the buffer of type
+-`struct drand48_data' should be initialized. The easiest way to do
+-this is to fill the whole buffer with null bytes, e.g. by
+-
+- memset (buffer, '\0', sizeof (struct drand48_data));
+-
+-Using any of the reentrant functions of this family now will
+-automatically initialize the random number generator to the default
+-values for the state and the parameters of the congruential formula.
+-
+- The other possibility is to use any of the functions which explicitly
+-initialize the buffer. Though it might be obvious how to initialize the
+-buffer from looking at the parameter to the function, it is highly
+-recommended to use these functions since the result might not always be
+-what you expect.
+-
+- - Function: int srand48_r (long int SEEDVAL, struct drand48_data
+- *BUFFER)
+- The description of the random number generator represented by the
+- information in BUFFER is initialized similarly to what the function
+- `srand48' does. The state is initialized from the parameter
+- SEEDVAL and the parameters for the congruential formula are
+- initialized to their default values.
+-
+- If the return value is non-negative the function call succeeded.
+-
+- This function is a GNU extension and should not be used in portable
+- programs.
+-
+- - Function: int seed48_r (unsigned short int SEED16V[3], struct
+- drand48_data *BUFFER)
+- This function is similar to `srand48_r' but like `seed48' it
+- initializes all 48 bits of the state from the parameter SEED16V.
+-
+- If the return value is non-negative the function call succeeded.
+- It does not return a pointer to the previous state of the random
+- number generator like the `seed48' function does. If the user
+- wants to preserve the state for a later re-run s/he can copy the
+- whole buffer pointed to by BUFFER.
+-
+- This function is a GNU extension and should not be used in portable
+- programs.
+-
+- - Function: int lcong48_r (unsigned short int PARAM[7], struct
+- drand48_data *BUFFER)
+- This function initializes all aspects of the random number
+- generator described in BUFFER with the data in PARAM. Here it is
+- especially true that the function does more than just copying the
+- contents of PARAM and BUFFER. More work is required and therefore
+- it is important to use this function rather than initializing the
+- random number generator directly.
+-
+- If the return value is non-negative the function call succeeded.
+-
+- This function is a GNU extension and should not be used in portable
+- programs.

+-
+-Is Fast Code or Small Code preferred?
+-=====================================
+-
+- If an application uses many floating point functions it is often the
+-case that the cost of the function calls themselves is not negligible.
+-Modern processors can often execute the operations themselves very
+-fast, but the function call disrupts the instruction pipeline.
+-
+- For this reason the GNU C Library provides optimizations for many of
+-the frequently-used math functions. When GNU CC is used and the user
+-activates the optimizer, several new inline functions and macros are
+-defined. These new functions and macros have the same names as the
+-library functions and so are used instead of the latter. In the case of
+-inline functions the compiler will decide whether it is reasonable to
+-use them, and this decision is usually correct.
+-
+- This means that no calls to the library functions may be necessary,
+-and can increase the speed of generated code significantly. The
+-drawback is that code size will increase, and the increase is not
+-always negligible.
+-
+- There are two kind of inline functions: Those that give the same
+-result as the library functions and others that might not set `errno'
+-and might have a reduced precision and/or argument range in comparison
+-with the library functions. The latter inline functions are only
+-available if the flag `-ffast-math' is given to GNU CC.
+-
+- In cases where the inline functions and macros are not wanted the
+-symbol `__NO_MATH_INLINES' should be defined before any system header is
+-included. This will ensure that only library functions are used. Of
+-course, it can be determined for each file in the project whether
+-giving this option is preferable or not.
+-
+- Not all hardware implements the entire IEEE 754 standard, and even
+-if it does there may be a substantial performance penalty for using some
+-of its features. For example, enabling traps on some processors forces
+-the FPU to run un-pipelined, which can more than double calculation
+-time.

+-Integers
+-========
+-
+- The C language defines several integer data types: integer, short
+-integer, long integer, and character, all in both signed and unsigned
+-varieties. The GNU C compiler extends the language to contain long
+-long integers as well.
+-
+- The C integer types were intended to allow code to be portable among
+-machines with different inherent data sizes (word sizes), so each type
+-may have different ranges on different machines. The problem with this
+-is that a program often needs to be written for a particular range of
+-integers, and sometimes must be written for a particular size of
+-storage, regardless of what machine the program runs on.
+-
+- To address this problem, the GNU C library contains C type
+-definitions you can use to declare integers that meet your exact needs.
+-Because the GNU C library header files are customized to a specific
+-machine, your program source code doesn't have to be.
+-
+- These `typedef's are in `stdint.h'.
+-
+- If you require that an integer be represented in exactly N bits, use
+-one of the following types, with the obvious mapping to bit size and
+-signedness:
+-
+- * int8_t
+-
+- * int16_t
+-
+- * int32_t
+-
+- * int64_t
+-
+- * uint8_t
+-
+- * uint16_t
+-
+- * uint32_t
+-
+- * uint64_t
+-
+- If your C compiler and target machine do not allow integers of a
+-certain size, the corresponding above type does not exist.
+-
+- If you don't need a specific storage size, but want the smallest data
+-structure with _at least_ N bits, use one of these:
+-
+- * int_least8_t
+-
+- * int_least16_t
+-
+- * int_least32_t
+-
+- * int_least64_t
+-
+- * uint_least8_t
+-
+- * uint_least16_t
+-
+- * uint_least32_t
+-
+- * uint_least64_t
+-
+- If you don't need a specific storage size, but want the data
+-structure that allows the fastest access while having at least N bits
+-(and among data structures with the same access speed, the smallest
+-one), use one of these:
+-
+- * int_fast8_t
+-
+- * int_fast16_t
+-
+- * int_fast32_t
+-
+- * int_fast64_t
+-
+- * uint_fast8_t
+-
+- * uint_fast16_t
+-
+- * uint_fast32_t
+-
+- * uint_fast64_t
+-
+- If you want an integer with the widest range possible on the
+-platform on which it is being used, use one of the following. If you
+-use these, you should write code that takes into account the variable
+-size and range of the integer.
+-
+- * intmax_t
+-
+- * uintmax_t
+-
+- The GNU C library also provides macros that tell you the maximum and
+-minimum possible values for each integer data type. The macro names
+-follow these examples: `INT32_MAX', `UINT8_MAX', `INT_FAST32_MIN',
+-`INT_LEAST64_MIN', `UINTMAX_MAX', `INTMAX_MAX', `INTMAX_MIN'. Note
+-that there are no macros for unsigned integer minima. These are always
+-zero.
+-
+- There are similar macros for use with C's built in integer types
+-which should come with your C compiler. These are described in *Note
+-Data Type Measurements::.
+-
+- Don't forget you can use the C `sizeof' function with any of these
+-data types to get the number of bytes of storage each uses.

+-Integer Division
+-================
+-
+- This section describes functions for performing integer division.
+-These functions are redundant when GNU CC is used, because in GNU C the
+-`/' operator always rounds towards zero. But in other C
+-implementations, `/' may round differently with negative arguments.
+-`div' and `ldiv' are useful because they specify how to round the
+-quotient: towards zero. The remainder has the same sign as the
+-numerator.
+-
+- These functions are specified to return a result R such that the
+-value `R.quot*DENOMINATOR + R.rem' equals NUMERATOR.
+-
+- To use these facilities, you should include the header file
+-`stdlib.h' in your program.
+-
+- - Data Type: div_t
+- This is a structure type used to hold the result returned by the
+- `div' function. It has the following members:
+-
+- `int quot'
+- The quotient from the division.
+-
+- `int rem'
+- The remainder from the division.
+-
+- - Function: div_t div (int NUMERATOR, int DENOMINATOR)
+- This function `div' computes the quotient and remainder from the
+- division of NUMERATOR by DENOMINATOR, returning the result in a
+- structure of type `div_t'.
+-
+- If the result cannot be represented (as in a division by zero), the
+- behavior is undefined.
+-
+- Here is an example, albeit not a very useful one.
+-
+- div_t result;
+- result = div (20, -6);
+-
+- Now `result.quot' is `-3' and `result.rem' is `2'.
+-
+- - Data Type: ldiv_t
+- This is a structure type used to hold the result returned by the
+- `ldiv' function. It has the following members:
+-
+- `long int quot'
+- The quotient from the division.
+-
+- `long int rem'
+- The remainder from the division.
+-
+- (This is identical to `div_t' except that the components are of
+- type `long int' rather than `int'.)
+-
+- - Function: ldiv_t ldiv (long int NUMERATOR, long int DENOMINATOR)
+- The `ldiv' function is similar to `div', except that the arguments
+- are of type `long int' and the result is returned as a structure
+- of type `ldiv_t'.
+-
+- - Data Type: lldiv_t
+- This is a structure type used to hold the result returned by the
+- `lldiv' function. It has the following members:
+-
+- `long long int quot'
+- The quotient from the division.
+-
+- `long long int rem'
+- The remainder from the division.
+-
+- (This is identical to `div_t' except that the components are of
+- type `long long int' rather than `int'.)
+-
+- - Function: lldiv_t lldiv (long long int NUMERATOR, long long int
+- DENOMINATOR)
+- The `lldiv' function is like the `div' function, but the arguments
+- are of type `long long int' and the result is returned as a
+- structure of type `lldiv_t'.
+-
+- The `lldiv' function was added in ISO C99.
+-
+- - Data Type: imaxdiv_t
+- This is a structure type used to hold the result returned by the
+- `imaxdiv' function. It has the following members:
+-
+- `intmax_t quot'
+- The quotient from the division.
+-
+- `intmax_t rem'
+- The remainder from the division.
+-
+- (This is identical to `div_t' except that the components are of
+- type `intmax_t' rather than `int'.)
+-
+- See *Note Integers:: for a description of the `intmax_t' type.
+-
+-
+- - Function: imaxdiv_t imaxdiv (intmax_t NUMERATOR, intmax_t
+- DENOMINATOR)
+- The `imaxdiv' function is like the `div' function, but the
+- arguments are of type `intmax_t' and the result is returned as a
+- structure of type `imaxdiv_t'.
+-
+- See *Note Integers:: for a description of the `intmax_t' type.

+-Floating Point Numbers
+-======================
+-
+- Most computer hardware has support for two different kinds of
+-numbers: integers (...-3, -2, -1, 0, 1, 2, 3...) and floating-point
+-numbers. Floating-point numbers have three parts: the "mantissa", the
+-"exponent", and the "sign bit". The real number represented by a
+-floating-point value is given by (s ? -1 : 1) * 2^e * M where s is the
+-sign bit, e the exponent, and M the mantissa. *Note Floating Point
+-Concepts::, for details. (It is possible to have a different "base"
+-for the exponent, but all modern hardware uses 2.)
+-
+- Floating-point numbers can represent a finite subset of the real
+-numbers. While this subset is large enough for most purposes, it is
+-important to remember that the only reals that can be represented
+-exactly are rational numbers that have a terminating binary expansion
+-shorter than the width of the mantissa. Even simple fractions such as
+-1/5 can only be approximated by floating point.
+-
+- Mathematical operations and functions frequently need to produce
+-values that are not representable. Often these values can be
+-approximated closely enough for practical purposes, but sometimes they
+-can't. Historically there was no way to tell when the results of a
+-calculation were inaccurate. Modern computers implement the IEEE 754
+-standard for numerical computations, which defines a framework for
+-indicating to the program when the results of calculation are not
+-trustworthy. This framework consists of a set of "exceptions" that
+-indicate why a result could not be represented, and the special values
+-"infinity" and "not a number" (NaN).

+-Floating-Point Number Classification Functions
+-==============================================
+-
+- ISO C99 defines macros that let you determine what sort of
+-floating-point number a variable holds.
+-
+- - Macro: int fpclassify (_float-type_ X)
+- This is a generic macro which works on all floating-point types and
+- which returns a value of type `int'. The possible values are:
+-
+- `FP_NAN'
+- The floating-point number X is "Not a Number" (*note Infinity
+- and NaN::)
+-
+- `FP_INFINITE'
+- The value of X is either plus or minus infinity (*note
+- Infinity and NaN::)
+-
+- `FP_ZERO'
+- The value of X is zero. In floating-point formats like
+- IEEE 754, where zero can be signed, this value is also
+- returned if X is negative zero.
+-
+- `FP_SUBNORMAL'
+- Numbers whose absolute value is too small to be represented
+- in the normal format are represented in an alternate,
+- "denormalized" format (*note Floating Point Concepts::).
+- This format is less precise but can represent values closer
+- to zero. `fpclassify' returns this value for values of X in
+- this alternate format.
+-
+- `FP_NORMAL'
+- This value is returned for all other values of X. It
+- indicates that there is nothing special about the number.
+-
+-
+- `fpclassify' is most useful if more than one property of a number
+-must be tested. There are more specific macros which only test one
+-property at a time. Generally these macros execute faster than
+-`fpclassify', since there is special hardware support for them. You
+-should therefore use the specific macros whenever possible.
+-
+- - Macro: int isfinite (_float-type_ X)
+- This macro returns a nonzero value if X is finite: not plus or
+- minus infinity, and not NaN. It is equivalent to
+-
+- (fpclassify (x) != FP_NAN && fpclassify (x) != FP_INFINITE)
+-
+- `isfinite' is implemented as a macro which accepts any
+- floating-point type.
+-
+- - Macro: int isnormal (_float-type_ X)
+- This macro returns a nonzero value if X is finite and normalized.
+- It is equivalent to
+-
+- (fpclassify (x) == FP_NORMAL)
+-
+- - Macro: int isnan (_float-type_ X)
+- This macro returns a nonzero value if X is NaN. It is equivalent
+- to
+-
+- (fpclassify (x) == FP_NAN)
+-
+- Another set of floating-point classification functions was provided
+-by BSD. The GNU C library also supports these functions; however, we
+-recommend that you use the ISO C99 macros in new code. Those are
+-standard and will be available more widely. Also, since they are
+-macros, you do not have to worry about the type of their argument.
+-
+- - Function: int isinf (double X)
+- - Function: int isinff (float X)
+- - Function: int isinfl (long double X)
+- This function returns `-1' if X represents negative infinity, `1'
+- if X represents positive infinity, and `0' otherwise.
+-
+- - Function: int isnan (double X)
+- - Function: int isnanf (float X)
+- - Function: int isnanl (long double X)
+- This function returns a nonzero value if X is a "not a number"
+- value, and zero otherwise.
+-
+- *Note:* The `isnan' macro defined by ISO C99 overrides the BSD
+- function. This is normally not a problem, because the two
+- routines behave identically. However, if you really need to get
+- the BSD function for some reason, you can write
+-
+- (isnan) (x)
+-
+- - Function: int finite (double X)
+- - Function: int finitef (float X)
+- - Function: int finitel (long double X)
+- This function returns a nonzero value if X is finite or a "not a
+- number" value, and zero otherwise.

+- *Portability Note:* The functions listed in this section are BSD
+-extensions.

+-
+-FP Exceptions
+--------------
+-
+- The IEEE 754 standard defines five "exceptions" that can occur
+-during a calculation. Each corresponds to a particular sort of error,
+-such as overflow.
+-
+- When exceptions occur (when exceptions are "raised", in the language
+-of the standard), one of two things can happen. By default the
+-exception is simply noted in the floating-point "status word", and the
+-program continues as if nothing had happened. The operation produces a
+-default value, which depends on the exception (see the table below).
+-Your program can check the status word to find out which exceptions
+-happened.
+-
+- Alternatively, you can enable "traps" for exceptions. In that case,
+-when an exception is raised, your program will receive the `SIGFPE'
+-signal. The default action for this signal is to terminate the
+-program. *Note Signal Handling::, for how you can change the effect of
+-the signal.
+-
+- In the System V math library, the user-defined function `matherr' is
+-called when certain exceptions occur inside math library functions.
+-However, the Unix98 standard deprecates this interface. We support it
+-for historical compatibility, but recommend that you do not use it in
+-new programs.
+-
+-The exceptions defined in IEEE 754 are:
+-
+-`Invalid Operation'
+- This exception is raised if the given operands are invalid for the
+- operation to be performed. Examples are (see IEEE 754, section 7):
+- 1. Addition or subtraction: oo - oo. (But oo + oo = oo).
+-
+- 2. Multiplication: 0 * oo.
+-
+- 3. Division: 0/0 or oo/oo.
+-
+- 4. Remainder: x REM y, where y is zero or x is infinite.
+-
+- 5. Square root if the operand is less then zero. More
+- generally, any mathematical function evaluated outside its
+- domain produces this exception.
+-
+- 6. Conversion of a floating-point number to an integer or decimal
+- string, when the number cannot be represented in the target
+- format (due to overflow, infinity, or NaN).
+-
+- 7. Conversion of an unrecognizable input string.
+-
+- 8. Comparison via predicates involving < or >, when one or other
+- of the operands is NaN. You can prevent this exception by
+- using the unordered comparison functions instead; see *Note
+- FP Comparison Functions::.
+-
+- If the exception does not trap, the result of the operation is NaN.
+-
+-`Division by Zero'
+- This exception is raised when a finite nonzero number is divided
+- by zero. If no trap occurs the result is either +oo or -oo,
+- depending on the signs of the operands.
+-
+-`Overflow'
+- This exception is raised whenever the result cannot be represented
+- as a finite value in the precision format of the destination. If
+- no trap occurs the result depends on the sign of the intermediate
+- result and the current rounding mode (IEEE 754, section 7.3):
+- 1. Round to nearest carries all overflows to oo with the sign of
+- the intermediate result.
+-
+- 2. Round toward 0 carries all overflows to the largest
+- representable finite number with the sign of the intermediate
+- result.
+-
+- 3. Round toward -oo carries positive overflows to the largest
+- representable finite number and negative overflows to -oo.
+-
+- 4. Round toward oo carries negative overflows to the most
+- negative representable finite number and positive overflows
+- to oo.
+-
+- Whenever the overflow exception is raised, the inexact exception
+- is also raised.
+-
+-`Underflow'
+- The underflow exception is raised when an intermediate result is
+- too small to be calculated accurately, or if the operation's
+- result rounded to the destination precision is too small to be
+- normalized.
+-
+- When no trap is installed for the underflow exception, underflow is
+- signaled (via the underflow flag) only when both tininess and loss
+- of accuracy have been detected. If no trap handler is installed
+- the operation continues with an imprecise small value, or zero if
+- the destination precision cannot hold the small exact result.
+-
+-`Inexact'
+- This exception is signalled if a rounded result is not exact (such
+- as when calculating the square root of two) or a result overflows
+- without an overflow trap.

+-
+-Infinity and NaN
+-----------------
+-
+- IEEE 754 floating point numbers can represent positive or negative
+-infinity, and "NaN" (not a number). These three values arise from
+-calculations whose result is undefined or cannot be represented
+-accurately. You can also deliberately set a floating-point variable to
+-any of them, which is sometimes useful. Some examples of calculations
+-that produce infinity or NaN:
+-
+- 1/0 = oo
+- log (0) = -oo
+- sqrt (-1) = NaN
+-
+- When a calculation produces any of these values, an exception also
+-occurs; see *Note FP Exceptions::.
+-
+- The basic operations and math functions all accept infinity and NaN
+-and produce sensible output. Infinities propagate through calculations
+-as one would expect: for example, 2 + oo = oo, 4/oo = 0, atan (oo) =
+-pi/2. NaN, on the other hand, infects any calculation that involves
+-it. Unless the calculation would produce the same result no matter
+-what real value replaced NaN, the result is NaN.
+-
+- In comparison operations, positive infinity is larger than all values
+-except itself and NaN, and negative infinity is smaller than all values
+-except itself and NaN. NaN is "unordered": it is not equal to, greater
+-than, or less than anything, _including itself_. `x == x' is false if
+-the value of `x' is NaN. You can use this to test whether a value is
+-NaN or not, but the recommended way to test for NaN is with the `isnan'
+-function (*note Floating Point Classes::). In addition, `<', `>',
+-`<=', and `>=' will raise an exception when applied to NaNs.
+-
+- `math.h' defines macros that allow you to explicitly set a variable
+-to infinity or NaN.
+-
+- - Macro: float INFINITY
+- An expression representing positive infinity. It is equal to the
+- value produced by mathematical operations like `1.0 / 0.0'.
+- `-INFINITY' represents negative infinity.
+-
+- You can test whether a floating-point value is infinite by
+- comparing it to this macro. However, this is not recommended; you
+- should use the `isfinite' macro instead. *Note Floating Point
+- Classes::.
+-
+- This macro was introduced in the ISO C99 standard.
+-
+- - Macro: float NAN
+- An expression representing a value which is "not a number". This
+- macro is a GNU extension, available only on machines that support
+- the "not a number" value--that is to say, on all machines that
+- support IEEE floating point.
+-
+- You can use `#ifdef NAN' to test whether the machine supports NaN.
+- (Of course, you must arrange for GNU extensions to be visible,
+- such as by defining `_GNU_SOURCE', and then you must include
+- `math.h'.)
+-
+- IEEE 754 also allows for another unusual value: negative zero. This
+-value is produced when you divide a positive number by negative
+-infinity, or when a negative result is smaller than the limits of
+-representation. Negative zero behaves identically to zero in all
+-calculations, unless you explicitly test the sign bit with `signbit' or
+-`copysign'.

+-
+-Examining the FPU status word
+------------------------------
+-
+- ISO C99 defines functions to query and manipulate the floating-point
+-status word. You can use these functions to check for untrapped
+-exceptions when it's convenient, rather than worrying about them in the
+-middle of a calculation.
+-
+- These constants represent the various IEEE 754 exceptions. Not all
+-FPUs report all the different exceptions. Each constant is defined if
+-and only if the FPU you are compiling for supports that exception, so
+-you can test for FPU support with `#ifdef'. They are defined in
+-`fenv.h'.
+-
+-`FE_INEXACT'
+- The inexact exception.
+-
+-`FE_DIVBYZERO'
+- The divide by zero exception.
+-
+-`FE_UNDERFLOW'
+- The underflow exception.
+-
+-`FE_OVERFLOW'
+- The overflow exception.
+-
+-`FE_INVALID'
+- The invalid exception.
+-
+- The macro `FE_ALL_EXCEPT' is the bitwise OR of all exception macros
+-which are supported by the FP implementation.
+-
+- These functions allow you to clear exception flags, test for
+-exceptions, and save and restore the set of exceptions flagged.
+-
+- - Function: int feclearexcept (int EXCEPTS)
+- This function clears all of the supported exception flags
+- indicated by EXCEPTS.
+-
+- The function returns zero in case the operation was successful, a
+- non-zero value otherwise.
+-
+- - Function: int feraiseexcept (int EXCEPTS)
+- This function raises the supported exceptions indicated by
+- EXCEPTS. If more than one exception bit in EXCEPTS is set the
+- order in which the exceptions are raised is undefined except that
+- overflow (`FE_OVERFLOW') or underflow (`FE_UNDERFLOW') are raised
+- before inexact (`FE_INEXACT'). Whether for overflow or underflow
+- the inexact exception is also raised is also implementation
+- dependent.
+-
+- The function returns zero in case the operation was successful, a
+- non-zero value otherwise.
+-
+- - Function: int fetestexcept (int EXCEPTS)
+- Test whether the exception flags indicated by the parameter EXCEPT
+- are currently set. If any of them are, a nonzero value is returned
+- which specifies which exceptions are set. Otherwise the result is
+- zero.
+-
+- To understand these functions, imagine that the status word is an
+-integer variable named STATUS. `feclearexcept' is then equivalent to
+-`status &= ~excepts' and `fetestexcept' is equivalent to `(status &
+-excepts)'. The actual implementation may be very different, of course.
+-
+- Exception flags are only cleared when the program explicitly
+-requests it, by calling `feclearexcept'. If you want to check for
+-exceptions from a set of calculations, you should clear all the flags
+-first. Here is a simple example of the way to use `fetestexcept':
+-
+- {
+- double f;
+- int raised;
+- feclearexcept (FE_ALL_EXCEPT);
+- f = compute ();
+- raised = fetestexcept (FE_OVERFLOW | FE_INVALID);
+- if (raised & FE_OVERFLOW) { /* ... */ }
+- if (raised & FE_INVALID) { /* ... */ }
+- /* ... */
+- }
+-
+- You cannot explicitly set bits in the status word. You can, however,
+-save the entire status word and restore it later. This is done with the
+-following functions:
+-
+- - Function: int fegetexceptflag (fexcept_t *FLAGP, int EXCEPTS)
+- This function stores in the variable pointed to by FLAGP an
+- implementation-defined value representing the current setting of
+- the exception flags indicated by EXCEPTS.
+-
+- The function returns zero in case the operation was successful, a
+- non-zero value otherwise.
+-
+- - Function: int fesetexceptflag (const fexcept_t *FLAGP, int
+- EXCEPTS) This function restores the flags for the exceptions
+- indicated by EXCEPTS to the values stored in the variable pointed
+- to by FLAGP.
+-
+- The function returns zero in case the operation was successful, a
+- non-zero value otherwise.
+-
+- Note that the value stored in `fexcept_t' bears no resemblance to
+-the bit mask returned by `fetestexcept'. The type may not even be an
+-integer. Do not attempt to modify an `fexcept_t' variable.

+-Error Reporting by Mathematical Functions
+------------------------------------------
+-
+- Many of the math functions are defined only over a subset of the
+-real or complex numbers. Even if they are mathematically defined,
+-their result may be larger or smaller than the range representable by
+-their return type. These are known as "domain errors", "overflows", and
+-"underflows", respectively. Math functions do several things when one
+-of these errors occurs. In this manual we will refer to the complete
+-response as "signalling" a domain error, overflow, or underflow.
+-
+- When a math function suffers a domain error, it raises the invalid
+-exception and returns NaN. It also sets ERRNO to `EDOM'; this is for
+-compatibility with old systems that do not support IEEE 754 exception
+-handling. Likewise, when overflow occurs, math functions raise the
+-overflow exception and return oo or -oo as appropriate. They also set
+-ERRNO to `ERANGE'. When underflow occurs, the underflow exception is
+-raised, and zero (appropriately signed) is returned. ERRNO may be set
+-to `ERANGE', but this is not guaranteed.
+-
+- Some of the math functions are defined mathematically to result in a
+-complex value over parts of their domains. The most familiar example of
+-this is taking the square root of a negative number. The complex math
+-functions, such as `csqrt', will return the appropriate complex value
+-in this case. The real-valued functions, such as `sqrt', will signal a
+-domain error.
+-
+- Some older hardware does not support infinities. On that hardware,
+-overflows instead return a particular very large number (usually the
+-largest representable number). `math.h' defines macros you can use to
+-test for overflow on both old and new hardware.
+-
+- - Macro: double HUGE_VAL
+- - Macro: float HUGE_VALF
+- - Macro: long double HUGE_VALL
+- An expression representing a particular very large number. On
+- machines that use IEEE 754 floating point format, `HUGE_VAL' is
+- infinity. On other machines, it's typically the largest positive
+- number that can be represented.
+-
+- Mathematical functions return the appropriately typed version of
+- `HUGE_VAL' or `-HUGE_VAL' when the result is too large to be
+- represented.

+-
+-Rounding Modes
+-==============
+-
+- Floating-point calculations are carried out internally with extra
+-precision, and then rounded to fit into the destination type. This
+-ensures that results are as precise as the input data. IEEE 754
+-defines four possible rounding modes:
+-
+-Round to nearest.
+- This is the default mode. It should be used unless there is a
+- specific need for one of the others. In this mode results are
+- rounded to the nearest representable value. If the result is
+- midway between two representable values, the even representable is
+- chosen. "Even" here means the lowest-order bit is zero. This
+- rounding mode prevents statistical bias and guarantees numeric
+- stability: round-off errors in a lengthy calculation will remain
+- smaller than half of `FLT_EPSILON'.
+-
+-Round toward plus Infinity.
+- All results are rounded to the smallest representable value which
+- is greater than the result.
+-
+-Round toward minus Infinity.
+- All results are rounded to the largest representable value which
+- is less than the result.
+-
+-Round toward zero.
+- All results are rounded to the largest representable value whose
+- magnitude is less than that of the result. In other words, if the
+- result is negative it is rounded up; if it is positive, it is
+- rounded down.
+-
+-`fenv.h' defines constants which you can use to refer to the various
+-rounding modes. Each one will be defined if and only if the FPU
+-supports the corresponding rounding mode.
+-
+-`FE_TONEAREST'
+- Round to nearest.
+-
+-`FE_UPWARD'
+- Round toward +oo.
+-
+-`FE_DOWNWARD'
+- Round toward -oo.
+-
+-`FE_TOWARDZERO'
+- Round toward zero.
+-
+- Underflow is an unusual case. Normally, IEEE 754 floating point
+-numbers are always normalized (*note Floating Point Concepts::).
+-Numbers smaller than 2^r (where r is the minimum exponent,
+-`FLT_MIN_RADIX-1' for FLOAT) cannot be represented as normalized
+-numbers. Rounding all such numbers to zero or 2^r would cause some
+-algorithms to fail at 0. Therefore, they are left in denormalized
+-form. That produces loss of precision, since some bits of the mantissa
+-are stolen to indicate the decimal point.
+-
+- If a result is too small to be represented as a denormalized number,
+-it is rounded to zero. However, the sign of the result is preserved; if
+-the calculation was negative, the result is "negative zero". Negative
+-zero can also result from some operations on infinity, such as 4/-oo.
+-Negative zero behaves identically to zero except when the `copysign' or
+-`signbit' functions are used to check the sign bit directly.
+-
+- At any time one of the above four rounding modes is selected. You
+-can find out which one with this function:
+-
+- - Function: int fegetround (void)
+- Returns the currently selected rounding mode, represented by one
+- of the values of the defined rounding mode macros.
+-
+-To change the rounding mode, use this function:
+-
+- - Function: int fesetround (int ROUND)
+- Changes the currently selected rounding mode to ROUND. If ROUND
+- does not correspond to one of the supported rounding modes nothing
+- is changed. `fesetround' returns zero if it changed the rounding
+- mode, a nonzero value if the mode is not supported.
+-
+- You should avoid changing the rounding mode if possible. It can be
+-an expensive operation; also, some hardware requires you to compile your
+-program differently for it to work. The resulting code may run slower.
+-See your compiler documentation for details.

+-Floating-Point Control Functions
+-================================
+-
+- IEEE 754 floating-point implementations allow the programmer to
+-decide whether traps will occur for each of the exceptions, by setting
+-bits in the "control word". In C, traps result in the program
+-receiving the `SIGFPE' signal; see *Note Signal Handling::.
+-
+- *Note:* IEEE 754 says that trap handlers are given details of the
+-exceptional situation, and can set the result value. C signals do not
+-provide any mechanism to pass this information back and forth.
+-Trapping exceptions in C is therefore not very useful.
+-
+- It is sometimes necessary to save the state of the floating-point
+-unit while you perform some calculation. The library provides functions
+-which save and restore the exception flags, the set of exceptions that
+-generate traps, and the rounding mode. This information is known as the
+-"floating-point environment".
+-
+- The functions to save and restore the floating-point environment all
+-use a variable of type `fenv_t' to store information. This type is
+-defined in `fenv.h'. Its size and contents are implementation-defined.
+-You should not attempt to manipulate a variable of this type directly.
+-
+- To save the state of the FPU, use one of these functions:
+-
+- - Function: int fegetenv (fenv_t *ENVP)
+- Store the floating-point environment in the variable pointed to by
+- ENVP.
+-
+- The function returns zero in case the operation was successful, a
+- non-zero value otherwise.
+-
+- - Function: int feholdexcept (fenv_t *ENVP)
+- Store the current floating-point environment in the object pointed
+- to by ENVP. Then clear all exception flags, and set the FPU to
+- trap no exceptions. Not all FPUs support trapping no exceptions;
+- if `feholdexcept' cannot set this mode, it returns nonzero value.
+- If it succeeds, it returns zero.
+-
+- The functions which restore the floating-point environment can take
+-these kinds of arguments:
+-
+- * Pointers to `fenv_t' objects, which were initialized previously by
+- a call to `fegetenv' or `feholdexcept'.
+-
+- * The special macro `FE_DFL_ENV' which represents the floating-point
+- environment as it was available at program start.
+-
+- * Implementation defined macros with names starting with `FE_' and
+- having type `fenv_t *'.
+-
+- If possible, the GNU C Library defines a macro `FE_NOMASK_ENV'
+- which represents an environment where every exception raised
+- causes a trap to occur. You can test for this macro using
+- `#ifdef'. It is only defined if `_GNU_SOURCE' is defined.
+-
+- Some platforms might define other predefined environments.
+-
+-To set the floating-point environment, you can use either of these
+-functions:
+-
+- - Function: int fesetenv (const fenv_t *ENVP)
+- Set the floating-point environment to that described by ENVP.
+-
+- The function returns zero in case the operation was successful, a
+- non-zero value otherwise.
+-
+- - Function: int feupdateenv (const fenv_t *ENVP)
+- Like `fesetenv', this function sets the floating-point environment
+- to that described by ENVP. However, if any exceptions were
+- flagged in the status word before `feupdateenv' was called, they
+- remain flagged after the call. In other words, after `feupdateenv'
+- is called, the status word is the bitwise OR of the previous
+- status word and the one saved in ENVP.
+-
+- The function returns zero in case the operation was successful, a
+- non-zero value otherwise.
+-
+-To control for individual exceptions if raising them causes a trap to
+-occur, you can use the following two functions.
+-
+- *Portability Note:* These functions are all GNU extensions.
+-
+- - Function: int feenableexcept (int EXCEPTS)
+- This functions enables traps for each of the exceptions as
+- indicated by the parameter EXCEPT. The individual excepetions are
+- described in *Note Status bit operations::. Only the specified
+- exceptions are enabled, the status of the other exceptions is not
+- changed.
+-
+- The function returns the previous enabled exceptions in case the
+- operation was successful, `-1' otherwise.
+-
+- - Function: int fedisableexcept (int EXCEPTS)
+- This functions disables traps for each of the exceptions as
+- indicated by the parameter EXCEPT. The individual excepetions are
+- described in *Note Status bit operations::. Only the specified
+- exceptions are disabled, the status of the other exceptions is not
+- changed.
+-
+- The function returns the previous enabled exceptions in case the
+- operation was successful, `-1' otherwise.
+-
+- - Function: int fegetexcept (int EXCEPTS)
+- The function returns a bitmask of all currently enabled
+- exceptions. It returns `-1' in case of failure.

+-
+- These functions are provided for obtaining the "absolute value" (or

+-if X is positive, -X if X is negative. For a complex number Z, whose
+-real part is X and whose imaginary part is Y, the absolute value is
+-`sqrt (X*X + Y*Y)'.

+-declared in `math.h'. `cabs', `cabsf' and `cabsl' are declared in
+-`complex.h'.
+-
+- - Function: int abs (int NUMBER)
+- - Function: long int labs (long int NUMBER)
+- - Function: long long int llabs (long long int NUMBER)
+- - Function: intmax_t imaxabs (intmax_t NUMBER)
+- These functions return the absolute value of NUMBER.

+-Normalization Functions
+------------------------
+-
+- The functions described in this section are primarily provided as a
+-way to efficiently perform certain low-level manipulations on floating
+-point numbers that are represented internally using a binary radix; see
+-*Note Floating Point Concepts::. These functions are required to have
+-equivalent behavior even if the representation does not use a radix of
+-2, but of course they are unlikely to be particularly efficient in
+-those cases.
+-
+- All these functions are declared in `math.h'.
+-
+- - Function: double frexp (double VALUE, int *EXPONENT)
+- - Function: float frexpf (float VALUE, int *EXPONENT)
+- - Function: long double frexpl (long double VALUE, int *EXPONENT)
+- These functions are used to split the number VALUE into a
+- normalized fraction and an exponent.
+-
+- If the argument VALUE is not zero, the return value is VALUE times
+- a power of two, and is always in the range 1/2 (inclusive) to 1
+- (exclusive). The corresponding exponent is stored in `*EXPONENT';
+- the return value multiplied by 2 raised to this exponent equals
+- the original number VALUE.
+-
+- For example, `frexp (12.8, &exponent)' returns `0.8' and stores
+- `4' in `exponent'.
+-
+- If VALUE is zero, then the return value is zero and zero is stored
+- in `*EXPONENT'.
+-
+- - Function: double ldexp (double VALUE, int EXPONENT)
+- - Function: float ldexpf (float VALUE, int EXPONENT)
+- - Function: long double ldexpl (long double VALUE, int EXPONENT)
+- These functions return the result of multiplying the floating-point
+- number VALUE by 2 raised to the power EXPONENT. (It can be used
+- to reassemble floating-point numbers that were taken apart by
+- `frexp'.)
+-
+- For example, `ldexp (0.8, 4)' returns `12.8'.
+-
+- The following functions, which come from BSD, provide facilities
+-equivalent to those of `ldexp' and `frexp'. See also the ISO C
+-function `logb' which originally also appeared in BSD.
+-
+- - Function: double scalb (double VALUE, int EXPONENT)
+- - Function: float scalbf (float VALUE, int EXPONENT)
+- - Function: long double scalbl (long double VALUE, int EXPONENT)
+- The `scalb' function is the BSD name for `ldexp'.
+-
+- - Function: long long int scalbn (double X, int n)
+- - Function: long long int scalbnf (float X, int n)
+- - Function: long long int scalbnl (long double X, int n)
+- `scalbn' is identical to `scalb', except that the exponent N is an
+- `int' instead of a floating-point number.
+-
+- - Function: long long int scalbln (double X, long int n)
+- - Function: long long int scalblnf (float X, long int n)
+- - Function: long long int scalblnl (long double X, long int n)
+- `scalbln' is identical to `scalb', except that the exponent N is a
+- `long int' instead of a floating-point number.
+-
+- - Function: long long int significand (double X)
+- - Function: long long int significandf (float X)
+- - Function: long long int significandl (long double X)
+- `significand' returns the mantissa of X scaled to the range [1, 2).
+- It is equivalent to `scalb (X, (double) -ilogb (X))'.
+-
+- This function exists mainly for use in certain standardized tests
+- of IEEE 754 conformance.

+-Rounding Functions
+-------------------
+-
+- The functions listed here perform operations such as rounding and
+-truncation of floating-point values. Some of these functions convert
+-floating point numbers to integer values. They are all declared in
+-`math.h'.
+-
+- You can also convert floating-point numbers to integers simply by
+-casting them to `int'. This discards the fractional part, effectively
+-rounding towards zero. However, this only works if the result can
+-actually be represented as an `int'--for very large numbers, this is
+-impossible. The functions listed here return the result as a `double'
+-instead to get around this problem.
+-
+- - Function: double ceil (double X)
+- - Function: float ceilf (float X)
+- - Function: long double ceill (long double X)
+- These functions round X upwards to the nearest integer, returning
+- that value as a `double'. Thus, `ceil (1.5)' is `2.0'.
+-
+- - Function: double floor (double X)
+- - Function: float floorf (float X)
+- - Function: long double floorl (long double X)
+- These functions round X downwards to the nearest integer,
+- returning that value as a `double'. Thus, `floor (1.5)' is `1.0'
+- and `floor (-1.5)' is `-2.0'.
+-
+- - Function: double trunc (double X)
+- - Function: float truncf (float X)
+- - Function: long double truncl (long double X)
+- The `trunc' functions round X towards zero to the nearest integer
+- (returned in floating-point format). Thus, `trunc (1.5)' is `1.0'
+- and `trunc (-1.5)' is `-1.0'.
+-
+- - Function: double rint (double X)
+- - Function: float rintf (float X)
+- - Function: long double rintl (long double X)
+- These functions round X to an integer value according to the
+- current rounding mode. *Note Floating Point Parameters::, for
+- information about the various rounding modes. The default
+- rounding mode is to round to the nearest integer; some machines
+- support other modes, but round-to-nearest is always used unless
+- you explicitly select another.
+-
+- If X was not initially an integer, these functions raise the
+- inexact exception.
+-
+- - Function: double nearbyint (double X)
+- - Function: float nearbyintf (float X)
+- - Function: long double nearbyintl (long double X)
+- These functions return the same value as the `rint' functions, but
+- do not raise the inexact exception if X is not an integer.
+-
+- - Function: double round (double X)
+- - Function: float roundf (float X)
+- - Function: long double roundl (long double X)
+- These functions are similar to `rint', but they round halfway
+- cases away from zero instead of to the nearest even integer.
+-
+- - Function: long int lrint (double X)
+- - Function: long int lrintf (float X)
+- - Function: long int lrintl (long double X)
+- These functions are just like `rint', but they return a `long int'
+- instead of a floating-point number.
+-
+- - Function: long long int llrint (double X)
+- - Function: long long int llrintf (float X)
+- - Function: long long int llrintl (long double X)
+- These functions are just like `rint', but they return a `long long
+- int' instead of a floating-point number.
+-
+- - Function: long int lround (double X)
+- - Function: long int lroundf (float X)
+- - Function: long int lroundl (long double X)
+- These functions are just like `round', but they return a `long
+- int' instead of a floating-point number.
+-
+- - Function: long long int llround (double X)
+- - Function: long long int llroundf (float X)
+- - Function: long long int llroundl (long double X)
+- These functions are just like `round', but they return a `long
+- long int' instead of a floating-point number.
+-
+- - Function: double modf (double VALUE, double *INTEGER-PART)
+- - Function: float modff (float VALUE, float *INTEGER-PART)
+- - Function: long double modfl (long double VALUE, long double
+- *INTEGER-PART)
+- These functions break the argument VALUE into an integer part and a
+- fractional part (between `-1' and `1', exclusive). Their sum
+- equals VALUE. Each of the parts has the same sign as VALUE, and
+- the integer part is always rounded toward zero.
+-
+- `modf' stores the integer part in `*INTEGER-PART', and returns the
+- fractional part. For example, `modf (2.5, &intpart)' returns
+- `0.5' and stores `2.0' into `intpart'.

+-Remainder Functions
+--------------------
+-
+- The functions in this section compute the remainder on division of
+-two floating-point numbers. Each is a little different; pick the one
+-that suits your problem.
+-
+- - Function: double fmod (double NUMERATOR, double DENOMINATOR)
+- - Function: float fmodf (float NUMERATOR, float DENOMINATOR)
+- - Function: long double fmodl (long double NUMERATOR, long double
+- DENOMINATOR)
+- These functions compute the remainder from the division of
+- NUMERATOR by DENOMINATOR. Specifically, the return value is
+- `NUMERATOR - N * DENOMINATOR', where N is the quotient of
+- NUMERATOR divided by DENOMINATOR, rounded towards zero to an
+- integer. Thus, `fmod (6.5, 2.3)' returns `1.9', which is `6.5'
+- minus `4.6'.
+-
+- The result has the same sign as the NUMERATOR and has magnitude
+- less than the magnitude of the DENOMINATOR.
+-
+- If DENOMINATOR is zero, `fmod' signals a domain error.
+-
+- - Function: double drem (double NUMERATOR, double DENOMINATOR)
+- - Function: float dremf (float NUMERATOR, float DENOMINATOR)
+- - Function: long double dreml (long double NUMERATOR, long double
+- DENOMINATOR)
+- These functions are like `fmod' except that they rounds the
+- internal quotient N to the nearest integer instead of towards zero
+- to an integer. For example, `drem (6.5, 2.3)' returns `-0.4',
+- which is `6.5' minus `6.9'.
+-
+- The absolute value of the result is less than or equal to half the
+- absolute value of the DENOMINATOR. The difference between `fmod
+- (NUMERATOR, DENOMINATOR)' and `drem (NUMERATOR, DENOMINATOR)' is
+- always either DENOMINATOR, minus DENOMINATOR, or zero.
+-
+- If DENOMINATOR is zero, `drem' signals a domain error.

+- - Function: double remainder (double NUMERATOR, double DENOMINATOR)
+- - Function: float remainderf (float NUMERATOR, float DENOMINATOR)

+-Setting and modifying single bits of FP values
+-----------------------------------------------
+-
+- There are some operations that are too complicated or expensive to
+-perform by hand on floating-point numbers. ISO C99 defines functions
+-to do these operations, which mostly involve changing single bits.
+-
+- - Function: double copysign (double X, double Y)
+- - Function: float copysignf (float X, float Y)
+- - Function: long double copysignl (long double X, long double Y)
+- These functions return X but with the sign of Y. They work even
+- if X or Y are NaN or zero. Both of these can carry a sign
+- (although not all implementations support it) and this is one of
+- the few operations that can tell the difference.
+-
+- `copysign' never raises an exception.
+-
+- This function is defined in IEC 559 (and the appendix with
+- recommended functions in IEEE 754/IEEE 854).
+-
+- - Function: int signbit (_float-type_ X)
+- `signbit' is a generic macro which can work on all floating-point
+- types. It returns a nonzero value if the value of X has its sign
+- bit set.
+-
+- This is not the same as `x < 0.0', because IEEE 754 floating point
+- allows zero to be signed. The comparison `-0.0 < 0.0' is false,
+- but `signbit (-0.0)' will return a nonzero value.
+-
+- - Function: double nextafter (double X, double Y)
+- - Function: float nextafterf (float X, float Y)
+- - Function: long double nextafterl (long double X, long double Y)
+- The `nextafter' function returns the next representable neighbor of
+- X in the direction towards Y. The size of the step between X and
+- the result depends on the type of the result. If X = Y the
+- function simply returns Y. If either value is `NaN', `NaN' is
+- returned. Otherwise a value corresponding to the value of the
+- least significant bit in the mantissa is added or subtracted,
+- depending on the direction. `nextafter' will signal overflow or
+- underflow if the result goes outside of the range of normalized
+- numbers.
+-
+- This function is defined in IEC 559 (and the appendix with
+- recommended functions in IEEE 754/IEEE 854).
+-
+- - Function: double nexttoward (double X, long double Y)
+- - Function: float nexttowardf (float X, long double Y)
+- - Function: long double nexttowardl (long double X, long double Y)
+- These functions are identical to the corresponding versions of
+- `nextafter' except that their second argument is a `long double'.
+-
+- - Function: double nan (const char *TAGP)
+- - Function: float nanf (const char *TAGP)
+- - Function: long double nanl (const char *TAGP)
+- The `nan' function returns a representation of NaN, provided that
+- NaN is supported by the target platform. `nan
+- ("N-CHAR-SEQUENCE")' is equivalent to `strtod
+- ("NAN(N-CHAR-SEQUENCE)")'.
+-
+- The argument TAGP is used in an unspecified manner. On IEEE 754
+- systems, there are many representations of NaN, and TAGP selects
+- one. On other systems it may do nothing.

+-Floating-Point Comparison Functions
+------------------------------------
+-
+- The standard C comparison operators provoke exceptions when one or
+-other of the operands is NaN. For example,
+-
+- int v = a < 1.0;
+-
+-will raise an exception if A is NaN. (This does _not_ happen with `=='
+-and `!='; those merely return false and true, respectively, when NaN is
+-examined.) Frequently this exception is undesirable. ISO C99
+-therefore defines comparison functions that do not raise exceptions
+-when NaN is examined. All of the functions are implemented as macros
+-which allow their arguments to be of any floating-point type. The
+-macros are guaranteed to evaluate their arguments only once.
+-
+- - Macro: int isgreater (_real-floating_ X, _real-floating_ Y)
+- This macro determines whether the argument X is greater than Y.
+- It is equivalent to `(X) > (Y)', but no exception is raised if X
+- or Y are NaN.
+-
+- - Macro: int isgreaterequal (_real-floating_ X, _real-floating_ Y)
+- This macro determines whether the argument X is greater than or
+- equal to Y. It is equivalent to `(X) >= (Y)', but no exception is
+- raised if X or Y are NaN.
+-
+- - Macro: int isless (_real-floating_ X, _real-floating_ Y)
+- This macro determines whether the argument X is less than Y. It
+- is equivalent to `(X) < (Y)', but no exception is raised if X or Y
+- are NaN.
+-
+- - Macro: int islessequal (_real-floating_ X, _real-floating_ Y)
+- This macro determines whether the argument X is less than or equal
+- to Y. It is equivalent to `(X) <= (Y)', but no exception is
+- raised if X or Y are NaN.
+-
+- - Macro: int islessgreater (_real-floating_ X, _real-floating_ Y)
+- This macro determines whether the argument X is less or greater
+- than Y. It is equivalent to `(X) < (Y) || (X) > (Y)' (although it
+- only evaluates X and Y once), but no exception is raised if X or Y
+- are NaN.
+-
+- This macro is not equivalent to `X != Y', because that expression
+- is true if X or Y are NaN.
+-
+- - Macro: int isunordered (_real-floating_ X, _real-floating_ Y)
+- This macro determines whether its arguments are unordered. In
+- other words, it is true if X or Y are NaN, and false otherwise.
+-
+- Not all machines provide hardware support for these operations. On
+-machines that don't, the macros can be very slow. Therefore, you should
+-not use these functions when NaN is not a concern.
+-
+- *Note:* There are no macros `isequal' or `isunequal'. They are
+-unnecessary, because the `==' and `!=' operators do _not_ throw an
+-exception if one or both of the operands are NaN.

+-Miscellaneous FP arithmetic functions
+--------------------------------------
+-
+- The functions in this section perform miscellaneous but common

+-perform these operations faster than the equivalent C code.
+-
+- - Function: double fmin (double X, double Y)
+- - Function: float fminf (float X, float Y)

+- The `fmin' function returns the lesser of the two values X and Y.
+- It is similar to the expression
+- ((x) < (y) ? (x) : (y))
+- except that X and Y are only evaluated once.
+-
+- If an argument is NaN, the other argument is returned. If both
+- arguments are NaN, NaN is returned.
+-
+- - Function: double fmax (double X, double Y)
+- - Function: float fmaxf (float X, float Y)
+- - Function: long double fmaxl (long double X, long double Y)
+- The `fmax' function returns the greater of the two values X and Y.
+-
+- If an argument is NaN, the other argument is returned. If both
+- arguments are NaN, NaN is returned.
+-
+- - Function: double fdim (double X, double Y)
+- - Function: float fdimf (float X, float Y)
+- - Function: long double fdiml (long double X, long double Y)
+- The `fdim' function returns the positive difference between X and
+- Y. The positive difference is X - Y if X is greater than Y, and 0
+- otherwise.
+-
+- If X, Y, or both are NaN, NaN is returned.
+-
+- - Function: double fma (double X, double Y, double Z)
+- - Function: float fmaf (float X, float Y, float Z)
+- - Function: long double fmal (long double X, long double Y, long
+- double Z)
+- The `fma' function performs floating-point multiply-add. This is
+- the operation (X * Y) + Z, but the intermediate result is not
+- rounded to the destination type. This can sometimes improve the
+- precision of a calculation.
+-
+- This function was introduced because some processors have a special
+- instruction to perform multiply-add. The C compiler cannot use it
+- directly, because the expression `x*y + z' is defined to round the
+- intermediate result. `fma' lets you choose when you want to round
+- only once.
+-
+- On processors which do not implement multiply-add in hardware,
+- `fma' can be very slow since it must avoid intermediate rounding.
+- `math.h' defines the symbols `FP_FAST_FMA', `FP_FAST_FMAF', and
+- `FP_FAST_FMAL' when the corresponding version of `fma' is no
+- slower than the expression `x*y + z'. In the GNU C library, this
+- always means the operation is implemented in hardware.

+-Complex Numbers
+-===============
+-
+- ISO C99 introduces support for complex numbers in C. This is done
+-with a new type qualifier, `complex'. It is a keyword if and only if
+-`complex.h' has been included. There are three complex types,
+-corresponding to the three real types: `float complex', `double
+-complex', and `long double complex'.
+-
+- To construct complex numbers you need a way to indicate the imaginary
+-part of a number. There is no standard notation for an imaginary
+-floating point constant. Instead, `complex.h' defines two macros that
+-can be used to create complex numbers.
+-
+- - Macro: const float complex _Complex_I
+- This macro is a representation of the complex number "0+1i".
+- Multiplying a real floating-point value by `_Complex_I' gives a
+- complex number whose value is purely imaginary. You can use this
+- to construct complex constants:
+-
+- 3.0 + 4.0i = `3.0 + 4.0 * _Complex_I'
+-
+- Note that `_Complex_I * _Complex_I' has the value `-1', but the
+- type of that value is `complex'.
+-
+-`_Complex_I' is a bit of a mouthful. `complex.h' also defines a
+-shorter name for the same constant.
+-
+- - Macro: const float complex I
+- This macro has exactly the same value as `_Complex_I'. Most of the
+- time it is preferable. However, it causes problems if you want to
+- use the identifier `I' for something else. You can safely write
+-
+- #include <complex.h>
+- #undef I
+-
+- if you need `I' for your own purposes. (In that case we recommend
+- you also define some other short name for `_Complex_I', such as
+- `J'.)

+-===========================================================
+-
+- ISO C99 also defines functions that perform basic operations on
+-complex numbers, such as decomposition and conjugation. The prototypes
+-for all these functions are in `complex.h'. All functions are
+-available in three variants, one for each of the three complex types.
+-
+- - Function: double creal (complex double Z)

+- - Function: float cimagf (complex float Z)
+- - Function: long double cimagl (complex long double Z)
+- These functions return the imaginary part of the complex number Z.
+-
+- - Function: complex double conj (complex double Z)
+- - Function: complex float conjf (complex float Z)
+- - Function: complex long double conjl (complex long double Z)
+- These functions return the conjugate value of the complex number
+- Z. The conjugate of a complex number has the same real part and a
+- negated imaginary part. In other words, `conj(a + bi) = a + -bi'.
+-
+- - Function: double carg (complex double Z)
+- - Function: float cargf (complex float Z)
+- - Function: long double cargl (complex long double Z)
+- These functions return the argument of the complex number Z. The
+- argument of a complex number is the angle in the complex plane
+- between the positive real axis and a line passing through zero and
+- the number. This angle is measured in the usual fashion and
+- ranges from 0 to 2pi.
+-
+- `carg' has a branch cut along the positive real axis.
+-
+- - Function: complex double cproj (complex double Z)
+- - Function: complex float cprojf (complex float Z)
+- - Function: complex long double cprojl (complex long double Z)
+- These functions return the projection of the complex value Z onto
+- the Riemann sphere. Values with a infinite imaginary part are

+-Parsing of Integers
+--------------------
+-
+- The `str' functions are declared in `stdlib.h' and those beginning
+-with `wcs' are declared in `wchar.h'. One might wonder about the use
+-of `restrict' in the prototypes of the functions in this section. It
+-is seemingly useless but the ISO C standard uses it (for the functions
+-defined there) so we have to do it as well.
+-
+- - Function: long int strtol (const char *restrict STRING, char
+- **restrict TAILPTR, int BASE)
+- The `strtol' ("string-to-long") function converts the initial part
+- of STRING to a signed integer, which is returned as a value of
+- type `long int'.
+-
+- This function attempts to decompose STRING as follows:
+-
+- * A (possibly empty) sequence of whitespace characters. Which
+- characters are whitespace is determined by the `isspace'
+- function (*note Classification of Characters::). These are
+- discarded.
+-
+- * An optional plus or minus sign (`+' or `-').
+-
+- * A nonempty sequence of digits in the radix specified by BASE.
+-
+- If BASE is zero, decimal radix is assumed unless the series of
+- digits begins with `0' (specifying octal radix), or `0x' or
+- `0X' (specifying hexadecimal radix); in other words, the same
+- syntax used for integer constants in C.
+-
+- Otherwise BASE must have a value between `2' and `36'. If
+- BASE is `16', the digits may optionally be preceded by `0x'
+- or `0X'. If base has no legal value the value returned is
+- `0l' and the global variable `errno' is set to `EINVAL'.
+-
+- * Any remaining characters in the string. If TAILPTR is not a
+- null pointer, `strtol' stores a pointer to this tail in
+- `*TAILPTR'.
+-
+- If the string is empty, contains only whitespace, or does not
+- contain an initial substring that has the expected syntax for an
+- integer in the specified BASE, no conversion is performed. In
+- this case, `strtol' returns a value of zero and the value stored in
+- `*TAILPTR' is the value of STRING.
+-
+- In a locale other than the standard `"C"' locale, this function
+- may recognize additional implementation-dependent syntax.
+-
+- If the string has valid syntax for an integer but the value is not
+- representable because of overflow, `strtol' returns either
+- `LONG_MAX' or `LONG_MIN' (*note Range of Type::), as appropriate
+- for the sign of the value. It also sets `errno' to `ERANGE' to
+- indicate there was overflow.
+-
+- You should not check for errors by examining the return value of
+- `strtol', because the string might be a valid representation of
+- `0l', `LONG_MAX', or `LONG_MIN'. Instead, check whether TAILPTR
+- points to what you expect after the number (e.g. `'\0'' if the
+- string should end after the number). You also need to clear ERRNO
+- before the call and check it afterward, in case there was overflow.
+-
+- There is an example at the end of this section.
+-
+- - Function: long int wcstol (const wchar_t *restrict STRING, wchar_t
+- **restrict TAILPTR, int BASE)
+- The `wcstol' function is equivalent to the `strtol' function in
+- nearly all aspects but handles wide character strings.
+-
+- The `wcstol' function was introduced in Amendment 1 of ISO C90.
+-
+- - Function: unsigned long int strtoul (const char *retrict STRING,

+- returned on overflow is `ULONG_MAX' (*note Range of Type::).
+-
+- If STRING depicts a negative number, `strtoul' acts the same as

+- The `wcstoumax' function was introduced in ISO C99.
+-
+- - Function: long int atol (const char *STRING)
+- This function is similar to the `strtol' function with a BASE
+- argument of `10', except that it need not detect overflow errors.
+- The `atol' function is provided mostly for compatibility with
+- existing code; using `strtol' is more robust.
+-
+- - Function: int atoi (const char *STRING)
+- This function is like `atol', except that it returns an `int'.
+- The `atoi' function is also considered obsolete; use `strtol'

+-
+-Parsing of Floats
+------------------
+-
+- The `str' functions are declared in `stdlib.h' and those beginning
+-with `wcs' are declared in `wchar.h'. One might wonder about the use
+-of `restrict' in the prototypes of the functions in this section. It
+-is seemingly useless but the ISO C standard uses it (for the functions
+-defined there) so we have to do it as well.
+-
+- - Function: double strtod (const char *restrict STRING, char
+- **restrict TAILPTR)
+- The `strtod' ("string-to-double") function converts the initial
+- part of STRING to a floating-point number, which is returned as a
+- value of type `double'.
+-
+- This function attempts to decompose STRING as follows:
+-
+- * A (possibly empty) sequence of whitespace characters. Which
+- characters are whitespace is determined by the `isspace'
+- function (*note Classification of Characters::). These are
+- discarded.
+-
+- * An optional plus or minus sign (`+' or `-').
+-
+- * A floating point number in decimal or hexadecimal format. The
+- decimal format is:
+- - A nonempty sequence of digits optionally containing a
+- decimal-point character--normally `.', but it depends on
+- the locale (*note General Numeric::).
+-
+- - An optional exponent part, consisting of a character `e'
+- or `E', an optional sign, and a sequence of digits.
+-
+-
+- The hexadecimal format is as follows:
+- - A 0x or 0X followed by a nonempty sequence of
+- hexadecimal digits optionally containing a decimal-point
+- character--normally `.', but it depends on the locale
+- (*note General Numeric::).
+-
+- - An optional binary-exponent part, consisting of a
+- character `p' or `P', an optional sign, and a sequence
+- of digits.
+-
+-
+- * Any remaining characters in the string. If TAILPTR is not a
+- null pointer, a pointer to this tail of the string is stored
+- in `*TAILPTR'.
+-
+- If the string is empty, contains only whitespace, or does not
+- contain an initial substring that has the expected syntax for a
+- floating-point number, no conversion is performed. In this case,
+- `strtod' returns a value of zero and the value returned in
+- `*TAILPTR' is the value of STRING.
+-
+- In a locale other than the standard `"C"' or `"POSIX"' locales,
+- this function may recognize additional locale-dependent syntax.
+-
+- If the string has valid syntax for a floating-point number but the
+- value is outside the range of a `double', `strtod' will signal
+- overflow or underflow as described in *Note Math Error Reporting::.
+-
+- `strtod' recognizes four special input strings. The strings
+- `"inf"' and `"infinity"' are converted to oo, or to the largest
+- representable value if the floating-point format doesn't support
+- infinities. You can prepend a `"+"' or `"-"' to specify the sign.
+- Case is ignored when scanning these strings.
+-
+- The strings `"nan"' and `"nan(CHARS...)"' are converted to NaN.
+- Again, case is ignored. If CHARS... are provided, they are used
+- in some unspecified fashion to select a particular representation
+- of NaN (there can be several).
+-
+- Since zero is a valid result as well as the value returned on
+- error, you should check for errors in the same way as for
+- `strtol', by examining ERRNO and TAILPTR.
+-
+- - Function: float strtof (const char *STRING, char **TAILPTR)
+- - Function: long double strtold (const char *STRING, char **TAILPTR)
+- These functions are analogous to `strtod', but return `float' and
+- `long double' values respectively. They report errors in the same
+- way as `strtod'. `strtof' can be substantially faster than
+- `strtod', but has less precision; conversely, `strtold' can be
+- much slower but has more precision (on systems where `long double'
+- is a separate type).
+-
+- These functions have been GNU extensions and are new to ISO C99.
+-
+- - Function: double wcstod (const wchar_t *restrict STRING, wchar_t
+- **restrict TAILPTR)
+- - Function: float wcstof (const wchar_t *STRING, wchar_t **TAILPTR)
+- - Function: long double wcstold (const wchar_t *STRING, wchar_t
+- **TAILPTR)
+- The `wcstod', `wcstof', and `wcstol' functions are equivalent in
+- nearly all aspect to the `strtod', `strtof', and `strtold'
+- functions but it handles wide character string.
+-
+- The `wcstod' function was introduced in Amendment 1 of ISO C90.
+- The `wcstof' and `wcstold' functions were introduced in ISO C99.
+-
+- - Function: double atof (const char *STRING)
+- This function is similar to the `strtod' function, except that it
+- need not detect overflow and underflow errors. The `atof' function
+- is provided mostly for compatibility with existing code; using
+- `strtod' is more robust.
+-
+- The GNU C library also provides `_l' versions of these functions,
+-which take an additional argument, the locale to use in conversion.

+-
+-Old-fashioned System V number-to-string functions
+-=================================================
+-
+- The old System V C library provided three functions to convert
+-numbers to strings, with unusual and hard-to-use semantics. The GNU C
+-library also provides these functions and some natural extensions.
+-
+- These functions are only available in glibc and on systems descended
+-from AT&T Unix. Therefore, unless these functions do precisely what you
+-need, it is better to use `sprintf', which is standard.
+-
+- All these functions are defined in `stdlib.h'.
+-
+- - Function: char * ecvt (double VALUE, int NDIGIT, int *DECPT, int
+- *NEG)
+- The function `ecvt' converts the floating-point number VALUE to a
+- string with at most NDIGIT decimal digits. The returned string
+- contains no decimal point or sign. The first digit of the string
+- is non-zero (unless VALUE is actually zero) and the last digit is
+- rounded to nearest. `*DECPT' is set to the index in the string of
+- the first digit after the decimal point. `*NEG' is set to a
+- nonzero value if VALUE is negative, zero otherwise.
+-
+- If NDIGIT decimal digits would exceed the precision of a `double'
+- it is reduced to a system-specific value.
+-
+- The returned string is statically allocated and overwritten by
+- each call to `ecvt'.
+-
+- If VALUE is zero, it is implementation defined whether `*DECPT' is
+- `0' or `1'.
+-
+- For example: `ecvt (12.3, 5, &d, &n)' returns `"12300"' and sets D
+- to `2' and N to `0'.
+-
+- - Function: char * fcvt (double VALUE, int NDIGIT, int *DECPT, int
+- *NEG)
+- The function `fcvt' is like `ecvt', but NDIGIT specifies the
+- number of digits after the decimal point. If NDIGIT is less than
+- zero, VALUE is rounded to the NDIGIT+1'th place to the left of the
+- decimal point. For example, if NDIGIT is `-1', VALUE will be
+- rounded to the nearest 10. If NDIGIT is negative and larger than
+- the number of digits to the left of the decimal point in VALUE,
+- VALUE will be rounded to one significant digit.
+-
+- If NDIGIT decimal digits would exceed the precision of a `double'
+- it is reduced to a system-specific value.
+-
+- The returned string is statically allocated and overwritten by
+- each call to `fcvt'.
+-
+- - Function: char * gcvt (double VALUE, int NDIGIT, char *BUF)
+- `gcvt' is functionally equivalent to `sprintf(buf, "%*g", ndigit,
+- value'. It is provided only for compatibility's sake. It returns
+- BUF.
+-
+- If NDIGIT decimal digits would exceed the precision of a `double'
+- it is reduced to a system-specific value.
+-
+- As extensions, the GNU C library provides versions of these three
+-functions that take `long double' arguments.
+-
+- - Function: char * qecvt (long double VALUE, int NDIGIT, int *DECPT,
+- int *NEG)
+- This function is equivalent to `ecvt' except that it takes a `long
+- double' for the first parameter and that NDIGIT is restricted by
+- the precision of a `long double'.
+-
+- - Function: char * qfcvt (long double VALUE, int NDIGIT, int *DECPT,
+- int *NEG)
+- This function is equivalent to `fcvt' except that it takes a `long
+- double' for the first parameter and that NDIGIT is restricted by
+- the precision of a `long double'.
+-
+- - Function: char * qgcvt (long double VALUE, int NDIGIT, char *BUF)
+- This function is equivalent to `gcvt' except that it takes a `long
+- double' for the first parameter and that NDIGIT is restricted by
+- the precision of a `long double'.
+-
+- The `ecvt' and `fcvt' functions, and their `long double'
+-equivalents, all return a string located in a static buffer which is
+-overwritten by the next call to the function. The GNU C library
+-provides another set of extended functions which write the converted
+-string into a user-supplied buffer. These have the conventional `_r'
+-suffix.
+-
+- `gcvt_r' is not necessary, because `gcvt' already uses a
+-user-supplied buffer.
+-
+- - Function: char * ecvt_r (double VALUE, int NDIGIT, int *DECPT, int
+- *NEG, char *BUF, size_t LEN)
+- The `ecvt_r' function is the same as `ecvt', except that it places
+- its result into the user-specified buffer pointed to by BUF, with
+- length LEN.
+-
+- This function is a GNU extension.
+-
+- - Function: char * fcvt_r (double VALUE, int NDIGIT, int *DECPT, int
+- *NEG, char *BUF, size_t LEN)
+- The `fcvt_r' function is the same as `fcvt', except that it places
+- its result into the user-specified buffer pointed to by BUF, with
+- length LEN.
+-
+- This function is a GNU extension.
+-
+- - Function: char * qecvt_r (long double VALUE, int NDIGIT, int *DECPT,
+- int *NEG, char *BUF, size_t LEN)
+- The `qecvt_r' function is the same as `qecvt', except that it
+- places its result into the user-specified buffer pointed to by
+- BUF, with length LEN.
+-
+- This function is a GNU extension.
+-
+- - Function: char * qfcvt_r (long double VALUE, int NDIGIT, int *DECPT,
+- int *NEG, char *BUF, size_t LEN)
+- The `qfcvt_r' function is the same as `qfcvt', except that it
+- places its result into the user-specified buffer pointed to by
+- BUF, with length LEN.
+-
+- This function is a GNU extension.

+-Time Basics
+-===========
+-
+- Discussing time in a technical manual can be difficult because the
+-word "time" in English refers to lots of different things. In this
+-manual, we use a rigorous terminology to avoid confusion, and the only
+-thing we use the simple word "time" for is to talk about the abstract
+-concept.
+-
+- A "calendar time" is a point in the time continuum, for example
+-November 4, 1990 at 18:02.5 UTC. Sometimes this is called "absolute
+-time".
+-
+- We don't speak of a "date", because that is inherent in a calendar
+-time.
+-
+- An "interval" is a contiguous part of the time continuum between two
+-calendar times, for example the hour between 9:00 and 10:00 on July 4,
+-1980.
+-
+- An "elapsed time" is the length of an interval, for example, 35
+-minutes. People sometimes sloppily use the word "interval" to refer to
+-the elapsed time of some interval.
+-
+- An "amount of time" is a sum of elapsed times, which need not be of
+-any specific intervals. For example, the amount of time it takes to
+-read a book might be 9 hours, independently of when and in how many
+-sittings it is read.
+-
+- A "period" is the elapsed time of an interval between two events,
+-especially when they are part of a sequence of regularly repeating
+-events.
+-
+- "CPU time" is like calendar time, except that it is based on the
+-subset of the time continuum when a particular process is actively
+-using a CPU. CPU time is, therefore, relative to a process.
+-
+- "Processor time" is an amount of time that a CPU is in use. In
+-fact, it's a basic system resource, since there's a limit to how much
+-can exist in any given interval (that limit is the elapsed time of the
+-interval times the number of CPUs in the processor). People often call
+-this CPU time, but we reserve the latter term in this manual for the
+-definition above.
+-

+-
+-Elapsed Time
+-============
+-
+- One way to represent an elapsed time is with a simple arithmetic data
+-type, as with the following function to compute the elapsed time between
+-two calendar times. This function is declared in `time.h'.
+-
+- - Function: double difftime (time_t TIME1, time_t TIME0)
+- The `difftime' function returns the number of seconds of elapsed
+- time between calendar time TIME1 and calendar time TIME0, as a
+- value of type `double'. The difference ignores leap seconds
+- unless leap second support is enabled.
+-
+- In the GNU system, you can simply subtract `time_t' values. But on
+- other systems, the `time_t' data type might use some other encoding
+- where subtraction doesn't work directly.
+-
+- The GNU C library provides two data types specifically for
+-representing an elapsed time. They are used by various GNU C library
+-functions, and you can use them for your own purposes too. They're
+-exactly the same except that one has a resolution in microseconds, and
+-the other, newer one, is in nanoseconds.
+-
+- - Data Type: struct timeval
+- The `struct timeval' structure represents an elapsed time. It is
+- declared in `sys/time.h' and has the following members:
+-
+- `long int tv_sec'
+- This represents the number of whole seconds of elapsed time.
+-
+- `long int tv_usec'
+- This is the rest of the elapsed time (a fraction of a second),
+- represented as the number of microseconds. It is always less
+- than one million.
+-
+-
+- - Data Type: struct timespec
+- The `struct timespec' structure represents an elapsed time. It is
+- declared in `time.h' and has the following members:
+-
+- `long int tv_sec'
+- This represents the number of whole seconds of elapsed time.
+-
+- `long int tv_nsec'
+- This is the rest of the elapsed time (a fraction of a second),
+- represented as the number of nanoseconds. It is always less
+- than one billion.
+-
+-
+- It is often necessary to subtract two values of type
+-`struct timeval' or `struct timespec'. Here is the best way to do
+-this. It works even on some peculiar operating systems where the
+-`tv_sec' member has an unsigned type.
+-
+- /* Subtract the `struct timeval' values X and Y,
+- storing the result in RESULT.
+- Return 1 if the difference is negative, otherwise 0. */
+-
+- int
+- timeval_subtract (result, x, y)
+- struct timeval *result, *x, *y;
+- {
+- /* Perform the carry for the later subtraction by updating Y. */
+- if (x->tv_usec < y->tv_usec) {
+- int nsec = (y->tv_usec - x->tv_usec) / 1000000 + 1;
+- y->tv_usec -= 1000000 * nsec;
+- y->tv_sec += nsec;
+- }
+- if (x->tv_usec - y->tv_usec > 1000000) {
+- int nsec = (x->tv_usec - y->tv_usec) / 1000000;
+- y->tv_usec += 1000000 * nsec;
+- y->tv_sec -= nsec;
+- }
+-
+- /* Compute the time remaining to wait.
+- `tv_usec' is certainly positive. */
+- result->tv_sec = x->tv_sec - y->tv_sec;
+- result->tv_usec = x->tv_usec - y->tv_usec;
+-
+- /* Return 1 if result is negative. */
+- return x->tv_sec < y->tv_sec;
+- }
+-
+- Common functions that use `struct timeval' are `gettimeofday' and
+-`settimeofday'.
+-
+- There are no GNU C library functions specifically oriented toward
+-dealing with elapsed times, but the calendar time, processor time, and
+-alarm and sleeping functions have a lot to do with them.

+-
+-Processor And CPU Time
+-======================
+-
+- If you're trying to optimize your program or measure its efficiency,
+-it's very useful to know how much processor time it uses. For that,
+-calendar time and elapsed times are useless because a process may spend
+-time waiting for I/O or for other processes to use the CPU. However,
+-you can get the information with the functions in this section.
+-
+- CPU time (*note Time Basics::) is represented by the data type
+-`clock_t', which is a number of "clock ticks". It gives the total
+-amount of time a process has actively used a CPU since some arbitrary
+-event. On the GNU system, that event is the creation of the process.
+-While arbitrary in general, the event is always the same event for any
+-particular process, so you can always measure how much time on the CPU
+-a particular computation takes by examinining the process' CPU time
+-before and after the computation.
+-
+- In the GNU system, `clock_t' is equivalent to `long int' and
+-`CLOCKS_PER_SEC' is an integer value. But in other systems, both
+-`clock_t' and the macro `CLOCKS_PER_SEC' can be either integer or
+-floating-point types. Casting CPU time values to `double', as in the
+-example above, makes sure that operations such as arithmetic and
+-printing work properly and consistently no matter what the underlying
+-representation is.
+-
+- Note that the clock can wrap around. On a 32bit system with
+-`CLOCKS_PER_SEC' set to one million this function will return the same
+-value approximately every 72 minutes.
+-
+- For additional functions to examine a process' use of processor time,

+-CPU Time Inquiry
+-----------------
+-
+- To get a process' CPU time, you can use the `clock' function. This
+-facility is declared in the header file `time.h'.
+-
+- In typical usage, you call the `clock' function at the beginning and
+-end of the interval you want to time, subtract the values, and then
+-divide by `CLOCKS_PER_SEC' (the number of clock ticks per second) to
+-get processor time, like this:
+-
+- #include <time.h>
+-
+- clock_t start, end;
+- double cpu_time_used;
+-
+- start = clock();
+- ... /* Do the work. */
+- end = clock();
+- cpu_time_used = ((double) (end - start)) / CLOCKS_PER_SEC;
+-
+- Do not use a single CPU time as an amount of time; it doesn't work
+-that way. Either do a subtraction as shown above or query processor
+-time directly. *Note Processor Time::.
+-
+- Different computers and operating systems vary wildly in how they
+-keep track of CPU time. It's common for the internal processor clock
+-to have a resolution somewhere between a hundredth and millionth of a
+-second.
+-
+- - Macro: int CLOCKS_PER_SEC
+- The value of this macro is the number of clock ticks per second
+- measured by the `clock' function. POSIX requires that this value
+- be one million independent of the actual resolution.
+-
+- - Macro: int CLK_TCK
+- This is an obsolete name for `CLOCKS_PER_SEC'.
+-
+- - Data Type: clock_t
+- This is the type of the value returned by the `clock' function.
+- Values of type `clock_t' are numbers of clock ticks.
+-
+- - Function: clock_t clock (void)
+- This function returns the calling process' current CPU time. If
+- the CPU time is not available or cannot be represented, `clock'
+- returns the value `(clock_t)(-1)'.

+-Processor Time Inquiry
+-----------------------
+-
+- The `times' function returns information about a process'

+-header file `sys/times.h' to use this facility.
+-
+- - Data Type: struct tms
+- The `tms' structure is used to return information about process
+- times. It contains at least the following members:
+-
+- `clock_t tms_utime'
+- This is the total processor time the calling process has used
+- in executing the instructions of its program.
+-
+- `clock_t tms_stime'
+- This is the processor time the system has used on behalf of
+- the calling process.
+-
+- `clock_t tms_cutime'
+- This is the sum of the `tms_utime' values and the `tms_cutime'
+- values of all terminated child processes of the calling
+- process, whose status has been reported to the parent process
+- by `wait' or `waitpid'; see *Note Process Completion::. In
+- other words, it represents the total processor time used in
+- executing the instructions of all the terminated child
+- processes of the calling process, excluding child processes
+- which have not yet been reported by `wait' or `waitpid'.
+-
+- `clock_t tms_cstime'
+- This is similar to `tms_cutime', but represents the total
+- processor time system has used on behalf of all the

+-
+- All of the times are given in numbers of clock ticks. Unlike CPU

+-Calendar Time
+-=============
+-
+- This section describes facilities for keeping track of calendar time.
+-*Note Time Basics::.
+-
+- The GNU C library represents calendar time three ways:
+-
+- * "Simple time" (the `time_t' data type) is a compact
+- representation, typically giving the number of seconds of elapsed
+- time since some implementation-specific base time.
+-
+- * There is also a "high-resolution time" representation. Like simple
+- time, this represents a calendar time as an elapsed time since a
+- base time, but instead of measuring in whole seconds, it uses a
+- `struct timeval' data type, which includes fractions of a second.
+- Use this time representation instead of simple time when you need
+- greater precision.
+-
+- * "Local time" or "broken-down time" (the `struct tm' data type)
+- represents a calendar time as a set of components specifying the
+- year, month, and so on in the Gregorian calendar, for a specific
+- time zone. This calendar time representation is usually used only
+- to communicate with people.

+-Simple Calendar Time
+---------------------
+-
+- This section describes the `time_t' data type for representing
+-calendar time as simple time, and the functions which operate on simple
+-time objects. These facilities are declared in the header file
+-`time.h'.
+-
+- - Data Type: time_t
+- This is the data type used to represent simple time. Sometimes,
+- it also represents an elapsed time. When interpreted as a
+- calendar time value, it represents the number of seconds elapsed
+- since 00:00:00 on January 1, 1970, Coordinated Universal Time.
+- (This calendar time is sometimes referred to as the "epoch".)
+- POSIX requires that this count not include leap seconds, but on
+- some systems this count includes leap seconds if you set `TZ' to
+- certain values (*note TZ Variable::).
+-
+- Note that a simple time has no concept of local time zone.
+- Calendar Time T is the same instant in time regardless of where on
+- the globe the computer is.
+-
+- In the GNU C library, `time_t' is equivalent to `long int'. In
+- other systems, `time_t' might be either an integer or
+- floating-point type.
+-
+- The function `difftime' tells you the elapsed time between two
+-simple calendar times, which is not always as easy to compute as just
+-subtracting. *Note Elapsed Time::.
+-
+- - Function: time_t time (time_t *RESULT)
+- The `time' function returns the current calendar time as a value of
+- type `time_t'. If the argument RESULT is not a null pointer, the
+- calendar time value is also stored in `*RESULT'. If the current
+- calendar time is not available, the value `(time_t)(-1)' is
+- returned.
+-
+- - Function: int stime (time_t *NEWTIME)
+- `stime' sets the system clock, i.e. it tells the system that the
+- current calendar time is NEWTIME, where `newtime' is interpreted
+- as described in the above definition of `time_t'.
+-
+- `settimeofday' is a newer function which sets the system clock to
+- better than one second precision. `settimeofday' is generally a
+- better choice than `stime'. *Note High-Resolution Calendar::.
+-
+- Only the superuser can set the system clock.
+-
+- If the function succeeds, the return value is zero. Otherwise, it
+- is `-1' and `errno' is set accordingly:
+-
+- `EPERM'
+- The process is not superuser.

+-
+-High-Resolution Calendar
+-------------------------
+-
+- The `time_t' data type used to represent simple times has a
+-resolution of only one second. Some applications need more precision.
+-
+- So, the GNU C library also contains functions which are capable of
+-representing calendar times to a higher resolution than one second. The
+-functions and the associated data types described in this section are
+-declared in `sys/time.h'.
+-
+- - Data Type: struct timezone
+- The `struct timezone' structure is used to hold minimal information
+- about the local time zone. It has the following members:
+-
+- `int tz_minuteswest'
+- This is the number of minutes west of UTC.
+-
+- `int tz_dsttime'
+- If nonzero, Daylight Saving Time applies during some part of
+- the year.
+-
+- The `struct timezone' type is obsolete and should never be used.
+- Instead, use the facilities described in *Note Time Zone
+- Functions::.
+-
+- - Function: int gettimeofday (struct timeval *TP, struct timezone *TZP)
+- The `gettimeofday' function returns the current calendar time as
+- the elapsed time since the epoch in the `struct timeval' structure
+- indicated by TP. (*note Elapsed Time:: for a description of
+- `struct timespec'). Information about the time zone is returned in
+- the structure pointed at TZP. If the TZP argument is a null
+- pointer, time zone information is ignored.
+-
+- The return value is `0' on success and `-1' on failure. The
+- following `errno' error condition is defined for this function:
+-
+- `ENOSYS'
+- The operating system does not support getting time zone
+- information, and TZP is not a null pointer. The GNU
+- operating system does not support using `struct timezone' to
+- represent time zone information; that is an obsolete feature
+- of 4.3 BSD. Instead, use the facilities described in *Note
+- Time Zone Functions::.
+-
+- - Function: int settimeofday (const struct timeval *TP, const struct
+- timezone *TZP)
+- The `settimeofday' function sets the current calendar time in the
+- system clock according to the arguments. As for `gettimeofday',
+- the calendar time is represented as the elapsed time since the
+- epoch. As for `gettimeofday', time zone information is ignored if
+- TZP is a null pointer.
+-
+- You must be a privileged user in order to use `settimeofday'.
+-
+- Some kernels automatically set the system clock from some source
+- such as a hardware clock when they start up. Others, including
+- Linux, place the system clock in an "invalid" state (in which
+- attempts to read the clock fail). A call of `stime' removes the
+- system clock from an invalid state, and system startup scripts
+- typically run a program that calls `stime'.
+-
+- `settimeofday' causes a sudden jump forwards or backwards, which
+- can cause a variety of problems in a system. Use `adjtime' (below)
+- to make a smooth transition from one time to another by temporarily
+- speeding up or slowing down the clock.
+-
+- With a Linux kernel, `adjtimex' does the same thing and can also
+- make permanent changes to the speed of the system clock so it
+- doesn't need to be corrected as often.
+-
+- The return value is `0' on success and `-1' on failure. The
+- following `errno' error conditions are defined for this function:
+-
+- `EPERM'
+- This process cannot set the clock because it is not
+- privileged.
+-
+- `ENOSYS'
+- The operating system does not support setting time zone
+- information, and TZP is not a null pointer.
+-
+- - Function: int adjtime (const struct timeval *DELTA, struct timeval
+- *OLDDELTA)
+- This function speeds up or slows down the system clock in order to
+- make a gradual adjustment. This ensures that the calendar time
+- reported by the system clock is always monotonically increasing,
+- which might not happen if you simply set the clock.
+-
+- The DELTA argument specifies a relative adjustment to be made to
+- the clock time. If negative, the system clock is slowed down for a
+- while until it has lost this much elapsed time. If positive, the
+- system clock is speeded up for a while.
+-
+- If the OLDDELTA argument is not a null pointer, the `adjtime'
+- function returns information about any previous time adjustment
+- that has not yet completed.
+-
+- This function is typically used to synchronize the clocks of
+- computers in a local network. You must be a privileged user to
+- use it.
+-
+- With a Linux kernel, you can use the `adjtimex' function to
+- permanently change the clock speed.
+-
+- The return value is `0' on success and `-1' on failure. The
+- following `errno' error condition is defined for this function:
+-
+- `EPERM'
+- You do not have privilege to set the time.
+-
+- *Portability Note:* The `gettimeofday', `settimeofday', and
+-`adjtime' functions are derived from BSD.
+-
+- Symbols for the following function are declared in `sys/timex.h'.
+-
+- - Function: int adjtimex (struct timex *TIMEX)
+- `adjtimex' is functionally identical to `ntp_adjtime'. *Note High
+- Accuracy Clock::.
+-
+- This function is present only with a Linux kernel.

+-
+-Broken-down Time
+-----------------
+-
+- Calendar time is represented by the usual GNU C library functions as
+-an elapsed time since a fixed base calendar time. This is convenient
+-for computation, but has no relation to the way people normally think of
+-calendar time. By contrast, "broken-down time" is a binary
+-representation of calendar time separated into year, month, day, and so
+-on. Broken-down time values are not useful for calculations, but they
+-are useful for printing human readable time information.
+-
+- A broken-down time value is always relative to a choice of time
+-zone, and it also indicates which time zone that is.
+-
+- The symbols in this section are declared in the header file `time.h'.
+-
+- - Data Type: struct tm
+- This is the data type used to represent a broken-down time. The
+- structure contains at least the following members, which can
+- appear in any order.
+-
+- `int tm_sec'
+- This is the number of full seconds since the top of the
+- minute (normally in the range `0' through `59', but the
+- actual upper limit is `60', to allow for leap seconds if leap
+- second support is available).
+-
+- `int tm_min'
+- This is the number of full minutes since the top of the hour
+- (in the range `0' through `59').
+-
+- `int tm_hour'
+- This is the number of full hours past midnight (in the range
+- `0' through `23').
+-
+- `int tm_mday'
+- This is the ordinal day of the month (in the range `1'
+- through `31'). Watch out for this one! As the only ordinal
+- number in the structure, it is inconsistent with the rest of
+- the structure.
+-
+- `int tm_mon'
+- This is the number of full calendar months since the
+- beginning of the year (in the range `0' through `11'). Watch
+- out for this one! People usually use ordinal numbers for
+- month-of-year (where January = 1).
+-
+- `int tm_year'
+- This is the number of full calendar years since 1900.
+-
+- `int tm_wday'
+- This is the number of full days since Sunday (in the range
+- `0' through `6').
+-
+- `int tm_yday'
+- This is the number of full days since the beginning of the
+- year (in the range `0' through `365').
+-
+- `int tm_isdst'
+- This is a flag that indicates whether Daylight Saving Time is
+- (or was, or will be) in effect at the time described. The
+- value is positive if Daylight Saving Time is in effect, zero
+- if it is not, and negative if the information is not
+- available.
+-
+- `long int tm_gmtoff'
+- This field describes the time zone that was used to compute
+- this broken-down time value, including any adjustment for
+- daylight saving; it is the number of seconds that you must
+- add to UTC to get local time. You can also think of this as
+- the number of seconds east of UTC. For example, for U.S.
+- Eastern Standard Time, the value is `-5*60*60'. The
+- `tm_gmtoff' field is derived from BSD and is a GNU library
+- extension; it is not visible in a strict ISO C environment.
+-
+- `const char *tm_zone'
+- This field is the name for the time zone that was used to
+- compute this broken-down time value. Like `tm_gmtoff', this
+- field is a BSD and GNU extension, and is not visible in a
+- strict ISO C environment.
+-
+- - Function: struct tm * localtime (const time_t *TIME)
+- The `localtime' function converts the simple time pointed to by
+- TIME to broken-down time representation, expressed relative to the
+- user's specified time zone.
+-
+- The return value is a pointer to a static broken-down time
+- structure, which might be overwritten by subsequent calls to
+- `ctime', `gmtime', or `localtime'. (But no other library function
+- overwrites the contents of this object.)
+-
+- The return value is the null pointer if TIME cannot be represented
+- as a broken-down time; typically this is because the year cannot
+- fit into an `int'.
+-
+- Calling `localtime' has one other effect: it sets the variable
+- `tzname' with information about the current time zone. *Note Time
+- Zone Functions::.
+-
+- Using the `localtime' function is a big problem in multi-threaded
+-programs. The result is returned in a static buffer and this is used in
+-all threads. POSIX.1c introduced a variant of this function.
+-
+- - Function: struct tm * localtime_r (const time_t *TIME, struct tm
+- *RESULTP)
+- The `localtime_r' function works just like the `localtime'
+- function. It takes a pointer to a variable containing a simple
+- time and converts it to the broken-down time format.
+-
+- But the result is not placed in a static buffer. Instead it is
+- placed in the object of type `struct tm' to which the parameter
+- RESULTP points.
+-
+- If the conversion is successful the function returns a pointer to
+- the object the result was written into, i.e., it returns RESULTP.
+-
+- - Function: struct tm * gmtime (const time_t *TIME)
+- This function is similar to `localtime', except that the
+- broken-down time is expressed as Coordinated Universal Time (UTC)
+- (formerly called Greenwich Mean Time (GMT)) rather than relative
+- to a local time zone.
+-
+-
+- As for the `localtime' function we have the problem that the result
+-is placed in a static variable. POSIX.1c also provides a replacement
+-for `gmtime'.
+-
+- - Function: struct tm * gmtime_r (const time_t *TIME, struct tm
+- *RESULTP)
+- This function is similar to `localtime_r', except that it converts
+- just like `gmtime' the given time as Coordinated Universal Time.
+-
+- If the conversion is successful the function returns a pointer to
+- the object the result was written into, i.e., it returns RESULTP.
+-
+- - Function: time_t mktime (struct tm *BROKENTIME)
+- The `mktime' function is used to convert a broken-down time
+- structure to a simple time representation. It also "normalizes"
+- the contents of the broken-down time structure, by filling in the
+- day of week and day of year based on the other date and time
+- components.
+-
+- The `mktime' function ignores the specified contents of the
+- `tm_wday' and `tm_yday' members of the broken-down time structure.
+- It uses the values of the other components to determine the
+- calendar time; it's permissible for these components to have
+- unnormalized values outside their normal ranges. The last thing
+- that `mktime' does is adjust the components of the BROKENTIME
+- structure (including the `tm_wday' and `tm_yday').
+-
+- If the specified broken-down time cannot be represented as a
+- simple time, `mktime' returns a value of `(time_t)(-1)' and does
+- not modify the contents of BROKENTIME.
+-
+- Calling `mktime' also sets the variable `tzname' with information
+- about the current time zone. *Note Time Zone Functions::.
+-
+- - Function: time_t timelocal (struct tm *BROKENTIME)
+- `timelocal' is functionally identical to `mktime', but more
+- mnemonically named. Note that it is the inverse of the `localtime'
+- function.
+-
+- *Portability note:* `mktime' is essentially universally
+- available. `timelocal' is rather rare.
+-
+-
+- - Function: time_t timegm (struct tm *BROKENTIME)
+- `timegm' is functionally identical to `mktime' except it always
+- takes the input values to be Coordinated Universal Time (UTC)
+- regardless of any local time zone setting.
+-
+- Note that `timegm' is the inverse of `gmtime'.
+-
+- *Portability note:* `mktime' is essentially universally
+- available. `timegm' is rather rare. For the most portable
+- conversion from a UTC broken-down time to a simple time, set the
+- `TZ' environment variable to UTC, call `mktime', then set `TZ'
+- back.

+-High Accuracy Clock
+--------------------
+-
+- The `ntp_gettime' and `ntp_adjtime' functions provide an interface
+-to monitor and manipulate the system clock to maintain high accuracy
+-time. For example, you can fine tune the speed of the clock or
+-synchronize it with another time source.
+-
+- A typical use of these functions is by a server implementing the
+-Network Time Protocol to synchronize the clocks of multiple systems and
+-high precision clocks.
+-
+- These functions are declared in `sys/timex.h'.
+-
+- - Data Type: struct ntptimeval
+- This structure is used for information about the system clock. It
+- contains the following members:
+- `struct timeval time'
+- This is the current calendar time, expressed as the elapsed
+- time since the epoch. The `struct timeval' data type is
+- described in *Note Elapsed Time::.
+-
+- `long int maxerror'
+- This is the maximum error, measured in microseconds. Unless
+- updated via `ntp_adjtime' periodically, this value will reach
+- some platform-specific maximum value.
+-
+- `long int esterror'
+- This is the estimated error, measured in microseconds. This
+- value can be set by `ntp_adjtime' to indicate the estimated
+- offset of the system clock from the true calendar time.
+-
+- - Function: int ntp_gettime (struct ntptimeval *TPTR)
+- The `ntp_gettime' function sets the structure pointed to by TPTR
+- to current values. The elements of the structure afterwards
+- contain the values the timer implementation in the kernel assumes.
+- They might or might not be correct. If they are not a
+- `ntp_adjtime' call is necessary.
+-
+- The return value is `0' on success and other values on failure.
+- The following `errno' error conditions are defined for this
+- function:
+-
+- `TIME_ERROR'
+- The precision clock model is not properly set up at the
+- moment, thus the clock must be considered unsynchronized, and
+- the values should be treated with care.
+-
+- - Data Type: struct timex
+- This structure is used to control and monitor the system clock. It
+- contains the following members:
+- `unsigned int modes'
+- This variable controls whether and which values are set.
+- Several symbolic constants have to be combined with _binary
+- or_ to specify the effective mode. These constants start
+- with `MOD_'.
+-
+- `long int offset'
+- This value indicates the current offset of the system clock
+- from the true calendar time. The value is given in
+- microseconds. If bit `MOD_OFFSET' is set in `modes', the
+- offset (and possibly other dependent values) can be set. The
+- offset's absolute value must not exceed `MAXPHASE'.
+-
+- `long int frequency'
+- This value indicates the difference in frequency between the
+- true calendar time and the system clock. The value is
+- expressed as scaled PPM (parts per million, 0.0001%). The
+- scaling is `1 << SHIFT_USEC'. The value can be set with bit
+- `MOD_FREQUENCY', but the absolute value must not exceed
+- `MAXFREQ'.
+-
+- `long int maxerror'
+- This is the maximum error, measured in microseconds. A new
+- value can be set using bit `MOD_MAXERROR'. Unless updated via
+- `ntp_adjtime' periodically, this value will increase steadily
+- and reach some platform-specific maximum value.
+-
+- `long int esterror'
+- This is the estimated error, measured in microseconds. This
+- value can be set using bit `MOD_ESTERROR'.
+-
+- `int status'
+- This variable reflects the various states of the clock
+- machinery. There are symbolic constants for the significant
+- bits, starting with `STA_'. Some of these flags can be
+- updated using the `MOD_STATUS' bit.
+-
+- `long int constant'
+- This value represents the bandwidth or stiffness of the PLL
+- (phase locked loop) implemented in the kernel. The value can
+- be changed using bit `MOD_TIMECONST'.
+-
+- `long int precision'
+- This value represents the accuracy or the maximum error when
+- reading the system clock. The value is expressed in
+- microseconds.
+-
+- `long int tolerance'
+- This value represents the maximum frequency error of the
+- system clock in scaled PPM. This value is used to increase
+- the `maxerror' every second.
+-
+- `struct timeval time'
+- The current calendar time.
+-
+- `long int tick'
+- The elapsed time between clock ticks in microseconds. A
+- clock tick is a periodic timer interrupt on which the system
+- clock is based.
+-
+- `long int ppsfreq'
+- This is the first of a few optional variables that are
+- present only if the system clock can use a PPS (pulse per
+- second) signal to discipline the system clock. The value is
+- expressed in scaled PPM and it denotes the difference in
+- frequency between the system clock and the PPS signal.
+-
+- `long int jitter'
+- This value expresses a median filtered average of the PPS
+- signal's dispersion in microseconds.
+-
+- `int shift'
+- This value is a binary exponent for the duration of the PPS
+- calibration interval, ranging from `PPS_SHIFT' to
+- `PPS_SHIFTMAX'.
+-
+- `long int stabil'
+- This value represents the median filtered dispersion of the
+- PPS frequency in scaled PPM.
+-
+- `long int jitcnt'
+- This counter represents the number of pulses where the jitter
+- exceeded the allowed maximum `MAXTIME'.
+-
+- `long int calcnt'
+- This counter reflects the number of successful calibration
+- intervals.
+-
+- `long int errcnt'
+- This counter represents the number of calibration errors
+- (caused by large offsets or jitter).
+-
+- `long int stbcnt'
+- This counter denotes the number of of calibrations where the
+- stability exceeded the threshold.
+-
+- - Function: int ntp_adjtime (struct timex *TPTR)
+- The `ntp_adjtime' function sets the structure specified by TPTR to
+- current values.
+-
+- In addition, `ntp_adjtime' updates some settings to match what you
+- pass to it in *TPTR. Use the `modes' element of *TPTR to select
+- what settings to update. You can set `offset', `freq',
+- `maxerror', `esterror', `status', `constant', and `tick'.
+-
+- `modes' = zero means set nothing.
+-
+- Only the superuser can update settings.
+-
+- The return value is `0' on success and other values on failure.
+- The following `errno' error conditions are defined for this
+- function:
+-
+- `TIME_ERROR'
+- The high accuracy clock model is not properly set up at the
+- moment, thus the clock must be considered unsynchronized, and
+- the values should be treated with care. Another reason could
+- be that the specified new values are not allowed.
+-
+- `EPERM'
+- The process specified a settings update, but is not superuser.
+-
+- For more details see RFC1305 (Network Time Protocol, Version 3) and
+- related documents.
+-
+- *Portability note:* Early versions of the GNU C library did not
+- have this function but did have the synonymous `adjtimex'.

+-Formatting Calendar Time
+-------------------------
+-
+- The functions described in this section format calendar time values
+-as strings. These functions are declared in the header file `time.h'.
+-
+- - Function: char * asctime (const struct tm *BROKENTIME)
+- The `asctime' function converts the broken-down time value that
+- BROKENTIME points to into a string in a standard format:
+-
+- "Tue May 21 13:46:22 1991\n"
+-
+- The abbreviations for the days of week are: `Sun', `Mon', `Tue',
+- `Wed', `Thu', `Fri', and `Sat'.
+-
+- The abbreviations for the months are: `Jan', `Feb', `Mar', `Apr',
+- `May', `Jun', `Jul', `Aug', `Sep', `Oct', `Nov', and `Dec'.
+-
+- The return value points to a statically allocated string, which
+- might be overwritten by subsequent calls to `asctime' or `ctime'.
+- (But no other library function overwrites the contents of this
+- string.)
+-
+- - Function: char * asctime_r (const struct tm *BROKENTIME, char
+- *BUFFER)
+- This function is similar to `asctime' but instead of placing the
+- result in a static buffer it writes the string in the buffer
+- pointed to by the parameter BUFFER. This buffer should have room
+- for at least 26 bytes, including the terminating null.
+-
+- If no error occurred the function returns a pointer to the string
+- the result was written into, i.e., it returns BUFFER. Otherwise
+- return `NULL'.
+-
+- - Function: char * ctime (const time_t *TIME)
+- The `ctime' function is similar to `asctime', except that you
+- specify the calendar time argument as a `time_t' simple time value
+- rather than in broken-down local time format. It is equivalent to
+-
+- asctime (localtime (TIME))
+-
+- `ctime' sets the variable `tzname', because `localtime' does so.
+- *Note Time Zone Functions::.
+-
+- - Function: char * ctime_r (const time_t *TIME, char *BUFFER)
+- This function is similar to `ctime', but places the result in the
+- string pointed to by BUFFER. It is equivalent to (written using
+- gcc extensions, *note Statement Exprs: (gcc)Statement Exprs.):
+-
+- ({ struct tm tm; asctime_r (localtime_r (time, &tm), buf); })
+-
+- If no error occurred the function returns a pointer to the string
+- the result was written into, i.e., it returns BUFFER. Otherwise
+- return `NULL'.
+-
+- - Function: size_t strftime (char *S, size_t SIZE, const char
+- *TEMPLATE, const struct tm *BROKENTIME)
+- This function is similar to the `sprintf' function (*note
+- Formatted Input::), but the conversion specifications that can
+- appear in the format template TEMPLATE are specialized for
+- printing components of the date and time BROKENTIME according to
+- the locale currently specified for time conversion (*note
+- Locales::).
+-
+- Ordinary characters appearing in the TEMPLATE are copied to the
+- output string S; this can include multibyte character sequences.
+- Conversion specifiers are introduced by a `%' character, followed
+- by an optional flag which can be one of the following. These flags
+- are all GNU extensions. The first three affect only the output of
+- numbers:
+-
+- `_'
+- The number is padded with spaces.
+-
+- `-'
+- The number is not padded at all.
+-
+- `0'
+- The number is padded with zeros even if the format specifies
+- padding with spaces.
+-
+- `^'
+- The output uses uppercase characters, but only if this is
+- possible (*note Case Conversion::).
+-
+- The default action is to pad the number with zeros to keep it a
+- constant width. Numbers that do not have a range indicated below
+- are never padded, since there is no natural width for them.
+-
+- Following the flag an optional specification of the width is
+- possible. This is specified in decimal notation. If the natural
+- size of the output is of the field has less than the specified
+- number of characters, the result is written right adjusted and
+- space padded to the given size.
+-
+- An optional modifier can follow the optional flag and width
+- specification. The modifiers, which were first standardized by
+- POSIX.2-1992 and by ISO C99, are:
+-
+- `E'
+- Use the locale's alternate representation for date and time.
+- This modifier applies to the `%c', `%C', `%x', `%X', `%y' and
+- `%Y' format specifiers. In a Japanese locale, for example,
+- `%Ex' might yield a date format based on the Japanese
+- Emperors' reigns.
+-
+- `O'
+- Use the locale's alternate numeric symbols for numbers. This
+- modifier applies only to numeric format specifiers.
+-
+- If the format supports the modifier but no alternate representation
+- is available, it is ignored.
+-
+- The conversion specifier ends with a format specifier taken from
+- the following list. The whole `%' sequence is replaced in the
+- output string as follows:
+-
+- `%a'
+- The abbreviated weekday name according to the current locale.
+-
+- `%A'
+- The full weekday name according to the current locale.
+-
+- `%b'
+- The abbreviated month name according to the current locale.
+-
+- `%B'
+- The full month name according to the current locale.
+-
+- `%c'
+- The preferred calendar time representation for the current
+- locale.
+-
+- `%C'
+- The century of the year. This is equivalent to the greatest
+- integer not greater than the year divided by 100.
+-
+- This format was first standardized by POSIX.2-1992 and by
+- ISO C99.
+-
+- `%d'
+- The day of the month as a decimal number (range `01' through
+- `31').
+-
+- `%D'
+- The date using the format `%m/%d/%y'.
+-
+- This format was first standardized by POSIX.2-1992 and by
+- ISO C99.
+-
+- `%e'
+- The day of the month like with `%d', but padded with blank
+- (range ` 1' through `31').
+-
+- This format was first standardized by POSIX.2-1992 and by
+- ISO C99.
+-
+- `%F'
+- The date using the format `%Y-%m-%d'. This is the form
+- specified in the ISO 8601 standard and is the preferred form
+- for all uses.
+-
+- This format was first standardized by ISO C99 and by
+- POSIX.1-2001.
+-
+- `%g'
+- The year corresponding to the ISO week number, but without
+- the century (range `00' through `99'). This has the same
+- format and value as `%y', except that if the ISO week number
+- (see `%V') belongs to the previous or next year, that year is
+- used instead.
+-
+- This format was first standardized by ISO C99 and by
+- POSIX.1-2001.
+-
+- `%G'
+- The year corresponding to the ISO week number. This has the
+- same format and value as `%Y', except that if the ISO week
+- number (see `%V') belongs to the previous or next year, that
+- year is used instead.
+-
+- This format was first standardized by ISO C99 and by
+- POSIX.1-2001 but was previously available as a GNU extension.
+-
+- `%h'
+- The abbreviated month name according to the current locale.
+- The action is the same as for `%b'.
+-
+- This format was first standardized by POSIX.2-1992 and by
+- ISO C99.
+-
+- `%H'
+- The hour as a decimal number, using a 24-hour clock (range
+- `00' through `23').
+-
+- `%I'
+- The hour as a decimal number, using a 12-hour clock (range
+- `01' through `12').
+-
+- `%j'
+- The day of the year as a decimal number (range `001' through
+- `366').
+-
+- `%k'
+- The hour as a decimal number, using a 24-hour clock like
+- `%H', but padded with blank (range ` 0' through `23').
+-
+- This format is a GNU extension.
+-
+- `%l'
+- The hour as a decimal number, using a 12-hour clock like
+- `%I', but padded with blank (range ` 1' through `12').
+-
+- This format is a GNU extension.
+-
+- `%m'
+- The month as a decimal number (range `01' through `12').
+-
+- `%M'
+- The minute as a decimal number (range `00' through `59').
+-
+- `%n'
+- A single `\n' (newline) character.
+-
+- This format was first standardized by POSIX.2-1992 and by
+- ISO C99.
+-
+- `%p'
+- Either `AM' or `PM', according to the given time value; or the
+- corresponding strings for the current locale. Noon is
+- treated as `PM' and midnight as `AM'. In most locales
+- `AM'/`PM' format is not supported, in such cases `"%p"'
+- yields an empty string.
+-
+- `%P'
+- Either `am' or `pm', according to the given time value; or the
+- corresponding strings for the current locale, printed in
+- lowercase characters. Noon is treated as `pm' and midnight
+- as `am'. In most locales `AM'/`PM' format is not supported,
+- in such cases `"%P"' yields an empty string.
+-
+- This format is a GNU extension.
+-
+- `%r'
+- The complete calendar time using the AM/PM format of the
+- current locale.
+-
+- This format was first standardized by POSIX.2-1992 and by
+- ISO C99. In the POSIX locale, this format is equivalent to
+- `%I:%M:%S %p'.
+-
+- `%R'
+- The hour and minute in decimal numbers using the format
+- `%H:%M'.
+-
+- This format was first standardized by ISO C99 and by
+- POSIX.1-2001 but was previously available as a GNU extension.
+-
+- `%s'
+- The number of seconds since the epoch, i.e., since 1970-01-01
+- 00:00:00 UTC. Leap seconds are not counted unless leap
+- second support is available.
+-
+- This format is a GNU extension.
+-
+- `%S'
+- The seconds as a decimal number (range `00' through `60').
+-
+- `%t'
+- A single `\t' (tabulator) character.
+-
+- This format was first standardized by POSIX.2-1992 and by
+- ISO C99.
+-
+- `%T'
+- The time of day using decimal numbers using the format
+- `%H:%M:%S'.
+-
+- This format was first standardized by POSIX.2-1992 and by
+- ISO C99.
+-
+- `%u'
+- The day of the week as a decimal number (range `1' through
+- `7'), Monday being `1'.
+-
+- This format was first standardized by POSIX.2-1992 and by
+- ISO C99.
+-
+- `%U'
+- The week number of the current year as a decimal number
+- (range `00' through `53'), starting with the first Sunday as
+- the first day of the first week. Days preceding the first
+- Sunday in the year are considered to be in week `00'.
+-
+- `%V'
+- The ISO 8601:1988 week number as a decimal number (range `01'
+- through `53'). ISO weeks start with Monday and end with
+- Sunday. Week `01' of a year is the first week which has the
+- majority of its days in that year; this is equivalent to the
+- week containing the year's first Thursday, and it is also
+- equivalent to the week containing January 4. Week `01' of a
+- year can contain days from the previous year. The week
+- before week `01' of a year is the last week (`52' or `53') of
+- the previous year even if it contains days from the new year.
+-
+- This format was first standardized by POSIX.2-1992 and by
+- ISO C99.
+-
+- `%w'
+- The day of the week as a decimal number (range `0' through
+- `6'), Sunday being `0'.
+-
+- `%W'
+- The week number of the current year as a decimal number
+- (range `00' through `53'), starting with the first Monday as
+- the first day of the first week. All days preceding the
+- first Monday in the year are considered to be in week `00'.
+-
+- `%x'
+- The preferred date representation for the current locale.
+-
+- `%X'
+- The preferred time of day representation for the current
+- locale.
+-
+- `%y'
+- The year without a century as a decimal number (range `00'
+- through `99'). This is equivalent to the year modulo 100.
+-
+- `%Y'
+- The year as a decimal number, using the Gregorian calendar.
+- Years before the year `1' are numbered `0', `-1', and so on.
+-
+- `%z'
+- RFC 822/ISO 8601:1988 style numeric time zone (e.g., `-0600'
+- or `+0100'), or nothing if no time zone is determinable.
+-
+- This format was first standardized by ISO C99 and by
+- POSIX.1-2001 but was previously available as a GNU extension.
+-
+- In the POSIX locale, a full RFC 822 timestamp is generated by
+- the format `"%a, %d %b %Y %H:%M:%S %z"' (or the equivalent
+- `"%a, %d %b %Y %T %z"').
+-
+- `%Z'
+- The time zone abbreviation (empty if the time zone can't be
+- determined).
+-
+- `%%'
+- A literal `%' character.
+-
+- The SIZE parameter can be used to specify the maximum number of
+- characters to be stored in the array S, including the terminating
+- null character. If the formatted time requires more than SIZE
+- characters, `strftime' returns zero and the contents of the array
+- S are undefined. Otherwise the return value indicates the number
+- of characters placed in the array S, not including the terminating
+- null character.
+-
+- _Warning:_ This convention for the return value which is prescribed
+- in ISO C can lead to problems in some situations. For certain
+- format strings and certain locales the output really can be the
+- empty string and this cannot be discovered by testing the return
+- value only. E.g., in most locales the AM/PM time format is not
+- supported (most of the world uses the 24 hour time
+- representation). In such locales `"%p"' will return the empty
+- string, i.e., the return value is zero. To detect situations like
+- this something similar to the following code should be used:
+-
+- buf[0] = '\1';
+- len = strftime (buf, bufsize, format, tp);
+- if (len == 0 && buf[0] != '\0')
+- {
+- /* Something went wrong in the strftime call. */
+- ...
+- }
+-
+- If S is a null pointer, `strftime' does not actually write
+- anything, but instead returns the number of characters it would
+- have written.
+-
+- According to POSIX.1 every call to `strftime' implies a call to
+- `tzset'. So the contents of the environment variable `TZ' is
+- examined before any output is produced.
+-
+- For an example of `strftime', see *Note Time Functions Example::.
+-
+- - Function: size_t wcsftime (wchar_t *S, size_t SIZE, const wchar_t
+- *TEMPLATE, const struct tm *BROKENTIME)
+- The `wcsftime' function is equivalent to the `strftime' function
+- with the difference that it operates on wide character strings.
+- The buffer where the result is stored, pointed to by S, must be an
+- array of wide characters. The parameter SIZE which specifies the
+- size of the output buffer gives the number of wide character, not
+- the number of bytes.
+-
+- Also the format string TEMPLATE is a wide character string. Since
+- all characters needed to specify the format string are in the basic
+- character set it is portably possible to write format strings in
+- the C source code using the `L"..."' notation. The parameter
+- BROKENTIME has the same meaning as in the `strftime' call.
+-
+- The `wcsftime' function supports the same flags, modifiers, and
+- format specifiers as the `strftime' function.
+-
+- The return value of `wcsftime' is the number of wide characters
+- stored in `s'. When more characters would have to be written than
+- can be placed in the buffer S the return value is zero, with the
+- same problems indicated in the `strftime' documentation.

+-Convert textual time and date information back
+-----------------------------------------------
+-
+- The ISO C standard does not specify any functions which can convert
+-the output of the `strftime' function back into a binary format. This
+-led to a variety of more-or-less successful implementations with
+-different interfaces over the years. Then the Unix standard was
+-extended by the addition of two functions: `strptime' and `getdate'.
+-Both have strange interfaces but at least they are widely available.

+- time strings.

+-File: libc.info, Node: Low-Level Time String Parsing, Next: General Time String Parsing, Up: Parsing Date and Time
+-
+-Interpret string according to given format
+-..........................................
+-
+- he first function is rather low-level. It is nevertheless frequently
+-used in software since it is better known. Its interface and
+-implementation are heavily influenced by the `getdate' function, which
+-is defined and implemented in terms of calls to `strptime'.
+-
+- - Function: char * strptime (const char *S, const char *FMT, struct tm
+- *TP)
+- The `strptime' function parses the input string S according to the
+- format string FMT and stores its results in the structure TP.
+-
+- The input string could be generated by a `strftime' call or
+- obtained any other way. It does not need to be in a
+- human-recognizable format; e.g. a date passed as `"02:1999:9"' is
+- acceptable, even though it is ambiguous without context. As long
+- as the format string FMT matches the input string the function
+- will succeed.
+-
+- The user has to make sure, though, that the input can be parsed in
+- a unambiguous way. The string `"1999112"' can be parsed using the
+- format `"%Y%m%d"' as 1999-1-12, 1999-11-2, or even 19991-1-2. It
+- is necessary to add appropriate separators to reliably get results.
+-
+- The format string consists of the same components as the format
+- string of the `strftime' function. The only difference is that
+- the flags `_', `-', `0', and `^' are not allowed. Several of the
+- distinct formats of `strftime' do the same work in `strptime'
+- since differences like case of the input do not matter. For
+- reasons of symmetry all formats are supported, though.
+-
+- The modifiers `E' and `O' are also allowed everywhere the
+- `strftime' function allows them.
+-
+- The formats are:
+-
+- `%a'
+- `%A'
+- The weekday name according to the current locale, in
+- abbreviated form or the full name.
+-
+- `%b'
+- `%B'
+- `%h'
+- The month name according to the current locale, in
+- abbreviated form or the full name.
+-
+- `%c'
+- The date and time representation for the current locale.
+-
+- `%Ec'
+- Like `%c' but the locale's alternative date and time format
+- is used.
+-
+- `%C'
+- The century of the year.
+-
+- It makes sense to use this format only if the format string
+- also contains the `%y' format.
+-
+- `%EC'
+- The locale's representation of the period.
+-
+- Unlike `%C' it sometimes makes sense to use this format since
+- some cultures represent years relative to the beginning of
+- eras instead of using the Gregorian years.
+-
+- `%d'
+-
+- `%e'
+- The day of the month as a decimal number (range `1' through
+- `31'). Leading zeroes are permitted but not required.
+-
+- `%Od'
+- `%Oe'
+- Same as `%d' but using the locale's alternative numeric
+- symbols.
+-
+- Leading zeroes are permitted but not required.
+-
+- `%D'
+- Equivalent to `%m/%d/%y'.
+-
+- `%F'
+- Equivalent to `%Y-%m-%d', which is the ISO 8601 date format.
+-
+- This is a GNU extension following an ISO C99 extension to
+- `strftime'.
+-
+- `%g'
+- The year corresponding to the ISO week number, but without
+- the century (range `00' through `99').
+-
+- _Note:_ Currently, this is not fully implemented. The format
+- is recognized, input is consumed but no field in TM is set.

+- `%p'
+-
+- `%P'
+- The locale-dependent equivalent to `AM' or `PM'.
+-
+- This format is not useful unless `%I' or `%l' is also used.
+- Another complication is that the locale might not define

+- The seconds as a decimal number (range `0' through `60').
+-
+- Leading zeroes are permitted but not required.
+-
+- *Note:* The Unix specification says the upper bound on this

+- used.
+-
+- `%y'
+- The year without a century as a decimal number (range `0'
+- through `99').
+-
+- Leading zeroes are permitted but not required.
+-
+- Note that it is questionable to use this format without the
+- `%C' format. The `strptime' function does regard input
+- values in the range 68 to 99 as the years 1969 to 1999 and
+- the values 0 to 68 as the years 2000 to 2068. But maybe this
+- heuristic fails for some input data.
+-
+- Therefore it is best to avoid `%y' completely and use `%Y'
+- instead.
+-
+- `%Ey'
+- The offset from `%EC' in the locale's alternative
+- representation.
+-
+- `%Oy'
+- The offset of the year (from `%C') using the locale's
+- alternative numeric symbols.
+-
+- `%Y'
+- The year as a decimal number, using the Gregorian calendar.
+-
+- `%EY'
+- The full alternative year representation.
+-
+- `%z'
+- The offset from GMT in ISO 8601/RFC822 format.
+-
+- `%Z'
+- The timezone name.
+-
+- _Note:_ Currently, this is not fully implemented. The format
+- is recognized, input is consumed but no field in TM is set.
+-
+- `%%'
+- A literal `%' character.
+-
+- All other characters in the format string must have a matching
+- character in the input string. Exceptions are white spaces in the
+- input string which can match zero or more whitespace characters in
+- the format string.
+-
+- *Portability Note:* The XPG standard advises applications to use
+- at least one whitespace character (as specified by `isspace') or
+- other non-alphanumeric characters between any two conversion
+- specifications. The GNU C Library does not have this limitation
+- but other libraries might have trouble parsing formats like
+- `"%d%m%Y%H%M%S"'.
+-
+- The `strptime' function processes the input string from right to
+- left. Each of the three possible input elements (white space,
+- literal, or format) are handled one after the other. If the input
+- cannot be matched to the format string the function stops. The
+- remainder of the format and input strings are not processed.
+-
+- The function returns a pointer to the first character it was
+- unable to process. If the input string contains more characters
+- than required by the format string the return value points right
+- after the last consumed input character. If the whole input
+- string is consumed the return value points to the `NULL' byte at
+- the end of the string. If an error occurs, i.e. `strptime' fails
+- to match all of the format string, the function returns `NULL'.
+-
+- The specification of the function in the XPG standard is rather
+-vague, leaving out a few important pieces of information. Most
+-importantly, it does not specify what happens to those elements of TM
+-which are not directly initialized by the different formats. The
+-implementations on different Unix systems vary here.
+-
+- The GNU libc implementation does not touch those fields which are not
+-directly initialized. Exceptions are the `tm_wday' and `tm_yday'
+-elements, which are recomputed if any of the year, month, or date
+-elements changed. This has two implications:
+-
+- * Before calling the `strptime' function for a new input string, you
+- should prepare the TM structure you pass. Normally this will mean
+- initializing all values are to zero. Alternatively, you can set
+- all fields to values like `INT_MAX', allowing you to determine
+- which elements were set by the function call. Zero does not work
+- here since it is a valid value for many of the fields.
+-
+- Careful initialization is necessary if you want to find out
+- whether a certain field in TM was initialized by the function call.
+-
+- * You can construct a `struct tm' value with several consecutive
+- `strptime' calls. A useful application of this is e.g. the parsing
+- of two separate strings, one containing date information and the
+- other time information. By parsing one after the other without
+- clearing the structure in-between, you can construct a complete
+- broken-down time.
+-
+- The following example shows a function which parses a string which is
+-contains the date information in either US style or ISO 8601 form:
+-
+- const char *
+- parse_date (const char *input, struct tm *tm)
+- {
+- const char *cp;
+-
+- /* First clear the result structure. */
+- memset (tm, '\0', sizeof (*tm));
+-
+- /* Try the ISO format first. */
+- cp = strptime (input, "%F", tm);
+- if (cp == NULL)
+- {
+- /* Does not match. Try the US form. */
+- cp = strptime (input, "%D", tm);
+- }
+-
+- return cp;
+- }

+-
+-A More User-friendly Way to Parse Times and Dates
+-.................................................
+-
+- The Unix standard defines another function for parsing date strings.
+-The interface is weird, but if the function happens to suit your
+-application it is just fine. It is problematic to use this function in
+-multi-threaded programs or libraries, since it returns a pointer to a
+-static variable, and uses a global variable and global state (an
+-environment variable).
+-
+- - Variable: getdate_err
+- This variable of type `int' contains the error code of the last
+- unsuccessful call to `getdate'. Defined values are:
+-
+- 1
+- The environment variable `DATEMSK' is not defined or null.
+-
+- 2
+- The template file denoted by the `DATEMSK' environment
+- variable cannot be opened.
+-
+- 3
+- Information about the template file cannot retrieved.
+-
+- 4
+- The template file is not a regular file.
+-
+- 5
+- An I/O error occurred while reading the template file.
+-
+- 6
+- Not enough memory available to execute the function.
+-
+- 7
+- The template file contains no matching template.
+-
+- 8
+- The input date is invalid, but would match a template
+- otherwise. This includes dates like February 31st, and dates
+- which cannot be represented in a `time_t' variable.
+-
+- - Function: struct tm * getdate (const char *STRING)
+- The interface to `getdate' is the simplest possible for a function
+- to parse a string and return the value. STRING is the input
+- string and the result is returned in a statically-allocated
+- variable.
+-
+- The details about how the string is processed are hidden from the
+- user. In fact, they can be outside the control of the program.
+- Which formats are recognized is controlled by the file named by
+- the environment variable `DATEMSK'. This file should contain
+- lines of valid format strings which could be passed to `strptime'.
+-
+- The `getdate' function reads these format strings one after the
+- other and tries to match the input string. The first line which
+- completely matches the input string is used.
+-
+- Elements not initialized through the format string retain the
+- values present at the time of the `getdate' function call.
+-
+- The formats recognized by `getdate' are the same as for
+- `strptime'. See above for an explanation. There are only a few
+- extensions to the `strptime' behavior:
+-
+- * If the `%Z' format is given the broken-down time is based on
+- the current time of the timezone matched, not of the current
+- timezone of the runtime environment.
+-
+- _Note_: This is not implemented (currently). The problem is
+- that timezone names are not unique. If a fixed timezone is
+- assumed for a given string (say `EST' meaning US East Coast
+- time), then uses for countries other than the USA will fail.
+- So far we have found no good solution to this.
+-
+- * If only the weekday is specified the selected day depends on
+- the current date. If the current weekday is greater or equal
+- to the `tm_wday' value the current week's day is chosen,
+- otherwise the day next week is chosen.
+-
+- * A similar heuristic is used when only the month is given and
+- not the year. If the month is greater than or equal to the
+- current month, then the current year is used. Otherwise it
+- wraps to next year. The first day of the month is assumed if
+- one is not explicitly specified.
+-
+- * The current hour, minute, and second are used if the
+- appropriate value is not set through the format.
+-
+- * If no date is given tomorrow's date is used if the time is
+- smaller than the current time. Otherwise today's date is
+- taken.
+-
+- It should be noted that the format in the template file need not
+- only contain format elements. The following is a list of possible
+- format strings (taken from the Unix standard):
+-
+- %m
+- %A %B %d, %Y %H:%M:%S
+- %A
+- %B
+- %m/%d/%y %I %p
+- %d,%m,%Y %H:%M
+- at %A the %dst of %B in %Y
+- run job at %I %p,%B %dnd
+- %A den %d. %B %Y %H.%M Uhr
+-
+- As you can see, the template list can contain very specific
+- strings like `run job at %I %p,%B %dnd'. Using the above list of
+- templates and assuming the current time is Mon Sep 22 12:19:47 EDT
+- 1986 we can obtain the following results for the given input.
+-
+- Input Match Result
+- Mon %a Mon Sep 22 12:19:47 EDT 1986
+- Sun %a Sun Sep 28 12:19:47 EDT 1986
+- Fri %a Fri Sep 26 12:19:47 EDT 1986
+- September %B Mon Sep 1 12:19:47 EDT 1986
+- January %B Thu Jan 1 12:19:47 EST 1987
+- December %B Mon Dec 1 12:19:47 EST 1986
+- Sep Mon %b %a Mon Sep 1 12:19:47 EDT 1986
+- Jan Fri %b %a Fri Jan 2 12:19:47 EST 1987
+- Dec Mon %b %a Mon Dec 1 12:19:47 EST 1986
+- Jan Wed 1989 %b %a %Y Wed Jan 4 12:19:47 EST 1989
+- Fri 9 %a %H Fri Sep 26 09:00:00 EDT 1986

+- 10:30 %H:%M Tue Sep 23 10:30:00 EDT 1986
+- 13:30 %H:%M Mon Sep 22 13:30:00 EDT 1986
+-
+- The return value of the function is a pointer to a static variable
+- of type `struct tm', or a null pointer if an error occurred. The
+- result is only valid until the next `getdate' call, making this
+- function unusable in multi-threaded applications.
+-
+- The `errno' variable is _not_ changed. Error conditions are
+- stored in the global variable `getdate_err'. See the description
+- above for a list of the possible error values.
+-
+- _Warning:_ The `getdate' function should _never_ be used in
+- SUID-programs. The reason is obvious: using the `DATEMSK'
+- environment variable you can get the function to open any
+- arbitrary file and chances are high that with some bogus input
+- (such as a binary file) the program will crash.
+-
+- - Function: int getdate_r (const char *STRING, struct tm *TP)
+- The `getdate_r' function is the reentrant counterpart of
+- `getdate'. It does not use the global variable `getdate_err' to
+- signal an error, but instead returns an error code. The same error
+- codes as described in the `getdate_err' documentation above are
+- used, with 0 meaning success.
+-
+- Moreover, `getdate_r' stores the broken-down time in the variable
+- of type `struct tm' pointed to by the second argument, rather than
+- in a static variable.
+-
+- This function is not defined in the Unix standard. Nevertheless
+- it is available on some other Unix systems as well.
+-
+- The warning against using `getdate' in SUID-programs applies to
+- `getdate_r' as well.

+-
+-Specifying the Time Zone with `TZ'
+-----------------------------------
+-
+- In POSIX systems, a user can specify the time zone by means of the
+-`TZ' environment variable. For information about how to set
+-environment variables, see *Note Environment Variables::. The functions
+-for accessing the time zone are declared in `time.h'.
+-
+- You should not normally need to set `TZ'. If the system is
+-configured properly, the default time zone will be correct. You might
+-set `TZ' if you are using a computer over a network from a different
+-time zone, and would like times reported to you in the time zone local
+-to you, rather than what is local to the computer.
+-
+- In POSIX.1 systems the value of the `TZ' variable can be in one of
+-three formats. With the GNU C library, the most common format is the
+-last one, which can specify a selection from a large database of time
+-zone information for many regions of the world. The first two formats
+-are used to describe the time zone information directly, which is both
+-more cumbersome and less precise. But the POSIX.1 standard only
+-specifies the details of the first two formats, so it is good to be
+-familiar with them in case you come across a POSIX.1 system that doesn't
+-support a time zone information database.
+-
+- The first format is used when there is no Daylight Saving Time (or
+-summer time) in the local time zone:
+-
+- STD OFFSET
+-
+- The STD string specifies the name of the time zone. It must be
+-three or more characters long and must not contain a leading colon,
+-embedded digits, commas, nor plus and minus signs. There is no space
+-character separating the time zone name from the OFFSET, so these
+-restrictions are necessary to parse the specification correctly.
+-
+- The OFFSET specifies the time value you must add to the local time
+-to get a Coordinated Universal Time value. It has syntax like
+-[`+'|`-']HH[`:'MM[`:'SS]]. This is positive if the local time zone is
+-west of the Prime Meridian and negative if it is east. The hour must
+-be between `0' and `23', and the minute and seconds between `0' and
+-`59'.
+-
+- For example, here is how we would specify Eastern Standard Time, but
+-without any Daylight Saving Time alternative:
+-
+- EST+5
+-
+- The second format is used when there is Daylight Saving Time:
+-
+- STD OFFSET DST [OFFSET]`,'START[`/'TIME]`,'END[`/'TIME]
+-
+- The initial STD and OFFSET specify the standard time zone, as
+-described above. The DST string and OFFSET specify the name and offset
+-for the corresponding Daylight Saving Time zone; if the OFFSET is
+-omitted, it defaults to one hour ahead of standard time.
+-
+- The remainder of the specification describes when Daylight Saving
+-Time is in effect. The START field is when Daylight Saving Time goes
+-into effect and the END field is when the change is made back to
+-standard time. The following formats are recognized for these fields:
+-
+-`JN'
+- This specifies the Julian day, with N between `1' and `365'.
+- February 29 is never counted, even in leap years.
+-
+-`N'
+- This specifies the Julian day, with N between `0' and `365'.
+- February 29 is counted in leap years.
+-
+-`MM.W.D'
+- This specifies day D of week W of month M. The day D must be
+- between `0' (Sunday) and `6'. The week W must be between `1' and
+- `5'; week `1' is the first week in which day D occurs, and week
+- `5' specifies the _last_ D day in the month. The month M should be
+- between `1' and `12'.
+-
+- The TIME fields specify when, in the local time currently in effect,
+-the change to the other time occurs. If omitted, the default is
+-`02:00:00'.
+-
+- For example, here is how you would specify the Eastern time zone in
+-the United States, including the appropriate Daylight Saving Time and
+-its dates of applicability. The normal offset from UTC is 5 hours;
+-since this is west of the prime meridian, the sign is positive. Summer
+-time begins on the first Sunday in April at 2:00am, and ends on the
+-last Sunday in October at 2:00am.
+-
+- EST+5EDT,M4.1.0/2,M10.5.0/2
+-
+- The schedule of Daylight Saving Time in any particular jurisdiction
+-has changed over the years. To be strictly correct, the conversion of
+-dates and times in the past should be based on the schedule that was in
+-effect then. However, this format has no facilities to let you specify
+-how the schedule has changed from year to year. The most you can do is
+-specify one particular schedule--usually the present day schedule--and
+-this is used to convert any date, no matter when. For precise time zone
+-specifications, it is best to use the time zone information database
+-(see below).
+-
+- The third format looks like this:
+-
+- :CHARACTERS
+-
+- Each operating system interprets this format differently; in the GNU
+-C library, CHARACTERS is the name of a file which describes the time
+-zone.
+-
+- If the `TZ' environment variable does not have a value, the
+-operation chooses a time zone by default. In the GNU C library, the
+-default time zone is like the specification `TZ=:/etc/localtime' (or
+-`TZ=:/usr/local/etc/localtime', depending on how GNU C library was
+-configured; *note Installation::). Other C libraries use their own
+-rule for choosing the default time zone, so there is little we can say
+-about them.
+-
+- If CHARACTERS begins with a slash, it is an absolute file name;
+-otherwise the library looks for the file
+-`/share/lib/zoneinfo/CHARACTERS'. The `zoneinfo' directory contains
+-data files describing local time zones in many different parts of the
+-world. The names represent major cities, with subdirectories for
+-geographical areas; for example, `America/New_York', `Europe/London',
+-`Asia/Hong_Kong'. These data files are installed by the system
+-administrator, who also sets `/etc/localtime' to point to the data file
+-for the local time zone. The GNU C library comes with a large database
+-of time zone information for most regions of the world, which is
+-maintained by a community of volunteers and put in the public domain.

+-
+-Functions and Variables for Time Zones
+---------------------------------------
+-
+- - Variable: char * tzname [2]
+- The array `tzname' contains two strings, which are the standard
+- names of the pair of time zones (standard and Daylight Saving)
+- that the user has selected. `tzname[0]' is the name of the
+- standard time zone (for example, `"EST"'), and `tzname[1]' is the
+- name for the time zone when Daylight Saving Time is in use (for
+- example, `"EDT"'). These correspond to the STD and DST strings
+- (respectively) from the `TZ' environment variable. If Daylight
+- Saving Time is never used, `tzname[1]' is the empty string.
+-
+- The `tzname' array is initialized from the `TZ' environment
+- variable whenever `tzset', `ctime', `strftime', `mktime', or
+- `localtime' is called. If multiple abbreviations have been used
+- (e.g. `"EWT"' and `"EDT"' for U.S. Eastern War Time and Eastern
+- Daylight Time), the array contains the most recent abbreviation.
+-
+- The `tzname' array is required for POSIX.1 compatibility, but in
+- GNU programs it is better to use the `tm_zone' member of the
+- broken-down time structure, since `tm_zone' reports the correct
+- abbreviation even when it is not the latest one.
+-
+- Though the strings are declared as `char *' the user must refrain
+- from modifying these strings. Modifying the strings will almost
+- certainly lead to trouble.
+-
+-
+- - Function: void tzset (void)
+- The `tzset' function initializes the `tzname' variable from the
+- value of the `TZ' environment variable. It is not usually
+- necessary for your program to call this function, because it is
+- called automatically when you use the other time conversion
+- functions that depend on the time zone.
+-
+- The following variables are defined for compatibility with System V
+-Unix. Like `tzname', these variables are set by calling `tzset' or the
+-other time conversion functions.
+-
+- - Variable: long int timezone
+- This contains the difference between UTC and the latest local
+- standard time, in seconds west of UTC. For example, in the U.S.
+- Eastern time zone, the value is `5*60*60'. Unlike the `tm_gmtoff'
+- member of the broken-down time structure, this value is not
+- adjusted for daylight saving, and its sign is reversed. In GNU
+- programs it is better to use `tm_gmtoff', since it contains the
+- correct offset even when it is not the latest one.
+-
+- - Variable: int daylight
+- This variable has a nonzero value if Daylight Saving Time rules
+- apply. A nonzero value does not necessarily mean that Daylight
+- Saving Time is now in effect; it means only that Daylight Saving
+- Time is sometimes in effect.

+-
+-Setting an Alarm
+-================
+-
+- The `alarm' and `setitimer' functions provide a mechanism for a
+-process to interrupt itself in the future. They do this by setting a
+-timer; when the timer expires, the process receives a signal.
+-
+- Each process has three independent interval timers available:
+-
+- * A real-time timer that counts elapsed time. This timer sends a
+- `SIGALRM' signal to the process when it expires.
+-
+- * A virtual timer that counts processor time used by the process.
+- This timer sends a `SIGVTALRM' signal to the process when it
+- expires.
+-
+- * A profiling timer that counts both processor time used by the
+- process, and processor time spent in system calls on behalf of the
+- process. This timer sends a `SIGPROF' signal to the process when
+- it expires.
+-
+- This timer is useful for profiling in interpreters. The interval
+- timer mechanism does not have the fine granularity necessary for
+- profiling native code.
+-
+- You can only have one timer of each kind set at any given time. If
+-you set a timer that has not yet expired, that timer is simply reset to
+-the new value.
+-
+- You should establish a handler for the appropriate alarm signal using
+-`signal' or `sigaction' before issuing a call to `setitimer' or
+-`alarm'. Otherwise, an unusual chain of events could cause the timer
+-to expire before your program establishes the handler. In this case it
+-would be terminated, since termination is the default action for the
+-alarm signals. *Note Signal Handling::.
+-
+- To be able to use the alarm function to interrupt a system call which
+-might block otherwise indefinitely it is important to _not_ set the
+-`SA_RESTART' flag when registering the signal handler using
+-`sigaction'. When not using `sigaction' things get even uglier: the
+-`signal' function has to fixed semantics with respect to restarts. The
+-BSD semantics for this function is to set the flag. Therefore, if
+-`sigaction' for whatever reason cannot be used, it is necessary to use
+-`sysv_signal' and not `signal'.
+-
+- The `setitimer' function is the primary means for setting an alarm.
+-This facility is declared in the header file `sys/time.h'. The `alarm'
+-function, declared in `unistd.h', provides a somewhat simpler interface
+-for setting the real-time timer.
+-
+- - Data Type: struct itimerval
+- This structure is used to specify when a timer should expire. It
+- contains the following members:
+- `struct timeval it_interval'
+- This is the period between successive timer interrupts. If
+- zero, the alarm will only be sent once.
+-
+- `struct timeval it_value'
+- This is the period between now and the first timer interrupt.
+- If zero, the alarm is disabled.
+-
+- The `struct timeval' data type is described in *Note Elapsed
+- Time::.
+-
+- - Function: int setitimer (int WHICH, struct itimerval *NEW, struct
+- itimerval *OLD)
+- The `setitimer' function sets the timer specified by WHICH
+- according to NEW. The WHICH argument can have a value of
+- `ITIMER_REAL', `ITIMER_VIRTUAL', or `ITIMER_PROF'.
+-
+- If OLD is not a null pointer, `setitimer' returns information
+- about any previous unexpired timer of the same kind in the
+- structure it points to.
+-
+- The return value is `0' on success and `-1' on failure. The
+- following `errno' error conditions are defined for this function:
+-
+- `EINVAL'
+- The timer period is too large.
+-
+- - Function: int getitimer (int WHICH, struct itimerval *OLD)
+- The `getitimer' function stores information about the timer
+- specified by WHICH in the structure pointed at by OLD.
+-
+- The return value and error conditions are the same as for
+- `setitimer'.
+-
+-`ITIMER_REAL'
+- This constant can be used as the WHICH argument to the `setitimer'
+- and `getitimer' functions to specify the real-time timer.
+-
+-`ITIMER_VIRTUAL'
+- This constant can be used as the WHICH argument to the `setitimer'
+- and `getitimer' functions to specify the virtual timer.
+-
+-`ITIMER_PROF'
+- This constant can be used as the WHICH argument to the `setitimer'
+- and `getitimer' functions to specify the profiling timer.
+-
+- - Function: unsigned int alarm (unsigned int SECONDS)
+- The `alarm' function sets the real-time timer to expire in SECONDS
+- seconds. If you want to cancel any existing alarm, you can do
+- this by calling `alarm' with a SECONDS argument of zero.
+-
+- The return value indicates how many seconds remain before the
+- previous alarm would have been sent. If there is no previous
+- alarm, `alarm' returns zero.
+-
+- The `alarm' function could be defined in terms of `setitimer' like
+-this:
+-
+- unsigned int
+- alarm (unsigned int seconds)
+- {
+- struct itimerval old, new;
+- new.it_interval.tv_usec = 0;
+- new.it_interval.tv_sec = 0;
+- new.it_value.tv_usec = 0;
+- new.it_value.tv_sec = (long int) seconds;
+- if (setitimer (ITIMER_REAL, &new, &old) < 0)
+- return 0;
+- else
+- return old.it_value.tv_sec;
+- }
+-
+- There is an example showing the use of the `alarm' function in *Note
+-Handler Returns::.
+-
+- If you simply want your process to wait for a given number of
+-seconds, you should use the `sleep' function. *Note Sleeping::.
+-
+- You shouldn't count on the signal arriving precisely when the timer
+-expires. In a multiprocessing environment there is typically some
+-amount of delay involved.
+-
+- *Portability Note:* The `setitimer' and `getitimer' functions are
+-derived from BSD Unix, while the `alarm' function is specified by the
+-POSIX.1 standard. `setitimer' is more powerful than `alarm', but
+-`alarm' is more widely used.

+-Sleeping
+-========
+-
+- The function `sleep' gives a simple way to make the program wait for
+-a short interval. If your program doesn't use signals (except to
+-terminate), then you can expect `sleep' to wait reliably throughout the
+-specified interval. Otherwise, `sleep' can return sooner if a signal
+-arrives; if you want to wait for a given interval regardless of
+-signals, use `select' (*note Waiting for I/O::) and don't specify any
+-descriptors to wait for.
+-
+- - Function: unsigned int sleep (unsigned int SECONDS)
+- The `sleep' function waits for SECONDS or until a signal is
+- delivered, whichever happens first.
+-
+- If `sleep' function returns because the requested interval is over,
+- it returns a value of zero. If it returns because of delivery of a
+- signal, its return value is the remaining time in the sleep
+- interval.
+-
+- The `sleep' function is declared in `unistd.h'.
+-
+- Resist the temptation to implement a sleep for a fixed amount of
+-time by using the return value of `sleep', when nonzero, to call
+-`sleep' again. This will work with a certain amount of accuracy as
+-long as signals arrive infrequently. But each signal can cause the
+-eventual wakeup time to be off by an additional second or so. Suppose a
+-few signals happen to arrive in rapid succession by bad luck--there is
+-no limit on how much this could shorten or lengthen the wait.
+-
+- Instead, compute the calendar time at which the program should stop
+-waiting, and keep trying to wait until that calendar time. This won't
+-be off by more than a second. With just a little more work, you can use
+-`select' and make the waiting period quite accurate. (Of course, heavy
+-system load can cause additional unavoidable delays--unless the machine
+-is dedicated to one application, there is no way you can avoid this.)
+-
+- On some systems, `sleep' can do strange things if your program uses
+-`SIGALRM' explicitly. Even if `SIGALRM' signals are being ignored or
+-blocked when `sleep' is called, `sleep' might return prematurely on
+-delivery of a `SIGALRM' signal. If you have established a handler for
+-`SIGALRM' signals and a `SIGALRM' signal is delivered while the process
+-is sleeping, the action taken might be just to cause `sleep' to return
+-instead of invoking your handler. And, if `sleep' is interrupted by
+-delivery of a signal whose handler requests an alarm or alters the
+-handling of `SIGALRM', this handler and `sleep' will interfere.
+-
+- On the GNU system, it is safe to use `sleep' and `SIGALRM' in the
+-same program, because `sleep' does not work by means of `SIGALRM'.
+-
+- - Function: int nanosleep (const struct timespec *REQUESTED_TIME,
+- struct timespec *REMAINING)
+- If resolution to seconds is not enough the `nanosleep' function can
+- be used. As the name suggests the sleep interval can be specified
+- in nanoseconds. The actual elapsed time of the sleep interval
+- might be longer since the system rounds the elapsed time you
+- request up to the next integer multiple of the actual resolution
+- the system can deliver.
+-
+- *`requested_time' is the elapsed time of the interval you want to
+- sleep.
+-
+- The function returns as *`remaining' the elapsed time left in the
+- interval for which you requested to sleep. If the interval
+- completed without getting interrupted by a signal, this is zero.
+-
+- `struct timespec' is described in *Note Elapsed Time::.
+-
+- If the function returns because the interval is over the return
+- value is zero. If the function returns -1 the global variable
+- ERRNO is set to the following values:
+-
+- `EINTR'
+- The call was interrupted because a signal was delivered to
+- the thread. If the REMAINING parameter is not the null
+- pointer the structure pointed to by REMAINING is updated to
+- contain the remaining elapsed time.
+-
+- `EINVAL'
+- The nanosecond value in the REQUESTED_TIME parameter contains
+- an illegal value. Either the value is negative or greater
+- than or equal to 1000 million.
+-
+- This function is a cancellation point in multi-threaded programs.
+- This is a problem if the thread allocates some resources (like
+- memory, file descriptors, semaphores or whatever) at the time
+- `nanosleep' is called. If the thread gets canceled these
+- resources stay allocated until the program ends. To avoid this
+- calls to `nanosleep' should be protected using cancellation
+- handlers.
+-
+- The `nanosleep' function is declared in `time.h'.

+-Resource Usage
+-==============
+-
+- The function `getrusage' and the data type `struct rusage' are used
+-to examine the resource usage of a process. They are declared in
+-`sys/resource.h'.
+-
+- - Function: int getrusage (int PROCESSES, struct rusage *RUSAGE)
+- This function reports resource usage totals for processes
+- specified by PROCESSES, storing the information in `*RUSAGE'.
+-
+- In most systems, PROCESSES has only two valid values:
+-
+- `RUSAGE_SELF'
+- Just the current process.
+-
+- `RUSAGE_CHILDREN'
+- All child processes (direct and indirect) that have already
+- terminated.
+-
+- In the GNU system, you can also inquire about a particular child
+- process by specifying its process ID.
+-
+- The return value of `getrusage' is zero for success, and `-1' for
+- failure.
+-
+- `EINVAL'
+- The argument PROCESSES is not valid.
+-
+- One way of getting resource usage for a particular child process is
+-with the function `wait4', which returns totals for a child when it
+-terminates. *Note BSD Wait Functions::.
+-
+- - Data Type: struct rusage
+- This data type stores various resource usage statistics. It has
+- the following members, and possibly others:
+-
+- `struct timeval ru_utime'
+- Time spent executing user instructions.
+-
+- `struct timeval ru_stime'
+- Time spent in operating system code on behalf of PROCESSES.
+-
+- `long int ru_maxrss'
+- The maximum resident set size used, in kilobytes. That is,
+- the maximum number of kilobytes of physical memory that
+- PROCESSES used simultaneously.
+-
+- `long int ru_ixrss'
+- An integral value expressed in kilobytes times ticks of
+- execution, which indicates the amount of memory used by text
+- that was shared with other processes.
+-
+- `long int ru_idrss'
+- An integral value expressed the same way, which is the amount
+- of unshared memory used for data.
+-
+- `long int ru_isrss'
+- An integral value expressed the same way, which is the amount
+- of unshared memory used for stack space.
+-
+- `long int ru_minflt'
+- The number of page faults which were serviced without
+- requiring any I/O.
+-
+- `long int ru_majflt'
+- The number of page faults which were serviced by doing I/O.
+-
+- `long int ru_nswap'
+- The number of times PROCESSES was swapped entirely out of
+- main memory.
+-
+- `long int ru_inblock'
+- The number of times the file system had to read from the disk
+- on behalf of PROCESSES.
+-
+- `long int ru_oublock'
+- The number of times the file system had to write to the disk
+- on behalf of PROCESSES.
+-
+- `long int ru_msgsnd'
+- Number of IPC messages sent.
+-
+- `long int ru_msgrcv'
+- Number of IPC messages received.
+-
+- `long int ru_nsignals'
+- Number of signals received.
+-
+- `long int ru_nvcsw'
+- The number of times PROCESSES voluntarily invoked a context
+- switch (usually to wait for some service).
+-
+- `long int ru_nivcsw'
+- The number of times an involuntary context switch took place
+- (because a time slice expired, or another process of higher
+- priority was scheduled).
+-
+- `vtimes' is a historical function that does some of what `getrusage'
+-does. `getrusage' is a better choice.
+-
+- `vtimes' and its `vtimes' data structure are declared in
+-`sys/vtimes.h'.
+-
+- - Function: int vtimes (struct vtimes CURRENT, struct vtimes CHILD)
+- `vtimes' reports resource usage totals for a process.
+-
+- If CURRENT is non-null, `vtimes' stores resource usage totals for
+- the invoking process alone in the structure to which it points. If
+- CHILD is non-null, `vtimes' stores resource usage totals for all
+- past children (which have terminated) of the invoking process in
+- the structure to which it points.
+-
+- - Data Type: struct vtimes
+- This data type contains information about the resource usage
+- of a process. Each member corresponds to a member of the
+- `struct rusage' data type described above.
+-
+- `vm_utime'
+- User CPU time. Analogous to `ru_utime' in `struct
+- rusage'
+-
+- `vm_stime'
+- System CPU time. Analogous to `ru_stime' in `struct
+- rusage'
+-
+- `vm_idsrss'
+- Data and stack memory. The sum of the values that would
+- be reported as `ru_idrss' and `ru_isrss' in `struct
+- rusage'
+-

+- Maximent resident set size. Analogous to `ru_maxrss' in
+- `struct rusage'
+-
+- `vm_majflt'
+- Major page faults. Analogous to `ru_majflt' in `struct
+- rusage'
+-
+- `vm_minflt'
+- Minor page faults. Analogous to `ru_minflt' in `struct
+- rusage'
+-
+- `vm_nswap'
+- Swap count. Analogous to `ru_nswap' in `struct rusage'
+-
+- `vm_inblk'
+- Disk reads. Analogous to `ru_inblk' in `struct rusage'
+-
+- `vm_oublk'
+- Disk writes. Analogous to `ru_oublk' in `struct rusage'
+-
+- The return value is zero if the function succeeds; `-1' otherwise.
+-
+- An additional historical function for examining resource usage,
+-`vtimes', is supported but not documented here. It is declared in

+-
+-Limiting Resource Usage
+-=======================
+-
+- You can specify limits for the resource usage of a process. When the
+-process tries to exceed a limit, it may get a signal, or the system call
+-by which it tried to do so may fail, depending on the resource. Each
+-process initially inherits its limit values from its parent, but it can
+-subsequently change them.
+-
+- There are two per-process limits associated with a resource:
+-
+-"current limit"
+- The current limit is the value the system will not allow usage to
+- exceed. It is also called the "soft limit" because the process
+- being limited can generally raise the current limit at will.
+-
+-"maximum limit"
+- The maximum limit is the maximum value to which a process is
+- allowed to set its current limit. It is also called the "hard
+- limit" because there is no way for a process to get around it. A
+- process may lower its own maximum limit, but only the superuser
+- may increase a maximum limit.
+-
+- The symbols for use with `getrlimit', `setrlimit', `getrlimit64',
+-and `setrlimit64' are defined in `sys/resource.h'.
+-
+- - Function: int getrlimit (int RESOURCE, struct rlimit *RLP)
+- Read the current and maximum limits for the resource RESOURCE and
+- store them in `*RLP'.
+-
+- The return value is `0' on success and `-1' on failure. The only
+- possible `errno' error condition is `EFAULT'.
+-
+- When the sources are compiled with `_FILE_OFFSET_BITS == 64' on a
+- 32-bit system this function is in fact `getrlimit64'. Thus, the
+- LFS interface transparently replaces the old interface.
+-
+- - Function: int getrlimit64 (int RESOURCE, struct rlimit64 *RLP)
+- This function is similar to `getrlimit' but its second parameter is
+- a pointer to a variable of type `struct rlimit64', which allows it
+- to read values which wouldn't fit in the member of a `struct
+- rlimit'.
+-
+- If the sources are compiled with `_FILE_OFFSET_BITS == 64' on a
+- 32-bit machine, this function is available under the name
+- `getrlimit' and so transparently replaces the old interface.
+-
+- - Function: int setrlimit (int RESOURCE, const struct rlimit *RLP)
+- Store the current and maximum limits for the resource RESOURCE in
+- `*RLP'.
+-
+- The return value is `0' on success and `-1' on failure. The
+- following `errno' error condition is possible:
+-
+- `EPERM'
+- * The process tried to raise a current limit beyond the
+- maximum limit.
+-
+- * The process tried to raise a maximum limit, but is not
+- superuser.
+-
+- When the sources are compiled with `_FILE_OFFSET_BITS == 64' on a
+- 32-bit system this function is in fact `setrlimit64'. Thus, the
+- LFS interface transparently replaces the old interface.
+-
+- - Function: int setrlimit64 (int RESOURCE, const struct rlimit64 *RLP)
+- This function is similar to `setrlimit' but its second parameter is
+- a pointer to a variable of type `struct rlimit64' which allows it
+- to set values which wouldn't fit in the member of a `struct
+- rlimit'.
+-
+- If the sources are compiled with `_FILE_OFFSET_BITS == 64' on a
+- 32-bit machine this function is available under the name
+- `setrlimit' and so transparently replaces the old interface.
+-
+- - Data Type: struct rlimit
+- This structure is used with `getrlimit' to receive limit values,
+- and with `setrlimit' to specify limit values for a particular
+- process and resource. It has two fields:
+-
+- `rlim_t rlim_cur'
+- The current limit
+-
+- `rlim_t rlim_max'
+- The maximum limit.
+-
+- For `getrlimit', the structure is an output; it receives the
+- current values. For `setrlimit', it specifies the new values.
+-
+- For the LFS functions a similar type is defined in `sys/resource.h'.
+-
+- - Data Type: struct rlimit64
+- This structure is analogous to the `rlimit' structure above, but
+- its components have wider ranges. It has two fields:
+-
+- `rlim64_t rlim_cur'
+- This is analogous to `rlimit.rlim_cur', but with a different
+- type.
+-
+- `rlim64_t rlim_max'
+- This is analogous to `rlimit.rlim_max', but with a different
+- type.
+-
+-
+- Here is a list of resources for which you can specify a limit.
+-Memory and file sizes are measured in bytes.
+-
+-`RLIMIT_CPU'
+- The maximum amount of CPU time the process can use. If it runs for
+- longer than this, it gets a signal: `SIGXCPU'. The value is
+- measured in seconds. *Note Operation Error Signals::.
+-
+-`RLIMIT_FSIZE'
+- The maximum size of file the process can create. Trying to write a
+- larger file causes a signal: `SIGXFSZ'. *Note Operation Error
+- Signals::.
+-
+-`RLIMIT_DATA'
+- The maximum size of data memory for the process. If the process
+- tries to allocate data memory beyond this amount, the allocation
+- function fails.
+-
+-`RLIMIT_STACK'
+- The maximum stack size for the process. If the process tries to
+- extend its stack past this size, it gets a `SIGSEGV' signal.
+- *Note Program Error Signals::.
+-
+-`RLIMIT_CORE'
+- The maximum size core file that this process can create. If the
+- process terminates and would dump a core file larger than this,
+- then no core file is created. So setting this limit to zero
+- prevents core files from ever being created.
+-
+-`RLIMIT_RSS'
+- The maximum amount of physical memory that this process should get.
+- This parameter is a guide for the system's scheduler and memory
+- allocator; the system may give the process more memory when there
+- is a surplus.
+-
+-`RLIMIT_MEMLOCK'
+- The maximum amount of memory that can be locked into physical
+- memory (so it will never be paged out).
+-
+-`RLIMIT_NPROC'
+- The maximum number of processes that can be created with the same
+- user ID. If you have reached the limit for your user ID, `fork'
+- will fail with `EAGAIN'. *Note Creating a Process::.
+-
+-`RLIMIT_NOFILE'
+-`RLIMIT_OFILE'
+- The maximum number of files that the process can open. If it
+- tries to open more files than this, its open attempt fails with
+- `errno' `EMFILE'. *Note Error Codes::. Not all systems support
+- this limit; GNU does, and 4.4 BSD does.
+-
+-`RLIMIT_AS'
+- The maximum size of total memory that this process should get. If
+- the process tries to allocate more memory beyond this amount with,
+- for example, `brk', `malloc', `mmap' or `sbrk', the allocation
+- function fails.
+-
+-`RLIM_NLIMITS'
+- The number of different resource limits. Any valid RESOURCE
+- operand must be less than `RLIM_NLIMITS'.
+-
+- - Constant: int RLIM_INFINITY
+- This constant stands for a value of "infinity" when supplied as
+- the limit value in `setrlimit'.
+-
+- The following are historical functions to do some of what the
+-functions above do. The functions above are better choices.
+-
+- `ulimit' and the command symbols are declared in `ulimit.h'.
+-
+- - Function: int ulimit (int CMD, ...)
+- `ulimit' gets the current limit or sets the current and maximum
+- limit for a particular resource for the calling process according
+- to the command CMD.a
+-
+- If you are getting a limit, the command argument is the only
+- argument. If you are setting a limit, there is a second argument:
+- `long int' LIMIT which is the value to which you are setting the
+- limit.
+-
+- The CMD values and the operations they specify are:
+- `GETFSIZE'
+- Get the current limit on the size of a file, in units of 512
+- bytes.
+-
+- `SETFSIZE'
+- Set the current and maximum limit on the size of a file to
+- LIMIT * 512 bytes.
+-
+- There are also some other CMD values that may do things on some
+- systems, but they are not supported.
+-
+- Only the superuser may increase a maximum limit.
+-
+- When you successfully get a limit, the return value of `ulimit' is
+- that limit, which is never negative. When you successfully set a
+- limit, the return value is zero. When the function fails, the
+- return value is `-1' and `errno' is set according to the reason:
+-
+- `EPERM'
+- A process tried to increase a maximum limit, but is not
+- superuser.
+-
+-
+- `vlimit' and its resource symbols are declared in `sys/vlimit.h'.
+-
+- - Function: int vlimit (int RESOURCE, int LIMIT)
+- `vlimit' sets the current limit for a resource for a process.
+-
+- RESOURCE identifies the resource:
+-
+- `LIM_CPU'
+- Maximum CPU time. Same as `RLIMIT_CPU' for `setrlimit'.
+-
+- `LIM_FSIZE'
+- Maximum file size. Same as `RLIMIT_FSIZE' for `setrlimit'.
+-
+- `LIM_DATA'
+- Maximum data memory. Same as `RLIMIT_DATA' for `setrlimit'.
+-
+- `LIM_STACK'
+- Maximum stack size. Same as `RLIMIT_STACK' for `setrlimit'.
+-
+- `LIM_CORE'
+- Maximum core file size. Same as `RLIMIT_COR' for `setrlimit'.
+-
+- `LIM_MAXRSS'
+- Maximum physical memory. Same as `RLIMIT_RSS' for
+- `setrlimit'.
+-
+- The return value is zero for success, and `-1' with `errno' set
+- accordingly for failure:
+-
+- `EPERM'
+- The process tried to set its current limit beyond its maximum
+- limit.

+-Process CPU Priority And Scheduling
+-===================================
+-
+- When multiple processes simultaneously require CPU time, the system's
+-scheduling policy and process CPU priorities determine which processes
+-get it. This section describes how that determination is made and GNU
+-C library functions to control it.
+-
+- It is common to refer to CPU scheduling simply as scheduling and a
+-process' CPU priority simply as the process' priority, with the CPU
+-resource being implied. Bear in mind, though, that CPU time is not the
+-only resource a process uses or that processes contend for. In some
+-cases, it is not even particularly important. Giving a process a high
+-"priority" may have very little effect on how fast a process runs with
+-respect to other processes. The priorities discussed in this section
+-apply only to CPU time.
+-
+- CPU scheduling is a complex issue and different systems do it in
+-wildly different ways. New ideas continually develop and find their
+-way into the intricacies of the various systems' scheduling algorithms.
+-This section discusses the general concepts, some specifics of systems
+-that commonly use the GNU C library, and some standards.
+-
+- For simplicity, we talk about CPU contention as if there is only one
+-CPU in the system. But all the same principles apply when a processor
+-has multiple CPUs, and knowing that the number of processes that can
+-run at any one time is equal to the number of CPUs, you can easily
+-extrapolate the information.
+-
+- The functions described in this section are all defined by the
+-POSIX.1 and POSIX.1b standards (the `sched...' functions are POSIX.1b).
+-However, POSIX does not define any semantics for the values that these
+-functions get and set. In this chapter, the semantics are based on the
+-Linux kernel's implementation of the POSIX standard. As you will see,
+-the Linux implementation is quite the inverse of what the authors of the
+-POSIX syntax had in mind.

+-
+-Absolute Priority
+------------------
+-
+- Every process has an absolute priority, and it is represented by a
+-number. The higher the number, the higher the absolute priority.
+-
+- On systems of the past, and most systems today, all processes have
+-absolute priority 0 and this section is irrelevant. In that case,
+-*Note Traditional Scheduling::. Absolute priorities were invented to
+-accommodate realtime systems, in which it is vital that certain
+-processes be able to respond to external events happening in real time,
+-which means they cannot wait around while some other process that _wants
+-to_, but doesn't _need to_ run occupies the CPU.
+-
+- When two processes are in contention to use the CPU at any instant,
+-the one with the higher absolute priority always gets it. This is true
+-even if the process with the lower priority is already using the CPU
+-(i.e. the scheduling is preemptive). Of course, we're only talking
+-about processes that are running or "ready to run," which means they are
+-ready to execute instructions right now. When a process blocks to wait
+-for something like I/O, its absolute priority is irrelevant.
+-
+- *Note:* The term "runnable" is a synonym for "ready to run."
+-
+- When two processes are running or ready to run and both have the same
+-absolute priority, it's more interesting. In that case, who gets the
+-CPU is determined by the scheduling policy. If the processes have
+-absolute priority 0, the traditional scheduling policy described in
+-*Note Traditional Scheduling:: applies. Otherwise, the policies
+-described in *Note Realtime Scheduling:: apply.
+-
+- You normally give an absolute priority above 0 only to a process that
+-can be trusted not to hog the CPU. Such processes are designed to block
+-(or terminate) after relatively short CPU runs.
+-
+- A process begins life with the same absolute priority as its parent
+-process. Functions described in *Note Basic Scheduling Functions:: can
+-change it.
+-
+- Only a privileged process can change a process' absolute priority to
+-something other than `0'. Only a privileged process or the target
+-process' owner can change its absolute priority at all.
+-
+- POSIX requires absolute priority values used with the realtime
+-scheduling policies to be consecutive with a range of at least 32. On
+-Linux, they are 1 through 99. The functions `sched_get_priority_max'
+-and `sched_set_priority_min' portably tell you what the range is on a
+-particular system.
+-
+-Using Absolute Priority
+-.......................
+-
+- One thing you must keep in mind when designing real time
+-applications is that having higher absolute priority than any other
+-process doesn't guarantee the process can run continuously. Two things
+-that can wreck a good CPU run are interrupts and page faults.
+-
+- Interrupt handlers live in that limbo between processes. The CPU is
+-executing instructions, but they aren't part of any process. An
+-interrupt will stop even the highest priority process. So you must
+-allow for slight delays and make sure that no device in the system has
+-an interrupt handler that could cause too long a delay between
+-instructions for your process.
+-
+- Similarly, a page fault causes what looks like a straightforward
+-sequence of instructions to take a long time. The fact that other
+-processes get to run while the page faults in is of no consequence,
+-because as soon as the I/O is complete, the high priority process will
+-kick them out and run again, but the wait for the I/O itself could be a
+-problem. To neutralize this threat, use `mlock' or `mlockall'.
+-
+- There are a few ramifications of the absoluteness of this priority
+-on a single-CPU system that you need to keep in mind when you choose to
+-set a priority and also when you're working on a program that runs with
+-high absolute priority. Consider a process that has higher absolute
+-priority than any other process in the system and due to a bug in its
+-program, it gets into an infinite loop. It will never cede the CPU.
+-You can't run a command to kill it because your command would need to
+-get the CPU in order to run. The errant program is in complete
+-control. It controls the vertical, it controls the horizontal.
+-
+- There are two ways to avoid this: 1) keep a shell running somewhere
+-with a higher absolute priority. 2) keep a controlling terminal
+-attached to the high priority process group. All the priority in the
+-world won't stop an interrupt handler from running and delivering a
+-signal to the process if you hit Control-C.
+-
+- Some systems use absolute priority as a means of allocating a fixed
+-percentage of CPU time to a process. To do this, a super high priority
+-privileged process constantly monitors the process' CPU usage and raises
+-its absolute priority when the process isn't getting its entitled share
+-and lowers it when the process is exceeding it.
+-
+- *Note:* The absolute priority is sometimes called the "static
+-priority." We don't use that term in this manual because it misses the
+-most important feature of the absolute priority: its absoluteness.

+-
+-Realtime Scheduling
+--------------------
+-
+- Whenever two processes with the same absolute priority are ready to
+-run, the kernel has a decision to make, because only one can run at a
+-time. If the processes have absolute priority 0, the kernel makes this
+-decision as described in *Note Traditional Scheduling::. Otherwise,
+-the decision is as described in this section.
+-
+- If two processes are ready to run but have different absolute
+-priorities, the decision is much simpler, and is described in *Note
+-Absolute Priority::.
+-
+- Each process has a scheduling policy. For processes with absolute
+-priority other than zero, there are two available:
+-
+- 1. First Come First Served
+-
+- 2. Round Robin
+-
+- The most sensible case is where all the processes with a certain
+-absolute priority have the same scheduling policy. We'll discuss that
+-first.
+-
+- In Round Robin, processes share the CPU, each one running for a small
+-quantum of time ("time slice") and then yielding to another in a
+-circular fashion. Of course, only processes that are ready to run and
+-have the same absolute priority are in this circle.
+-
+- In First Come First Served, the process that has been waiting the
+-longest to run gets the CPU, and it keeps it until it voluntarily
+-relinquishes the CPU, runs out of things to do (blocks), or gets
+-preempted by a higher priority process.
+-
+- First Come First Served, along with maximal absolute priority and
+-careful control of interrupts and page faults, is the one to use when a
+-process absolutely, positively has to run at full CPU speed or not at
+-all.
+-
+- Judicious use of `sched_yield' function invocations by processes
+-with First Come First Served scheduling policy forms a good compromise
+-between Round Robin and First Come First Served.
+-
+- To understand how scheduling works when processes of different
+-scheduling policies occupy the same absolute priority, you have to know
+-the nitty gritty details of how processes enter and exit the ready to
+-run list:
+-
+- In both cases, the ready to run list is organized as a true queue,
+-where a process gets pushed onto the tail when it becomes ready to run
+-and is popped off the head when the scheduler decides to run it. Note
+-that ready to run and running are two mutually exclusive states. When
+-the scheduler runs a process, that process is no longer ready to run
+-and no longer in the ready to run list. When the process stops
+-running, it may go back to being ready to run again.
+-
+- The only difference between a process that is assigned the Round
+-Robin scheduling policy and a process that is assigned First Come First
+-Serve is that in the former case, the process is automatically booted
+-off the CPU after a certain amount of time. When that happens, the
+-process goes back to being ready to run, which means it enters the
+-queue at the tail. The time quantum we're talking about is small.
+-Really small. This is not your father's timesharing. For example,
+-with the Linux kernel, the round robin time slice is a thousand times
+-shorter than its typical time slice for traditional scheduling.
+-
+- A process begins life with the same scheduling policy as its parent
+-process. Functions described in *Note Basic Scheduling Functions:: can
+-change it.
+-
+- Only a privileged process can set the scheduling policy of a process
+-that has absolute priority higher than 0.

+-Basic Scheduling Functions
+---------------------------
+-
+- This section describes functions in the GNU C library for setting the
+-absolute priority and scheduling policy of a process.
+-
+- *Portability Note:* On systems that have the functions in this
+-section, the macro _POSIX_PRIORITY_SCHEDULING is defined in
+-`<unistd.h>'.
+-
+- For the case that the scheduling policy is traditional scheduling,
+-more functions to fine tune the scheduling are in *Note Traditional
+-Scheduling::.
+-
+- Don't try to make too much out of the naming and structure of these
+-functions. They don't match the concepts described in this manual
+-because the functions are as defined by POSIX.1b, but the implementation
+-on systems that use the GNU C library is the inverse of what the POSIX
+-structure contemplates. The POSIX scheme assumes that the primary
+-scheduling parameter is the scheduling policy and that the priority
+-value, if any, is a parameter of the scheduling policy. In the
+-implementation, though, the priority value is king and the scheduling
+-policy, if anything, only fine tunes the effect of that priority.
+-
+- The symbols in this section are declared by including file `sched.h'.
+-
+- - Data Type: struct sched_param
+- This structure describes an absolute priority.
+- `int sched_priority'
+- absolute priority value
+-
+- - Function: int sched_setscheduler (pid_t PID, int POLICY, const
+- struct sched_param *PARAM)
+- This function sets both the absolute priority and the scheduling
+- policy for a process.
+-
+- It assigns the absolute priority value given by PARAM and the
+- scheduling policy POLICY to the process with Process ID PID, or
+- the calling process if PID is zero. If POLICY is negative,
+- `sched_setscheduler' keeps the existing scheduling policy.
+-
+- The following macros represent the valid values for POLICY:
+-
+- `SCHED_OTHER'
+- Traditional Scheduling
+-
+- `SCHED_FIFO'
+- First In First Out
+-
+- `SCHED_RR'
+- Round Robin
+-
+- On success, the return value is `0'. Otherwise, it is `-1' and
+- `ERRNO' is set accordingly. The `errno' values specific to this
+- function are:
+-
+- `EPERM'
+- * The calling process does not have `CAP_SYS_NICE'
+- permission and POLICY is not `SCHED_OTHER' (or it's
+- negative and the existing policy is not `SCHED_OTHER'.
+-
+- * The calling process does not have `CAP_SYS_NICE'
+- permission and its owner is not the target process'
+- owner. I.e. the effective uid of the calling process
+- is neither the effective nor the real uid of process PID.
+-
+- `ESRCH'
+- There is no process with pid PID and PID is not zero.
+-
+- `EINVAL'
+- * POLICY does not identify an existing scheduling policy.
+-
+- * The absolute priority value identified by *PARAM is
+- outside the valid range for the scheduling policy POLICY
+- (or the existing scheduling policy if POLICY is
+- negative) or PARAM is null. `sched_get_priority_max'
+- and `sched_get_priority_min' tell you what the valid
+- range is.
+-
+- * PID is negative.
+-
+-
+- - Function: int sched_getscheduler (pid_t PID)
+- This function returns the scheduling policy assigned to the
+- process with Process ID (pid) PID, or the calling process if PID
+- is zero.
+-
+- The return value is the scheduling policy. See
+- `sched_setscheduler' for the possible values.
+-
+- If the function fails, the return value is instead `-1' and
+- `errno' is set accordingly.
+-
+- The `errno' values specific to this function are:
+-
+- `ESRCH'
+- There is no process with pid PID and it is not zero.
+-
+- `EINVAL'
+- PID is negative.
+-
+- Note that this function is not an exact mate to
+- `sched_setscheduler' because while that function sets the
+- scheduling policy and the absolute priority, this function gets
+- only the scheduling policy. To get the absolute priority, use
+- `sched_getparam'.
+-
+-
+- - Function: int sched_setparam (pid_t PID, const struct sched_param
+- *PARAM)
+- This function sets a process' absolute priority.
+-
+- It is functionally identical to `sched_setscheduler' with POLICY =
+- `-1'.
+-
+-
+- - Function: int sched_getparam (pid_t PID, const struct sched_param
+- *PARAM)
+- This function returns a process' absolute priority.
+-
+- PID is the Process ID (pid) of the process whose absolute priority
+- you want to know.
+-
+- PARAM is a pointer to a structure in which the function stores the
+- absolute priority of the process.
+-
+- On success, the return value is `0'. Otherwise, it is `-1' and
+- `ERRNO' is set accordingly. The `errno' values specific to this
+- function are:
+-
+- `ESRCH'
+- There is no process with pid PID and it is not zero.
+-
+- `EINVAL'
+- PID is negative.
+-
+-
+- - Function: int sched_get_priority_min (int *POLICY);
+- This function returns the lowest absolute priority value that is
+- allowable for a process with scheduling policy POLICY.
+-
+- On Linux, it is 0 for SCHED_OTHER and 1 for everything else.
+-
+- On success, the return value is `0'. Otherwise, it is `-1' and
+- `ERRNO' is set accordingly. The `errno' values specific to this
+- function are:
+-
+- `EINVAL'
+- POLICY does not identify an existing scheduling policy.
+-
+-
+- - Function: int sched_get_priority_max (int *POLICY);
+- This function returns the highest absolute priority value that is
+- allowable for a process that with scheduling policy POLICY.
+-
+- On Linux, it is 0 for SCHED_OTHER and 99 for everything else.
+-
+- On success, the return value is `0'. Otherwise, it is `-1' and
+- `ERRNO' is set accordingly. The `errno' values specific to this
+- function are:
+-
+- `EINVAL'
+- POLICY does not identify an existing scheduling policy.
+-
+-
+- - Function: int sched_rr_get_interval (pid_t PID, struct timespec
+- *INTERVAL)
+- This function returns the length of the quantum (time slice) used
+- with the Round Robin scheduling policy, if it is used, for the
+- process with Process ID PID.
+-
+- It returns the length of time as INTERVAL.
+-
+- With a Linux kernel, the round robin time slice is always 150
+- microseconds, and PID need not even be a real pid.
+-
+- The return value is `0' on success and in the pathological case
+- that it fails, the return value is `-1' and `errno' is set
+- accordingly. There is nothing specific that can go wrong with this
+- function, so there are no specific `errno' values.
+-
+-
+- - Function: int sched_yield (void)
+- This function voluntarily gives up the process' claim on the CPU.
+-
+- Technically, `sched_yield' causes the calling process to be made
+- immediately ready to run (as opposed to running, which is what it
+- was before). This means that if it has absolute priority higher
+- than 0, it gets pushed onto the tail of the queue of processes
+- that share its absolute priority and are ready to run, and it will
+- run again when its turn next arrives. If its absolute priority is
+- 0, it is more complicated, but still has the effect of yielding
+- the CPU to other processes.
+-
+- If there are no other processes that share the calling process'
+- absolute priority, this function doesn't have any effect.
+-
+- To the extent that the containing program is oblivious to what
+- other processes in the system are doing and how fast it executes,
+- this function appears as a no-op.
+-
+- The return value is `0' on success and in the pathological case
+- that it fails, the return value is `-1' and `errno' is set
+- accordingly. There is nothing specific that can go wrong with this
+- function, so there are no specific `errno' values.

+-----------------------
+-
+- This section is about the scheduling among processes whose absolute

+-are left over after the processes with higher absolute priority have
+-taken all they want, the scheduling described herein determines who
+-among the great unwashed processes gets them.

+-Introduction To Traditional Scheduling
+-......................................
+-
+- Long before there was absolute priority (See *Note Absolute
+-Priority::), Unix systems were scheduling the CPU using this system.
+-When Posix came in like the Romans and imposed absolute priorities to
+-accommodate the needs of realtime processing, it left the indigenous
+-Absolute Priority Zero processes to govern themselves by their own
+-familiar scheduling policy.
+-
+- Indeed, absolute priorities higher than zero are not available on
+-many systems today and are not typically used when they are, being
+-intended mainly for computers that do realtime processing. So this
+-section describes the only scheduling many programmers need to be
+-concerned about.
+-
+- But just to be clear about the scope of this scheduling: Any time a
+-process with a absolute priority of 0 and a process with an absolute
+-priority higher than 0 are ready to run at the same time, the one with
+-absolute priority 0 does not run. If it's already running when the
+-higher priority ready-to-run process comes into existence, it stops
+-immediately.
+-
+- In addition to its absolute priority of zero, every process has
+-another priority, which we will refer to as "dynamic priority" because
+-it changes over time. The dynamic priority is meaningless for
+-processes with an absolute priority higher than zero.
+-
+- The dynamic priority sometimes determines who gets the next turn on
+-the CPU. Sometimes it determines how long turns last. Sometimes it
+-determines whether a process can kick another off the CPU.
+-
+- In Linux, the value is a combination of these things, but mostly it
+-is just determines the length of the time slice. The higher a process'
+-dynamic priority, the longer a shot it gets on the CPU when it gets one.
+-If it doesn't use up its time slice before giving up the CPU to do
+-something like wait for I/O, it is favored for getting the CPU back when
+-it's ready for it, to finish out its time slice. Other than that,
+-selection of processes for new time slices is basically round robin.
+-But the scheduler does throw a bone to the low priority processes: A
+-process' dynamic priority rises every time it is snubbed in the
+-scheduling process. In Linux, even the fat kid gets to play.
+-
+- The fluctuation of a process' dynamic priority is regulated by
+-another value: The "nice" value. The nice value is an integer, usually
+-in the range -20 to 20, and represents an upper limit on a process'
+-dynamic priority. The higher the nice number, the lower that limit.
+-
+- On a typical Linux system, for example, a process with a nice value
+-of 20 can get only 10 milliseconds on the CPU at a time, whereas a
+-process with a nice value of -20 can achieve a high enough priority to
+-get 400 milliseconds.
+-
+- The idea of the nice value is deferential courtesy. In the
+-beginning, in the Unix garden of Eden, all processes shared equally in
+-the bounty of the computer system. But not all processes really need
+-the same share of CPU time, so the nice value gave a courteous process
+-the ability to refuse its equal share of CPU time that others might
+-prosper. Hence, the higher a process' nice value, the nicer the
+-process is. (Then a snake came along and offered some process a
+-negative nice value and the system became the crass resource allocation
+-system we know today).
+-
+- Dynamic priorities tend upward and downward with an objective of
+-smoothing out allocation of CPU time and giving quick response time to
+-infrequent requests. But they never exceed their nice limits, so on a
+-heavily loaded CPU, the nice value effectively determines how fast a
+-process runs.
+-
+- In keeping with the socialistic heritage of Unix process priority, a
+-process begins life with the same nice value as its parent process and
+-can raise it at will. A process can also raise the nice value of any
+-other process owned by the same user (or effective user). But only a
+-privileged process can lower its nice value. A privileged process can
+-also raise or lower another process' nice value.
+-
+- GNU C Library functions for getting and setting nice values are
+-described in *Note Traditional Scheduling Functions::.

+-Functions For Traditional Scheduling
+-....................................
+-
+- This section describes how you can read and set the nice value of a
+-process. All these symbols are declared in `sys/resource.h'.
+-
+- The function and macro names are defined by POSIX, and refer to
+-"priority," but the functions actually have to do with nice values, as
+-the terms are used both in the manual and POSIX.
+-
+- The range of valid nice values depends on the kernel, but typically
+-it runs from `-20' to `20'. A lower nice value corresponds to higher
+-priority for the process. These constants describe the range of
+-priority values:
+-
+-`PRIO_MIN'
+- The lowest valid nice value.
+-
+-`PRIO_MAX'
+- The highest valid nice value.
+-
+- - Function: int getpriority (int CLASS, int ID)
+- Return the nice value of a set of processes; CLASS and ID specify
+- which ones (see below). If the processes specified do not all
+- have the same nice value, this returns the lowest value that any
+- of them has.
+-
+- On success, the return value is `0'. Otherwise, it is `-1' and
+- `ERRNO' is set accordingly. The `errno' values specific to this
+- function are:
+-
+- `ESRCH'
+- The combination of CLASS and ID does not match any existing
+- process.
+-
+- `EINVAL'
+- The value of CLASS is not valid.
+-
+- If the return value is `-1', it could indicate failure, or it could
+- be the nice value. The only way to make certain is to set `errno =
+- 0' before calling `getpriority', then use `errno != 0' afterward
+- as the criterion for failure.
+-
+- - Function: int setpriority (int CLASS, int ID, int NICEVAL)
+- Set the nice value of a set of processes to NICEVAL; CLASS and ID
+- specify which ones (see below).
+-
+- The return value is `0' on success, and `-1' on failure. The
+- following `errno' error condition are possible for this function:
+-
+- `ESRCH'
+- The combination of CLASS and ID does not match any existing
+- process.
+-
+- `EINVAL'
+- The value of CLASS is not valid.
+-
+- `EPERM'
+- The call would set the nice value of a process which is owned
+- by a different user than the calling process (i.e. the target
+- process' real or effective uid does not match the calling
+- process' effective uid) and the calling process does not have
+- `CAP_SYS_NICE' permission.
+-
+- `EACCES'
+- The call would lower the process' nice value and the process
+- does not have `CAP_SYS_NICE' permission.
+-
+-
+- The arguments CLASS and ID together specify a set of processes in
+-which you are interested. These are the possible values of CLASS:
+-
+-`PRIO_PROCESS'
+- One particular process. The argument ID is a process ID (pid).
+-
+-`PRIO_PGRP'
+- All the processes in a particular process group. The argument ID
+- is a process group ID (pgid).
+-
+-`PRIO_USER'
+- All the processes owned by a particular user (i.e. whose real uid
+- indicates the user). The argument ID is a user ID (uid).
+-
+- If the argument ID is 0, it stands for the calling process, its
+-process group, or its owner (real uid), according to CLASS.
+-
+- - Function: int nice (int INCREMENT)
+- Increment the nice value of the calling process by INCREMENT. The
+- return value is the new nice value on success, and `-1' on
+- failure. In the case of failure, `errno' will be set to the same
+- values as for `setpriority'.
+-
+- Here is an equivalent definition of `nice':

+- int
+- nice (int increment)
+- {
+- int result, old = getpriority (PRIO_PROCESS, 0);

+-Querying memory available resources
+-===================================
+-
+- The amount of memory available in the system and the way it is
+-organized determines oftentimes the way programs can and have to work.
+-For functions like `mmap' it is necessary to know about the size of
+-individual memory pages and knowing how much memory is available enables
+-a program to select appropriate sizes for, say, caches. Before we get
+-into these details a few words about memory subsystems in traditional
+-Unix systems will be given.

+-
+-Overview about traditional Unix memory handling
+------------------------------------------------
+-
+- Unix systems normally provide processes virtual address spaces. This
+-means that the addresses of the memory regions do not have to correspond
+-directly to the addresses of the actual physical memory which stores the
+-data. An extra level of indirection is introduced which translates
+-virtual addresses into physical addresses. This is normally done by the
+-hardware of the processor.
+-
+- Using a virtual address space has several advantage. The most
+-important is process isolation. The different processes running on the
+-system cannot interfere directly with each other. No process can write
+-into the address space of another process (except when shared memory is
+-used but then it is wanted and controlled).
+-
+- Another advantage of virtual memory is that the address space the
+-processes see can actually be larger than the physical memory available.
+-The physical memory can be extended by storage on an external media
+-where the content of currently unused memory regions is stored. The
+-address translation can then intercept accesses to these memory regions
+-and make memory content available again by loading the data back into
+-memory. This concept makes it necessary that programs which have to use
+-lots of memory know the difference between available virtual address
+-space and available physical memory. If the working set of virtual
+-memory of all the processes is larger than the available physical memory
+-the system will slow down dramatically due to constant swapping of
+-memory content from the memory to the storage media and back. This is
+-called "thrashing".
+-
+- A final aspect of virtual memory which is important and follows from
+-what is said in the last paragraph is the granularity of the virtual
+-address space handling. When we said that the virtual address handling
+-stores memory content externally it cannot do this on a byte-by-byte
+-basis. The administrative overhead does not allow this (leaving alone
+-the processor hardware). Instead several thousand bytes are handled
+-together and form a "page". The size of each page is always a power of
+-two byte. The smallest page size in use today is 4096, with 8192,
+-16384, and 65536 being other popular sizes.
+-
+-\1f
+-File: libc.info, Node: Query Memory Parameters, Prev: Memory Subsystem, Up: Memory Resources
+-
+-How to get information about the memory subsystem?
+---------------------------------------------------
+-
+- The page size of the virtual memory the process sees is essential to
+-know in several situations. Some programming interface (e.g., `mmap',
+-*note Memory-mapped I/O::) require the user to provide information
+-adjusted to the page size. In the case of `mmap' is it necessary to
+-provide a length argument which is a multiple of the page size.
+-Another place where the knowledge about the page size is useful is in
+-memory allocation. If one allocates pieces of memory in larger chunks
+-which are then subdivided by the application code it is useful to
+-adjust the size of the larger blocks to the page size. If the total
+-memory requirement for the block is close (but not larger) to a multiple
+-of the page size the kernel's memory handling can work more effectively
+-since it only has to allocate memory pages which are fully used. (To do
+-this optimization it is necessary to know a bit about the memory
+-allocator which will require a bit of memory itself for each block and
+-this overhead must not push the total size over the page size multiple.
+-
+- The page size traditionally was a compile time constant. But recent
+-development of processors changed this. Processors now support
+-different page sizes and they can possibly even vary among different
+-processes on the same system. Therefore the system should be queried at
+-runtime about the current page size and no assumptions (except about it
+-being a power of two) should be made.
+-
+- The correct interface to query about the page size is `sysconf'
+-(*note Sysconf Definition::) with the parameter `_SC_PAGESIZE'. There
+-is a much older interface available, too.
+-
+- - Function: int getpagesize (void)
+- The `getpagesize' function returns the page size of the process.
+- This value is fixed for the runtime of the process but can vary in
+- different runs of the application.
+-
+- The function is declared in `unistd.h'.
+-
+- Widely available on System V derived systems is a method to get
+-information about the physical memory the system has. The call
+-
+- sysconf (_SC_PHYS_PAGES)
+-
+-returns the total number of pages of physical the system has. This
+-does not mean all this memory is available. This information can be
+-found using
+-
+- sysconf (_SC_AVPHYS_PAGES)
+-
+- These two values help to optimize applications. The value returned
+-for `_SC_AVPHYS_PAGES' is the amount of memory the application can use
+-without hindering any other process (given that no other process
+-increases its memory usage). The value returned for `_SC_PHYS_PAGES'
+-is more or less a hard limit for the working set. If all applications
+-together constantly use more than that amount of memory the system is
+-in trouble.
+-
+- The GNU C library provides in addition to these already described
+-way to get this information two functions. They are declared in the
+-file `sys/sysinfo.h'. Programmers should prefer to use the `sysconf'
+-method described above.
+-
+- - Function: long int get_phys_pages (void)
+- The `get_phys_pages' function returns the total number of pages of
+- physical the system has. To get the amount of memory this number
+- has to be multiplied by the page size.
+-
+- This function is a GNU extension.
+-
+- - Function: long int get_avphys_pages (void)
+- The `get_phys_pages' function returns the number of available
+- pages of physical the system has. To get the amount of memory
+- this number has to be multiplied by the page size.
+-
+- This function is a GNU extension.

+-
+-Learn about the processors available
+-====================================
+-
+- The use of threads or processes with shared memory allows an
+-application to take advantage of all the processing power a system can
+-provide. If the task can be parallelized the optimal way to write an
+-application is to have at any time as many processes running as there
+-are processors. To determine the number of processors available to the
+-system one can run
+-
+- sysconf (_SC_NPROCESSORS_CONF)
+-
+-which returns the number of processors the operating system configured.
+-But it might be possible for the operating system to disable individual
+-processors and so the call
+-
+- sysconf (_SC_NPROCESSORS_ONLN)
+-
+-returns the number of processors which are currently inline (i.e.,
+-available).
+-
+- For these two pieces of information the GNU C library also provides
+-functions to get the information directly. The functions are declared
+-in `sys/sysinfo.h'.
+-

+-Non-Local Exits
+-***************
+-
+- Sometimes when your program detects an unusual situation inside a

+-immediately return to an outer level of control. This section

+-`longjmp' functions.

+-
+-Introduction to Non-Local Exits
+-===============================
+-
+- As an example of a situation where a non-local exit can be useful,
+-suppose you have an interactive program that has a "main loop" that
+-prompts for and executes commands. Suppose the "read" command reads
+-input from a file, doing some lexical analysis and parsing of the input
+-while processing it. If a low-level input error is detected, it would
+-be useful to be able to return immediately to the "main loop" instead
+-of having to make each of the lexical analysis, parsing, and processing
+-phases all have to explicitly deal with error situations initially
+-detected by nested calls.
+-
+- (On the other hand, if each of these phases has to do a substantial
+-amount of cleanup when it exits--such as closing files, deallocating
+-buffers or other data structures, and the like--then it can be more
+-appropriate to do a normal return and have each phase do its own
+-cleanup, because a non-local exit would bypass the intervening phases
+-and their associated cleanup code entirely. Alternatively, you could
+-use a non-local exit but do the cleanup explicitly either before or
+-after returning to the "main loop".)
+-
+- In some ways, a non-local exit is similar to using the `return'
+-statement to return from a function. But while `return' abandons only
+-a single function call, transferring control back to the point at which
+-it was called, a non-local exit can potentially abandon many levels of
+-nested function calls.
+-
+- You identify return points for non-local exits by calling the
+-function `setjmp'. This function saves information about the execution
+-environment in which the call to `setjmp' appears in an object of type
+-`jmp_buf'. Execution of the program continues normally after the call
+-to `setjmp', but if an exit is later made to this return point by
+-calling `longjmp' with the corresponding `jmp_buf' object, control is
+-transferred back to the point where `setjmp' was called. The return
+-value from `setjmp' is used to distinguish between an ordinary return
+-and a return made by a call to `longjmp', so calls to `setjmp' usually
+-appear in an `if' statement.
+-
+- Here is how the example program described above might be set up:
+-
+- #include <setjmp.h>
+- #include <stdlib.h>
+- #include <stdio.h>
+-
+- jmp_buf main_loop;
+-
+- void
+- abort_to_main_loop (int status)
+- {
+- longjmp (main_loop, status);
+- }
+-
+- int
+- main (void)
+- {
+- while (1)
+- if (setjmp (main_loop))
+- puts ("Back at main loop....");
+- else
+- do_command ();
+- }
+-
+-
+- void
+- do_command (void)
+- {
+- char buffer[128];
+- if (fgets (buffer, 128, stdin) == NULL)
+- abort_to_main_loop (-1);
+- else
+- exit (EXIT_SUCCESS);
+- }
+-
+- The function `abort_to_main_loop' causes an immediate transfer of
+-control back to the main loop of the program, no matter where it is
+-called from.
+-
+- The flow of control inside the `main' function may appear a little
+-mysterious at first, but it is actually a common idiom with `setjmp'.
+-A normal call to `setjmp' returns zero, so the "else" clause of the
+-conditional is executed. If `abort_to_main_loop' is called somewhere
+-within the execution of `do_command', then it actually appears as if
+-the _same_ call to `setjmp' in `main' were returning a second time with
+-a value of `-1'.
+-
+- So, the general pattern for using `setjmp' looks something like:
+-
+- if (setjmp (BUFFER))
+- /* Code to clean up after premature return. */
+- ...
+- else
+- /* Code to be executed normally after setting up the return point. */
+- ...

+-
+-Details of Non-Local Exits
+-==========================
+-
+- Here are the details on the functions and data structures used for
+-performing non-local exits. These facilities are declared in
+-`setjmp.h'.
+-
+- - Data Type: jmp_buf
+- Objects of type `jmp_buf' hold the state information to be
+- restored by a non-local exit. The contents of a `jmp_buf'
+- identify a specific place to return to.
+-
+- - Macro: int setjmp (jmp_buf STATE)
+- When called normally, `setjmp' stores information about the
+- execution state of the program in STATE and returns zero. If
+- `longjmp' is later used to perform a non-local exit to this STATE,
+- `setjmp' returns a nonzero value.
+-
+- - Function: void longjmp (jmp_buf STATE, int VALUE)
+- This function restores current execution to the state saved in
+- STATE, and continues execution from the call to `setjmp' that
+- established that return point. Returning from `setjmp' by means of
+- `longjmp' returns the VALUE argument that was passed to `longjmp',
+- rather than `0'. (But if VALUE is given as `0', `setjmp' returns
+- `1').
+-
+- There are a lot of obscure but important restrictions on the use of
+-`setjmp' and `longjmp'. Most of these restrictions are present because
+-non-local exits require a fair amount of magic on the part of the C
+-compiler and can interact with other parts of the language in strange
+-ways.
+-
+- The `setjmp' function is actually a macro without an actual function
+-definition, so you shouldn't try to `#undef' it or take its address.
+-In addition, calls to `setjmp' are safe in only the following contexts:
+-
+- * As the test expression of a selection or iteration statement (such
+- as `if', `switch', or `while').
+-
+- * As one operand of a equality or comparison operator that appears
+- as the test expression of a selection or iteration statement. The
+- other operand must be an integer constant expression.
+-
+- * As the operand of a unary `!' operator, that appears as the test
+- expression of a selection or iteration statement.
+-
+- * By itself as an expression statement.
+-
+- Return points are valid only during the dynamic extent of the
+-function that called `setjmp' to establish them. If you `longjmp' to a
+-return point that was established in a function that has already
+-returned, unpredictable and disastrous things are likely to happen.
+-
+- You should use a nonzero VALUE argument to `longjmp'. While
+-`longjmp' refuses to pass back a zero argument as the return value from
+-`setjmp', this is intended as a safety net against accidental misuse
+-and is not really good programming style.
+-
+- When you perform a non-local exit, accessible objects generally
+-retain whatever values they had at the time `longjmp' was called. The
+-exception is that the values of automatic variables local to the
+-function containing the `setjmp' call that have been changed since the
+-call to `setjmp' are indeterminate, unless you have declared them
+-`volatile'.

+-
+-Non-Local Exits and Signals
+-===========================
+-
+- In BSD Unix systems, `setjmp' and `longjmp' also save and restore
+-the set of blocked signals; see *Note Blocking Signals::. However, the
+-POSIX.1 standard requires `setjmp' and `longjmp' not to change the set
+-of blocked signals, and provides an additional pair of functions
+-(`sigsetjmp' and `siglongjmp') to get the BSD behavior.
+-
+- The behavior of `setjmp' and `longjmp' in the GNU library is
+-controlled by feature test macros; see *Note Feature Test Macros::. The
+-default in the GNU system is the POSIX.1 behavior rather than the BSD
+-behavior.
+-
+- The facilities in this section are declared in the header file
+-`setjmp.h'.
+-
+- - Data Type: sigjmp_buf
+- This is similar to `jmp_buf', except that it can also store state
+- information about the set of blocked signals.
+-
+- - Function: int sigsetjmp (sigjmp_buf STATE, int SAVESIGS)
+- This is similar to `setjmp'. If SAVESIGS is nonzero, the set of
+- blocked signals is saved in STATE and will be restored if a
+- `siglongjmp' is later performed with this STATE.
+-
+- - Function: void siglongjmp (sigjmp_buf STATE, int VALUE)
+- This is similar to `longjmp' except for the type of its STATE
+- argument. If the `sigsetjmp' call that set this STATE used a
+- nonzero SAVESIGS flag, `siglongjmp' also restores the set of
+- blocked signals.

+-
+-Complete Context Control
+-========================
+-
+- The Unix standard one more set of function to control the execution
+-path and these functions are more powerful than those discussed in this
+-chapter so far. These function were part of the original System V API
+-and by this route were added to the Unix API. Beside on branded Unix
+-implementations these interfaces are not widely available. Not all
+-platforms and/or architectures the GNU C Library is available on provide
+-this interface. Use `configure' to detect the availability.
+-
+- Similar to the `jmp_buf' and `sigjmp_buf' types used for the
+-variables to contain the state of the `longjmp' functions the
+-interfaces of interest here have an appropriate type as well. Objects
+-of this type are normally much larger since more information is
+-contained. The type is also used in a few more places as we will see.
+-The types and functions described in this section are all defined and
+-declared respectively in the `ucontext.h' header file.
+-
+- - Data Type: ucontext_t
+- The `ucontext_t' type is defined as a structure with as least the
+- following elements:
+-
+- `ucontext_t *uc_link'
+- This is a pointer to the next context structure which is used
+- if the context described in the current structure returns.
+-
+- `sigset_t uc_sigmask'
+- Set of signals which are blocked when this context is used.
+-
+- `stack_t uc_stack'
+- Stack used for this context. The value need not be (and
+- normally is not) the stack pointer. *Note Signal Stack::.
+-
+- `mcontext_t uc_mcontext'
+- This element contains the actual state of the process. The
+- `mcontext_t' type is also defined in this header but the
+- definition should be treated as opaque. Any use of knowledge
+- of the type makes applications less portable.
+-
+-
+- Objects of this type have to be created by the user. The
+-initialization and modification happens through one of the following
+-functions:
+-
+- - Function: int getcontext (ucontext_t *UCP)
+- The `getcontext' function initializes the variable pointed to by
+- UCP with the context of the calling thread. The context contains
+- the content of the registers, the signal mask, and the current
+- stack. Executing the contents would start at the point where the
+- `getcontext' call just returned.
+-
+- The function returns `0' if successful. Otherwise it returns `-1'
+- and sets ERRNO accordingly.
+-
+- The `getcontext' function is similar to `setjmp' but it does not
+-provide an indication of whether the function returns for the first
+-time or whether the initialized context was used and the execution is
+-resumed at just that point. If this is necessary the user has to take
+-determine this herself. This must be done carefully since the context
+-contains registers which might contain register variables. This is a
+-good situation to define variables with `volatile'.
+-
+- Once the context variable is initialized it can be used as is or it
+-can be modified. The latter is normally done to implement co-routines
+-or similar constructs. The `makecontext' function is what has to be
+-used to do that.
+-
+- - Function: void makecontext (ucontext_t *UCP, void (*FUNC) (void),
+- int ARGC, ...)
+- The UCP parameter passed to the `makecontext' shall be initialized
+- by a call to `getcontext'. The context will be modified to in a
+- way so that if the context is resumed it will start by calling the
+- function `func' which gets ARGC integer arguments passed. The
+- integer arguments which are to be passed should follow the ARGC
+- parameter in the call to `makecontext'.
+-
+- Before the call to this function the `uc_stack' and `uc_link'
+- element of the UCP structure should be initialized. The
+- `uc_stack' element describes the stack which is used for this
+- context. No two contexts which are used at the same time should
+- use the same memory region for a stack.
+-
+- The `uc_link' element of the object pointed to by UCP should be a
+- pointer to the context to be executed when the function FUNC
+- returns or it should be a null pointer. See `setcontext' for more
+- information about the exact use.
+-
+- While allocating the memory for the stack one has to be careful.
+-Most modern processors keep track of whether a certain memory region is
+-allowed to contain code which is executed or not. Data segments and
+-heap memory is normally not tagged to allow this. The result is that
+-programs would fail. Examples for such code include the calling
+-sequences the GNU C compiler generates for calls to nested functions.
+-Safe ways to allocate stacks correctly include using memory on the
+-original threads stack or explicitly allocate memory tagged for
+-execution using (*note Memory-mapped I/O::).
+-
+- *Compatibility note*: The current Unix standard is very imprecise
+-about the way the stack is allocated. All implementations seem to agree
+-that the `uc_stack' element must be used but the values stored in the
+-elements of the `stack_t' value are unclear. The GNU C library and
+-most other Unix implementations require the `ss_sp' value of the
+-`uc_stack' element to point to the base of the memory region allocated
+-for the stack and the size of the memory region is stored in `ss_size'.
+-There are implements out there which require `ss_sp' to be set to the
+-value the stack pointer will have (which can depending on the direction
+-the stack grows be different). This difference makes the `makecontext'
+-function hard to use and it requires detection of the platform at
+-compile time.
+-
+- - Function: int setcontext (const ucontext_t *UCP)
+- The `setcontext' function restores the context described by UCP.
+- The context is not modified and can be reused as often as wanted.
+-
+- If the context was created by `getcontext' execution resumes with
+- the registers filled with the same values and the same stack as if
+- the `getcontext' call just returned.
+-
+- If the context was modified with a call to `makecontext' execution
+- continues with the function passed to `makecontext' which gets the
+- specified parameters passed. If this function returns execution is
+- resumed in the context which was referenced by the `uc_link'
+- element of the context structure passed to `makecontext' at the
+- time of the call. If `uc_link' was a null pointer the application
+- terminates in this case.
+-
+- Since the context contains information about the stack no two
+- threads should use the same context at the same time. The result
+- in most cases would be disastrous.
+-
+- The `setcontext' function does not return unless an error occurred
+- in which case it returns `-1'.
+-
+- The `setcontext' function simply replaces the current context with
+-the one described by the UCP parameter. This is often useful but there
+-are situations where the current context has to be preserved.
+-
+- - Function: int swapcontext (ucontext_t *restrict OUCP, const
+- ucontext_t *restrict UCP)
+- The `swapcontext' function is similar to `setcontext' but instead
+- of just replacing the current context the latter is first saved in
+- the object pointed to by OUCP as if this was a call to
+- `getcontext'. The saved context would resume after the call to
+- `swapcontext'.
+-
+- Once the current context is saved the context described in UCP is
+- installed and execution continues as described in this context.
+-
+- If `swapcontext' succeeds the function does not return unless the
+- context OUCP is used without prior modification by `makecontext'.
+- The return value in this case is `0'. If the function fails it
+- returns `-1' and set ERRNO accordingly.
+-
+-Example for SVID Context Handling
+-=================================
+-
+- The easiest way to use the context handling functions is as a
+-replacement for `setjmp' and `longjmp'. The context contains on most
+-platforms more information which might lead to less surprises but this
+-also means using these functions is more expensive (beside being less
+-portable).
+-
+- int
+- random_search (int n, int (*fp) (int, ucontext_t *))
+- {
+- volatile int cnt = 0;
+- ucontext_t uc;
+-
+- /* Safe current context. */
+- if (getcontext (&uc) < 0)
+- return -1;
+-
+- /* If we have not tried N times try again. */
+- if (cnt++ < n)
+- /* Call the function with a new random number
+- and the context. */
+- if (fp (rand (), &uc) != 0)
+- /* We found what we were looking for. */
+- return 1;
+-
+- /* Not found. */
+- return 0;
+- }
+-
+- Using contexts in such a way enables emulating exception handling.
+-The search functions passed in the FP parameter could be very large,
+-nested, and complex which would make it complicated (or at least would
+-require a lot of code) to leave the function with an error value which
+-has to be passed down to the caller. By using the context it is
+-possible to leave the search function in one step and allow restarting
+-the search which also has the nice side effect that it can be
+-significantly faster.
+-
+- Something which is harder to implement with `setjmp' and `longjmp'
+-is to switch temporarily to a different execution path and then resume
+-where execution was stopped.

+-
+- return 0;
+- }
+-
+- This an example how the context functions can be used to implement
+-co-routines or cooperative multi-threading. All that has to be done is
+-to call every once in a while `swapcontext' to continue running a
+-different context. It is not allowed to do the context switching from
+-the signal handler directly since neither `setcontext' nor
+-`swapcontext' are functions which can be called from a signal handler.
+-But setting a variable in the signal handler and checking it in the
+-body of the functions which are executed. Since `swapcontext' is
+-saving the current context it is possible to have multiple different
+-scheduling points in the code. Execution will always resume where it
+-was left.

+-Signal Handling
+-***************
+-
+- A "signal" is a software interrupt delivered to a process. The
+-operating system uses signals to report exceptional situations to an
+-executing program. Some signals report errors such as references to
+-invalid memory addresses; others report asynchronous events, such as
+-disconnection of a phone line.
+-
+- The GNU C library defines a variety of signal types, each for a
+-particular kind of event. Some kinds of events make it inadvisable or
+-impossible for the program to proceed as usual, and the corresponding
+-signals normally abort the program. Other kinds of signals that report
+-harmless events are ignored by default.
+-
+- If you anticipate an event that causes signals, you can define a
+-handler function and tell the operating system to run it when that
+-particular type of signal arrives.
+-
+- Finally, one process can send a signal to another process; this
+-allows a parent process to abort a child, or two related processes to
+-communicate and synchronize.

+-
+-Some Kinds of Signals
+----------------------
+-
+- A signal reports the occurrence of an exceptional event. These are
+-some of the events that can cause (or "generate", or "raise") a signal:
+-
+- * A program error such as dividing by zero or issuing an address
+- outside the valid range.
+-
+- * A user request to interrupt or terminate the program. Most
+- environments are set up to let a user suspend the program by
+- typing `C-z', or terminate it with `C-c'. Whatever key sequence
+- is used, the operating system sends the proper signal to interrupt
+- the process.
+-
+- * The termination of a child process.
+-
+- * Expiration of a timer or alarm.
+-
+- * A call to `kill' or `raise' by the same process.
+-
+- * A call to `kill' from another process. Signals are a limited but
+- useful form of interprocess communication.
+-
+- * An attempt to perform an I/O operation that cannot be done.
+- Examples are reading from a pipe that has no writer (*note Pipes
+- and FIFOs::), and reading or writing to a terminal in certain
+- situations (*note Job Control::).
+-
+- Each of these kinds of events (excepting explicit calls to `kill'
+-and `raise') generates its own particular kind of signal. The various
+-kinds of signals are listed and described in detail in *Note Standard
+-Signals::.

+-
+-Concepts of Signal Generation
+------------------------------
+-
+- In general, the events that generate signals fall into three major
+-categories: errors, external events, and explicit requests.
+-
+- An error means that a program has done something invalid and cannot
+-continue execution. But not all kinds of errors generate signals--in
+-fact, most do not. For example, opening a nonexistent file is an error,
+-but it does not raise a signal; instead, `open' returns `-1'. In
+-general, errors that are necessarily associated with certain library
+-functions are reported by returning a value that indicates an error.
+-The errors which raise signals are those which can happen anywhere in
+-the program, not just in library calls. These include division by zero
+-and invalid memory addresses.
+-
+- An external event generally has to do with I/O or other processes.
+-These include the arrival of input, the expiration of a timer, and the
+-termination of a child process.
+-
+- An explicit request means the use of a library function such as
+-`kill' whose purpose is specifically to generate a signal.
+-
+- Signals may be generated "synchronously" or "asynchronously". A
+-synchronous signal pertains to a specific action in the program, and is
+-delivered (unless blocked) during that action. Most errors generate
+-signals synchronously, and so do explicit requests by a process to
+-generate a signal for that same process. On some machines, certain
+-kinds of hardware errors (usually floating-point exceptions) are not
+-reported completely synchronously, but may arrive a few instructions
+-later.
+-
+- Asynchronous signals are generated by events outside the control of
+-the process that receives them. These signals arrive at unpredictable
+-times during execution. External events generate signals
+-asynchronously, and so do explicit requests that apply to some other
+-process.
+-
+- A given type of signal is either typically synchronous or typically
+-asynchronous. For example, signals for errors are typically synchronous
+-because errors generate signals synchronously. But any type of signal

+-How Signals Are Delivered
+--------------------------
+-
+- When a signal is generated, it becomes "pending". Normally it
+-remains pending for just a short period of time and then is "delivered"
+-to the process that was signaled. However, if that kind of signal is
+-currently "blocked", it may remain pending indefinitely--until signals
+-of that kind are "unblocked". Once unblocked, it will be delivered
+-immediately. *Note Blocking Signals::.
+-
+- When the signal is delivered, whether right away or after a long
+-delay, the "specified action" for that signal is taken. For certain
+-signals, such as `SIGKILL' and `SIGSTOP', the action is fixed, but for
+-most signals, the program has a choice: ignore the signal, specify a
+-"handler function", or accept the "default action" for that kind of
+-signal. The program specifies its choice using functions such as
+-`signal' or `sigaction' (*note Signal Actions::). We sometimes say
+-that a handler "catches" the signal. While the handler is running,
+-that particular signal is normally blocked.
+-
+- If the specified action for a kind of signal is to ignore it, then
+-any such signal which is generated is discarded immediately. This
+-happens even if the signal is also blocked at the time. A signal
+-discarded in this way will never be delivered, not even if the program
+-subsequently specifies a different action for that kind of signal and
+-then unblocks it.
+-
+- If a signal arrives which the program has neither handled nor
+-ignored, its "default action" takes place. Each kind of signal has its
+-own default action, documented below (*note Standard Signals::). For
+-most kinds of signals, the default action is to terminate the process.
+-For certain kinds of signals that represent "harmless" events, the
+-default action is to do nothing.
+-
+- When a signal terminates a process, its parent process can determine
+-the cause of termination by examining the termination status code
+-reported by the `wait' or `waitpid' functions. (This is discussed in
+-more detail in *Note Process Completion::.) The information it can get
+-includes the fact that termination was due to a signal and the kind of
+-signal involved. If a program you run from a shell is terminated by a
+-signal, the shell typically prints some kind of error message.
+-
+- The signals that normally represent program errors have a special
+-property: when one of these signals terminates the process, it also
+-writes a "core dump file" which records the state of the process at the
+-time of termination. You can examine the core dump with a debugger to
+-investigate what caused the error.
+-
+- If you raise a "program error" signal by explicit request, and this
+-terminates the process, it makes a core dump file just as if the signal
+-had been due directly to an error.

+-Standard Signals
+-================
+-
+- This section lists the names for various standard kinds of signals
+-and describes what kind of event they mean. Each signal name is a macro
+-which stands for a positive integer--the "signal number" for that kind
+-of signal. Your programs should never make assumptions about the
+-numeric code for a particular kind of signal, but rather refer to them
+-always by the names defined here. This is because the number for a
+-given kind of signal can vary from system to system, but the meanings of
+-the names are standardized and fairly uniform.
+-
+- The signal names are defined in the header file `signal.h'.
+-
+- - Macro: int NSIG
+- The value of this symbolic constant is the total number of signals
+- defined. Since the signal numbers are allocated consecutively,
+- `NSIG' is also one greater than the largest defined signal number.

+-
+-Program Error Signals
+----------------------
+-
+- The following signals are generated when a serious program error is
+-detected by the operating system or the computer itself. In general,
+-all of these signals are indications that your program is seriously
+-broken in some way, and there's usually no way to continue the
+-computation which encountered the error.
+-
+- Some programs handle program error signals in order to tidy up before
+-terminating; for example, programs that turn off echoing of terminal
+-input should handle program error signals in order to turn echoing back
+-on. The handler should end by specifying the default action for the
+-signal that happened and then reraising it; this will cause the program
+-to terminate with that signal, as if it had not had a handler. (*Note
+-Termination in Handler::.)
+-
+- Termination is the sensible ultimate outcome from a program error in
+-most programs. However, programming systems such as Lisp that can load
+-compiled user programs might need to keep executing even if a user
+-program incurs an error. These programs have handlers which use
+-`longjmp' to return control to the command level.
+-
+- The default action for all of these signals is to cause the process
+-to terminate. If you block or ignore these signals or establish
+-handlers for them that return normally, your program will probably
+-break horribly when such signals happen, unless they are generated by
+-`raise' or `kill' instead of a real error.
+-
+- When one of these program error signals terminates a process, it also
+-writes a "core dump file" which records the state of the process at the
+-time of termination. The core dump file is named `core' and is written
+-in whichever directory is current in the process at the time. (On the
+-GNU system, you can specify the file name for core dumps with the
+-environment variable `COREFILE'.) The purpose of core dump files is so
+-that you can examine them with a debugger to investigate what caused
+-the error.
+-
+- - Macro: int SIGFPE
+- The `SIGFPE' signal reports a fatal arithmetic error. Although the
+- name is derived from "floating-point exception", this signal
+- actually covers all arithmetic errors, including division by zero
+- and overflow. If a program stores integer data in a location
+- which is then used in a floating-point operation, this often
+- causes an "invalid operation" exception, because the processor
+- cannot recognize the data as a floating-point number.
+-
+- Actual floating-point exceptions are a complicated subject because
+- there are many types of exceptions with subtly different meanings,
+- and the `SIGFPE' signal doesn't distinguish between them. The
+- `IEEE Standard for Binary Floating-Point Arithmetic (ANSI/IEEE Std
+- 754-1985 and ANSI/IEEE Std 854-1987)' defines various
+- floating-point exceptions and requires conforming computer systems
+- to report their occurrences. However, this standard does not
+- specify how the exceptions are reported, or what kinds of handling
+- and control the operating system can offer to the programmer.
+-
+- BSD systems provide the `SIGFPE' handler with an extra argument that
+-distinguishes various causes of the exception. In order to access this
+-argument, you must define the handler to accept two arguments, which
+-means you must cast it to a one-argument function type in order to
+-establish the handler. The GNU library does provide this extra
+-argument, but the value is meaningful only on operating systems that
+-provide the information (BSD systems and GNU systems).
+-
+-`FPE_INTOVF_TRAP'
+- Integer overflow (impossible in a C program unless you enable
+- overflow trapping in a hardware-specific fashion).
+-
+-`FPE_INTDIV_TRAP'
+- Integer division by zero.
+-
+-`FPE_SUBRNG_TRAP'
+- Subscript-range (something that C programs never check for).
+-
+-`FPE_FLTOVF_TRAP'
+- Floating overflow trap.
+-
+-`FPE_FLTDIV_TRAP'
+- Floating/decimal division by zero.
+-
+-`FPE_FLTUND_TRAP'
+- Floating underflow trap. (Trapping on floating underflow is not
+- normally enabled.)
+-
+-`FPE_DECOVF_TRAP'
+- Decimal overflow trap. (Only a few machines have decimal
+- arithmetic and C never uses it.)
+-
+- - Macro: int SIGILL
+- The name of this signal is derived from "illegal instruction"; it
+- usually means your program is trying to execute garbage or a
+- privileged instruction. Since the C compiler generates only valid
+- instructions, `SIGILL' typically indicates that the executable
+- file is corrupted, or that you are trying to execute data. Some
+- common ways of getting into the latter situation are by passing an
+- invalid object where a pointer to a function was expected, or by
+- writing past the end of an automatic array (or similar problems
+- with pointers to automatic variables) and corrupting other data on
+- the stack such as the return address of a stack frame.
+-
+- `SIGILL' can also be generated when the stack overflows, or when
+- the system has trouble running the handler for a signal.
+-
+- - Macro: int SIGSEGV
+- This signal is generated when a program tries to read or write
+- outside the memory that is allocated for it, or to write memory
+- that can only be read. (Actually, the signals only occur when the
+- program goes far enough outside to be detected by the system's
+- memory protection mechanism.) The name is an abbreviation for
+- "segmentation violation".
+-
+- Common ways of getting a `SIGSEGV' condition include dereferencing
+- a null or uninitialized pointer, or when you use a pointer to step
+- through an array, but fail to check for the end of the array. It
+- varies among systems whether dereferencing a null pointer generates
+- `SIGSEGV' or `SIGBUS'.
+-
+- - Macro: int SIGBUS
+- This signal is generated when an invalid pointer is dereferenced.
+- Like `SIGSEGV', this signal is typically the result of
+- dereferencing an uninitialized pointer. The difference between
+- the two is that `SIGSEGV' indicates an invalid access to valid
+- memory, while `SIGBUS' indicates an access to an invalid address.
+- In particular, `SIGBUS' signals often result from dereferencing a
+- misaligned pointer, such as referring to a four-word integer at an
+- address not divisible by four. (Each kind of computer has its own
+- requirements for address alignment.)
+-
+- The name of this signal is an abbreviation for "bus error".
+-
+- - Macro: int SIGABRT
+- This signal indicates an error detected by the program itself and
+- reported by calling `abort'. *Note Aborting a Program::.
+-
+- - Macro: int SIGIOT
+- Generated by the PDP-11 "iot" instruction. On most machines, this
+- is just another name for `SIGABRT'.
+-
+- - Macro: int SIGTRAP
+- Generated by the machine's breakpoint instruction, and possibly
+- other trap instructions. This signal is used by debuggers. Your
+- program will probably only see `SIGTRAP' if it is somehow
+- executing bad instructions.
+-
+- - Macro: int SIGEMT
+- Emulator trap; this results from certain unimplemented instructions
+- which might be emulated in software, or the operating system's
+- failure to properly emulate them.
+-
+- - Macro: int SIGSYS
+- Bad system call; that is to say, the instruction to trap to the
+- operating system was executed, but the code number for the system
+- call to perform was invalid.

+-
+-Termination Signals
+--------------------
+-
+- These signals are all used to tell a process to terminate, in one way
+-or another. They have different names because they're used for slightly
+-different purposes, and programs might want to handle them differently.
+-
+- The reason for handling these signals is usually so your program can
+-tidy up as appropriate before actually terminating. For example, you
+-might want to save state information, delete temporary files, or restore
+-the previous terminal modes. Such a handler should end by specifying
+-the default action for the signal that happened and then reraising it;
+-this will cause the program to terminate with that signal, as if it had
+-not had a handler. (*Note Termination in Handler::.)
+-
+- The (obvious) default action for all of these signals is to cause the
+-process to terminate.
+-
+- - Macro: int SIGTERM
+- The `SIGTERM' signal is a generic signal used to cause program
+- termination. Unlike `SIGKILL', this signal can be blocked,
+- handled, and ignored. It is the normal way to politely ask a
+- program to terminate.
+-
+- The shell command `kill' generates `SIGTERM' by default.
+-
+- - Macro: int SIGINT
+- The `SIGINT' ("program interrupt") signal is sent when the user
+- types the INTR character (normally `C-c'). *Note Special
+- Characters::, for information about terminal driver support for
+- `C-c'.
+-
+- - Macro: int SIGQUIT
+- The `SIGQUIT' signal is similar to `SIGINT', except that it's
+- controlled by a different key--the QUIT character, usually
+- `C-\'--and produces a core dump when it terminates the process,
+- just like a program error signal. You can think of this as a
+- program error condition "detected" by the user.
+-
+- *Note Program Error Signals::, for information about core dumps.
+- *Note Special Characters::, for information about terminal driver
+- support.
+-
+- Certain kinds of cleanups are best omitted in handling `SIGQUIT'.
+- For example, if the program creates temporary files, it should
+- handle the other termination requests by deleting the temporary
+- files. But it is better for `SIGQUIT' not to delete them, so that
+- the user can examine them in conjunction with the core dump.
+-
+- - Macro: int SIGKILL
+- The `SIGKILL' signal is used to cause immediate program
+- termination. It cannot be handled or ignored, and is therefore
+- always fatal. It is also not possible to block this signal.
+-
+- This signal is usually generated only by explicit request. Since
+- it cannot be handled, you should generate it only as a last
+- resort, after first trying a less drastic method such as `C-c' or
+- `SIGTERM'. If a process does not respond to any other termination
+- signals, sending it a `SIGKILL' signal will almost always cause it
+- to go away.
+-
+- In fact, if `SIGKILL' fails to terminate a process, that by itself
+- constitutes an operating system bug which you should report.
+-
+- The system will generate `SIGKILL' for a process itself under some
+- unusual conditions where the program cannot possibly continue to
+- run (even to run a signal handler).
+-
+- - Macro: int SIGHUP
+- The `SIGHUP' ("hang-up") signal is used to report that the user's
+- terminal is disconnected, perhaps because a network or telephone
+- connection was broken. For more information about this, see *Note
+- Control Modes::.
+-
+- This signal is also used to report the termination of the
+- controlling process on a terminal to jobs associated with that
+- session; this termination effectively disconnects all processes in
+- the session from the controlling terminal. For more information,
+- see *Note Termination Internals::.
+-
+-\1f
+-File: libc.info, Node: Alarm Signals, Next: Asynchronous I/O Signals, Prev: Termination Signals, Up: Standard Signals
+-
+-Alarm Signals
+--------------
+-
+- These signals are used to indicate the expiration of timers. *Note
+-Setting an Alarm::, for information about functions that cause these
+-signals to be sent.
+-
+- The default behavior for these signals is to cause program
+-termination. This default is rarely useful, but no other default would
+-be useful; most of the ways of using these signals would require
+-handler functions in any case.
+-
+- - Macro: int SIGALRM
+- This signal typically indicates expiration of a timer that
+- measures real or clock time. It is used by the `alarm' function,
+- for example.
+-
+- - Macro: int SIGVTALRM
+- This signal typically indicates expiration of a timer that
+- measures CPU time used by the current process. The name is an
+- abbreviation for "virtual time alarm".
+-
+- - Macro: int SIGPROF
+- This signal typically indicates expiration of a timer that measures
+- both CPU time used by the current process, and CPU time expended on
+- behalf of the process by the system. Such a timer is used to
+- implement code profiling facilities, hence the name of this signal.

+-File: libc.info, Node: Asynchronous I/O Signals, Next: Job Control Signals, Prev: Alarm Signals, Up: Standard Signals
+-
+-Asynchronous I/O Signals
+-------------------------
+-
+- The signals listed in this section are used in conjunction with
+-asynchronous I/O facilities. You have to take explicit action by
+-calling `fcntl' to enable a particular file descriptor to generate
+-these signals (*note Interrupt Input::). The default action for these
+-signals is to ignore them.
+-
+- - Macro: int SIGIO
+- This signal is sent when a file descriptor is ready to perform
+- input or output.
+-
+- On most operating systems, terminals and sockets are the only
+- kinds of files that can generate `SIGIO'; other kinds, including
+- ordinary files, never generate `SIGIO' even if you ask them to.
+-
+- In the GNU system `SIGIO' will always be generated properly if you
+- successfully set asynchronous mode with `fcntl'.
+-
+- - Macro: int SIGURG
+- This signal is sent when "urgent" or out-of-band data arrives on a
+- socket. *Note Out-of-Band Data::.
+-
+- - Macro: int SIGPOLL
+- This is a System V signal name, more or less similar to `SIGIO'.
+- It is defined only for compatibility.
+-
+-\1f
+-File: libc.info, Node: Job Control Signals, Next: Operation Error Signals, Prev: Asynchronous I/O Signals, Up: Standard Signals
+-
+-Job Control Signals
+--------------------
+-
+- These signals are used to support job control. If your system
+-doesn't support job control, then these macros are defined but the
+-signals themselves can't be raised or handled.
+-
+- You should generally leave these signals alone unless you really
+-understand how job control works. *Note Job Control::.
+-
+- - Macro: int SIGCHLD
+- This signal is sent to a parent process whenever one of its child
+- processes terminates or stops.
+-
+- The default action for this signal is to ignore it. If you
+- establish a handler for this signal while there are child
+- processes that have terminated but not reported their status via
+- `wait' or `waitpid' (*note Process Completion::), whether your new
+- handler applies to those processes or not depends on the
+- particular operating system.
+-
+- - Macro: int SIGCLD
+- This is an obsolete name for `SIGCHLD'.
+-
+- - Macro: int SIGCONT
+- You can send a `SIGCONT' signal to a process to make it continue.
+- This signal is special--it always makes the process continue if it
+- is stopped, before the signal is delivered. The default behavior
+- is to do nothing else. You cannot block this signal. You can set
+- a handler, but `SIGCONT' always makes the process continue
+- regardless.
+-
+- Most programs have no reason to handle `SIGCONT'; they simply
+- resume execution without realizing they were ever stopped. You
+- can use a handler for `SIGCONT' to make a program do something
+- special when it is stopped and continued--for example, to reprint
+- a prompt when it is suspended while waiting for input.
+-
+- - Macro: int SIGSTOP
+- The `SIGSTOP' signal stops the process. It cannot be handled,
+- ignored, or blocked.
+-
+- - Macro: int SIGTSTP
+- The `SIGTSTP' signal is an interactive stop signal. Unlike
+- `SIGSTOP', this signal can be handled and ignored.
+-
+- Your program should handle this signal if you have a special need
+- to leave files or system tables in a secure state when a process is
+- stopped. For example, programs that turn off echoing should handle
+- `SIGTSTP' so they can turn echoing back on before stopping.
+-
+- This signal is generated when the user types the SUSP character
+- (normally `C-z'). For more information about terminal driver
+- support, see *Note Special Characters::.
+-
+- - Macro: int SIGTTIN
+- A process cannot read from the user's terminal while it is running
+- as a background job. When any process in a background job tries to
+- read from the terminal, all of the processes in the job are sent a
+- `SIGTTIN' signal. The default action for this signal is to stop
+- the process. For more information about how this interacts with
+- the terminal driver, see *Note Access to the Terminal::.
+-
+- - Macro: int SIGTTOU
+- This is similar to `SIGTTIN', but is generated when a process in a
+- background job attempts to write to the terminal or set its modes.
+- Again, the default action is to stop the process. `SIGTTOU' is
+- only generated for an attempt to write to the terminal if the
+- `TOSTOP' output mode is set; *note Output Modes::.
+-
+- While a process is stopped, no more signals can be delivered to it
+-until it is continued, except `SIGKILL' signals and (obviously)
+-`SIGCONT' signals. The signals are marked as pending, but not
+-delivered until the process is continued. The `SIGKILL' signal always
+-causes termination of the process and can't be blocked, handled or
+-ignored. You can ignore `SIGCONT', but it always causes the process to
+-be continued anyway if it is stopped. Sending a `SIGCONT' signal to a
+-process causes any pending stop signals for that process to be
+-discarded. Likewise, any pending `SIGCONT' signals for a process are
+-discarded when it receives a stop signal.
+-
+- When a process in an orphaned process group (*note Orphaned Process
+-Groups::) receives a `SIGTSTP', `SIGTTIN', or `SIGTTOU' signal and does
+-not handle it, the process does not stop. Stopping the process would
+-probably not be very useful, since there is no shell program that will
+-notice it stop and allow the user to continue it. What happens instead
+-depends on the operating system you are using. Some systems may do
+-nothing; others may deliver another signal instead, such as `SIGKILL'
+-or `SIGHUP'. In the GNU system, the process dies with `SIGKILL'; this
+-avoids the problem of many stopped, orphaned processes lying around the
+-system.

+-
+-Operation Error Signals
+------------------------
+-
+- These signals are used to report various errors generated by an
+-operation done by the program. They do not necessarily indicate a
+-programming error in the program, but an error that prevents an
+-operating system call from completing. The default action for all of
+-them is to cause the process to terminate.
+-
+- - Macro: int SIGPIPE
+- Broken pipe. If you use pipes or FIFOs, you have to design your
+- application so that one process opens the pipe for reading before
+- another starts writing. If the reading process never starts, or
+- terminates unexpectedly, writing to the pipe or FIFO raises a
+- `SIGPIPE' signal. If `SIGPIPE' is blocked, handled or ignored,
+- the offending call fails with `EPIPE' instead.
+-
+- Pipes and FIFO special files are discussed in more detail in *Note
+- Pipes and FIFOs::.
+-
+- Another cause of `SIGPIPE' is when you try to output to a socket
+- that isn't connected. *Note Sending Data::.
+-
+- - Macro: int SIGLOST
+- Resource lost. This signal is generated when you have an advisory
+- lock on an NFS file, and the NFS server reboots and forgets about
+- your lock.
+-
+- In the GNU system, `SIGLOST' is generated when any server program
+- dies unexpectedly. It is usually fine to ignore the signal;
+- whatever call was made to the server that died just returns an
+- error.
+-
+- - Macro: int SIGXCPU
+- CPU time limit exceeded. This signal is generated when the process
+- exceeds its soft resource limit on CPU time. *Note Limits on
+- Resources::.
+-
+- - Macro: int SIGXFSZ
+- File size limit exceeded. This signal is generated when the
+- process attempts to extend a file so it exceeds the process's soft
+- resource limit on file size. *Note Limits on Resources::.

+----------------------
+-
+- These signals are used for various other purposes. In general, they
+-will not affect your program unless it explicitly uses them for
+-something.
+-
+- - Macro: int SIGUSR1
+- - Macro: int SIGUSR2
+- The `SIGUSR1' and `SIGUSR2' signals are set aside for you to use
+- any way you want. They're useful for simple interprocess
+- communication, if you write a signal handler for them in the
+- program that receives the signal.
+-
+- There is an example showing the use of `SIGUSR1' and `SIGUSR2' in
+- *Note Signaling Another Process::.
+-
+- The default action is to terminate the process.
+-
+- - Macro: int SIGWINCH
+- Window size change. This is generated on some systems (including
+- GNU) when the terminal driver's record of the number of rows and
+- columns on the screen is changed. The default action is to ignore
+- it.
+-
+- If a program does full-screen display, it should handle `SIGWINCH'.
+- When the signal arrives, it should fetch the new screen size and
+- reformat its display accordingly.
+-
+- - Macro: int SIGINFO
+- Information request. In 4.4 BSD and the GNU system, this signal
+- is sent to all the processes in the foreground process group of
+- the controlling terminal when the user types the STATUS character
+- in canonical mode; *note Signal Characters::.
+-
+- If the process is the leader of the process group, the default
+- action is to print some status information about the system and
+- what the process is doing. Otherwise the default is to do nothing.

+-Signal Messages
+----------------
+-
+- We mentioned above that the shell prints a message describing the
+-signal that terminated a child process. The clean way to print a
+-message describing a signal is to use the functions `strsignal' and
+-`psignal'. These functions use a signal number to specify which kind
+-of signal to describe. The signal number may come from the termination
+-status of a child process (*note Process Completion::) or it may come
+-from a signal handler in the same process.
+-
+- - Function: char * strsignal (int SIGNUM)
+- This function returns a pointer to a statically-allocated string
+- containing a message describing the signal SIGNUM. You should not
+- modify the contents of this string; and, since it can be rewritten
+- on subsequent calls, you should save a copy of it if you need to
+- reference it later.
+-
+- This function is a GNU extension, declared in the header file
+- `string.h'.
+-
+- - Function: void psignal (int SIGNUM, const char *MESSAGE)
+- This function prints a message describing the signal SIGNUM to the
+- standard error output stream `stderr'; see *Note Standard
+- Streams::.
+-
+- If you call `psignal' with a MESSAGE that is either a null pointer
+- or an empty string, `psignal' just prints the message
+- corresponding to SIGNUM, adding a trailing newline.
+-
+- If you supply a non-null MESSAGE argument, then `psignal' prefixes
+- its output with this string. It adds a colon and a space
+- character to separate the MESSAGE from the string corresponding to
+- SIGNUM.
+-
+- This function is a BSD feature, declared in the header file
+- `signal.h'.
+-
+- There is also an array `sys_siglist' which contains the messages for
+-the various signal codes. This array exists on BSD systems, unlike
+-`strsignal'.

+-=========================

+-
+-Basic Signal Handling
+----------------------
+-
+- The `signal' function provides a simple interface for establishing
+-an action for a particular signal. The function and associated macros
+-are declared in the header file `signal.h'.
+-
+- - Data Type: sighandler_t
+- This is the type of signal handler functions. Signal handlers
+- take one integer argument specifying the signal number, and have
+- return type `void'. So, you should define handler functions like
+- this:
+-
+- void HANDLER (int `signum') { ... }
+-
+- The name `sighandler_t' for this data type is a GNU extension.
+-
+- - Function: sighandler_t signal (int SIGNUM, sighandler_t ACTION)
+- The `signal' function establishes ACTION as the action for the
+- signal SIGNUM.
+-
+- The first argument, SIGNUM, identifies the signal whose behavior
+- you want to control, and should be a signal number. The proper
+- way to specify a signal number is with one of the symbolic signal
+- names (*note Standard Signals::)--don't use an explicit number,
+- because the numerical code for a given kind of signal may vary
+- from operating system to operating system.
+-
+- The second argument, ACTION, specifies the action to use for the
+- signal SIGNUM. This can be one of the following:
+-
+- `SIG_DFL'
+- `SIG_DFL' specifies the default action for the particular
+- signal. The default actions for various kinds of signals are
+- stated in *Note Standard Signals::.
+-
+- `SIG_IGN'
+- `SIG_IGN' specifies that the signal should be ignored.
+-
+- Your program generally should not ignore signals that
+- represent serious events or that are normally used to request
+- termination. You cannot ignore the `SIGKILL' or `SIGSTOP'
+- signals at all. You can ignore program error signals like
+- `SIGSEGV', but ignoring the error won't enable the program to
+- continue executing meaningfully. Ignoring user requests such
+- as `SIGINT', `SIGQUIT', and `SIGTSTP' is unfriendly.
+-
+- When you do not wish signals to be delivered during a certain
+- part of the program, the thing to do is to block them, not
+- ignore them. *Note Blocking Signals::.
+-
+- `HANDLER'
+- Supply the address of a handler function in your program, to
+- specify running this handler as the way to deliver the signal.
+-
+- For more information about defining signal handler functions,
+- see *Note Defining Handlers::.
+-
+- If you set the action for a signal to `SIG_IGN', or if you set it
+- to `SIG_DFL' and the default action is to ignore that signal, then
+- any pending signals of that type are discarded (even if they are
+- blocked). Discarding the pending signals means that they will
+- never be delivered, not even if you subsequently specify another
+- action and unblock this kind of signal.
+-
+- The `signal' function returns the action that was previously in
+- effect for the specified SIGNUM. You can save this value and
+- restore it later by calling `signal' again.
+-
+- If `signal' can't honor the request, it returns `SIG_ERR' instead.
+- The following `errno' error conditions are defined for this
+- function:
+-
+- `EINVAL'
+- You specified an invalid SIGNUM; or you tried to ignore or
+- provide a handler for `SIGKILL' or `SIGSTOP'.
+-
+- *Compatibility Note:* A problem encountered when working with the
+-`signal' function is that it has different semantics on BSD and SVID
+-systems. The difference is that on SVID systems the signal handler is
+-deinstalled after signal delivery. On BSD systems the handler must be
+-explicitly deinstalled. In the GNU C Library we use the BSD version by
+-default. To use the SVID version you can either use the function
+-`sysv_signal' (see below) or use the `_XOPEN_SOURCE' feature select
+-macro (*note Feature Test Macros::). In general, use of these
+-functions should be avoided because of compatibility problems. It is
+-better to use `sigaction' if it is available since the results are much
+-more reliable.
+-
+- Here is a simple example of setting up a handler to delete temporary
+-files when certain fatal signals happen:
+-
+- #include <signal.h>
+-
+- void
+- termination_handler (int signum)
+- {
+- struct temp_file *p;
+-
+- for (p = temp_file_list; p; p = p->next)
+- unlink (p->name);
+- }
+-
+- int
+- main (void)
+- {
+- ...
+- if (signal (SIGINT, termination_handler) == SIG_IGN)
+- signal (SIGINT, SIG_IGN);
+- if (signal (SIGHUP, termination_handler) == SIG_IGN)
+- signal (SIGHUP, SIG_IGN);
+- if (signal (SIGTERM, termination_handler) == SIG_IGN)
+- signal (SIGTERM, SIG_IGN);
+- ...
+- }
+-
+-Note that if a given signal was previously set to be ignored, this code
+-avoids altering that setting. This is because non-job-control shells
+-often ignore certain signals when starting children, and it is important
+-for the children to respect this.
+-
+- We do not handle `SIGQUIT' or the program error signals in this
+-example because these are designed to provide information for debugging
+-(a core dump), and the temporary files may give useful information.
+-
+- - Function: sighandler_t sysv_signal (int SIGNUM, sighandler_t ACTION)
+- The `sysv_signal' implements the behavior of the standard `signal'
+- function as found on SVID systems. The difference to BSD systems
+- is that the handler is deinstalled after a delivery of a signal.
+-
+- *Compatibility Note:* As said above for `signal', this function
+- should be avoided when possible. `sigaction' is the preferred
+- method.
+-
+- - Function: sighandler_t ssignal (int SIGNUM, sighandler_t ACTION)
+- The `ssignal' function does the same thing as `signal'; it is
+- provided only for compatibility with SVID.
+-
+- - Macro: sighandler_t SIG_ERR
+- The value of this macro is used as the return value from `signal'
+- to indicate an error.

+-
+-Advanced Signal Handling
+-------------------------
+-
+- The `sigaction' function has the same basic effect as `signal': to
+-specify how a signal should be handled by the process. However,
+-`sigaction' offers more control, at the expense of more complexity. In
+-particular, `sigaction' allows you to specify additional flags to
+-control when the signal is generated and how the handler is invoked.
+-
+- The `sigaction' function is declared in `signal.h'.
+-
+- - Data Type: struct sigaction
+- Structures of type `struct sigaction' are used in the `sigaction'
+- function to specify all the information about how to handle a
+- particular signal. This structure contains at least the following
+- members:
+-
+- `sighandler_t sa_handler'
+- This is used in the same way as the ACTION argument to the
+- `signal' function. The value can be `SIG_DFL', `SIG_IGN', or
+- a function pointer. *Note Basic Signal Handling::.
+-
+- `sigset_t sa_mask'
+- This specifies a set of signals to be blocked while the
+- handler runs. Blocking is explained in *Note Blocking for
+- Handler::. Note that the signal that was delivered is
+- automatically blocked by default before its handler is
+- started; this is true regardless of the value in `sa_mask'.
+- If you want that signal not to be blocked within its handler,
+- you must write code in the handler to unblock it.
+-
+- `int sa_flags'
+- This specifies various flags which can affect the behavior of
+- the signal. These are described in more detail in *Note
+- Flags for Sigaction::.
+-
+- - Function: int sigaction (int SIGNUM, const struct sigaction
+- *restrict ACTION, struct sigaction *restrict OLD-ACTION)
+- The ACTION argument is used to set up a new action for the signal
+- SIGNUM, while the OLD-ACTION argument is used to return
+- information about the action previously associated with this
+- symbol. (In other words, OLD-ACTION has the same purpose as the
+- `signal' function's return value--you can check to see what the
+- old action in effect for the signal was, and restore it later if
+- you want.)
+-
+- Either ACTION or OLD-ACTION can be a null pointer. If OLD-ACTION
+- is a null pointer, this simply suppresses the return of
+- information about the old action. If ACTION is a null pointer,
+- the action associated with the signal SIGNUM is unchanged; this
+- allows you to inquire about how a signal is being handled without
+- changing that handling.
+-
+- The return value from `sigaction' is zero if it succeeds, and `-1'
+- on failure. The following `errno' error conditions are defined
+- for this function:
+-
+- `EINVAL'
+- The SIGNUM argument is not valid, or you are trying to trap
+- or ignore `SIGKILL' or `SIGSTOP'.
+-
+-\1f
+-File: libc.info, Node: Signal and Sigaction, Next: Sigaction Function Example, Prev: Advanced Signal Handling, Up: Signal Actions
+-
+-Interaction of `signal' and `sigaction'
+----------------------------------------
+-
+- It's possible to use both the `signal' and `sigaction' functions
+-within a single program, but you have to be careful because they can
+-interact in slightly strange ways.
+-
+- The `sigaction' function specifies more information than the
+-`signal' function, so the return value from `signal' cannot express the
+-full range of `sigaction' possibilities. Therefore, if you use
+-`signal' to save and later reestablish an action, it may not be able to
+-reestablish properly a handler that was established with `sigaction'.
+-
+- To avoid having problems as a result, always use `sigaction' to save
+-and restore a handler if your program uses `sigaction' at all. Since
+-`sigaction' is more general, it can properly save and reestablish any
+-action, regardless of whether it was established originally with
+-`signal' or `sigaction'.
+-
+- On some systems if you establish an action with `signal' and then
+-examine it with `sigaction', the handler address that you get may not
+-be the same as what you specified with `signal'. It may not even be
+-suitable for use as an action argument with `signal'. But you can rely
+-on using it as an argument to `sigaction'. This problem never happens
+-on the GNU system.
+-
+- So, you're better off using one or the other of the mechanisms
+-consistently within a single program.
+-
+- *Portability Note:* The basic `signal' function is a feature of
+-ISO C, while `sigaction' is part of the POSIX.1 standard. If you are
+-concerned about portability to non-POSIX systems, then you should use
+-the `signal' function instead.

+-
+-`sigaction' Function Example
+-----------------------------
+-
+- In *Note Basic Signal Handling::, we gave an example of establishing
+-a simple handler for termination signals using `signal'. Here is an
+-equivalent example using `sigaction':
+-
+- #include <signal.h>
+-
+- void
+- termination_handler (int signum)
+- {
+- struct temp_file *p;
+-
+- for (p = temp_file_list; p; p = p->next)
+- unlink (p->name);
+- }
+-
+- int
+- main (void)
+- {
+- ...
+- struct sigaction new_action, old_action;
+-
+- /* Set up the structure to specify the new action. */
+- new_action.sa_handler = termination_handler;
+- sigemptyset (&new_action.sa_mask);
+- new_action.sa_flags = 0;
+-
+- sigaction (SIGINT, NULL, &old_action);
+- if (old_action.sa_handler != SIG_IGN)
+- sigaction (SIGINT, &new_action, NULL);
+- sigaction (SIGHUP, NULL, &old_action);
+- if (old_action.sa_handler != SIG_IGN)
+- sigaction (SIGHUP, &new_action, NULL);
+- sigaction (SIGTERM, NULL, &old_action);
+- if (old_action.sa_handler != SIG_IGN)
+- sigaction (SIGTERM, &new_action, NULL);
+- ...
+- }
+-
+- The program just loads the `new_action' structure with the desired
+-parameters and passes it in the `sigaction' call. The usage of
+-`sigemptyset' is described later; see *Note Blocking Signals::.
+-
+- As in the example using `signal', we avoid handling signals
+-previously set to be ignored. Here we can avoid altering the signal
+-handler even momentarily, by using the feature of `sigaction' that lets
+-us examine the current action without specifying a new one.
+-
+- Here is another example. It retrieves information about the current
+-action for `SIGINT' without changing that action.
+-
+- struct sigaction query_action;
+-
+- if (sigaction (SIGINT, NULL, &query_action) < 0)
+- /* `sigaction' returns -1 in case of error. */
+- else if (query_action.sa_handler == SIG_DFL)
+- /* `SIGINT' is handled in the default, fatal manner. */
+- else if (query_action.sa_handler == SIG_IGN)
+- /* `SIGINT' is ignored. */
+- else
+- /* A programmer-defined signal handler is in effect. */

+-
+-Flags for `sigaction'
+----------------------
+-
+- The `sa_flags' member of the `sigaction' structure is a catch-all
+-for special features. Most of the time, `SA_RESTART' is a good value
+-to use for this field.
+-
+- The value of `sa_flags' is interpreted as a bit mask. Thus, you
+-should choose the flags you want to set, OR those flags together, and
+-store the result in the `sa_flags' member of your `sigaction' structure.
+-
+- Each signal number has its own set of flags. Each call to
+-`sigaction' affects one particular signal number, and the flags that
+-you specify apply only to that particular signal.
+-
+- In the GNU C library, establishing a handler with `signal' sets all
+-the flags to zero except for `SA_RESTART', whose value depends on the
+-settings you have made with `siginterrupt'. *Note Interrupted
+-Primitives::, to see what this is about.
+-
+- These macros are defined in the header file `signal.h'.
+-
+- - Macro: int SA_NOCLDSTOP
+- This flag is meaningful only for the `SIGCHLD' signal. When the
+- flag is set, the system delivers the signal for a terminated child
+- process but not for one that is stopped. By default, `SIGCHLD' is
+- delivered for both terminated children and stopped children.
+-
+- Setting this flag for a signal other than `SIGCHLD' has no effect.
+-
+- - Macro: int SA_ONSTACK
+- If this flag is set for a particular signal number, the system
+- uses the signal stack when delivering that kind of signal. *Note
+- Signal Stack::. If a signal with this flag arrives and you have
+- not set a signal stack, the system terminates the program with
+- `SIGILL'.
+-
+- - Macro: int SA_RESTART
+- This flag controls what happens when a signal is delivered during
+- certain primitives (such as `open', `read' or `write'), and the
+- signal handler returns normally. There are two alternatives: the
+- library function can resume, or it can return failure with error
+- code `EINTR'.
+-
+- The choice is controlled by the `SA_RESTART' flag for the
+- particular kind of signal that was delivered. If the flag is set,
+- returning from a handler resumes the library function. If the
+- flag is clear, returning from a handler makes the function fail.
+- *Note Interrupted Primitives::.

+-
+-Initial Signal Actions
+-----------------------
+-
+- When a new process is created (*note Creating a Process::), it
+-inherits handling of signals from its parent process. However, when
+-you load a new process image using the `exec' function (*note Executing
+-a File::), any signals that you've defined your own handlers for revert
+-to their `SIG_DFL' handling. (If you think about it a little, this
+-makes sense; the handler functions from the old program are specific to
+-that program, and aren't even present in the address space of the new
+-program image.) Of course, the new program can establish its own
+-handlers.
+-
+- When a program is run by a shell, the shell normally sets the initial
+-actions for the child process to `SIG_DFL' or `SIG_IGN', as
+-appropriate. It's a good idea to check to make sure that the shell has
+-not set up an initial action of `SIG_IGN' before you establish your own
+-signal handlers.
+-
+- Here is an example of how to establish a handler for `SIGHUP', but
+-not if `SIGHUP' is currently ignored:
+-
+- ...
+- struct sigaction temp;
+-
+- sigaction (SIGHUP, NULL, &temp);
+-
+- if (temp.sa_handler != SIG_IGN)
+- {
+- temp.sa_handler = handle_sighup;

+-Defining Signal Handlers
+-========================
+-
+- This section describes how to write a signal handler function that
+-can be established with the `signal' or `sigaction' functions.
+-
+- A signal handler is just a function that you compile together with
+-the rest of the program. Instead of directly invoking the function,
+-you use `signal' or `sigaction' to tell the operating system to call it
+-when a signal arrives. This is known as "establishing" the handler.
+-*Note Signal Actions::.
+-
+- There are two basic strategies you can use in signal handler
+-functions:
+-
+- * You can have the handler function note that the signal arrived by
+- tweaking some global data structures, and then return normally.
+-
+- * You can have the handler function terminate the program or transfer
+- control to a point where it can recover from the situation that
+- caused the signal.
+-
+- You need to take special care in writing handler functions because
+-they can be called asynchronously. That is, a handler might be called
+-at any point in the program, unpredictably. If two signals arrive
+-during a very short interval, one handler can run within another. This
+-section describes what your handler should do, and what you should
+-avoid.

+-
+-* Handler Returns:: Handlers that return normally, and what
+- this means.
+-* Termination in Handler:: How handler functions terminate a program.
+-* Longjmp in Handler:: Nonlocal transfer of control out of a
+- signal handler.
+-* Signals in Handler:: What happens when signals arrive while
+- the handler is already occupied.
+-* Merged Signals:: When a second signal arrives before the
+- first is handled.
+-* Nonreentrancy:: Do not call any functions unless you know they
+- are reentrant with respect to signals.
+-* Atomic Data Access:: A single handler can run in the middle of
+- reading or writing a single object.

+-
+-Signal Handlers that Return
+----------------------------
+-
+- Handlers which return normally are usually used for signals such as
+-`SIGALRM' and the I/O and interprocess communication signals. But a
+-handler for `SIGINT' might also return normally after setting a flag
+-that tells the program to exit at a convenient time.
+-
+- It is not safe to return normally from the handler for a program
+-error signal, because the behavior of the program when the handler
+-function returns is not defined after a program error. *Note Program
+-Error Signals::.
+-
+- Handlers that return normally must modify some global variable in
+-order to have any effect. Typically, the variable is one that is
+-examined periodically by the program during normal operation. Its data
+-type should be `sig_atomic_t' for reasons described in *Note Atomic
+-Data Access::.
+-
+- Here is a simple example of such a program. It executes the body of
+-the loop until it has noticed that a `SIGALRM' signal has arrived.
+-This technique is useful because it allows the iteration in progress
+-when the signal arrives to complete before the loop exits.
+-
+- #include <signal.h>
+- #include <stdio.h>
+- #include <stdlib.h>
+-
+- /* This flag controls termination of the main loop. */
+- volatile sig_atomic_t keep_going = 1;
+-
+- /* The signal handler just clears the flag and re-enables itself. */

+- {
+- keep_going = 0;

+- /* Establish a handler for SIGALRM signals. */

+- /* Set an alarm to go off in a little while. */

+-
+-Handlers That Terminate the Process
+------------------------------------
+-
+- Handler functions that terminate the program are typically used to
+-cause orderly cleanup or recovery from program error signals and
+-interactive interrupts.
+-
+- The cleanest way for a handler to terminate the process is to raise
+-the same signal that ran the handler in the first place. Here is how
+-to do this:
+-
+- volatile sig_atomic_t fatal_error_in_progress = 0;
+-
+- void
+- fatal_error_signal (int sig)
+- {
+- /* Since this handler is established for more than one kind of signal,
+- it might still get invoked recursively by delivery of some other kind
+- of signal. Use a static variable to keep track of that. */
+- if (fatal_error_in_progress)
+- raise (sig);
+- fatal_error_in_progress = 1;
+-
+- /* Now do the clean up actions:
+- - reset terminal modes
+- - kill child processes
+- - remove lock files */
+- ...
+-
+- /* Now reraise the signal. We reactivate the signal's
+- default handling, which is to terminate the process.
+- We could just call `exit' or `abort',
+- but reraising the signal sets the return status
+- from the process correctly. */
+- signal (sig, SIG_DFL);
+- raise (sig);
+- }
+-
+-\1f
+-File: libc.info, Node: Longjmp in Handler, Next: Signals in Handler, Prev: Termination in Handler, Up: Defining Handlers
+-
+-Nonlocal Control Transfer in Handlers
+--------------------------------------
+-
+- You can do a nonlocal transfer of control out of a signal handler
+-using the `setjmp' and `longjmp' facilities (*note Non-Local Exits::).
+-
+- When the handler does a nonlocal control transfer, the part of the
+-program that was running will not continue. If this part of the program
+-was in the middle of updating an important data structure, the data
+-structure will remain inconsistent. Since the program does not
+-terminate, the inconsistency is likely to be noticed later on.
+-
+- There are two ways to avoid this problem. One is to block the signal
+-for the parts of the program that update important data structures.
+-Blocking the signal delays its delivery until it is unblocked, once the
+-critical updating is finished. *Note Blocking Signals::.
+-
+- The other way to re-initialize the crucial data structures in the
+-signal handler, or make their values consistent.
+-
+- Here is a rather schematic example showing the reinitialization of
+-one global variable.
+-
+- #include <signal.h>
+- #include <setjmp.h>
+-
+- jmp_buf return_to_top_level;
+-
+- volatile sig_atomic_t waiting_for_input;
+-
+- void
+- handle_sigint (int signum)

+- /* We may have been waiting for input when the signal arrived,
+- but we are no longer waiting once we transfer control. */

+-Freeing Memory Allocated with `malloc'
+-......................................
+-
+- When you no longer need a block that you got with `malloc', use the
+-function `free' to make the block available to be allocated again. The
+-prototype for this function is in `stdlib.h'.
+-
+- - Function: void free (void *PTR)
+- The `free' function deallocates the block of memory pointed at by
+- PTR.
+-
+- - Function: void cfree (void *PTR)
+- This function does the same thing as `free'. It's provided for
+- backward compatibility with SunOS; you should use `free' instead.
+-
+- Freeing a block alters the contents of the block. *Do not expect to
+-find any data (such as a pointer to the next block in a chain of
+-blocks) in the block after freeing it.* Copy whatever you need out of
+-the block before freeing it! Here is an example of the proper way to
+-free all the blocks in a chain, and the strings that they point to:
+-
+- struct chain
+- {
+- struct chain *next;
+- char *name;
+- }
+-
+- void
+- free_chain (struct chain *chain)
+- {
+- while (chain != 0)
+- {
+- struct chain *next = chain->next;
+- free (chain->name);
+- free (chain);
+- chain = next;
+- }
+- }
+-
+- Occasionally, `free' can actually return memory to the operating
+-system and make the process smaller. Usually, all it can do is allow a
+-later call to `malloc' to reuse the space. In the meantime, the space
+-remains in your program as part of a free-list used internally by
+-`malloc'.

+-terminates.

+-
+-Changing the Size of a Block
+-............................
+-
+- Often you do not know for certain how big a block you will
+-ultimately need at the time you must begin to use the block. For
+-example, the block might be a buffer that you use to hold a line being
+-read from a file; no matter how long you make the buffer initially, you
+-may encounter a line that is longer.
+-
+- You can make the block longer by calling `realloc'. This function
+-is declared in `stdlib.h'.
+-
+- - Function: void * realloc (void *PTR, size_t NEWSIZE)
+- The `realloc' function changes the size of the block whose address
+- is PTR to be NEWSIZE.
+-
+- Since the space after the end of the block may be in use, `realloc'
+- may find it necessary to copy the block to a new address where
+- more free space is available. The value of `realloc' is the new
+- address of the block. If the block needs to be moved, `realloc'
+- copies the old contents.
+-
+- If you pass a null pointer for PTR, `realloc' behaves just like
+- `malloc (NEWSIZE)'. This can be convenient, but beware that older
+- implementations (before ISO C) may not support this behavior, and
+- will probably crash when `realloc' is passed a null pointer.
+-
+- Like `malloc', `realloc' may return a null pointer if no memory
+-space is available to make the block bigger. When this happens, the
+-original block is untouched; it has not been modified or relocated.
+-
+- In most cases it makes no difference what happens to the original
+-block when `realloc' fails, because the application program cannot
+-continue when it is out of memory, and the only thing to do is to give
+-a fatal error message. Often it is convenient to write and use a
+-subroutine, conventionally called `xrealloc', that takes care of the
+-error message as `xmalloc' does for `malloc':
+-
+- void *
+- xrealloc (void *ptr, size_t size)
+- {
+- register void *value = realloc (ptr, size);
+- if (value == 0)
+- fatal ("Virtual memory exhausted");
+- return value;
+- }
+-
+- You can also use `realloc' to make a block smaller. The reason you
+-would do this is to avoid tying up a lot of memory space when only a
+-little is needed. In several allocation implementations, making a
+-block smaller sometimes necessitates copying it, so it can fail if no
+-other space is available.
+-
+- If the new size you specify is the same as the old size, `realloc'
+-is guaranteed to change nothing and return the same address that you
+-gave.

+-Allocating Cleared Space
+-........................
+-
+- The function `calloc' allocates memory and clears it to zero. It is
+-declared in `stdlib.h'.
+-
+- - Function: void * calloc (size_t COUNT, size_t ELTSIZE)
+- This function allocates a block long enough to contain a vector of
+- COUNT elements, each of size ELTSIZE. Its contents are cleared to
+- zero before `calloc' returns.
+-
+- You could define `calloc' as follows:
+-
+- void *
+- calloc (size_t count, size_t eltsize)
+- {
+- size_t size = count * eltsize;
+- void *value = malloc (size);
+- if (value != 0)
+- memset (value, 0, size);
+- return value;
+- }
+-
+- But in general, it is not guaranteed that `calloc' calls `malloc'
+-internally. Therefore, if an application provides its own
+-`malloc'/`realloc'/`free' outside the C library, it should always
+-define `calloc', too.

+-Efficiency Considerations for `malloc'
+-......................................
+-
+- As opposed to other versions, the `malloc' in the GNU C Library does
+-not round up block sizes to powers of two, neither for large nor for
+-small sizes. Neighboring chunks can be coalesced on a `free' no matter
+-what their size is. This makes the implementation suitable for all
+-kinds of allocation patterns without generally incurring high memory
+-waste through fragmentation.
+-
+- Very large blocks (much larger than a page) are allocated with
+-`mmap' (anonymous or via `/dev/zero') by this implementation. This has
+-the great advantage that these chunks are returned to the system
+-immediately when they are freed. Therefore, it cannot happen that a
+-large chunk becomes "locked" in between smaller ones and even after
+-calling `free' wastes memory. The size threshold for `mmap' to be used
+-can be adjusted with `mallopt'. The use of `mmap' can also be disabled
+-completely.

+-
+-Allocating Aligned Memory Blocks
+-................................
+-
+- The address of a block returned by `malloc' or `realloc' in the GNU
+-system is always a multiple of eight (or sixteen on 64-bit systems).
+-If you need a block whose address is a multiple of a higher power of
+-two than that, use `memalign', `posix_memalign', or `valloc'.
+-`memalign' is declared in `malloc.h' and `posix_memalign' is declared
+-in `stdlib.h'.
+-
+- With the GNU library, you can use `free' to free the blocks that
+-`memalign', `posix_memalign', and `valloc' return. That does not work
+-in BSD, however--BSD does not provide any way to free such blocks.
+-
+- - Function: void * memalign (size_t BOUNDARY, size_t SIZE)
+- The `memalign' function allocates a block of SIZE bytes whose
+- address is a multiple of BOUNDARY. The BOUNDARY must be a power
+- of two! The function `memalign' works by allocating a somewhat
+- larger block, and then returning an address within the block that
+- is on the specified boundary.
+-
+- - Function: int posix_memalign (void **MEMPTR, size_t ALIGNMENT,
+- size_t SIZE)
+- The `posix_memalign' function is similar to the `memalign'
+- function in that it returns a buffer of SIZE bytes aligned to a
+- multiple of ALIGNMENT. But it adds one requirement to the
+- parameter ALIGNMENT: the value must be a power of two multiple of
+- `sizeof (void *)'.
+-
+- If the function succeeds in allocation memory a pointer to the
+- allocated memory is returned in `*MEMPTR' and the return value is
+- zero. Otherwise the function returns an error value indicating
+- the problem.
+-
+- This function was introduced in POSIX 1003.1d.
+-
+- - Function: void * valloc (size_t SIZE)
+- Using `valloc' is like using `memalign' and passing the page size
+- as the value of the second argument. It is implemented like this:
+-
+- void *
+- valloc (size_t size)
+- {
+- return memalign (getpagesize (), size);
+- }

+-Malloc Tunable Parameters
+-.........................
+-
+- You can adjust some parameters for dynamic memory allocation with the
+-`mallopt' function. This function is the general SVID/XPG interface,
+-defined in `malloc.h'.
+-
+- - Function: int mallopt (int PARAM, int VALUE)
+- When calling `mallopt', the PARAM argument specifies the parameter
+- to be set, and VALUE the new value to be set. Possible choices
+- for PARAM, as defined in `malloc.h', are:
+-
+- `M_TRIM_THRESHOLD'
+- This is the minimum size (in bytes) of the top-most,
+- releasable chunk that will cause `sbrk' to be called with a
+- negative argument in order to return memory to the system.
+-
+- `M_TOP_PAD'
+- This parameter determines the amount of extra memory to
+- obtain from the system when a call to `sbrk' is required. It
+- also specifies the number of bytes to retain when shrinking
+- the heap by calling `sbrk' with a negative argument. This
+- provides the necessary hysteresis in heap size such that
+- excessive amounts of system calls can be avoided.
+-
+- `M_MMAP_THRESHOLD'
+- All chunks larger than this value are allocated outside the
+- normal heap, using the `mmap' system call. This way it is
+- guaranteed that the memory for these chunks can be returned
+- to the system on `free'. Note that requests smaller than
+- this threshold might still be allocated via `mmap'.
+-
+- `M_MMAP_MAX'
+- The maximum number of chunks to allocate with `mmap'.
+- Setting this to zero disables all use of `mmap'.

+-
+-Heap Consistency Checking
+-.........................
+-
+- You can ask `malloc' to check the consistency of dynamic memory by
+-using the `mcheck' function. This function is a GNU extension,
+-declared in `mcheck.h'.
+-
+- - Function: int mcheck (void (*ABORTFN) (enum mcheck_status STATUS))
+- Calling `mcheck' tells `malloc' to perform occasional consistency
+- checks. These will catch things such as writing past the end of a
+- block that was allocated with `malloc'.
+-
+- The ABORTFN argument is the function to call when an inconsistency
+- is found. If you supply a null pointer, then `mcheck' uses a
+- default function which prints a message and calls `abort' (*note
+- Aborting a Program::). The function you supply is called with one
+- argument, which says what sort of inconsistency was detected; its
+- type is described below.
+-
+- It is too late to begin allocation checking once you have allocated
+- anything with `malloc'. So `mcheck' does nothing in that case.
+- The function returns `-1' if you call it too late, and `0'
+- otherwise (when it is successful).
+-
+- The easiest way to arrange to call `mcheck' early enough is to use
+- the option `-lmcheck' when you link your program; then you don't
+- need to modify your program source at all. Alternatively you
+- might use a debugger to insert a call to `mcheck' whenever the
+- program is started, for example these gdb commands will
+- automatically call `mcheck' whenever the program starts:
+-
+- (gdb) break main
+- Breakpoint 1, main (argc=2, argv=0xbffff964) at whatever.c:10
+- (gdb) command 1
+- Type commands for when breakpoint 1 is hit, one per line.
+- End with a line saying just "end".
+- >call mcheck(0)
+- >continue
+- >end
+- (gdb) ...
+-
+- This will however only work if no initialization function of any
+- object involved calls any of the `malloc' functions since `mcheck'
+- must be called before the first such function.
+-
+-
+- - Function: enum mcheck_status mprobe (void *POINTER)
+- The `mprobe' function lets you explicitly check for inconsistencies
+- in a particular allocated block. You must have already called
+- `mcheck' at the beginning of the program, to do its occasional
+- checks; calling `mprobe' requests an additional consistency check
+- to be done at the time of the call.
+-
+- The argument POINTER must be a pointer returned by `malloc' or
+- `realloc'. `mprobe' returns a value that says what inconsistency,
+- if any, was found. The values are described below.
+-
+- - Data Type: enum mcheck_status
+- This enumerated type describes what kind of inconsistency was
+- detected in an allocated block, if any. Here are the possible
+- values:
+-
+- `MCHECK_DISABLED'
+- `mcheck' was not called before the first allocation. No
+- consistency checking can be done.
+-
+- `MCHECK_OK'
+- No inconsistency detected.
+-
+- `MCHECK_HEAD'
+- The data immediately before the block was modified. This
+- commonly happens when an array index or pointer is
+- decremented too far.
+-
+- `MCHECK_TAIL'
+- The data immediately after the block was modified. This
+- commonly happens when an array index or pointer is
+- incremented too far.
+-
+- `MCHECK_FREE'
+- The block was already freed.
+-
+- Another possibility to check for and guard against bugs in the use of
+-`malloc', `realloc' and `free' is to set the environment variable
+-`MALLOC_CHECK_'. When `MALLOC_CHECK_' is set, a special (less
+-efficient) implementation is used which is designed to be tolerant
+-against simple errors, such as double calls of `free' with the same
+-argument, or overruns of a single byte (off-by-one bugs). Not all such
+-errors can be protected against, however, and memory leaks can result.
+-If `MALLOC_CHECK_' is set to `0', any detected heap corruption is
+-silently ignored; if set to `1', a diagnostic is printed on `stderr';
+-if set to `2', `abort' is called immediately. This can be useful
+-because otherwise a crash may happen much later, and the true cause for
+-the problem is then very hard to track down.
+-
+- There is one problem with `MALLOC_CHECK_': in SUID or SGID binaries
+-it could possibly be exploited since diverging from the normal programs
+-behavior it now writes something to the standard error descriptor.
+-Therefore the use of `MALLOC_CHECK_' is disabled by default for SUID
+-and SGID binaries. It can be enabled again by the system administrator
+-by adding a file `/etc/suid-debug' (the content is not important it
+-could be empty).
+-
+- So, what's the difference between using `MALLOC_CHECK_' and linking
+-with `-lmcheck'? `MALLOC_CHECK_' is orthogonal with respect to
+-`-lmcheck'. `-lmcheck' has been added for backward compatibility.
+-Both `MALLOC_CHECK_' and `-lmcheck' should uncover the same bugs - but
+-using `MALLOC_CHECK_' you don't need to recompile your application.

+-Memory Allocation Hooks
+-.......................
+-
+- The GNU C library lets you modify the behavior of `malloc',
+-`realloc', and `free' by specifying appropriate hook functions. You
+-can use these hooks to help you debug programs that use dynamic memory
+-allocation, for example.
+-
+- The hook variables are declared in `malloc.h'.
+-
+- - Variable: __malloc_hook
+- The value of this variable is a pointer to the function that
+- `malloc' uses whenever it is called. You should define this
+- function to look like `malloc'; that is, like:
+-
+- void *FUNCTION (size_t SIZE, const void *CALLER)
+-
+- The value of CALLER is the return address found on the stack when
+- the `malloc' function was called. This value allows you to trace
+- the memory consumption of the program.
+-
+- - Variable: __realloc_hook
+- The value of this variable is a pointer to function that `realloc'
+- uses whenever it is called. You should define this function to
+- look like `realloc'; that is, like:
+-
+- void *FUNCTION (void *PTR, size_t SIZE, const void *CALLER)
+-
+- The value of CALLER is the return address found on the stack when
+- the `realloc' function was called. This value allows you to trace
+- the memory consumption of the program.
+-
+- - Variable: __free_hook
+- The value of this variable is a pointer to function that `free'
+- uses whenever it is called. You should define this function to
+- look like `free'; that is, like:
+-
+- void FUNCTION (void *PTR, const void *CALLER)
+-
+- The value of CALLER is the return address found on the stack when
+- the `free' function was called. This value allows you to trace the
+- memory consumption of the program.
+-
+- - Variable: __memalign_hook
+- The value of this variable is a pointer to function that `memalign'
+- uses whenever it is called. You should define this function to
+- look like `memalign'; that is, like:
+-
+- void *FUNCTION (size_t ALIGNMENT, size_t SIZE, const void *CALLER)
+-
+- The value of CALLER is the return address found on the stack when
+- the `memalign' function was called. This value allows you to
+- trace the memory consumption of the program.
+-
+- You must make sure that the function you install as a hook for one of
+-these functions does not call that function recursively without
+-restoring the old value of the hook first! Otherwise, your program
+-will get stuck in an infinite recursion. Before calling the function
+-recursively, one should make sure to restore all the hooks to their
+-previous value. When coming back from the recursive call, all the
+-hooks should be resaved since a hook might modify itself.
+-
+- - Variable: __malloc_initialize_hook
+- The value of this variable is a pointer to a function that is
+- called once when the malloc implementation is initialized. This
+- is a weak variable, so it can be overridden in the application
+- with a definition like the following:
+-
+- void (*__MALLOC_INITIALIZE_HOOK) (void) = my_init_hook;
+-
+- An issue to look out for is the time at which the malloc hook
+-functions can be safely installed. If the hook functions call the
+-malloc-related functions recursively, it is necessary that malloc has
+-already properly initialized itself at the time when `__malloc_hook'
+-etc. is assigned to. On the other hand, if the hook functions provide a
+-complete malloc implementation of their own, it is vital that the hooks
+-are assigned to _before_ the very first `malloc' call has completed,
+-because otherwise a chunk obtained from the ordinary, un-hooked malloc
+-may later be handed to `__free_hook', for example.
+-
+- In both cases, the problem can be solved by setting up the hooks from
+-within a user-defined function pointed to by
+-`__malloc_initialize_hook'--then the hooks will be set up safely at the
+-right time.
+-
+- Here is an example showing how to use `__malloc_hook' and
+-`__free_hook' properly. It installs a function that prints out
+-information every time `malloc' or `free' is called. We just assume
+-here that `realloc' and `memalign' are not used in our program.
+-

+-Allocation Debugging
+---------------------
+-
+- A complicated task when programming with languages which do not use
+-garbage collected dynamic memory allocation is to find memory leaks.
+-Long running programs must assure that dynamically allocated objects are
+-freed at the end of their lifetime. If this does not happen the system
+-runs out of memory, sooner or later.
+-
+- The `malloc' implementation in the GNU C library provides some
+-simple means to detect such leaks and obtain some information to find
+-the location. To do this the application must be started in a special
+-mode which is enabled by an environment variable. There are no speed
+-penalties for the program if the debugging mode is not enabled.

+-How to install the tracing functionality
+-........................................
+-
+- - Function: void mtrace (void)
+- When the `mtrace' function is called it looks for an environment
+- variable named `MALLOC_TRACE'. This variable is supposed to
+- contain a valid file name. The user must have write access. If
+- the file already exists it is truncated. If the environment
+- variable is not set or it does not name a valid file which can be
+- opened for writing nothing is done. The behavior of `malloc' etc.
+- is not changed. For obvious reasons this also happens if the
+- application is installed with the SUID or SGID bit set.
+-
+- If the named file is successfully opened, `mtrace' installs special
+- handlers for the functions `malloc', `realloc', and `free' (*note
+- Hooks for Malloc::). From then on, all uses of these functions
+- are traced and protocolled into the file. There is now of course
+- a speed penalty for all calls to the traced functions so tracing
+- should not be enabled during normal use.
+-
+- This function is a GNU extension and generally not available on
+- other systems. The prototype can be found in `mcheck.h'.
+-
+- - Function: void muntrace (void)
+- The `muntrace' function can be called after `mtrace' was used to
+- enable tracing the `malloc' calls. If no (successful) call of
+- `mtrace' was made `muntrace' does nothing.
+-
+- Otherwise it deinstalls the handlers for `malloc', `realloc', and
+- `free' and then closes the protocol file. No calls are
+- protocolled anymore and the program runs again at full speed.
+-
+- This function is a GNU extension and generally not available on
+- other systems. The prototype can be found in `mcheck.h'.

+-
+-Example program excerpts
+-........................
+-
+- Even though the tracing functionality does not influence the runtime
+-behavior of the program it is not a good idea to call `mtrace' in all
+-programs. Just imagine that you debug a program using `mtrace' and all
+-other programs used in the debugging session also trace their `malloc'
+-calls. The output file would be the same for all programs and thus is
+-unusable. Therefore one should call `mtrace' only if compiled for
+-debugging. A program could therefore start like this:
+-
+- #include <mcheck.h>
+-
+- int
+- main (int argc, char *argv[])
+- {
+- #ifdef DEBUGGING
+- mtrace ();
+- #endif
+- ...
+- }
+-
+- This is all what is needed if you want to trace the calls during the
+-whole runtime of the program. Alternatively you can stop the tracing at
+-any time with a call to `muntrace'. It is even possible to restart the
+-tracing again with a new call to `mtrace'. But this can cause
+-unreliable results since there may be calls of the functions which are
+-not called. Please note that not only the application uses the traced
+-functions, also libraries (including the C library itself) use these
+-functions.
+-
+- This last point is also why it is no good idea to call `muntrace'
+-before the program terminated. The libraries are informed about the
+-termination of the program only after the program returns from `main'
+-or calls `exit' and so cannot free the memory they use before this time.
+-
+- So the best thing one can do is to call `mtrace' as the very first
+-function in the program and never call `muntrace'. So the program
+-traces almost all uses of the `malloc' functions (except those calls
+-which are executed by constructors of the program or used libraries).

+-
+-Some more or less clever ideas
+-..............................
+-
+- You know the situation. The program is prepared for debugging and in
+-all debugging sessions it runs well. But once it is started without
+-debugging the error shows up. A typical example is a memory leak that
+-becomes visible only when we turn off the debugging. If you foresee
+-such situations you can still win. Simply use something equivalent to
+-the following little program:
+-
+- #include <mcheck.h>
+- #include <signal.h>
+-
+- static void
+- enable (int sig)
+- {
+- mtrace ();
+- signal (SIGUSR1, enable);
+- }
+-
+- static void
+- disable (int sig)
+- {
+- muntrace ();
+- signal (SIGUSR2, disable);
+- }
+-
+- int
+- main (int argc, char *argv[])
+- {
+- ...
+-
+- signal (SIGUSR1, enable);
+- signal (SIGUSR2, disable);
+-
+- ...
+- }
+-
+- I.e., the user can start the memory debugger any time s/he wants if
+-the program was started with `MALLOC_TRACE' set in the environment.
+-The output will of course not show the allocations which happened before
+-the first signal but if there is a memory leak this will show up
+-nevertheless.
+-
+-\1f
+-File: libc.info, Node: Interpreting the traces, Prev: Tips for the Memory Debugger, Up: Allocation Debugging
+-
+-Interpreting the traces
+-.......................
+-
+- If you take a look at the output it will look similar to this:
+-
+- = Start
+- [0x8048209] - 0x8064cc8
+- [0x8048209] - 0x8064ce0
+- [0x8048209] - 0x8064cf8
+- [0x80481eb] + 0x8064c48 0x14
+- [0x80481eb] + 0x8064c60 0x14
+- [0x80481eb] + 0x8064c78 0x14
+- [0x80481eb] + 0x8064c90 0x14
+- = End
+-
+- What this all means is not really important since the trace file is
+-not meant to be read by a human. Therefore no attention is given to
+-readability. Instead there is a program which comes with the GNU C
+-library which interprets the traces and outputs a summary in an
+-user-friendly way. The program is called `mtrace' (it is in fact a
+-Perl script) and it takes one or two arguments. In any case the name of
+-the file with the trace output must be specified. If an optional
+-argument precedes the name of the trace file this must be the name of
+-the program which generated the trace.
+-
+- drepper$ mtrace tst-mtrace log
+- No memory leaks.
+-
+- In this case the program `tst-mtrace' was run and it produced a
+-trace file `log'. The message printed by `mtrace' shows there are no
+-problems with the code, all allocated memory was freed afterwards.
+-
+- If we call `mtrace' on the example trace given above we would get a
+-different outout:
+-
+- drepper$ mtrace errlog
+- - 0x08064cc8 Free 2 was never alloc'd 0x8048209
+- - 0x08064ce0 Free 3 was never alloc'd 0x8048209
+- - 0x08064cf8 Free 4 was never alloc'd 0x8048209
+-
+- Memory not freed:
+- -----------------
+- Address Size Caller
+- 0x08064c48 0x14 at 0x80481eb
+- 0x08064c60 0x14 at 0x80481eb
+- 0x08064c78 0x14 at 0x80481eb
+- 0x08064c90 0x14 at 0x80481eb
+-
+- We have called `mtrace' with only one argument and so the script has
+-no chance to find out what is meant with the addresses given in the
+-trace. We can do better:
+-
+- drepper$ mtrace tst errlog
+- - 0x08064cc8 Free 2 was never alloc'd /home/drepper/tst.c:39
+- - 0x08064ce0 Free 3 was never alloc'd /home/drepper/tst.c:39
+- - 0x08064cf8 Free 4 was never alloc'd /home/drepper/tst.c:39
+-
+- Memory not freed:
+- -----------------
+- Address Size Caller
+- 0x08064c48 0x14 at /home/drepper/tst.c:33
+- 0x08064c60 0x14 at /home/drepper/tst.c:33
+- 0x08064c78 0x14 at /home/drepper/tst.c:33
+- 0x08064c90 0x14 at /home/drepper/tst.c:33
+-
+- Suddenly the output makes much more sense and the user can see
+-immediately where the function calls causing the trouble can be found.
+-
+- Interpreting this output is not complicated. There are at most two
+-different situations being detected. First, `free' was called for
+-pointers which were never returned by one of the allocation functions.
+-This is usually a very bad problem and what this looks like is shown in
+-the first three lines of the output. Situations like this are quite
+-rare and if they appear they show up very drastically: the program
+-normally crashes.
+-
+- The other situation which is much harder to detect are memory leaks.
+-As you can see in the output the `mtrace' function collects all this
+-information and so can say that the program calls an allocation function
+-from line 33 in the source file `/home/drepper/tst-mtrace.c' four times
+-without freeing this memory before the program terminates. Whether
+-this is a real problem remains to be investigated.

+-Obstacks
+---------
+-
+- An "obstack" is a pool of memory containing a stack of objects. You
+-can create any number of separate obstacks, and then allocate objects in
+-specified obstacks. Within each obstack, the last object allocated must
+-always be the first one freed, but distinct obstacks are independent of
+-each other.
+-
+- Aside from this one constraint of order of freeing, obstacks are
+-totally general: an obstack can contain any number of objects of any
+-size. They are implemented with macros, so allocation is usually very
+-fast as long as the objects are usually small. And the only space
+-overhead per object is the padding needed to start each object on a
+-suitable boundary.

+-Creating Obstacks
+-.................
+-
+- The utilities for manipulating obstacks are declared in the header
+-file `obstack.h'.
+-
+- - Data Type: struct obstack
+- An obstack is represented by a data structure of type `struct
+- obstack'. This structure has a small fixed size; it records the
+- status of the obstack and how to find the space in which objects
+- are allocated. It does not contain any of the objects themselves.
+- You should not try to access the contents of the structure
+- directly; use only the functions described in this chapter.
+-
+- You can declare variables of type `struct obstack' and use them as
+-obstacks, or you can allocate obstacks dynamically like any other kind
+-of object. Dynamic allocation of obstacks allows your program to have a
+-variable number of different stacks. (You can even allocate an obstack
+-structure in another obstack, but this is rarely useful.)
+-
+- All the functions that work with obstacks require you to specify
+-which obstack to use. You do this with a pointer of type `struct
+-obstack *'. In the following, we often say "an obstack" when strictly
+-speaking the object at hand is such a pointer.
+-
+- The objects in the obstack are packed into large blocks called
+-"chunks". The `struct obstack' structure points to a chain of the
+-chunks currently in use.
+-
+- The obstack library obtains a new chunk whenever you allocate an
+-object that won't fit in the previous chunk. Since the obstack library
+-manages chunks automatically, you don't need to pay much attention to
+-them, but you do need to supply a function which the obstack library
+-should use to get a chunk. Usually you supply a function which uses
+-`malloc' directly or indirectly. You must also supply a function to
+-free a chunk. These matters are described in the following section.
+-
+-\1f
+-File: libc.info, Node: Preparing for Obstacks, Next: Allocation in an Obstack, Prev: Creating Obstacks, Up: Obstacks
+-
+-Preparing for Using Obstacks
+-............................
+-
+- Each source file in which you plan to use the obstack functions must
+-include the header file `obstack.h', like this:
+-
+- #include <obstack.h>
+-
+- Also, if the source file uses the macro `obstack_init', it must
+-declare or define two functions or macros that will be called by the
+-obstack library. One, `obstack_chunk_alloc', is used to allocate the
+-chunks of memory into which objects are packed. The other,
+-`obstack_chunk_free', is used to return chunks when the objects in them
+-are freed. These macros should appear before any use of obstacks in
+-the source file.
+-
+- Usually these are defined to use `malloc' via the intermediary
+-`xmalloc' (*note Unconstrained Allocation::). This is done with the
+-following pair of macro definitions:
+-
+- #define obstack_chunk_alloc xmalloc
+- #define obstack_chunk_free free
+-
+-Though the memory you get using obstacks really comes from `malloc',
+-using obstacks is faster because `malloc' is called less often, for
+-larger blocks of memory. *Note Obstack Chunks::, for full details.
+-
+- At run time, before the program can use a `struct obstack' object as
+-an obstack, it must initialize the obstack by calling `obstack_init'.
+-
+- - Function: int obstack_init (struct obstack *OBSTACK-PTR)
+- Initialize obstack OBSTACK-PTR for allocation of objects. This
+- function calls the obstack's `obstack_chunk_alloc' function. If
+- allocation of memory fails, the function pointed to by
+- `obstack_alloc_failed_handler' is called. The `obstack_init'
+- function always returns 1 (Compatibility notice: Former versions of
+- obstack returned 0 if allocation failed).
+-
+- Here are two examples of how to allocate the space for an obstack and
+-initialize it. First, an obstack that is a static variable:
+-
+- static struct obstack myobstack;
+- ...
+- obstack_init (&myobstack);
+-
+-Second, an obstack that is itself dynamically allocated:
+-
+- struct obstack *myobstack_ptr
+- = (struct obstack *) xmalloc (sizeof (struct obstack));
+-
+- obstack_init (myobstack_ptr);
+-
+- - Variable: obstack_alloc_failed_handler
+- The value of this variable is a pointer to a function that
+- `obstack' uses when `obstack_chunk_alloc' fails to allocate
+- memory. The default action is to print a message and abort. You
+- should supply a function that either calls `exit' (*note Program
+- Termination::) or `longjmp' (*note Non-Local Exits::) and doesn't
+- return.
+-
+- void my_obstack_alloc_failed (void)
+- ...
+- obstack_alloc_failed_handler = &my_obstack_alloc_failed;

+-
+-Allocation in an Obstack
+-........................
+-
+- The most direct way to allocate an object in an obstack is with
+-`obstack_alloc', which is invoked almost like `malloc'.
+-
+- - Function: void * obstack_alloc (struct obstack *OBSTACK-PTR, int
+- SIZE)
+- This allocates an uninitialized block of SIZE bytes in an obstack
+- and returns its address. Here OBSTACK-PTR specifies which obstack
+- to allocate the block in; it is the address of the `struct obstack'
+- object which represents the obstack. Each obstack function or
+- macro requires you to specify an OBSTACK-PTR as the first argument.
+-
+- This function calls the obstack's `obstack_chunk_alloc' function if
+- it needs to allocate a new chunk of memory; it calls
+- `obstack_alloc_failed_handler' if allocation of memory by
+- `obstack_chunk_alloc' failed.
+-
+- For example, here is a function that allocates a copy of a string STR
+-in a specific obstack, which is in the variable `string_obstack':
+-
+- struct obstack string_obstack;
+-
+- char *
+- copystring (char *string)
+- {
+- size_t len = strlen (string) + 1;
+- char *s = (char *) obstack_alloc (&string_obstack, len);
+- memcpy (s, string, len);
+- return s;
+- }
+-
+- To allocate a block with specified contents, use the function
+-`obstack_copy', declared like this:
+-
+- - Function: void * obstack_copy (struct obstack *OBSTACK-PTR, void
+- *ADDRESS, int SIZE)
+- This allocates a block and initializes it by copying SIZE bytes of
+- data starting at ADDRESS. It calls `obstack_alloc_failed_handler'
+- if allocation of memory by `obstack_chunk_alloc' failed.
+-
+- - Function: void * obstack_copy0 (struct obstack *OBSTACK-PTR, void
+- *ADDRESS, int SIZE)
+- Like `obstack_copy', but appends an extra byte containing a null
+- character. This extra byte is not counted in the argument SIZE.
+-
+- The `obstack_copy0' function is convenient for copying a sequence of
+-characters into an obstack as a null-terminated string. Here is an
+-example of its use:
+-
+- char *
+- obstack_savestring (char *addr, int size)
+- {
+- return obstack_copy0 (&myobstack, addr, size);
+- }
+-
+-Contrast this with the previous example of `savestring' using `malloc'
+-(*note Basic Allocation::).

+-
+-Freeing Objects in an Obstack
+-.............................
+-
+- To free an object allocated in an obstack, use the function
+-`obstack_free'. Since the obstack is a stack of objects, freeing one
+-object automatically frees all other objects allocated more recently in
+-the same obstack.
+-
+- - Function: void obstack_free (struct obstack *OBSTACK-PTR, void
+- *OBJECT)
+- If OBJECT is a null pointer, everything allocated in the obstack
+- is freed. Otherwise, OBJECT must be the address of an object
+- allocated in the obstack. Then OBJECT is freed, along with
+- everything allocated in OBSTACK since OBJECT.
+-
+- Note that if OBJECT is a null pointer, the result is an
+-uninitialized obstack. To free all memory in an obstack but leave it
+-valid for further allocation, call `obstack_free' with the address of
+-the first object allocated on the obstack:
+-
+- obstack_free (obstack_ptr, first_object_allocated_ptr);
+-
+- Recall that the objects in an obstack are grouped into chunks. When
+-all the objects in a chunk become free, the obstack library
+-automatically frees the chunk (*note Preparing for Obstacks::). Then
+-other obstacks, or non-obstack allocation, can reuse the space of the
+-chunk.
+-
+-\1f
+-File: libc.info, Node: Obstack Functions, Next: Growing Objects, Prev: Freeing Obstack Objects, Up: Obstacks
+-
+-Obstack Functions and Macros
+-............................
+-
+- The interfaces for using obstacks may be defined either as functions
+-or as macros, depending on the compiler. The obstack facility works
+-with all C compilers, including both ISO C and traditional C, but there
+-are precautions you must take if you plan to use compilers other than
+-GNU C.
+-
+- If you are using an old-fashioned non-ISO C compiler, all the obstack
+-"functions" are actually defined only as macros. You can call these
+-macros like functions, but you cannot use them in any other way (for
+-example, you cannot take their address).
+-
+- Calling the macros requires a special precaution: namely, the first
+-operand (the obstack pointer) may not contain any side effects, because
+-it may be computed more than once. For example, if you write this:
+-
+- obstack_alloc (get_obstack (), 4);
+-
+-you will find that `get_obstack' may be called several times. If you
+-use `*obstack_list_ptr++' as the obstack pointer argument, you will get
+-very strange results since the incrementation may occur several times.
+-
+- In ISO C, each function has both a macro definition and a function
+-definition. The function definition is used if you take the address of
+-the function without calling it. An ordinary call uses the macro
+-definition by default, but you can request the function definition
+-instead by writing the function name in parentheses, as shown here:
+-
+- char *x;
+- void *(*funcp) ();
+- /* Use the macro. */
+- x = (char *) obstack_alloc (obptr, size);
+- /* Call the function. */
+- x = (char *) (obstack_alloc) (obptr, size);
+- /* Take the address of the function. */
+- funcp = obstack_alloc;
+-
+-This is the same situation that exists in ISO C for the standard library
+-functions. *Note Macro Definitions::.
+-
+- *Warning:* When you do use the macros, you must observe the
+-precaution of avoiding side effects in the first operand, even in ISO C.
+-
+- If you use the GNU C compiler, this precaution is not necessary,
+-because various language extensions in GNU C permit defining the macros
+-so as to compute each argument only once.

+-
+-Signals Arriving While a Handler Runs
+--------------------------------------
+-
+- What happens if another signal arrives while your signal handler
+-function is running?
+-
+- When the handler for a particular signal is invoked, that signal is
+-automatically blocked until the handler returns. That means that if two
+-signals of the same kind arrive close together, the second one will be
+-held until the first has been handled. (The handler can explicitly
+-unblock the signal using `sigprocmask', if you want to allow more
+-signals of this type to arrive; see *Note Process Signal Mask::.)
+-
+- However, your handler can still be interrupted by delivery of another
+-kind of signal. To avoid this, you can use the `sa_mask' member of the
+-action structure passed to `sigaction' to explicitly specify which
+-signals should be blocked while the signal handler runs. These signals
+-are in addition to the signal for which the handler was invoked, and
+-any other signals that are normally blocked by the process. *Note
+-Blocking for Handler::.
+-
+- When the handler returns, the set of blocked signals is restored to
+-the value it had before the handler ran. So using `sigprocmask' inside
+-the handler only affects what signals can arrive during the execution of
+-the handler itself, not what signals can arrive once the handler
+-returns.
+-
+- *Portability Note:* Always use `sigaction' to establish a handler
+-for a signal that you expect to receive asynchronously, if you want
+-your program to work properly on System V Unix. On this system, the
+-handling of a signal whose handler was established with `signal'
+-automatically sets the signal's action back to `SIG_DFL', and the
+-handler must re-establish itself each time it runs. This practice,
+-while inconvenient, does work when signals cannot arrive in succession.
+-However, if another signal can arrive right away, it may arrive before
+-the handler can re-establish itself. Then the second signal would
+-receive the default handling, which could terminate the process.

+-
+-Signals Close Together Merge into One
+--------------------------------------
+-
+- If multiple signals of the same type are delivered to your process
+-before your signal handler has a chance to be invoked at all, the
+-handler may only be invoked once, as if only a single signal had
+-arrived. In effect, the signals merge into one. This situation can
+-arise when the signal is blocked, or in a multiprocessing environment
+-where the system is busy running some other processes while the signals
+-are delivered. This means, for example, that you cannot reliably use a
+-signal handler to count signals. The only distinction you can reliably
+-make is whether at least one signal has arrived since a given time in
+-the past.
+-
+- Here is an example of a handler for `SIGCHLD' that compensates for
+-the fact that the number of signals received may not equal the number of
+-child processes that generate them. It assumes that the program keeps
+-track of all the child processes with a chain of structures as follows:
+-
+- struct process
+- {
+- struct process *next;
+- /* The process ID of this child. */
+- int pid;
+- /* The descriptor of the pipe or pseudo terminal
+- on which output comes from this child. */
+- int input_descriptor;
+- /* Nonzero if this process has stopped or terminated. */
+- sig_atomic_t have_status;
+- /* The status of this child; 0 if running,
+- otherwise a status value from `waitpid'. */
+- int status;
+- };
+-
+- struct process *process_list;
+-
+- This example also uses a flag to indicate whether signals have
+-arrived since some time in the past--whenever the program last cleared
+-it to zero.
+-
+- /* Nonzero means some child's status has changed
+- so look at `process_list' for the details. */
+- int process_status_change;
+-
+- Here is the handler itself:
+-
+- void
+- sigchld_handler (int signo)
+- {
+- int old_errno = errno;
+-
+- while (1) {
+- register int pid;
+- int w;
+- struct process *p;
+-
+- /* Keep asking for a status until we get a definitive result. */
+- do
+- {
+- errno = 0;
+- pid = waitpid (WAIT_ANY, &w, WNOHANG | WUNTRACED);
+- }
+- while (pid <= 0 && errno == EINTR);
+-
+- if (pid <= 0) {
+- /* A real failure means there are no more
+- stopped or terminated child processes, so return. */
+- errno = old_errno;
+- return;
+- }
+-
+- /* Find the process that signaled us, and record its status. */
+-
+- for (p = process_list; p; p = p->next)
+- if (p->pid == pid) {
+- p->status = w;
+- /* Indicate that the `status' field
+- has data to look at. We do this only after storing it. */
+- p->have_status = 1;
+-
+- /* If process has terminated, stop waiting for its output. */
+- if (WIFSIGNALED (w) || WIFEXITED (w))
+- if (p->input_descriptor)
+- FD_CLR (p->input_descriptor, &input_wait_mask);
+-
+- /* The program should check this flag from time to time
+- to see if there is any news in `process_list'. */
+- ++process_status_change;
+- }
+-
+- /* Loop around to handle all the processes
+- that have something to tell us. */
+- }
+- }
+-
+- Here is the proper way to check the flag `process_status_change':
+-
+- if (process_status_change) {
+- struct process *p;
+- process_status_change = 0;
+- for (p = process_list; p; p = p->next)
+- if (p->have_status) {
+- ... Examine `p->status' ...
+- }
+- }
+-
+-It is vital to clear the flag before examining the list; otherwise, if a
+-signal were delivered just before the clearing of the flag, and after
+-the appropriate element of the process list had been checked, the status
+-change would go unnoticed until the next signal arrived to set the flag
+-again. You could, of course, avoid this problem by blocking the signal
+-while scanning the list, but it is much more elegant to guarantee
+-correctness by doing things in the right order.
+-
+- The loop which checks process status avoids examining `p->status'
+-until it sees that status has been validly stored. This is to make sure
+-that the status cannot change in the middle of accessing it. Once
+-`p->have_status' is set, it means that the child process is stopped or
+-terminated, and in either case, it cannot stop or terminate again until
+-the program has taken notice. *Note Atomic Usage::, for more
+-information about coping with interruptions during accesses of a
+-variable.
+-
+- Here is another way you can test whether the handler has run since
+-the last time you checked. This technique uses a counter which is never
+-changed outside the handler. Instead of clearing the count, the program
+-remembers the previous value and sees whether it has changed since the
+-previous check. The advantage of this method is that different parts of
+-the program can check independently, each part checking whether there
+-has been a signal since that part last checked.
+-

+-
+- sig_atomic_t last_process_status_change;

+-Signal Handling and Nonreentrant Functions
+-------------------------------------------
+-
+- Handler functions usually don't do very much. The best practice is
+-to write a handler that does nothing but set an external variable that
+-the program checks regularly, and leave all serious work to the program.
+-This is best because the handler can be called asynchronously, at
+-unpredictable times--perhaps in the middle of a primitive function, or
+-even between the beginning and the end of a C operator that requires
+-multiple instructions. The data structures being manipulated might
+-therefore be in an inconsistent state when the handler function is
+-invoked. Even copying one `int' variable into another can take two
+-instructions on most machines.
+-
+- This means you have to be very careful about what you do in a signal
+-handler.
+-
+- * If your handler needs to access any global variables from your
+- program, declare those variables `volatile'. This tells the
+- compiler that the value of the variable might change
+- asynchronously, and inhibits certain optimizations that would be
+- invalidated by such modifications.
+-
+- * If you call a function in the handler, make sure it is "reentrant"
+- with respect to signals, or else make sure that the signal cannot
+- interrupt a call to a related function.
+-
+- A function can be non-reentrant if it uses memory that is not on the
+-stack.
+-
+- * If a function uses a static variable or a global variable, or a
+- dynamically-allocated object that it finds for itself, then it is
+- non-reentrant and any two calls to the function can interfere.
+-
+- For example, suppose that the signal handler uses `gethostbyname'.
+- This function returns its value in a static object, reusing the
+- same object each time. If the signal happens to arrive during a
+- call to `gethostbyname', or even after one (while the program is
+- still using the value), it will clobber the value that the program
+- asked for.
+-
+- However, if the program does not use `gethostbyname' or any other
+- function that returns information in the same object, or if it
+- always blocks signals around each use, then you are safe.
+-
+- There are a large number of library functions that return values
+- in a fixed object, always reusing the same object in this fashion,
+- and all of them cause the same problem. Function descriptions in
+- this manual always mention this behavior.
+-
+- * If a function uses and modifies an object that you supply, then it
+- is potentially non-reentrant; two calls can interfere if they use
+- the same object.
+-
+- This case arises when you do I/O using streams. Suppose that the
+- signal handler prints a message with `fprintf'. Suppose that the
+- program was in the middle of an `fprintf' call using the same
+- stream when the signal was delivered. Both the signal handler's
+- message and the program's data could be corrupted, because both
+- calls operate on the same data structure--the stream itself.
+-
+- However, if you know that the stream that the handler uses cannot
+- possibly be used by the program at a time when signals can arrive,
+- then you are safe. It is no problem if the program uses some
+- other stream.
+-
+- * On most systems, `malloc' and `free' are not reentrant, because
+- they use a static data structure which records what memory blocks
+- are free. As a result, no library functions that allocate or free
+- memory are reentrant. This includes functions that allocate space
+- to store a result.
+-
+- The best way to avoid the need to allocate memory in a handler is
+- to allocate in advance space for signal handlers to use.
+-
+- The best way to avoid freeing memory in a handler is to flag or
+- record the objects to be freed, and have the program check from
+- time to time whether anything is waiting to be freed. But this
+- must be done with care, because placing an object on a chain is
+- not atomic, and if it is interrupted by another signal handler
+- that does the same thing, you could "lose" one of the objects.
+-
+- * Any function that modifies `errno' is non-reentrant, but you can
+- correct for this: in the handler, save the original value of
+- `errno' and restore it before returning normally. This prevents
+- errors that occur within the signal handler from being confused
+- with errors from system calls at the point the program is
+- interrupted to run the handler.
+-
+- This technique is generally applicable; if you want to call in a
+- handler a function that modifies a particular object in memory,
+- you can make this safe by saving and restoring that object.
+-
+- * Merely reading from a memory object is safe provided that you can
+- deal with any of the values that might appear in the object at a
+- time when the signal can be delivered. Keep in mind that
+- assignment to some data types requires more than one instruction,
+- which means that the handler could run "in the middle of" an
+- assignment to the variable if its type is not atomic. *Note
+- Atomic Data Access::.
+-
+- * Merely writing into a memory object is safe as long as a sudden
+- change in the value, at any time when the handler might run, will
+- not disturb anything.

+-
+-Atomic Data Access and Signal Handling
+---------------------------------------
+-
+- Whether the data in your application concerns atoms, or mere text,
+-you have to be careful about the fact that access to a single datum is
+-not necessarily "atomic". This means that it can take more than one
+-instruction to read or write a single object. In such cases, a signal
+-handler might be invoked in the middle of reading or writing the object.
+-
+- There are three ways you can cope with this problem. You can use
+-data types that are always accessed atomically; you can carefully
+-arrange that nothing untoward happens if an access is interrupted, or
+-you can block all signals around any access that had better not be
+-interrupted (*note Blocking Signals::).

+-Problems with Non-Atomic Access
+-...............................
+-
+- Here is an example which shows what can happen if a signal handler
+-runs in the middle of modifying a variable. (Interrupting the reading
+-of a variable can also lead to paradoxical results, but here we only
+-show writing.)
+-
+- #include <signal.h>
+- #include <stdio.h>
+-
+- struct two_words { int a, b; } memory;
+-
+- void
+- handler(int signum)
+- {
+- printf ("%d,%d\n", memory.a, memory.b);
+- alarm (1);
+- }
+-
+- int
+- main (void)
+- {
+- static struct two_words zeros = { 0, 0 }, ones = { 1, 1 };
+- signal (SIGALRM, handler);
+- memory = zeros;
+- alarm (1);
+- while (1)
+- {
+- memory = zeros;
+- memory = ones;
+- }
+- }
+-
+- This program fills `memory' with zeros, ones, zeros, ones,
+-alternating forever; meanwhile, once per second, the alarm signal
+-handler prints the current contents. (Calling `printf' in the handler
+-is safe in this program because it is certainly not being called outside
+-the handler when the signal happens.)
+-
+- Clearly, this program can print a pair of zeros or a pair of ones.
+-But that's not all it can do! On most machines, it takes several
+-instructions to store a new value in `memory', and the value is stored
+-one word at a time. If the signal is delivered in between these
+-instructions, the handler might find that `memory.a' is zero and
+-`memory.b' is one (or vice versa).
+-
+- On some machines it may be possible to store a new value in `memory'
+-with just one instruction that cannot be interrupted. On these
+-machines, the handler will always print two zeros or two ones.
+-

+-
+-Atomic Types
+-............
+-
+- To avoid uncertainty about interrupting access to a variable, you can
+-use a particular data type for which access is always atomic:
+-`sig_atomic_t'. Reading and writing this data type is guaranteed to
+-happen in a single instruction, so there's no way for a handler to run
+-"in the middle" of an access.
+-
+- The type `sig_atomic_t' is always an integer data type, but which
+-one it is, and how many bits it contains, may vary from machine to
+-machine.
+-
+- - Data Type: sig_atomic_t
+- This is an integer data type. Objects of this type are always
+- accessed atomically.
+-
+- In practice, you can assume that `int' and other integer types no
+-longer than `int' are atomic. You can also assume that pointer types
+-are atomic; that is very convenient. Both of these assumptions are
+-true on all of the machines that the GNU C library supports and on all
+-POSIX systems we know of.
+-
+-\1f
+-File: libc.info, Node: Atomic Usage, Prev: Atomic Types, Up: Atomic Data Access
+-
+-Atomic Usage Patterns
+-.....................
+-
+- Certain patterns of access avoid any problem even if an access is
+-interrupted. For example, a flag which is set by the handler, and
+-tested and cleared by the main program from time to time, is always safe
+-even if access actually requires two instructions. To show that this is
+-so, we must consider each access that could be interrupted, and show
+-that there is no problem if it is interrupted.
+-
+- An interrupt in the middle of testing the flag is safe because
+-either it's recognized to be nonzero, in which case the precise value
+-doesn't matter, or it will be seen to be nonzero the next time it's
+-tested.
+-
+- An interrupt in the middle of clearing the flag is no problem because
+-either the value ends up zero, which is what happens if a signal comes
+-in just before the flag is cleared, or the value ends up nonzero, and
+-subsequent events occur as if the signal had come in just after the flag
+-was cleared. As long as the code handles both of these cases properly,
+-it can also handle a signal in the middle of clearing the flag. (This
+-is an example of the sort of reasoning you need to do to figure out
+-whether non-atomic usage is safe.)
+-
+- Sometimes you can insure uninterrupted access to one object by
+-protecting its use with another object, perhaps one whose type
+-guarantees atomicity. *Note Merged Signals::, for an example.

+-Primitives Interrupted by Signals
+-=================================
+-
+- A signal can arrive and be handled while an I/O primitive such as
+-`open' or `read' is waiting for an I/O device. If the signal handler
+-returns, the system faces the question: what should happen next?
+-
+- POSIX specifies one approach: make the primitive fail right away.
+-The error code for this kind of failure is `EINTR'. This is flexible,
+-but usually inconvenient. Typically, POSIX applications that use signal
+-handlers must check for `EINTR' after each library function that can
+-return it, in order to try the call again. Often programmers forget to
+-check, which is a common source of error.
+-
+- The GNU library provides a convenient way to retry a call after a
+-temporary failure, with the macro `TEMP_FAILURE_RETRY':
+-
+- - Macro: TEMP_FAILURE_RETRY (EXPRESSION)
+- This macro evaluates EXPRESSION once. If it fails and reports
+- error code `EINTR', `TEMP_FAILURE_RETRY' evaluates it again, and
+- over and over until the result is not a temporary failure.
+-
+- The value returned by `TEMP_FAILURE_RETRY' is whatever value
+- EXPRESSION produced.
+-
+- BSD avoids `EINTR' entirely and provides a more convenient approach:
+-to restart the interrupted primitive, instead of making it fail. If
+-you choose this approach, you need not be concerned with `EINTR'.
+-
+- You can choose either approach with the GNU library. If you use
+-`sigaction' to establish a signal handler, you can specify how that
+-handler should behave. If you specify the `SA_RESTART' flag, return
+-from that handler will resume a primitive; otherwise, return from that
+-handler will cause `EINTR'. *Note Flags for Sigaction::.
+-
+- Another way to specify the choice is with the `siginterrupt'
+-function. *Note BSD Handler::.
+-
+- When you don't specify with `sigaction' or `siginterrupt' what a
+-particular handler should do, it uses a default choice. The default
+-choice in the GNU library depends on the feature test macros you have
+-defined. If you define `_BSD_SOURCE' or `_GNU_SOURCE' before calling
+-`signal', the default is to resume primitives; otherwise, the default
+-is to make them fail with `EINTR'. (The library contains alternate
+-versions of the `signal' function, and the feature test macros
+-determine which one you really call.) *Note Feature Test Macros::.
+-
+- The description of each primitive affected by this issue lists
+-`EINTR' among the error codes it can return.
+-
+- There is one situation where resumption never happens no matter which
+-choice you make: when a data-transfer function such as `read' or
+-`write' is interrupted by a signal after transferring part of the data.
+-In this case, the function returns the number of bytes already
+-transferred, indicating partial success.
+-
+- This might at first appear to cause unreliable behavior on
+-record-oriented devices (including datagram sockets; *note Datagrams::),
+-where splitting one `read' or `write' into two would read or write two
+-records. Actually, there is no problem, because interruption after a
+-partial transfer cannot happen on such devices; they always transfer an
+-entire record in one burst, with no waiting once data transfer has
+-started.

+-Generating Signals
+-==================
+-
+- Besides signals that are generated as a result of a hardware trap or
+-interrupt, your program can explicitly send signals to itself or to
+-another process.

+-
+-Signaling Yourself
+-------------------
+-
+- A process can send itself a signal with the `raise' function. This
+-function is declared in `signal.h'.
+-
+- - Function: int raise (int SIGNUM)
+- The `raise' function sends the signal SIGNUM to the calling
+- process. It returns zero if successful and a nonzero value if it
+- fails. About the only reason for failure would be if the value of
+- SIGNUM is invalid.
+-
+- - Function: int gsignal (int SIGNUM)
+- The `gsignal' function does the same thing as `raise'; it is
+- provided only for compatibility with SVID.
+-
+- One convenient use for `raise' is to reproduce the default behavior
+-of a signal that you have trapped. For instance, suppose a user of your
+-program types the SUSP character (usually `C-z'; *note Special
+-Characters::) to send it an interactive stop signal (`SIGTSTP'), and
+-you want to clean up some internal data buffers before stopping. You
+-might set this up like this:
+-
+- #include <signal.h>
+-
+- /* When a stop signal arrives, set the action back to the default
+- and then resend the signal after doing cleanup actions. */
+-
+- void
+- tstp_handler (int sig)
+- {
+- signal (SIGTSTP, SIG_DFL);
+- /* Do cleanup actions here. */
+- ...
+- raise (SIGTSTP);
+- }
+-
+- /* When the process is continued again, restore the signal handler. */

+-Signaling Another Process
+--------------------------
+-
+- The `kill' function can be used to send a signal to another process.
+-In spite of its name, it can be used for a lot of things other than
+-causing a process to terminate. Some examples of situations where you
+-might want to send signals between processes are:
+-
+- * A parent process starts a child to perform a task--perhaps having
+- the child running an infinite loop--and then terminates the child
+- when the task is no longer needed.
+-
+- * A process executes as part of a group, and needs to terminate or
+- notify the other processes in the group when an error or other
+- event occurs.
+-
+- * Two processes need to synchronize while working together.
+-
+- This section assumes that you know a little bit about how processes
+-work. For more information on this subject, see *Note Processes::.
+-
+- The `kill' function is declared in `signal.h'.
+-
+- - Function: int kill (pid_t PID, int SIGNUM)
+- The `kill' function sends the signal SIGNUM to the process or
+- process group specified by PID. Besides the signals listed in
+- *Note Standard Signals::, SIGNUM can also have a value of zero to
+- check the validity of the PID.
+-
+- The PID specifies the process or process group to receive the
+- signal:
+-
+- `PID > 0'
+- The process whose identifier is PID.
+-
+- `PID == 0'
+- All processes in the same process group as the sender.
+-
+- `PID < -1'
+- The process group whose identifier is -PID.
+-
+- `PID == -1'
+- If the process is privileged, send the signal to all
+- processes except for some special system processes.
+- Otherwise, send the signal to all processes with the same
+- effective user ID.
+-
+- A process can send a signal to itself with a call like
+- `kill (getpid(), SIGNUM)'. If `kill' is used by a process to send
+- a signal to itself, and the signal is not blocked, then `kill'
+- delivers at least one signal (which might be some other pending
+- unblocked signal instead of the signal SIGNUM) to that process
+- before it returns.
+-
+- The return value from `kill' is zero if the signal can be sent
+- successfully. Otherwise, no signal is sent, and a value of `-1' is
+- returned. If PID specifies sending a signal to several processes,
+- `kill' succeeds if it can send the signal to at least one of them.
+- There's no way you can tell which of the processes got the signal
+- or whether all of them did.
+-
+- The following `errno' error conditions are defined for this
+- function:
+-
+- `EINVAL'
+- The SIGNUM argument is an invalid or unsupported number.
+-
+- `EPERM'
+- You do not have the privilege to send a signal to the process
+- or any of the processes in the process group named by PID.
+-
+- `ESCRH'
+- The PID argument does not refer to an existing process or
+- group.
+-
+- - Function: int killpg (int PGID, int SIGNUM)
+- This is similar to `kill', but sends signal SIGNUM to the process
+- group PGID. This function is provided for compatibility with BSD;
+- using `kill' to do this is more portable.
+-
+- As a simple example of `kill', the call `kill (getpid (), SIG)' has
+-the same effect as `raise (SIG)'.

+-File: libc.info, Node: Permission for kill, Next: Kill Example, Prev: Signaling Another Process, Up: Generating Signals
+-
+-Permission for using `kill'
+----------------------------
+-
+- There are restrictions that prevent you from using `kill' to send
+-signals to any random process. These are intended to prevent antisocial
+-behavior such as arbitrarily killing off processes belonging to another
+-user. In typical use, `kill' is used to pass signals between parent,
+-child, and sibling processes, and in these situations you normally do
+-have permission to send signals. The only common exception is when you
+-run a setuid program in a child process; if the program changes its
+-real UID as well as its effective UID, you may not have permission to
+-send a signal. The `su' program does this.
+-
+- Whether a process has permission to send a signal to another process
+-is determined by the user IDs of the two processes. This concept is
+-discussed in detail in *Note Process Persona::.
+-
+- Generally, for a process to be able to send a signal to another
+-process, either the sending process must belong to a privileged user
+-(like `root'), or the real or effective user ID of the sending process
+-must match the real or effective user ID of the receiving process. If
+-the receiving process has changed its effective user ID from the
+-set-user-ID mode bit on its process image file, then the owner of the
+-process image file is used in place of its current effective user ID.
+-In some implementations, a parent process might be able to send signals
+-to a child process even if the user ID's don't match, and other
+-implementations might enforce other restrictions.
+-
+- The `SIGCONT' signal is a special case. It can be sent if the
+-sender is part of the same session as the receiver, regardless of user
+-IDs.
+-
+-\1f
+-File: libc.info, Node: Kill Example, Prev: Permission for kill, Up: Generating Signals
+-
+-Using `kill' for Communication
+-------------------------------
+-
+- Here is a longer example showing how signals can be used for
+-interprocess communication. This is what the `SIGUSR1' and `SIGUSR2'
+-signals are provided for. Since these signals are fatal by default,
+-the process that is supposed to receive them must trap them through
+-`signal' or `sigaction'.
+-
+- In this example, a parent process forks a child process and then
+-waits for the child to complete its initialization. The child process
+-tells the parent when it is ready by sending it a `SIGUSR1' signal,
+-using the `kill' function.
+-
+- #include <signal.h>
+- #include <stdio.h>
+- #include <sys/types.h>
+- #include <unistd.h>
+-
+- /* When a `SIGUSR1' signal arrives, set this variable. */
+- volatile sig_atomic_t usr_interrupt = 0;
+-
+- void
+- synch_signal (int sig)
+- {
+- usr_interrupt = 1;
+- }
+-
+- /* The child process executes this function. */
+- void
+- child_function (void)
+- {
+- /* Perform initialization. */
+- printf ("I'm here!!! My pid is %d.\n", (int) getpid ());
+-
+- /* Let parent know you're done. */
+- kill (getppid (), SIGUSR1);
+-
+- /* Continue with execution. */
+- puts ("Bye, now....");
+- exit (0);
+- }
+-
+- int
+- main (void)
+- {
+- struct sigaction usr_action;
+- sigset_t block_mask;
+- pid_t child_id;
+-
+- /* Establish the signal handler. */
+- sigfillset (&block_mask);
+- usr_action.sa_handler = synch_signal;
+- usr_action.sa_mask = block_mask;
+- usr_action.sa_flags = 0;
+- sigaction (SIGUSR1, &usr_action, NULL);
+-
+- /* Create the child process. */
+- child_id = fork ();
+- if (child_id == 0)
+- child_function (); /* Does not return. */
+-
+- /* Busy wait for the child to send a signal. */
+- while (!usr_interrupt)
+- ;
+-
+- /* Now continue execution. */
+- puts ("That's all, folks!");
+-
+- return 0;
+- }
+-
+- This example uses a busy wait, which is bad, because it wastes CPU
+-cycles that other programs could otherwise use. It is better to ask the

+-Blocking Signals
+-================
+-
+- Blocking a signal means telling the operating system to hold it and
+-deliver it later. Generally, a program does not block signals
+-indefinitely--it might as well ignore them by setting their actions to
+-`SIG_IGN'. But it is useful to block signals briefly, to prevent them
+-from interrupting sensitive operations. For instance:
+-
+- * You can use the `sigprocmask' function to block signals while you
+- modify global variables that are also modified by the handlers for
+- these signals.
+-
+- * You can set `sa_mask' in your `sigaction' call to block certain
+- signals while a particular signal handler runs. This way, the
+- signal handler can run without being interrupted itself by signals.

+-
+-Why Blocking Signals is Useful
+-------------------------------
+-
+- Temporary blocking of signals with `sigprocmask' gives you a way to
+-prevent interrupts during critical parts of your code. If signals
+-arrive in that part of the program, they are delivered later, after you
+-unblock them.
+-
+- One example where this is useful is for sharing data between a signal
+-handler and the rest of the program. If the type of the data is not
+-`sig_atomic_t' (*note Atomic Data Access::), then the signal handler
+-could run when the rest of the program has only half finished reading
+-or writing the data. This would lead to confusing consequences.
+-
+- To make the program reliable, you can prevent the signal handler from
+-running while the rest of the program is examining or modifying that
+-data--by blocking the appropriate signal around the parts of the
+-program that touch the data.
+-
+- Blocking signals is also necessary when you want to perform a certain
+-action only if a signal has not arrived. Suppose that the handler for
+-the signal sets a flag of type `sig_atomic_t'; you would like to test
+-the flag and perform the action if the flag is not set. This is
+-unreliable. Suppose the signal is delivered immediately after you test
+-the flag, but before the consequent action: then the program will
+-perform the action even though the signal has arrived.
+-
+- The only way to test reliably for whether a signal has yet arrived
+-is to test while the signal is blocked.
+-
+-\1f
+-File: libc.info, Node: Signal Sets, Next: Process Signal Mask, Prev: Why Block, Up: Blocking Signals
+-
+-Signal Sets
+------------
+-
+- All of the signal blocking functions use a data structure called a
+-"signal set" to specify what signals are affected. Thus, every
+-activity involves two stages: creating the signal set, and then passing
+-it as an argument to a library function.
+-
+- These facilities are declared in the header file `signal.h'.
+-
+- - Data Type: sigset_t
+- The `sigset_t' data type is used to represent a signal set.
+- Internally, it may be implemented as either an integer or structure
+- type.
+-
+- For portability, use only the functions described in this section
+- to initialize, change, and retrieve information from `sigset_t'
+- objects--don't try to manipulate them directly.
+-
+- There are two ways to initialize a signal set. You can initially
+-specify it to be empty with `sigemptyset' and then add specified
+-signals individually. Or you can specify it to be full with
+-`sigfillset' and then delete specified signals individually.
+-
+- You must always initialize the signal set with one of these two
+-functions before using it in any other way. Don't try to set all the
+-signals explicitly because the `sigset_t' object might include some
+-other information (like a version field) that needs to be initialized as
+-well. (In addition, it's not wise to put into your program an
+-assumption that the system has no signals aside from the ones you know
+-about.)
+-
+- - Function: int sigemptyset (sigset_t *SET)
+- This function initializes the signal set SET to exclude all of the
+- defined signals. It always returns `0'.
+-
+- - Function: int sigfillset (sigset_t *SET)
+- This function initializes the signal set SET to include all of the
+- defined signals. Again, the return value is `0'.
+-
+- - Function: int sigaddset (sigset_t *SET, int SIGNUM)
+- This function adds the signal SIGNUM to the signal set SET. All
+- `sigaddset' does is modify SET; it does not block or unblock any

+-
+-Process Signal Mask
+--------------------
+-
+- The collection of signals that are currently blocked is called the
+-"signal mask". Each process has its own signal mask. When you create
+-a new process (*note Creating a Process::), it inherits its parent's
+-mask. You can block or unblock signals with total flexibility by
+-modifying the signal mask.
+-
+- The prototype for the `sigprocmask' function is in `signal.h'.
+-
+- Note that you must not use `sigprocmask' in multi-threaded processes,
+-because each thread has its own signal mask and there is no single
+-process signal mask. According to POSIX, the behavior of `sigprocmask'
+-in a multi-threaded process is "unspeficied". Instead, use
+-`pthread_sigmask'. *Note Threads and Signal Handling::.
+-
+- - Function: int sigprocmask (int HOW, const sigset_t *restrict SET,
+- sigset_t *restrict OLDSET)
+- The `sigprocmask' function is used to examine or change the calling
+- process's signal mask. The HOW argument determines how the signal
+- mask is changed, and must be one of the following values:
+-
+- `SIG_BLOCK'
+- Block the signals in `set'--add them to the existing mask. In
+- other words, the new mask is the union of the existing mask
+- and SET.
+-
+- `SIG_UNBLOCK'
+- Unblock the signals in SET--remove them from the existing
+- mask.
+-
+- `SIG_SETMASK'
+- Use SET for the mask; ignore the previous value of the mask.
+-
+- The last argument, OLDSET, is used to return information about the
+- old process signal mask. If you just want to change the mask
+- without looking at it, pass a null pointer as the OLDSET argument.
+- Similarly, if you want to know what's in the mask without changing
+- it, pass a null pointer for SET (in this case the HOW argument is
+- not significant). The OLDSET argument is often used to remember
+- the previous signal mask in order to restore it later. (Since the
+- signal mask is inherited over `fork' and `exec' calls, you can't
+- predict what its contents are when your program starts running.)
+-
+- If invoking `sigprocmask' causes any pending signals to be
+- unblocked, at least one of those signals is delivered to the
+- process before `sigprocmask' returns. The order in which pending
+- signals are delivered is not specified, but you can control the
+- order explicitly by making multiple `sigprocmask' calls to unblock
+- various signals one at a time.
+-
+- The `sigprocmask' function returns `0' if successful, and `-1' to
+- indicate an error. The following `errno' error conditions are
+- defined for this function:
+-
+- `EINVAL'
+- The HOW argument is invalid.
+-
+- You can't block the `SIGKILL' and `SIGSTOP' signals, but if the
+- signal set includes these, `sigprocmask' just ignores them instead
+- of returning an error status.
+-
+- Remember, too, that blocking program error signals such as `SIGFPE'
+- leads to undesirable results for signals generated by an actual
+- program error (as opposed to signals sent with `raise' or `kill').
+- This is because your program may be too broken to be able to
+- continue executing to a point where the signal is unblocked again.

+-Blocking to Test for Delivery of a Signal
+------------------------------------------
+-
+- Now for a simple example. Suppose you establish a handler for
+-`SIGALRM' signals that sets a flag whenever a signal arrives, and your
+-main program checks this flag from time to time and then resets it.
+-You can prevent additional `SIGALRM' signals from arriving in the
+-meantime by wrapping the critical part of the code with calls to
+-`sigprocmask', like this:
+-
+- /* This variable is set by the SIGALRM signal handler. */
+- volatile sig_atomic_t flag = 0;
+-
+- int
+- main (void)
+- {
+- sigset_t block_alarm;
+-
+- ...
+-
+- /* Initialize the signal mask. */
+- sigemptyset (&block_alarm);
+- sigaddset (&block_alarm, SIGALRM);
+-
+- while (1)
+- {
+- /* Check if a signal has arrived; if so, reset the flag. */
+- sigprocmask (SIG_BLOCK, &block_alarm, NULL);
+- if (flag)
+- {

+- }
+- }

+-File: libc.info, Node: Blocking for Handler, Next: Checking for Pending Signals, Prev: Testing for Delivery, Up: Blocking Signals
+-
+-Blocking Signals for a Handler
+-------------------------------
+-
+- When a signal handler is invoked, you usually want it to be able to
+-finish without being interrupted by another signal. From the moment the
+-handler starts until the moment it finishes, you must block signals that
+-might confuse it or corrupt its data.
+-
+- When a handler function is invoked on a signal, that signal is
+-automatically blocked (in addition to any other signals that are already
+-in the process's signal mask) during the time the handler is running.
+-If you set up a handler for `SIGTSTP', for instance, then the arrival
+-of that signal forces further `SIGTSTP' signals to wait during the
+-execution of the handler.
+-
+- However, by default, other kinds of signals are not blocked; they can
+-arrive during handler execution.
+-
+- The reliable way to block other kinds of signals during the
+-execution of the handler is to use the `sa_mask' member of the
+-`sigaction' structure.
+-
+- Here is an example:
+-
+- #include <signal.h>
+- #include <stddef.h>
+-
+- void catch_stop ();
+-
+- void
+- install_handler (void)
+- {
+- struct sigaction setup_action;
+- sigset_t block_mask;
+-
+- sigemptyset (&block_mask);
+- /* Block other terminal-generated signals while handler runs. */
+- sigaddset (&block_mask, SIGINT);
+- sigaddset (&block_mask, SIGQUIT);
+- setup_action.sa_handler = catch_stop;
+- setup_action.sa_mask = block_mask;
+- setup_action.sa_flags = 0;
+- sigaction (SIGTSTP, &setup_action, NULL);
+- }
+-
+- This is more reliable than blocking the other signals explicitly in
+-the code for the handler. If you block signals explicitly in the
+-handler, you can't avoid at least a short interval at the beginning of
+-the handler where they are not yet blocked.
+-
+- You cannot remove signals from the process's current mask using this
+-mechanism. However, you can make calls to `sigprocmask' within your
+-handler to block or unblock signals as you wish.
+-
+- In any case, when the handler returns, the system restores the mask
+-that was in place before the handler was entered. If any signals that
+-become unblocked by this restoration are pending, the process will
+-receive those signals immediately, before returning to the code that was
+-interrupted.
+-

+-File: libc.info, Node: Checking for Pending Signals, Next: Remembering a Signal, Prev: Blocking for Handler, Up: Blocking Signals
+-
+-Checking for Pending Signals
+-----------------------------
+-
+- You can find out which signals are pending at any time by calling
+-`sigpending'. This function is declared in `signal.h'.
+-
+- - Function: int sigpending (sigset_t *SET)
+- The `sigpending' function stores information about pending signals
+- in SET. If there is a pending signal that is blocked from
+- delivery, then that signal is a member of the returned set. (You
+- can test whether a particular signal is a member of this set using
+- `sigismember'; see *Note Signal Sets::.)
+-
+- The return value is `0' if successful, and `-1' on failure.
+-
+- Testing whether a signal is pending is not often useful. Testing
+-when that signal is not blocked is almost certainly bad design.
+-
+- Here is an example.
+-
+- #include <signal.h>
+- #include <stddef.h>
+-
+- sigset_t base_mask, waiting_mask;
+-
+- sigemptyset (&base_mask);
+- sigaddset (&base_mask, SIGINT);
+- sigaddset (&base_mask, SIGTSTP);
+-
+- /* Block user interrupts while doing other processing. */
+- sigprocmask (SIG_SETMASK, &base_mask, NULL);
+- ...
+-
+- /* After a while, check to see whether any signals are pending. */
+- sigpending (&waiting_mask);
+- if (sigismember (&waiting_mask, SIGINT)) {
+- /* User has tried to kill the process. */
+- }
+- else if (sigismember (&waiting_mask, SIGTSTP)) {
+- /* User has tried to stop the process. */
+- }
+-
+- Remember that if there is a particular signal pending for your
+-process, additional signals of that same type that arrive in the
+-meantime might be discarded. For example, if a `SIGINT' signal is
+-pending when another `SIGINT' signal arrives, your program will
+-probably only see one of them when you unblock this signal.
+-
+- *Portability Note:* The `sigpending' function is new in POSIX.1.
+-Older systems have no equivalent facility.

+-
+-Remembering a Signal to Act On Later
+-------------------------------------
+-
+- Instead of blocking a signal using the library facilities, you can
+-get almost the same results by making the handler set a flag to be
+-tested later, when you "unblock". Here is an example:
+-
+- /* If this flag is nonzero, don't handle the signal right away. */
+- volatile sig_atomic_t signal_pending;
+-
+- /* This is nonzero if a signal arrived and was not handled. */
+- volatile sig_atomic_t defer_signal;
+-
+- void
+- handler (int signum)
+- {
+- if (defer_signal)
+- signal_pending = signum;
+- else
+- ... /* "Really" handle the signal. */
+- }
+-
+- ...
+-
+- void
+- update_mumble (int frob)
+- {
+- /* Prevent signals from having immediate effect. */
+- defer_signal++;
+- /* Now update `mumble', without worrying about interruption. */
+- mumble.a = 1;
+- mumble.b = hack ();
+- mumble.c = frob;
+- /* We have updated `mumble'. Handle any signal that came in. */
+- defer_signal--;
+- if (defer_signal == 0 && signal_pending != 0)
+- raise (signal_pending);
+- }
+-
+- Note how the particular signal that arrives is stored in
+-`signal_pending'. That way, we can handle several types of
+-inconvenient signals with the same mechanism.
+-
+- We increment and decrement `defer_signal' so that nested critical
+-sections will work properly; thus, if `update_mumble' were called with
+-`signal_pending' already nonzero, signals would be deferred not only
+-within `update_mumble', but also within the caller. This is also why
+-we do not check `signal_pending' if `defer_signal' is still nonzero.
+-
+- The incrementing and decrementing of `defer_signal' each require more
+-than one instruction; it is possible for a signal to happen in the
+-middle. But that does not cause any problem. If the signal happens
+-early enough to see the value from before the increment or decrement,
+-that is equivalent to a signal which came before the beginning of the
+-increment or decrement, which is a case that works properly.
+-
+- It is absolutely vital to decrement `defer_signal' before testing
+-`signal_pending', because this avoids a subtle bug. If we did these
+-things in the other order, like this,
+-
+- if (defer_signal == 1 && signal_pending != 0)
+- raise (signal_pending);
+- defer_signal--;
+-
+-then a signal arriving in between the `if' statement and the decrement
+-would be effectively "lost" for an indefinite amount of time. The
+-handler would merely set `defer_signal', but the program having already
+-tested this variable, it would not test the variable again.
+-
+- Bugs like these are called "timing errors". They are especially bad
+-because they happen only rarely and are nearly impossible to reproduce.
+-You can't expect to find them with a debugger as you would find a
+-reproducible bug. So it is worth being especially careful to avoid
+-them.
+-
+- (You would not be tempted to write the code in this order, given the
+-use of `defer_signal' as a counter which must be tested along with
+-`signal_pending'. After all, testing for zero is cleaner than testing
+-for one. But if you did not use `defer_signal' as a counter, and gave
+-it values of zero and one only, then either order might seem equally
+-simple. This is a further advantage of using a counter for
+-`defer_signal': it will reduce the chance you will write the code in
+-the wrong order and create a subtle bug.)

+-File: libc.info, Node: Using Pause, Next: Pause Problems, Up: Waiting for a Signal
+-
+-Using `pause'
+--------------
+-
+- The simple way to wait until a signal arrives is to call `pause'.
+-Please read about its disadvantages, in the following section, before
+-you use it.
+-
+- - Function: int pause ()
+- The `pause' function suspends program execution until a signal
+- arrives whose action is either to execute a handler function, or to
+- terminate the process.
+-
+- If the signal causes a handler function to be executed, then
+- `pause' returns. This is considered an unsuccessful return (since
+- "successful" behavior would be to suspend the program forever), so
+- the return value is `-1'. Even if you specify that other
+- primitives should resume when a system handler returns (*note
+- Interrupted Primitives::), this has no effect on `pause'; it
+- always fails when a signal is handled.
+-
+- The following `errno' error conditions are defined for this
+- function:
+-
+- `EINTR'
+- The function was interrupted by delivery of a signal.
+-
+- If the signal causes program termination, `pause' doesn't return
+- (obviously).
+-
+- This function is a cancellation point in multithreaded programs.
+- This is a problem if the thread allocates some resources (like
+- memory, file descriptors, semaphores or whatever) at the time
+- `pause' is called. If the thread gets cancelled these resources
+- stay allocated until the program ends. To avoid this calls to
+- `pause' should be protected using cancellation handlers.
+-
+- The `pause' function is declared in `unistd.h'.
+-
+-\1f
+-File: libc.info, Node: Pause Problems, Next: Sigsuspend, Prev: Using Pause, Up: Waiting for a Signal
+-
+-Problems with `pause'
+----------------------
+-
+- The simplicity of `pause' can conceal serious timing errors that can
+-make a program hang mysteriously.
+-
+- It is safe to use `pause' if the real work of your program is done
+-by the signal handlers themselves, and the "main program" does nothing
+-but call `pause'. Each time a signal is delivered, the handler will do
+-the next batch of work that is to be done, and then return, so that the
+-main loop of the program can call `pause' again.
+-
+- You can't safely use `pause' to wait until one more signal arrives,
+-and then resume real work. Even if you arrange for the signal handler
+-to cooperate by setting a flag, you still can't use `pause' reliably.
+-Here is an example of this problem:
+-
+- /* `usr_interrupt' is set by the signal handler. */
+- if (!usr_interrupt)
+- pause ();
+-
+- /* Do work once the signal arrives. */
+- ...
+-
+-This has a bug: the signal could arrive after the variable
+-`usr_interrupt' is checked, but before the call to `pause'. If no
+-further signals arrive, the process would never wake up again.
+-
+- You can put an upper limit on the excess waiting by using `sleep' in
+-a loop, instead of using `pause'. (*Note Sleeping::, for more about
+-`sleep'.) Here is what this looks like:
+-
+- /* `usr_interrupt' is set by the signal handler.
+- while (!usr_interrupt)
+- sleep (1);
+-
+- /* Do work once the signal arrives. */
+- ...
+-
+- For some purposes, that is good enough. But with a little more
+-complexity, you can wait reliably until a particular signal handler is
+-run, using `sigsuspend'. *Note Sigsuspend::.
+-
+-\1f
+-File: libc.info, Node: Sigsuspend, Prev: Pause Problems, Up: Waiting for a Signal
+-
+-Using `sigsuspend'
+-------------------
+-
+- The clean and reliable way to wait for a signal to arrive is to
+-block it and then use `sigsuspend'. By using `sigsuspend' in a loop,
+-you can wait for certain kinds of signals, while letting other kinds of
+-signals be handled by their handlers.
+-
+- - Function: int sigsuspend (const sigset_t *SET)
+- This function replaces the process's signal mask with SET and then
+- suspends the process until a signal is delivered whose action is
+- either to terminate the process or invoke a signal handling
+- function. In other words, the program is effectively suspended
+- until one of the signals that is not a member of SET arrives.
+-
+- If the process is woken up by delivery of a signal that invokes a
+- handler function, and the handler function returns, then
+- `sigsuspend' also returns.
+-
+- The mask remains SET only as long as `sigsuspend' is waiting. The
+- function `sigsuspend' always restores the previous signal mask
+- when it returns.
+-
+- The return value and error conditions are the same as for `pause'.
+-
+- With `sigsuspend', you can replace the `pause' or `sleep' loop in
+-the previous section with something completely reliable:
+-
+- sigset_t mask, oldmask;
+-
+- ...
+-
+- /* Set up the mask of signals to temporarily block. */
+- sigemptyset (&mask);
+- sigaddset (&mask, SIGUSR1);
+-
+- ...
+-
+- /* Wait for a signal to arrive. */
+- sigprocmask (SIG_BLOCK, &mask, &oldmask);
+- while (!usr_interrupt)
+- sigsuspend (&oldmask);
+- sigprocmask (SIG_UNBLOCK, &mask, NULL);
+-
+- This last piece of code is a little tricky. The key point to
+-remember here is that when `sigsuspend' returns, it resets the process's
+-signal mask to the original value, the value from before the call to
+-`sigsuspend'--in this case, the `SIGUSR1' signal is once again blocked.
+-The second call to `sigprocmask' is necessary to explicitly unblock
+-this signal.
+-
+- One other point: you may be wondering why the `while' loop is
+-necessary at all, since the program is apparently only waiting for one
+-`SIGUSR1' signal. The answer is that the mask passed to `sigsuspend'
+-permits the process to be woken up by the delivery of other kinds of
+-signals, as well--for example, job control signals. If the process is
+-woken up by a signal that doesn't set `usr_interrupt', it just suspends
+-itself again until the "right" kind of signal eventually arrives.
+-
+- This technique takes a few more lines of preparation, but that is
+-needed just once for each kind of wait criterion you want to use. The
+-code that actually waits is just four lines.

+-
+-Using a Separate Signal Stack
+-=============================
+-
+- A signal stack is a special area of memory to be used as the
+-execution stack during signal handlers. It should be fairly large, to
+-avoid any danger that it will overflow in turn; the macro `SIGSTKSZ' is
+-defined to a canonical size for signal stacks. You can use `malloc' to
+-allocate the space for the stack. Then call `sigaltstack' or
+-`sigstack' to tell the system to use that space for the signal stack.
+-
+- You don't need to write signal handlers differently in order to use a
+-signal stack. Switching from one stack to the other happens
+-automatically. (Some non-GNU debuggers on some machines may get
+-confused if you examine a stack trace while a handler that uses the
+-signal stack is running.)
+-
+- There are two interfaces for telling the system to use a separate
+-signal stack. `sigstack' is the older interface, which comes from 4.2
+-BSD. `sigaltstack' is the newer interface, and comes from 4.4 BSD.
+-The `sigaltstack' interface has the advantage that it does not require
+-your program to know which direction the stack grows, which depends on
+-the specific machine and operating system.
+-
+- - Data Type: stack_t
+- This structure describes a signal stack. It contains the
+- following members:
+-
+- `void *ss_sp'
+- This points to the base of the signal stack.
+-
+- `size_t ss_size'
+- This is the size (in bytes) of the signal stack which `ss_sp'
+- points to. You should set this to however much space you
+- allocated for the stack.
+-
+- There are two macros defined in `signal.h' that you should
+- use in calculating this size:
+-
+- `SIGSTKSZ'
+- This is the canonical size for a signal stack. It is
+- judged to be sufficient for normal uses.
+-
+- `MINSIGSTKSZ'
+- This is the amount of signal stack space the operating
+- system needs just to implement signal delivery. The
+- size of a signal stack *must* be greater than this.
+-
+- For most cases, just using `SIGSTKSZ' for `ss_size' is
+- sufficient. But if you know how much stack space your
+- program's signal handlers will need, you may want to use
+- a different size. In this case, you should allocate
+- `MINSIGSTKSZ' additional bytes for the signal stack and
+- increase `ss_size' accordingly.
+-
+- `int ss_flags'
+- This field contains the bitwise OR of these flags:
+-
+- `SS_DISABLE'
+- This tells the system that it should not use the signal
+- stack.
+-
+- `SS_ONSTACK'
+- This is set by the system, and indicates that the signal
+- stack is currently in use. If this bit is not set, then
+- signals will be delivered on the normal user stack.
+-
+- - Function: int sigaltstack (const stack_t *restrict STACK, stack_t
+- *restrict OLDSTACK)
+- The `sigaltstack' function specifies an alternate stack for use
+- during signal handling. When a signal is received by the process
+- and its action indicates that the signal stack is used, the system
+- arranges a switch to the currently installed signal stack while
+- the handler for that signal is executed.
+-
+- If OLDSTACK is not a null pointer, information about the currently
+- installed signal stack is returned in the location it points to.
+- If STACK is not a null pointer, then this is installed as the new
+- stack for use by signal handlers.
+-
+- The return value is `0' on success and `-1' on failure. If
+- `sigaltstack' fails, it sets `errno' to one of these values:
+-
+- `EINVAL'
+- You tried to disable a stack that was in fact currently in
+- use.
+-
+- `ENOMEM'
+- The size of the alternate stack was too small. It must be
+- greater than `MINSIGSTKSZ'.
+-
+- Here is the older `sigstack' interface. You should use
+-`sigaltstack' instead on systems that have it.
+-
+- - Data Type: struct sigstack
+- This structure describes a signal stack. It contains the
+- following members:
+-
+- `void *ss_sp'
+- This is the stack pointer. If the stack grows downwards on
+- your machine, this should point to the top of the area you
+- allocated. If the stack grows upwards, it should point to
+- the bottom.
+-
+- `int ss_onstack'
+- This field is true if the process is currently using this
+- stack.
+-
+- - Function: int sigstack (const struct sigstack *STACK, struct
+- sigstack *OLDSTACK)
+- The `sigstack' function specifies an alternate stack for use during
+- signal handling. When a signal is received by the process and its
+- action indicates that the signal stack is used, the system
+- arranges a switch to the currently installed signal stack while
+- the handler for that signal is executed.
+-
+- If OLDSTACK is not a null pointer, information about the currently
+- installed signal stack is returned in the location it points to.
+- If STACK is not a null pointer, then this is installed as the new
+- stack for use by signal handlers.
+-
+- The return value is `0' on success and `-1' on failure.

+-BSD Signal Handling
+-===================
+-
+- This section describes alternative signal handling functions derived
+-from BSD Unix. These facilities were an advance, in their time; today,
+-they are mostly obsolete, and supported mainly for compatibility with
+-BSD Unix.
+-
+- There are many similarities between the BSD and POSIX signal handling
+-facilities, because the POSIX facilities were inspired by the BSD
+-facilities. Besides having different names for all the functions to
+-avoid conflicts, the main differences between the two are:
+-
+- * BSD Unix represents signal masks as an `int' bit mask, rather than
+- as a `sigset_t' object.
+-
+- * The BSD facilities use a different default for whether an
+- interrupted primitive should fail or resume. The POSIX facilities
+- make system calls fail unless you specify that they should resume.
+- With the BSD facility, the default is to make system calls resume
+- unless you say they should fail. *Note Interrupted Primitives::.
+-
+- The BSD facilities are declared in `signal.h'.

+-
+-BSD Function to Establish a Handler
+------------------------------------
+-
+- - Data Type: struct sigvec
+- This data type is the BSD equivalent of `struct sigaction' (*note
+- Advanced Signal Handling::); it is used to specify signal actions
+- to the `sigvec' function. It contains the following members:
+-
+- `sighandler_t sv_handler'
+- This is the handler function.
+-
+- `int sv_mask'
+- This is the mask of additional signals to be blocked while
+- the handler function is being called.
+-
+- `int sv_flags'
+- This is a bit mask used to specify various flags which affect
+- the behavior of the signal. You can also refer to this field
+- as `sv_onstack'.
+-
+- These symbolic constants can be used to provide values for the
+-`sv_flags' field of a `sigvec' structure. This field is a bit mask
+-value, so you bitwise-OR the flags of interest to you together.
+-
+- - Macro: int SV_ONSTACK
+- If this bit is set in the `sv_flags' field of a `sigvec'
+- structure, it means to use the signal stack when delivering the
+- signal.
+-
+- - Macro: int SV_INTERRUPT
+- If this bit is set in the `sv_flags' field of a `sigvec'
+- structure, it means that system calls interrupted by this kind of
+- signal should not be restarted if the handler returns; instead,
+- the system calls should return with a `EINTR' error status. *Note
+- Interrupted Primitives::.
+-
+- - Macro: int SV_RESETHAND
+- If this bit is set in the `sv_flags' field of a `sigvec'
+- structure, it means to reset the action for the signal back to
+- `SIG_DFL' when the signal is received.
+-
+- - Function: int sigvec (int SIGNUM, const struct sigvec *ACTION,struct
+- sigvec *OLD-ACTION)
+- This function is the equivalent of `sigaction' (*note Advanced
+- Signal Handling::); it installs the action ACTION for the signal
+- SIGNUM, returning information about the previous action in effect
+- for that signal in OLD-ACTION.
+-
+- - Function: int siginterrupt (int SIGNUM, int FAILFLAG)
+- This function specifies which approach to use when certain
+- primitives are interrupted by handling signal SIGNUM. If FAILFLAG
+- is false, signal SIGNUM restarts primitives. If FAILFLAG is true,
+- handling SIGNUM causes these primitives to fail with error code
+- `EINTR'. *Note Interrupted Primitives::.

+-BSD Functions for Blocking Signals
+-----------------------------------
+-
+- - Macro: int sigmask (int SIGNUM)
+- This macro returns a signal mask that has the bit for signal SIGNUM
+- set. You can bitwise-OR the results of several calls to `sigmask'
+- together to specify more than one signal. For example,
+-
+- (sigmask (SIGTSTP) | sigmask (SIGSTOP)
+- | sigmask (SIGTTIN) | sigmask (SIGTTOU))
+-
+- specifies a mask that includes all the job-control stop signals.
+-
+- - Function: int sigblock (int MASK)
+- This function is equivalent to `sigprocmask' (*note Process Signal
+- Mask::) with a HOW argument of `SIG_BLOCK': it adds the signals
+- specified by MASK to the calling process's set of blocked signals.
+- The return value is the previous set of blocked signals.
+-
+- - Function: int sigsetmask (int MASK)
+- This function equivalent to `sigprocmask' (*note Process Signal
+- Mask::) with a HOW argument of `SIG_SETMASK': it sets the calling
+- process's signal mask to MASK. The return value is the previous
+- set of blocked signals.
+-
+- - Function: int sigpause (int MASK)
+- This function is the equivalent of `sigsuspend' (*note Waiting for
+- a Signal::): it sets the calling process's signal mask to MASK,
+- and waits for a signal to arrive. On return the previous set of
+- blocked signals is restored.

+-The Basic Program/System Interface
+-**********************************
+-
+- "Processes" are the primitive units for allocation of system
+-resources. Each process has its own address space and (usually) one
+-thread of control. A process executes a program; you can have multiple
+-processes executing the same program, but each process has its own copy
+-of the program within its own address space and executes it
+-independently of the other copies. Though it may have multiple threads
+-of control within the same program and a program may be composed of
+-multiple logically separate modules, a process always executes exactly
+-one program.
+-
+- Note that we are using a specific definition of "program" for the
+-purposes of this manual, which corresponds to a common definition in the
+-context of Unix system. In popular usage, "program" enjoys a much
+-broader definition; it can refer for example to a system's kernel, an
+-editor macro, a complex package of software, or a discrete section of
+-code executing within a process.
+-
+- Writing the program is what this manual is all about. This chapter
+-explains the most basic interface between your program and the system
+-that runs, or calls, it. This includes passing of parameters (arguments
+-and environment) from the system, requesting basic services from the
+-system, and telling the system the program is done.
+-
+- A program starts another program with the `exec' family of system
+-calls. This chapter looks at program startup from the execee's point
+-of view. To see the event from the execor's point of view, *Note
+-Executing a File::.

+-Program Arguments
+-=================
+-
+- The system starts a C program by calling the function `main'. It is
+-up to you to write a function named `main'--otherwise, you won't even
+-be able to link your program without errors.
+-
+- In ISO C you can define `main' either to take no arguments, or to
+-take two arguments that represent the command line arguments to the
+-program, like this:
+-
+- int main (int ARGC, char *ARGV[])
+-
+- The command line arguments are the whitespace-separated tokens given
+-in the shell command used to invoke the program; thus, in `cat foo
+-bar', the arguments are `foo' and `bar'. The only way a program can
+-look at its command line arguments is via the arguments of `main'. If
+-`main' doesn't take arguments, then you cannot get at the command line.
+-
+- The value of the ARGC argument is the number of command line
+-arguments. The ARGV argument is a vector of C strings; its elements
+-are the individual command line argument strings. The file name of the
+-program being run is also included in the vector as the first element;
+-the value of ARGC counts this element. A null pointer always follows
+-the last element: `ARGV[ARGC]' is this null pointer.
+-
+- For the command `cat foo bar', ARGC is 3 and ARGV has three
+-elements, `"cat"', `"foo"' and `"bar"'.
+-
+- In Unix systems you can define `main' a third way, using three
+-arguments:
+-
+- int main (int ARGC, char *ARGV[], char *ENVP[])
+-
+- The first two arguments are just the same. The third argument ENVP
+-gives the program's environment; it is the same as the value of
+-`environ'. *Note Environment Variables::. POSIX.1 does not allow this
+-three-argument form, so to be portable it is best to write `main' to
+-take two arguments, and use the value of `environ'.

+-
+-Program Argument Syntax Conventions
+------------------------------------
+-
+- POSIX recommends these conventions for command line arguments.
+-`getopt' (*note Getopt::) and `argp_parse' (*note Argp::) make it easy
+-to implement them.
+-
+- * Arguments are options if they begin with a hyphen delimiter (`-').
+-
+- * Multiple options may follow a hyphen delimiter in a single token if
+- the options do not take arguments. Thus, `-abc' is equivalent to
+- `-a -b -c'.
+-
+- * Option names are single alphanumeric characters (as for `isalnum';
+- *note Classification of Characters::).
+-
+- * Certain options require an argument. For example, the `-o' command
+- of the `ld' command requires an argument--an output file name.
+-
+- * An option and its argument may or may not appear as separate
+- tokens. (In other words, the whitespace separating them is
+- optional.) Thus, `-o foo' and `-ofoo' are equivalent.
+-
+- * Options typically precede other non-option arguments.
+-
+- The implementations of `getopt' and `argp_parse' in the GNU C
+- library normally make it appear as if all the option arguments were
+- specified before all the non-option arguments for the purposes of
+- parsing, even if the user of your program intermixed option and
+- non-option arguments. They do this by reordering the elements of
+- the ARGV array. This behavior is nonstandard; if you want to
+- suppress it, define the `_POSIX_OPTION_ORDER' environment variable.
+- *Note Standard Environment::.
+-
+- * The argument `--' terminates all options; any following arguments
+- are treated as non-option arguments, even if they begin with a
+- hyphen.
+-
+- * A token consisting of a single hyphen character is interpreted as
+- an ordinary non-option argument. By convention, it is used to
+- specify input from or output to the standard input and output
+- streams.
+-
+- * Options may be supplied in any order, or appear multiple times.
+- The interpretation is left up to the particular application
+- program.
+-
+- GNU adds "long options" to these conventions. Long options consist
+-of `--' followed by a name made of alphanumeric characters and dashes.
+-Option names are typically one to three words long, with hyphens to
+-separate words. Users can abbreviate the option names as long as the
+-abbreviations are unique.
+-
+- To specify an argument for a long option, write `--NAME=VALUE'.
+-This syntax enables a long option to accept an argument that is itself
+-optional.
+-
+- Eventually, the GNU system will provide completion for long option
+-names in the shell.

+-Parsing Program Arguments
+--------------------------
+-
+- If the syntax for the command line arguments to your program is
+-simple enough, you can simply pick the arguments off from ARGV by hand.
+-But unless your program takes a fixed number of arguments, or all of the
+-arguments are interpreted in the same way (as file names, for example),
+-you are usually better off using `getopt' (*note Getopt::) or
+-`argp_parse' (*note Argp::) to do the parsing.
+-
+- `getopt' is more standard (the short-option only version of it is a
+-part of the POSIX standard), but using `argp_parse' is often easier,
+-both for very simple and very complex option structures, because it
+-does more of the dirty work for you.

+-
+-Using the `getopt' function
+----------------------------
+-
+- Here are the details about how to call the `getopt' function. To
+-use this facility, your program must include the header file `unistd.h'.
+-
+- - Variable: int opterr
+- If the value of this variable is nonzero, then `getopt' prints an
+- error message to the standard error stream if it encounters an
+- unknown option character or an option with a missing required
+- argument. This is the default behavior. If you set this variable
+- to zero, `getopt' does not print any messages, but it still
+- returns the character `?' to indicate an error.
+-
+- - Variable: int optopt
+- When `getopt' encounters an unknown option character or an option
+- with a missing required argument, it stores that option character
+- in this variable. You can use this for providing your own
+- diagnostic messages.
+-
+- - Variable: int optind
+- This variable is set by `getopt' to the index of the next element
+- of the ARGV array to be processed. Once `getopt' has found all of
+- the option arguments, you can use this variable to determine where
+- the remaining non-option arguments begin. The initial value of
+- this variable is `1'.
+-
+- - Variable: char * optarg
+- This variable is set by `getopt' to point at the value of the
+- option argument, for those options that accept arguments.
+-
+- - Function: int getopt (int ARGC, char **ARGV, const char *OPTIONS)
+- The `getopt' function gets the next option argument from the
+- argument list specified by the ARGV and ARGC arguments. Normally
+- these values come directly from the arguments received by `main'.
+-
+- The OPTIONS argument is a string that specifies the option
+- characters that are valid for this program. An option character
+- in this string can be followed by a colon (`:') to indicate that
+- it takes a required argument. If an option character is followed
+- by two colons (`::'), its argument is optional; this is a GNU
+- extension.
+-
+- `getopt' has three ways to deal with options that follow
+- non-options ARGV elements. The special argument `--' forces in
+- all cases the end of option scanning.
+-
+- * The default is to permute the contents of ARGV while scanning
+- it so that eventually all the non-options are at the end.
+- This allows options to be given in any order, even with
+- programs that were not written to expect this.
+-
+- * If the OPTIONS argument string begins with a hyphen (`-'),
+- this is treated specially. It permits arguments that are not
+- options to be returned as if they were associated with option
+- character `\1'.
+-
+- * POSIX demands the following behavior: The first non-option
+- stops option processing. This mode is selected by either
+- setting the environment variable `POSIXLY_CORRECT' or
+- beginning the OPTIONS argument string with a plus sign (`+').
+-
+- The `getopt' function returns the option character for the next
+- command line option. When no more option arguments are available,
+- it returns `-1'. There may still be more non-option arguments; you
+- must compare the external variable `optind' against the ARGC
+- parameter to check this.
+-
+- If the option has an argument, `getopt' returns the argument by
+- storing it in the variable OPTARG. You don't ordinarily need to
+- copy the `optarg' string, since it is a pointer into the original
+- ARGV array, not into a static area that might be overwritten.
+-
+- If `getopt' finds an option character in ARGV that was not
+- included in OPTIONS, or a missing option argument, it returns `?'
+- and sets the external variable `optopt' to the actual option
+- character. If the first character of OPTIONS is a colon (`:'),
+- then `getopt' returns `:' instead of `?' to indicate a missing
+- option argument. In addition, if the external variable `opterr'
+- is nonzero (which is the default), `getopt' prints an error
+- message.

+-Example of Parsing Arguments with `getopt'
+-------------------------------------------
+-
+- Here is an example showing how `getopt' is typically used. The key
+-points to notice are:
+-
+- * Normally, `getopt' is called in a loop. When `getopt' returns
+- `-1', indicating no more options are present, the loop terminates.
+-
+- * A `switch' statement is used to dispatch on the return value from
+- `getopt'. In typical use, each case just sets a variable that is
+- used later in the program.
+-
+- * A second loop is used to process the remaining non-option
+- arguments.

+-Parsing Long Options with `getopt_long'
+----------------------------------------
+-
+- To accept GNU-style long options as well as single-character options,
+-use `getopt_long' instead of `getopt'. This function is declared in
+-`getopt.h', not `unistd.h'. You should make every program accept long
+-options if it uses any options, for this takes little extra work and
+-helps beginners remember how to use the program.
+-
+- - Data Type: struct option
+- This structure describes a single long option name for the sake of
+- `getopt_long'. The argument LONGOPTS must be an array of these
+- structures, one for each long option. Terminate the array with an
+- element containing all zeros.
+-
+- The `struct option' structure has these fields:
+-
+- `const char *name'
+- This field is the name of the option. It is a string.
+-
+- `int has_arg'
+- This field says whether the option takes an argument. It is
+- an integer, and there are three legitimate values:
+- `no_argument', `required_argument' and `optional_argument'.
+-
+- `int *flag'
+- `int val'
+- These fields control how to report or act on the option when
+- it occurs.
+-
+- If `flag' is a null pointer, then the `val' is a value which
+- identifies this option. Often these values are chosen to
+- uniquely identify particular long options.
+-
+- If `flag' is not a null pointer, it should be the address of
+- an `int' variable which is the flag for this option. The
+- value in `val' is the value to store in the flag to indicate
+- that the option was seen.
+-
+- - Function: int getopt_long (int ARGC, char *const *ARGV, const char
+- *SHORTOPTS, const struct option *LONGOPTS, int *INDEXPTR)
+- Decode options from the vector ARGV (whose length is ARGC). The
+- argument SHORTOPTS describes the short options to accept, just as
+- it does in `getopt'. The argument LONGOPTS describes the long
+- options to accept (see above).
+-
+- When `getopt_long' encounters a short option, it does the same
+- thing that `getopt' would do: it returns the character code for the
+- option, and stores the options argument (if it has one) in
+- `optarg'.
+-
+- When `getopt_long' encounters a long option, it takes actions based
+- on the `flag' and `val' fields of the definition of that option.
+-
+- If `flag' is a null pointer, then `getopt_long' returns the
+- contents of `val' to indicate which option it found. You should
+- arrange distinct values in the `val' field for options with
+- different meanings, so you can decode these values after
+- `getopt_long' returns. If the long option is equivalent to a short
+- option, you can use the short option's character code in `val'.
+-
+- If `flag' is not a null pointer, that means this option should just
+- set a flag in the program. The flag is a variable of type `int'
+- that you define. Put the address of the flag in the `flag' field.
+- Put in the `val' field the value you would like this option to
+- store in the flag. In this case, `getopt_long' returns `0'.
+-
+- For any long option, `getopt_long' tells you the index in the array
+- LONGOPTS of the options definition, by storing it into
+- `*INDEXPTR'. You can get the name of the option with
+- `LONGOPTS[*INDEXPTR].name'. So you can distinguish among long
+- options either by the values in their `val' fields or by their
+- indices. You can also distinguish in this way among long options
+- that set flags.
+-
+- When a long option has an argument, `getopt_long' puts the argument
+- value in the variable `optarg' before returning. When the option
+- has no argument, the value in `optarg' is a null pointer. This is
+- how you can tell whether an optional argument was supplied.
+-
+- When `getopt_long' has no more options to handle, it returns `-1',
+- and leaves in the variable `optind' the index in ARGV of the next
+- remaining argument.
+-
+- Since long option names were used before before the `getopt_long'
+-options was invented there are program interfaces which require programs
+-to recognize options like `-option value' instead of `--option value'.
+-To enable these programs to use the GNU getopt functionality there is
+-one more function available.
+-
+- - Function: int getopt_long_only (int ARGC, char *const *ARGV, const
+- char *SHORTOPTS, const struct option *LONGOPTS, int *INDEXPTR)
+- The `getopt_long_only' function is equivalent to the `getopt_long'
+- function but it allows to specify the user of the application to
+- pass long options with only `-' instead of `--'. The `--' prefix
+- is still recognized but instead of looking through the short
+- options if a `-' is seen it is first tried whether this parameter
+- names a long option. If not, it is parsed as a short option.
+-
+- Assuming `getopt_long_only' is used starting an application with
+-
+- app -foo
+-
+- the `getopt_long_only' will first look for a long option named
+- `foo'. If this is not found, the short options `f', `o', and
+- again `o' are recognized.

+-Parsing Program Options with Argp
+-=================================
+-
+- "Argp" is an interface for parsing unix-style argument vectors.
+-*Note Program Arguments::.
+-
+- Argp provides features unavailable in the more commonly used
+-`getopt' interface. These features include automatically producing
+-output in response to the `--help' and `--version' options, as
+-described in the GNU coding standards. Using argp makes it less likely
+-that programmers will neglect to implement these additional options or
+-keep them up to date.
+-
+- Argp also provides the ability to merge several independently defined
+-option parsers into one, mediating conflicts between them and making the
+-result appear seamless. A library can export an argp option parser that
+-user programs might employ in conjunction with their own option parsers,
+-resulting in less work for the user programs. Some programs may use
+-only argument parsers exported by libraries, thereby achieving
+-consistent and efficient option-parsing for abstractions implemented by
+-the libraries.
+-
+- The header file `<argp.h>' should be included to use argp.
+-
+-The `argp_parse' Function
+--------------------------
+-
+- The main interface to argp is the `argp_parse' function. In many
+-cases, calling `argp_parse' is the only argument-parsing code needed in
+-`main'. *Note Program Arguments::.
+-
+- - Function: error_t argp_parse (const struct argp *ARGP, int ARGC,
+- char **ARGV, unsigned FLAGS, int *ARG_INDEX, void *INPUT)
+- The `argp_parse' function parses the arguments in ARGV, of length
+- ARGC, using the argp parser ARGP. *Note Argp Parsers::.
+-
+- A value of zero is the same as a `struct argp'containing all
+- zeros. FLAGS is a set of flag bits that modify the parsing
+- behavior. *Note Argp Flags::. INPUT is passed through to the argp
+- parser ARGP, and has meaning defined by ARGP. A typical usage is
+- to pass a pointer to a structure which is used for specifying
+- parameters to the parser and passing back the results.
+-
+- Unless the `ARGP_NO_EXIT' or `ARGP_NO_HELP' flags are included in
+- FLAGS, calling `argp_parse' may result in the program exiting.
+- This behavior is true if an error is detected, or when an unknown
+- option is encountered. *Note Program Termination::.
+-
+- If ARG_INDEX is non-null, the index of the first unparsed option
+- in ARGV is returned as a value.
+-
+- The return value is zero for successful parsing, or an error code
+- (*note Error Codes::) if an error is detected. Different argp
+- parsers may return arbitrary error codes, but the standard error
+- codes are: `ENOMEM' if a memory allocation error occurred, or
+- `EINVAL' if an unknown option or option argument is encountered.

+-Argp Global Variables
+----------------------
+-
+- These variables make it easy for user programs to implement the
+-`--version' option and provide a bug-reporting address in the `--help'
+-output. These are implemented in argp by default.
+-
+- - Variable: const char * argp_program_version
+- If defined or set by the user program to a non-zero value, then a
+- `--version' option is added when parsing with `argp_parse', which
+- will print the `--version' string followed by a newline and exit.
+- The exception to this is if the `ARGP_NO_EXIT' flag is used.
+-
+- - Variable: const char * argp_program_bug_address
+- If defined or set by the user program to a non-zero value,
+- `argp_program_bug_address' should point to a string that will be
+- printed at the end of the standard output for the `--help' option,
+- embedded in a sentence that says `Report bugs to ADDRESS.'.
+-
+- - Variable: argp_program_version_hook
+- If defined or set by the user program to a non-zero value, a
+- `--version' option is added when parsing with `arg_parse', which
+- prints the program version and exits with a status of zero. This
+- is not the case if the `ARGP_NO_HELP' flag is used. If the
+- `ARGP_NO_EXIT' flag is set, the exit behavior of the program is
+- suppressed or modified, as when the argp parser is going to be
+- used by other programs.
+-
+- It should point to a function with this type of signature:
+-
+- void PRINT-VERSION (FILE *STREAM, struct argp_state *STATE)
+-
+- *Note Argp Parsing State::, for an explanation of STATE.
+-
+- This variable takes precedence over `argp_program_version', and is
+- useful if a program has version information not easily expressed
+- in a simple string.
+-
+- - Variable: error_t argp_err_exit_status
+- This is the exit status used when argp exits due to a parsing
+- error. If not defined or set by the user program, this defaults
+- to: `EX_USAGE' from `<sysexits.h>'.

+-Specifying Argp Parsers
+------------------------
+-
+- The first argument to the `argp_parse' function is a pointer to a
+-`struct argp', which is known as an "argp parser":
+-
+- - Data Type: struct argp
+- This structure specifies how to parse a given set of options and
+- arguments, perhaps in conjunction with other argp parsers. It has
+- the following fields:
+-
+- `const struct argp_option *options'
+- A pointer to a vector of `argp_option' structures specifying
+- which options this argp parser understands; it may be zero if
+- there are no options at all. *Note Argp Option Vectors::.
+-
+- `argp_parser_t parser'
+- A pointer to a function that defines actions for this parser;
+- it is called for each option parsed, and at other
+- well-defined points in the parsing process. A value of zero
+- is the same as a pointer to a function that always returns
+- `ARGP_ERR_UNKNOWN'. *Note Argp Parser Functions::.
+-
+- `const char *args_doc'
+- If non-zero, a string describing what non-option arguments
+- are called by this parser. This is only used to print the
+- `Usage:' message. If it contains newlines, the strings
+- separated by them are considered alternative usage patterns
+- and printed on separate lines. Lines after the first are
+- prefixed by ` or: ' instead of `Usage:'.
+-
+- `const char *doc'
+- If non-zero, a string containing extra text to be printed
+- before and after the options in a long help message, with the
+- two sections separated by a vertical tab (`'\v'', `'\013'')
+- character. By convention, the documentation before the
+- options is just a short string explaining what the program
+- does. Documentation printed after the options describe
+- behavior in more detail.
+-
+- `const struct argp_child *children'
+- A pointer to a vector of `argp_children' structures. This
+- pointer specifies which additional argp parsers should be
+- combined with this one. *Note Argp Children::.
+-
+- `char *(*help_filter)(int KEY, const char *TEXT, void *INPUT)'
+- If non-zero, a pointer to a function that filters the output
+- of help messages. *Note Argp Help Filtering::.
+-
+- `const char *argp_domain'
+- If non-zero, the strings used in the argp library are
+- translated using the domain described by this string. If
+- zero, the current default domain is used.
+-
+-
+- Of the above group, `options', `parser', `args_doc', and the `doc'
+-fields are usually all that are needed. If an argp parser is defined
+-as an initialized C variable, only the fields used need be specified in
+-the initializer. The rest will default to zero due to the way C
+-structure initialization works. This design is exploited in most argp
+-structures; the most-used fields are grouped near the beginning, the
+-unused fields left unspecified.

+-
+-Specifying Options in an Argp Parser
+-------------------------------------
+-
+- The `options' field in a `struct argp' points to a vector of `struct
+-argp_option' structures, each of which specifies an option that the
+-argp parser supports. Multiple entries may be used for a single option
+-provided it has multiple names. This should be terminated by an entry
+-with zero in all fields. Note that when using an initialized C array
+-for options, writing `{ 0 }' is enough to achieve this.
+-
+- - Data Type: struct argp_option
+- This structure specifies a single option that an argp parser
+- understands, as well as how to parse and document that option. It
+- has the following fields:
+-
+- `const char *name'
+- The long name for this option, corresponding to the long
+- option `--NAME'; this field may be zero if this option _only_
+- has a short name. To specify multiple names for an option,
+- additional entries may follow this one, with the
+- `OPTION_ALIAS' flag set. *Note Argp Option Flags::.
+-
+- `int key'
+- The integer key provided by the current option to the option
+- parser. If KEY has a value that is a printable ASCII
+- character (i.e., `isascii (KEY)' is true), it _also_
+- specifies a short option `-CHAR', where CHAR is the ASCII
+- character with the code KEY.
+-
+- `const char *arg'
+- If non-zero, this is the name of an argument associated with
+- this option, which must be provided (e.g., with the
+- `--NAME=VALUE' or `-CHAR VALUE' syntaxes), unless the
+- `OPTION_ARG_OPTIONAL' flag (*note Argp Option Flags::) is
+- set, in which case it _may_ be provided.
+-
+- `int flags'
+- Flags associated with this option, some of which are referred
+- to above. *Note Argp Option Flags::.
+-
+- `const char *doc'
+- A documentation string for this option, for printing in help
+- messages.
+-
+- If both the `name' and `key' fields are zero, this string
+- will be printed tabbed left from the normal option column,
+- making it useful as a group header. This will be the first
+- thing printed in its group. In this usage, it's conventional
+- to end the string with a `:' character.
+-
+- `int group'
+- Group identity for this option.
+-
+- In a long help message, options are sorted alphabetically
+- within each group, and the groups presented in the order 0,
+- 1, 2, ..., N, -M, ..., -2, -1.
+-
+- Every entry in an options array with this field 0 will
+- inherit the group number of the previous entry, or zero if
+- it's the first one. If it's a group header with `name' and
+- `key' fields both zero, the previous entry + 1 is the
+- default. Automagic options such as `--help' are put into
+- group -1.
+-
+- Note that because of C structure initialization rules, this
+- field often need not be specified, because 0 is the correct
+- value.

+-Flags for Argp Options
+-......................
+-
+- The following flags may be or'd together in the `flags' field of a
+-`struct argp_option'. These flags control various aspects of how that
+-option is parsed or displayed in help messages:
+-
+-`OPTION_ARG_OPTIONAL'
+- The argument associated with this option is optional.
+-
+-`OPTION_HIDDEN'
+- This option isn't displayed in any help messages.
+-
+-`OPTION_ALIAS'
+- This option is an alias for the closest previous non-alias option.
+- This means that it will be displayed in the same help entry, and
+- will inherit fields other than `name' and `key' from the option
+- being aliased.
+-
+-`OPTION_DOC'
+- This option isn't actually an option and should be ignored by the
+- actual option parser. It is an arbitrary section of documentation
+- that should be displayed in much the same manner as the options.
+- This is known as a "documentation option".
+-
+- If this flag is set, then the option `name' field is displayed
+- unmodified (e.g., no `--' prefix is added) at the left-margin where
+- a _short_ option would normally be displayed, and this
+- documentation string is left in it's usual place. For purposes of
+- sorting, any leading whitespace and punctuation is ignored, unless
+- the first non-whitespace character is `-'. This entry is displayed
+- after all options, after `OPTION_DOC' entries with a leading `-',
+- in the same group.
+-
+-`OPTION_NO_USAGE'
+- This option shouldn't be included in `long' usage messages, but
+- should still be included in other help messages. This is intended
+- for options that are completely documented in an argp's `args_doc'
+- field. *Note Argp Parsers::. Including this option in the
+- generic usage list would be redundant, and should be avoided.
+-
+- For instance, if `args_doc' is `"FOO BAR\n-x BLAH"', and the `-x'
+- option's purpose is to distinguish these two cases, `-x' should
+- probably be marked `OPTION_NO_USAGE'.

+-
+-Argp Parser Functions
+----------------------
+-
+- The function pointed to by the `parser' field in a `struct argp'
+-(*note Argp Parsers::) defines what actions take place in response to
+-each option or argument parsed. It is also used as a hook, allowing a
+-parser to perform tasks at certain other points during parsing.
+-
+- Argp parser functions have the following type signature:
+-
+- error_t PARSER (int KEY, char *ARG, struct argp_state *STATE)
+-
+-where the arguments are as follows:
+-
+-KEY
+- For each option that is parsed, PARSER is called with a value of
+- KEY from that option's `key' field in the option vector. *Note
+- Argp Option Vectors::. PARSER is also called at other times with
+- special reserved keys, such as `ARGP_KEY_ARG' for non-option
+- arguments. *Note Argp Special Keys::.
+-
+-ARG
+- If KEY is an option, ARG is its given value. This defaults to
+- zero if no value is specified. Only options that have a non-zero
+- `arg' field can ever have a value. These must _always_ have a
+- value unless the `OPTION_ARG_OPTIONAL' flag is specified. If the
+- input being parsed specifies a value for an option that doesn't
+- allow one, an error results before PARSER ever gets called.
+-
+- If KEY is `ARGP_KEY_ARG', ARG is a non-option argument. Other
+- special keys always have a zero ARG.
+-
+-STATE
+- STATE points to a `struct argp_state', containing useful
+- information about the current parsing state for use by PARSER.
+- *Note Argp Parsing State::.
+-
+- When PARSER is called, it should perform whatever action is
+-appropriate for KEY, and return `0' for success, `ARGP_ERR_UNKNOWN' if
+-the value of KEY is not handled by this parser function, or a unix
+-error code if a real error occurred. *Note Error Codes::.
+-
+- - Macro: int ARGP_ERR_UNKNOWN
+- Argp parser functions should return `ARGP_ERR_UNKNOWN' for any KEY
+- value they do not recognize, or for non-option arguments (`KEY ==
+- ARGP_KEY_ARG') that they are not equipped to handle.
+-
+- A typical parser function uses a switch statement on KEY:
+-
+- error_t
+- parse_opt (int key, char *arg, struct argp_state *state)
+- {
+- switch (key)
+- {
+- case OPTION_KEY:
+- ACTION
+- break;
+- ...
+- default:
+- return ARGP_ERR_UNKNOWN;
+- }
+- return 0;
+- }

+-
+-Special Keys for Argp Parser Functions
+-......................................
+-
+- In addition to key values corresponding to user options, the KEY
+-argument to argp parser functions may have a number of other special
+-values. In the following example ARG and STATE refer to parser
+-function arguments. *Note Argp Parser Functions::.
+-
+-`ARGP_KEY_ARG'
+- This is not an option at all, but rather a command line argument,
+- whose value is pointed to by ARG.
+-
+- When there are multiple parser functions in play due to argp
+- parsers being combined, it's impossible to know which one will
+- handle a specific argument. Each is called until one returns 0 or
+- an error other than `ARGP_ERR_UNKNOWN'; if an argument is not
+- handled, `argp_parse' immediately returns success, without parsing
+- any more arguments.
+-
+- Once a parser function returns success for this key, that fact is
+- recorded, and the `ARGP_KEY_NO_ARGS' case won't be used.
+- _However_, if while processing the argument a parser function
+- decrements the `next' field of its STATE argument, the option
+- won't be considered processed; this is to allow you to actually
+- modify the argument, perhaps into an option, and have it processed
+- again.
+-
+-`ARGP_KEY_ARGS'
+- If a parser function returns `ARGP_ERR_UNKNOWN' for
+- `ARGP_KEY_ARG', it is immediately called again with the key
+- `ARGP_KEY_ARGS', which has a similar meaning, but is slightly more
+- convenient for consuming all remaining arguments. ARG is 0, and
+- the tail of the argument vector may be found at `STATE->argv +
+- STATE->next'. If success is returned for this key, and
+- `STATE->next' is unchanged, all remaining arguments are considered
+- to have been consumed. Otherwise, the amount by which
+- `STATE->next' has been adjusted indicates how many were used.
+- Here's an example that uses both, for different args:
+-
+- ...
+- case ARGP_KEY_ARG:
+- if (STATE->arg_num == 0)
+- /* First argument */
+- first_arg = ARG;
+- else
+- /* Let the next case parse it. */
+- return ARGP_KEY_UNKNOWN;
+- break;
+- case ARGP_KEY_ARGS:
+- remaining_args = STATE->argv + STATE->next;
+- num_remaining_args = STATE->argc - STATE->next;
+- break;
+-
+-`ARGP_KEY_END'
+- This indicates that there are no more command line arguments.
+- Parser functions are called in a different order, children first.
+- This allows each parser to clean up its state for the parent.
+-
+-`ARGP_KEY_NO_ARGS'
+- Because it's common to do some special processing if there aren't
+- any non-option args, parser functions are called with this key if
+- they didn't successfully process any non-option arguments. This
+- is called just before `ARGP_KEY_END', where more general validity
+- checks on previously parsed arguments take place.
+-
+-`ARGP_KEY_INIT'
+- This is passed in before any parsing is done. Afterwards, the
+- values of each element of the `child_input' field of STATE, if
+- any, are copied to each child's state to be the initial value of
+- the `input' when _their_ parsers are called.
+-
+-`ARGP_KEY_SUCCESS'
+- Passed in when parsing has successfully been completed, even if
+- arguments remain.
+-
+-`ARGP_KEY_ERROR'
+- Passed in if an error has occurred and parsing is terminated. In
+- this case a call with a key of `ARGP_KEY_SUCCESS' is never made.
+-
+-`ARGP_KEY_FINI'
+- The final key ever seen by any parser, even after
+- `ARGP_KEY_SUCCESS' and `ARGP_KEY_ERROR'. Any resources allocated
+- by `ARGP_KEY_INIT' may be freed here. At times, certain resources
+- allocated are to be returned to the caller after a successful
+- parse. In that case, those particular resources can be freed in
+- the `ARGP_KEY_ERROR' case.
+-
+- In all cases, `ARGP_KEY_INIT' is the first key seen by parser
+-functions, and `ARGP_KEY_FINI' the last, unless an error was returned
+-by the parser for `ARGP_KEY_INIT'. Other keys can occur in one the
+-following orders. OPT refers to an arbitrary option key:
+-
+-OPT... `ARGP_KEY_NO_ARGS' `ARGP_KEY_END' `ARGP_KEY_SUCCESS'
+- The arguments being parsed did not contain any non-option
+- arguments.
+-
+-( OPT | `ARGP_KEY_ARG' )... `ARGP_KEY_END' `ARGP_KEY_SUCCESS'
+- All non-option arguments were successfully handled by a parser
+- function. There may be multiple parser functions if multiple argp
+- parsers were combined.
+-
+-( OPT | `ARGP_KEY_ARG' )... `ARGP_KEY_SUCCESS'
+- Some non-option argument went unrecognized.
+-
+- This occurs when every parser function returns `ARGP_KEY_UNKNOWN'
+- for an argument, in which case parsing stops at that argument if
+- ARG_INDEX is a null pointer. Otherwise an error occurs.
+-
+- In all cases, if a non-null value for ARG_INDEX gets passed to
+-`argp_parse', the index of the first unparsed command-line argument is
+-passed back in that value.
+-
+- If an error occurs and is either detected by argp or because a parser
+-function returned an error value, each parser is called with
+-`ARGP_KEY_ERROR'. No further calls are made, except the final call
+-with `ARGP_KEY_FINI'.

+-Functions For Use in Argp Parsers
+-.................................
+-
+- Argp provides a number of functions available to the user of argp
+-(*note Argp Parser Functions::), mostly for producing error messages.
+-These take as their first argument the STATE argument to the parser
+-function. *Note Argp Parsing State::.
+-
+- - Function: void argp_usage (const struct argp_state *STATE)
+- Outputs the standard usage message for the argp parser referred to
+- by STATE to `STATE->err_stream' and terminate the program with
+- `exit (argp_err_exit_status)'. *Note Argp Global Variables::.
+-
+- - Function: void argp_error (const struct argp_state *STATE, const
+- char *FMT, ...)
+- Prints the printf format string FMT and following args, preceded
+- by the program name and `:', and followed by a `Try ... --help'
+- message, and terminates the program with an exit status of
+- `argp_err_exit_status'. *Note Argp Global Variables::.
+-
+- - Function: void argp_failure (const struct argp_state *STATE, int
+- STATUS, int ERRNUM, const char *FMT, ...)
+- Similar to the standard gnu error-reporting function `error', this
+- prints the program name and `:', the printf format string FMT, and
+- the appropriate following args. If it is non-zero, the standard
+- unix error text for ERRNUM is printed. If STATUS is non-zero, it
+- terminates the program with that value as its exit status.
+-
+- The difference between `argp_failure' and `argp_error' is that
+- `argp_error' is for _parsing errors_, whereas `argp_failure' is
+- for other problems that occur during parsing but don't reflect a
+- syntactic problem with the input, such as illegal values for
+- options, bad phase of the moon, etc.
+-
+- - Function: void argp_state_help (const struct argp_state *STATE, FILE
+- *STREAM, unsigned FLAGS)
+- Outputs a help message for the argp parser referred to by STATE,
+- to STREAM. The FLAGS argument determines what sort of help
+- message is produced. *Note Argp Help Flags::.
+-
+- Error output is sent to `STATE->err_stream', and the program name
+-printed is `STATE->name'.
+-
+- The output or program termination behavior of these functions may be
+-suppressed if the `ARGP_NO_EXIT' or `ARGP_NO_ERRS' flags are passed to
+-`argp_parse'. *Note Argp Flags::.
+-
+- This behavior is useful if an argp parser is exported for use by
+-other programs (e.g., by a library), and may be used in a context where
+-it is not desirable to terminate the program in response to parsing
+-errors. In argp parsers intended for such general use, and for the
+-case where the program _doesn't_ terminate, calls to any of these
+-functions should be followed by code that returns the appropriate error
+-code:
+-
+- if (BAD ARGUMENT SYNTAX)
+- {
+- argp_usage (STATE);
+- return EINVAL;
+- }
+-
+-If a parser function will _only_ be used when `ARGP_NO_EXIT' is not
+-set, the return may be omitted.

+-
+-Argp Parsing State
+-..................
+-
+- The third argument to argp parser functions (*note Argp Parser
+-Functions::) is a pointer to a `struct argp_state', which contains
+-information about the state of the option parsing.
+-
+- - Data Type: struct argp_state
+- This structure has the following fields, which may be modified as
+- noted:
+-
+- `const struct argp *const root_argp'
+- The top level argp parser being parsed. Note that this is
+- often _not_ the same `struct argp' passed into `argp_parse' by
+- the invoking program. *Note Argp::. It is an internal argp
+- parser that contains options implemented by `argp_parse'
+- itself, such as `--help'.
+-
+- `int argc'
+- `char **argv'
+- The argument vector being parsed. This may be modified.
+-
+- `int next'
+- The index in `argv' of the next argument to be parsed. This
+- may be modified.
+-
+- One way to consume all remaining arguments in the input is to
+- set `STATE->next = STATE->argc', perhaps after recording the
+- value of the `next' field to find the consumed arguments. The
+- current option can be re-parsed immediately by decrementing
+- this field, then modifying `STATE->argv[STATE->next]' to
+- reflect the option that should be reexamined.
+-
+- `unsigned flags'
+- The flags supplied to `argp_parse'. These may be modified,
+- although some flags may only take effect when `argp_parse' is
+- first invoked. *Note Argp Flags::.
+-
+- `unsigned arg_num'
+- While calling a parsing function with the KEY argument
+- `ARGP_KEY_ARG', this represents the number of the current arg,
+- starting at 0. It is incremented after each `ARGP_KEY_ARG'
+- call returns. At all other times, this is the number of
+- `ARGP_KEY_ARG' arguments that have been processed.
+-
+- `int quoted'
+- If non-zero, the index in `argv' of the first argument
+- following a special `--' argument. This prevents anything
+- that follows from being interpreted as an option. It is only
+- set after argument parsing has proceeded past this point.
+-
+- `void *input'
+- An arbitrary pointer passed in from the caller of
+- `argp_parse', in the INPUT argument.
+-
+- `void **child_inputs'
+- These are values that will be passed to child parsers. This

+-
+-Combining Multiple Argp Parsers
+--------------------------------
+-
+- The `children' field in a `struct argp' enables other argp parsers
+-to be combined with the referencing one for the parsing of a single set
+-of arguments. This field should point to a vector of `struct
+-argp_child', which is terminated by an entry having a value of zero in
+-the `argp' field.
+-
+- Where conflicts between combined parsers arise, as when two specify
+-an option with the same name, the parser conflicts are resolved in
+-favor of the parent argp parser(s), or the earlier of the argp parsers
+-in the list of children.
+-
+- - Data Type: struct argp_child
+- An entry in the list of subsidiary argp parsers pointed to by the
+- `children' field in a `struct argp'. The fields are as follows:
+-
+- `const struct argp *argp'
+- The child argp parser, or zero to end of the list.
+-
+- `int flags'
+- Flags for this child.
+-
+- `const char *header'
+- If non-zero, this is an optional header to be printed within
+- help output before the child options. As a side-effect, a
+- non-zero value forces the child options to be grouped
+- together. To achieve this effect without actually printing a
+- header string, use a value of `""'. As with header strings
+- specified in an option entry, the conventional value of the
+- last character is `:'. *Note Argp Option Vectors::.
+-
+- `int group'
+- This is where the child options are grouped relative to the
+- other `consolidated' options in the parent argp parser. The
+- values are the same as the `group' field in `struct
+- argp_option'. *Note Argp Option Vectors::. All
+- child-groupings follow parent options at a particular group
+- level. If both this field and `header' are zero, then the
+- child's options aren't grouped together, they are merged with
+- parent options at the parent option group level.

+-
+-Flags for `argp_parse'
+-----------------------
+-
+- The default behavior of `argp_parse' is designed to be convenient
+-for the most common case of parsing program command line argument. To
+-modify these defaults, the following flags may be or'd together in the
+-FLAGS argument to `argp_parse':
+-
+-`ARGP_PARSE_ARGV0'
+- Don't ignore the first element of the ARGV argument to
+- `argp_parse'. Unless `ARGP_NO_ERRS' is set, the first element of
+- the argument vector is skipped for option parsing purposes, as it
+- corresponds to the program name in a command line.
+-
+-`ARGP_NO_ERRS'
+- Don't print error messages for unknown options to `stderr'; unless
+- this flag is set, `ARGP_PARSE_ARGV0' is ignored, as `argv[0]' is
+- used as the program name in the error messages. This flag implies
+- `ARGP_NO_EXIT'. This is based on the assumption that silent
+- exiting upon errors is bad behavior.
+-
+-`ARGP_NO_ARGS'
+- Don't parse any non-option args. Normally these are parsed by
+- calling the parse functions with a key of `ARGP_KEY_ARG', the
+- actual argument being the value. This flag needn't normally be
+- set, as the default behavior is to stop parsing as soon as an
+- argument fails to be parsed. *Note Argp Parser Functions::.
+-
+-`ARGP_IN_ORDER'
+- Parse options and arguments in the same order they occur on the
+- command line. Normally they're rearranged so that all options
+- come first.
+-
+-`ARGP_NO_HELP'
+- Don't provide the standard long option `--help', which ordinarily
+- causes usage and option help information to be output to `stdout'
+- and `exit (0)'.
+-
+-`ARGP_NO_EXIT'
+- Don't exit on errors, although they may still result in error
+- messages.
+-
+-`ARGP_LONG_ONLY'
+- Use the gnu getopt `long-only' rules for parsing arguments. This
+- allows long-options to be recognized with only a single `-' (i.e.
+- `-help'). This results in a less useful interface, and its use is
+- discouraged as it conflicts with the way most GNU programs work as
+- well as the GNU coding standards.
+-
+-`ARGP_SILENT'
+- Turns off any message-printing/exiting options, specifically
+- `ARGP_NO_EXIT', `ARGP_NO_ERRS', and `ARGP_NO_HELP'.

+-
+-Customizing Argp Help Output
+-----------------------------
+-
+- The `help_filter' field in a `struct argp' is a pointer to a
+-function that filters the text of help messages before displaying them.
+-They have a function signature like:
+-
+- char *HELP-FILTER (int KEY, const char *TEXT, void *INPUT)
+-
+-Where KEY is either a key from an option, in which case TEXT is that
+-option's help text. *Note Argp Option Vectors::. Alternately, one of
+-the special keys with names beginning with `ARGP_KEY_HELP_' might be
+-used, describing which other help text TEXT will contain. *Note Argp
+-Help Filter Keys::.
+-
+- The function should return either TEXT if it remains as-is, or a
+-replacement string allocated using `malloc'. This will be either be
+-freed by argp or zero, which prints nothing. The value of TEXT is
+-supplied _after_ any translation has been done, so if any of the
+-replacement text needs translation, it will be done by the filter
+-function. INPUT is either the input supplied to `argp_parse' or it is
+-zero, if `argp_help' was called directly by the user.

+-
+-`ARGP_KEY_HELP_EXTRA'

+-
+-The `argp_help' Function
+-------------------------
+-
+- Normally programs using argp need not be written with particular
+-printing argument-usage-type help messages in mind as the standard
+-`--help' option is handled automatically by argp. Typical error cases
+-can be handled using `argp_usage' and `argp_error'. *Note Argp Helper
+-Functions::. However, if it's desirable to print a help message in
+-some context other than parsing the program options, argp offers the
+-`argp_help' interface.
+-
+- - Function: void argp_help (const struct argp *ARGP, FILE *STREAM,
+- unsigned FLAGS, char *NAME)
+- This outputs a help message for the argp parser ARGP to STREAM.
+- The type of messages printed will be determined by FLAGS.
+-
+- Any options such as `--help' that are implemented automatically by
+- argp itself will _not_ be present in the help output; for this
+- reason it is best to use `argp_state_help' if calling from within
+- an argp parser function. *Note Argp Helper Functions::.

+-
+-Flags for the `argp_help' Function
+-----------------------------------
+-
+- When calling `argp_help' (*note Argp Help::) or `argp_state_help'
+-(*note Argp Helper Functions::) the exact output is determined by the
+-FLAGS argument. This should consist of any of the following flags,
+-or'd together:
+-
+-`ARGP_HELP_USAGE'
+- A unix `Usage:' message that explicitly lists all options.
+-
+-`ARGP_HELP_SHORT_USAGE'
+- A unix `Usage:' message that displays an appropriate placeholder to
+- indicate where the options go; useful for showing the non-option
+- argument syntax.
+-
+-`ARGP_HELP_SEE'
+- A `Try ... for more help' message; `...' contains the program name
+- and `--help'.
+-
+-`ARGP_HELP_LONG'
+- A verbose option help message that gives each option available
+- along with its documentation string.
+-
+-`ARGP_HELP_PRE_DOC'
+- The part of the argp parser doc string preceding the verbose
+- option help.
+-
+-`ARGP_HELP_POST_DOC'
+- The part of the argp parser doc string that following the verbose
+- option help.
+-
+-`ARGP_HELP_DOC'
+- `(ARGP_HELP_PRE_DOC | ARGP_HELP_POST_DOC)'
+-
+-`ARGP_HELP_BUG_ADDR'
+- A message that prints where to report bugs for this program, if the
+- `argp_program_bug_address' variable contains this information.
+-
+-`ARGP_HELP_LONG_ONLY'
+- This will modify any output to reflect the `ARGP_LONG_ONLY' mode.
+-
+- The following flags are only understood when used with
+-`argp_state_help'. They control whether the function returns after
+-printing its output, or terminates the program:
+-
+-`ARGP_HELP_EXIT_ERR'
+- This will terminate the program with `exit (argp_err_exit_status)'.
+-
+-`ARGP_HELP_EXIT_OK'
+- This will terminate the program with `exit (0)'.
+-
+- The following flags are combinations of the basic flags for printing
+-standard messages:
+-
+-`ARGP_HELP_STD_ERR'
+- Assuming that an error message for a parsing error has printed,
+- this prints a message on how to get help, and terminates the
+- program with an error.
+-
+-`ARGP_HELP_STD_USAGE'
+- This prints a standard usage message and terminates the program
+- with an error. This is used when no other specific error messages
+- are appropriate or available.
+-
+-`ARGP_HELP_STD_HELP'
+- This prints the standard response for a `--help' option, and
+- terminates the program successfully.

+-A Program Using Argp with Only Default Options
+-..............................................
+-
+- This program doesn't use any options or arguments, it uses argp to be
+-compliant with the GNU standard command line format.
+-
+- In addition to giving no arguments and implementing a `--help'
+-option, this example has a `--version' option, which will put the given
+-documentation string and bug address in the `--help' output, as per GNU
+-standards.
+-
+- The variable `argp' contains the argument parser specification.
+-Adding fields to this structure is the way most parameters are passed
+-to `argp_parse'. The first three fields are normally used, but they
+-are not in this small program. There are also two global variables
+-that argp can use defined here, `argp_program_version' and
+-`argp_program_bug_address'. They are considered global variables
+-because they will almost always be constant for a given program, even
+-if they use different argument parsers for various tasks.

+-A Program Using Argp with User Options
+-......................................
+-
+- This program uses the same features as example 2, adding user options
+-and arguments.
+-
+- We now use the first four fields in `argp' (*note Argp Parsers::)
+-and specify `parse_opt' as the parser function. *Note Argp Parser
+-Functions::.
+-
+- Note that in this example, `main' uses a structure to communicate
+-with the `parse_opt' function, a pointer to which it passes in the
+-`input' argument to `argp_parse'. *Note Argp::. It is retrieved by
+-`parse_opt' through the `input' field in its `state' argument. *Note
+-Argp Parsing State::. Of course, it's also possible to use global
+-variables instead, but using a structure like this is somewhat more
+-flexible and clean.
+-
+- /* Argp example #3 - a program with options and arguments using argp */
+-
+- /* This program uses the same features as example 2, and uses options and
+- arguments.
+-
+- We now use the first four fields in ARGP, so here's a description of them:
+- OPTIONS - A pointer to a vector of struct argp_option (see below)
+- PARSER - A function to parse a single option, called by argp
+- ARGS_DOC - A string describing how the non-option arguments should look
+- DOC - A descriptive string about this program; if it contains a
+- vertical tab character (\v), the part after it will be
+- printed *following* the options
+-
+- The function PARSER takes the following arguments:
+- KEY - An integer specifying which option this is (taken
+- from the KEY field in each struct argp_option), or
+- a special key specifying something else; the only
+- special keys we use here are ARGP_KEY_ARG, meaning
+- a non-option argument, and ARGP_KEY_END, meaning
+- that all arguments have been parsed
+- ARG - For an option KEY, the string value of its
+- argument, or NULL if it has none
+- STATE- A pointer to a struct argp_state, containing
+- various useful information about the parsing state; used here
+- are the INPUT field, which reflects the INPUT argument to
+- argp_parse, and the ARG_NUM field, which is the number of the
+- current non-option argument being parsed
+- It should return either 0, meaning success, ARGP_ERR_UNKNOWN, meaning the
+- given KEY wasn't recognized, or an errno value indicating some other
+- error.
+-
+- Note that in this example, main uses a structure to communicate with the
+- parse_opt function, a pointer to which it passes in the INPUT argument to
+- argp_parse. Of course, it's also possible to use global variables
+- instead, but this is somewhat more flexible.
+-
+- The OPTIONS field contains a pointer to a vector of struct argp_option's;
+- that structure has the following fields (if you assign your option
+- structures using array initialization like this example, unspecified
+- fields will be defaulted to 0, and need not be specified):
+- NAME - The name of this option's long option (may be zero)
+- KEY - The KEY to pass to the PARSER function when parsing this option,
+- *and* the name of this option's short option, if it is a
+- printable ascii character
+- ARG - The name of this option's argument, if any
+- FLAGS - Flags describing this option; some of them are:
+- OPTION_ARG_OPTIONAL - The argument to this option is optional
+- OPTION_ALIAS - This option is an alias for the
+- previous option
+- OPTION_HIDDEN - Don't show this option in -help output
+- DOC - A documentation string for this option, shown in -help output
+-
+- An options vector should be terminated by an option with all fields zero. */

+-A Program Using Multiple Combined Argp Parsers
+-..............................................
+-
+- This program uses the same features as example 3, but has more
+-options, and presents more structure in the `--help' output. It also
+-illustrates how you can `steal' the remainder of the input arguments
+-past a certain point for programs that accept a list of items. It also
+-illustrates the KEY value `ARGP_KEY_NO_ARGS', which is only given if no
+-non-option arguments were supplied to the program. *Note Argp Special
+-Keys::.
+-
+- For structuring help output, two features are used: _headers_ and a
+-two part option string. The _headers_ are entries in the options
+-vector. *Note Argp Option Vectors::. The first four fields are zero.
+-The two part documentation string are in the variable `doc', which
+-allows documentation both before and after the options. *Note Argp
+-Parsers::, the two parts of `doc' are separated by a vertical-tab
+-character (`'\v'', or `'\013''). By convention, the documentation
+-before the options is a short string stating what the program does, and
+-after any options it is longer, describing the behavior in more detail.
+-All documentation strings are automatically filled for output,
+-although newlines may be included to force a line break at a particular
+-point. In addition, documentation strings are passed to the `gettext'
+-function, for possible translation into the current locale.
+-
+- /* Argp example #4 - a program with somewhat more complicated options */

+-Parsing of Suboptions
+-.....................
+-
+- Having a single level of options is sometimes not enough. There
+-might be too many options which have to be available or a set of
+-options is closely related.
+-
+- For this case some programs use suboptions. One of the most
+-prominent programs is certainly `mount'(8). The `-o' option take one
+-argument which itself is a comma separated list of options. To ease the
+-programming of code like this the function `getsubopt' is available.
+-
+- - Function: int getsubopt (char **OPTIONP, const char* const *TOKENS,
+- char **VALUEP)
+- The OPTIONP parameter must be a pointer to a variable containing
+- the address of the string to process. When the function returns
+- the reference is updated to point to the next suboption or to the
+- terminating `\0' character if there is no more suboption available.
+-
+- The TOKENS parameter references an array of strings containing the
+- known suboptions. All strings must be `\0' terminated and to mark
+- the end a null pointer must be stored. When `getsubopt' finds a
+- possible legal suboption it compares it with all strings available
+- in the TOKENS array and returns the index in the string as the
+- indicator.
+-
+- In case the suboption has an associated value introduced by a `='
+- character, a pointer to the value is returned in VALUEP. The
+- string is `\0' terminated. If no argument is available VALUEP is
+- set to the null pointer. By doing this the caller can check
+- whether a necessary value is given or whether no unexpected value
+- is present.
+-
+- In case the next suboption in the string is not mentioned in the
+- TOKENS array the starting address of the suboption including a
+- possible value is returned in VALUEP and the return value of the
+- function is `-1'.

+-Environment Variables
+-=====================
+-
+- When a program is executed, it receives information about the
+-context in which it was invoked in two ways. The first mechanism uses
+-the ARGV and ARGC arguments to its `main' function, and is discussed in
+-*Note Program Arguments::. The second mechanism uses "environment
+-variables" and is discussed in this section.
+-
+- The ARGV mechanism is typically used to pass command-line arguments
+-specific to the particular program being invoked. The environment, on
+-the other hand, keeps track of information that is shared by many
+-programs, changes infrequently, and that is less frequently used.
+-
+- The environment variables discussed in this section are the same
+-environment variables that you set using assignments and the `export'
+-command in the shell. Programs executed from the shell inherit all of
+-the environment variables from the shell.
+-
+- Standard environment variables are used for information about the
+-user's home directory, terminal type, current locale, and so on; you
+-can define additional variables for other purposes. The set of all
+-environment variables that have values is collectively known as the
+-"environment".
+-
+- Names of environment variables are case-sensitive and must not
+-contain the character `='. System-defined environment variables are
+-invariably uppercase.
+-
+- The values of environment variables can be anything that can be
+-represented as a string. A value must not contain an embedded null
+-character, since this is assumed to terminate the string.
+-
+-* Menu:
+-
+-* Environment Access:: How to get and set the values of
+- environment variables.
+-* Standard Environment:: These environment variables have
+- standard interpretations.
+-
+-\1f
+-File: libc.info, Node: Environment Access, Next: Standard Environment, Up: Environment Variables
+-
+-Environment Access
+-------------------
+-
+- The value of an environment variable can be accessed with the
+-`getenv' function. This is declared in the header file `stdlib.h'.
+-All of the following functions can be safely used in multi-threaded
+-programs. It is made sure that concurrent modifications to the
+-environment do not lead to errors.
+-
+- - Function: char * getenv (const char *NAME)
+- This function returns a string that is the value of the environment
+- variable NAME. You must not modify this string. In some non-Unix
+- systems not using the GNU library, it might be overwritten by
+- subsequent calls to `getenv' (but not by any other library
+- function). If the environment variable NAME is not defined, the
+- value is a null pointer.
+-
+- - Function: int putenv (char *STRING)
+- The `putenv' function adds or removes definitions from the
+- environment. If the STRING is of the form `NAME=VALUE', the
+- definition is added to the environment. Otherwise, the STRING is
+- interpreted as the name of an environment variable, and any
+- definition for this variable in the environment is removed.
+-
+- The difference to the `setenv' function is that the exact string
+- given as the parameter STRING is put into the environment. If the
+- user should change the string after the `putenv' call this will
+- reflect in automatically in the environment. This also requires
+- that STRING is no automatic variable which scope is left before the
+- variable is removed from the environment. The same applies of
+- course to dynamically allocated variables which are freed later.
+-
+- This function is part of the extended Unix interface. Since it
+- was also available in old SVID libraries you should define either
+- _XOPEN_SOURCE or _SVID_SOURCE before including any header.
+-
+- - Function: int setenv (const char *NAME, const char *VALUE, int
+- REPLACE)
+- The `setenv' function can be used to add a new definition to the
+- environment. The entry with the name NAME is replaced by the
+- value `NAME=VALUE'. Please note that this is also true if VALUE
+- is the empty string. To do this a new string is created and the
+- strings NAME and VALUE are copied. A null pointer for the VALUE
+- parameter is illegal. If the environment already contains an
+- entry with key NAME the REPLACE parameter controls the action. If
+- replace is zero, nothing happens. Otherwise the old entry is
+- replaced by the new one.
+-
+- Please note that you cannot remove an entry completely using this
+- function.
+-
+- This function was originally part of the BSD library but is now
+- part of the Unix standard.
+-
+- - Function: int unsetenv (const char *NAME)
+- Using this function one can remove an entry completely from the
+- environment. If the environment contains an entry with the key
+- NAME this whole entry is removed. A call to this function is
+- equivalent to a call to `putenv' when the VALUE part of the string
+- is empty.
+-
+- The function return `-1' if NAME is a null pointer, points to an
+- empty string, or points to a string containing a `=' character.
+- It returns `0' if the call succeeded.
+-
+- This function was originally part of the BSD library but is now
+- part of the Unix standard. The BSD version had no return value,
+- though.
+-
+- There is one more function to modify the whole environment. This
+-function is said to be used in the POSIX.9 (POSIX bindings for Fortran
+-77) and so one should expect it did made it into POSIX.1. But this
+-never happened. But we still provide this function as a GNU extension
+-to enable writing standard compliant Fortran environments.
+-
+- - Function: int clearenv (void)
+- The `clearenv' function removes all entries from the environment.
+- Using `putenv' and `setenv' new entries can be added again later.
+-
+- If the function is successful it returns `0'. Otherwise the return
+- value is nonzero.
+-
+- You can deal directly with the underlying representation of
+-environment objects to add more variables to the environment (for
+-example, to communicate with another program you are about to execute;
+-*note Executing a File::).
+-
+- - Variable: char ** environ
+- The environment is represented as an array of strings. Each
+- string is of the format `NAME=VALUE'. The order in which strings
+- appear in the environment is not significant, but the same NAME
+- must not appear more than once. The last element of the array is
+- a null pointer.
+-
+- This variable is declared in the header file `unistd.h'.
+-
+- If you just want to get the value of an environment variable, use
+- `getenv'.
+-
+- Unix systems, and the GNU system, pass the initial value of
+-`environ' as the third argument to `main'. *Note Program Arguments::.

+-
+-Standard Environment Variables
+-------------------------------
+-
+- These environment variables have standard meanings. This doesn't
+-mean that they are always present in the environment; but if these
+-variables _are_ present, they have these meanings. You shouldn't try
+-to use these environment variable names for some other purpose.
+-
+-`HOME'
+- This is a string representing the user's "home directory", or
+- initial default working directory.
+-
+- The user can set `HOME' to any value. If you need to make sure to
+- obtain the proper home directory for a particular user, you should
+- not use `HOME'; instead, look up the user's name in the user
+- database (*note User Database::).
+-
+- For most purposes, it is better to use `HOME', precisely because
+- this lets the user specify the value.
+-
+-`LOGNAME'
+- This is the name that the user used to log in. Since the value in
+- the environment can be tweaked arbitrarily, this is not a reliable
+- way to identify the user who is running a program; a function like
+- `getlogin' (*note Who Logged In::) is better for that purpose.
+-
+- For most purposes, it is better to use `LOGNAME', precisely because
+- this lets the user specify the value.
+-
+-`PATH'
+- A "path" is a sequence of directory names which is used for
+- searching for a file. The variable `PATH' holds a path used for
+- searching for programs to be run.
+-
+- The `execlp' and `execvp' functions (*note Executing a File::) use
+- this environment variable, as do many shells and other utilities
+- which are implemented in terms of those functions.
+-
+- The syntax of a path is a sequence of directory names separated by
+- colons. An empty string instead of a directory name stands for the
+- current directory (*note Working Directory::).
+-
+- A typical value for this environment variable might be a string
+- like:
+-
+- :/bin:/etc:/usr/bin:/usr/new/X11:/usr/new:/usr/local/bin
+-
+- This means that if the user tries to execute a program named `foo',
+- the system will look for files named `foo', `/bin/foo',
+- `/etc/foo', and so on. The first of these files that exists is
+- the one that is executed.
+-
+-`TERM'
+- This specifies the kind of terminal that is receiving program
+- output. Some programs can make use of this information to take
+- advantage of special escape sequences or terminal modes supported
+- by particular kinds of terminals. Many programs which use the
+- termcap library (*note Find: (termcap)Finding a Terminal
+- Description.) use the `TERM' environment variable, for example.
+-
+-`TZ'
+- This specifies the time zone. *Note TZ Variable::, for
+- information about the format of this string and how it is used.
+-
+-`LANG'
+- This specifies the default locale to use for attribute categories
+- where neither `LC_ALL' nor the specific environment variable for
+- that category is set. *Note Locales::, for more information about
+- locales.
+-
+-`LC_ALL'
+- If this environment variable is set it overrides the selection for
+- all the locales done using the other `LC_*' environment variables.
+- The value of the other `LC_*' environment variables is simply
+- ignored in this case.
+-
+-`LC_COLLATE'
+- This specifies what locale to use for string sorting.
+-
+-`LC_CTYPE'
+- This specifies what locale to use for character sets and character
+- classification.
+-
+-`LC_MESSAGES'
+- This specifies what locale to use for printing messages and to
+- parse responses.
+-
+-`LC_MONETARY'
+- This specifies what locale to use for formatting monetary values.
+-
+-`LC_NUMERIC'
+- This specifies what locale to use for formatting numbers.
+-
+-`LC_TIME'
+- This specifies what locale to use for formatting date/time values.
+-
+-`NLSPATH'
+- This specifies the directories in which the `catopen' function
+- looks for message translation catalogs.
+-
+-`_POSIX_OPTION_ORDER'
+- If this environment variable is defined, it suppresses the usual
+- reordering of command line arguments by `getopt' and `argp_parse'.

+-
+-System Calls
+-============
+-
+- A system call is a request for service that a program makes of the
+-kernel. The service is generally something that only the kernel has
+-the privilege to do, such as doing I/O. Programmers don't normally
+-need to be concerned with system calls because there are functions in
+-the GNU C library to do virtually everything that system calls do.
+-These functions work by making system calls themselves. For example,
+-there is a system call that changes the permissions of a file, but you
+-don't need to know about it because you can just use the GNU C
+-library's `chmod' function.
+-
+- System calls are sometimes called kernel calls.
+-
+- However, there are times when you want to make a system call
+-explicitly, and for that, the GNU C library provides the `syscall'
+-function. `syscall' is harder to use and less portable than functions
+-like `chmod', but easier and more portable than coding the system call
+-in assembler instructions.
+-
+- `syscall' is most useful when you are working with a system call
+-which is special to your system or is newer than the GNU C library you
+-are using. `syscall' is implemented in an entirely generic way; the
+-function does not know anything about what a particular system call
+-does or even if it is valid.
+-
+- The description of `syscall' in this section assumes a certain
+-protocol for system calls on the various platforms on which the GNU C
+-library runs. That protocol is not defined by any strong authority, but
+-we won't describe it here either because anyone who is coding `syscall'
+-probably won't accept anything less than kernel and C library source
+-code as a specification of the interface between them anyway.
+-
+- `syscall' is declared in `unistd.h'.
+-
+- - Function: long int syscall (long int SYSNO, ...)
+- `syscall' performs a generic system call.
+-
+- SYSNO is the system call number. Each kind of system call is
+- identified by a number. Macros for all the possible system call
+- numbers are defined in `sys/syscall.h'
+-
+- The remaining arguments are the arguments for the system call, in
+- order, and their meanings depend on the kind of system call. Each
+- kind of system call has a definite number of arguments, from zero
+- to five. If you code more arguments than the system call takes,
+- the extra ones to the right are ignored.
+-
+- The return value is the return value from the system call, unless
+- the system call failed. In that case, `syscall' returns `-1' and
+- sets `errno' to an error code that the system call returned. Note
+- that system calls do not return `-1' when they succeed.
+-
+- If you specify an invalid SYSNO, `syscall' returns `-1' with
+- `errno' = `ENOSYS'.
+-
+- Example:
+-
+-
+- #include <unistd.h>
+- #include <sys/syscall.h>
+- #include <errno.h>
+-
+- ...
+-
+- int rc;
+-
+- rc = syscall(SYS_chmod, "/etc/passwd", 0444);
+-
+- if (rc == -1)
+- fprintf(stderr, "chmod failed, errno = %d\n", errno);
+-
+- This, if all the compatibility stars are aligned, is equivalent to
+- the following preferable code:
+-
+-
+- #include <sys/types.h>
+- #include <sys/stat.h>
+- #include <errno.h>
+-
+- ...
+-
+- int rc;
+-
+- rc = chmod("/etc/passwd", 0444);
+- if (rc == -1)
+- fprintf(stderr, "chmod failed, errno = %d\n", errno);

+-Program Termination
+-===================
+-
+- The usual way for a program to terminate is simply for its `main'
+-function to return. The "exit status value" returned from the `main'
+-function is used to report information back to the process's parent
+-process or shell.
+-
+- A program can also terminate normally by calling the `exit' function.
+-
+- In addition, programs can be terminated by signals; this is
+-discussed in more detail in *Note Signal Handling::. The `abort'
+-function causes a signal that kills the program.

+-
+-Normal Termination
+-------------------
+-
+- A process terminates normally when its program signals it is done by
+-calling `exit'. Returning from `main' is equivalent to calling `exit',
+-and the value that `main' returns is used as the argument to `exit'.
+-
+- - Function: void exit (int STATUS)
+- The `exit' function tells the system that the program is done,
+- which causes it to terminate the process.
+-
+- STATUS is the program's exit status, which becomes part of the
+- process' termination status. This function does not return.
+-
+- Normal termination causes the following actions:
+-
+- 1. Functions that were registered with the `atexit' or `on_exit'
+- functions are called in the reverse order of their registration.
+- This mechanism allows your application to specify its own
+- "cleanup" actions to be performed at program termination.
+- Typically, this is used to do things like saving program state
+- information in a file, or unlocking locks in shared data bases.
+-
+- 2. All open streams are closed, writing out any buffered output data.
+- See *Note Closing Streams::. In addition, temporary files opened
+- with the `tmpfile' function are removed; see *Note Temporary
+- Files::.
+-
+- 3. `_exit' is called, terminating the program. *Note Termination
+- Internals::.

+-File: libc.info, Node: Exit Status, Next: Cleanups on Exit, Prev: Normal Termination, Up: Program Termination
+-
+-Exit Status
+------------
+-
+- When a program exits, it can return to the parent process a small
+-amount of information about the cause of termination, using the "exit
+-status". This is a value between 0 and 255 that the exiting process
+-passes as an argument to `exit'.
+-
+- Normally you should use the exit status to report very broad
+-information about success or failure. You can't provide a lot of
+-detail about the reasons for the failure, and most parent processes
+-would not want much detail anyway.
+-
+- There are conventions for what sorts of status values certain
+-programs should return. The most common convention is simply 0 for
+-success and 1 for failure. Programs that perform comparison use a
+-different convention: they use status 1 to indicate a mismatch, and
+-status 2 to indicate an inability to compare. Your program should
+-follow an existing convention if an existing convention makes sense for
+-it.
+-
+- A general convention reserves status values 128 and up for special
+-purposes. In particular, the value 128 is used to indicate failure to
+-execute another program in a subprocess. This convention is not
+-universally obeyed, but it is a good idea to follow it in your programs.
+-
+- *Warning:* Don't try to use the number of errors as the exit status.
+-This is actually not very useful; a parent process would generally not
+-care how many errors occurred. Worse than that, it does not work,
+-because the status value is truncated to eight bits. Thus, if the
+-program tried to report 256 errors, the parent would receive a report
+-of 0 errors--that is, success.
+-
+- For the same reason, it does not work to use the value of `errno' as
+-the exit status--these can exceed 255.
+-
+- *Portability note:* Some non-POSIX systems use different conventions
+-for exit status values. For greater portability, you can use the
+-macros `EXIT_SUCCESS' and `EXIT_FAILURE' for the conventional status
+-value for success and failure, respectively. They are declared in the
+-file `stdlib.h'.
+-
+- - Macro: int EXIT_SUCCESS
+- This macro can be used with the `exit' function to indicate
+- successful program completion.
+-
+- On POSIX systems, the value of this macro is `0'. On other
+- systems, the value might be some other (possibly non-constant)
+- integer expression.
+-
+- - Macro: int EXIT_FAILURE
+- This macro can be used with the `exit' function to indicate
+- unsuccessful program completion in a general sense.
+-
+- On POSIX systems, the value of this macro is `1'. On other
+- systems, the value might be some other (possibly non-constant)
+- integer expression. Other nonzero status values also indicate
+- failures. Certain programs use different nonzero status values to
+- indicate particular kinds of "non-success". For example, `diff'
+- uses status value `1' to mean that the files are different, and
+- `2' or more to mean that there was difficulty in opening the files.
+-
+- Don't confuse a program's exit status with a process' termination
+-status. There are lots of ways a process can terminate besides having
+-it's program finish. In the event that the process termination _is_
+-caused by program termination (i.e. `exit'), though, the program's exit
+-status becomes part of the process' termination status.

+-Cleanups on Exit
+-----------------
+-
+- Your program can arrange to run its own cleanup functions if normal
+-termination happens. If you are writing a library for use in various
+-application programs, then it is unreliable to insist that all
+-applications call the library's cleanup functions explicitly before
+-exiting. It is much more robust to make the cleanup invisible to the
+-application, by setting up a cleanup function in the library itself
+-using `atexit' or `on_exit'.
+-
+- - Function: int atexit (void (*FUNCTION) (void))
+- The `atexit' function registers the function FUNCTION to be called
+- at normal program termination. The FUNCTION is called with no
+- arguments.
+-
+- The return value from `atexit' is zero on success and nonzero if
+- the function cannot be registered.
+-
+- - Function: int on_exit (void (*FUNCTION)(int STATUS, void *ARG), void
+- *ARG)
+- This function is a somewhat more powerful variant of `atexit'. It
+- accepts two arguments, a function FUNCTION and an arbitrary
+- pointer ARG. At normal program termination, the FUNCTION is
+- called with two arguments: the STATUS value passed to `exit', and
+- the ARG.
+-
+- This function is included in the GNU C library only for
+- compatibility for SunOS, and may not be supported by other
+- implementations.
+-
+- Here's a trivial program that illustrates the use of `exit' and
+-`atexit':
+-
+- #include <stdio.h>
+- #include <stdlib.h>
+-
+- void
+- bye (void)
+- {
+- puts ("Goodbye, cruel world....");
+- }
+-
+- int
+- main (void)
+- {
+- atexit (bye);
+- exit (EXIT_SUCCESS);
+- }
+-
+-When this program is executed, it just prints the message and exits.

+-
+-Aborting a Program
+-------------------
+-
+- You can abort your program using the `abort' function. The prototype
+-for this function is in `stdlib.h'.
+-
+- - Function: void abort (void)
+- The `abort' function causes abnormal program termination. This
+- does not execute cleanup functions registered with `atexit' or
+- `on_exit'.
+-
+- This function actually terminates the process by raising a
+- `SIGABRT' signal, and your program can include a handler to
+- intercept this signal; see *Note Signal Handling::.
+-
+- *Future Change Warning:* Proposed Federal censorship regulations may
+-prohibit us from giving you information about the possibility of
+-calling this function. We would be required to say that this is not an
+-acceptable way of terminating a program.

+-Termination Internals
+----------------------
+-
+- The `_exit' function is the primitive used for process termination
+-by `exit'. It is declared in the header file `unistd.h'.
+-
+- - Function: void _exit (int STATUS)
+- The `_exit' function is the primitive for causing a process to
+- terminate with status STATUS. Calling this function does not
+- execute cleanup functions registered with `atexit' or `on_exit'.
+-
+- - Function: void _Exit (int STATUS)
+- The `_Exit' function is the ISO C equivalent to `_exit'. The
+- ISO C committee members were not sure whether the definitions of
+- `_exit' and `_Exit' were compatible so they have not used the
+- POSIX name.
+-
+- This function was introduced in ISO C99 and is declared in
+- `stdlib.h'.
+-
+- When a process terminates for any reason--either because the program
+-terminates, or as a result of a signal--the following things happen:
+-
+- * All open file descriptors in the process are closed. *Note
+- Low-Level I/O::. Note that streams are not flushed automatically
+- when the process terminates; see *Note I/O on Streams::.
+-
+- * A process exit status is saved to be reported back to the parent
+- process via `wait' or `waitpid'; see *Note Process Completion::.
+- If the program exited, this status includes as its low-order 8
+- bits the program exit status.
+-
+- * Any child processes of the process being terminated are assigned a
+- new parent process. (On most systems, including GNU, this is the
+- `init' process, with process ID 1.)
+-
+- * A `SIGCHLD' signal is sent to the parent process.

+- * If the process is a session leader that has a controlling
+- terminal, then a `SIGHUP' signal is sent to each process in the

+- that session. *Note Job Control::.

+-Processes
+-*********
+-
+- "Processes" are the primitive units for allocation of system
+-resources. Each process has its own address space and (usually) one
+-thread of control. A process executes a program; you can have multiple
+-processes executing the same program, but each process has its own copy
+-of the program within its own address space and executes it
+-independently of the other copies.
+-
+- Processes are organized hierarchically. Each process has a "parent
+-process" which explicitly arranged to create it. The processes created
+-by a given parent are called its "child processes". A child inherits
+-many of its attributes from the parent process.
+-
+- This chapter describes how a program can create, terminate, and
+-control child processes. Actually, there are three distinct operations
+-involved: creating a new child process, causing the new process to
+-execute a program, and coordinating the completion of the child process
+-with the original program.
+-
+- The `system' function provides a simple, portable mechanism for
+-running another program; it does all three steps automatically. If you
+-need more control over the details of how this is done, you can use the
+-primitive functions to do each step individually instead.

+-
+-Running a Command
+-=================
+-
+- The easy way to run another program is to use the `system' function.
+-This function does all the work of running a subprogram, but it
+-doesn't give you much control over the details: you have to wait until
+-the subprogram terminates before you can do anything else.
+-
+- - Function: int system (const char *COMMAND)
+- This function executes COMMAND as a shell command. In the GNU C
+- library, it always uses the default shell `sh' to run the command.
+- In particular, it searches the directories in `PATH' to find
+- programs to execute. The return value is `-1' if it wasn't
+- possible to create the shell process, and otherwise is the status
+- of the shell process. *Note Process Completion::, for details on
+- how this status code can be interpreted.
+-
+- If the COMMAND argument is a null pointer, a return value of zero
+- indicates that no command processor is available.
+-
+- This function is a cancellation point in multi-threaded programs.
+- This is a problem if the thread allocates some resources (like
+- memory, file descriptors, semaphores or whatever) at the time
+- `system' is called. If the thread gets canceled these resources
+- stay allocated until the program ends. To avoid this calls to
+- `system' should be protected using cancellation handlers.
+-
+- The `system' function is declared in the header file `stdlib.h'.
+-
+- *Portability Note:* Some C implementations may not have any notion
+-of a command processor that can execute other programs. You can
+-determine whether a command processor exists by executing
+-`system (NULL)'; if the return value is nonzero, a command processor is
+-available.
+-
+- The `popen' and `pclose' functions (*note Pipe to a Subprocess::)
+-are closely related to the `system' function. They allow the parent
+-process to communicate with the standard input and output channels of
+-the command being executed.

+-
+-Process Creation Concepts
+-=========================
+-
+- This section gives an overview of processes and of the steps
+-involved in creating a process and making it run another program.
+-
+- Each process is named by a "process ID" number. A unique process ID
+-is allocated to each process when it is created. The "lifetime" of a
+-process ends when its termination is reported to its parent process; at
+-that time, all of the process resources, including its process ID, are
+-freed.
+-
+- Processes are created with the `fork' system call (so the operation
+-of creating a new process is sometimes called "forking" a process).
+-The "child process" created by `fork' is a copy of the original "parent
+-process", except that it has its own process ID.
+-
+- After forking a child process, both the parent and child processes
+-continue to execute normally. If you want your program to wait for a
+-child process to finish executing before continuing, you must do this
+-explicitly after the fork operation, by calling `wait' or `waitpid'
+-(*note Process Completion::). These functions give you limited
+-information about why the child terminated--for example, its exit
+-status code.
+-
+- A newly forked child process continues to execute the same program as
+-its parent process, at the point where the `fork' call returns. You
+-can use the return value from `fork' to tell whether the program is
+-running in the parent process or the child.
+-
+- Having several processes run the same program is only occasionally
+-useful. But the child can execute another program using one of the
+-`exec' functions; see *Note Executing a File::. The program that the
+-process is executing is called its "process image". Starting execution
+-of a new program causes the process to forget all about its previous
+-process image; when the new program exits, the process exits too,
+-instead of returning to the previous process image.

+-
+-Process Identification
+-======================
+-
+- The `pid_t' data type represents process IDs. You can get the
+-process ID of a process by calling `getpid'. The function `getppid'
+-returns the process ID of the parent of the current process (this is
+-also known as the "parent process ID"). Your program should include
+-the header files `unistd.h' and `sys/types.h' to use these functions.
+-
+- - Data Type: pid_t
+- The `pid_t' data type is a signed integer type which is capable of
+- representing a process ID. In the GNU library, this is an `int'.
+-
+- - Function: pid_t getpid (void)
+- The `getpid' function returns the process ID of the current
+- process.
+-
+- - Function: pid_t getppid (void)
+- The `getppid' function returns the process ID of the parent of the
+- current process.
+-
+-\1f
+-File: libc.info, Node: Creating a Process, Next: Executing a File, Prev: Process Identification, Up: Processes
+-
+-Creating a Process
+-==================
+-
+- The `fork' function is the primitive for creating a process. It is
+-declared in the header file `unistd.h'.
+-
+- - Function: pid_t fork (void)
+- The `fork' function creates a new process.
+-
+- If the operation is successful, there are then both parent and
+- child processes and both see `fork' return, but with different
+- values: it returns a value of `0' in the child process and returns
+- the child's process ID in the parent process.
+-
+- If process creation failed, `fork' returns a value of `-1' in the
+- parent process. The following `errno' error conditions are
+- defined for `fork':
+-
+- `EAGAIN'
+- There aren't enough system resources to create another
+- process, or the user already has too many processes running.
+- This means exceeding the `RLIMIT_NPROC' resource limit, which
+- can usually be increased; *note Limits on Resources::.
+-
+- `ENOMEM'
+- The process requires more space than the system can supply.
+-
+- The specific attributes of the child process that differ from the
+-parent process are:
+-
+- * The child process has its own unique process ID.
+-
+- * The parent process ID of the child process is the process ID of its
+- parent process.
+-
+- * The child process gets its own copies of the parent process's open
+- file descriptors. Subsequently changing attributes of the file
+- descriptors in the parent process won't affect the file
+- descriptors in the child, and vice versa. *Note Control
+- Operations::. However, the file position associated with each
+- descriptor is shared by both processes; *note File Position::.
+-
+- * The elapsed processor times for the child process are set to zero;
+- see *Note Processor Time::.
+-
+- * The child doesn't inherit file locks set by the parent process.
+- *Note Control Operations::.
+-
+- * The child doesn't inherit alarms set by the parent process. *Note
+- Setting an Alarm::.
+-
+- * The set of pending signals (*note Delivery of Signal::) for the
+- child process is cleared. (The child process inherits its mask of
+- blocked signals and signal actions from the parent process.)
+-
+- - Function: pid_t vfork (void)
+- The `vfork' function is similar to `fork' but on some systems it
+- is more efficient; however, there are restrictions you must follow
+- to use it safely.
+-
+- While `fork' makes a complete copy of the calling process's address
+- space and allows both the parent and child to execute
+- independently, `vfork' does not make this copy. Instead, the
+- child process created with `vfork' shares its parent's address
+- space until it calls `_exit' or one of the `exec' functions. In
+- the meantime, the parent process suspends execution.
+-
+- You must be very careful not to allow the child process created
+- with `vfork' to modify any global data or even local variables
+- shared with the parent. Furthermore, the child process cannot
+- return from (or do a long jump out of) the function that called
+- `vfork'! This would leave the parent process's control
+- information very confused. If in doubt, use `fork' instead.
+-
+- Some operating systems don't really implement `vfork'. The GNU C
+- library permits you to use `vfork' on all systems, but actually
+- executes `fork' if `vfork' isn't available. If you follow the
+- proper precautions for using `vfork', your program will still work
+- even if the system uses `fork' instead.

+-
+-Executing a File
+-================
+-
+- This section describes the `exec' family of functions, for executing
+-a file as a process image. You can use these functions to make a child
+-process execute a new program after it has been forked.
+-
+- To see the effects of `exec' from the point of view of the called
+-program, *Note Program Basics::.
+-
+- The functions in this family differ in how you specify the arguments,
+-but otherwise they all do the same thing. They are declared in the
+-header file `unistd.h'.
+-
+- - Function: int execv (const char *FILENAME, char *const ARGV[])
+- The `execv' function executes the file named by FILENAME as a new
+- process image.
+-
+- The ARGV argument is an array of null-terminated strings that is
+- used to provide a value for the `argv' argument to the `main'
+- function of the program to be executed. The last element of this
+- array must be a null pointer. By convention, the first element of
+- this array is the file name of the program sans directory names.
+- *Note Program Arguments::, for full details on how programs can
+- access these arguments.
+-
+- The environment for the new process image is taken from the
+- `environ' variable of the current process image; see *Note
+- Environment Variables::, for information about environments.
+-
+- - Function: int execl (const char *FILENAME, const char *ARG0, ...)
+- This is similar to `execv', but the ARGV strings are specified
+- individually instead of as an array. A null pointer must be
+- passed as the last such argument.
+-
+- - Function: int execve (const char *FILENAME, char *const ARGV[], char
+- *const ENV[])
+- This is similar to `execv', but permits you to specify the
+- environment for the new program explicitly as the ENV argument.
+- This should be an array of strings in the same format as for the
+- `environ' variable; see *Note Environment Access::.
+-
+- - Function: int execle (const char *FILENAME, const char *ARG0, char
+- *const ENV[], ...)
+- This is similar to `execl', but permits you to specify the
+- environment for the new program explicitly. The environment
+- argument is passed following the null pointer that marks the last
+- ARGV argument, and should be an array of strings in the same
+- format as for the `environ' variable.
+-
+- - Function: int execvp (const char *FILENAME, char *const ARGV[])
+- The `execvp' function is similar to `execv', except that it
+- searches the directories listed in the `PATH' environment variable
+- (*note Standard Environment::) to find the full file name of a
+- file from FILENAME if FILENAME does not contain a slash.
+-
+- This function is useful for executing system utility programs,
+- because it looks for them in the places that the user has chosen.
+- Shells use it to run the commands that users type.
+-
+- - Function: int execlp (const char *FILENAME, const char *ARG0, ...)
+- This function is like `execl', except that it performs the same
+- file name searching as the `execvp' function.
+-
+- The size of the argument list and environment list taken together
+-must not be greater than `ARG_MAX' bytes. *Note General Limits::. In
+-the GNU system, the size (which compares against `ARG_MAX') includes,
+-for each string, the number of characters in the string, plus the size
+-of a `char *', plus one, rounded up to a multiple of the size of a
+-`char *'. Other systems may have somewhat different rules for counting.
+-
+- These functions normally don't return, since execution of a new
+-program causes the currently executing program to go away completely.
+-A value of `-1' is returned in the event of a failure. In addition to
+-the usual file name errors (*note File Name Errors::), the following
+-`errno' error conditions are defined for these functions:
+-
+-`E2BIG'
+- The combined size of the new program's argument list and
+- environment list is larger than `ARG_MAX' bytes. The GNU system
+- has no specific limit on the argument list size, so this error
+- code cannot result, but you may get `ENOMEM' instead if the
+- arguments are too big for available memory.
+-
+-`ENOEXEC'
+- The specified file can't be executed because it isn't in the right
+- format.
+-
+-`ENOMEM'
+- Executing the specified file requires more storage than is
+- available.
+-
+- If execution of the new file succeeds, it updates the access time
+-field of the file as if the file had been read. *Note File Times::,
+-for more details about access times of files.
+-
+- The point at which the file is closed again is not specified, but is
+-at some point before the process exits or before another process image
+-is executed.
+-
+- Executing a new process image completely changes the contents of
+-memory, copying only the argument and environment strings to new
+-locations. But many other attributes of the process are unchanged:
+-
+- * The process ID and the parent process ID. *Note Process Creation
+- Concepts::.
+-
+- * Session and process group membership. *Note Concepts of Job
+- Control::.
+-
+- * Real user ID and group ID, and supplementary group IDs. *Note
+- Process Persona::.
+-
+- * Pending alarms. *Note Setting an Alarm::.
+-
+- * Current working directory and root directory. *Note Working
+- Directory::. In the GNU system, the root directory is not copied
+- when executing a setuid program; instead the system default root
+- directory is used for the new program.
+-
+- * File mode creation mask. *Note Setting Permissions::.
+-
+- * Process signal mask; see *Note Process Signal Mask::.
+-
+- * Pending signals; see *Note Blocking Signals::.
+-
+- * Elapsed processor time associated with the process; see *Note
+- Processor Time::.
+-
+- If the set-user-ID and set-group-ID mode bits of the process image
+-file are set, this affects the effective user ID and effective group ID
+-(respectively) of the process. These concepts are discussed in detail
+-in *Note Process Persona::.
+-
+- Signals that are set to be ignored in the existing process image are
+-also set to be ignored in the new process image. All other signals are
+-set to the default action in the new process image. For more
+-information about signals, see *Note Signal Handling::.
+-
+- File descriptors open in the existing process image remain open in
+-the new process image, unless they have the `FD_CLOEXEC'
+-(close-on-exec) flag set. The files that remain open inherit all
+-attributes of the open file description from the existing process image,
+-including file locks. File descriptors are discussed in *Note
+-Low-Level I/O::.
+-
+- Streams, by contrast, cannot survive through `exec' functions,
+-because they are located in the memory of the process itself. The new
+-process image has no streams except those it creates afresh. Each of
+-the streams in the pre-`exec' process image has a descriptor inside it,
+-and these descriptors do survive through `exec' (provided that they do
+-not have `FD_CLOEXEC' set). The new process image can reconnect these
+-to new streams using `fdopen' (*note Descriptors and Streams::).

+-
+-Process Completion
+-==================
+-
+- The functions described in this section are used to wait for a child
+-process to terminate or stop, and determine its status. These functions
+-are declared in the header file `sys/wait.h'.
+-
+- - Function: pid_t waitpid (pid_t PID, int *STATUS-PTR, int OPTIONS)
+- The `waitpid' function is used to request status information from a
+- child process whose process ID is PID. Normally, the calling
+- process is suspended until the child process makes status
+- information available by terminating.
+-
+- Other values for the PID argument have special interpretations. A
+- value of `-1' or `WAIT_ANY' requests status information for any
+- child process; a value of `0' or `WAIT_MYPGRP' requests
+- information for any child process in the same process group as the
+- calling process; and any other negative value - PGID requests
+- information for any child process whose process group ID is PGID.
+-
+- If status information for a child process is available
+- immediately, this function returns immediately without waiting.
+- If more than one eligible child process has status information
+- available, one of them is chosen randomly, and its status is
+- returned immediately. To get the status from the other eligible
+- child processes, you need to call `waitpid' again.
+-
+- The OPTIONS argument is a bit mask. Its value should be the
+- bitwise OR (that is, the `|' operator) of zero or more of the
+- `WNOHANG' and `WUNTRACED' flags. You can use the `WNOHANG' flag
+- to indicate that the parent process shouldn't wait; and the
+- `WUNTRACED' flag to request status information from stopped
+- processes as well as processes that have terminated.
+-
+- The status information from the child process is stored in the
+- object that STATUS-PTR points to, unless STATUS-PTR is a null
+- pointer.
+-
+- This function is a cancellation point in multi-threaded programs.
+- This is a problem if the thread allocates some resources (like
+- memory, file descriptors, semaphores or whatever) at the time
+- `waitpid' is called. If the thread gets canceled these resources
+- stay allocated until the program ends. To avoid this calls to
+- `waitpid' should be protected using cancellation handlers.
+-
+- The return value is normally the process ID of the child process
+- whose status is reported. If there are child processes but none
+- of them is waiting to be noticed, `waitpid' will block until one
+- is. However, if the `WNOHANG' option was specified, `waitpid'
+- will return zero instead of blocking.
+-
+- If a specific PID to wait for was given to `waitpid', it will
+- ignore all other children (if any). Therefore if there are
+- children waiting to be noticed but the child whose PID was
+- specified is not one of them, `waitpid' will block or return zero
+- as described above.
+-
+- A value of `-1' is returned in case of error. The following
+- `errno' error conditions are defined for this function:
+-
+- `EINTR'
+- The function was interrupted by delivery of a signal to the
+- calling process. *Note Interrupted Primitives::.
+-
+- `ECHILD'
+- There are no child processes to wait for, or the specified PID
+- is not a child of the calling process.
+-
+- `EINVAL'
+- An invalid value was provided for the OPTIONS argument.
+-
+- These symbolic constants are defined as values for the PID argument
+-to the `waitpid' function.
+-
+-`WAIT_ANY'
+- This constant macro (whose value is `-1') specifies that `waitpid'
+- should return status information about any child process.
+-
+-`WAIT_MYPGRP'
+- This constant (with value `0') specifies that `waitpid' should
+- return status information about any child process in the same
+- process group as the calling process.
+-
+- These symbolic constants are defined as flags for the OPTIONS
+-argument to the `waitpid' function. You can bitwise-OR the flags
+-together to obtain a value to use as the argument.
+-
+-`WNOHANG'
+- This flag specifies that `waitpid' should return immediately
+- instead of waiting, if there is no child process ready to be
+- noticed.
+-
+-`WUNTRACED'
+- This flag specifies that `waitpid' should report the status of any
+- child processes that have been stopped as well as those that have
+- terminated.
+-
+- - Function: pid_t wait (int *STATUS-PTR)
+- This is a simplified version of `waitpid', and is used to wait
+- until any one child process terminates. The call:
+-
+- wait (&status)
+-
+- is exactly equivalent to:
+-
+- waitpid (-1, &status, 0)
+-
+- This function is a cancellation point in multi-threaded programs.
+- This is a problem if the thread allocates some resources (like
+- memory, file descriptors, semaphores or whatever) at the time
+- `wait' is called. If the thread gets canceled these resources
+- stay allocated until the program ends. To avoid this calls to
+- `wait' should be protected using cancellation handlers.
+-
+- - Function: pid_t wait4 (pid_t PID, int *STATUS-PTR, int OPTIONS,
+- struct rusage *USAGE)
+- If USAGE is a null pointer, `wait4' is equivalent to `waitpid
+- (PID, STATUS-PTR, OPTIONS)'.
+-
+- If USAGE is not null, `wait4' stores usage figures for the child
+- process in `*RUSAGE' (but only if the child has terminated, not if
+- it has stopped). *Note Resource Usage::.
+-
+- This function is a BSD extension.
+-
+- Here's an example of how to use `waitpid' to get the status from all
+-child processes that have terminated, without ever waiting. This
+-function is designed to be a handler for `SIGCHLD', the signal that
+-indicates that at least one child process has terminated.

+-Process Completion Status
+-=========================
+-
+- If the exit status value (*note Program Termination::) of the child
+-process is zero, then the status value reported by `waitpid' or `wait'
+-is also zero. You can test for other kinds of information encoded in
+-the returned status value using the following macros. These macros are
+-defined in the header file `sys/wait.h'.
+-
+- - Macro: int WIFEXITED (int STATUS)
+- This macro returns a nonzero value if the child process terminated
+- normally with `exit' or `_exit'.
+-
+- - Macro: int WEXITSTATUS (int STATUS)
+- If `WIFEXITED' is true of STATUS, this macro returns the low-order
+- 8 bits of the exit status value from the child process. *Note
+- Exit Status::.
+-
+- - Macro: int WIFSIGNALED (int STATUS)
+- This macro returns a nonzero value if the child process terminated
+- because it received a signal that was not handled. *Note Signal
+- Handling::.
+-
+- - Macro: int WTERMSIG (int STATUS)
+- If `WIFSIGNALED' is true of STATUS, this macro returns the signal
+- number of the signal that terminated the child process.
+-
+- - Macro: int WCOREDUMP (int STATUS)
+- This macro returns a nonzero value if the child process terminated
+- and produced a core dump.
+-
+- - Macro: int WIFSTOPPED (int STATUS)
+- This macro returns a nonzero value if the child process is stopped.
+-
+- - Macro: int WSTOPSIG (int STATUS)
+- If `WIFSTOPPED' is true of STATUS, this macro returns the signal
+- number of the signal that caused the child process to stop.

+-BSD Process Wait Functions
+-==========================
+-
+- The GNU library also provides these related facilities for
+-compatibility with BSD Unix. BSD uses the `union wait' data type to
+-represent status values rather than an `int'. The two representations
+-are actually interchangeable; they describe the same bit patterns. The
+-GNU C Library defines macros such as `WEXITSTATUS' so that they will
+-work on either kind of object, and the `wait' function is defined to
+-accept either type of pointer as its STATUS-PTR argument.
+-
+- These functions are declared in `sys/wait.h'.
+-
+- - Data Type: union wait
+- This data type represents program termination status values. It
+- has the following members:
+-
+- `int w_termsig'
+- The value of this member is the same as that of the
+- `WTERMSIG' macro.
+-
+- `int w_coredump'
+- The value of this member is the same as that of the
+- `WCOREDUMP' macro.
+-
+- `int w_retcode'
+- The value of this member is the same as that of the
+- `WEXITSTATUS' macro.
+-
+- `int w_stopsig'
+- The value of this member is the same as that of the
+- `WSTOPSIG' macro.
+-
+- Instead of accessing these members directly, you should use the
+- equivalent macros.
+-
+- The `wait3' function is the predecessor to `wait4', which is more
+-flexible. `wait3' is now obsolete.
+-
+- - Function: pid_t wait3 (union wait *STATUS-PTR, int OPTIONS, struct
+- rusage *USAGE)
+- If USAGE is a null pointer, `wait3' is equivalent to `waitpid (-1,
+- STATUS-PTR, OPTIONS)'.
+-
+- If USAGE is not null, `wait3' stores usage figures for the child
+- process in `*RUSAGE' (but only if the child has terminated, not if
+- it has stopped). *Note Resource Usage::.

+-Process Creation Example
+-========================
+-
+- Here is an example program showing how you might write a function
+-similar to the built-in `system'. It executes its COMMAND argument
+-using the equivalent of `sh -c COMMAND'.
+-
+- #include <stddef.h>
+- #include <stdlib.h>
+- #include <unistd.h>
+- #include <sys/types.h>
+- #include <sys/wait.h>
+-
+- /* Execute the command using this shell program. */
+- #define SHELL "/bin/sh"
+-
+- int
+- my_system (const char *command)
+- {
+- int status;
+- pid_t pid;
+-
+- pid = fork ();
+- if (pid == 0)
+- {
+- /* This is the child process. Execute the shell command. */
+- execl (SHELL, SHELL, "-c", command, NULL);
+- _exit (EXIT_FAILURE);
+- }
+- else if (pid < 0)
+- /* The fork failed. Report failure. */
+- status = -1;
+- else
+- /* This is the parent process. Wait for the child to complete. */
+- if (waitpid (pid, &status, 0) != pid)
+- status = -1;
+- return status;
+- }
+-
+- There are a couple of things you should pay attention to in this
+-example.
+-
+- Remember that the first `argv' argument supplied to the program
+-represents the name of the program being executed. That is why, in the
+-call to `execl', `SHELL' is supplied once to name the program to
+-execute and a second time to supply a value for `argv[0]'.
+-
+- The `execl' call in the child process doesn't return if it is
+-successful. If it fails, you must do something to make the child
+-process terminate. Just returning a bad status code with `return'
+-would leave two processes running the original program. Instead, the
+-right behavior is for the child process to report failure to its parent
+-process.
+-
+- Call `_exit' to accomplish this. The reason for using `_exit'
+-instead of `exit' is to avoid flushing fully buffered streams such as
+-`stdout'. The buffers of these streams probably contain data that was
+-copied from the parent process by the `fork', data that will be output
+-eventually by the parent process. Calling `exit' in the child would
+-output the data twice. *Note Termination Internals::.

+-Job Control
+-***********
+-
+- "Job control" refers to the protocol for allowing a user to move
+-between multiple "process groups" (or "jobs") within a single "login
+-session". The job control facilities are set up so that appropriate
+-behavior for most programs happens automatically and they need not do
+-anything special about job control. So you can probably ignore the
+-material in this chapter unless you are writing a shell or login
+-program.
+-
+- You need to be familiar with concepts relating to process creation
+-(*note Process Creation Concepts::) and signal handling (*note Signal
+-Handling::) in order to understand this material presented in this
+-chapter.

+-
+-Concepts of Job Control
+-=======================
+-
+- The fundamental purpose of an interactive shell is to read commands
+-from the user's terminal and create processes to execute the programs
+-specified by those commands. It can do this using the `fork' (*note
+-Creating a Process::) and `exec' (*note Executing a File::) functions.
+-
+- A single command may run just one process--but often one command uses
+-several processes. If you use the `|' operator in a shell command, you
+-explicitly request several programs in their own processes. But even
+-if you run just one program, it can use multiple processes internally.
+-For example, a single compilation command such as `cc -c foo.c'
+-typically uses four processes (though normally only two at any given
+-time). If you run `make', its job is to run other programs in separate
+-processes.
+-
+- The processes belonging to a single command are called a "process
+-group" or "job". This is so that you can operate on all of them at
+-once. For example, typing `C-c' sends the signal `SIGINT' to terminate
+-all the processes in the foreground process group.
+-
+- A "session" is a larger group of processes. Normally all the
+-processes that stem from a single login belong to the same session.
+-
+- Every process belongs to a process group. When a process is
+-created, it becomes a member of the same process group and session as
+-its parent process. You can put it in another process group using the
+-`setpgid' function, provided the process group belongs to the same
+-session.
+-
+- The only way to put a process in a different session is to make it
+-the initial process of a new session, or a "session leader", using the
+-`setsid' function. This also puts the session leader into a new
+-process group, and you can't move it out of that process group again.
+-
+- Usually, new sessions are created by the system login program, and
+-the session leader is the process running the user's login shell.
+-
+- A shell that supports job control must arrange to control which job
+-can use the terminal at any time. Otherwise there might be multiple
+-jobs trying to read from the terminal at once, and confusion about which
+-process should receive the input typed by the user. To prevent this,
+-the shell must cooperate with the terminal driver using the protocol
+-described in this chapter.
+-
+- The shell can give unlimited access to the controlling terminal to
+-only one process group at a time. This is called the "foreground job"
+-on that controlling terminal. Other process groups managed by the shell
+-that are executing without such access to the terminal are called
+-"background jobs".
+-
+- If a background job needs to read from its controlling terminal, it
+-is "stopped" by the terminal driver; if the `TOSTOP' mode is set,
+-likewise for writing. The user can stop a foreground job by typing the
+-SUSP character (*note Special Characters::) and a program can stop any
+-job by sending it a `SIGSTOP' signal. It's the responsibility of the
+-shell to notice when jobs stop, to notify the user about them, and to
+-provide mechanisms for allowing the user to interactively continue
+-stopped jobs and switch jobs between foreground and background.

+-
+-Job Control is Optional
+-=======================
+-
+- Not all operating systems support job control. The GNU system does
+-support job control, but if you are using the GNU library on some other
+-system, that system may not support job control itself.
+-
+- You can use the `_POSIX_JOB_CONTROL' macro to test at compile-time
+-whether the system supports job control. *Note System Options::.
+-
+- If job control is not supported, then there can be only one process
+-group per session, which behaves as if it were always in the foreground.
+-The functions for creating additional process groups simply fail with
+-the error code `ENOSYS'.
+-
+- The macros naming the various job control signals (*note Job Control
+-Signals::) are defined even if job control is not supported. However,
+-the system never generates these signals, and attempts to send a job
+-control signal or examine or specify their actions report errors or do
+-nothing.

+-
+-Controlling Terminal of a Process
+-=================================
+-
+- One of the attributes of a process is its controlling terminal.
+-Child processes created with `fork' inherit the controlling terminal
+-from their parent process. In this way, all the processes in a session
+-inherit the controlling terminal from the session leader. A session
+-leader that has control of a terminal is called the "controlling
+-process" of that terminal.
+-
+- You generally do not need to worry about the exact mechanism used to
+-allocate a controlling terminal to a session, since it is done for you
+-by the system when you log in.
+-
+- An individual process disconnects from its controlling terminal when
+-it calls `setsid' to become the leader of a new session. *Note Process
+-Group Functions::.
+-
+-\1f
+-File: libc.info, Node: Access to the Terminal, Next: Orphaned Process Groups, Prev: Controlling Terminal, Up: Job Control
+-
+-Access to the Controlling Terminal
+-==================================
+-
+- Processes in the foreground job of a controlling terminal have
+-unrestricted access to that terminal; background processes do not. This
+-section describes in more detail what happens when a process in a
+-background job tries to access its controlling terminal.
+-
+- When a process in a background job tries to read from its controlling
+-terminal, the process group is usually sent a `SIGTTIN' signal. This
+-normally causes all of the processes in that group to stop (unless they
+-handle the signal and don't stop themselves). However, if the reading
+-process is ignoring or blocking this signal, then `read' fails with an
+-`EIO' error instead.
+-
+- Similarly, when a process in a background job tries to write to its
+-controlling terminal, the default behavior is to send a `SIGTTOU'
+-signal to the process group. However, the behavior is modified by the
+-`TOSTOP' bit of the local modes flags (*note Local Modes::). If this
+-bit is not set (which is the default), then writing to the controlling
+-terminal is always permitted without sending a signal. Writing is also
+-permitted if the `SIGTTOU' signal is being ignored or blocked by the
+-writing process.
+-
+- Most other terminal operations that a program can do are treated as
+-reading or as writing. (The description of each operation should say
+-which.)
+-
+- For more information about the primitive `read' and `write'
+-functions, see *Note I/O Primitives::.

+-File: libc.info, Node: Orphaned Process Groups, Next: Implementing a Shell, Prev: Access to the Terminal, Up: Job Control
+-
+-Orphaned Process Groups
+-=======================
+-
+- When a controlling process terminates, its terminal becomes free and
+-a new session can be established on it. (In fact, another user could
+-log in on the terminal.) This could cause a problem if any processes
+-from the old session are still trying to use that terminal.
+-
+- To prevent problems, process groups that continue running even after
+-the session leader has terminated are marked as "orphaned process
+-groups".
+-
+- When a process group becomes an orphan, its processes are sent a
+-`SIGHUP' signal. Ordinarily, this causes the processes to terminate.
+-However, if a program ignores this signal or establishes a handler for
+-it (*note Signal Handling::), it can continue running as in the orphan
+-process group even after its controlling process terminates; but it
+-still cannot access the terminal any more.

+-Data Structures for the Shell
+------------------------------
+-
+- All of the program examples included in this chapter are part of a
+-simple shell program. This section presents data structures and
+-utility functions which are used throughout the example.
+-
+- The sample shell deals mainly with two data structures. The `job'
+-type contains information about a job, which is a set of subprocesses
+-linked together with pipes. The `process' type holds information about
+-a single subprocess. Here are the relevant data structure declarations:
+-
+- /* A process is a single process. */
+- typedef struct process
+- {
+- struct process *next; /* next process in pipeline */
+- char **argv; /* for exec */
+- pid_t pid; /* process ID */
+- char completed; /* true if process has completed */
+- char stopped; /* true if process has stopped */
+- int status; /* reported status value */
+- } process;
+-
+- /* A job is a pipeline of processes. */
+- typedef struct job
+- {
+- struct job *next; /* next active job */
+- char *command; /* command line, used for messages */
+- process *first_process; /* list of processes in this job */
+- pid_t pgid; /* process group ID */
+- char notified; /* true if user told about stopped job */
+- struct termios tmodes; /* saved terminal modes */
+- int stdin, stdout, stderr; /* standard i/o channels */
+- } job;
+-
+- /* The active jobs are linked into a list. This is its head. */
+- job *first_job = NULL;
+-
+- Here are some utility functions that are used for operating on `job'
+-objects.
+-
+- /* Find the active job with the indicated PGID. */
+- job *
+- find_job (pid_t pgid)
+- {
+- job *j;
+-
+- for (j = first_job; j; j = j->next)
+- if (j->pgid == pgid)
+- return j;
+- return NULL;
+- }
+-
+- /* Return true if all processes in the job have stopped or completed. */
+- int
+- job_is_stopped (job *j)
+- {
+- process *p;
+-
+- for (p = j->first_process; p; p = p->next)
+- if (!p->completed && !p->stopped)
+- return 0;
+- return 1;
+- }
+-
+- /* Return true if all processes in the job have completed. */
+- int

+-
+-Initializing the Shell
+-----------------------
+-
+- When a shell program that normally performs job control is started,
+-it has to be careful in case it has been invoked from another shell
+-that is already doing its own job control.
+-
+- A subshell that runs interactively has to ensure that it has been
+-placed in the foreground by its parent shell before it can enable job
+-control itself. It does this by getting its initial process group ID
+-with the `getpgrp' function, and comparing it to the process group ID
+-of the current foreground job associated with its controlling terminal
+-(which can be retrieved using the `tcgetpgrp' function).
+-
+- If the subshell is not running as a foreground job, it must stop
+-itself by sending a `SIGTTIN' signal to its own process group. It may
+-not arbitrarily put itself into the foreground; it must wait for the
+-user to tell the parent shell to do this. If the subshell is continued
+-again, it should repeat the check and stop itself again if it is still
+-not in the foreground.
+-
+- Once the subshell has been placed into the foreground by its parent
+-shell, it can enable its own job control. It does this by calling
+-`setpgid' to put itself into its own process group, and then calling
+-`tcsetpgrp' to place this process group into the foreground.
+-
+- When a shell enables job control, it should set itself to ignore all
+-the job control stop signals so that it doesn't accidentally stop
+-itself. You can do this by setting the action for all the stop signals
+-to `SIG_IGN'.
+-
+- A subshell that runs non-interactively cannot and should not support
+-job control. It must leave all processes it creates in the same process
+-group as the shell itself; this allows the non-interactive shell and its
+-child processes to be treated as a single job by the parent shell. This
+-is easy to do--just don't use any of the job control primitives--but
+-you must remember to make the shell do it.
+-
+- Here is the initialization code for the sample shell that shows how
+-to do all of this.
+-
+- /* Keep track of attributes of the shell. */
+-
+- #include <sys/types.h>
+- #include <termios.h>
+- #include <unistd.h>
+-
+- pid_t shell_pgid;
+- struct termios shell_tmodes;
+- int shell_terminal;

+- /* See if we are running interactively. */
+- shell_terminal = STDIN_FILENO;
+- shell_is_interactive = isatty (shell_terminal);

+- {
+- /* Loop until we are in the foreground. */

+-
+-Launching Jobs
+---------------
+-
+- Once the shell has taken responsibility for performing job control on
+-its controlling terminal, it can launch jobs in response to commands
+-typed by the user.
+-
+- To create the processes in a process group, you use the same `fork'
+-and `exec' functions described in *Note Process Creation Concepts::.
+-Since there are multiple child processes involved, though, things are a
+-little more complicated and you must be careful to do things in the
+-right order. Otherwise, nasty race conditions can result.
+-
+- You have two choices for how to structure the tree of parent-child
+-relationships among the processes. You can either make all the
+-processes in the process group be children of the shell process, or you
+-can make one process in group be the ancestor of all the other processes
+-in that group. The sample shell program presented in this chapter uses
+-the first approach because it makes bookkeeping somewhat simpler.
+-
+- As each process is forked, it should put itself in the new process
+-group by calling `setpgid'; see *Note Process Group Functions::. The
+-first process in the new group becomes its "process group leader", and
+-its process ID becomes the "process group ID" for the group.
+-
+- The shell should also call `setpgid' to put each of its child
+-processes into the new process group. This is because there is a
+-potential timing problem: each child process must be put in the process
+-group before it begins executing a new program, and the shell depends on
+-having all the child processes in the group before it continues
+-executing. If both the child processes and the shell call `setpgid',
+-this ensures that the right things happen no matter which process gets
+-to it first.
+-
+- If the job is being launched as a foreground job, the new process
+-group also needs to be put into the foreground on the controlling
+-terminal using `tcsetpgrp'. Again, this should be done by the shell as
+-well as by each of its child processes, to avoid race conditions.
+-
+- The next thing each child process should do is to reset its signal
+-actions.
+-
+- During initialization, the shell process set itself to ignore job
+-control signals; see *Note Initializing the Shell::. As a result, any
+-child processes it creates also ignore these signals by inheritance.
+-This is definitely undesirable, so each child process should explicitly
+-set the actions for these signals back to `SIG_DFL' just after it is
+-forked.
+-
+- Since shells follow this convention, applications can assume that
+-they inherit the correct handling of these signals from the parent
+-process. But every application has a responsibility not to mess up the
+-handling of stop signals. Applications that disable the normal
+-interpretation of the SUSP character should provide some other
+-mechanism for the user to stop the job. When the user invokes this
+-mechanism, the program should send a `SIGTSTP' signal to the process
+-group of the process, not just to the process itself. *Note Signaling
+-Another Process::.
+-
+- Finally, each child process should call `exec' in the normal way.
+-This is also the point at which redirection of the standard input and
+-output channels should be handled. *Note Duplicating Descriptors::,
+-for an explanation of how to do this.
+-
+- Here is the function from the sample shell program that is
+-responsible for launching a program. The function is executed by each
+-child process immediately after it has been forked by the shell, and
+-never returns.

+-
+-Foreground and Background
+--------------------------
+-
+- Now let's consider what actions must be taken by the shell when it
+-launches a job into the foreground, and how this differs from what must
+-be done when a background job is launched.
+-
+- When a foreground job is launched, the shell must first give it
+-access to the controlling terminal by calling `tcsetpgrp'. Then, the
+-shell should wait for processes in that process group to terminate or
+-stop. This is discussed in more detail in *Note Stopped and Terminated
+-Jobs::.
+-
+- When all of the processes in the group have either completed or
+-stopped, the shell should regain control of the terminal for its own
+-process group by calling `tcsetpgrp' again. Since stop signals caused
+-by I/O from a background process or a SUSP character typed by the user
+-are sent to the process group, normally all the processes in the job
+-stop together.
+-
+- The foreground job may have left the terminal in a strange state, so
+-the shell should restore its own saved terminal modes before
+-continuing. In case the job is merely stopped, the shell should first
+-save the current terminal modes so that it can restore them later if
+-the job is continued. The functions for dealing with terminal modes are
+-`tcgetattr' and `tcsetattr'; these are described in *Note Terminal
+-Modes::.
+-
+- Here is the sample shell's function for doing all of this.
+-
+- /* Put job J in the foreground. If CONT is nonzero,
+- restore the saved terminal modes and send the process group a
+- `SIGCONT' signal to wake it up before we block. */
+-
+- void
+- put_job_in_foreground (job *j, int cont)
+- {
+- /* Put the job into the foreground. */
+- tcsetpgrp (shell_terminal, j->pgid);
+-
+- /* Send the job a continue signal, if necessary. */
+- if (cont)
+- {
+- tcsetattr (shell_terminal, TCSADRAIN, &j->tmodes);
+- if (kill (- j->pgid, SIGCONT) < 0)
+- perror ("kill (SIGCONT)");
+- }
+-
+- /* Wait for it to report. */
+- wait_for_job (j);
+-
+- /* Put the shell back in the foreground. */
+- tcsetpgrp (shell_terminal, shell_pgid);
+-
+- /* Restore the shell's terminal modes. */
+- tcgetattr (shell_terminal, &j->tmodes);
+- tcsetattr (shell_terminal, TCSADRAIN, &shell_tmodes);
+- }
+-
+- If the process group is launched as a background job, the shell
+-should remain in the foreground itself and continue to read commands
+-from the terminal.
+-
+- In the sample shell, there is not much that needs to be done to put
+-a job into the background. Here is the function it uses:
+-
+- /* Put a job in the background. If the cont argument is true, send
+- the process group a `SIGCONT' signal to wake it up. */
+-
+- void
+- put_job_in_background (job *j, int cont)
+- {
+- /* Send the job a continue signal, if necessary. */
+- if (cont)
+- if (kill (-j->pgid, SIGCONT) < 0)
+- perror ("kill (SIGCONT)");
+- }

+-
+-Stopped and Terminated Jobs
+----------------------------
+-
+- When a foreground process is launched, the shell must block until
+-all of the processes in that job have either terminated or stopped. It
+-can do this by calling the `waitpid' function; see *Note Process
+-Completion::. Use the `WUNTRACED' option so that status is reported
+-for processes that stop as well as processes that terminate.
+-
+- The shell must also check on the status of background jobs so that it
+-can report terminated and stopped jobs to the user; this can be done by
+-calling `waitpid' with the `WNOHANG' option. A good place to put a
+-such a check for terminated and stopped jobs is just before prompting
+-for a new command.
+-
+- The shell can also receive asynchronous notification that there is
+-status information available for a child process by establishing a
+-handler for `SIGCHLD' signals. *Note Signal Handling::.
+-
+- In the sample shell program, the `SIGCHLD' signal is normally
+-ignored. This is to avoid reentrancy problems involving the global data
+-structures the shell manipulates. But at specific times when the shell
+-is not using these data structures--such as when it is waiting for
+-input on the terminal--it makes sense to enable a handler for
+-`SIGCHLD'. The same function that is used to do the synchronous status
+-checks (`do_job_notification', in this case) can also be called from
+-within this handler.
+-
+- Here are the parts of the sample shell program that deal with

+-Continuing Stopped Jobs
+------------------------
+-
+- The shell can continue a stopped job by sending a `SIGCONT' signal
+-to its process group. If the job is being continued in the foreground,
+-the shell should first invoke `tcsetpgrp' to give the job access to the
+-terminal, and restore the saved terminal settings. After continuing a
+-job in the foreground, the shell should wait for the job to stop or
+-complete, as if the job had just been launched in the foreground.
+-
+- The sample shell program handles both newly created and continued
+-jobs with the same pair of functions, `put_job_in_foreground' and
+-`put_job_in_background'. The definitions of these functions were given
+-in *Note Foreground and Background::. When continuing a stopped job, a
+-nonzero value is passed as the CONT argument to ensure that the
+-`SIGCONT' signal is sent and the terminal modes reset, as appropriate.
+-
+- This leaves only a function for updating the shell's internal
+-bookkeeping about the job being continued:
+-
+- /* Mark a stopped job J as being running again. */
+-
+- void
+- mark_job_as_running (job *j)
+- {

+-The Missing Pieces
+-------------------
+-
+- The code extracts for the sample shell included in this chapter are
+-only a part of the entire shell program. In particular, nothing at all
+-has been said about how `job' and `program' data structures are
+-allocated and initialized.
+-
+- Most real shells provide a complex user interface that has support
+-for a command language; variables; abbreviations, substitutions, and
+-pattern matching on file names; and the like. All of this is far too
+-complicated to explain here! Instead, we have concentrated on showing
+-how to implement the core process creation and job control functions
+-that can be called from such a shell.
+-
+- Here is a table summarizing the major entry points we have presented:
+-
+-`void init_shell (void)'
+- Initialize the shell's internal state. *Note Initializing the
+- Shell::.
+-
+-`void launch_job (job *J, int FOREGROUND)'
+- Launch the job J as either a foreground or background job. *Note
+- Launching Jobs::.
+-
+-`void do_job_notification (void)'
+- Check for and report any jobs that have terminated or stopped.
+- Can be called synchronously or within a handler for `SIGCHLD'
+- signals. *Note Stopped and Terminated Jobs::.
+-
+-`void continue_job (job *J, int FOREGROUND)'
+- Continue the job J. *Note Continuing Stopped Jobs::.
+-
+- Of course, a real shell would also want to provide other functions
+-for managing jobs. For example, it would be useful to have commands to
+-list all active jobs or to send a signal (such as `SIGKILL') to a job.

+-
+-Identifying the Controlling Terminal
+-------------------------------------
+-
+- You can use the `ctermid' function to get a file name that you can
+-use to open the controlling terminal. In the GNU library, it returns
+-the same string all the time: `"/dev/tty"'. That is a special "magic"
+-file name that refers to the controlling terminal of the current
+-process (if it has one). To find the name of the specific terminal
+-device, use `ttyname'; *note Is It a Terminal::.
+-
+- The function `ctermid' is declared in the header file `stdio.h'.
+-
+- - Function: char * ctermid (char *STRING)
+- The `ctermid' function returns a string containing the file name of
+- the controlling terminal for the current process. If STRING is
+- not a null pointer, it should be an array that can hold at least
+- `L_ctermid' characters; the string is returned in this array.
+- Otherwise, a pointer to a string in a static area is returned,
+- which might get overwritten on subsequent calls to this function.
+-
+- An empty string is returned if the file name cannot be determined
+- for any reason. Even if a file name is returned, access to the
+- file it represents is not guaranteed.
+-
+- - Macro: int L_ctermid
+- The value of this macro is an integer constant expression that
+- represents the size of a string large enough to hold the file name
+- returned by `ctermid'.
+-
+- See also the `isatty' and `ttyname' functions, in *Note Is It a
+-Terminal::.

+-File: libc.info, Node: Process Group Functions, Next: Terminal Access Functions, Prev: Identifying the Terminal, Up: Functions for Job Control
+-
+-Process Group Functions
+------------------------
+-
+- Here are descriptions of the functions for manipulating process
+-groups. Your program should include the header files `sys/types.h' and
+-`unistd.h' to use these functions.
+-
+- - Function: pid_t setsid (void)
+- The `setsid' function creates a new session. The calling process
+- becomes the session leader, and is put in a new process group whose
+- process group ID is the same as the process ID of that process.
+- There are initially no other processes in the new process group,
+- and no other process groups in the new session.
+-
+- This function also makes the calling process have no controlling
+- terminal.
+-
+- The `setsid' function returns the new process group ID of the
+- calling process if successful. A return value of `-1' indicates an
+- error. The following `errno' error conditions are defined for this
+- function:
+-
+- `EPERM'
+- The calling process is already a process group leader, or
+- there is already another process group around that has the
+- same process group ID.
+-
+- - Function: pid_t getsid (pid_t PID)
+- The `getsid' function returns the process group ID of the session
+- leader of the specified process. If a PID is `0', the process
+- group ID of the session leader of the current process is returned.
+-
+- In case of error `-1' is returned and `errno' is set. The
+- following `errno' error conditions are defined for this function:
+-
+- `ESRCH'
+- There is no process with the given process ID PID.
+-
+- `EPERM'
+- The calling process and the process specified by PID are in
+- different sessions, and the implementation doesn't allow to
+- access the process group ID of the session leader of the
+- process with ID PID from the calling process.
+-
+- The `getpgrp' function has two definitions: one derived from BSD
+-Unix, and one from the POSIX.1 standard. The feature test macros you
+-have selected (*note Feature Test Macros::) determine which definition
+-you get. Specifically, you get the BSD version if you define
+-`_BSD_SOURCE'; otherwise, you get the POSIX version if you define
+-`_POSIX_SOURCE' or `_GNU_SOURCE'. Programs written for old BSD systems
+-will not include `unistd.h', which defines `getpgrp' specially under
+-`_BSD_SOURCE'. You must link such programs with the `-lbsd-compat'
+-option to get the BSD definition.
+-
+- - POSIX.1 Function: pid_t getpgrp (void)
+- The POSIX.1 definition of `getpgrp' returns the process group ID of
+- the calling process.
+-
+- - BSD Function: pid_t getpgrp (pid_t PID)
+- The BSD definition of `getpgrp' returns the process group ID of the
+- process PID. You can supply a value of `0' for the PID argument
+- to get information about the calling process.
+-
+- - System V Function: int getpgid (pid_t PID)
+- `getpgid' is the same as the BSD function `getpgrp'. It returns
+- the process group ID of the process PID. You can supply a value
+- of `0' for the PID argument to get information about the calling
+- process.
+-
+- In case of error `-1' is returned and `errno' is set. The
+- following `errno' error conditions are defined for this function:
+-
+- `ESRCH'
+- There is no process with the given process ID PID. The
+- calling process and the process specified by PID are in
+- different sessions, and the implementation doesn't allow to
+- access the process group ID of the process with ID PID from
+- the calling process.
+-
+- - Function: int setpgid (pid_t PID, pid_t PGID)
+- The `setpgid' function puts the process PID into the process group
+- PGID. As a special case, either PID or PGID can be zero to
+- indicate the process ID of the calling process.
+-
+- This function fails on a system that does not support job control.
+- *Note Job Control is Optional::, for more information.
+-
+- If the operation is successful, `setpgid' returns zero. Otherwise
+- it returns `-1'. The following `errno' error conditions are
+- defined for this function:
+-
+- `EACCES'
+- The child process named by PID has executed an `exec'
+- function since it was forked.
+-
+- `EINVAL'
+- The value of the PGID is not valid.
+-
+- `ENOSYS'
+- The system doesn't support job control.
+-
+- `EPERM'
+- The process indicated by the PID argument is a session leader,
+- or is not in the same session as the calling process, or the
+- value of the PGID argument doesn't match a process group ID
+- in the same session as the calling process.
+-
+- `ESRCH'
+- The process indicated by the PID argument is not the calling
+- process or a child of the calling process.
+-
+- - Function: int setpgrp (pid_t PID, pid_t PGID)
+- This is the BSD Unix name for `setpgid'. Both functions do exactly
+- the same thing.
+-
+-\1f
+-File: libc.info, Node: Terminal Access Functions, Prev: Process Group Functions, Up: Functions for Job Control
+-
+-Functions for Controlling Terminal Access
+------------------------------------------
+-
+- These are the functions for reading or setting the foreground
+-process group of a terminal. You should include the header files
+-`sys/types.h' and `unistd.h' in your application to use these functions.
+-
+- Although these functions take a file descriptor argument to specify
+-the terminal device, the foreground job is associated with the terminal
+-file itself and not a particular open file descriptor.
+-
+- - Function: pid_t tcgetpgrp (int FILEDES)
+- This function returns the process group ID of the foreground
+- process group associated with the terminal open on descriptor
+- FILEDES.
+-
+- If there is no foreground process group, the return value is a
+- number greater than `1' that does not match the process group ID
+- of any existing process group. This can happen if all of the
+- processes in the job that was formerly the foreground job have
+- terminated, and no other job has yet been moved into the
+- foreground.
+-
+- In case of an error, a value of `-1' is returned. The following
+- `errno' error conditions are defined for this function:
+-
+- `EBADF'
+- The FILEDES argument is not a valid file descriptor.
+-
+- `ENOSYS'
+- The system doesn't support job control.
+-
+- `ENOTTY'
+- The terminal file associated with the FILEDES argument isn't
+- the controlling terminal of the calling process.
+-
+- - Function: int tcsetpgrp (int FILEDES, pid_t PGID)
+- This function is used to set a terminal's foreground process group
+- ID. The argument FILEDES is a descriptor which specifies the
+- terminal; PGID specifies the process group. The calling process
+- must be a member of the same session as PGID and must have the same
+- controlling terminal.
+-
+- For terminal access purposes, this function is treated as output.
+- If it is called from a background process on its controlling
+- terminal, normally all processes in the process group are sent a
+- `SIGTTOU' signal. The exception is if the calling process itself
+- is ignoring or blocking `SIGTTOU' signals, in which case the
+- operation is performed and no signal is sent.
+-
+- If successful, `tcsetpgrp' returns `0'. A return value of `-1'
+- indicates an error. The following `errno' error conditions are
+- defined for this function:
+-
+- `EBADF'
+- The FILEDES argument is not a valid file descriptor.
+-
+- `EINVAL'
+- The PGID argument is not valid.
+-
+- `ENOSYS'
+- The system doesn't support job control.
+-
+- `ENOTTY'
+- The FILEDES isn't the controlling terminal of the calling
+- process.
+-
+- `EPERM'
+- The PGID isn't a process group in the same session as the
+- calling process.
+-
+- - Function: pid_t tcgetsid (int FILDES)
+- This function is used to obtain the process group ID of the session
+- for which the terminal specified by FILDES is the controlling
+- terminal. If the call is successful the group ID is returned.
+- Otherwise the return value is `(pid_t) -1' and the global variable
+- ERRNO is set to the following value:
+- `EBADF'
+- The FILEDES argument is not a valid file descriptor.
+-
+- `ENOTTY'
+- The calling process does not have a controlling terminal, or
+- the file is not the controlling terminal.

+-System Databases and Name Service Switch
+-****************************************
+-
+- Various functions in the C Library need to be configured to work
+-correctly in the local environment. Traditionally, this was done by
+-using files (e.g., `/etc/passwd'), but other nameservices (like the
+-Network Information Service (NIS) and the Domain Name Service (DNS))
+-became popular, and were hacked into the C library, usually with a fixed
+-search order (*note frobnicate: (jargon)frobnicate.).
+-
+- The GNU C Library contains a cleaner solution of this problem. It is
+-designed after a method used by Sun Microsystems in the C library of
+-Solaris 2. GNU C Library follows their name and calls this scheme
+-"Name Service Switch" (NSS).
+-
+- Though the interface might be similar to Sun's version there is no
+-common code. We never saw any source code of Sun's implementation and
+-so the internal interface is incompatible. This also manifests in the
+-file names we use as we will see later.

+-NSS Basics
+-==========
+-
+- The basic idea is to put the implementation of the different services
+-offered to access the databases in separate modules. This has some
+-advantages:
+-
+- 1. Contributors can add new services without adding them to GNU C
+- Library.
+-
+- 2. The modules can be updated separately.
+-
+- 3. The C library image is smaller.
+-
+- To fulfill the first goal above the ABI of the modules will be
+-described below. For getting the implementation of a new service right
+-it is important to understand how the functions in the modules get
+-called. They are in no way designed to be used by the programmer
+-directly. Instead the programmer should only use the documented and
+-standardized functions to access the databases.
+-
+-The databases available in the NSS are
+-
+-`aliases'
+- Mail aliases
+-
+-`ethers'
+- Ethernet numbers,
+-
+-`group'
+- Groups of users, *note Group Database::.
+-
+-`hosts'
+- Host names and numbers, *note Host Names::.

+-
+-`rpc'
+- Remote procedure call names and numbers,
+-
+-`services'
+- Network services, *note Services Database::.

+-
+-The NSS Configuration File
+-==========================
+-
+- Somehow the NSS code must be told about the wishes of the user. For
+-this reason there is the file `/etc/nsswitch.conf'. For each database
+-this file contain a specification how the lookup process should work.
+-The file could look like this:
+-
+- # /etc/nsswitch.conf
+- #
+- # Name Service Switch configuration file.
+- #
+-
+- passwd: db files nis
+- shadow: files
+- group: db files nis
+-
+- hosts: files nisplus nis dns
+- networks: nisplus [NOTFOUND=return] files
+-
+- ethers: nisplus [NOTFOUND=return] db files
+- protocols: nisplus [NOTFOUND=return] db files
+- rpc: nisplus [NOTFOUND=return] db files
+- services: nisplus [NOTFOUND=return] db files
+-
+- The first column is the database as you can guess from the table
+-above. The rest of the line specifies how the lookup process works.
+-Please note that you specify the way it works for each database
+-individually. This cannot be done with the old way of a monolithic
+-implementation.
+-
+- The configuration specification for each database can contain two
+-different items:
+-
+- * the service specification like `files', `db', or `nis'.
+-
+- * the reaction on lookup result like `[NOTFOUND=return]'.

+-
+-Services in the NSS configuration File
+---------------------------------------
+-
+- The above example file mentions four different services: `files',
+-`db', `nis', and `nisplus'. This does not mean these services are
+-available on all sites and it does also not mean these are all the
+-services which will ever be available.
+-
+- In fact, these names are simply strings which the NSS code uses to
+-find the implicitly addressed functions. The internal interface will be
+-described later. Visible to the user are the modules which implement an
+-individual service.
+-
+- Assume the service NAME shall be used for a lookup. The code for
+-this service is implemented in a module called `libnss_NAME'. On a
+-system supporting shared libraries this is in fact a shared library
+-with the name (for example) `libnss_NAME.so.2'. The number at the end
+-is the currently used version of the interface which will not change
+-frequently. Normally the user should not have to be cognizant of these
+-files since they should be placed in a directory where they are found
+-automatically. Only the names of all available services are important.
+-
+-\1f
+-File: libc.info, Node: Actions in the NSS configuration, Next: Notes on NSS Configuration File, Prev: Services in the NSS configuration, Up: NSS Configuration File
+-
+-Actions in the NSS configuration
+---------------------------------
+-
+- The second item in the specification gives the user much finer
+-control on the lookup process. Action items are placed between two
+-service names and are written within brackets. The general form is
+-
+- `[' ( `!'? STATUS `=' ACTION )+ `]'
+-
+-where
+-
+- STATUS => success | notfound | unavail | tryagain
+- ACTION => return | continue
+-
+- The case of the keywords is insignificant. The STATUS values are
+-the results of a call to a lookup function of a specific service. They
+-mean
+-
+-`success'
+- No error occurred and the wanted entry is returned. The default
+- action for this is `return'.
+-
+-`notfound'
+- The lookup process works ok but the needed value was not found.
+- The default action is `continue'.
+-
+-`unavail'
+- The service is permanently unavailable. This can either mean the
+- needed file is not available, or, for DNS, the server is not
+- available or does not allow queries. The default action is
+- `continue'.
+-
+-`tryagain'
+- The service is temporarily unavailable. This could mean a file is
+- locked or a server currently cannot accept more connections. The
+- default action is `continue'.
+-
+-If we have a line like
+-
+- ethers: nisplus [NOTFOUND=return] db files
+-
+-this is equivalent to
+-
+- ethers: nisplus [SUCCESS=return NOTFOUND=return UNAVAIL=continue
+- TRYAGAIN=continue]
+- db [SUCCESS=return NOTFOUND=continue UNAVAIL=continue
+- TRYAGAIN=continue]
+- files
+-
+-(except that it would have to be written on one line). The default
+-value for the actions are normally what you want, and only need to be
+-changed in exceptional cases.
+-
+- If the optional `!' is placed before the STATUS this means the
+-following action is used for all statuses but STATUS itself. I.e., `!'
+-is negation as in the C language (and others).
+-
+- Before we explain the exception which makes this action item
+-necessary one more remark: obviously it makes no sense to add another
+-action item after the `files' service. Since there is no other service
+-following the action _always_ is `return'.
+-
+- Now, why is this `[NOTFOUND=return]' action useful? To understand
+-this we should know that the `nisplus' service is often complete; i.e.,
+-if an entry is not available in the NIS+ tables it is not available
+-anywhere else. This is what is expressed by this action item: it is
+-useless to examine further services since they will not give us a
+-result.
+-
+- The situation would be different if the NIS+ service is not available
+-because the machine is booting. In this case the return value of the
+-lookup function is not `notfound' but instead `unavail'. And as you
+-can see in the complete form above: in this situation the `db' and
+-`files' services are used. Neat, isn't it? The system administrator
+-need not pay special care for the time the system is not completely
+-ready to work (while booting or shutdown or network problems).
+-
+-\1f
+-File: libc.info, Node: Notes on NSS Configuration File, Prev: Actions in the NSS configuration, Up: NSS Configuration File
+-
+-Notes on the NSS Configuration File
+------------------------------------
+-
+- Finally a few more hints. The NSS implementation is not completely
+-helpless if `/etc/nsswitch.conf' does not exist. For all supported
+-databases there is a default value so it should normally be possible to
+-get the system running even if the file is corrupted or missing.
+-
+- For the `hosts' and `networks' databases the default value is `dns
+-[!UNAVAIL=return] files'. I.e., the system is prepared for the DNS
+-service not to be available but if it is available the answer it
+-returns is definitive.
+-
+- The `passwd', `group', and `shadow' databases are traditionally
+-handled in a special way. The appropriate files in the `/etc'
+-directory are read but if an entry with a name starting with a `+'
+-character is found NIS is used. This kind of lookup remains possible
+-by using the special lookup service `compat' and the default value for
+-the three databases above is `compat [NOTFOUND=return] files'.
+-
+- For all other databases the default value is `nis [NOTFOUND=return]
+-files'. This solution give the best chance to be correct since NIS and
+-file based lookup is used.
+-
+- A second point is that the user should try to optimize the lookup
+-process. The different service have different response times. A
+-simple file look up on a local file could be fast, but if the file is
+-long and the needed entry is near the end of the file this may take
+-quite some time. In this case it might be better to use the `db'
+-service which allows fast local access to large data sets.
+-
+- Often the situation is that some global information like NIS must be
+-used. So it is unavoidable to use service entries like `nis' etc. But
+-one should avoid slow services like this if possible.

+-NSS Module Internals
+-====================
+-
+- Now it is time to describe what the modules look like. The functions
+-contained in a module are identified by their names. I.e., there is no
+-jump table or the like. How this is done is of no interest here; those
+-interested in this topic should read about Dynamic Linking.

+-File: libc.info, Node: NSS Module Names, Next: NSS Modules Interface, Prev: NSS Module Internals, Up: NSS Module Internals
+-
+-The Naming Scheme of the NSS Modules
+-------------------------------------
+-
+-The name of each function consist of various parts:
+-
+- _nss_SERVICE_FUNCTION
+-
+- SERVICE of course corresponds to the name of the module this
+-function is found in.(1) The FUNCTION part is derived from the
+-interface function in the C library itself. If the user calls the
+-function `gethostbyname' and the service used is `files' the function
+-
+- _nss_files_gethostbyname_r
+-
+-in the module
+-
+- libnss_files.so.2
+-
+-is used. You see, what is explained above in not the whole truth. In
+-fact the NSS modules only contain reentrant versions of the lookup
+-functions. I.e., if the user would call the `gethostbyname_r' function
+-this also would end in the above function. For all user interface
+-functions the C library maps this call to a call to the reentrant
+-function. For reentrant functions this is trivial since the interface
+-is (nearly) the same. For the non-reentrant version The library keeps
+-internal buffers which are used to replace the user supplied buffer.
+-
+- I.e., the reentrant functions _can_ have counterparts. No service
+-module is forced to have functions for all databases and all kinds to
+-access them. If a function is not available it is simply treated as if
+-the function would return `unavail' (*note Actions in the NSS
+-configuration::).
+-
+- The file name `libnss_files.so.2' would be on a Solaris 2 system
+-`nss_files.so.2'. This is the difference mentioned above. Sun's NSS
+-modules are usable as modules which get indirectly loaded only.
+-
+- The NSS modules in the GNU C Library are prepared to be used as
+-normal libraries themselves. This is _not_ true at the moment, though.
+-However, the organization of the name space in the modules does not
+-make it impossible like it is for Solaris. Now you can see why the
+-modules are still libraries.(2)
+-
+- ---------- Footnotes ----------
+-
+- (1) Now you might ask why this information is duplicated. The
+-answer is that we want to make it possible to link directly with these
+-shared objects.
+-
+- (2) There is a second explanation: we were too lazy to change the
+-Makefiles to allow the generation of shared objects not starting with
+-`lib' but don't tell this to anybody.
+-
+-\1f
+-File: libc.info, Node: NSS Modules Interface, Prev: NSS Module Names, Up: NSS Module Internals
+-
+-The Interface of the Function in NSS Modules
+---------------------------------------------
+-
+- Now we know about the functions contained in the modules. It is now
+-time to describe the types. When we mentioned the reentrant versions of
+-the functions above, this means there are some additional arguments
+-(compared with the standard, non-reentrant version). The prototypes for
+-the non-reentrant and reentrant versions of our function above are:
+-
+- struct hostent *gethostbyname (const char *name)
+-
+- int gethostbyname_r (const char *name, struct hostent *result_buf,
+- char *buf, size_t buflen, struct hostent **result,
+- int *h_errnop)
+-
+-The actual prototype of the function in the NSS modules in this case is
+-
+- enum nss_status _nss_files_gethostbyname_r (const char *name,
+- struct hostent *result_buf,
+- char *buf, size_t buflen,
+- int *errnop, int *h_errnop)
+-
+- I.e., the interface function is in fact the reentrant function with
+-the change of the return value and the omission of the RESULT
+-parameter. While the user-level function returns a pointer to the
+-result the reentrant function return an `enum nss_status' value:
+-
+-`NSS_STATUS_TRYAGAIN'
+- numeric value `-2'
+-
+-`NSS_STATUS_UNAVAIL'
+- numeric value `-1'
+-
+-`NSS_STATUS_NOTFOUND'
+- numeric value `0'
+-
+-`NSS_STATUS_SUCCESS'
+- numeric value `1'
+-
+-Now you see where the action items of the `/etc/nsswitch.conf' file are
+-used.
+-
+- If you study the source code you will find there is a fifth value:
+-`NSS_STATUS_RETURN'. This is an internal use only value, used by a few
+-functions in places where none of the above value can be used. If
+-necessary the source code should be examined to learn about the details.
+-
+- In case the interface function has to return an error it is important
+-that the correct error code is stored in `*ERRNOP'. Some return status
+-value have only one associated error code, others have more.
+-
+-`NSS_STATUS_TRYAGAIN' `EAGAIN' One of the functions used ran
+- temporarily out of resources or a
+- service is currently not available.
+- `ERANGE' The provided buffer is not large
+- enough. The function should be
+- called again with a larger buffer.
+-`NSS_STATUS_UNAVAIL' `ENOENT' A necessary input file cannot be
+- found.
+-`NSS_STATUS_NOTFOUND' `ENOENT' The requested entry is not
+- available.
+-
+- These are proposed values. There can be other error codes and the
+-described error codes can have different meaning. *With one
+-exception:* when returning `NSS_STATUS_TRYAGAIN' the error code
+-`ERANGE' _must_ mean that the user provided buffer is too small.
+-Everything is non-critical.
+-
+- The above function has something special which is missing for almost
+-all the other module functions. There is an argument H_ERRNOP. This
+-points to a variable which will be filled with the error code in case
+-the execution of the function fails for some reason. The reentrant
+-function cannot use the global variable H_ERRNO; `gethostbyname' calls
+-`gethostbyname_r' with the last argument set to `&h_errno'.
+-
+- The `getXXXbyYYY' functions are the most important functions in the
+-NSS modules. But there are others which implement the other ways to
+-access system databases (say for the password database, there are
+-`setpwent', `getpwent', and `endpwent'). These will be described in
+-more detail later. Here we give a general way to determine the
+-signature of the module function:
+-
+- * the return value is `int';
+-
+- * the name is as explained in *note NSS Module Names::;
+-
+- * the first arguments are identical to the arguments of the
+- non-reentrant function;
+-
+- * the next three arguments are:
+-
+- `STRUCT_TYPE *result_buf'
+- pointer to buffer where the result is stored. `STRUCT_TYPE'
+- is normally a struct which corresponds to the database.
+-
+- `char *buffer'
+- pointer to a buffer where the function can store additional
+- data for the result etc.
+-
+- `size_t buflen'
+- length of the buffer pointed to by BUFFER.
+-
+- * possibly a last argument H_ERRNOP, for the host name and network
+- name lookup functions.
+-
+-This table is correct for all functions but the `set...ent' and
+-`end...ent' functions.

+-Extending NSS
+-=============
+-
+- One of the advantages of NSS mentioned above is that it can be
+-extended quite easily. There are two ways in which the extension can
+-happen: adding another database or adding another service. The former
+-is normally done only by the C library developers. It is here only
+-important to remember that adding another database is independent from
+-adding another service because a service need not support all databases
+-or lookup functions.
+-
+- A designer/implementor of a new service is therefore free to choose
+-the databases s/he is interested in and leave the rest for later (or
+-completely aside).

+- service functions.

+-
+-Adding another Service to NSS
+------------------------------
+-
+- The sources for a new service need not (and should not) be part of
+-the GNU C Library itself. The developer retains complete control over
+-the sources and its development. The links between the C library and
+-the new service module consists solely of the interface functions.
+-
+- Each module is designed following a specific interface specification.
+-For now the version is 2 (the interface in version 1 was not adequate)
+-and this manifests in the version number of the shared library object of
+-the NSS modules: they have the extension `.2'. If the interface
+-changes again in an incompatible way, this number will be increased.
+-Modules using the old interface will still be usable.
+-
+- Developers of a new service will have to make sure that their module
+-is created using the correct interface number. This means the file
+-itself must have the correct name and on ELF systems the "soname"
+-(Shared Object Name) must also have this number. Building a module
+-from a bunch of object files on an ELF system using GNU CC could be
+-done like this:
+-
+- gcc -shared -o libnss_NAME.so.2 -Wl,-soname,libnss_NAME.so.2 OBJECTS
+-
+-*Note Options for Linking: (gcc)Link Options, to learn more about this
+-command line.
+-
+- To use the new module the library must be able to find it. This can
+-be achieved by using options for the dynamic linker so that it will
+-search the directory where the binary is placed. For an ELF system
+-this could be done by adding the wanted directory to the value of
+-`LD_LIBRARY_PATH'.
+-
+- But this is not always possible since some programs (those which run
+-under IDs which do not belong to the user) ignore this variable.
+-Therefore the stable version of the module should be placed into a
+-directory which is searched by the dynamic linker. Normally this should
+-be the directory `$prefix/lib', where `$prefix' corresponds to the
+-value given to configure using the `--prefix' option. But be careful:
+-this should only be done if it is clear the module does not cause any
+-harm. System administrators should be careful.

+-
+-Internals of the NSS Module Functions
+--------------------------------------
+-
+- Until now we only provided the syntactic interface for the functions
+-in the NSS module. In fact there is not much more we can say since the
+-implementation obviously is different for each function. But a few
+-general rules must be followed by all functions.
+-
+- In fact there are four kinds of different functions which may appear
+-in the interface. All derive from the traditional ones for system
+-databases. DB in the following table is normally an abbreviation for
+-the database (e.g., it is `pw' for the password database).
+-
+-`enum nss_status _nss_DATABASE_setDBent (void)'
+- This function prepares the service for following operations. For a
+- simple file based lookup this means files could be opened, for
+- other services this function simply is a noop.
+-
+- One special case for this function is that it takes an additional
+- argument for some DATABASEs (i.e., the interface is `int setDBent
+- (int)'). *Note Host Names::, which describes the `sethostent'
+- function.
+-
+- The return value should be NSS_STATUS_SUCCESS or according to the
+- table above in case of an error (*note NSS Modules Interface::).
+-
+-`enum nss_status _nss_DATABASE_endDBent (void)'
+- This function simply closes all files which are still open or
+- removes buffer caches. If there are no files or buffers to remove
+- this is again a simple noop.
+-
+- There normally is no return value different to NSS_STATUS_SUCCESS.
+-
+-`enum nss_status _nss_DATABASE_getDBent_r (STRUCTURE *result, char *buffer, size_t buflen, int *errnop)'
+- Since this function will be called several times in a row to
+- retrieve one entry after the other it must keep some kind of
+- state. But this also means the functions are not really
+- reentrant. They are reentrant only in that simultaneous calls to
+- this function will not try to write the retrieved data in the same
+- place (as it would be the case for the non-reentrant functions);
+- instead, it writes to the structure pointed to by the RESULT
+- parameter. But the calls share a common state and in the case of
+- a file access this means they return neighboring entries in the
+- file.
+-
+- The buffer of length BUFLEN pointed to by BUFFER can be used for
+- storing some additional data for the result. It is _not_
+- guaranteed that the same buffer will be passed for the next call
+- of this function. Therefore one must not misuse this buffer to
+- save some state information from one call to another.
+-
+- Before the function returns the implementation should store the
+- value of the local ERRNO variable in the variable pointed to be
+- ERRNOP. This is important to guarantee the module working in
+- statically linked programs.
+-
+- As explained above this function could also have an additional last
+- argument. This depends on the database used; it happens only for
+- `host' and `networks'.
+-
+- The function shall return `NSS_STATUS_SUCCESS' as long as there are
+- more entries. When the last entry was read it should return
+- `NSS_STATUS_NOTFOUND'. When the buffer given as an argument is too
+- small for the data to be returned `NSS_STATUS_TRYAGAIN' should be
+- returned. When the service was not formerly initialized by a call
+- to `_nss_DATABASE_setDBent' all return value allowed for this
+- function can also be returned here.
+-
+-`enum nss_status _nss_DATABASE_getDBbyXX_r (PARAMS, STRUCTURE *result, char *buffer, size_t buflen, int *errnop)'
+- This function shall return the entry from the database which is
+- addressed by the PARAMS. The type and number of these arguments
+- vary. It must be individually determined by looking to the
+- user-level interface functions. All arguments given to the
+- non-reentrant version are here described by PARAMS.
+-
+- The result must be stored in the structure pointed to by RESULT.
+- If there is additional data to return (say strings, where the
+- RESULT structure only contains pointers) the function must use the
+- BUFFER or length BUFLEN. There must not be any references to
+- non-constant global data.
+-
+- The implementation of this function should honor the STAYOPEN flag
+- set by the `setDBent' function whenever this makes sense.
+-
+- Before the function returns the implementation should store the
+- value of the local ERRNO variable in the variable pointed to be
+- ERRNOP. This is important to guarantee the module working in
+- statically linked programs.
+-
+- Again, this function takes an additional last argument for the
+- `host' and `networks' database.
+-
+- The return value should as always follow the rules given above
+- (*note NSS Modules Interface::).

+-number called the "user ID". Each process has an effective user ID
+-which says which user's access permissions it has.

+-==================

+- Each user account on a computer system is identified by a "user

+-
+- Users are classified in "groups". Each user name belongs to one

+-
+-The Persona of a Process
+-========================
+-
+- At any time, each process has an "effective user ID", a "effective
+-group ID", and a set of "supplementary group IDs". These IDs determine
+-the privileges of the process. They are collectively called the
+-"persona" of the process, because they determine "who it is" for
+-purposes of access control.
+-
+- Your login shell starts out with a persona which consists of your
+-user ID, your default group ID, and your supplementary group IDs (if
+-you are in more than one group). In normal circumstances, all your
+-other processes inherit these values.
+-
+- A process also has a "real user ID" which identifies the user who
+-created the process, and a "real group ID" which identifies that user's
+-default group. These values do not play a role in access control, so
+-we do not consider them part of the persona. But they are also
+-important.
+-
+- Both the real and effective user ID can be changed during the
+-lifetime of a process. *Note Why Change Persona::.
+-
+- For details on how a process's effective user ID and group IDs affect
+-its permission to access files, see *Note Access Permission::.
+-
+- The effective user ID of a process also controls permissions for
+-sending signals using the `kill' function. *Note Signaling Another
+-Process::.
+-
+- Finally, there are many operations which can only be performed by a
+-process whose effective user ID is zero. A process with this user ID is
+-a "privileged process". Commonly the user name `root' is associated
+-with user ID 0, but there may be other user names with this ID.

+-
+-Why Change the Persona of a Process?
+-====================================
+-
+- The most obvious situation where it is necessary for a process to
+-change its user and/or group IDs is the `login' program. When `login'
+-starts running, its user ID is `root'. Its job is to start a shell
+-whose user and group IDs are those of the user who is logging in. (To
+-accomplish this fully, `login' must set the real user and group IDs as
+-well as its persona. But this is a special case.)
+-
+- The more common case of changing persona is when an ordinary user
+-program needs access to a resource that wouldn't ordinarily be
+-accessible to the user actually running it.
+-
+- For example, you may have a file that is controlled by your program
+-but that shouldn't be read or modified directly by other users, either
+-because it implements some kind of locking protocol, or because you want
+-to preserve the integrity or privacy of the information it contains.
+-This kind of restricted access can be implemented by having the program
+-change its effective user or group ID to match that of the resource.
+-
+- Thus, imagine a game program that saves scores in a file. The game
+-program itself needs to be able to update this file no matter who is
+-running it, but if users can write the file without going through the
+-game, they can give themselves any scores they like. Some people
+-consider this undesirable, or even reprehensible. It can be prevented
+-by creating a new user ID and login name (say, `games') to own the
+-scores file, and make the file writable only by this user. Then, when
+-the game program wants to update this file, it can change its effective
+-user ID to be that for `games'. In effect, the program must adopt the
+-persona of `games' so it can write the scores file.
+-

+-File: libc.info, Node: How Change Persona, Next: Reading Persona, Prev: Why Change Persona, Up: Users and Groups
+-
+-How an Application Can Change Persona
+-=====================================
+-
+- The ability to change the persona of a process can be a source of
+-unintentional privacy violations, or even intentional abuse. Because of
+-the potential for problems, changing persona is restricted to special
+-circumstances.
+-
+- You can't arbitrarily set your user ID or group ID to anything you
+-want; only privileged processes can do that. Instead, the normal way
+-for a program to change its persona is that it has been set up in
+-advance to change to a particular user or group. This is the function
+-of the setuid and setgid bits of a file's access mode. *Note
+-Permission Bits::.
+-
+- When the setuid bit of an executable file is on, executing that file
+-gives the process a third user ID: the "file user ID". This ID is set
+-to the owner ID of the file. The system then changes the effective
+-user ID to the file user ID. The real user ID remains as it was.
+-Likewise, if the setgid bit is on, the process is given a "file group
+-ID" equal to the group ID of the file, and its effective group ID is
+-changed to the file group ID.
+-
+- If a process has a file ID (user or group), then it can at any time
+-change its effective ID to its real ID and back to its file ID.
+-Programs use this feature to relinquish their special privileges except
+-when they actually need them. This makes it less likely that they can
+-be tricked into doing something inappropriate with their privileges.
+-
+- *Portability Note:* Older systems do not have file IDs. To
+-determine if a system has this feature, you can test the compiler
+-define `_POSIX_SAVED_IDS'. (In the POSIX standard, file IDs are known
+-as saved IDs.)
+-
+- *Note File Attributes::, for a more general discussion of file modes
+-and accessibility.

+-Reading the Persona of a Process
+-================================
+-
+- Here are detailed descriptions of the functions for reading the user
+-and group IDs of a process, both real and effective. To use these
+-facilities, you must include the header files `sys/types.h' and
+-`unistd.h'.
+-
+- - Data Type: uid_t
+- This is an integer data type used to represent user IDs. In the
+- GNU library, this is an alias for `unsigned int'.
+-
+- - Data Type: gid_t
+- This is an integer data type used to represent group IDs. In the
+- GNU library, this is an alias for `unsigned int'.
+-
+- - Function: uid_t getuid (void)
+- The `getuid' function returns the real user ID of the process.
+-
+- - Function: gid_t getgid (void)
+- The `getgid' function returns the real group ID of the process.
+-
+- - Function: uid_t geteuid (void)
+- The `geteuid' function returns the effective user ID of the
+- process.
+-
+- - Function: gid_t getegid (void)
+- The `getegid' function returns the effective group ID of the
+- process.
+-
+- - Function: int getgroups (int COUNT, gid_t *GROUPS)
+- The `getgroups' function is used to inquire about the supplementary
+- group IDs of the process. Up to COUNT of these group IDs are
+- stored in the array GROUPS; the return value from the function is
+- the number of group IDs actually stored. If COUNT is smaller than
+- the total number of supplementary group IDs, then `getgroups'
+- returns a value of `-1' and `errno' is set to `EINVAL'.
+-
+- If COUNT is zero, then `getgroups' just returns the total number
+- of supplementary group IDs. On systems that do not support
+- supplementary groups, this will always be zero.
+-
+- Here's how to use `getgroups' to read all the supplementary group
+- IDs:
+-
+- gid_t *
+- read_all_groups (void)
+- {
+- int ngroups = getgroups (0, NULL);
+- gid_t *groups
+- = (gid_t *) xmalloc (ngroups * sizeof (gid_t));
+- int val = getgroups (ngroups, groups);
+- if (val < 0)
+- {
+- free (groups);

+- }
+- return groups;
+- }

+-
+-Setting the User ID
+-===================
+-
+- This section describes the functions for altering the user ID (real
+-and/or effective) of a process. To use these facilities, you must
+-include the header files `sys/types.h' and `unistd.h'.
+-
+- - Function: int seteuid (uid_t NEWEUID)
+- This function sets the effective user ID of a process to NEWUID,
+- provided that the process is allowed to change its effective user
+- ID. A privileged process (effective user ID zero) can change its
+- effective user ID to any legal value. An unprivileged process
+- with a file user ID can change its effective user ID to its real
+- user ID or to its file user ID. Otherwise, a process may not
+- change its effective user ID at all.
+-
+- The `seteuid' function returns a value of `0' to indicate
+- successful completion, and a value of `-1' to indicate an error.
+- The following `errno' error conditions are defined for this
+- function:
+-
+- `EINVAL'
+- The value of the NEWUID argument is invalid.
+-
+- `EPERM'
+- The process may not change to the specified ID.
+-
+- Older systems (those without the `_POSIX_SAVED_IDS' feature) do not
+- have this function.
+-
+- - Function: int setuid (uid_t NEWUID)
+- If the calling process is privileged, this function sets both the
+- real and effective user ID of the process to NEWUID. It also
+- deletes the file user ID of the process, if any. NEWUID may be any
+- legal value. (Once this has been done, there is no way to recover
+- the old effective user ID.)
+-
+- If the process is not privileged, and the system supports the
+- `_POSIX_SAVED_IDS' feature, then this function behaves like
+- `seteuid'.
+-
+- The return values and error conditions are the same as for
+- `seteuid'.
+-
+- - Function: int setreuid (uid_t RUID, uid_t EUID)
+- This function sets the real user ID of the process to RUID and the
+- effective user ID to EUID. If RUID is `-1', it means not to
+- change the real user ID; likewise if EUID is `-1', it means not to
+- change the effective user ID.
+-
+- The `setreuid' function exists for compatibility with 4.3 BSD Unix,
+- which does not support file IDs. You can use this function to
+- swap the effective and real user IDs of the process. (Privileged
+- processes are not limited to this particular usage.) If file IDs
+- are supported, you should use that feature instead of this
+- function. *Note Enable/Disable Setuid::.
+-
+- The return value is `0' on success and `-1' on failure. The
+- following `errno' error conditions are defined for this function:
+-
+- `EPERM'
+- The process does not have the appropriate privileges; you do
+- not have permission to change to the specified ID.
+-

+-
+-Setting the Group IDs
+-=====================
+-
+- This section describes the functions for altering the group IDs (real
+-and effective) of a process. To use these facilities, you must include
+-the header files `sys/types.h' and `unistd.h'.
+-
+- - Function: int setegid (gid_t NEWGID)
+- This function sets the effective group ID of the process to
+- NEWGID, provided that the process is allowed to change its group
+- ID. Just as with `seteuid', if the process is privileged it may
+- change its effective group ID to any value; if it isn't, but it
+- has a file group ID, then it may change to its real group ID or
+- file group ID; otherwise it may not change its effective group ID.
+-
+- Note that a process is only privileged if its effective _user_ ID
+- is zero. The effective group ID only affects access permissions.
+-
+- The return values and error conditions for `setegid' are the same
+- as those for `seteuid'.
+-
+- This function is only present if `_POSIX_SAVED_IDS' is defined.
+-
+- - Function: int setgid (gid_t NEWGID)
+- This function sets both the real and effective group ID of the
+- process to NEWGID, provided that the process is privileged. It
+- also deletes the file group ID, if any.
+-
+- If the process is not privileged, then `setgid' behaves like
+- `setegid'.
+-
+- The return values and error conditions for `setgid' are the same
+- as those for `seteuid'.
+-
+- - Function: int setregid (gid_t RGID, gid_t EGID)
+- This function sets the real group ID of the process to RGID and
+- the effective group ID to EGID. If RGID is `-1', it means not to
+- change the real group ID; likewise if EGID is `-1', it means not
+- to change the effective group ID.
+-
+- The `setregid' function is provided for compatibility with 4.3 BSD
+- Unix, which does not support file IDs. You can use this function
+- to swap the effective and real group IDs of the process.
+- (Privileged processes are not limited to this usage.) If file IDs
+- are supported, you should use that feature instead of using this
+- function. *Note Enable/Disable Setuid::.
+-
+- The return values and error conditions for `setregid' are the same
+- as those for `setreuid'.
+-
+- `setuid' and `setgid' behave differently depending on whether the
+-effective user ID at the time is zero. If it is not zero, they behave
+-like `seteuid' and `setegid'. If it is, they change both effective and
+-real IDs and delete the file ID. To avoid confusion, we recommend you
+-always use `seteuid' and `setegid' except when you know the effective
+-user ID is zero and your intent is to change the persona permanently.
+-This case is rare--most of the programs that need it, such as `login'
+-and `su', have already been written.
+-
+- Note that if your program is setuid to some user other than `root',
+-there is no way to drop privileges permanently.
+-
+- The system also lets privileged processes change their supplementary
+-group IDs. To use `setgroups' or `initgroups', your programs should
+-include the header file `grp.h'.
+-
+- - Function: int setgroups (size_t COUNT, gid_t *GROUPS)
+- This function sets the process's supplementary group IDs. It can
+- only be called from privileged processes. The COUNT argument
+- specifies the number of group IDs in the array GROUPS.
+-
+- This function returns `0' if successful and `-1' on error. The
+- following `errno' error conditions are defined for this function:
+-
+- `EPERM'
+- The calling process is not privileged.
+-
+- - Function: int initgroups (const char *USER, gid_t GROUP)
+- The `initgroups' function sets the process's supplementary group
+- IDs to be the normal default for the user name USER. The group
+- GROUP is automatically included.
+-
+- This function works by scanning the group database for all the
+- groups USER belongs to. It then calls `setgroups' with the list it
+- has constructed.
+-
+- The return values and error conditions are the same as for
+- `setgroups'.
+-
+- If you are interested in the groups a particular user belongs to,
+-but do not want to change the process's supplementary group IDs, you
+-can use `getgrouplist'. To use `getgrouplist', your programs should
+-include the header file `grp.h'.
+-
+- - Function: int getgrouplist (const char *USER, gid_t GROUP, gid_t
+- *GROUPS, int *NGROUPS)
+- The `getgrouplist' function scans the group database for all the
+- groups USER belongs to. Up to *NGROUPS group IDs corresponding to
+- these groups are stored in the array GROUPS; the return value from
+- the function is the number of group IDs actually stored. If
+- *NGROUPS is smaller than the total number of groups found, then
+- `getgrouplist' returns a value of `-1' and stores the actual
+- number of groups in *NGROUPS. The group GROUP is automatically
+- included in the list of groups returned by `getgrouplist'.
+-
+- Here's how to use `getgrouplist' to read all supplementary groups
+- for USER:
+-
+- gid_t *
+- supplementary_groups (char *user)
+- {
+- int ngroups = 16;
+- gid_t *groups
+- = (gid_t *) xmalloc (ngroups * sizeof (gid_t));
+- struct passwd *pw = getpwnam (user);
+-
+- if (pw == NULL)
+- return NULL;
+-
+- if (getgrouplist (pw->pw_name, pw->pw_gid, groups, &ngroups) < 0)
+- {
+- groups = xrealloc (ngroups * sizeof (gid_t));
+- getgrouplist (pw->pw_name, pw->pw_gid, groups, &ngroups);
+- }
+- return groups;
+- }

+-
+-Enabling and Disabling Setuid Access
+-====================================
+-
+- A typical setuid program does not need its special access all of the
+-time. It's a good idea to turn off this access when it isn't needed,
+-so it can't possibly give unintended access.
+-
+- If the system supports the `_POSIX_SAVED_IDS' feature, you can
+-accomplish this with `seteuid'. When the game program starts, its real
+-user ID is `jdoe', its effective user ID is `games', and its saved user
+-ID is also `games'. The program should record both user ID values once
+-at the beginning, like this:
+-
+- user_user_id = getuid ();
+- game_user_id = geteuid ();
+-
+- Then it can turn off game file access with
+-
+- seteuid (user_user_id);
+-
+-and turn it on with
+-
+- seteuid (game_user_id);
+-
+-Throughout this process, the real user ID remains `jdoe' and the file
+-user ID remains `games', so the program can always set its effective
+-user ID to either one.
+-
+- On other systems that don't support file user IDs, you can turn
+-setuid access on and off by using `setreuid' to swap the real and
+-effective user IDs of the process, as follows:
+-
+- setreuid (geteuid (), getuid ());
+-
+-This special case is always allowed--it cannot fail.
+-
+- Why does this have the effect of toggling the setuid access?
+-Suppose a game program has just started, and its real user ID is `jdoe'
+-while its effective user ID is `games'. In this state, the game can
+-write the scores file. If it swaps the two uids, the real becomes
+-`games' and the effective becomes `jdoe'; now the program has only
+-`jdoe' access. Another swap brings `games' back to the effective user
+-ID and restores access to the scores file.
+-
+- In order to handle both kinds of systems, test for the saved user ID
+-feature with a preprocessor conditional, like this:
+-
+- #ifdef _POSIX_SAVED_IDS
+- seteuid (user_user_id);
+- #else
+- setreuid (geteuid (), getuid ());
+- #endif

+-
+-Setuid Program Example
+-======================
+-
+- Here's an example showing how to set up a program that changes its
+-effective user ID.
+-
+- This is part of a game program called `caber-toss' that manipulates
+-a file `scores' that should be writable only by the game program
+-itself. The program assumes that its executable file will be installed
+-with the setuid bit set and owned by the same user as the `scores'
+-file. Typically, a system administrator will set up an account like
+-`games' for this purpose.
+-
+- The executable file is given mode `4755', so that doing an `ls -l'
+-on it produces output like:
+-
+- -rwsr-xr-x 1 games 184422 Jul 30 15:17 caber-toss
+-
+-The setuid bit shows up in the file modes as the `s'.
+-
+- The scores file is given mode `644', and doing an `ls -l' on it
+-shows:
+-
+- -rw-r--r-- 1 games 0 Jul 31 15:33 scores
+-
+- Here are the parts of the program that show how to set up the changed
+-user ID. This program is conditionalized so that it makes use of the
+-file IDs feature if it is supported, and otherwise uses `setreuid' to
+-swap the effective and real user IDs.
+-
+- #include <stdio.h>
+- #include <sys/types.h>
+- #include <unistd.h>
+- #include <stdlib.h>
+-
+-
+- /* Remember the effective and real UIDs. */
+-
+- static uid_t euid, ruid;
+-
+-
+- /* Restore the effective UID to its original value. */
+-
+- void
+- do_setuid (void)
+- {
+- int status;
+-
+- #ifdef _POSIX_SAVED_IDS
+- status = seteuid (euid);
+- #else
+- status = setreuid (ruid, euid);
+- #endif
+- if (status < 0) {
+- fprintf (stderr, "Couldn't set uid.\n");
+- exit (status);
+- }
+- }
+-
+-
+- /* Set the effective UID to the real UID. */
+-
+- void
+- undo_setuid (void)
+- {
+- int status;
+-
+- #ifdef _POSIX_SAVED_IDS
+- status = seteuid (ruid);

+- /* Remember the real and effective user IDs. */
+- ruid = getuid ();
+- euid = geteuid ();
+- undo_setuid ();
+-
+- /* Do the game and record the score. */
+- ...
+- }
+-
+- Notice how the first thing the `main' function does is to set the
+-effective user ID back to the real user ID. This is so that any other
+-file accesses that are performed while the user is playing the game use
+-the real user ID for determining permissions. Only when the program
+-needs to open the scores file does it switch back to the file user ID,
+-like this:
+-
+- /* Record the score. */
+-
+- int
+- record_score (int score)
+- {
+- FILE *stream;
+- char *myname;
+-
+- /* Open the scores file. */
+- do_setuid ();
+- stream = fopen (SCORES_FILE, "a");
+- undo_setuid ();
+-
+- /* Write the score to the file. */

+- {
+- myname = cuserid (NULL);
+- if (score < 0)
+- fprintf (stream, "%10s: Couldn't lift the caber.\n", myname);
+- else

+-Tips for Writing Setuid Programs
+-================================
+-
+- It is easy for setuid programs to give the user access that isn't
+-intended--in fact, if you want to avoid this, you need to be careful.
+-Here are some guidelines for preventing unintended access and
+-minimizing its consequences when it does occur:
+-
+- * Don't have `setuid' programs with privileged user IDs such as
+- `root' unless it is absolutely necessary. If the resource is
+- specific to your particular program, it's better to define a new,
+- nonprivileged user ID or group ID just to manage that resource.
+- It's better if you can write your program to use a special group
+- than a special user.
+-
+- * Be cautious about using the `exec' functions in combination with
+- changing the effective user ID. Don't let users of your program
+- execute arbitrary programs under a changed user ID. Executing a
+- shell is especially bad news. Less obviously, the `execlp' and
+- `execvp' functions are a potential risk (since the program they
+- execute depends on the user's `PATH' environment variable).
+-
+- If you must `exec' another program under a changed ID, specify an
+- absolute file name (*note File Name Resolution::) for the
+- executable, and make sure that the protections on that executable
+- and _all_ containing directories are such that ordinary users
+- cannot replace it with some other program.
+-
+- You should also check the arguments passed to the program to make
+- sure they do not have unexpected effects. Likewise, you should
+- examine the environment variables. Decide which arguments and
+- variables are safe, and reject all others.
+-
+- You should never use `system' in a privileged program, because it
+- invokes a shell.
+-
+- * Only use the user ID controlling the resource in the part of the
+- program that actually uses that resource. When you're finished
+- with it, restore the effective user ID back to the actual user's
+- user ID. *Note Enable/Disable Setuid::.
+-
+- * If the `setuid' part of your program needs to access other files
+- besides the controlled resource, it should verify that the real
+- user would ordinarily have permission to access those files. You
+- can use the `access' function (*note Access Permission::) to check
+- this; it uses the real user and group IDs, rather than the
+- effective IDs.

+-Identifying Who Logged In
+-=========================
+-
+- You can use the functions listed in this section to determine the
+-login name of the user who is running a process, and the name of the
+-user who logged in the current session. See also the function `getuid'
+-and friends (*note Reading Persona::). How this information is
+-collected by the system and how to control/add/remove information from
+-the background storage is described in *Note User Accounting Database::.
+-
+- The `getlogin' function is declared in `unistd.h', while `cuserid'
+-and `L_cuserid' are declared in `stdio.h'.
+-
+- - Function: char * getlogin (void)
+- The `getlogin' function returns a pointer to a string containing
+- the name of the user logged in on the controlling terminal of the
+- process, or a null pointer if this information cannot be
+- determined. The string is statically allocated and might be
+- overwritten on subsequent calls to this function or to `cuserid'.
+-
+- - Function: char * cuserid (char *STRING)
+- The `cuserid' function returns a pointer to a string containing a
+- user name associated with the effective ID of the process. If
+- STRING is not a null pointer, it should be an array that can hold
+- at least `L_cuserid' characters; the string is returned in this
+- array. Otherwise, a pointer to a string in a static area is
+- returned. This string is statically allocated and might be
+- overwritten on subsequent calls to this function or to `getlogin'.
+-
+- The use of this function is deprecated since it is marked to be
+- withdrawn in XPG4.2 and has already been removed from newer
+- revisions of POSIX.1.
+-
+- - Macro: int L_cuserid
+- An integer constant that indicates how long an array you might
+- need to store a user name.
+-
+- These functions let your program identify positively the user who is
+-running or the user who logged in this session. (These can differ when
+-setuid programs are involved; see *Note Process Persona::.) The user
+-cannot do anything to fool these functions.
+-
+- For most purposes, it is more useful to use the environment variable
+-`LOGNAME' to find out who the user is. This is more flexible precisely
+-because the user can set `LOGNAME' arbitrarily. *Note Standard
+-Environment::.

+-The User Accounting Database
+-============================
+-
+- Most Unix-like operating systems keep track of logged in users by

+-about the run level of the system, the time of the last system reboot,
+-and possibly more.
+-
+- The user accounting database typically lives in `/etc/utmp',
+-`/var/adm/utmp' or `/var/run/utmp'. However, these files should

+-Manipulating the User Accounting Database
+------------------------------------------
+-
+- These functions and the corresponding data structures are declared in
+-the header file `utmp.h'.
+-
+- - Data Type: struct exit_status
+- The `exit_status' data structure is used to hold information about
+- the exit status of processes marked as `DEAD_PROCESS' in the user
+- accounting database.
+-
+- `short int e_termination'
+- The exit status of the process.
+-
+- `short int e_exit'
+- The exit status of the process.
+-
+- - Data Type: struct utmp
+- The `utmp' data structure is used to hold information about entries
+- in the user accounting database. On the GNU system it has the
+- following members:
+-
+- `short int ut_type'
+- Specifies the type of login; one of `EMPTY', `RUN_LVL',
+- `BOOT_TIME', `OLD_TIME', `NEW_TIME', `INIT_PROCESS',
+- `LOGIN_PROCESS', `USER_PROCESS', `DEAD_PROCESS' or
+- `ACCOUNTING'.
+-
+- `pid_t ut_pid'
+- The process ID number of the login process.
+-
+- `char ut_line[]'
+- The device name of the tty (without `/dev/').
+-
+- `char ut_id[]'
+- The inittab ID of the process.
+-
+- `char ut_user[]'
+- The user's login name.
+-
+- `char ut_host[]'
+- The name of the host from which the user logged in.
+-
+- `struct exit_status ut_exit'
+- The exit status of a process marked as `DEAD_PROCESS'.
+-
+- `long ut_session'
+- The Session ID, used for windowing.
+-
+- `struct timeval ut_tv'
+- Time the entry was made. For entries of type `OLD_TIME' this
+- is the time when the system clock changed, and for entries of
+- type `NEW_TIME' this is the time the system clock was set to.
+-
+- `int32_t ut_addr_v6[4]'
+- The Internet address of a remote host.
+-
+- The `ut_type', `ut_pid', `ut_id', `ut_tv', and `ut_host' fields are
+-not available on all systems. Portable applications therefore should
+-be prepared for these situations. To help doing this the `utmp.h'
+-header provides macros `_HAVE_UT_TYPE', `_HAVE_UT_PID', `_HAVE_UT_ID',
+-`_HAVE_UT_TV', and `_HAVE_UT_HOST' if the respective field is
+-available. The programmer can handle the situations by using `#ifdef'
+-in the program code.
+-
+- The following macros are defined for use as values for the `ut_type'
+-member of the `utmp' structure. The values are integer constants.
+-
+-`EMPTY'
+- This macro is used to indicate that the entry contains no valid
+- user accounting information.
+-
+-`RUN_LVL'
+- This macro is used to identify the systems runlevel.
+-
+-`BOOT_TIME'
+- This macro is used to identify the time of system boot.
+-
+-`OLD_TIME'
+- This macro is used to identify the time when the system clock
+- changed.
+-
+-`NEW_TIME'
+- This macro is used to identify the time after the system changed.
+-
+-`INIT_PROCESS'
+- This macro is used to identify a process spawned by the init
+- process.
+-
+-`LOGIN_PROCESS'
+- This macro is used to identify the session leader of a logged in
+- user.
+-
+-`USER_PROCESS'
+- This macro is used to identify a user process.
+-
+-`DEAD_PROCESS'
+- This macro is used to identify a terminated process.
+-
+-`ACCOUNTING'
+- ???
+-
+- The size of the `ut_line', `ut_id', `ut_user' and `ut_host' arrays
+-can be found using the `sizeof' operator.
+-
+- Many older systems have, instead of an `ut_tv' member, an `ut_time'
+-member, usually of type `time_t', for representing the time associated
+-with the entry. Therefore, for backwards compatibility only, `utmp.h'
+-defines `ut_time' as an alias for `ut_tv.tv_sec'.
+-
+- - Function: void setutent (void)
+- This function opens the user accounting database to begin scanning
+- it. You can then call `getutent', `getutid' or `getutline' to
+- read entries and `pututline' to write entries.
+-
+- If the database is already open, it resets the input to the
+- beginning of the database.
+-
+- - Function: struct utmp * getutent (void)
+- The `getutent' function reads the next entry from the user
+- accounting database. It returns a pointer to the entry, which is
+- statically allocated and may be overwritten by subsequent calls to
+- `getutent'. You must copy the contents of the structure if you
+- wish to save the information or you can use the `getutent_r'
+- function which stores the data in a user-provided buffer.
+-
+- A null pointer is returned in case no further entry is available.
+-
+- - Function: void endutent (void)
+- This function closes the user accounting database.
+-
+- - Function: struct utmp * getutid (const struct utmp *ID)
+- This function searches forward from the current point in the
+- database for an entry that matches ID. If the `ut_type' member of
+- the ID structure is one of `RUN_LVL', `BOOT_TIME', `OLD_TIME' or
+- `NEW_TIME' the entries match if the `ut_type' members are
+- identical. If the `ut_type' member of the ID structure is
+- `INIT_PROCESS', `LOGIN_PROCESS', `USER_PROCESS' or `DEAD_PROCESS',
+- the entries match if the `ut_type' member of the entry read from
+- the database is one of these four, and the `ut_id' members match.
+- However if the `ut_id' member of either the ID structure or the
+- entry read from the database is empty it checks if the `ut_line'
+- members match instead. If a matching entry is found, `getutid'
+- returns a pointer to the entry, which is statically allocated, and
+- may be overwritten by a subsequent call to `getutent', `getutid'
+- or `getutline'. You must copy the contents of the structure if
+- you wish to save the information.
+-
+- A null pointer is returned in case the end of the database is
+- reached without a match.
+-
+- The `getutid' function may cache the last read entry. Therefore,
+- if you are using `getutid' to search for multiple occurrences, it
+- is necessary to zero out the static data after each call.
+- Otherwise `getutid' could just return a pointer to the same entry
+- over and over again.
+-
+- - Function: struct utmp * getutline (const struct utmp *LINE)
+- This function searches forward from the current point in the
+- database until it finds an entry whose `ut_type' value is
+- `LOGIN_PROCESS' or `USER_PROCESS', and whose `ut_line' member
+- matches the `ut_line' member of the LINE structure. If it finds
+- such an entry, it returns a pointer to the entry which is
+- statically allocated, and may be overwritten by a subsequent call
+- to `getutent', `getutid' or `getutline'. You must copy the
+- contents of the structure if you wish to save the information.
+-
+- A null pointer is returned in case the end of the database is
+- reached without a match.
+-
+- The `getutline' function may cache the last read entry. Therefore
+- if you are using `getutline' to search for multiple occurrences, it
+- is necessary to zero out the static data after each call.
+- Otherwise `getutline' could just return a pointer to the same
+- entry over and over again.
+-
+- - Function: struct utmp * pututline (const struct utmp *UTMP)
+- The `pututline' function inserts the entry `*UTMP' at the
+- appropriate place in the user accounting database. If it finds
+- that it is not already at the correct place in the database, it
+- uses `getutid' to search for the position to insert the entry,
+- however this will not modify the static structure returned by
+- `getutent', `getutid' and `getutline'. If this search fails, the
+- entry is appended to the database.
+-
+- The `pututline' function returns a pointer to a copy of the entry
+- inserted in the user accounting database, or a null pointer if the
+- entry could not be added. The following `errno' error conditions
+- are defined for this function:
+-
+- `EPERM'
+- The process does not have the appropriate privileges; you
+- cannot modify the user accounting database.
+-
+- All the `get*' functions mentioned before store the information they
+-return in a static buffer. This can be a problem in multi-threaded
+-programs since the data returned for the request is overwritten by the
+-return value data in another thread. Therefore the GNU C Library
+-provides as extensions three more functions which return the data in a
+-user-provided buffer.
+-
+- - Function: int getutent_r (struct utmp *BUFFER, struct utmp **RESULT)
+- The `getutent_r' is equivalent to the `getutent' function. It
+- returns the next entry from the database. But instead of storing
+- the information in a static buffer it stores it in the buffer
+- pointed to by the parameter BUFFER.
+-
+- If the call was successful, the function returns `0' and the
+- pointer variable pointed to by the parameter RESULT contains a
+- pointer to the buffer which contains the result (this is most
+- probably the same value as BUFFER). If something went wrong
+- during the execution of `getutent_r' the function returns `-1'.
+-
+- This function is a GNU extension.
+-
+- - Function: int getutid_r (const struct utmp *ID, struct utmp *BUFFER,
+- struct utmp **RESULT)
+- This function retrieves just like `getutid' the next entry matching
+- the information stored in ID. But the result is stored in the
+- buffer pointed to by the parameter BUFFER.
+-
+- If successful the function returns `0' and the pointer variable
+- pointed to by the parameter RESULT contains a pointer to the
+- buffer with the result (probably the same as RESULT. If not
+- successful the function return `-1'.
+-
+- This function is a GNU extension.
+-
+- - Function: int getutline_r (const struct utmp *LINE, struct utmp
+- *BUFFER, struct utmp **RESULT)
+- This function retrieves just like `getutline' the next entry
+- matching the information stored in LINE. But the result is stored
+- in the buffer pointed to by the parameter BUFFER.
+-
+- If successful the function returns `0' and the pointer variable
+- pointed to by the parameter RESULT contains a pointer to the
+- buffer with the result (probably the same as RESULT. If not
+- successful the function return `-1'.
+-
+- This function is a GNU extension.
+-
+- In addition to the user accounting database, most systems keep a
+-number of similar databases. For example most systems keep a log file
+-with all previous logins (usually in `/etc/wtmp' or `/var/log/wtmp').
+-
+- For specifying which database to examine, the following function
+-should be used.
+-
+- - Function: int utmpname (const char *FILE)
+- The `utmpname' function changes the name of the database to be
+- examined to FILE, and closes any previously opened database. By
+- default `getutent', `getutid', `getutline' and `pututline' read
+- from and write to the user accounting database.
+-
+- The following macros are defined for use as the FILE argument:
+-
+- - Macro: char * _PATH_UTMP
+- This macro is used to specify the user accounting database.
+-
+- - Macro: char * _PATH_WTMP
+- This macro is used to specify the user accounting log file.
+-
+- The `utmpname' function returns a value of `0' if the new name was
+- successfully stored, and a value of `-1' to indicate an error.
+- Note that `utmpname' does not try to open the database, and that
+- therefore the return value does not say anything about whether the
+- database can be successfully opened.
+-
+- Specially for maintaining log-like databases the GNU C Library
+-provides the following function:
+-
+- - Function: void updwtmp (const char *WTMP_FILE, const struct utmp
+- *UTMP)
+- The `updwtmp' function appends the entry *UTMP to the database
+- specified by WTMP_FILE. For possible values for the WTMP_FILE
+- argument see the `utmpname' function.
+-
+- *Portability Note:* Although many operating systems provide a subset
+-of these functions, they are not standardized. There are often subtle
+-differences in the return types, and there are considerable differences
+-between the various definitions of `struct utmp'. When programming for
+-the GNU system, it is probably best to stick with the functions
+-described in this section. If however, you want your program to be
+-portable, consider using the XPG functions described in *Note XPG
+-Functions::, or take a look at the BSD compatible functions in *Note
+-Logging In and Out::.

+-XPG User Accounting Database Functions
+---------------------------------------
+-
+- These functions, described in the X/Open Portability Guide, are
+-declared in the header file `utmpx.h'.
+-
+- - Data Type: struct utmpx
+- The `utmpx' data structure contains at least the following members:
+-
+- `short int ut_type'
+- Specifies the type of login; one of `EMPTY', `RUN_LVL',
+- `BOOT_TIME', `OLD_TIME', `NEW_TIME', `INIT_PROCESS',
+- `LOGIN_PROCESS', `USER_PROCESS' or `DEAD_PROCESS'.
+-
+- `pid_t ut_pid'
+- The process ID number of the login process.
+-
+- `char ut_line[]'
+- The device name of the tty (without `/dev/').
+-
+- `char ut_id[]'
+- The inittab ID of the process.
+-
+- `char ut_user[]'
+- The user's login name.
+-
+- `struct timeval ut_tv'
+- Time the entry was made. For entries of type `OLD_TIME' this
+- is the time when the system clock changed, and for entries of
+- type `NEW_TIME' this is the time the system clock was set to.
+- On the GNU system, `struct utmpx' is identical to `struct utmp'
+- except for the fact that including `utmpx.h' does not make visible
+- the declaration of `struct exit_status'.
+-
+- The following macros are defined for use as values for the `ut_type'
+-member of the `utmpx' structure. The values are integer constants and
+-are, on the GNU system, identical to the definitions in `utmp.h'.
+-
+-`EMPTY'
+- This macro is used to indicate that the entry contains no valid
+- user accounting information.
+-
+-`RUN_LVL'
+- This macro is used to identify the systems runlevel.
+-
+-`BOOT_TIME'
+- This macro is used to identify the time of system boot.
+-
+-`OLD_TIME'
+- This macro is used to identify the time when the system clock
+- changed.
+-
+-`NEW_TIME'
+- This macro is used to identify the time after the system changed.
+-
+-`INIT_PROCESS'
+- This macro is used to identify a process spawned by the init
+- process.
+-
+-`LOGIN_PROCESS'
+- This macro is used to identify the session leader of a logged in
+- user.
+-
+-`USER_PROCESS'
+- This macro is used to identify a user process.
+-
+-`DEAD_PROCESS'
+- This macro is used to identify a terminated process.
+-
+- The size of the `ut_line', `ut_id' and `ut_user' arrays can be found
+-using the `sizeof' operator.
+-
+- - Function: void setutxent (void)
+- This function is similar to `setutent'. On the GNU system it is
+- simply an alias for `setutent'.
+-
+- - Function: struct utmpx * getutxent (void)
+- The `getutxent' function is similar to `getutent', but returns a
+- pointer to a `struct utmpx' instead of `struct utmp'. On the GNU
+- system it simply is an alias for `getutent'.
+-
+- - Function: void endutxent (void)
+- This function is similar to `endutent'. On the GNU system it is
+- simply an alias for `endutent'.
+-
+- - Function: struct utmpx * getutxid (const struct utmpx *ID)
+- This function is similar to `getutid', but uses `struct utmpx'
+- instead of `struct utmp'. On the GNU system it is simply an alias
+- for `getutid'.
+-
+- - Function: struct utmpx * getutxline (const struct utmpx *LINE)
+- This function is similar to `getutid', but uses `struct utmpx'
+- instead of `struct utmp'. On the GNU system it is simply an alias
+- for `getutline'.
+-
+- - Function: struct utmpx * pututxline (const struct utmpx *UTMP)
+- The `pututxline' function is functionally identical to
+- `pututline', but uses `struct utmpx' instead of `struct utmp'. On
+- the GNU system, `pututxline' is simply an alias for `pututline'.
+-
+- - Function: int utmpxname (const char *FILE)
+- The `utmpxname' function is functionally identical to `utmpname'.
+- On the GNU system, `utmpxname' is simply an alias for `utmpname'.
+-
+- You can translate between a traditional `struct utmp' and an XPG
+-`struct utmpx' with the following functions. On the GNU system, these
+-functions are merely copies, since the two structures are identical.
+-
+- - Function: int getutmp (const struct utmpx *utmpx, struct utmp *utmp)
+- `getutmp' copies the information, insofar as the structures are
+- compatible, from UTMPX to UTMP.
+-
+- - Function: int getutmpx (const struct utmp *utmp, struct utmpx *utmpx)
+- `getutmpx' copies the information, insofar as the structures are
+- compatible, from UTMP to UTMPX.

+-
+-Logging In and Out
+-------------------
+-
+- These functions, derived from BSD, are available in the separate
+-`libutil' library, and declared in `utmp.h'.
+-
+- Note that the `ut_user' member of `struct utmp' is called `ut_name'
+-in BSD. Therefore, `ut_name' is defined as an alias for `ut_user' in
+-`utmp.h'.
+-
+- - Function: int login_tty (int FILEDES)
+- This function makes FILEDES the controlling terminal of the
+- current process, redirects standard input, standard output and
+- standard error output to this terminal, and closes FILEDES.
+-
+- This function returns `0' on successful completion, and `-1' on
+- error.
+-
+- - Function: void login (const struct utmp *ENTRY)
+- The `login' functions inserts an entry into the user accounting
+- database. The `ut_line' member is set to the name of the terminal
+- on standard input. If standard input is not a terminal `login'
+- uses standard output or standard error output to determine the
+- name of the terminal. If `struct utmp' has a `ut_type' member,
+- `login' sets it to `USER_PROCESS', and if there is an `ut_pid'
+- member, it will be set to the process ID of the current process.
+- The remaining entries are copied from ENTRY.
+-
+- A copy of the entry is written to the user accounting log file.
+-
+- - Function: int logout (const char *UT_LINE)
+- This function modifies the user accounting database to indicate
+- that the user on UT_LINE has logged out.
+-
+- The `logout' function returns `1' if the entry was successfully
+- written to the database, or `0' on error.
+-
+- - Function: void logwtmp (const char *UT_LINE, const char *UT_NAME,
+- const char *UT_HOST)
+- The `logwtmp' function appends an entry to the user accounting log
+- file, for the current time and the information provided in the
+- UT_LINE, UT_NAME and UT_HOST arguments.
+-
+- *Portability Note:* The BSD `struct utmp' only has the `ut_line',
+-`ut_name', `ut_host' and `ut_time' members. Older systems do not even
+-have the `ut_host' member.

+-
+-Looking Up One User
+--------------------
+-
+- You can search the system user database for information about a
+-specific user using `getpwuid' or `getpwnam'. These functions are
+-declared in `pwd.h'.
+-
+- - Function: struct passwd * getpwuid (uid_t UID)
+- This function returns a pointer to a statically-allocated structure
+- containing information about the user whose user ID is UID. This
+- structure may be overwritten on subsequent calls to `getpwuid'.
+-
+- A null pointer value indicates there is no user in the data base
+- with user ID UID.
+-
+- - Function: int getpwuid_r (uid_t UID, struct passwd *RESULT_BUF, char
+- *BUFFER, size_t BUFLEN, struct passwd **RESULT)
+- This function is similar to `getpwuid' in that it returns
+- information about the user whose user ID is UID. However, it
+- fills the user supplied structure pointed to by RESULT_BUF with
+- the information instead of using a static buffer. The first
+- BUFLEN bytes of the additional buffer pointed to by BUFFER are
+- used to contain additional information, normally strings which are
+- pointed to by the elements of the result structure.
+-
+- If a user with ID UID is found, the pointer returned in RESULT
+- points to the record which contains the wanted data (i.e., RESULT
+- contains the value RESULT_BUF). If no user is found or if an
+- error occurred, the pointer returned in RESULT is a null pointer.
+- The function returns zero or an error code. If the buffer BUFFER
+- is too small to contain all the needed information, the error code
+- `ERANGE' is returned and ERRNO is set to `ERANGE'.
+-
+- - Function: struct passwd * getpwnam (const char *NAME)
+- This function returns a pointer to a statically-allocated structure
+- containing information about the user whose user name is NAME.
+- This structure may be overwritten on subsequent calls to
+- `getpwnam'.
+-
+- A null pointer return indicates there is no user named NAME.
+-
+- - Function: int getpwnam_r (const char *NAME, struct passwd
+- *RESULT_BUF, char *BUFFER, size_t BUFLEN, struct passwd
+- **RESULT)
+- This function is similar to `getpwnam' in that is returns
+- information about the user whose user name is NAME. However, like
+- `getpwuid_r', it fills the user supplied buffers in RESULT_BUF and
+- BUFFER with the information instead of using a static buffer.
+-
+- The return values are the same as for `getpwuid_r'.

+-
+-Scanning the List of All Users
+-------------------------------
+-
+- This section explains how a program can read the list of all users in
+-the system, one user at a time. The functions described here are
+-declared in `pwd.h'.
+-
+- You can use the `fgetpwent' function to read user entries from a
+-particular file.
+-
+- - Function: struct passwd * fgetpwent (FILE *STREAM)
+- This function reads the next user entry from STREAM and returns a
+- pointer to the entry. The structure is statically allocated and is
+- rewritten on subsequent calls to `fgetpwent'. You must copy the
+- contents of the structure if you wish to save the information.
+-
+- The stream must correspond to a file in the same format as the
+- standard password database file.
+-
+- - Function: int fgetpwent_r (FILE *STREAM, struct passwd *RESULT_BUF,
+- char *BUFFER, size_t BUFLEN, struct passwd **RESULT)
+- This function is similar to `fgetpwent' in that it reads the next
+- user entry from STREAM. But the result is returned in the
+- structure pointed to by RESULT_BUF. The first BUFLEN bytes of the
+- additional buffer pointed to by BUFFER are used to contain
+- additional information, normally strings which are pointed to by
+- the elements of the result structure.
+-
+- The stream must correspond to a file in the same format as the
+- standard password database file.
+-
+- If the function returns zero RESULT points to the structure with
+- the wanted data (normally this is in RESULT_BUF). If errors
+- occurred the return value is nonzero and RESULT contains a null
+- pointer.
+-
+- The way to scan all the entries in the user database is with
+-`setpwent', `getpwent', and `endpwent'.
+-
+- - Function: void setpwent (void)
+- This function initializes a stream which `getpwent' and
+- `getpwent_r' use to read the user database.
+-
+- - Function: struct passwd * getpwent (void)
+- The `getpwent' function reads the next entry from the stream
+- initialized by `setpwent'. It returns a pointer to the entry. The
+- structure is statically allocated and is rewritten on subsequent
+- calls to `getpwent'. You must copy the contents of the structure
+- if you wish to save the information.
+-
+- A null pointer is returned when no more entries are available.

+-
+-The Data Structure for a Group
+-------------------------------
+-
+- The functions and data structures for accessing the system group
+-database are declared in the header file `grp.h'.
+-
+- - Data Type: struct group
+- The `group' structure is used to hold information about an entry in
+- the system group database. It has at least the following members:
+-
+- `char *gr_name'
+- The name of the group.
+-
+- `gid_t gr_gid'
+- The group ID of the group.
+-
+- `char **gr_mem'
+- A vector of pointers to the names of users in the group.
+- Each user name is a null-terminated string, and the vector
+- itself is terminated by a null pointer.
+-
+-\1f
+-File: libc.info, Node: Lookup Group, Next: Scanning All Groups, Prev: Group Data Structure, Up: Group Database
+-
+-Looking Up One Group
+---------------------
+-
+- You can search the group database for information about a specific
+-group using `getgrgid' or `getgrnam'. These functions are declared in
+-`grp.h'.
+-
+- - Function: struct group * getgrgid (gid_t GID)
+- This function returns a pointer to a statically-allocated structure
+- containing information about the group whose group ID is GID.
+- This structure may be overwritten by subsequent calls to
+- `getgrgid'.
+-
+- A null pointer indicates there is no group with ID GID.
+-
+- - Function: int getgrgid_r (gid_t GID, struct group *RESULT_BUF, char
+- *BUFFER, size_t BUFLEN, struct group **RESULT)
+- This function is similar to `getgrgid' in that it returns
+- information about the group whose group ID is GID. However, it
+- fills the user supplied structure pointed to by RESULT_BUF with
+- the information instead of using a static buffer. The first
+- BUFLEN bytes of the additional buffer pointed to by BUFFER are
+- used to contain additional information, normally strings which are
+- pointed to by the elements of the result structure.
+-
+- If a group with ID GID is found, the pointer returned in RESULT
+- points to the record which contains the wanted data (i.e., RESULT
+- contains the value RESULT_BUF). If no group is found or if an
+- error occurred, the pointer returned in RESULT is a null pointer.
+- The function returns zero or an error code. If the buffer BUFFER
+- is too small to contain all the needed information, the error code
+- `ERANGE' is returned and ERRNO is set to `ERANGE'.
+-
+- - Function: struct group * getgrnam (const char *NAME)
+- This function returns a pointer to a statically-allocated structure
+- containing information about the group whose group name is NAME.
+- This structure may be overwritten by subsequent calls to
+- `getgrnam'.
+-
+- A null pointer indicates there is no group named NAME.
+-
+- - Function: int getgrnam_r (const char *NAME, struct group
+- *RESULT_BUF, char *BUFFER, size_t BUFLEN, struct group
+- **RESULT)
+- This function is similar to `getgrnam' in that is returns
+- information about the group whose group name is NAME. Like
+- `getgrgid_r', it uses the user supplied buffers in RESULT_BUF and
+- BUFFER, not a static buffer.
+-
+- The return values are the same as for `getgrgid_r' `ERANGE'.

+-
+-Scanning the List of All Groups
+--------------------------------
+-
+- This section explains how a program can read the list of all groups
+-in the system, one group at a time. The functions described here are
+-declared in `grp.h'.
+-
+- You can use the `fgetgrent' function to read group entries from a
+-particular file.
+-
+- - Function: struct group * fgetgrent (FILE *STREAM)
+- The `fgetgrent' function reads the next entry from STREAM. It
+- returns a pointer to the entry. The structure is statically
+- allocated and is overwritten on subsequent calls to `fgetgrent'.
+- You must copy the contents of the structure if you wish to save the
+- information.
+-
+- The stream must correspond to a file in the same format as the
+- standard group database file.
+-
+- - Function: int fgetgrent_r (FILE *STREAM, struct group *RESULT_BUF,
+- char *BUFFER, size_t BUFLEN, struct group **RESULT)
+- This function is similar to `fgetgrent' in that it reads the next
+- user entry from STREAM. But the result is returned in the
+- structure pointed to by RESULT_BUF. The first BUFLEN bytes of the
+- additional buffer pointed to by BUFFER are used to contain
+- additional information, normally strings which are pointed to by
+- the elements of the result structure.
+-
+- This stream must correspond to a file in the same format as the
+- standard group database file.
+-
+- If the function returns zero RESULT points to the structure with
+- the wanted data (normally this is in RESULT_BUF). If errors
+- occurred the return value is non-zero and RESULT contains a null
+- pointer.
+-
+- The way to scan all the entries in the group database is with
+-`setgrent', `getgrent', and `endgrent'.
+-
+- - Function: void setgrent (void)
+- This function initializes a stream for reading from the group data
+- base. You use this stream by calling `getgrent' or `getgrent_r'.
+-
+- - Function: struct group * getgrent (void)
+- The `getgrent' function reads the next entry from the stream
+- initialized by `setgrent'. It returns a pointer to the entry. The
+- structure is statically allocated and is overwritten on subsequent
+- calls to `getgrent'. You must copy the contents of the structure
+- if you wish to save the information.
+-
+- - Function: int getgrent_r (struct group *RESULT_BUF, char *BUFFER,
+- size_t BUFLEN, struct group **RESULT)
+- This function is similar to `getgrent' in that it returns the next
+- entry from the stream initialized by `setgrent'. Like
+- `fgetgrent_r', it places the result in user-supplied buffers
+- pointed to RESULT_BUF and BUFFER.
+-
+- If the function returns zero RESULT contains a pointer to the data
+- (normally equal to RESULT_BUF). If errors occurred the return
+- value is non-zero and RESULT contains a null pointer.
+-
+- - Function: void endgrent (void)
+- This function closes the internal stream used by `getgrent' or
+- `getgrent_r'.

+-Netgroup Data
+--------------
+-
+- Sometimes it is useful to group users according to other criteria
+-(*note Group Database::). E.g., it is useful to associate a certain
+-group of users with a certain machine. On the other hand grouping of
+-host names is not supported so far.
+-
+- In Sun Microsystems SunOS appeared a new kind of database, the
+-netgroup database. It allows grouping hosts, users, and domains
+-freely, giving them individual names. To be more concrete, a netgroup
+-is a list of triples consisting of a host name, a user name, and a
+-domain name where any of the entries can be a wildcard entry matching
+-all inputs. A last possibility is that names of other netgroups can
+-also be given in the list specifying a netgroup. So one can construct
+-arbitrary hierarchies without loops.
+-
+- Sun's implementation allows netgroups only for the `nis' or
+-`nisplus' service, *note Services in the NSS configuration::. The
+-implementation in the GNU C library has no such restriction. An entry
+-in either of the input services must have the following form:
+-
+- GROUPNAME ( GROUPNAME | `('HOSTNAME`,'USERNAME`,'`domainname'`)' )+
+-
+- Any of the fields in the triple can be empty which means anything
+-matches. While describing the functions we will see that the opposite
+-case is useful as well. I.e., there may be entries which will not
+-match any input. For entries like this, a name consisting of the single
+-character `-' shall be used.
+-
+-\1f
+-File: libc.info, Node: Lookup Netgroup, Next: Netgroup Membership, Prev: Netgroup Data, Up: Netgroup Database
+-
+-Looking up one Netgroup
+------------------------
+-
+- The lookup functions for netgroups are a bit different to all other
+-system database handling functions. Since a single netgroup can contain
+-many entries a two-step process is needed. First a single netgroup is
+-selected and then one can iterate over all entries in this netgroup.
+-These functions are declared in `netdb.h'.
+-
+- - Function: int setnetgrent (const char *NETGROUP)
+- A call to this function initializes the internal state of the
+- library to allow following calls of the `getnetgrent' to iterate
+- over all entries in the netgroup with name NETGROUP.
+-
+- When the call is successful (i.e., when a netgroup with this name
+- exists) the return value is `1'. When the return value is `0' no
+- netgroup of this name is known or some other error occurred.
+-
+- It is important to remember that there is only one single state for
+-iterating the netgroups. Even if the programmer uses the
+-`getnetgrent_r' function the result is not really reentrant since
+-always only one single netgroup at a time can be processed. If the
+-program needs to process more than one netgroup simultaneously she must
+-protect this by using external locking. This problem was introduced in
+-the original netgroups implementation in SunOS and since we must stay
+-compatible it is not possible to change this.
+-
+- Some other functions also use the netgroups state. Currently these
+-are the `innetgr' function and parts of the implementation of the
+-`compat' service part of the NSS implementation.
+-
+- - Function: int getnetgrent (char **HOSTP, char **USERP, char
+- **DOMAINP)
+- This function returns the next unprocessed entry of the currently
+- selected netgroup. The string pointers, in which addresses are
+- passed in the arguments HOSTP, USERP, and DOMAINP, will contain
+- after a successful call pointers to appropriate strings. If the
+- string in the next entry is empty the pointer has the value `NULL'.
+- The returned string pointers are only valid if none of the netgroup
+- related functions are called.
+-
+- The return value is `1' if the next entry was successfully read. A
+- value of `0' means no further entries exist or internal errors
+- occurred.
+-
+- - Function: int getnetgrent_r (char **HOSTP, char **USERP, char
+- **DOMAINP, char *BUFFER, int BUFLEN)
+- This function is similar to `getnetgrent' with only one exception:
+- the strings the three string pointers HOSTP, USERP, and DOMAINP
+- point to, are placed in the buffer of BUFLEN bytes starting at
+- BUFFER. This means the returned values are valid even after other
+- netgroup related functions are called.
+-
+- The return value is `1' if the next entry was successfully read and
+- the buffer contains enough room to place the strings in it. `0' is
+- returned in case no more entries are found, the buffer is too
+- small, or internal errors occurred.
+-
+- This function is a GNU extension. The original implementation in
+- the SunOS libc does not provide this function.
+-
+- - Function: void endnetgrent (void)
+- This function frees all buffers which were allocated to process
+- the last selected netgroup. As a result all string pointers
+- returned by calls to `getnetgrent' are invalid afterwards.

+-
+-Testing for Netgroup Membership
+--------------------------------
+-
+- It is often not necessary to scan the whole netgroup since often the
+-only interesting question is whether a given entry is part of the
+-selected netgroup.
+-
+- - Function: int innetgr (const char *NETGROUP, const char *HOST, const
+- char *USER, const char *DOMAIN)
+- This function tests whether the triple specified by the parameters
+- HOSTP, USERP, and DOMAINP is part of the netgroup NETGROUP. Using
+- this function has the advantage that
+-
+- 1. no other netgroup function can use the global netgroup state
+- since internal locking is used and
+-
+- 2. the function is implemented more efficiently than successive
+- calls to the other `set'/`get'/`endnetgrent' functions.
+-
+- Any of the pointers HOSTP, USERP, and DOMAINP can be `NULL' which
+- means any value is accepted in this position. This is also true
+- for the name `-' which should not match any other string otherwise.
+-
+- The return value is `1' if an entry matching the given triple is
+- found in the netgroup. The return value is `0' if the netgroup
+- itself is not found, the netgroup does not contain the triple or
+- internal errors occurred.

+-
+-Host Identification
+-===================
+-
+- This section explains how to identify the particular system on which
+-your program is running. First, let's review the various ways computer
+-systems are named, which is a little complicated because of the history
+-of the development of the Internet.
+-
+- Every Unix system (also known as a host) has a host name, whether
+-it's connected to a network or not. In its simplest form, as used
+-before computer networks were an issue, it's just a word like `chicken'.
+-
+- But any system attached to the Internet or any network like it
+-conforms to a more rigorous naming convention as part of the Domain
+-Name System (DNS). In DNS, every host name is composed of two parts:
+-
+- 1. hostname
+-
+- 2. domain name
+-
+- You will note that "hostname" looks a lot like "host name", but is
+-not the same thing, and that people often incorrectly refer to entire
+-host names as "domain names."
+-
+- In DNS, the full host name is properly called the FQDN (Fully
+-Qualified Domain Name) and consists of the hostname, then a period,
+-then the domain name. The domain name itself usually has multiple
+-components separated by periods. So for example, a system's hostname
+-may be `chicken' and its domain name might be `ai.mit.edu', so its FQDN
+-(which is its host name) is `chicken.ai.mit.edu'.
+-
+- Adding to the confusion, though, is that DNS is not the only name
+-space in which a computer needs to be known. Another name space is the
+-NIS (aka YP) name space. For NIS purposes, there is another domain
+-name, which is called the NIS domain name or the YP domain name. It
+-need not have anything to do with the DNS domain name.
+-
+- Confusing things even more is the fact that in DNS, it is possible
+-for multiple FQDNs to refer to the same system. However, there is
+-always exactly one of them that is the true host name, and it is called
+-the canonical FQDN.
+-
+- In some contexts, the host name is called a "node name."
+-
+- For more information on DNS host naming, *Note Host Names::.
+-
+- Prototypes for these functions appear in `unistd.h'.
+-
+- The programs `hostname', `hostid', and `domainname' work by calling
+-these functions.
+-
+- - Function: int gethostname (char *NAME, size_t SIZE)
+- This function returns the host name of the system on which it is
+- called, in the array NAME. The SIZE argument specifies the size of
+- this array, in bytes. Note that this is _not_ the DNS hostname.
+- If the system participates in DNS, this is the FQDN (see above).
+-
+- The return value is `0' on success and `-1' on failure. In the
+- GNU C library, `gethostname' fails if SIZE is not large enough;
+- then you can try again with a larger array. The following `errno'
+- error condition is defined for this function:
+-
+- `ENAMETOOLONG'
+- The SIZE argument is less than the size of the host name plus
+- one.
+-
+- On some systems, there is a symbol for the maximum possible host
+- name length: `MAXHOSTNAMELEN'. It is defined in `sys/param.h'.
+- But you can't count on this to exist, so it is cleaner to handle
+- failure and try again.
+-
+- `gethostname' stores the beginning of the host name in NAME even
+- if the host name won't entirely fit. For some purposes, a
+- truncated host name is good enough. If it is, you can ignore the
+- error code.
+-
+- - Function: int sethostname (const char *NAME, size_t LENGTH)
+- The `sethostname' function sets the host name of the system that
+- calls it to NAME, a string with length LENGTH. Only privileged
+- processes are permitted to do this.
+-
+- Usually `sethostname' gets called just once, at system boot time.
+- Often, the program that calls it sets it to the value it finds in
+- the file `/etc/hostname'.
+-
+- Be sure to set the host name to the full host name, not just the
+- DNS hostname (see above).
+-
+- The return value is `0' on success and `-1' on failure. The
+- following `errno' error condition is defined for this function:
+-
+- `EPERM'
+- This process cannot set the host name because it is not
+- privileged.
+-
+- - Function: int getdomainnname (char *NAME, size_t LENGTH)
+- `getdomainname' returns the NIS (aka YP) domain name of the system
+- on which it is called. Note that this is not the more popular DNS
+- domain name. Get that with `gethostname'.
+-
+- The specifics of this function are analogous to `gethostname',
+- above.
+-
+-
+- - Function: int setdomainname (const char *NAME, size_t LENGTH)
+- `getdomainname' sets the NIS (aka YP) domain name of the system on
+- which it is called. Note that this is not the more popular DNS
+- domain name. Set that with `sethostname'.
+-
+- The specifics of this function are analogous to `sethostname',
+- above.
+-
+-
+- - Function: long int gethostid (void)
+- This function returns the "host ID" of the machine the program is
+- running on. By convention, this is usually the primary Internet
+- IP address of that machine, converted to a `long int'. However,
+- on some systems it is a meaningless but unique number which is
+- hard-coded for each machine.
+-
+- This is not widely used. It arose in BSD 4.2, but was dropped in
+- BSD 4.4. It is not required by POSIX.
+-
+- The proper way to query the IP address is to use `gethostbyname'
+- on the results of `gethostname'. For more information on IP
+- addresses, *Note Host Addresses::.
+-
+- - Function: int sethostid (long int ID)
+- The `sethostid' function sets the "host ID" of the host machine to
+- ID. Only privileged processes are permitted to do this. Usually
+- it happens just once, at system boot time.
+-
+- The proper way to establish the primary IP address of a system is
+- to configure the IP address resolver to associate that IP address
+- with the system's host name as returned by `gethostname'. For
+- example, put a record for the system in `/etc/hosts'.
+-
+- See `gethostid' above for more information on host ids.
+-
+- The return value is `0' on success and `-1' on failure. The
+- following `errno' error conditions are defined for this function:
+-
+- `EPERM'
+- This process cannot set the host name because it is not
+- privileged.
+-
+- `ENOSYS'
+- The operating system does not support setting the host ID.
+- On some systems, the host ID is a meaningless but unique
+- number hard-coded for each machine.

+-
+-Platform Type Identification
+-============================
+-
+- You can use the `uname' function to find out some information about
+-the type of computer your program is running on. This function and the
+-associated data type are declared in the header file `sys/utsname.h'.
+-
+- As a bonus, `uname' also gives some information identifying the
+-particular system your program is running on. This is the same
+-information which you can get with functions targetted to this purpose
+-described in *Note Host Identification::.
+-
+- - Data Type: struct utsname
+- The `utsname' structure is used to hold information returned by
+- the `uname' function. It has the following members:
+-
+- `char sysname[]'
+- This is the name of the operating system in use.
+-
+- `char release[]'
+- This is the current release level of the operating system
+- implementation.
+-
+- `char version[]'
+- This is the current version level within the release of the
+- operating system.
+-
+- `char machine[]'
+- This is a description of the type of hardware that is in use.
+-
+- Some systems provide a mechanism to interrogate the kernel
+- directly for this information. On systems without such a
+- mechanism, the GNU C library fills in this field based on the
+- configuration name that was specified when building and
+- installing the library.
+-
+- GNU uses a three-part name to describe a system
+- configuration; the three parts are CPU, MANUFACTURER and
+- SYSTEM-TYPE, and they are separated with dashes. Any
+- possible combination of three names is potentially
+- meaningful, but most such combinations are meaningless in
+- practice and even the meaningful ones are not necessarily
+- supported by any particular GNU program.
+-
+- Since the value in `machine' is supposed to describe just the
+- hardware, it consists of the first two parts of the
+- configuration name: `CPU-MANUFACTURER'. For example, it
+- might be one of these:
+-
+- `"sparc-sun"', `"i386-ANYTHING"', `"m68k-hp"',
+- `"m68k-sony"', `"m68k-sun"', `"mips-dec"'
+-
+- `char nodename[]'
+- This is the host name of this particular computer. In the
+- GNU C library, the value is the same as that returned by
+- `gethostname'; see *Note Host Identification::.
+-
+- gethostname() is implemented with a call to uname().
+-
+- `char domainname[]'
+- This is the NIS or YP domain name. It is the same value
+- returned by `getdomainname'; see *Note Host Identification::.
+- This element is a relatively recent invention and use of it
+- is not as portable as use of the rest of the structure.
+-
+-
+- - Function: int uname (struct utsname *INFO)
+- The `uname' function fills in the structure pointed to by INFO
+- with information about the operating system and host machine. A
+- non-negative value indicates that the data was successfully stored.
+-
+- `-1' as the value indicates an error. The only error possible is
+- `EFAULT', which we normally don't mention as it is always a
+- possibility.

+-
+-Controlling and Querying Mounts
+-===============================
+-
+- All files are in filesystems, and before you can access any file, its
+-filesystem must be mounted. Because of Unix's concept of _Everything
+-is a file_, mounting of filesystems is central to doing almost
+-anything. This section explains how to find out what filesystems are
+-currently mounted and what filesystems are available for mounting, and
+-how to change what is mounted.
+-
+- The classic filesystem is the contents of a disk drive. The concept
+-is considerably more abstract, though, and lots of things other than
+-disk drives can be mounted.
+-
+- Some block devices don't correspond to traditional devices like disk
+-drives. For example, a loop device is a block device whose driver uses
+-a regular file in another filesystem as its medium. So if that regular
+-file contains appropriate data for a filesystem, you can by mounting the
+-loop device essentially mount a regular file.
+-
+- Some filesystems aren't based on a device of any kind. The "proc"

+-
+-Mount Information
+------------------
+-
+- For some programs it is desirable and necessary to access information
+-about whether a certain filesystem is mounted and, if it is, where, or
+-simply to get lists of all the available filesystems. The GNU libc
+-provides some functions to retrieve this information portably.
+-
+- Traditionally Unix systems have a file named `/etc/fstab' which
+-describes all possibly mounted filesystems. The `mount' program uses
+-this file to mount at startup time of the system all the necessary
+-filesystems. The information about all the filesystems actually
+-mounted is normally kept in a file named either `/var/run/mtab' or
+-`/etc/mtab'. Both files share the same syntax and it is crucial that
+-this syntax is followed all the time. Therefore it is best to never
+-directly write the files. The functions described in this section can
+-do this and they also provide the functionality to convert the external
+-textual representation to the internal representation.
+-
+- Note that the `fstab' and `mtab' files are maintained on a system by
+-_convention_. It is possible for the files not to exist or not to be
+-consistent with what is really mounted or available to mount, if the
+-system's administration policy allows it. But programs that mount and
+-unmount filesystems typically maintain and use these files as described
+-herein.
+-
+- The filenames given above should never be used directly. The
+-portable way to handle these file is to use the macro `_PATH_FSTAB',
+-defined in `fstab.h', or `_PATH_MNTTAB', defined in `mntent.h' and
+-`paths.h', for `fstab'; and the macro `_PATH_MOUNTED', also defined in
+-`mntent.h' and `paths.h', for `mtab'. There are also two alternate
+-macro names `FSTAB', `MNTTAB', and `MOUNTED' defined but these names
+-are deprecated and kept only for backward compatibility. The names
+-`_PATH_MNTTAB' and `_PATH_MOUNTED' should always be used.

+-
+-The `fstab' file
+-................
+-
+- The internal representation for entries of the file is
+-`struct fstab', defined in `fstab.h'.
+-
+- - Data Type: struct fstab
+- This structure is used with the `getfsent', `getfsspec', and
+- `getfsfile' functions.
+-
+- `char *fs_spec'
+- This element describes the device from which the filesystem
+- is mounted. Normally this is the name of a special device,
+- such as a hard disk partition, but it could also be a more or
+- less generic string. For "NFS" it would be a hostname and
+- directory name combination.
+-
+- Even though the element is not declared `const' it shouldn't
+- be modified. The missing `const' has historic reasons, since
+- this function predates ISO C. The same is true for the other
+- string elements of this structure.
+-
+- `char *fs_file'
+- This describes the mount point on the local system. I.e.,
+- accessing any file in this filesystem has implicitly or
+- explicitly this string as a prefix.
+-
+- `char *fs_vfstype'
+- This is the type of the filesystem. Depending on what the
+- underlying kernel understands it can be any string.
+-
+- `char *fs_mntops'
+- This is a string containing options passed to the kernel with
+- the `mount' call. Again, this can be almost anything. There
+- can be more than one option, separated from the others by a
+- comma. Each option consists of a name and an optional value
+- part, introduced by an `=' character.
+-
+- If the value of this element must be processed it should
+- ideally be done using the `getsubopt' function; see *Note
+- Suboptions::.
+-
+- `const char *fs_type'
+- This name is poorly chosen. This element points to a string
+- (possibly in the `fs_mntops' string) which describes the
+- modes with which the filesystem is mounted. `fstab' defines
+- five macros to describe the possible values:
+-
+- `FSTAB_RW'
+- The filesystems gets mounted with read and write enabled.
+-
+- `FSTAB_RQ'
+- The filesystems gets mounted with read and write
+- enabled. Write access is restricted by quotas.
+-
+- `FSTAB_RO'
+- The filesystem gets mounted read-only.
+-
+- `FSTAB_SW'
+- This is not a real filesystem, it is a swap device.
+-
+- `FSTAB_XX'
+- This entry from the `fstab' file is totally ignored.
+-
+- Testing for equality with these value must happen using
+- `strcmp' since these are all strings. Comparing the pointer
+- will probably always fail.
+-
+- `int fs_freq'
+- This element describes the dump frequency in days.
+-
+- `int fs_passno'
+- This element describes the pass number on parallel dumps. It
+- is closely related to the `dump' utility used on Unix systems.
+-
+- To read the entire content of the of the `fstab' file the GNU libc
+-contains a set of three functions which are designed in the usual way.
+-
+- - Function: int setfsent (void)
+- This function makes sure that the internal read pointer for the
+- `fstab' file is at the beginning of the file. This is done by
+- either opening the file or resetting the read pointer.
+-
+- Since the file handle is internal to the libc this function is not
+- thread-safe.
+-
+- This function returns a non-zero value if the operation was
+- successful and the `getfs*' functions can be used to read the
+- entries of the file.
+-
+- - Function: void endfsent (void)
+- This function makes sure that all resources acquired by a prior
+- call to `setfsent' (explicitly or implicitly by calling
+- `getfsent') are freed.
+-
+- - Function: struct fstab * getfsent (void)
+- This function returns the next entry of the `fstab' file. If this
+- is the first call to any of the functions handling `fstab' since
+- program start or the last call of `endfsent', the file will be
+- opened.
+-
+- The function returns a pointer to a variable of type `struct
+- fstab'. This variable is shared by all threads and therefore this
+- function is not thread-safe. If an error occurred `getfsent'
+- returns a `NULL' pointer.
+-
+- - Function: struct fstab * getfsspec (const char *NAME)
+- This function returns the next entry of the `fstab' file which has
+- a string equal to NAME pointed to by the `fs_spec' element. Since
+- there is normally exactly one entry for each special device it
+- makes no sense to call this function more than once for the same
+- argument. If this is the first call to any of the functions
+- handling `fstab' since program start or the last call of
+- `endfsent', the file will be opened.
+-
+- The function returns a pointer to a variable of type `struct
+- fstab'. This variable is shared by all threads and therefore this
+- function is not thread-safe. If an error occurred `getfsent'
+- returns a `NULL' pointer.
+-
+- - Function: struct fstab * getfsfile (const char *NAME)
+- This function returns the next entry of the `fstab' file which has
+- a string equal to NAME pointed to by the `fs_file' element. Since
+- there is normally exactly one entry for each mount point it makes
+- no sense to call this function more than once for the same
+- argument. If this is the first call to any of the functions
+- handling `fstab' since program start or the last call of
+- `endfsent', the file will be opened.
+-
+- The function returns a pointer to a variable of type `struct
+- fstab'. This variable is shared by all threads and therefore this
+- function is not thread-safe. If an error occurred `getfsent'
+- returns a `NULL' pointer.

+-
+-The `mtab' file
+-...............
+-
+- The following functions and data structure access the `mtab' file.
+-
+- - Data Type: struct mntent
+- This structure is used with the `getmntent', `getmntent_t',
+- `addmntent', and `hasmntopt' functions.
+-
+- `char *mnt_fsname'
+- This element contains a pointer to a string describing the
+- name of the special device from which the filesystem is
+- mounted. It corresponds to the `fs_spec' element in `struct
+- fstab'.
+-
+- `char *mnt_dir'
+- This element points to a string describing the mount point of
+- the filesystem. It corresponds to the `fs_file' element in
+- `struct fstab'.
+-
+- `char *mnt_type'
+- `mnt_type' describes the filesystem type and is therefore
+- equivalent to `fs_vfstype' in `struct fstab'. `mntent.h'
+- defines a few symbolic names for some of the values this
+- string can have. But since the kernel can support arbitrary
+- filesystems it does not make much sense to give them symbolic
+- names. If one knows the symbol name one also knows the
+- filesystem name. Nevertheless here follows the list of the
+- symbols provided in `mntent.h'.
+-
+- `MNTTYPE_IGNORE'
+- This symbol expands to `"ignore"'. The value is
+- sometime used in `fstab' files to make sure entries are
+- not used without removing them.
+-
+- `MNTTYPE_NFS'
+- Expands to `"nfs"'. Using this macro sometimes could
+- make sense since it names the default NFS
+- implementation, in case both version 2 and 3 are
+- supported.
+-
+- `MNTTYPE_SWAP'
+- This symbol expands to `"swap"'. It names the special
+- `fstab' entry which names one of the possibly multiple
+- swap partitions.
+-
+- `char *mnt_opts'
+- The element contains a string describing the options used
+- while mounting the filesystem. As for the equivalent element
+- `fs_mntops' of `struct fstab' it is best to use the function
+- `getsubopt' (*note Suboptions::) to access the parts of this
+- string.
+-
+- The `mntent.h' file defines a number of macros with string
+- values which correspond to some of the options understood by
+- the kernel. There might be many more options which are
+- possible so it doesn't make much sense to rely on these
+- macros but to be consistent here is the list:
+-
+- `MNTOPT_DEFAULTS'
+- Expands to `"defaults"'. This option should be used
+- alone since it indicates all values for the customizable
+- values are chosen to be the default.
+-
+- `MNTOPT_RO'
+- Expands to `"ro"'. See the `FSTAB_RO' value, it means
+- the filesystem is mounted read-only.
+-
+- `MNTOPT_RW'
+- Expand to `"rw"'. See the `FSTAB_RW' value, it means the
+- filesystem is mounted with read and write permissions.
+-
+- `MNTOPT_SUID'
+- Expands to `"suid"'. This means that the SUID bit
+- (*note How Change Persona::) is respected when a program
+- from the filesystem is started.
+-
+- `MNTOPT_NOSUID'
+- Expands to `"nosuid"'. This is the opposite of
+- `MNTOPT_SUID', the SUID bit for all files from the
+- filesystem is ignored.
+-
+- `MNTOPT_NOAUTO'
+- Expands to `"noauto"'. At startup time the `mount'
+- program will ignore this entry if it is started with the
+- `-a' option to mount all filesystems mentioned in the
+- `fstab' file.
+-
+- As for the `FSTAB_*' entries introduced above it is important
+- to use `strcmp' to check for equality.
+-
+- `mnt_freq'
+- This elements corresponds to `fs_freq' and also specifies the
+- frequency in days in which dumps are made.
+-
+- `mnt_passno'
+- This element is equivalent to `fs_passno' with the same
+- meaning which is uninteresting for all programs beside `dump'.
+-
+- For accessing the `mtab' file there is again a set of three
+-functions to access all entries in a row. Unlike the functions to
+-handle `fstab' these functions do not access a fixed file and there is
+-even a thread safe variant of the get function. Beside this the GNU
+-libc contains functions to alter the file and test for specific options.
+-
+- - Function: FILE * setmntent (const char *FILE, const char *MODE)
+- The `setmntent' function prepares the file named FILE which must
+- be in the format of a `fstab' and `mtab' file for the upcoming
+- processing through the other functions of the family. The MODE
+- parameter can be chosen in the way the OPENTYPE parameter for
+- `fopen' (*note Opening Streams::) can be chosen. If the file is
+- opened for writing the file is also allowed to be empty.
+-
+- If the file was successfully opened `setmntent' returns a file
+- descriptor for future use. Otherwise the return value is `NULL'
+- and `errno' is set accordingly.
+-
+- - Function: int endmntent (FILE *STREAM)
+- This function takes for the STREAM parameter a file handle which
+- previously was returned from the `setmntent' call. `endmntent'
+- closes the stream and frees all resources.
+-
+- The return value is 1 unless an error occurred in which case it is
+- 0.
+-
+- - Function: struct mntent * getmntent (FILE *STREAM)
+- The `getmntent' function takes as the parameter a file handle
+- previously returned by successful call to `setmntent'. It returns
+- a pointer to a static variable of type `struct mntent' which is
+- filled with the information from the next entry from the file
+- currently read.
+-
+- The file format used prescribes the use of spaces or tab
+- characters to separate the fields. This makes it harder to use
+- name containing one of these characters (e.g., mount points using
+- spaces). Therefore these characters are encoded in the files and
+- the `getmntent' function takes care of the decoding while reading
+- the entries back in. `'\040'' is used to encode a space
+- character, `'\012'' to encode a tab character and `'\\'' to encode
+- a backslash.
+-
+- If there was an error or the end of the file is reached the return
+- value is `NULL'.
+-
+- This function is not thread-safe since all calls to this function
+- return a pointer to the same static variable. `getmntent_r'
+- should be used in situations where multiple threads access the
+- file.
+-
+- - Function: struct mntent * getmntent_r (FILE *STREAM, struct mentent
+- *RESULT, char *BUFFER, int BUFSIZE)
+- The `getmntent_r' function is the reentrant variant of
+- `getmntent'. It also returns the next entry from the file and
+- returns a pointer. The actual variable the values are stored in
+- is not static, though. Instead the function stores the values in
+- the variable pointed to by the RESULT parameter. Additional
+- information (e.g., the strings pointed to by the elements of the
+- result) are kept in the buffer of size BUFSIZE pointed to by
+- BUFFER.
+-
+- Escaped characters (space, tab, backslash) are converted back in
+- the same way as it happens for `getmentent'.
+-
+- The function returns a `NULL' pointer in error cases. Errors
+- could be:
+- * error while reading the file,
+-
+- * end of file reached,
+-
+- * BUFSIZE is too small for reading a complete new entry.
+-
+- - Function: int addmntent (FILE *STREAM, const struct mntent *MNT)
+- The `addmntent' function allows adding a new entry to the file
+- previously opened with `setmntent'. The new entries are always
+- appended. I.e., even if the position of the file descriptor is
+- not at the end of the file this function does not overwrite an
+- existing entry following the current position.
+-
+- The implication of this is that to remove an entry from a file one
+- has to create a new file while leaving out the entry to be removed
+- and after closing the file remove the old one and rename the new
+- file to the chosen name.
+-
+- This function takes care of spaces and tab characters in the names
+- to be written to the file. It converts them and the backslash
+- character into the format describe in the `getmntent' description
+- above.
+-
+- This function returns 0 in case the operation was successful.
+- Otherwise the return value is 1 and `errno' is set appropriately.
+-
+- - Function: char * hasmntopt (const struct mntent *MNT, const char
+- *OPT)
+- This function can be used to check whether the string pointed to
+- by the `mnt_opts' element of the variable pointed to by MNT
+- contains the option OPT. If this is true a pointer to the
+- beginning of the option in the `mnt_opts' element is returned. If
+- no such option exists the function returns `NULL'.
+-
+- This function is useful to test whether a specific option is
+- present but when all options have to be processed one is better
+- off with using the `getsubopt' function to iterate over all
+- options in the string.

+-Other (Non-libc) Sources of Mount Information
+-.............................................
+-
+- On a system with a Linux kernel and the `proc' filesystem, you can
+-get information on currently mounted filesystems from the file `mounts'
+-in the `proc' filesystem. Its format is similar to that of the `mtab'
+-file, but represents what is truly mounted without relying on
+-facilities outside the kernel to keep `mtab' up to date.

+-
+-Mount, Unmount, Remount
+------------------------
+-
+- This section describes the functions for mounting, unmounting, and
+-remounting filesystems.
+-
+- Only the superuser can mount, unmount, or remount a filesystem.
+-
+- These functions do not access the `fstab' and `mtab' files. You
+-should maintain and use these separately. *Note Mount Information::.
+-
+- The symbols in this section are declared in `sys/mount.h'.
+-
+- - Function: int mount (const char *SPECIAL_FILE, const char *DIR,
+- const char *FSTYPE, unsigned long int OPTIONS, const void
+- *DATA)
+- `mount' mounts or remounts a filesystem. The two operations are
+- quite different and are merged rather unnaturally into this one
+- function. The `MS_REMOUNT' option, explained below, determines
+- whether `mount' mounts or remounts.
+-
+- For a mount, the filesystem on the block device represented by the
+- device special file named SPECIAL_FILE gets mounted over the mount
+- point DIR. This means that the directory DIR (along with any
+- files in it) is no longer visible; in its place (and still with
+- the name DIR) is the root directory of the filesystem on the
+- device.
+-
+- As an exception, if the filesystem type (see below) is one which
+- is not based on a device (e.g. "proc"), `mount' instantiates a
+- filesystem and mounts it over DIR and ignores SPECIAL_FILE.
+-
+- For a remount, DIR specifies the mount point where the filesystem
+- to be remounted is (and remains) mounted and SPECIAL_FILE is
+- ignored. Remounting a filesystem means changing the options that
+- control operations on the filesystem while it is mounted. It does
+- not mean unmounting and mounting again.
+-
+- For a mount, you must identify the type of the filesystem as
+- FSTYPE. This type tells the kernel how to access the filesystem
+- and can be thought of as the name of a filesystem driver. The
+- acceptable values are system dependent. On a system with a Linux
+- kernel and the `proc' filesystem, the list of possible values is
+- in the file `filesystems' in the `proc' filesystem (e.g. type `cat
+- /proc/filesystems' to see the list). With a Linux kernel, the
+- types of filesystems that `mount' can mount, and their type names,
+- depends on what filesystem drivers are configured into the kernel
+- or loaded as loadable kernel modules. An example of a common
+- value for FSTYPE is `ext2'.
+-
+- For a remount, `mount' ignores FSTYPE.
+-
+- OPTIONS specifies a variety of options that apply until the
+- filesystem is unmounted or remounted. The precise meaning of an
+- option depends on the filesystem and with some filesystems, an
+- option may have no effect at all. Furthermore, for some
+- filesystems, some of these options (but never `MS_RDONLY') can be
+- overridden for individual file accesses via `ioctl'.
+-
+- OPTIONS is a bit string with bit fields defined using the
+- following mask and masked value macros:
+-
+- `MS_MGC_MASK'
+- This multibit field contains a magic number. If it does not
+- have the value `MS_MGC_VAL', `mount' assumes all the
+- following bits are zero and the DATA argument is a null
+- string, regardless of their actual values.
+-
+- `MS_REMOUNT'
+- This bit on means to remount the filesystem. Off means to
+- mount it.
+-
+- `MS_RDONLY'
+- This bit on specifies that no writing to the filesystem shall
+- be allowed while it is mounted. This cannot be overridden by
+- `ioctl'. This option is available on nearly all filesystems.
+-
+- `S_IMMUTABLE'
+- This bit on specifies that no writing to the files in the
+- filesystem shall be allowed while it is mounted. This can be
+- overridden for a particular file access by a properly
+- privileged call to `ioctl'. This option is a relatively new
+- invention and is not available on many filesystems.
+-
+- `S_APPEND'
+- This bit on specifies that the only file writing that shall
+- be allowed while the filesystem is mounted is appending.
+- Some filesystems allow this to be overridden for a particular
+- process by a properly privileged call to `ioctl'. This is a
+- relatively new invention and is not available on many
+- filesystems.
+-
+- `MS_NOSUID'
+- This bit on specifies that Setuid and Setgid permissions on
+- files in the filesystem shall be ignored while it is mounted.
+-
+- `MS_NOEXEC'
+- This bit on specifies that no files in the filesystem shall
+- be executed while the filesystem is mounted.
+-
+- `MS_NODEV'
+- This bit on specifies that no device special files in the
+- filesystem shall be accessible while the filesystem is
+- mounted.
+-
+- `MS_SYNCHRONOUS'
+- This bit on specifies that all writes to the filesystem while
+- it is mounted shall be synchronous; i.e. data shall be synced
+- before each write completes rather than held in the buffer
+- cache.
+-
+- `MS_MANDLOCK'
+- This bit on specifies that mandatory locks on files shall be
+- permitted while the filesystem is mounted.
+-
+- `MS_NOATIME'
+- This bit on specifies that access times of files shall not be
+- updated when the files are accessed while the filesystem is
+- mounted.
+-
+- `MS_NODIRATIME'
+- This bit on specifies that access times of directories shall
+- not be updated when the directories are accessed while the
+- filesystem in mounted.
+-
+- Any bits not covered by the above masks should be set off;
+- otherwise, results are undefined.
+-
+- The meaning of DATA depends on the filesystem type and is
+- controlled entirely by the filesystem driver in the kernel.
+-
+- Example:
+-
+- #include <sys/mount.h>
+-
+- mount("/dev/hdb", "/cdrom", MS_MGC_VAL | MS_RDONLY | MS_NOSUID, "");
+-
+- mount("/dev/hda2", "/mnt", MS_MGC_VAL | MS_REMOUNT, "");
+-
+- Appropriate arguments for `mount' are conventionally recorded in
+- the `fstab' table. *Note Mount Information::.
+-
+- The return value is zero if the mount or remount is successful.
+- Otherwise, it is `-1' and `errno' is set appropriately. The
+- values of `errno' are filesystem dependent, but here is a general
+- list:
+-
+- `EPERM'
+- The process is not superuser.
+-
+- `ENODEV'
+- The file system type FSTYPE is not known to the kernel.
+-
+- `ENOTBLK'
+- The file DEV is not a block device special file.
+-
+- `EBUSY'
+- * The device is already mounted.
+-
+- * The mount point is busy. (E.g. it is some process'
+- working directory or has a filesystem mounted on it
+- already).
+-
+- * The request is to remount read-only, but there are files
+- open for write.
+-
+- `EINVAL'
+- * A remount was attempted, but there is no filesystem
+- mounted over the specified mount point.
+-
+- * The supposed filesystem has an invalid superblock.
+-
+-
+- `EACCES'
+- * The filesystem is inherently read-only (possibly due to
+- a switch on the device) and the process attempted to
+- mount it read/write (by setting the `MS_RDONLY' bit off).
+-
+- * SPECIAL_FILE or DIR is not accessible due to file
+- permissions.
+-
+- * SPECIAL_FILE is not accessible because it is in a
+- filesystem that is mounted with the `MS_NODEV' option.
+-
+-
+- `EM_FILE'
+- The table of dummy devices is full. `mount' needs to create a
+- dummy device (aka "unnamed" device) if the filesystem being
+- mounted is not one that uses a device.
+-
+-
+- - Function: int umount2 (const char *FILE, int FLAGS)
+- `umount2' unmounts a filesystem.
+-
+- You can identify the filesystem to unmount either by the device
+- special file that contains the filesystem or by the mount point.
+- The effect is the same. Specify either as the string FILE.
+-
+- FLAGS contains the one-bit field identified by the following mask
+- macro:
+-
+- `MNT_FORCE'
+- This bit on means to force the unmounting even if the
+- filesystem is busy, by making it unbusy first. If the bit is
+- off and the filesystem is busy, `umount2' fails with `errno'
+- = `EBUSY'. Depending on the filesystem, this may override
+- all, some, or no busy conditions.
+-
+- All other bits in FLAGS should be set to zero; otherwise, the
+- result is undefined.
+-
+- Example:
+-
+- #include <sys/mount.h>
+-
+- umount2("/mnt", MNT_FORCE);
+-
+- umount2("/dev/hdd1", 0);
+-
+- After the filesystem is unmounted, the directory that was the
+- mount point is visible, as are any files in it.
+-
+- As part of unmounting, `umount2' syncs the filesystem.
+-
+- If the unmounting is successful, the return value is zero.
+- Otherwise, it is `-1' and `errno' is set accordingly:
+-
+- `EPERM'
+- The process is not superuser.
+-
+- `EBUSY'
+- The filesystem cannot be unmounted because it is busy. E.g.
+- it contains a directory that is some process's working
+- directory or a file that some process has open. With some
+- filesystems in some cases, you can avoid this failure with
+- the `MNT_FORCE' option.
+-

+-System Parameters
+-=================
+-
+- This section describes the `sysctl' function, which gets and sets a
+-variety of system parameters.
+-
+- The symbols used in this section are declared in the file `sysctl.h'.
+-
+- - Function: int sysctl (int *NAMES, int NLEN, void *OLDVAL,
+- size_t *OLDLENP, void *NEWVAL, size_t NEWLEN)
+-
+- `sysctl' gets or sets a specified system parameter. There are so
+- many of these parameters that it is not practical to list them all
+- here, but here are some examples:
+-
+- * network domain name
+-
+- * paging parameters
+-
+- * network Address Resolution Protocol timeout time
+-
+- * maximum number of files that may be open
+-
+- * root filesystem device
+-
+- * when kernel was built
+-
+- The set of available parameters depends on the kernel
+- configuration and can change while the system is running,
+- particularly when you load and unload loadable kernel modules.
+-
+- The system parameters with which `syslog' is concerned are arranged
+- in a hierarchical structure like a hierarchical filesystem. To
+- identify a particular parameter, you specify a path through the
+- structure in a way analogous to specifying the pathname of a file.
+- Each component of the path is specified by an integer and each of
+- these integers has a macro defined for it by `sysctl.h'. NAMES is
+- the path, in the form of an array of integers. Each component of
+- the path is one element of the array, in order. NLEN is the
+- number of components in the path.
+-
+- For example, the first component of the path for all the paging
+- parameters is the value `CTL_VM'. For the free page thresholds,
+- the second component of the path is `VM_FREEPG'. So to get the
+- free page threshold values, make NAMES an array containing the two
+- elements `CTL_VM' and `VM_FREEPG' and make NLEN = 2.
+-
+- The format of the value of a parameter depends on the parameter.
+- Sometimes it is an integer; sometimes it is an ASCII string;
+- sometimes it is an elaborate structure. In the case of the free
+- page thresholds used in the example above, the parameter value is
+- a structure containing several integers.
+-
+- In any case, you identify a place to return the parameter's value
+- with OLDVAL and specify the amount of storage available at that
+- location as *OLDLENP. *OLDLENP does double duty because it is
+- also the output location that contains the actual length of the
+- returned value.
+-
+- If you don't want the parameter value returned, specify a null
+- pointer for OLDVAL.
+-
+- To set the parameter, specify the address and length of the new
+- value as NEWVAL and NEWLEN. If you don't want to set the
+- parameter, specify a null pointer as NEWVAL.
+-
+- If you get and set a parameter in the same `sysctl' call, the value
+- returned is the value of the parameter before it was set.
+-
+- Each system parameter has a set of permissions similar to the
+- permissions for a file (including the permissions on directories
+- in its path) that determine whether you may get or set it. For
+- the purposes of these permissions, every parameter is considered
+- to be owned by the superuser and Group 0 so processes with that
+- effective uid or gid may have more access to system parameters.
+- Unlike with files, the superuser does not invariably have full
+- permission to all system parameters, because some of them are
+- designed not to be changed ever.
+-
+- `sysctl' returns a zero return value if it succeeds. Otherwise, it
+- returns `-1' and sets `errno' appropriately. Besides the failures
+- that apply to all system calls, the following are the `errno'
+- codes for all possible failures:
+-
+- `EPERM'
+- The process is not permitted to access one of the components
+- of the path of the system parameter or is not permitted to
+- access the system parameter itself in the way (read or write)
+- that it requested.
+-
+- `ENOTDIR'
+- There is no system parameter corresponding to NAME.
+-
+- `EFAULT'
+- OLDVAL is not null, which means the process wanted to read
+- the parameter, but *OLDLENP is zero, so there is no place to
+- return it.
+-
+- `EINVAL'
+- * The process attempted to set a system parameter to a
+- value that is not valid for that parameter.
+-
+- * The space provided for the return of the system
+- parameter is not the right size for that parameter.
+-
+- `ENOMEM'
+- This value may be returned instead of the more correct
+- `EINVAL' in some cases where the space provided for the
+- return of the system parameter is too small.
+-
+-
+- If you have a Linux kernel with the `proc' filesystem, you can get
+-and set most of the same parameters by reading and writing to files in
+-the `sys' directory of the `proc' filesystem. In the `sys' directory,
+-the directory structure represents the hierarchical structure of the
+-parameters. E.g. you can display the free page thresholds with
+- cat /proc/sys/vm/freepages
+-
+- Some more traditional and more widely available, though less general,
+-GNU C library functions for getting and setting some of the same system
+-parameters are:
+-
+- * `getdomainname', `setdomainname'
+-
+- * `gethostname', `sethostname' (*Note Host Identification::.)
+-
+- * `uname' (*Note Platform Type::.)
+-
+- * `bdflush'

+-General Capacity Limits
+-=======================
+-
+- The POSIX.1 and POSIX.2 standards specify a number of parameters that
+-describe capacity limitations of the system. These limits can be fixed
+-constants for a given operating system, or they can vary from machine to
+-machine. For example, some limit values may be configurable by the
+-system administrator, either at run time or by rebuilding the kernel,
+-and this should not require recompiling application programs.
+-
+- Each of the following limit parameters has a macro that is defined in
+-`limits.h' only if the system has a fixed, uniform limit for the
+-parameter in question. If the system allows different file systems or
+-files to have different limits, then the macro is undefined; use
+-`sysconf' to find out the limit that applies at a particular time on a
+-particular machine. *Note Sysconf::.
+-
+- Each of these parameters also has another macro, with a name starting
+-with `_POSIX', which gives the lowest value that the limit is allowed
+-to have on _any_ POSIX system. *Note Minimums::.
+-
+- - Macro: int ARG_MAX
+- If defined, the unvarying maximum combined length of the ARGV and
+- ENVIRON arguments that can be passed to the `exec' functions.
+-
+- - Macro: int CHILD_MAX
+- If defined, the unvarying maximum number of processes that can
+- exist with the same real user ID at any one time. In BSD and GNU,
+- this is controlled by the `RLIMIT_NPROC' resource limit; *note
+- Limits on Resources::.
+-
+- - Macro: int OPEN_MAX
+- If defined, the unvarying maximum number of files that a single
+- process can have open simultaneously. In BSD and GNU, this is
+- controlled by the `RLIMIT_NOFILE' resource limit; *note Limits on
+- Resources::.
+-
+- - Macro: int STREAM_MAX
+- If defined, the unvarying maximum number of streams that a single
+- process can have open simultaneously. *Note Opening Streams::.
+-
+- - Macro: int TZNAME_MAX
+- If defined, the unvarying maximum length of a time zone name.
+- *Note Time Zone Functions::.
+-
+- These limit macros are always defined in `limits.h'.
+-
+- - Macro: int NGROUPS_MAX
+- The maximum number of supplementary group IDs that one process can
+- have.
+-
+- The value of this macro is actually a lower bound for the maximum.
+- That is, you can count on being able to have that many
+- supplementary group IDs, but a particular machine might let you
+- have even more. You can use `sysconf' to see whether a particular
+- machine will let you have more (*note Sysconf::).
+-
+- - Macro: int SSIZE_MAX
+- The largest value that can fit in an object of type `ssize_t'.
+- Effectively, this is the limit on the number of bytes that can be
+- read or written in a single operation.
+-
+- This macro is defined in all POSIX systems because this limit is
+- never configurable.
+-
+- - Macro: int RE_DUP_MAX
+- The largest number of repetitions you are guaranteed is allowed in
+- the construct `\{MIN,MAX\}' in a regular expression.
+-
+- The value of this macro is actually a lower bound for the maximum.
+- That is, you can count on being able to have that many
+- repetitions, but a particular machine might let you have even
+- more. You can use `sysconf' to see whether a particular machine
+- will let you have more (*note Sysconf::). And even the value that
+- `sysconf' tells you is just a lower bound--larger values might
+- work.
+-
+- This macro is defined in all POSIX.2 systems, because POSIX.2 says
+- it should always be defined even if there is no specific imposed
+- limit.

+-
+-Overall System Options
+-======================
+-
+- POSIX defines certain system-specific options that not all POSIX
+-systems support. Since these options are provided in the kernel, not
+-in the library, simply using the GNU C library does not guarantee any
+-of these features is supported; it depends on the system you are using.
+-
+- You can test for the availability of a given option using the macros
+-in this section, together with the function `sysconf'. The macros are
+-defined only if you include `unistd.h'.
+-
+- For the following macros, if the macro is defined in `unistd.h',
+-then the option is supported. Otherwise, the option may or may not be
+-supported; use `sysconf' to find out. *Note Sysconf::.
+-
+- - Macro: int _POSIX_JOB_CONTROL
+- If this symbol is defined, it indicates that the system supports
+- job control. Otherwise, the implementation behaves as if all
+- processes within a session belong to a single process group.
+- *Note Job Control::.
+-
+- - Macro: int _POSIX_SAVED_IDS
+- If this symbol is defined, it indicates that the system remembers
+- the effective user and group IDs of a process before it executes an
+- executable file with the set-user-ID or set-group-ID bits set, and
+- that explicitly changing the effective user or group IDs back to
+- these values is permitted. If this option is not defined, then if
+- a nonprivileged process changes its effective user or group ID to
+- the real user or group ID of the process, it can't change it back
+- again. *Note Enable/Disable Setuid::.
+-
+- For the following macros, if the macro is defined in `unistd.h',
+-then its value indicates whether the option is supported. A value of
+-`-1' means no, and any other value means yes. If the macro is not
+-defined, then the option may or may not be supported; use `sysconf' to
+-find out. *Note Sysconf::.
+-
+- - Macro: int _POSIX2_C_DEV
+- If this symbol is defined, it indicates that the system has the
+- POSIX.2 C compiler command, `c89'. The GNU C library always
+- defines this as `1', on the assumption that you would not have
+- installed it if you didn't have a C compiler.
+-
+- - Macro: int _POSIX2_FORT_DEV
+- If this symbol is defined, it indicates that the system has the
+- POSIX.2 Fortran compiler command, `fort77'. The GNU C library
+- never defines this, because we don't know what the system has.
+-
+- - Macro: int _POSIX2_FORT_RUN
+- If this symbol is defined, it indicates that the system has the
+- POSIX.2 `asa' command to interpret Fortran carriage control. The
+- GNU C library never defines this, because we don't know what the
+- system has.
+-
+- - Macro: int _POSIX2_LOCALEDEF
+- If this symbol is defined, it indicates that the system has the
+- POSIX.2 `localedef' command. The GNU C library never defines
+- this, because we don't know what the system has.
+-
+- - Macro: int _POSIX2_SW_DEV
+- If this symbol is defined, it indicates that the system has the
+- POSIX.2 commands `ar', `make', and `strip'. The GNU C library
+- always defines this as `1', on the assumption that you had to have
+- `ar' and `make' to install the library, and it's unlikely that
+- `strip' would be absent when those are present.

+-File: libc.info, Node: Version Supported, Next: Sysconf, Prev: System Options, Up: System Configuration
+-
+-Which Version of POSIX is Supported
+-===================================
+-
+- - Macro: long int _POSIX_VERSION
+- This constant represents the version of the POSIX.1 standard to
+- which the implementation conforms. For an implementation
+- conforming to the 1995 POSIX.1 standard, the value is the integer
+- `199506L'.
+-
+- `_POSIX_VERSION' is always defined (in `unistd.h') in any POSIX
+- system.
+-
+- *Usage Note:* Don't try to test whether the system supports POSIX
+- by including `unistd.h' and then checking whether `_POSIX_VERSION'
+- is defined. On a non-POSIX system, this will probably fail
+- because there is no `unistd.h'. We do not know of _any_ way you
+- can reliably test at compilation time whether your target system
+- supports POSIX or whether `unistd.h' exists.
+-
+- The GNU C compiler predefines the symbol `__POSIX__' if the target
+- system is a POSIX system. Provided you do not use any other
+- compilers on POSIX systems, testing `defined (__POSIX__)' will
+- reliably detect such systems.
+-
+- - Macro: long int _POSIX2_C_VERSION
+- This constant represents the version of the POSIX.2 standard which
+- the library and system kernel support. We don't know what value
+- this will be for the first version of the POSIX.2 standard,
+- because the value is based on the year and month in which the
+- standard is officially adopted.
+-
+- The value of this symbol says nothing about the utilities
+- installed on the system.
+-
+- *Usage Note:* You can use this macro to tell whether a POSIX.1
+- system library supports POSIX.2 as well. Any POSIX.1 system
+- contains `unistd.h', so include that file and then test `defined
+- (_POSIX2_C_VERSION)'.

+-Examples of `sysconf'
+----------------------
+-
+- We recommend that you first test for a macro definition for the
+-parameter you are interested in, and call `sysconf' only if the macro
+-is not defined. For example, here is how to test whether job control
+-is supported:
+-
+- int
+- have_job_control (void)
+- {
+- #ifdef _POSIX_JOB_CONTROL
+- return 1;
+- #else
+- int value = sysconf (_SC_JOB_CONTROL);
+- if (value < 0)
+- /* If the system is that badly wedged,
+- there's no use trying to go on. */
+- fatal (strerror (errno));
+- return value;
+- #endif
+- }
+-
+- Here is how to get the value of a numeric limit:
+-
+- int
+- get_child_max ()
+- {
+- #ifdef CHILD_MAX
+- return CHILD_MAX;
+- #else
+- int value = sysconf (_SC_CHILD_MAX);
+- if (value < 0)
+- fatal (strerror (errno));
+- return value;

+-Minimum Values for General Capacity Limits
+-==========================================
+-
+- Here are the names for the POSIX minimum upper bounds for the system
+-limit parameters. The significance of these values is that you can
+-safely push to these limits without checking whether the particular
+-system you are using can go that far.
+-
+-`_POSIX_AIO_LISTIO_MAX'
+- The most restrictive limit permitted by POSIX for the maximum
+- number of I/O operations that can be specified in a list I/O call.
+- The value of this constant is `2'; thus you can add up to two new
+- entries of the list of outstanding operations.
+-
+-`_POSIX_AIO_MAX'
+- The most restrictive limit permitted by POSIX for the maximum
+- number of outstanding asynchronous I/O operations. The value of
+- this constant is `1'. So you cannot expect that you can issue
+- more than one operation and immediately continue with the normal
+- work, receiving the notifications asynchronously.
+-
+-`_POSIX_ARG_MAX'
+- The value of this macro is the most restrictive limit permitted by
+- POSIX for the maximum combined length of the ARGV and ENVIRON
+- arguments that can be passed to the `exec' functions. Its value
+- is `4096'.
+-
+-`_POSIX_CHILD_MAX'
+- The value of this macro is the most restrictive limit permitted by
+- POSIX for the maximum number of simultaneous processes per real
+- user ID. Its value is `6'.
+-
+-`_POSIX_NGROUPS_MAX'
+- The value of this macro is the most restrictive limit permitted by
+- POSIX for the maximum number of supplementary group IDs per
+- process. Its value is `0'.
+-
+-`_POSIX_OPEN_MAX'
+- The value of this macro is the most restrictive limit permitted by
+- POSIX for the maximum number of files that a single process can
+- have open simultaneously. Its value is `16'.
+-
+-`_POSIX_SSIZE_MAX'
+- The value of this macro is the most restrictive limit permitted by
+- POSIX for the maximum value that can be stored in an object of type
+- `ssize_t'. Its value is `32767'.
+-
+-`_POSIX_STREAM_MAX'
+- The value of this macro is the most restrictive limit permitted by
+- POSIX for the maximum number of streams that a single process can
+- have open simultaneously. Its value is `8'.
+-
+-`_POSIX_TZNAME_MAX'
+- The value of this macro is the most restrictive limit permitted by
+- POSIX for the maximum length of a time zone name. Its value is
+- `3'.
+-
+-`_POSIX2_RE_DUP_MAX'
+- The value of this macro is the most restrictive limit permitted by
+- POSIX for the numbers used in the `\{MIN,MAX\}' construct in a
+- regular expression. Its value is `255'.

+-Limits on File System Capacity
+-==============================
+-
+- The POSIX.1 standard specifies a number of parameters that describe
+-the limitations of the file system. It's possible for the system to
+-have a fixed, uniform limit for a parameter, but this isn't the usual
+-case. On most systems, it's possible for different file systems (and,
+-for some parameters, even different files) to have different maximum
+-limits. For example, this is very likely if you use NFS to mount some
+-of the file systems from other machines.
+-
+- Each of the following macros is defined in `limits.h' only if the
+-system has a fixed, uniform limit for the parameter in question. If the
+-system allows different file systems or files to have different limits,
+-then the macro is undefined; use `pathconf' or `fpathconf' to find out
+-the limit that applies to a particular file. *Note Pathconf::.
+-
+- Each parameter also has another macro, with a name starting with
+-`_POSIX', which gives the lowest value that the limit is allowed to
+-have on _any_ POSIX system. *Note File Minimums::.
+-
+- - Macro: int LINK_MAX
+- The uniform system limit (if any) for the number of names for a
+- given file. *Note Hard Links::.
+-
+- - Macro: int MAX_CANON
+- The uniform system limit (if any) for the amount of text in a line
+- of input when input editing is enabled. *Note Canonical or Not::.
+-
+- - Macro: int MAX_INPUT
+- The uniform system limit (if any) for the total number of
+- characters typed ahead as input. *Note I/O Queues::.
+-
+- - Macro: int NAME_MAX
+- The uniform system limit (if any) for the length of a file name
+- component.
+-
+- - Macro: int PATH_MAX
+- The uniform system limit (if any) for the length of an entire file
+- name (that is, the argument given to system calls such as `open').
+-
+- - Macro: int PIPE_BUF
+- The uniform system limit (if any) for the number of bytes that can
+- be written atomically to a pipe. If multiple processes are
+- writing to the same pipe simultaneously, output from different
+- processes might be interleaved in chunks of this size. *Note
+- Pipes and FIFOs::.
+-
+- These are alternative macro names for some of the same information.
+-
+- - Macro: int MAXNAMLEN
+- This is the BSD name for `NAME_MAX'. It is defined in `dirent.h'.
+-
+- - Macro: int FILENAME_MAX
+- The value of this macro is an integer constant expression that
+- represents the maximum length of a file name string. It is
+- defined in `stdio.h'.
+-
+- Unlike `PATH_MAX', this macro is defined even if there is no actual
+- limit imposed. In such a case, its value is typically a very large
+- number. *This is always the case on the GNU system.*
+-
+- *Usage Note:* Don't use `FILENAME_MAX' as the size of an array in
+- which to store a file name! You can't possibly make an array that
+- big! Use dynamic allocation (*note Memory Allocation::) instead.

+-
+-Optional Features in File Support
+-=================================
+-
+- POSIX defines certain system-specific options in the system calls for
+-operating on files. Some systems support these options and others do
+-not. Since these options are provided in the kernel, not in the
+-library, simply using the GNU C library does not guarantee that any of
+-these features is supported; it depends on the system you are using.
+-They can also vary between file systems on a single machine.
+-
+- This section describes the macros you can test to determine whether a
+-particular option is supported on your machine. If a given macro is
+-defined in `unistd.h', then its value says whether the corresponding
+-feature is supported. (A value of `-1' indicates no; any other value
+-indicates yes.) If the macro is undefined, it means particular files
+-may or may not support the feature.
+-
+- Since all the machines that support the GNU C library also support
+-NFS, one can never make a general statement about whether all file
+-systems support the `_POSIX_CHOWN_RESTRICTED' and `_POSIX_NO_TRUNC'
+-features. So these names are never defined as macros in the GNU C
+-library.
+-
+- - Macro: int _POSIX_CHOWN_RESTRICTED
+- If this option is in effect, the `chown' function is restricted so
+- that the only changes permitted to nonprivileged processes is to
+- change the group owner of a file to either be the effective group
+- ID of the process, or one of its supplementary group IDs. *Note
+- File Owner::.
+-
+- - Macro: int _POSIX_NO_TRUNC
+- If this option is in effect, file name components longer than
+- `NAME_MAX' generate an `ENAMETOOLONG' error. Otherwise, file name
+- components that are too long are silently truncated.
+-
+- - Macro: unsigned char _POSIX_VDISABLE
+- This option is only meaningful for files that are terminal devices.
+- If it is enabled, then handling for special control characters can
+- be disabled individually. *Note Special Characters::.
+-
+- If one of these macros is undefined, that means that the option
+-might be in effect for some files and not for others. To inquire about
+-a particular file, call `pathconf' or `fpathconf'. *Note Pathconf::.

+-Minimum Values for File System Limits
+-=====================================
+-
+- Here are the names for the POSIX minimum upper bounds for some of the
+-above parameters. The significance of these values is that you can
+-safely push to these limits without checking whether the particular
+-system you are using can go that far. In most cases GNU systems do not
+-have these strict limitations. The actual limit should be requested if
+-necessary.
+-
+-`_POSIX_LINK_MAX'
+- The most restrictive limit permitted by POSIX for the maximum
+- value of a file's link count. The value of this constant is `8';
+- thus, you can always make up to eight names for a file without
+- running into a system limit.
+-
+-`_POSIX_MAX_CANON'
+- The most restrictive limit permitted by POSIX for the maximum
+- number of bytes in a canonical input line from a terminal device.
+- The value of this constant is `255'.
+-
+-`_POSIX_MAX_INPUT'
+- The most restrictive limit permitted by POSIX for the maximum
+- number of bytes in a terminal device input queue (or typeahead
+- buffer). *Note Input Modes::. The value of this constant is
+- `255'.
+-
+-`_POSIX_NAME_MAX'
+- The most restrictive limit permitted by POSIX for the maximum
+- number of bytes in a file name component. The value of this
+- constant is `14'.
+-
+-`_POSIX_PATH_MAX'
+- The most restrictive limit permitted by POSIX for the maximum
+- number of bytes in a file name. The value of this constant is
+- `256'.
+-
+-`_POSIX_PIPE_BUF'
+- The most restrictive limit permitted by POSIX for the maximum
+- number of bytes that can be written atomically to a pipe. The
+- value of this constant is `512'.
+-
+-`SYMLINK_MAX'
+- Maximum number of bytes in a symbolic link.
+-
+-`POSIX_REC_INCR_XFER_SIZE'
+- Recommended increment for file transfer sizes between the
+- `POSIX_REC_MIN_XFER_SIZE' and `POSIX_REC_MAX_XFER_SIZE' values.
+-
+-`POSIX_REC_MAX_XFER_SIZE'
+- Maximum recommended file transfer size.

+-
+-Using `pathconf'
+-================
+-
+- When your machine allows different files to have different values
+-for a file system parameter, you can use the functions in this section
+-to find out the value that applies to any particular file.
+-
+- These functions and the associated constants for the PARAMETER
+-argument are declared in the header file `unistd.h'.
+-
+- - Function: long int pathconf (const char *FILENAME, int PARAMETER)
+- This function is used to inquire about the limits that apply to
+- the file named FILENAME.
+-
+- The PARAMETER argument should be one of the `_PC_' constants
+- listed below.
+-
+- The normal return value from `pathconf' is the value you requested.
+- A value of `-1' is returned both if the implementation does not
+- impose a limit, and in case of an error. In the former case,
+- `errno' is not set, while in the latter case, `errno' is set to
+- indicate the cause of the problem. So the only way to use this
+- function robustly is to store `0' into `errno' just before calling
+- it.
+-
+- Besides the usual file name errors (*note File Name Errors::), the
+- following error condition is defined for this function:
+-
+- `EINVAL'
+- The value of PARAMETER is invalid, or the implementation
+- doesn't support the PARAMETER for the specific file.
+-
+- - Function: long int fpathconf (int FILEDES, int PARAMETER)
+- This is just like `pathconf' except that an open file descriptor
+- is used to specify the file for which information is requested,
+- instead of a file name.
+-
+- The following `errno' error conditions are defined for this
+- function:
+-
+- `EBADF'
+- The FILEDES argument is not a valid file descriptor.
+-
+- `EINVAL'
+- The value of PARAMETER is invalid, or the implementation
+- doesn't support the PARAMETER for the specific file.
+-
+- Here are the symbolic constants that you can use as the PARAMETER
+-argument to `pathconf' and `fpathconf'. The values are all integer
+-constants.

+- Inquire about the value of `LINK_MAX'.
+-
+-`_PC_MAX_CANON'

+-Utility Program Capacity Limits
+-===============================
+-
+- The POSIX.2 standard specifies certain system limits that you can
+-access through `sysconf' that apply to utility behavior rather than the
+-behavior of the library or the operating system.
+-
+- The GNU C library defines macros for these limits, and `sysconf'
+-returns values for them if you ask; but these values convey no
+-meaningful information. They are simply the smallest values that
+-POSIX.2 permits.
+-
+- - Macro: int BC_BASE_MAX
+- The largest value of `obase' that the `bc' utility is guaranteed
+- to support.
+-
+- - Macro: int BC_DIM_MAX
+- The largest number of elements in one array that the `bc' utility
+- is guaranteed to support.
+-
+- - Macro: int BC_SCALE_MAX
+- The largest value of `scale' that the `bc' utility is guaranteed
+- to support.
+-
+- - Macro: int BC_STRING_MAX
+- The largest number of characters in one string constant that the
+- `bc' utility is guaranteed to support.
+-
+- - Macro: int COLL_WEIGHTS_MAX
+- The largest number of weights that can necessarily be used in
+- defining the collating sequence for a locale.
+-
+- - Macro: int EXPR_NEST_MAX
+- The maximum number of expressions that can be nested within
+- parenthesis by the `expr' utility.
+-
+- - Macro: int LINE_MAX
+- The largest text line that the text-oriented POSIX.2 utilities can
+- support. (If you are using the GNU versions of these utilities,
+- then there is no actual limit except that imposed by the available
+- virtual memory, but there is no way that the library can tell you
+- this.)

+-String-Valued Parameters
+-========================
+-
+- POSIX.2 defines a way to get string-valued parameters from the
+-operating system with the function `confstr':
+-
+- - Function: size_t confstr (int PARAMETER, char *BUF, size_t LEN)
+- This function reads the value of a string-valued system parameter,
+- storing the string into LEN bytes of memory space starting at BUF.
+- The PARAMETER argument should be one of the `_CS_' symbols listed
+- below.
+-
+- The normal return value from `confstr' is the length of the string
+- value that you asked for. If you supply a null pointer for BUF,
+- then `confstr' does not try to store the string; it just returns
+- its length. A value of `0' indicates an error.
+-
+- If the string you asked for is too long for the buffer (that is,
+- longer than `LEN - 1'), then `confstr' stores just that much
+- (leaving room for the terminating null character). You can tell
+- that this has happened because `confstr' returns a value greater
+- than or equal to LEN.
+-
+- The following `errno' error conditions are defined for this
+- function:
+-
+- `EINVAL'
+- The value of the PARAMETER is invalid.
+-
+- Currently there is just one parameter you can read with `confstr':
+-
+-`_CS_PATH'
+- This parameter's value is the recommended default path for
+- searching for executable files. This is the path that a user has
+- by default just after logging in.
+-
+-`_CS_LFS_CFLAGS'
+- The returned string specifies which additional flags must be given
+- to the C compiler if a source is compiled using the
+- `_LARGEFILE_SOURCE' feature select macro; *note Feature Test
+- Macros::.
+-
+-`_CS_LFS_LDFLAGS'
+- The returned string specifies which additional flags must be given
+- to the linker if a source is compiled using the
+- `_LARGEFILE_SOURCE' feature select macro; *note Feature Test
+- Macros::.
+-
+-`_CS_LFS_LIBS'
+- The returned string specifies which additional libraries must be
+- linked to the application if a source is compiled using the
+- `_LARGEFILE_SOURCE' feature select macro; *note Feature Test
+- Macros::.
+-
+-`_CS_LFS_LINTFLAGS'
+- The returned string specifies which additional flags must be given
+- to the lint tool if a source is compiled using the
+- `_LARGEFILE_SOURCE' feature select macro; *note Feature Test
+- Macros::.

+-DES Encryption and Password Handling
+-************************************
+-
+- On many systems, it is unnecessary to have any kind of user
+-authentication; for instance, a workstation which is not connected to a
+-network probably does not need any user authentication, because to use
+-the machine an intruder must have physical access.
+-
+- Sometimes, however, it is necessary to be sure that a user is
+-authorized to use some service a machine provides--for instance, to log
+-in as a particular user id (*note Users and Groups::). One traditional
+-way of doing this is for each user to choose a secret "password"; then,
+-the system can ask someone claiming to be a user what the user's
+-password is, and if the person gives the correct password then the
+-system can grant the appropriate privileges.
+-
+- If all the passwords are just stored in a file somewhere, then this
+-file has to be very carefully protected. To avoid this, passwords are
+-run through a "one-way function", a function which makes it difficult to
+-work out what its input was by looking at its output, before storing in
+-the file.
+-
+- The GNU C library provides a one-way function that is compatible with
+-the behavior of the `crypt' function introduced in FreeBSD 2.0. It
+-supports two one-way algorithms: one based on the MD5 message-digest
+-algorithm that is compatible with modern BSD systems, and the other
+-based on the Data Encryption Standard (DES) that is compatible with
+-Unix systems.
+-
+- It also provides support for Secure RPC, and some library functions
+-that can be used to perform normal DES encryption.

+-Legal Problems
+-==============
+-
+- Because of the continuously changing state of the law, it's not
+-possible to provide a definitive survey of the laws affecting
+-cryptography. Instead, this section warns you of some of the known
+-trouble spots; this may help you when you try to find out what the laws
+-of your country are.
+-
+- Some countries require that you have a licence to use, possess, or
+-import cryptography. These countries are believed to include
+-Byelorussia, Burma, India, Indonesia, Israel, Kazakhstan, Pakistan,
+-Russia, and Saudi Arabia.
+-
+- Some countries restrict the transmission of encrypted messages by
+-radio; some telecommunications carriers restrict the transmission of
+-encrypted messages over their network.
+-
+- Many countries have some form of export control for encryption
+-software. The Wassenaar Arrangement is a multilateral agreement
+-between 33 countries (Argentina, Australia, Austria, Belgium, Bulgaria,
+-Canada, the Czech Republic, Denmark, Finland, France, Germany, Greece,
+-Hungary, Ireland, Italy, Japan, Luxembourg, the Netherlands, New
+-Zealand, Norway, Poland, Portugal, the Republic of Korea, Romania, the
+-Russian Federation, the Slovak Republic, Spain, Sweden, Switzerland,
+-Turkey, Ukraine, the United Kingdom and the United States) which
+-restricts some kinds of encryption exports. Different countries apply
+-the arrangement in different ways; some do not allow the exception for
+-certain kinds of "public domain" software (which would include this
+-library), some only restrict the export of software in tangible form,
+-and others impose significant additional restrictions.
+-
+- The United States has additional rules. This software would
+-generally be exportable under 15 CFR 740.13(e), which permits exports of
+-"encryption source code" which is "publicly available" and which is
+-"not subject to an express agreement for the payment of a licensing fee
+-or royalty for commercial production or sale of any product developed
+-with the source code" to most countries.
+-
+- The rules in this area are continuously changing. If you know of any
+-information in this manual that is out-of-date, please report it using
+-the `glibcbug' script. *Note Reporting Bugs::.

+-Reading Passwords
+-=================
+-
+- When reading in a password, it is desirable to avoid displaying it on
+-the screen, to help keep it secret. The following function handles this
+-in a convenient way.
+-
+- - Function: char * getpass (const char *PROMPT)
+- `getpass' outputs PROMPT, then reads a string in from the terminal
+- without echoing it. It tries to connect to the real terminal,
+- `/dev/tty', if possible, to encourage users not to put plaintext
+- passwords in files; otherwise, it uses `stdin' and `stderr'.
+- `getpass' also disables the INTR, QUIT, and SUSP characters on the
+- terminal using the `ISIG' terminal attribute (*note Local Modes::).
+- The terminal is flushed before and after `getpass', so that
+- characters of a mistyped password are not accidentally visible.
+-
+- In other C libraries, `getpass' may only return the first
+- `PASS_MAX' bytes of a password. The GNU C library has no limit, so
+- `PASS_MAX' is undefined.
+-
+- The prototype for this function is in `unistd.h'. `PASS_MAX'
+- would be defined in `limits.h'.
+-
+- This precise set of operations may not suit all possible situations.
+-In this case, it is recommended that users write their own `getpass'
+-substitute. For instance, a very simple substitute is as follows:
+-
+- #include <termios.h>
+- #include <stdio.h>
+-
+- ssize_t
+- my_getpass (char **lineptr, size_t *n, FILE *stream)
+- {
+- struct termios old, new;
+- int nread;
+-
+- /* Turn echoing off and fail if we can't. */
+- if (tcgetattr (fileno (stream), &old) != 0)
+- return -1;
+- new = old;
+- new.c_lflag &= ~ECHO;
+- if (tcsetattr (fileno (stream), TCSAFLUSH, &new) != 0)
+- return -1;
+-
+- /* Read the password. */
+- nread = getline (lineptr, n, stream);
+-
+- /* Restore terminal. */
+- (void) tcsetattr (fileno (stream), TCSAFLUSH, &old);
+-
+- return nread;
+- }
+-
+- The substitute takes the same parameters as `getline' (*note Line
+-Input::); the user must print any prompt desired.

+-
+-Encrypting Passwords
+-====================
+-
+- - Function: char * crypt (const char *KEY, const char *SALT)
+- The `crypt' function takes a password, KEY, as a string, and a
+- SALT character array which is described below, and returns a
+- printable ASCII string which starts with another salt. It is
+- believed that, given the output of the function, the best way to
+- find a KEY that will produce that output is to guess values of KEY
+- until the original value of KEY is found.
+-
+- The SALT parameter does two things. Firstly, it selects which
+- algorithm is used, the MD5-based one or the DES-based one.
+- Secondly, it makes life harder for someone trying to guess
+- passwords against a file containing many passwords; without a
+- SALT, an intruder can make a guess, run `crypt' on it once, and
+- compare the result with all the passwords. With a SALT, the
+- intruder must run `crypt' once for each different salt.
+-
+- For the MD5-based algorithm, the SALT should consist of the string
+- `$1$', followed by up to 8 characters, terminated by either
+- another `$' or the end of the string. The result of `crypt' will
+- be the SALT, followed by a `$' if the salt didn't end with one,
+- followed by 22 characters from the alphabet `./0-9A-Za-z', up to
+- 34 characters total. Every character in the KEY is significant.
+-
+- For the DES-based algorithm, the SALT should consist of two
+- characters from the alphabet `./0-9A-Za-z', and the result of
+- `crypt' will be those two characters followed by 11 more from the
+- same alphabet, 13 in total. Only the first 8 characters in the
+- KEY are significant.
+-
+- The MD5-based algorithm has no limit on the useful length of the
+- password used, and is slightly more secure. It is therefore
+- preferred over the DES-based algorithm.
+-
+- When the user enters their password for the first time, the SALT
+- should be set to a new string which is reasonably random. To
+- verify a password against the result of a previous call to
+- `crypt', pass the result of the previous call as the SALT.
+-
+- The following short program is an example of how to use `crypt' the
+-first time a password is entered. Note that the SALT generation is
+-just barely acceptable; in particular, it is not unique between
+-machines, and in many applications it would not be acceptable to let an
+-attacker know what time the user's password was last set.

+- #include <stdio.h>
+- #include <time.h>

+- return ok ? 0 : 1;
+- }
+-
+- - Function: char * crypt_r (const char *KEY, const char *SALT, struct
+- crypt_data * DATA)
+- The `crypt_r' function does the same thing as `crypt', but takes
+- an extra parameter which includes space for its result (among
+- other things), so it can be reentrant. `data->initialized' must be
+- cleared to zero before the first time `crypt_r' is called.

+-DES Encryption
+-==============
+-
+- The Data Encryption Standard is described in the US Government
+-Federal Information Processing Standards (FIPS) 46-3 published by the
+-National Institute of Standards and Technology. The DES has been very
+-thoroughly analyzed since it was developed in the late 1970s, and no new
+-significant flaws have been found.
+-
+- However, the DES uses only a 56-bit key (plus 8 parity bits), and a
+-machine has been built in 1998 which can search through all possible
+-keys in about 6 days, which cost about US$200000; faster searches would
+-be possible with more money. This makes simple DES insecure for most
+-purposes, and NIST no longer permits new US government systems to use
+-simple DES.
+-
+- For serious encryption functionality, it is recommended that one of
+-the many free encryption libraries be used instead of these routines.
+-
+- The DES is a reversible operation which takes a 64-bit block and a
+-64-bit key, and produces another 64-bit block. Usually the bits are
+-numbered so that the most-significant bit, the first bit, of each block
+-is numbered 1.
+-
+- Under that numbering, every 8th bit of the key (the 8th, 16th, and so
+-on) is not used by the encryption algorithm itself. But the key must
+-have odd parity; that is, out of bits 1 through 8, and 9 through 16, and
+-so on, there must be an odd number of `1' bits, and this completely
+-specifies the unused bits.
+-
+- - Function: void setkey (const char *KEY)
+- The `setkey' function sets an internal data structure to be an
+- expanded form of KEY. KEY is specified as an array of 64 bits
+- each stored in a `char', the first bit is `key[0]' and the 64th
+- bit is `key[63]'. The KEY should have the correct parity.
+-
+- - Function: void encrypt (char *BLOCK, int EDFLAG)
+- The `encrypt' function encrypts BLOCK if EDFLAG is 0, otherwise it
+- decrypts BLOCK, using a key previously set by `setkey'. The
+- result is placed in BLOCK.
+-
+- Like `setkey', BLOCK is specified as an array of 64 bits each
+- stored in a `char', but there are no parity bits in BLOCK.
+-
+- - Function: void setkey_r (const char *KEY, struct crypt_data * DATA)
+- - Function: void encrypt_r (char *BLOCK, int EDFLAG, struct crypt_data
+- * DATA)
+- These are reentrant versions of `setkey' and `encrypt'. The only
+- difference is the extra parameter, which stores the expanded
+- version of KEY. Before calling `setkey_r' the first time,
+- `data->initialized' must be cleared to zero.
+-
+- The `setkey_r' and `encrypt_r' functions are GNU extensions.
+-`setkey', `encrypt', `setkey_r', and `encrypt_r' are defined in
+-`crypt.h'.
+-
+- - Function: int ecb_crypt (char *KEY, char *BLOCKS, unsigned LEN,
+- unsigned MODE)
+- The function `ecb_crypt' encrypts or decrypts one or more blocks
+- using DES. Each block is encrypted independently.
+-
+- The BLOCKS and the KEY are stored packed in 8-bit bytes, so that
+- the first bit of the key is the most-significant bit of `key[0]'
+- and the 63rd bit of the key is stored as the least-significant bit
+- of `key[7]'. The KEY should have the correct parity.
+-
+- LEN is the number of bytes in BLOCKS. It should be a multiple of
+- 8 (so that there is a whole number of blocks to encrypt). LEN is
+- limited to a maximum of `DES_MAXDATA' bytes.
+-
+- The result of the encryption replaces the input in BLOCKS.
+-
+- The MODE parameter is the bitwise OR of two of the following:
+-
+- `DES_ENCRYPT'
+- This constant, used in the MODE parameter, specifies that
+- BLOCKS is to be encrypted.
+-
+- `DES_DECRYPT'
+- This constant, used in the MODE parameter, specifies that
+- BLOCKS is to be decrypted.
+-
+- `DES_HW'
+- This constant, used in the MODE parameter, asks to use a
+- hardware device. If no hardware device is available,
+- encryption happens anyway, but in software.
+-
+- `DES_SW'
+- This constant, used in the MODE parameter, specifies that no
+- hardware device is to be used.
+-
+- The result of the function will be one of these values:
+-
+- `DESERR_NONE'
+- The encryption succeeded.
+-
+- `DESERR_NOHWDEVICE'
+- The encryption succeeded, but there was no hardware device
+- available.
+-
+- `DESERR_HWERROR'
+- The encryption failed because of a hardware problem.
+-
+- `DESERR_BADPARAM'
+- The encryption failed because of a bad parameter, for
+- instance LEN is not a multiple of 8 or LEN is larger than
+- `DES_MAXDATA'.
+-
+- - Function: int DES_FAILED (int ERR)
+- This macro returns 1 if ERR is a `success' result code from
+- `ecb_crypt' or `cbc_crypt', and 0 otherwise.
+-
+- - Function: int cbc_crypt (char *KEY, char *BLOCKS, unsigned LEN,
+- unsigned MODE, char *IVEC)
+- The function `cbc_crypt' encrypts or decrypts one or more blocks
+- using DES in Cipher Block Chaining mode.
+-
+- For encryption in CBC mode, each block is exclusive-ored with IVEC
+- before being encrypted, then IVEC is replaced with the result of
+- the encryption, then the next block is processed. Decryption is
+- the reverse of this process.
+-
+- This has the advantage that blocks which are the same before being
+- encrypted are very unlikely to be the same after being encrypted,
+- making it much harder to detect patterns in the data.
+-
+- Usually, IVEC is set to 8 random bytes before encryption starts.
+- Then the 8 random bytes are transmitted along with the encrypted
+- data (without themselves being encrypted), and passed back in as
+- IVEC for decryption. Another possibility is to set IVEC to 8
+- zeroes initially, and have the first the block encrypted consist
+- of 8 random bytes.
+-
+- Otherwise, all the parameters are similar to those for `ecb_crypt'.
+-
+- - Function: void des_setparity (char *KEY)
+- The function `des_setparity' changes the 64-bit KEY, stored packed
+- in 8-bit bytes, to have odd parity by altering the low bits of
+- each byte.
+-
+- The `ecb_crypt', `cbc_crypt', and `des_setparity' functions and
+-their accompanying macros are all defined in the header
+-`rpc/des_crypt.h'.

+-
+- Applications are usually debugged using dedicated debugger programs.
+-But sometimes this is not possible and, in any case, it is useful to
+-provide the developer with as much information as possible at the time
+-the problems are experienced. For this reason a few functions are
+-provided which a program can use to help the developer more easily
+-locate the problem.

+-
+-Backtraces
+-==========
+-
+- A "backtrace" is a list of the function calls that are currently
+-active in a thread. The usual way to inspect a backtrace of a program
+-is to use an external debugger such as gdb. However, sometimes it is
+-useful to obtain a backtrace programmatically from within a program,
+-e.g., for the purposes of logging or diagnostics.
+-
+- The header file `execinfo.h' declares three functions that obtain
+-and manipulate backtraces of the current thread.
+-
+- - Function: int backtrace (void **BUFFER, int SIZE)
+- The `backtrace' function obtains a backtrace for the current
+- thread, as a list of pointers, and places the information into
+- BUFFER. The argument SIZE should be the number of `void *'
+- elements that will fit into BUFFER. The return value is the
+- actual number of entries of BUFFER that are obtained, and is at
+- most SIZE.
+-
+- The pointers placed in BUFFER are actually return addresses
+- obtained by inspecting the stack, one return address per stack
+- frame.
+-
+- Note that certain compiler optimizations may interfere with
+- obtaining a valid backtrace. Function inlining causes the inlined
+- function to not have a stack frame; tail call optimization
+- replaces one stack frame with another; frame pointer elimination
+- will stop `backtrace' from interpreting the stack contents
+- correctly.
+-
+- - Function: char ** backtrace_symbols (void *const *BUFFER, int SIZE)
+- The `backtrace_symbols' function translates the information
+- obtained from the `backtrace' function into an array of strings.
+- The argument BUFFER should be a pointer to an array of addresses
+- obtained via the `backtrace' function, and SIZE is the number of
+- entries in that array (the return value of `backtrace').
+-
+- The return value is a pointer to an array of strings, which has
+- SIZE entries just like the array BUFFER. Each string contains a
+- printable representation of the corresponding element of BUFFER.
+- It includes the function name (if this can be determined), an
+- offset into the function, and the actual return address (in
+- hexadecimal).
+-
+- Currently, the function name and offset only be obtained on
+- systems that use the ELF binary format for programs and libraries.
+- On other systems, only the hexadecimal return address will be
+- present. Also, you may need to pass additional flags to the
+- linker to make the function names available to the program. (For
+- example, on systems using GNU ld, you must pass (`-rdynamic'.)
+-
+- The return value of `backtrace_symbols' is a pointer obtained via
+- the `malloc' function, and it is the responsibility of the caller
+- to `free' that pointer. Note that only the return value need be
+- freed, not the individual strings.
+-
+- The return value is `NULL' if sufficient memory for the strings
+- cannot be obtained.
+-
+- - Function: void backtrace_symbols_fd (void *const *BUFFER, int SIZE,
+- int FD)
+- The `backtrace_symbols_fd' function performs the same translation
+- as the function `backtrace_symbols' function. Instead of returning
+- the strings to the caller, it writes the strings to the file
+- descriptor FD, one per line. It does not use the `malloc'
+- function, and can therefore be used in situations where that
+- function might fail.
+-
+- The following program illustrates the use of these functions. Note
+-that the array to contain the return addresses returned by `backtrace'
+-is allocated on the stack. Therefore code like this can be used in
+-situations where the memory handling via `malloc' does not work anymore
+-(in which case the `backtrace_symbols' has to be replaced by a
+-`backtrace_symbols_fd' call as well). The number of return addresses
+-is normally not very large. Even complicated programs rather seldom
+-have a nesting level of more than, say, 50 and with 200 possible
+-entries probably all programs should be covered.

+- You don't need to do anything special when you start to grow an
+-object. Using one of the functions to add data to the object
+-automatically starts it. However, it is necessary to say explicitly
+-when the object is finished. This is done with the function
+-`obstack_finish'.
+-
+- The actual address of the object thus built up is not known until the
+-object is finished. Until then, it always remains possible that you
+-will add so much data that the object must be copied into a new chunk.
+-
+- While the obstack is in use for a growing object, you cannot use it
+-for ordinary allocation of another object. If you try to do so, the
+-space already added to the growing object will become part of the other
+-object.
+-
+- - Function: void obstack_blank (struct obstack *OBSTACK-PTR, int SIZE)
+- The most basic function for adding to a growing object is
+- `obstack_blank', which adds space without initializing it.
+-
+- - Function: void obstack_grow (struct obstack *OBSTACK-PTR, void
+- *DATA, int SIZE)
+- To add a block of initialized space, use `obstack_grow', which is
+- the growing-object analogue of `obstack_copy'. It adds SIZE bytes
+- of data to the growing object, copying the contents from DATA.
+-
+- - Function: void obstack_grow0 (struct obstack *OBSTACK-PTR, void
+- *DATA, int SIZE)
+- This is the growing-object analogue of `obstack_copy0'. It adds
+- SIZE bytes copied from DATA, followed by an additional null
+- character.
+-
+- - Function: void obstack_1grow (struct obstack *OBSTACK-PTR, char C)
+- To add one character at a time, use the function `obstack_1grow'.
+- It adds a single byte containing C to the growing object.
+-
+- - Function: void obstack_ptr_grow (struct obstack *OBSTACK-PTR, void
+- *DATA)
+- Adding the value of a pointer one can use the function
+- `obstack_ptr_grow'. It adds `sizeof (void *)' bytes containing
+- the value of DATA.
+-
+- - Function: void obstack_int_grow (struct obstack *OBSTACK-PTR, int
+- DATA)
+- A single value of type `int' can be added by using the
+- `obstack_int_grow' function. It adds `sizeof (int)' bytes to the
+- growing object and initializes them with the value of DATA.
+-
+- - Function: void * obstack_finish (struct obstack *OBSTACK-PTR)
+- When you are finished growing the object, use the function
+- `obstack_finish' to close it off and return its final address.
+-
+- Once you have finished the object, the obstack is available for
+- ordinary allocation or for growing another object.
+-
+- This function can return a null pointer under the same conditions
+- as `obstack_alloc' (*note Allocation in an Obstack::).
+-
+- When you build an object by growing it, you will probably need to
+-know afterward how long it became. You need not keep track of this as
+-you grow the object, because you can find out the length from the
+-obstack just before finishing the object with the function
+-`obstack_object_size', declared as follows:
+-
+- - Function: int obstack_object_size (struct obstack *OBSTACK-PTR)
+- This function returns the current size of the growing object, in
+- bytes. Remember to call this function _before_ finishing the
+- object. After it is finished, `obstack_object_size' will return
+- zero.
+-
+- If you have started growing an object and wish to cancel it, you
+-should finish it and then free it, like this:
+-
+- obstack_free (obstack_ptr, obstack_finish (obstack_ptr));
+-
+-This has no effect if no object was growing.
+-
+- You can use `obstack_blank' with a negative size argument to make
+-the current object smaller. Just don't try to shrink it beyond zero
+-length--there's no telling what will happen if you do that.

+-Extra Fast Growing Objects
+-..........................
+-
+- The usual functions for growing objects incur overhead for checking
+-whether there is room for the new growth in the current chunk. If you
+-are frequently constructing objects in small steps of growth, this
+-overhead can be significant.
+-
+- You can reduce the overhead by using special "fast growth" functions
+-that grow the object without checking. In order to have a robust
+-program, you must do the checking yourself. If you do this checking in
+-the simplest way each time you are about to add data to the object, you
+-have not saved anything, because that is what the ordinary growth
+-functions do. But if you can arrange to check less often, or check
+-more efficiently, then you make the program faster.
+-
+- The function `obstack_room' returns the amount of room available in
+-the current chunk. It is declared as follows:
+-
+- - Function: int obstack_room (struct obstack *OBSTACK-PTR)
+- This returns the number of bytes that can be added safely to the
+- current growing object (or to an object about to be started) in
+- obstack OBSTACK using the fast growth functions.
+-
+- While you know there is room, you can use these fast growth functions
+-for adding data to a growing object:
+-
+- - Function: void obstack_1grow_fast (struct obstack *OBSTACK-PTR, char
+- C)
+- The function `obstack_1grow_fast' adds one byte containing the
+- character C to the growing object in obstack OBSTACK-PTR.
+-
+- - Function: void obstack_ptr_grow_fast (struct obstack *OBSTACK-PTR,
+- void *DATA)
+- The function `obstack_ptr_grow_fast' adds `sizeof (void *)' bytes
+- containing the value of DATA to the growing object in obstack
+- OBSTACK-PTR.
+-
+- - Function: void obstack_int_grow_fast (struct obstack *OBSTACK-PTR,
+- int DATA)
+- The function `obstack_int_grow_fast' adds `sizeof (int)' bytes
+- containing the value of DATA to the growing object in obstack
+- OBSTACK-PTR.
+-
+- - Function: void obstack_blank_fast (struct obstack *OBSTACK-PTR, int
+- SIZE)
+- The function `obstack_blank_fast' adds SIZE bytes to the growing
+- object in obstack OBSTACK-PTR without initializing them.
+-
+- When you check for space using `obstack_room' and there is not
+-enough room for what you want to add, the fast growth functions are not
+-safe. In this case, simply use the corresponding ordinary growth
+-function instead. Very soon this will copy the object to a new chunk;
+-then there will be lots of room available again.
+-
+- So, each time you use an ordinary growth function, check afterward
+-for sufficient space using `obstack_room'. Once the object is copied
+-to a new chunk, there will be plenty of space again, so the program will
+-start using the fast growth functions again.
+-
+- Here is an example:
+-
+- void
+- add_string (struct obstack *obstack, const char *ptr, int len)
+- {
+- while (len > 0)
+- {
+- int room = obstack_room (obstack);
+- if (room == 0)
+- {
+- /* Not enough room. Add one character slowly,
+- which may copy to a new chunk and make room. */
+- obstack_1grow (obstack, *ptr++);
+- len--;
+- }
+- else
+- {
+- if (room > len)
+- room = len;
+- /* Add fast as much as we have room for. */
+- len -= room;
+- while (room-- > 0)
+- obstack_1grow_fast (obstack, *ptr++);
+- }
+- }
+- }

+-
+-Status of an Obstack
+-....................
+-
+- Here are functions that provide information on the current status of
+-allocation in an obstack. You can use them to learn about an object
+-while still growing it.
+-
+- - Function: void * obstack_base (struct obstack *OBSTACK-PTR)
+- This function returns the tentative address of the beginning of the
+- currently growing object in OBSTACK-PTR. If you finish the object
+- immediately, it will have that address. If you make it larger
+- first, it may outgrow the current chunk--then its address will
+- change!
+-
+- If no object is growing, this value says where the next object you
+- allocate will start (once again assuming it fits in the current
+- chunk).
+-
+- - Function: void * obstack_next_free (struct obstack *OBSTACK-PTR)
+- This function returns the address of the first free byte in the
+- current chunk of obstack OBSTACK-PTR. This is the end of the
+- currently growing object. If no object is growing,
+- `obstack_next_free' returns the same value as `obstack_base'.
+-
+- - Function: int obstack_object_size (struct obstack *OBSTACK-PTR)
+- This function returns the size in bytes of the currently growing
+- object. This is equivalent to
+-
+- obstack_next_free (OBSTACK-PTR) - obstack_base (OBSTACK-PTR)
+-
+-\1f
+-File: libc.info, Node: Obstacks Data Alignment, Next: Obstack Chunks, Prev: Status of an Obstack, Up: Obstacks
+-
+-Alignment of Data in Obstacks
+-.............................
+-
+- Each obstack has an "alignment boundary"; each object allocated in
+-the obstack automatically starts on an address that is a multiple of the
+-specified boundary. By default, this boundary is 4 bytes.
+-
+- To access an obstack's alignment boundary, use the macro
+-`obstack_alignment_mask', whose function prototype looks like this:
+-
+- - Macro: int obstack_alignment_mask (struct obstack *OBSTACK-PTR)
+- The value is a bit mask; a bit that is 1 indicates that the
+- corresponding bit in the address of an object should be 0. The
+- mask value should be one less than a power of 2; the effect is
+- that all object addresses are multiples of that power of 2. The
+- default value of the mask is 3, so that addresses are multiples of
+- 4. A mask value of 0 means an object can start on any multiple of
+- 1 (that is, no alignment is required).
+-
+- The expansion of the macro `obstack_alignment_mask' is an lvalue,
+- so you can alter the mask by assignment. For example, this
+- statement:
+-
+- obstack_alignment_mask (obstack_ptr) = 0;
+-
+- has the effect of turning off alignment processing in the
+- specified obstack.
+-
+- Note that a change in alignment mask does not take effect until
+-_after_ the next time an object is allocated or finished in the
+-obstack. If you are not growing an object, you can make the new
+-alignment mask take effect immediately by calling `obstack_finish'.
+-This will finish a zero-length object and then do proper alignment for
+-the next object.

+-
+-Obstack Chunks
+-..............
+-
+- Obstacks work by allocating space for themselves in large chunks, and
+-then parceling out space in the chunks to satisfy your requests. Chunks
+-are normally 4096 bytes long unless you specify a different chunk size.
+-The chunk size includes 8 bytes of overhead that are not actually used
+-for storing objects. Regardless of the specified size, longer chunks
+-will be allocated when necessary for long objects.
+-
+- The obstack library allocates chunks by calling the function
+-`obstack_chunk_alloc', which you must define. When a chunk is no
+-longer needed because you have freed all the objects in it, the obstack
+-library frees the chunk by calling `obstack_chunk_free', which you must
+-also define.
+-
+- These two must be defined (as macros) or declared (as functions) in
+-each source file that uses `obstack_init' (*note Creating Obstacks::).
+-Most often they are defined as macros like this:
+-
+- #define obstack_chunk_alloc malloc
+- #define obstack_chunk_free free
+-
+- Note that these are simple macros (no arguments). Macro definitions
+-with arguments will not work! It is necessary that
+-`obstack_chunk_alloc' or `obstack_chunk_free', alone, expand into a
+-function name if it is not itself a function name.
+-
+- If you allocate chunks with `malloc', the chunk size should be a
+-power of 2. The default chunk size, 4096, was chosen because it is long
+-enough to satisfy many typical requests on the obstack yet short enough
+-not to waste too much memory in the portion of the last chunk not yet
+-used.
+-
+- - Macro: int obstack_chunk_size (struct obstack *OBSTACK-PTR)
+- This returns the chunk size of the given obstack.
+-
+- Since this macro expands to an lvalue, you can specify a new chunk
+-size by assigning it a new value. Doing so does not affect the chunks
+-already allocated, but will change the size of chunks allocated for
+-that particular obstack in the future. It is unlikely to be useful to
+-make the chunk size smaller, but making it larger might improve
+-efficiency if you are allocating many objects whose size is comparable
+-to the chunk size. Here is how to do so cleanly:
+-
+- if (obstack_chunk_size (obstack_ptr) < NEW-CHUNK-SIZE)
+- obstack_chunk_size (obstack_ptr) = NEW-CHUNK-SIZE;

+-Automatic Storage with Variable Size
+-------------------------------------
+-
+- The function `alloca' supports a kind of half-dynamic allocation in
+-which blocks are allocated dynamically but freed automatically.
+-
+- Allocating a block with `alloca' is an explicit action; you can
+-allocate as many blocks as you wish, and compute the size at run time.
+-But all the blocks are freed when you exit the function that `alloca'
+-was called from, just as if they were automatic variables declared in
+-that function. There is no way to free the space explicitly.
+-
+- The prototype for `alloca' is in `stdlib.h'. This function is a BSD
+-extension.
+-
+- - Function: void * alloca (size_t SIZE);
+- The return value of `alloca' is the address of a block of SIZE
+- bytes of memory, allocated in the stack frame of the calling
+- function.
+-
+- Do not use `alloca' inside the arguments of a function call--you
+-will get unpredictable results, because the stack space for the
+-`alloca' would appear on the stack in the middle of the space for the
+-function arguments. An example of what to avoid is `foo (x, alloca
+-(4), y)'.

+-
+-`alloca' Example
+-................
+-
+- As an example of the use of `alloca', here is a function that opens
+-a file name made from concatenating two argument strings, and returns a
+-file descriptor or minus one signifying failure:
+-
+- int
+- open2 (char *str1, char *str2, int flags, int mode)
+- {
+- char *name = (char *) alloca (strlen (str1) + strlen (str2) + 1);
+- stpcpy (stpcpy (name, str1), str2);
+- return open (name, flags, mode);
+- }
+-
+-Here is how you would get the same results with `malloc' and `free':
+-
+- int
+- open2 (char *str1, char *str2, int flags, int mode)
+- {
+- char *name = (char *) malloc (strlen (str1) + strlen (str2) + 1);
+- int desc;
+- if (name == 0)
+- fatal ("virtual memory exceeded");
+- stpcpy (stpcpy (name, str1), str2);
+- desc = open (name, flags, mode);
+- free (name);
+- return desc;
+- }
+-
+- As you can see, it is simpler with `alloca'. But `alloca' has
+-other, more important advantages, and some disadvantages.
+-
+-\1f
+-File: libc.info, Node: Advantages of Alloca, Next: Disadvantages of Alloca, Prev: Alloca Example, Up: Variable Size Automatic
+-
+-Advantages of `alloca'
+-......................
+-
+- Here are the reasons why `alloca' may be preferable to `malloc':
+-
+- * Using `alloca' wastes very little space and is very fast. (It is
+- open-coded by the GNU C compiler.)
+-
+- * Since `alloca' does not have separate pools for different sizes of
+- block, space used for any size block can be reused for any other
+- size. `alloca' does not cause memory fragmentation.
+-
+- * Nonlocal exits done with `longjmp' (*note Non-Local Exits::)
+- automatically free the space allocated with `alloca' when they exit
+- through the function that called `alloca'. This is the most
+- important reason to use `alloca'.
+-
+- To illustrate this, suppose you have a function
+- `open_or_report_error' which returns a descriptor, like `open', if
+- it succeeds, but does not return to its caller if it fails. If
+- the file cannot be opened, it prints an error message and jumps
+- out to the command level of your program using `longjmp'. Let's
+- change `open2' (*note Alloca Example::) to use this subroutine:
+-
+- int
+- open2 (char *str1, char *str2, int flags, int mode)
+- {
+- char *name = (char *) alloca (strlen (str1) + strlen (str2) + 1);
+- stpcpy (stpcpy (name, str1), str2);
+- return open_or_report_error (name, flags, mode);
+- }
+-
+- Because of the way `alloca' works, the memory it allocates is
+- freed even when an error occurs, with no special effort required.
+-
+- By contrast, the previous definition of `open2' (which uses
+- `malloc' and `free') would develop a memory leak if it were
+- changed in this way. Even if you are willing to make more changes
+- to fix it, there is no easy way to do so.
+-
+-\1f
+-File: libc.info, Node: Disadvantages of Alloca, Next: GNU C Variable-Size Arrays, Prev: Advantages of Alloca, Up: Variable Size Automatic
+-
+-Disadvantages of `alloca'
+-.........................
+-
+- These are the disadvantages of `alloca' in comparison with `malloc':
+-
+- * If you try to allocate more memory than the machine can provide,
+- you don't get a clean error message. Instead you get a fatal
+- signal like the one you would get from an infinite recursion;
+- probably a segmentation violation (*note Program Error Signals::).
+-
+- * Some non-GNU systems fail to support `alloca', so it is less
+- portable. However, a slower emulation of `alloca' written in C is
+- available for use on systems with this deficiency.
+-
+-\1f
+-File: libc.info, Node: GNU C Variable-Size Arrays, Prev: Disadvantages of Alloca, Up: Variable Size Automatic
+-
+-GNU C Variable-Size Arrays
+-..........................
+-
+- In GNU C, you can replace most uses of `alloca' with an array of
+-variable size. Here is how `open2' would look then:
+-
+- int open2 (char *str1, char *str2, int flags, int mode)
+- {
+- char name[strlen (str1) + strlen (str2) + 1];
+- stpcpy (stpcpy (name, str1), str2);
+- return open (name, flags, mode);
+- }
+-
+- But `alloca' is not always equivalent to a variable-sized array, for
+-several reasons:
+-
+- * A variable size array's space is freed at the end of the scope of
+- the name of the array. The space allocated with `alloca' remains
+- until the end of the function.
+-
+- * It is possible to use `alloca' within a loop, allocating an
+- additional block on each iteration. This is impossible with
+- variable-sized arrays.
+-
+- *Note:* If you mix use of `alloca' and variable-sized arrays within
+-one function, exiting a scope in which a variable-sized array was
+-declared frees all blocks allocated with `alloca' during the execution
+-of that scope.

+-Resizing the Data Segment
+-=========================
+-
+- The symbols in this section are declared in `unistd.h'.
+-
+- You will not normally use the functions in this section, because the
+-functions described in *Note Memory Allocation:: are easier to use.
+-Those are interfaces to a GNU C Library memory allocator that uses the
+-functions below itself. The functions below are simple interfaces to
+-system calls.
+-
+- - Function: int brk (void *ADDR)
+- `brk' sets the high end of the calling process' data segment to
+- ADDR.
+-
+- The address of the end of a segment is defined to be the address
+- of the last byte in the segment plus 1.
+-
+- The function has no effect if ADDR is lower than the low end of
+- the data segment. (This is considered success, by the way).
+-
+- The function fails if it would cause the data segment to overlap
+- another segment or exceed the process' data storage limit (*note
+- Limits on Resources::).
+-
+- The function is named for a common historical case where data
+- storage and the stack are in the same segment. Data storage
+- allocation grows upward from the bottom of the segment while the
+- stack grows downward toward it from the top of the segment and the
+- curtain between them is called the "break".
+-
+- The return value is zero on success. On failure, the return value
+- is `-1' and `errno' is set accordingly. The following `errno'
+- values are specific to this function:
+-
+- `ENOMEM'
+- The request would cause the data segment to overlap another
+- segment or exceed the process' data storage limit.
+-
+-
+- - Function: int sbrk (ptrdiff_t DELTA)
+- This function is the same as `brk' except that you specify the new
+- end of the data segment as an offset DELTA from the current end
+- and on success the return value is the address of the resulting
+- end of the data segment instead of zero.
+-
+- This means you can use `sbrk(0)' to find out what the current end
+- of the data segment is.

+-Locking Pages
+-=============
+-
+- You can tell the system to associate a particular virtual memory page
+-with a real page frame and keep it that way -- i.e. cause the page to
+-be paged in if it isn't already and mark it so it will never be paged
+-out and consequently will never cause a page fault. This is called
+-"locking" a page.
+-
+- The functions in this chapter lock and unlock the calling process'
+-pages.
+-

+-
+-* Why Lock Pages:: Reasons to read this section.

+- memory

+-

+-File: libc.info, Node: Why Lock Pages, Next: Locked Memory Details, Up: Locking Pages
+-
+-Why Lock Pages
+---------------
+-
+- Because page faults cause paged out pages to be paged in
+-transparently, a process rarely needs to be concerned about locking
+-pages. However, there are two reasons people sometimes are:
+-
+- * Speed. A page fault is transparent only insofar as the process is
+- not sensitive to how long it takes to do a simple memory access.
+- Time-critical processes, especially realtime processes, may not be
+- able to wait or may not be able to tolerate variance in execution
+- speed.
+-
+- A process that needs to lock pages for this reason probably also
+- needs priority among other processes for use of the CPU. *Note
+- Priority::.
+-
+- In some cases, the programmer knows better than the system's demand
+- paging allocator which pages should remain in real memory to
+- optimize system performance. In this case, locking pages can help.
+-
+- * Privacy. If you keep secrets in virtual memory and that virtual
+- memory gets paged out, that increases the chance that the secrets
+- will get out. If a password gets written out to disk swap space,
+- for example, it might still be there long after virtual and real
+- memory have been wiped clean.
+-
+-
+- Be aware that when you lock a page, that's one fewer page frame that
+-can be used to back other virtual memory (by the same or other
+-processes), which can mean more page faults, which means the system
+-runs more slowly. In fact, if you lock enough memory, some programs
+-may not be able to run at all for lack of real memory.
+-
+-\1f
+-File: libc.info, Node: Locked Memory Details, Next: Page Lock Functions, Prev: Why Lock Pages, Up: Locking Pages
+-
+-Locked Memory Details
+----------------------
+-
+- A memory lock is associated with a virtual page, not a real frame.
+-The paging rule is: If a frame backs at least one locked page, don't
+-page it out.
+-
+- Memory locks do not stack. I.e. you can't lock a particular page
+-twice so that it has to be unlocked twice before it is truly unlocked.
+-It is either locked or it isn't.
+-
+- A memory lock persists until the process that owns the memory
+-explicitly unlocks it. (But process termination and exec cause the
+-virtual memory to cease to exist, which you might say means it isn't
+-locked any more).
+-
+- Memory locks are not inherited by child processes. (But note that
+-on a modern Unix system, immediately after a fork, the parent's and the
+-child's virtual address space are backed by the same real page frames,
+-so the child enjoys the parent's locks). *Note Creating a Process::.
+-
+- Because of its ability to impact other processes, only the superuser
+-can lock a page. Any process can unlock its own page.
+-
+- The system sets limits on the amount of memory a process can have
+-locked and the amount of real memory it can have dedicated to it.
+-*Note Limits on Resources::.
+-
+- In Linux, locked pages aren't as locked as you might think. Two
+-virtual pages that are not shared memory can nonetheless be backed by
+-the same real frame. The kernel does this in the name of efficiency
+-when it knows both virtual pages contain identical data, and does it
+-even if one or both of the virtual pages are locked.
+-
+- But when a process modifies one of those pages, the kernel must get
+-it a separate frame and fill it with the page's data. This is known as
+-a "copy-on-write page fault". It takes a small amount of time and in a
+-pathological case, getting that frame may require I/O.
+-
+- To make sure this doesn't happen to your program, don't just lock the
+-pages. Write to them as well, unless you know you won't write to them
+-ever. And to make sure you have pre-allocated frames for your stack,
+-enter a scope that declares a C automatic variable larger than the
+-maximum stack size you will need, set it to something, then return from
+-its scope.

+-Functions To Lock And Unlock Pages
+-----------------------------------
+-
+- The symbols in this section are declared in `sys/mman.h'. These
+-functions are defined by POSIX.1b, but their availability depends on
+-your kernel. If your kernel doesn't allow these functions, they exist
+-but always fail. They _are_ available with a Linux kernel.
+-
+- *Portability Note:* POSIX.1b requires that when the `mlock' and
+-`munlock' functions are available, the file `unistd.h' define the macro
+-`_POSIX_MEMLOCK_RANGE' and the file `limits.h' define the macro
+-`PAGESIZE' to be the size of a memory page in bytes. It requires that
+-when the `mlockall' and `munlockall' functions are available, the
+-`unistd.h' file define the macro `_POSIX_MEMLOCK'. The GNU C library
+-conforms to this requirement.
+-
+- - Function: int mlock (const void *ADDR, size_t LEN)
+- `mlock' locks a range of the calling process' virtual pages.
+-
+- The range of memory starts at address ADDR and is LEN bytes long.
+- Actually, since you must lock whole pages, it is the range of
+- pages that include any part of the specified range.
+-
+- When the function returns successfully, each of those pages is
+- backed by (connected to) a real frame (is resident) and is marked
+- to stay that way. This means the function may cause page-ins and
+- have to wait for them.
+-
+- When the function fails, it does not affect the lock status of any
+- pages.
+-
+- The return value is zero if the function succeeds. Otherwise, it
+- is `-1' and `errno' is set accordingly. `errno' values specific
+- to this function are:
+-
+- `ENOMEM'
+- * At least some of the specified address range does not
+- exist in the calling process' virtual address space.
+-
+- * The locking would cause the process to exceed its locked
+- page limit.
+-
+- `EPERM'
+- The calling process is not superuser.
+-
+- `EINVAL'
+- LEN is not positive.
+-
+- `ENOSYS'
+- The kernel does not provide `mlock' capability.
+-
+- You can lock _all_ a process' memory with `mlockall'. You unlock
+- memory with `munlock' or `munlockall'.
+-
+- To avoid all page faults in a C program, you have to use
+- `mlockall', because some of the memory a program uses is hidden
+- from the C code, e.g. the stack and automatic variables, and you
+- wouldn't know what address to tell `mlock'.
+-
+-
+- - Function: int munlock (const void *ADDR, size_t LEN)
+- `mlock' unlocks a range of the calling process' virtual pages.
+-
+- `munlock' is the inverse of `mlock' and functions completely
+- analogously to `mlock', except that there is no `EPERM' failure.
+-
+-
+- - Function: int mlockall (int FLAGS)
+- `mlockall' locks all the pages in a process' virtual memory address
+- space, and/or any that are added to it in the future. This
+- includes the pages of the code, data and stack segment, as well as
+- shared libraries, user space kernel data, shared memory, and
+- memory mapped files.
+-
+- FLAGS is a string of single bit flags represented by the following
+- macros. They tell `mlockall' which of its functions you want. All
+- other bits must be zero.
+-
+- `MCL_CURRENT'
+- Lock all pages which currently exist in the calling process'
+- virtual address space.
+-
+- `MCL_FUTURE'
+- Set a mode such that any pages added to the process' virtual
+- address space in the future will be locked from birth. This
+- mode does not affect future address spaces owned by the same
+- process so exec, which replaces a process' address space,
+- wipes out `MCL_FUTURE'. *Note Executing a File::.
+-
+- When the function returns successfully, and you specified
+- `MCL_CURRENT', all of the process' pages are backed by (connected
+- to) real frames (they are resident) and are marked to stay that
+- way. This means the function may cause page-ins and have to wait
+- for them.
+-
+- When the process is in `MCL_FUTURE' mode because it successfully
+- executed this function and specified `MCL_CURRENT', any system call
+- by the process that requires space be added to its virtual address
+- space fails with `errno' = `ENOMEM' if locking the additional space
+- would cause the process to exceed its locked page limit. In the
+- case that the address space addition that can't be accommodated is
+- stack expansion, the stack expansion fails and the kernel sends a
+- `SIGSEGV' signal to the process.
+-
+- When the function fails, it does not affect the lock status of any
+- pages or the future locking mode.
+-
+- The return value is zero if the function succeeds. Otherwise, it
+- is `-1' and `errno' is set accordingly. `errno' values specific
+- to this function are:
+-
+- `ENOMEM'
+- * At least some of the specified address range does not
+- exist in the calling process' virtual address space.
+-
+- * The locking would cause the process to exceed its locked
+- page limit.
+-
+- `EPERM'
+- The calling process is not superuser.
+-
+- `EINVAL'
+- Undefined bits in FLAGS are not zero.
+-
+- `ENOSYS'
+- The kernel does not provide `mlockall' capability.
+-
+- You can lock just specific pages with `mlock'. You unlock pages
+- with `munlockall' and `munlock'.
+-
+-
+- - Function: int munlockall (void)
+- `munlockall' unlocks every page in the calling process' virtual
+- address space and turn off `MCL_FUTURE' future locking mode.
+-
+- The return value is zero if the function succeeds. Otherwise, it
+- is `-1' and `errno' is set accordingly. The only way this
+- function can fail is for generic reasons that all functions and
+- system calls can fail, so there are no specific `errno' values.

+-Character Handling
+-******************
+-
+- Programs that work with characters and strings often need to
+-classify a character--is it alphabetic, is it a digit, is it
+-whitespace, and so on--and perform case conversion operations on
+-characters. The functions in the header file `ctype.h' are provided
+-for this purpose.
+-
+- Since the choice of locale and character set can alter the
+-classifications of particular character codes, all of these functions
+-are affected by the current locale. (More precisely, they are affected
+-by the locale currently selected for character classification--the
+-`LC_CTYPE' category; see *Note Locale Categories::.)
+-
+- The ISO C standard specifies two different sets of functions. The
+-one set works on `char' type characters, the other one on `wchar_t'
+-wide characters (*note Extended Char Intro::).
+-
+-* Menu:
+-
+-* Classification of Characters:: Testing whether characters are
+- letters, digits, punctuation, etc.
+-
+-* Case Conversion:: Case mapping, and the like.
+-* Classification of Wide Characters:: Character class determination for
+- wide characters.
+-* Using Wide Char Classes:: Notes on using the wide character
+- classes.
+-* Wide Character Case Conversion:: Mapping of wide characters.

+-
+-Classification of Characters
+-============================
+-
+- This section explains the library functions for classifying
+-characters. For example, `isalpha' is the function to test for an
+-alphabetic character. It takes one argument, the character to test,
+-and returns a nonzero integer if the character is alphabetic, and zero
+-otherwise. You would use it like this:
+-
+- if (isalpha (c))
+- printf ("The character `%c' is alphabetic.\n", c);
+-
+- Each of the functions in this section tests for membership in a
+-particular class of characters; each has a name starting with `is'.
+-Each of them takes one argument, which is a character to test, and
+-returns an `int' which is treated as a boolean value. The character
+-argument is passed as an `int', and it may be the constant value `EOF'
+-instead of a real character.
+-
+- The attributes of any given character can vary between locales.
+-*Note Locales::, for more information on locales.
+-
+- These functions are declared in the header file `ctype.h'.
+-
+- - Function: int islower (int C)
+- Returns true if C is a lower-case letter. The letter need not be
+- from the Latin alphabet, any alphabet representable is valid.
+-
+- - Function: int isupper (int C)
+- Returns true if C is an upper-case letter. The letter need not be
+- from the Latin alphabet, any alphabet representable is valid.
+-
+- - Function: int isalpha (int C)
+- Returns true if C is an alphabetic character (a letter). If
+- `islower' or `isupper' is true of a character, then `isalpha' is
+- also true.
+-
+- In some locales, there may be additional characters for which
+- `isalpha' is true--letters which are neither upper case nor lower
+- case. But in the standard `"C"' locale, there are no such
+- additional characters.
+-
+- - Function: int isdigit (int C)
+- Returns true if C is a decimal digit (`0' through `9').
+-
+- - Function: int isalnum (int C)
+- Returns true if C is an alphanumeric character (a letter or
+- number); in other words, if either `isalpha' or `isdigit' is true
+- of a character, then `isalnum' is also true.
+-
+- - Function: int isxdigit (int C)
+- Returns true if C is a hexadecimal digit. Hexadecimal digits
+- include the normal decimal digits `0' through `9' and the letters
+- `A' through `F' and `a' through `f'.
+-
+- - Function: int ispunct (int C)
+- Returns true if C is a punctuation character. This means any
+- printing character that is not alphanumeric or a space character.
+-
+- - Function: int isspace (int C)
+- Returns true if C is a "whitespace" character. In the standard
+- `"C"' locale, `isspace' returns true for only the standard
+- whitespace characters:
+-
+- `' ''
+- space
+-
+- `'\f''
+- formfeed
+-
+- `'\n''
+- newline
+-
+- `'\r''
+- carriage return
+-
+- `'\t''
+- horizontal tab
+-
+- `'\v''
+- vertical tab
+-
+- - Function: int isblank (int C)
+- Returns true if C is a blank character; that is, a space or a tab.
+- This function is a GNU extension.
+-
+- - Function: int isgraph (int C)
+- Returns true if C is a graphic character; that is, a character
+- that has a glyph associated with it. The whitespace characters
+- are not considered graphic.
+-
+- - Function: int isprint (int C)
+- Returns true if C is a printing character. Printing characters
+- include all the graphic characters, plus the space (` ') character.
+-
+- - Function: int iscntrl (int C)
+- Returns true if C is a control character (that is, a character that
+- is not a printing character).
+-
+- - Function: int isascii (int C)
+- Returns true if C is a 7-bit `unsigned char' value that fits into
+- the US/UK ASCII character set. This function is a BSD extension
+- and is also an SVID extension.

+-Case Conversion
+-===============
+-
+- This section explains the library functions for performing
+-conversions such as case mappings on characters. For example, `toupper'
+-converts any character to upper case if possible. If the character
+-can't be converted, `toupper' returns it unchanged.
+-
+- These functions take one argument of type `int', which is the
+-character to convert, and return the converted character as an `int'.
+-If the conversion is not applicable to the argument given, the argument
+-is returned unchanged.
+-
+- *Compatibility Note:* In pre-ISO C dialects, instead of returning
+-the argument unchanged, these functions may fail when the argument is
+-not suitable for the conversion. Thus for portability, you may need to
+-write `islower(c) ? toupper(c) : c' rather than just `toupper(c)'.
+-
+- These functions are declared in the header file `ctype.h'.
+-
+- - Function: int tolower (int C)
+- If C is an upper-case letter, `tolower' returns the corresponding
+- lower-case letter. If C is not an upper-case letter, C is
+- returned unchanged.
+-
+- - Function: int toupper (int C)
+- If C is a lower-case letter, `toupper' returns the corresponding
+- upper-case letter. Otherwise C is returned unchanged.
+-
+- - Function: int toascii (int C)
+- This function converts C to a 7-bit `unsigned char' value that
+- fits into the US/UK ASCII character set, by clearing the high-order
+- bits. This function is a BSD extension and is also an SVID
+- extension.
+-
+- - Function: int _tolower (int C)
+- This is identical to `tolower', and is provided for compatibility
+- with the SVID. *Note SVID::.
+-
+- - Function: int _toupper (int C)
+- This is identical to `toupper', and is provided for compatibility
+- with the SVID.

+-
+-Basic Thread Operations
+-=======================
+-
+- These functions are the thread equivalents of `fork', `exit', and
+-`wait'.
+-
+- - Function: int pthread_create (pthread_t * THREAD, pthread_attr_t *
+- ATTR, void * (*START_ROUTINE)(void *), void * ARG)
+- `pthread_create' creates a new thread of control that executes
+- concurrently with the calling thread. The new thread calls the
+- function START_ROUTINE, passing it ARG as first argument. The new
+- thread terminates either explicitly, by calling `pthread_exit', or
+- implicitly, by returning from the START_ROUTINE function. The
+- latter case is equivalent to calling `pthread_exit' with the result
+- returned by START_ROUTINE as exit code.
+-
+- The ATTR argument specifies thread attributes to be applied to the
+- new thread. *Note Thread Attributes::, for details. The ATTR
+- argument can also be `NULL', in which case default attributes are
+- used: the created thread is joinable (not detached) and has an
+- ordinary (not realtime) scheduling policy.
+-
+- On success, the identifier of the newly created thread is stored
+- in the location pointed by the THREAD argument, and a 0 is
+- returned. On error, a non-zero error code is returned.
+-
+- This function may return the following errors:
+- `EAGAIN'
+- Not enough system resources to create a process for the new
+- thread, or more than `PTHREAD_THREADS_MAX' threads are
+- already active.
+-
+- - Function: void pthread_exit (void *RETVAL)
+- `pthread_exit' terminates the execution of the calling thread. All
+- cleanup handlers (*note Cleanup Handlers::) that have been set for
+- the calling thread with `pthread_cleanup_push' are executed in
+- reverse order (the most recently pushed handler is executed
+- first). Finalization functions for thread-specific data are then
+- called for all keys that have non-`NULL' values associated with
+- them in the calling thread (*note Thread-Specific Data::).
+- Finally, execution of the calling thread is stopped.
+-
+- The RETVAL argument is the return value of the thread. It can be
+- retrieved from another thread using `pthread_join'.
+-
+- The `pthread_exit' function never returns.
+-
+- - Function: int pthread_cancel (pthread_t THREAD)
+- `pthread_cancel' sends a cancellation request to the thread denoted
+- by the THREAD argument. If there is no such thread,
+- `pthread_cancel' fails and returns `ESRCH'. Otherwise it returns
+- 0. *Note Cancellation::, for details.
+-
+- - Function: int pthread_join (pthread_t TH, void **thread_RETURN)
+- `pthread_join' suspends the execution of the calling thread until
+- the thread identified by TH terminates, either by calling
+- `pthread_exit' or by being canceled.
+-
+- If THREAD_RETURN is not `NULL', the return value of TH is stored
+- in the location pointed to by THREAD_RETURN. The return value of
+- TH is either the argument it gave to `pthread_exit', or
+- `PTHREAD_CANCELED' if TH was canceled.
+-
+- The joined thread `th' must be in the joinable state: it must not
+- have been detached using `pthread_detach' or the
+- `PTHREAD_CREATE_DETACHED' attribute to `pthread_create'.
+-
+- When a joinable thread terminates, its memory resources (thread
+- descriptor and stack) are not deallocated until another thread
+- performs `pthread_join' on it. Therefore, `pthread_join' must be
+- called once for each joinable thread created to avoid memory leaks.
+-
+- At most one thread can wait for the termination of a given thread.
+- Calling `pthread_join' on a thread TH on which another thread is
+- already waiting for termination returns an error.
+-
+- `pthread_join' is a cancellation point. If a thread is canceled
+- while suspended in `pthread_join', the thread execution resumes
+- immediately and the cancellation is executed without waiting for
+- the TH thread to terminate. If cancellation occurs during
+- `pthread_join', the TH thread remains not joined.
+-
+- On success, the return value of TH is stored in the location
+- pointed to by THREAD_RETURN, and 0 is returned. On error, one of
+- the following values is returned:
+- `ESRCH'
+- No thread could be found corresponding to that specified by
+- TH.
+-
+- `EINVAL'
+- The TH thread has been detached, or another thread is already
+- waiting on termination of TH.
+-
+- `EDEADLK'
+- The TH argument refers to the calling thread.

+-
+-Thread Attributes
+-=================
+-
+- Threads have a number of attributes that may be set at creation time.
+-This is done by filling a thread attribute object ATTR of type
+-`pthread_attr_t', then passing it as second argument to
+-`pthread_create'. Passing `NULL' is equivalent to passing a thread
+-attribute object with all attributes set to their default values.
+-
+- Attribute objects are consulted only when creating a new thread. The
+-same attribute object can be used for creating several threads.
+-Modifying an attribute object after a call to `pthread_create' does not
+-change the attributes of the thread previously created.
+-
+- - Function: int pthread_attr_init (pthread_attr_t *ATTR)
+- `pthread_attr_init' initializes the thread attribute object ATTR
+- and fills it with default values for the attributes. (The default
+- values are listed below for each attribute.)
+-
+- Each attribute ATTRNAME (see below for a list of all attributes)
+- can be individually set using the function
+- `pthread_attr_setATTRNAME' and retrieved using the function
+- `pthread_attr_getATTRNAME'.
+-
+- - Function: int pthread_attr_destroy (pthread_attr_t *ATTR)
+- `pthread_attr_destroy' destroys the attribute object pointed to by
+- ATTR releasing any resources associated with it. ATTR is left in
+- an undefined state, and you must not use it again in a call to any
+- pthreads function until it has been reinitialized.
+-
+- - Function: int pthread_attr_setattr (pthread_attr_t *OBJ, int VALUE)
+- Set attribute ATTR to VALUE in the attribute object pointed to by
+- OBJ. See below for a list of possible attributes and the values
+- they can take.
+-
+- On success, these functions return 0. If VALUE is not meaningful
+- for the ATTR being modified, they will return the error code
+- `EINVAL'. Some of the functions have other failure modes; see
+- below.
+-
+- - Function: int pthread_attr_getattr (const pthread_attr_t *OBJ, int
+- *VALUE)
+- Store the current setting of ATTR in OBJ into the variable pointed
+- to by VALUE.
+-
+- These functions always return 0.
+-
+- The following thread attributes are supported:
+-`detachstate'
+- Choose whether the thread is created in the joinable state (value
+- `PTHREAD_CREATE_JOINABLE') or in the detached state
+- (`PTHREAD_CREATE_DETACHED'). The default is
+- `PTHREAD_CREATE_JOINABLE'.
+-
+- In the joinable state, another thread can synchronize on the thread
+- termination and recover its termination code using `pthread_join',
+- but some of the thread resources are kept allocated after the
+- thread terminates, and reclaimed only when another thread performs
+- `pthread_join' on that thread.
+-
+- In the detached state, the thread resources are immediately freed
+- when it terminates, but `pthread_join' cannot be used to
+- synchronize on the thread termination.
+-
+- A thread created in the joinable state can later be put in the
+- detached thread using `pthread_detach'.
+-
+-`schedpolicy'
+- Select the scheduling policy for the thread: one of `SCHED_OTHER'
+- (regular, non-realtime scheduling), `SCHED_RR' (realtime,
+- round-robin) or `SCHED_FIFO' (realtime, first-in first-out). The
+- default is `SCHED_OTHER'.
+-
+- The realtime scheduling policies `SCHED_RR' and `SCHED_FIFO' are
+- available only to processes with superuser privileges.
+- `pthread_attr_setschedparam' will fail and return `ENOTSUP' if you
+- try to set a realtime policy when you are unprivileged.
+-
+- The scheduling policy of a thread can be changed after creation
+- with `pthread_setschedparam'.
+-
+-`schedparam'
+- Change the scheduling parameter (the scheduling priority) for the
+- thread. The default is 0.
+-
+- This attribute is not significant if the scheduling policy is
+- `SCHED_OTHER'; it only matters for the realtime policies
+- `SCHED_RR' and `SCHED_FIFO'.
+-
+- The scheduling priority of a thread can be changed after creation
+- with `pthread_setschedparam'.
+-
+-`inheritsched'
+- Choose whether the scheduling policy and scheduling parameter for
+- the newly created thread are determined by the values of the
+- SCHEDPOLICY and SCHEDPARAM attributes (value
+- `PTHREAD_EXPLICIT_SCHED') or are inherited from the parent thread
+- (value `PTHREAD_INHERIT_SCHED'). The default is
+- `PTHREAD_EXPLICIT_SCHED'.
+-
+-`scope'
+- Choose the scheduling contention scope for the created thread. The
+- default is `PTHREAD_SCOPE_SYSTEM', meaning that the threads contend
+- for CPU time with all processes running on the machine. In
+- particular, thread priorities are interpreted relative to the
+- priorities of all other processes on the machine. The other
+- possibility, `PTHREAD_SCOPE_PROCESS', means that scheduling
+- contention occurs only between the threads of the running process:
+- thread priorities are interpreted relative to the priorities of
+- the other threads of the process, regardless of the priorities of
+- other processes.
+-
+- `PTHREAD_SCOPE_PROCESS' is not supported in LinuxThreads. If you
+- try to set the scope to this value, `pthread_attr_setscope' will
+- fail and return `ENOTSUP'.
+-
+-`stackaddr'
+- Provide an address for an application managed stack. The size of
+- the stack must be at least `PTHREAD_STACK_MIN'.
+-
+-`stacksize'
+- Change the size of the stack created for the thread. The value
+- defines the minimum stack size, in bytes.
+-
+- If the value exceeds the system's maximum stack size, or is smaller
+- than `PTHREAD_STACK_MIN', `pthread_attr_setstacksize' will fail
+- and return `EINVAL'.
+-
+-`stack'
+- Provide both the address and size of an application managed stack
+- to use for the new thread. The base of the memory area is
+- STACKADDR with the size of the memory area, STACKSIZE, measured in
+- bytes.
+-
+- If the value of STACKSIZE is less than `PTHREAD_STACK_MIN', or
+- greater than the system's maximum stack size, or if the value of
+- STACKADDR lacks the proper alignment, `pthread_attr_setstack' will
+- fail and return `EINVAL'.
+-
+-`guardsize'
+- Change the minimum size in bytes of the guard area for the thread's
+- stack. The default size is a single page. If this value is set,
+- it will be rounded up to the nearest page size. If the value is
+- set to 0, a guard area will not be created for this thread. The
+- space allocated for the guard area is used to catch stack
+- overflow. Therefore, when allocating large structures on the
+- stack, a larger guard area may be required to catch a stack
+- overflow.
+-
+- If the caller is managing their own stacks (if the `stackaddr'
+- attribute has been set), then the `guardsize' attribute is ignored.
+-
+- If the value exceeds the `stacksize', `pthread_atrr_setguardsize'
+- will fail and return `EINVAL'.

+-
+-Cancellation
+-============
+-
+- Cancellation is the mechanism by which a thread can terminate the
+-execution of another thread. More precisely, a thread can send a
+-cancellation request to another thread. Depending on its settings, the
+-target thread can then either ignore the request, honor it immediately,
+-or defer it till it reaches a cancellation point. When threads are
+-first created by `pthread_create', they always defer cancellation
+-requests.
+-
+- When a thread eventually honors a cancellation request, it behaves
+-as if `pthread_exit(PTHREAD_CANCELED)' was called. All cleanup handlers
+-are executed in reverse order, finalization functions for
+-thread-specific data are called, and finally the thread stops executing.
+-If the canceled thread was joinable, the return value
+-`PTHREAD_CANCELED' is provided to whichever thread calls PTHREAD_JOIN
+-on it. See `pthread_exit' for more information.
+-
+- Cancellation points are the points where the thread checks for
+-pending cancellation requests and performs them. The POSIX threads
+-functions `pthread_join', `pthread_cond_wait',
+-`pthread_cond_timedwait', `pthread_testcancel', `sem_wait', and
+-`sigwait' are cancellation points. In addition, these system calls are
+-cancellation points:

+-Cleanup Handlers
+-================
+-
+- Cleanup handlers are functions that get called when a thread
+-terminates, either by calling `pthread_exit' or because of
+-cancellation. Cleanup handlers are installed and removed following a
+-stack-like discipline.
+-
+- The purpose of cleanup handlers is to free the resources that a
+-thread may hold at the time it terminates. In particular, if a thread
+-exits or is canceled while it owns a locked mutex, the mutex will
+-remain locked forever and prevent other threads from executing
+-normally. The best way to avoid this is, just before locking the mutex,
+-to install a cleanup handler whose effect is to unlock the mutex.
+-Cleanup handlers can be used similarly to free blocks allocated with
+-`malloc' or close file descriptors on thread termination.
+-
+- Here is how to lock a mutex MUT in such a way that it will be
+-unlocked if the thread is canceled while MUT is locked:
+-
+- pthread_cleanup_push(pthread_mutex_unlock, (void *) &mut);
+- pthread_mutex_lock(&mut);
+- /* do some work */
+- pthread_mutex_unlock(&mut);
+- pthread_cleanup_pop(0);
+-
+- Equivalently, the last two lines can be replaced by
+-
+- pthread_cleanup_pop(1);
+-
+- Notice that the code above is safe only in deferred cancellation mode
+-(see `pthread_setcanceltype'). In asynchronous cancellation mode, a
+-cancellation can occur between `pthread_cleanup_push' and
+-`pthread_mutex_lock', or between `pthread_mutex_unlock' and
+-`pthread_cleanup_pop', resulting in both cases in the thread trying to
+-unlock a mutex not locked by the current thread. This is the main
+-reason why asynchronous cancellation is difficult to use.
+-
+- If the code above must also work in asynchronous cancellation mode,
+-then it must switch to deferred mode for locking and unlocking the
+-mutex:
+-
+- pthread_setcanceltype(PTHREAD_CANCEL_DEFERRED, &oldtype);
+- pthread_cleanup_push(pthread_mutex_unlock, (void *) &mut);
+- pthread_mutex_lock(&mut);
+- /* do some work */
+- pthread_cleanup_pop(1);
+- pthread_setcanceltype(oldtype, NULL);
+-
+- The code above can be rewritten in a more compact and efficient way,
+-using the non-portable functions `pthread_cleanup_push_defer_np' and
+-`pthread_cleanup_pop_restore_np':
+-
+- pthread_cleanup_push_defer_np(pthread_mutex_unlock, (void *) &mut);
+- pthread_mutex_lock(&mut);
+- /* do some work */
+- pthread_cleanup_pop_restore_np(1);
+-
+- - Function: void pthread_cleanup_push (void (*ROUTINE) (void *), void
+- *ARG)
+- `pthread_cleanup_push' installs the ROUTINE function with argument
+- ARG as a cleanup handler. From this point on to the matching
+- `pthread_cleanup_pop', the function ROUTINE will be called with
+- arguments ARG when the thread terminates, either through
+- `pthread_exit' or by cancellation. If several cleanup handlers are
+- active at that point, they are called in LIFO order: the most
+- recently installed handler is called first.
+-
+- - Function: void pthread_cleanup_pop (int EXECUTE)
+- `pthread_cleanup_pop' removes the most recently installed cleanup
+- handler. If the EXECUTE argument is not 0, it also executes the
+- handler, by calling the ROUTINE function with arguments ARG. If
+- the EXECUTE argument is 0, the handler is only removed but not
+- executed.
+-
+- Matching pairs of `pthread_cleanup_push' and `pthread_cleanup_pop'
+-must occur in the same function, at the same level of block nesting.
+-Actually, `pthread_cleanup_push' and `pthread_cleanup_pop' are macros,
+-and the expansion of `pthread_cleanup_push' introduces an open brace
+-`{' with the matching closing brace `}' being introduced by the
+-expansion of the matching `pthread_cleanup_pop'.
+-
+- - Function: void pthread_cleanup_push_defer_np (void (*ROUTINE) (void
+- *), void *ARG)
+- `pthread_cleanup_push_defer_np' is a non-portable extension that
+- combines `pthread_cleanup_push' and `pthread_setcanceltype'. It
+- pushes a cleanup handler just as `pthread_cleanup_push' does, but
+- also saves the current cancellation type and sets it to deferred
+- cancellation. This ensures that the cleanup mechanism is effective
+- even if the thread was initially in asynchronous cancellation mode.
+-
+- - Function: void pthread_cleanup_pop_restore_np (int EXECUTE)
+- `pthread_cleanup_pop_restore_np' pops a cleanup handler introduced
+- by `pthread_cleanup_push_defer_np', and restores the cancellation
+- type to its value at the time `pthread_cleanup_push_defer_np' was
+- called.
+-
+- `pthread_cleanup_push_defer_np' and `pthread_cleanup_pop_restore_np'
+-must occur in matching pairs, at the same level of block nesting.
+-
+- The sequence
+-
+- pthread_cleanup_push_defer_np(routine, arg);
+- ...
+- pthread_cleanup_pop_defer_np(execute);
+-
+-is functionally equivalent to (but more compact and efficient than)
+-
+- {
+- int oldtype;
+- pthread_setcanceltype(PTHREAD_CANCEL_DEFERRED, &oldtype);
+- pthread_cleanup_push(routine, arg);

+- pthread_cleanup_pop(execute);

+-Mutexes
+-=======
+-
+- A mutex is a MUTual EXclusion device, and is useful for protecting
+-shared data structures from concurrent modifications, and implementing
+-critical sections and monitors.
+-
+- A mutex has two possible states: unlocked (not owned by any thread),
+-and locked (owned by one thread). A mutex can never be owned by two
+-different threads simultaneously. A thread attempting to lock a mutex
+-that is already locked by another thread is suspended until the owning
+-thread unlocks the mutex first.
+-
+- None of the mutex functions is a cancellation point, not even
+-`pthread_mutex_lock', in spite of the fact that it can suspend a thread
+-for arbitrary durations. This way, the status of mutexes at
+-cancellation points is predictable, allowing cancellation handlers to
+-unlock precisely those mutexes that need to be unlocked before the
+-thread stops executing. Consequently, threads using deferred
+-cancellation should never hold a mutex for extended periods of time.
+-
+- It is not safe to call mutex functions from a signal handler. In
+-particular, calling `pthread_mutex_lock' or `pthread_mutex_unlock' from
+-a signal handler may deadlock the calling thread.
+-
+- - Function: int pthread_mutex_init (pthread_mutex_t *MUTEX, const
+- pthread_mutexattr_t *MUTEXATTR)
+- `pthread_mutex_init' initializes the mutex object pointed to by
+- MUTEX according to the mutex attributes specified in MUTEXATTR.
+- If MUTEXATTR is `NULL', default attributes are used instead.
+-
+- The LinuxThreads implementation supports only one mutex attribute,
+- the MUTEX TYPE, which is either "fast", "recursive", or "error
+- checking". The type of a mutex determines whether it can be locked
+- again by a thread that already owns it. The default type is
+- "fast".
+-
+- Variables of type `pthread_mutex_t' can also be initialized
+- statically, using the constants `PTHREAD_MUTEX_INITIALIZER' (for
+- timed mutexes), `PTHREAD_RECURSIVE_MUTEX_INITIALIZER_NP' (for
+- recursive mutexes), `PTHREAD_ADAPTIVE_MUTEX_INITIALIZER_NP' (for
+- fast mutexes(, and `PTHREAD_ERRORCHECK_MUTEX_INITIALIZER_NP' (for
+- error checking mutexes).
+-
+- `pthread_mutex_init' always returns 0.
+-
+- - Function: int pthread_mutex_lock (pthread_mutex_t *mutex))
+- `pthread_mutex_lock' locks the given mutex. If the mutex is
+- currently unlocked, it becomes locked and owned by the calling
+- thread, and `pthread_mutex_lock' returns immediately. If the mutex
+- is already locked by another thread, `pthread_mutex_lock' suspends
+- the calling thread until the mutex is unlocked.
+-
+- If the mutex is already locked by the calling thread, the behavior
+- of `pthread_mutex_lock' depends on the type of the mutex. If the
+- mutex is of the "fast" type, the calling thread is suspended. It
+- will remain suspended forever, because no other thread can unlock
+- the mutex. If the mutex is of the "error checking" type,
+- `pthread_mutex_lock' returns immediately with the error code
+- `EDEADLK'. If the mutex is of the "recursive" type,
+- `pthread_mutex_lock' succeeds and returns immediately, recording
+- the number of times the calling thread has locked the mutex. An
+- equal number of `pthread_mutex_unlock' operations must be
+- performed before the mutex returns to the unlocked state.
+-
+- - Function: int pthread_mutex_trylock (pthread_mutex_t *MUTEX)
+- `pthread_mutex_trylock' behaves identically to
+- `pthread_mutex_lock', except that it does not block the calling
+- thread if the mutex is already locked by another thread (or by the
+- calling thread in the case of a "fast" mutex). Instead,
+- `pthread_mutex_trylock' returns immediately with the error code
+- `EBUSY'.
+-
+- - Function: int pthread_mutex_timedlock (pthread_mutex_t *MUTEX, const
+- struct timespec *ABSTIME)
+- The `pthread_mutex_timedlock' is similar to the
+- `pthread_mutex_lock' function but instead of blocking for in
+- indefinite time if the mutex is locked by another thread, it
+- returns when the time specified in ABSTIME is reached.
+-
+- This function can only be used on standard ("timed") and "error
+- checking" mutexes. It behaves just like `pthread_mutex_lock' for
+- all other types.
+-
+- If the mutex is successfully locked, the function returns zero.
+- If the time specified in ABSTIME is reached without the mutex
+- being locked, `ETIMEDOUT' is returned.
+-
+- This function was introduced in the POSIX.1d revision of the POSIX
+- standard.
+-
+- - Function: int pthread_mutex_unlock (pthread_mutex_t *MUTEX)
+- `pthread_mutex_unlock' unlocks the given mutex. The mutex is
+- assumed to be locked and owned by the calling thread on entrance to
+- `pthread_mutex_unlock'. If the mutex is of the "fast" type,
+- `pthread_mutex_unlock' always returns it to the unlocked state. If
+- it is of the "recursive" type, it decrements the locking count of
+- the mutex (number of `pthread_mutex_lock' operations performed on
+- it by the calling thread), and only when this count reaches zero
+- is the mutex actually unlocked.
+-
+- On "error checking" mutexes, `pthread_mutex_unlock' actually
+- checks at run-time that the mutex is locked on entrance, and that
+- it was locked by the same thread that is now calling
+- `pthread_mutex_unlock'. If these conditions are not met,
+- `pthread_mutex_unlock' returns `EPERM', and the mutex remains
+- unchanged. "Fast" and "recursive" mutexes perform no such checks,
+- thus allowing a locked mutex to be unlocked by a thread other than
+- its owner. This is non-portable behavior and must not be relied
+- upon.
+-
+- - Function: int pthread_mutex_destroy (pthread_mutex_t *MUTEX)
+- `pthread_mutex_destroy' destroys a mutex object, freeing the
+- resources it might hold. The mutex must be unlocked on entrance.
+- In the LinuxThreads implementation, no resources are associated
+- with mutex objects, thus `pthread_mutex_destroy' actually does
+- nothing except checking that the mutex is unlocked.
+-
+- If the mutex is locked by some thread, `pthread_mutex_destroy'
+- returns `EBUSY'. Otherwise it returns 0.
+-
+- If any of the above functions (except `pthread_mutex_init') is
+-applied to an uninitialized mutex, they will simply return `EINVAL' and
+-do nothing.
+-
+- A shared global variable X can be protected by a mutex as follows:
+-
+- int x;
+- pthread_mutex_t mut = PTHREAD_MUTEX_INITIALIZER;
+-
+- All accesses and modifications to X should be bracketed by calls to
+-`pthread_mutex_lock' and `pthread_mutex_unlock' as follows:
+-
+- pthread_mutex_lock(&mut);
+- /* operate on x */
+- pthread_mutex_unlock(&mut);
+-
+- Mutex attributes can be specified at mutex creation time, by passing
+-a mutex attribute object as second argument to `pthread_mutex_init'.
+-Passing `NULL' is equivalent to passing a mutex attribute object with
+-all attributes set to their default values.
+-
+- - Function: int pthread_mutexattr_init (pthread_mutexattr_t *ATTR)
+- `pthread_mutexattr_init' initializes the mutex attribute object
+- ATTR and fills it with default values for the attributes.
+-
+- This function always returns 0.
+-
+- - Function: int pthread_mutexattr_destroy (pthread_mutexattr_t *ATTR)
+- `pthread_mutexattr_destroy' destroys a mutex attribute object,
+- which must not be reused until it is reinitialized.
+- `pthread_mutexattr_destroy' does nothing in the LinuxThreads
+- implementation.
+-
+- This function always returns 0.
+-
+- LinuxThreads supports only one mutex attribute: the mutex type,
+-which is either `PTHREAD_MUTEX_ADAPTIVE_NP' for "fast" mutexes,
+-`PTHREAD_MUTEX_RECURSIVE_NP' for "recursive" mutexes,
+-`PTHREAD_MUTEX_TIMED_NP' for "timed" mutexes, or
+-`PTHREAD_MUTEX_ERRORCHECK_NP' for "error checking" mutexes. As the
+-`NP' suffix indicates, this is a non-portable extension to the POSIX
+-standard and should not be employed in portable programs.
+-
+- The mutex type determines what happens if a thread attempts to lock a
+-mutex it already owns with `pthread_mutex_lock'. If the mutex is of the
+-"fast" type, `pthread_mutex_lock' simply suspends the calling thread
+-forever. If the mutex is of the "error checking" type,
+-`pthread_mutex_lock' returns immediately with the error code `EDEADLK'.
+-If the mutex is of the "recursive" type, the call to
+-`pthread_mutex_lock' returns immediately with a success return code.
+-The number of times the thread owning the mutex has locked it is
+-recorded in the mutex. The owning thread must call
+-`pthread_mutex_unlock' the same number of times before the mutex
+-returns to the unlocked state.
+-
+- The default mutex type is "timed", that is, `PTHREAD_MUTEX_TIMED_NP'.
+-
+- - Function: int pthread_mutexattr_settype (pthread_mutexattr_t *ATTR,
+- int TYPE)
+- `pthread_mutexattr_settype' sets the mutex type attribute in ATTR
+- to the value specified by TYPE.
+-
+- If TYPE is not `PTHREAD_MUTEX_ADAPTIVE_NP',
+- `PTHREAD_MUTEX_RECURSIVE_NP', `PTHREAD_MUTEX_TIMED_NP', or
+- `PTHREAD_MUTEX_ERRORCHECK_NP', this function will return `EINVAL'
+- and leave ATTR unchanged.
+-
+- The standard Unix98 identifiers `PTHREAD_MUTEX_DEFAULT',
+- `PTHREAD_MUTEX_NORMAL', `PTHREAD_MUTEX_RECURSIVE', and
+- `PTHREAD_MUTEX_ERRORCHECK' are also permitted.
+-
+-
+- - Function: int pthread_mutexattr_gettype (const pthread_mutexattr_t
+- *ATTR, int *TYPE)
+- `pthread_mutexattr_gettype' retrieves the current value of the
+- mutex type attribute in ATTR and stores it in the location pointed
+- to by TYPE.
+-
+- This function always returns 0.

+-Condition Variables
+-===================
+-
+- A condition (short for "condition variable") is a synchronization
+-device that allows threads to suspend execution until some predicate on
+-shared data is satisfied. The basic operations on conditions are: signal
+-the condition (when the predicate becomes true), and wait for the
+-condition, suspending the thread execution until another thread signals
+-the condition.
+-
+- A condition variable must always be associated with a mutex, to avoid
+-the race condition where a thread prepares to wait on a condition
+-variable and another thread signals the condition just before the first
+-thread actually waits on it.
+-
+- - Function: int pthread_cond_init (pthread_cond_t *COND,
+- pthread_condattr_t *cond_ATTR)
+- `pthread_cond_init' initializes the condition variable COND, using
+- the condition attributes specified in COND_ATTR, or default
+- attributes if COND_ATTR is `NULL'. The LinuxThreads implementation
+- supports no attributes for conditions, hence the COND_ATTR
+- parameter is actually ignored.
+-
+- Variables of type `pthread_cond_t' can also be initialized
+- statically, using the constant `PTHREAD_COND_INITIALIZER'.
+-
+- This function always returns 0.
+-
+- - Function: int pthread_cond_signal (pthread_cond_t *COND)
+- `pthread_cond_signal' restarts one of the threads that are waiting
+- on the condition variable COND. If no threads are waiting on COND,
+- nothing happens. If several threads are waiting on COND, exactly
+- one is restarted, but it is not specified which.
+-
+- This function always returns 0.
+-
+- - Function: int pthread_cond_broadcast (pthread_cond_t *COND)
+- `pthread_cond_broadcast' restarts all the threads that are waiting
+- on the condition variable COND. Nothing happens if no threads are
+- waiting on COND.
+-
+- This function always returns 0.
+-
+- - Function: int pthread_cond_wait (pthread_cond_t *COND,
+- pthread_mutex_t *MUTEX)
+- `pthread_cond_wait' atomically unlocks the MUTEX (as per
+- `pthread_unlock_mutex') and waits for the condition variable COND
+- to be signaled. The thread execution is suspended and does not
+- consume any CPU time until the condition variable is signaled. The
+- MUTEX must be locked by the calling thread on entrance to
+- `pthread_cond_wait'. Before returning to the calling thread,
+- `pthread_cond_wait' re-acquires MUTEX (as per
+- `pthread_lock_mutex').
+-
+- Unlocking the mutex and suspending on the condition variable is
+- done atomically. Thus, if all threads always acquire the mutex
+- before signaling the condition, this guarantees that the condition
+- cannot be signaled (and thus ignored) between the time a thread
+- locks the mutex and the time it waits on the condition variable.
+-
+- This function always returns 0.
+-
+- - Function: int pthread_cond_timedwait (pthread_cond_t *COND,
+- pthread_mutex_t *MUTEX, const struct timespec *ABSTIME)
+- `pthread_cond_timedwait' atomically unlocks MUTEX and waits on
+- COND, as `pthread_cond_wait' does, but it also bounds the duration
+- of the wait. If COND has not been signaled before time ABSTIME,
+- the mutex MUTEX is re-acquired and `pthread_cond_timedwait'
+- returns the error code `ETIMEDOUT'. The wait can also be
+- interrupted by a signal; in that case `pthread_cond_timedwait'
+- returns `EINTR'.
+-
+- The ABSTIME parameter specifies an absolute time, with the same
+- origin as `time' and `gettimeofday': an ABSTIME of 0 corresponds
+- to 00:00:00 GMT, January 1, 1970.
+-
+- - Function: int pthread_cond_destroy (pthread_cond_t *COND)
+- `pthread_cond_destroy' destroys the condition variable COND,
+- freeing the resources it might hold. If any threads are waiting
+- on the condition variable, `pthread_cond_destroy' leaves COND
+- untouched and returns `EBUSY'. Otherwise it returns 0, and COND
+- must not be used again until it is reinitialized.
+-
+- In the LinuxThreads implementation, no resources are associated
+- with condition variables, so `pthread_cond_destroy' actually does
+- nothing.
+-
+- `pthread_cond_wait' and `pthread_cond_timedwait' are cancellation
+-points. If a thread is canceled while suspended in one of these
+-functions, the thread immediately resumes execution, relocks the mutex
+-specified by MUTEX, and finally executes the cancellation.
+-Consequently, cleanup handlers are assured that MUTEX is locked when
+-they are called.
+-
+- It is not safe to call the condition variable functions from a signal
+-handler. In particular, calling `pthread_cond_signal' or
+-`pthread_cond_broadcast' from a signal handler may deadlock the calling
+-thread.
+-
+- Consider two shared variables X and Y, protected by the mutex MUT,
+-and a condition variable COND that is to be signaled whenever X becomes
+-greater than Y.
+-
+- int x,y;
+- pthread_mutex_t mut = PTHREAD_MUTEX_INITIALIZER;
+- pthread_cond_t cond = PTHREAD_COND_INITIALIZER;
+-
+- Waiting until X is greater than Y is performed as follows:
+-
+- pthread_mutex_lock(&mut);
+- while (x <= y) {
+- pthread_cond_wait(&cond, &mut);
+- }
+- /* operate on x and y */
+- pthread_mutex_unlock(&mut);
+-
+- Modifications on X and Y that may cause X to become greater than Y
+-should signal the condition if needed:
+-
+- pthread_mutex_lock(&mut);
+- /* modify x and y */
+- if (x > y) pthread_cond_broadcast(&cond);
+- pthread_mutex_unlock(&mut);
+-
+- If it can be proved that at most one waiting thread needs to be waken
+-up (for instance, if there are only two threads communicating through X
+-and Y), `pthread_cond_signal' can be used as a slightly more efficient
+-alternative to `pthread_cond_broadcast'. In doubt, use
+-`pthread_cond_broadcast'.
+-
+- To wait for X to becomes greater than Y with a timeout of 5 seconds,
+-do:
+-
+- struct timeval now;
+- struct timespec timeout;
+- int retcode;
+-
+- pthread_mutex_lock(&mut);
+- gettimeofday(&now);
+- timeout.tv_sec = now.tv_sec + 5;
+- timeout.tv_nsec = now.tv_usec * 1000;
+- retcode = 0;
+- while (x <= y && retcode != ETIMEDOUT) {
+- retcode = pthread_cond_timedwait(&cond, &mut, &timeout);
+- }
+- if (retcode == ETIMEDOUT) {
+- /* timeout occurred */
+- } else {
+- /* operate on x and y */
+- }
+- pthread_mutex_unlock(&mut);
+-
+- Condition attributes can be specified at condition creation time, by
+-passing a condition attribute object as second argument to
+-`pthread_cond_init'. Passing `NULL' is equivalent to passing a
+-condition attribute object with all attributes set to their default
+-values.
+-
+- The LinuxThreads implementation supports no attributes for

+-
+- - Function: int pthread_condattr_init (pthread_condattr_t *ATTR)

+-POSIX Semaphores
+-================
+-
+- Semaphores are counters for resources shared between threads. The
+-basic operations on semaphores are: increment the counter atomically,
+-and wait until the counter is non-null and decrement it atomically.
+-
+- Semaphores have a maximum value past which they cannot be
+-incremented. The macro `SEM_VALUE_MAX' is defined to be this maximum
+-value. In the GNU C library, `SEM_VALUE_MAX' is equal to `INT_MAX'
+-(*note Range of Type::), but it may be much smaller on other systems.
+-
+- The pthreads library implements POSIX 1003.1b semaphores. These
+-should not be confused with System V semaphores (`ipc', `semctl' and
+-`semop').
+-
+- All the semaphore functions and macros are defined in `semaphore.h'.
+-
+- - Function: int sem_init (sem_t *SEM, int PSHARED, unsigned int VALUE)
+- `sem_init' initializes the semaphore object pointed to by SEM. The
+- count associated with the semaphore is set initially to VALUE. The
+- PSHARED argument indicates whether the semaphore is local to the
+- current process (PSHARED is zero) or is to be shared between
+- several processes (PSHARED is not zero).
+-
+- On success `sem_init' returns 0. On failure it returns -1 and sets
+- ERRNO to one of the following values:
+-
+- `EINVAL'
+- VALUE exceeds the maximal counter value `SEM_VALUE_MAX'
+-
+- `ENOSYS'
+- PSHARED is not zero. LinuxThreads currently does not support
+- process-shared semaphores. (This will eventually change.)
+-
+- - Function: int sem_destroy (sem_t * SEM)
+- `sem_destroy' destroys a semaphore object, freeing the resources it
+- might hold. If any threads are waiting on the semaphore when
+- `sem_destroy' is called, it fails and sets ERRNO to `EBUSY'.
+-
+- In the LinuxThreads implementation, no resources are associated
+- with semaphore objects, thus `sem_destroy' actually does nothing
+- except checking that no thread is waiting on the semaphore. This
+- will change when process-shared semaphores are implemented.
+-
+- - Function: int sem_wait (sem_t * SEM)
+- `sem_wait' suspends the calling thread until the semaphore pointed
+- to by SEM has non-zero count. It then atomically decreases the
+- semaphore count.
+-
+- `sem_wait' is a cancellation point. It always returns 0.
+-
+- - Function: int sem_trywait (sem_t * SEM)
+- `sem_trywait' is a non-blocking variant of `sem_wait'. If the
+- semaphore pointed to by SEM has non-zero count, the count is
+- atomically decreased and `sem_trywait' immediately returns 0. If
+- the semaphore count is zero, `sem_trywait' immediately returns -1
+- and sets errno to `EAGAIN'.
+-
+- - Function: int sem_post (sem_t * SEM)
+- `sem_post' atomically increases the count of the semaphore pointed
+- to by SEM. This function never blocks.
+-
+- On processors supporting atomic compare-and-swap (Intel 486,
+- Pentium and later, Alpha, PowerPC, MIPS II, Motorola 68k,
+- Ultrasparc), the `sem_post' function is can safely be called from
+- signal handlers. This is the only thread synchronization function
+- provided by POSIX threads that is async-signal safe. On the Intel
+- 386 and earlier Sparc chips, the current LinuxThreads
+- implementation of `sem_post' is not async-signal safe, because the
+- hardware does not support the required atomic operations.
+-
+- `sem_post' always succeeds and returns 0, unless the semaphore
+- count would exceed `SEM_VALUE_MAX' after being incremented. In
+- that case `sem_post' returns -1 and sets ERRNO to `EINVAL'. The
+- semaphore count is left unchanged.
+-
+- - Function: int sem_getvalue (sem_t * SEM, int * SVAL)
+- `sem_getvalue' stores in the location pointed to by SVAL the
+- current count of the semaphore SEM. It always returns 0.

+-====================
+-
+- Programs often need global or static variables that have different
+-values in different threads. Since threads share one memory space, this
+-cannot be achieved with regular variables. Thread-specific data is the
+-POSIX threads answer to this need.
+-
+- Each thread possesses a private memory block, the thread-specific
+-data area, or TSD area for short. This area is indexed by TSD keys. The
+-TSD area associates values of type `void *' to TSD keys. TSD keys are
+-common to all threads, but the value associated with a given TSD key can
+-be different in each thread.
+-
+- For concreteness, the TSD areas can be viewed as arrays of `void *'
+-pointers, TSD keys as integer indices into these arrays, and the value
+-of a TSD key as the value of the corresponding array element in the
+-calling thread.
+-
+- When a thread is created, its TSD area initially associates `NULL'
+-with all keys.
+-
+- - Function: int pthread_key_create (pthread_key_t *KEY, void
+- (*destr_function) (void *))
+- `pthread_key_create' allocates a new TSD key. The key is stored in
+- the location pointed to by KEY. There is a limit of
+- `PTHREAD_KEYS_MAX' on the number of keys allocated at a given
+- time. The value initially associated with the returned key is
+- `NULL' in all currently executing threads.
+-
+- The DESTR_FUNCTION argument, if not `NULL', specifies a destructor
+- function associated with the key. When a thread terminates via
+- `pthread_exit' or by cancellation, DESTR_FUNCTION is called on the
+- value associated with the key in that thread. The DESTR_FUNCTION
+- is not called if a key is deleted with `pthread_key_delete' or a
+- value is changed with `pthread_setspecific'. The order in which
+- destructor functions are called at thread termination time is
+- unspecified.
+-
+- Before the destructor function is called, the `NULL' value is
+- associated with the key in the current thread. A destructor
+- function might, however, re-associate non-`NULL' values to that
+- key or some other key. To deal with this, if after all the
+- destructors have been called for all non-`NULL' values, there are
+- still some non-`NULL' values with associated destructors, then the
+- process is repeated. The LinuxThreads implementation stops the
+- process after `PTHREAD_DESTRUCTOR_ITERATIONS' iterations, even if
+- some non-`NULL' values with associated descriptors remain. Other
+- implementations may loop indefinitely.
+-
+- `pthread_key_create' returns 0 unless `PTHREAD_KEYS_MAX' keys have
+- already been allocated, in which case it fails and returns
+- `EAGAIN'.
+-
+- - Function: int pthread_key_delete (pthread_key_t KEY)
+- `pthread_key_delete' deallocates a TSD key. It does not check
+- whether non-`NULL' values are associated with that key in the
+- currently executing threads, nor call the destructor function
+- associated with the key.
+-
+- If there is no such key KEY, it returns `EINVAL'. Otherwise it
+- returns 0.
+-
+- - Function: int pthread_setspecific (pthread_key_t KEY, const void
+- *POINTER)
+- `pthread_setspecific' changes the value associated with KEY in the
+- calling thread, storing the given POINTER instead.
+-
+- If there is no such key KEY, it returns `EINVAL'. Otherwise it
+- returns 0.
+-
+- - Function: void * pthread_getspecific (pthread_key_t KEY)
+- `pthread_getspecific' returns the value currently associated with
+- KEY in the calling thread.
+-
+- If there is no such key KEY, it returns `NULL'.
+-
+- The following code fragment allocates a thread-specific array of 100
+-characters, with automatic reclaimation at thread exit:
+-
+- /* Key for the thread-specific buffer */
+- static pthread_key_t buffer_key;
+-
+- /* Once-only initialisation of the key */
+- static pthread_once_t buffer_key_once = PTHREAD_ONCE_INIT;
+-
+- /* Allocate the thread-specific buffer */
+- void buffer_alloc(void)
+- {
+- pthread_once(&buffer_key_once, buffer_key_alloc);
+- pthread_setspecific(buffer_key, malloc(100));
+- }
+-
+- /* Return the thread-specific buffer */
+- char * get_buffer(void)
+- {
+- return (char *) pthread_getspecific(buffer_key);
+- }
+-
+- /* Allocate the key */
+- static void buffer_key_alloc()
+- {
+- pthread_key_create(&buffer_key, buffer_destroy);
+- }
+-
+- /* Free the thread-specific buffer */
+- static void buffer_destroy(void * buf)
+- {
+- free(buf);
+- }

+-Threads and Signal Handling
+-===========================
+-
+- - Function: int pthread_sigmask (int HOW, const sigset_t *NEWMASK,
+- sigset_t *OLDMASK)
+- `pthread_sigmask' changes the signal mask for the calling thread as
+- described by the HOW and NEWMASK arguments. If OLDMASK is not
+- `NULL', the previous signal mask is stored in the location pointed
+- to by OLDMASK.
+-
+- The meaning of the HOW and NEWMASK arguments is the same as for
+- `sigprocmask'. If HOW is `SIG_SETMASK', the signal mask is set to
+- NEWMASK. If HOW is `SIG_BLOCK', the signals specified to NEWMASK
+- are added to the current signal mask. If HOW is `SIG_UNBLOCK',
+- the signals specified to NEWMASK are removed from the current
+- signal mask.
+-
+- Recall that signal masks are set on a per-thread basis, but signal
+- actions and signal handlers, as set with `sigaction', are shared
+- between all threads.
+-
+- The `pthread_sigmask' function returns 0 on success, and one of the
+- following error codes on error:
+- `EINVAL'
+- HOW is not one of `SIG_SETMASK', `SIG_BLOCK', or `SIG_UNBLOCK'
+-
+- `EFAULT'
+- NEWMASK or OLDMASK point to invalid addresses
+-
+- - Function: int pthread_kill (pthread_t THREAD, int SIGNO)
+- `pthread_kill' sends signal number SIGNO to the thread THREAD.
+- The signal is delivered and handled as described in *Note Signal
+- Handling::.
+-
+- `pthread_kill' returns 0 on success, one of the following error
+- codes on error:
+- `EINVAL'
+- SIGNO is not a valid signal number
+-
+- `ESRCH'
+- The thread THREAD does not exist (e.g. it has already
+- terminated)
+-
+- - Function: int sigwait (const sigset_t *SET, int *SIG)
+- `sigwait' suspends the calling thread until one of the signals in
+- SET is delivered to the calling thread. It then stores the number
+- of the signal received in the location pointed to by SIG and
+- returns. The signals in SET must be blocked and not ignored on
+- entrance to `sigwait'. If the delivered signal has a signal handler
+- function attached, that function is _not_ called.
+-
+- `sigwait' is a cancellation point. It always returns 0.
+-
+- For `sigwait' to work reliably, the signals being waited for must be
+-blocked in all threads, not only in the calling thread, since otherwise
+-the POSIX semantics for signal delivery do not guarantee that it's the
+-thread doing the `sigwait' that will receive the signal. The best way
+-to achieve this is block those signals before any threads are created,
+-and never unblock them in the program other than by calling `sigwait'.
+-
+- Signal handling in LinuxThreads departs significantly from the POSIX
+-standard. According to the standard, "asynchronous" (external) signals
+-are addressed to the whole process (the collection of all threads),
+-which then delivers them to one particular thread. The thread that
+-actually receives the signal is any thread that does not currently block
+-the signal.
+-
+- In LinuxThreads, each thread is actually a kernel process with its
+-own PID, so external signals are always directed to one particular
+-thread. If, for instance, another thread is blocked in `sigwait' on
+-that signal, it will not be restarted.
+-
+- The LinuxThreads implementation of `sigwait' installs dummy signal
+-handlers for the signals in SET for the duration of the wait. Since
+-signal handlers are shared between all threads, other threads must not
+-attach their own signal handlers to these signals, or alternatively
+-they should all block these signals (which is recommended anyway).

+-
+-Threads and Fork
+-================
+-
+- It's not intuitively obvious what should happen when a
+-multi-threaded POSIX process calls `fork'. Not only are the semantics
+-tricky, but you may need to write code that does the right thing at
+-fork time even if that code doesn't use the `fork' function. Moreover,
+-you need to be aware of interaction between `fork' and some library
+-features like `pthread_once' and stdio streams.
+-
+- When `fork' is called by one of the threads of a process, it creates
+-a new process which is copy of the calling process. Effectively, in
+-addition to copying certain system objects, the function takes a
+-snapshot of the memory areas of the parent process, and creates
+-identical areas in the child. To make matters more complicated, with
+-threads it's possible for two or more threads to concurrently call fork
+-to create two or more child processes.
+-
+- The child process has a copy of the address space of the parent, but
+-it does not inherit any of its threads. Execution of the child process
+-is carried out by a new thread which returns from `fork' function with
+-a return value of zero; it is the only thread in the child process.
+-Because threads are not inherited across fork, issues arise. At the
+-time of the call to `fork', threads in the parent process other than
+-the one calling `fork' may have been executing critical regions of
+-code. As a result, the child process may get a copy of objects that
+-are not in a well-defined state. This potential problem affects all
+-components of the program.
+-
+- Any program component which will continue being used in a child
+-process must correctly handle its state during `fork'. For this
+-purpose, the POSIX interface provides the special function
+-`pthread_atfork' for installing pointers to handler functions which are
+-called from within `fork'.
+-
+- - Function: int pthread_atfork (void (*PREPARE)(void), void
+- (*PARENT)(void), void (*CHILD)(void))
+- `pthread_atfork' registers handler functions to be called just
+- before and just after a new process is created with `fork'. The
+- PREPARE handler will be called from the parent process, just
+- before the new process is created. The PARENT handler will be
+- called from the parent process, just before `fork' returns. The
+- CHILD handler will be called from the child process, just before
+- `fork' returns.
+-
+- `pthread_atfork' returns 0 on success and a non-zero error code on
+- error.
+-
+- One or more of the three handlers PREPARE, PARENT and CHILD can be
+- given as `NULL', meaning that no handler needs to be called at the
+- corresponding point.
+-
+- `pthread_atfork' can be called several times to install several
+- sets of handlers. At `fork' time, the PREPARE handlers are called
+- in LIFO order (last added with `pthread_atfork', first called
+- before `fork'), while the PARENT and CHILD handlers are called in
+- FIFO order (first added, first called).
+-
+- If there is insufficient memory available to register the handlers,
+- `pthread_atfork' fails and returns `ENOMEM'. Otherwise it returns
+- 0.
+-
+- The functions `fork' and `pthread_atfork' must not be regarded as
+- reentrant from the context of the handlers. That is to say, if a
+- `pthread_atfork' handler invoked from within `fork' calls
+- `pthread_atfork' or `fork', the behavior is undefined.
+-
+- Registering a triplet of handlers is an atomic operation with
+- respect to fork. If new handlers are registered at about the same
+- time as a fork occurs, either all three handlers will be called,
+- or none of them will be called.
+-
+- The handlers are inherited by the child process, and there is no
+- way to remove them, short of using `exec' to load a new pocess
+- image.
+-
+-
+- To understand the purpose of `pthread_atfork', recall that `fork'
+-duplicates the whole memory space, including mutexes in their current
+-locking state, but only the calling thread: other threads are not
+-running in the child process. The mutexes are not usable after the
+-`fork' and must be initialized with `pthread_mutex_init' in the child
+-process. This is a limitation of the current implementation and might
+-or might not be present in future versions.
+-
+- To avoid this, install handlers with `pthread_atfork' as follows:
+-have the PREPARE handler lock the mutexes (in locking order), and the
+-PARENT handler unlock the mutexes. The CHILD handler should reset the
+-mutexes using `pthread_mutex_init', as well as any other
+-synchronization objects such as condition variables.
+-
+- Locking the global mutexes before the fork ensures that all other
+-threads are locked out of the critical regions of code protected by
+-those mutexes. Thus when `fork' takes a snapshot of the parent's
+-address space, that snapshot will copy valid, stable data. Resetting
+-the synchronization objects in the child process will ensure they are
+-properly cleansed of any artifacts from the threading subsystem of the
+-parent process. For example, a mutex may inherit a wait queue of
+-threads waiting for the lock; this wait queue makes no sense in the
+-child process. Initializing the mutex takes care of this.

+-
+-Streams and Fork
+-================
+-
+- The GNU standard I/O library has an internal mutex which guards the
+-internal linked list of all standard C FILE objects. This mutex is
+-properly taken care of during `fork' so that the child receives an
+-intact copy of the list. This allows the `fopen' function, and related
+-stream-creating functions, to work correctly in the child process,
+-since these functions need to insert into the list.
+-
+- However, the individual stream locks are not completely taken care
+-of. Thus unless the multithreaded application takes special
+-precautions in its use of `fork', the child process might not be able
+-to safely use the streams that it inherited from the parent. In
+-general, for any given open stream in the parent that is to be used by
+-the child process, the application must ensure that that stream is not
+-in use by another thread when `fork' is called. Otherwise an
+-inconsistent copy of the stream object be produced. An easy way to
+-ensure this is to use `flockfile' to lock the stream prior to calling
+-`fork' and then unlock it with `funlockfile' inside the parent process,
+-provided that the parent's threads properly honor these locks. Nothing
+-special needs to be done in the child process, since the library
+-internally resets all stream locks.
+-
+- Note that the stream locks are not shared between the parent and
+-child. For example, even if you ensure that, say, the stream `stdout'
+-is properly treated and can be safely used in the child, the stream
+-locks do not provide an exclusion mechanism between the parent and
+-child. If both processes write to `stdout', strangely interleaved
+-output may result regardless of the explicit use of `flockfile' or
+-implicit locks.
+-
+- Also note that these provisions are a GNU extension; other systems
+-might not provide any way for streams to be used in the child of a
+-multithreaded process. POSIX requires that such a child process
+-confines itself to calling only asynchronous safe functions, which
+-excludes much of the library, including standard I/O.

+-
+-Miscellaneous Thread Functions
+-==============================
+-
+- - Function: pthread_t pthread_self (VOID)
+- `pthread_self' returns the thread identifier for the calling
+- thread.
+-
+- - Function: int pthread_equal (pthread_t thread1, pthread_t thread2)
+- `pthread_equal' determines if two thread identifiers refer to the
+- same thread.
+-
+- A non-zero value is returned if THREAD1 and THREAD2 refer to the
+- same thread. Otherwise, 0 is returned.
+-
+- - Function: int pthread_detach (pthread_t TH)
+- `pthread_detach' puts the thread TH in the detached state. This
+- guarantees that the memory resources consumed by TH will be freed
+- immediately when TH terminates. However, this prevents other
+- threads from synchronizing on the termination of TH using
+- `pthread_join'.
+-
+- A thread can be created initially in the detached state, using the
+- `detachstate' attribute to `pthread_create'. In contrast,
+- `pthread_detach' applies to threads created in the joinable state,
+- and which need to be put in the detached state later.
+-
+- After `pthread_detach' completes, subsequent attempts to perform
+- `pthread_join' on TH will fail. If another thread is already
+- joining the thread TH at the time `pthread_detach' is called,
+- `pthread_detach' does nothing and leaves TH in the joinable state.
+-
+- On success, 0 is returned. On error, one of the following codes is
+- returned:
+- `ESRCH'
+- No thread could be found corresponding to that specified by TH
+-
+- `EINVAL'
+- The thread TH is already in the detached state
+-
+- - Function: void pthread_kill_other_threads_np (VOID)
+- `pthread_kill_other_threads_np' is a non-portable LinuxThreads
+- extension. It causes all threads in the program to terminate
+- immediately, except the calling thread which proceeds normally. It
+- is intended to be called just before a thread calls one of the
+- `exec' functions, e.g. `execve'.
+-
+- Termination of the other threads is not performed through
+- `pthread_cancel' and completely bypasses the cancellation
+- mechanism. Hence, the current settings for cancellation state and
+- cancellation type are ignored, and the cleanup handlers are not
+- executed in the terminated threads.
+-
+- According to POSIX 1003.1c, a successful `exec*' in one of the
+- threads should automatically terminate all other threads in the
+- program. This behavior is not yet implemented in LinuxThreads.
+- Calling `pthread_kill_other_threads_np' before `exec*' achieves
+- much of the same behavior, except that if `exec*' ultimately
+- fails, then all other threads are already killed.
+-
+- - Function: int pthread_once (pthread_once_t *once_CONTROL, void
+- (*INIT_ROUTINE) (void))
+- The purpose of `pthread_once' is to ensure that a piece of
+- initialization code is executed at most once. The ONCE_CONTROL
+- argument points to a static or extern variable statically
+- initialized to `PTHREAD_ONCE_INIT'.
+-
+- The first time `pthread_once' is called with a given ONCE_CONTROL
+- argument, it calls INIT_ROUTINE with no argument and changes the
+- value of the ONCE_CONTROL variable to record that initialization
+- has been performed. Subsequent calls to `pthread_once' with the
+- same `once_control' argument do nothing.
+-
+- If a thread is cancelled while executing INIT_ROUTINE the state of
+- the ONCE_CONTROL variable is reset so that a future call to
+- `pthread_once' will call the routine again.
+-
+- If the process forks while one or more threads are executing
+- `pthread_once' initialization routines, the states of their
+- respective ONCE_CONTROL variables will appear to be reset in the
+- child process so that if the child calls `pthread_once', the
+- routines will be executed.
+-
+- `pthread_once' always returns 0.
+-
+- - Function: int pthread_setschedparam (pthread_t target_THREAD, int
+- POLICY, const struct sched_param *PARAM)
+- `pthread_setschedparam' sets the scheduling parameters for the
+- thread TARGET_THREAD as indicated by POLICY and PARAM. POLICY can
+- be either `SCHED_OTHER' (regular, non-realtime scheduling),
+- `SCHED_RR' (realtime, round-robin) or `SCHED_FIFO' (realtime,
+- first-in first-out). PARAM specifies the scheduling priority for
+- the two realtime policies. See `sched_setpolicy' for more
+- information on scheduling policies.
+-
+- The realtime scheduling policies `SCHED_RR' and `SCHED_FIFO' are
+- available only to processes with superuser privileges.
+-
+- On success, `pthread_setschedparam' returns 0. On error it returns
+- one of the following codes:
+- `EINVAL'
+- POLICY is not one of `SCHED_OTHER', `SCHED_RR', `SCHED_FIFO',
+- or the priority value specified by PARAM is not valid for the
+- specified policy
+-
+- `EPERM'
+- Realtime scheduling was requested but the calling process
+- does not have sufficient privileges.
+-
+- `ESRCH'
+- The TARGET_THREAD is invalid or has already terminated
+-
+- `EFAULT'
+- PARAM points outside the process memory space
+-
+- - Function: int pthread_getschedparam (pthread_t target_THREAD, int
+- *POLICY, struct sched_param *PARAM)
+- `pthread_getschedparam' retrieves the scheduling policy and
+- scheduling parameters for the thread TARGET_THREAD and stores them
+- in the locations pointed to by POLICY and PARAM, respectively.
+-
+- `pthread_getschedparam' returns 0 on success, or one of the
+- following error codes on failure:
+- `ESRCH'
+- The TARGET_THREAD is invalid or has already terminated.
+-
+- `EFAULT'
+- POLICY or PARAM point outside the process memory space.
+-
+-
+- - Function: int pthread_setconcurrency (int LEVEL)
+- `pthread_setconcurrency' is unused in LinuxThreads due to the lack
+- of a mapping of user threads to kernel threads. It exists for
+- source compatibility. It does store the value LEVEL so that it
+- can be returned by a subsequent call to `pthread_getconcurrency'.
+- It takes no other action however.
+-
+- - Function: int pthread_getconcurrency ()
+- `pthread_getconcurrency' is unused in LinuxThreads due to the lack
+- of a mapping of user threads to kernel threads. It exists for
+- source compatibility. However, it will return the value that was
+- set by the last call to `pthread_setconcurrency'.

+-Explicitly Checking Internal Consistency
+-========================================
+-
+- When you're writing a program, it's often a good idea to put in
+-checks at strategic places for "impossible" errors or violations of
+-basic assumptions. These kinds of checks are helpful in debugging
+-problems with the interfaces between different parts of the program,
+-for example.
+-
+- The `assert' macro, defined in the header file `assert.h', provides
+-a convenient way to abort the program while printing a message about
+-where in the program the error was detected.
+-
+- Once you think your program is debugged, you can disable the error
+-checks performed by the `assert' macro by recompiling with the macro
+-`NDEBUG' defined. This means you don't actually have to change the
+-program source code to disable these checks.
+-
+- But disabling these consistency checks is undesirable unless they
+-make the program significantly slower. All else being equal, more error
+-checking is good no matter who is running the program. A wise user
+-would rather have a program crash, visibly, than have it return nonsense
+-without indicating anything might be wrong.
+-
+- - Macro: void assert (int EXPRESSION)
+- Verify the programmer's belief that EXPRESSION is nonzero at this
+- point in the program.
+-
+- If `NDEBUG' is not defined, `assert' tests the value of
+- EXPRESSION. If it is false (zero), `assert' aborts the program
+- (*note Aborting a Program::) after printing a message of the form:
+-
+- `FILE':LINENUM: FUNCTION: Assertion `EXPRESSION' failed.
+-
+- on the standard error stream `stderr' (*note Standard Streams::).
+- The filename and line number are taken from the C preprocessor
+- macros `__FILE__' and `__LINE__' and specify where the call to
+- `assert' was made. When using the GNU C compiler, the name of the
+- function which calls `assert' is taken from the built-in variable
+- `__PRETTY_FUNCTION__'; with older compilers, the function name and
+- following colon are omitted.
+-
+- If the preprocessor macro `NDEBUG' is defined before `assert.h' is
+- included, the `assert' macro is defined to do absolutely nothing.
+-
+- *Warning:* Even the argument expression EXPRESSION is not
+- evaluated if `NDEBUG' is in effect. So never use `assert' with
+- arguments that involve side effects. For example, `assert (++i >
+- 0);' is a bad idea, because `i' will not be incremented if
+- `NDEBUG' is defined.
+-
+- Sometimes the "impossible" condition you want to check for is an
+-error return from an operating system function. Then it is useful to
+-display not only where the program crashes, but also what error was
+-returned. The `assert_perror' macro makes this easy.
+-
+- - Macro: void assert_perror (int ERRNUM)
+- Similar to `assert', but verifies that ERRNUM is zero.
+-
+- If `NDEBUG' is not defined, `assert_perror' tests the value of
+- ERRNUM. If it is nonzero, `assert_perror' aborts the program
+- after printing a message of the form:
+-
+- `FILE':LINENUM: FUNCTION: ERROR TEXT
+-
+- on the standard error stream. The file name, line number, and
+- function name are as for `assert'. The error text is the result of
+- `strerror (ERRNUM)'. *Note Error Messages::.
+-
+- Like `assert', if `NDEBUG' is defined before `assert.h' is
+- included, the `assert_perror' macro does absolutely nothing. It
+- does not evaluate the argument, so ERRNUM should not have any side
+- effects. It is best for ERRNUM to be just a simple variable
+- reference; often it will be `errno'.
+-
+- This macro is a GNU extension.
+-
+- *Usage note:* The `assert' facility is designed for detecting
+-_internal inconsistency_; it is not suitable for reporting invalid
+-input or improper usage by the _user_ of the program.
+-
+- The information in the diagnostic messages printed by the `assert'
+-and `assert_perror' macro is intended to help you, the programmer,
+-track down the cause of a bug, but is not really useful for telling a
+-user of your program why his or her input was invalid or why a command
+-could not be carried out. What's more, your program should not abort
+-when given invalid input, as `assert' would do--it should exit with
+-nonzero status (*note Exit Status::) after printing its error messages,
+-or perhaps read another command or move on to the next input file.
+-
+- *Note Error Messages::, for information on printing error messages
+-for problems that _do not_ represent bugs in the program.

+-Variadic Functions
+-==================
+-
+- ISO C defines a syntax for declaring a function to take a variable
+-number or type of arguments. (Such functions are referred to as
+-"varargs functions" or "variadic functions".) However, the language

+-
+-Why Variadic Functions are Used
+--------------------------------
+-
+- Ordinary C functions take a fixed number of arguments. When you
+-define a function, you specify the data type for each argument. Every
+-call to the function should supply the expected number of arguments,
+-with types that can be converted to the specified ones. Thus, if the
+-function `foo' is declared with `int foo (int, char *);' then you must
+-call it with two arguments, a number (any kind will do) and a string
+-pointer.
+-
+- But some functions perform operations that can meaningfully accept an
+-unlimited number of arguments.
+-
+- In some cases a function can handle any number of values by
+-operating on all of them as a block. For example, consider a function
+-that allocates a one-dimensional array with `malloc' to hold a
+-specified set of values. This operation makes sense for any number of
+-values, as long as the length of the array corresponds to that number.
+-Without facilities for variable arguments, you would have to define a
+-separate function for each possible array size.
+-
+- The library function `printf' (*note Formatted Output::) is an
+-example of another class of function where variable arguments are
+-useful. This function prints its arguments (which can vary in type as
+-well as number) under the control of a format template string.
+-
+- These are good reasons to define a "variadic" function which can
+-handle as many arguments as the caller chooses to pass.
+-
+- Some functions such as `open' take a fixed set of arguments, but
+-occasionally ignore the last few. Strict adherence to ISO C requires
+-these functions to be defined as variadic; in practice, however, the GNU
+-C compiler and most other C compilers let you define such a function to
+-take a fixed set of arguments--the most it can ever use--and then only
+-_declare_ the function as variadic (or not declare its arguments at
+-all!).

+-Syntax for Variable Arguments
+-.............................
+-
+- A function that accepts a variable number of arguments must be
+-declared with a prototype that says so. You write the fixed arguments
+-as usual, and then tack on `...' to indicate the possibility of
+-additional arguments. The syntax of ISO C requires at least one fixed
+-argument before the `...'. For example,
+-
+- int
+- func (const char *a, int b, ...)
+- {
+- ...
+- }
+-
+-defines a function `func' which returns an `int' and takes two required
+-arguments, a `const char *' and an `int'. These are followed by any
+-number of anonymous arguments.
+-
+- *Portability note:* For some C compilers, the last required argument
+-must not be declared `register' in the function definition.
+-Furthermore, this argument's type must be "self-promoting": that is,
+-the default promotions must not change its type. This rules out array
+-and function types, as well as `float', `char' (whether signed or not)
+-and `short int' (whether signed or not). This is actually an ISO C
+-requirement.
+-
+-\1f
+-File: libc.info, Node: Receiving Arguments, Next: How Many Arguments, Prev: Variadic Prototypes, Up: How Variadic
+-
+-Receiving the Argument Values
+-.............................
+-
+- Ordinary fixed arguments have individual names, and you can use these
+-names to access their values. But optional arguments have no
+-names--nothing but `...'. How can you access them?
+-
+- The only way to access them is sequentially, in the order they were
+-written, and you must use special macros from `stdarg.h' in the
+-following three step process:
+-
+- 1. You initialize an argument pointer variable of type `va_list' using
+- `va_start'. The argument pointer when initialized points to the
+- first optional argument.
+-
+- 2. You access the optional arguments by successive calls to `va_arg'.
+- The first call to `va_arg' gives you the first optional argument,
+- the next call gives you the second, and so on.
+-
+- You can stop at any time if you wish to ignore any remaining
+- optional arguments. It is perfectly all right for a function to
+- access fewer arguments than were supplied in the call, but you
+- will get garbage values if you try to access too many arguments.
+-
+- 3. You indicate that you are finished with the argument pointer
+- variable by calling `va_end'.
+-
+- (In practice, with most C compilers, calling `va_end' does nothing.
+- This is always true in the GNU C compiler. But you might as well
+- call `va_end' just in case your program is someday compiled with a
+- peculiar compiler.)
+-
+- *Note Argument Macros::, for the full definitions of `va_start',
+-`va_arg' and `va_end'.
+-
+- Steps 1 and 3 must be performed in the function that accepts the
+-optional arguments. However, you can pass the `va_list' variable as an
+-argument to another function and perform all or part of step 2 there.
+-
+- You can perform the entire sequence of three steps multiple times
+-within a single function invocation. If you want to ignore the optional
+-arguments, you can do these steps zero times.
+-
+- You can have more than one argument pointer variable if you like.
+-You can initialize each variable with `va_start' when you wish, and
+-then you can fetch arguments with each argument pointer as you wish.
+-Each argument pointer variable will sequence through the same set of
+-argument values, but at its own pace.
+-
+- *Portability note:* With some compilers, once you pass an argument
+-pointer value to a subroutine, you must not keep using the same
+-argument pointer value after that subroutine returns. For full
+-portability, you should just pass it to `va_end'. This is actually an
+-ISO C requirement, but most ANSI C compilers work happily regardless.

+-
+-How Many Arguments Were Supplied
+-................................
+-
+- There is no general way for a function to determine the number and
+-type of the optional arguments it was called with. So whoever designs
+-the function typically designs a convention for the caller to specify
+-the number and type of arguments. It is up to you to define an
+-appropriate calling convention for each variadic function, and write
+-all calls accordingly.
+-
+- One kind of calling convention is to pass the number of optional
+-arguments as one of the fixed arguments. This convention works provided
+-all of the optional arguments are of the same type.
+-
+- A similar alternative is to have one of the required arguments be a
+-bit mask, with a bit for each possible purpose for which an optional
+-argument might be supplied. You would test the bits in a predefined
+-sequence; if the bit is set, fetch the value of the next argument,
+-otherwise use a default value.
+-
+- A required argument can be used as a pattern to specify both the
+-number and types of the optional arguments. The format string argument
+-to `printf' is one example of this (*note Formatted Output Functions::).
+-
+- Another possibility is to pass an "end marker" value as the last
+-optional argument. For example, for a function that manipulates an
+-arbitrary number of pointer arguments, a null pointer might indicate the
+-end of the argument list. (This assumes that a null pointer isn't
+-otherwise meaningful to the function.) The `execl' function works in
+-just this way; see *Note Executing a File::.

+-
+-Calling Variadic Functions
+-..........................
+-
+- You don't have to do anything special to call a variadic function.
+-Just put the arguments (required arguments, followed by optional ones)
+-inside parentheses, separated by commas, as usual. But you must declare
+-the function with a prototype and know how the argument values are
+-converted.
+-
+- In principle, functions that are _defined_ to be variadic must also
+-be _declared_ to be variadic using a function prototype whenever you
+-call them. (*Note Variadic Prototypes::, for how.) This is because
+-some C compilers use a different calling convention to pass the same set
+-of argument values to a function depending on whether that function
+-takes variable arguments or fixed arguments.
+-
+- In practice, the GNU C compiler always passes a given set of argument
+-types in the same way regardless of whether they are optional or
+-required. So, as long as the argument types are self-promoting, you can
+-safely omit declaring them. Usually it is a good idea to declare the
+-argument types for variadic functions, and indeed for all functions.
+-But there are a few functions which it is extremely convenient not to
+-have to declare as variadic--for example, `open' and `printf'.
+-
+- Since the prototype doesn't specify types for optional arguments, in
+-a call to a variadic function the "default argument promotions" are
+-performed on the optional argument values. This means the objects of
+-type `char' or `short int' (whether signed or not) are promoted to
+-either `int' or `unsigned int', as appropriate; and that objects of
+-type `float' are promoted to type `double'. So, if the caller passes a
+-`char' as an optional argument, it is promoted to an `int', and the
+-function can access it with `va_arg (AP, int)'.
+-
+- Conversion of the required arguments is controlled by the function
+-prototype in the usual way: the argument expression is converted to the
+-declared argument type as if it were being assigned to a variable of
+-that type.

+-
+-Argument Access Macros
+-......................
+-
+- Here are descriptions of the macros used to retrieve variable
+-arguments. These macros are defined in the header file `stdarg.h'.
+-
+- - Data Type: va_list
+- The type `va_list' is used for argument pointer variables.
+-
+- - Macro: void va_start (va_list AP, LAST-REQUIRED)
+- This macro initializes the argument pointer variable AP to point
+- to the first of the optional arguments of the current function;
+- LAST-REQUIRED must be the last required argument to the function.
+-
+- *Note Old Varargs::, for an alternate definition of `va_start'
+- found in the header file `varargs.h'.
+-
+- - Macro: TYPE va_arg (va_list AP, TYPE)
+- The `va_arg' macro returns the value of the next optional argument,
+- and modifies the value of AP to point to the subsequent argument.
+- Thus, successive uses of `va_arg' return successive optional
+- arguments.
+-
+- The type of the value returned by `va_arg' is TYPE as specified in
+- the call. TYPE must be a self-promoting type (not `char' or
+- `short int' or `float') that matches the type of the actual
+- argument.
+-
+- - Macro: void va_end (va_list AP)
+- This ends the use of AP. After a `va_end' call, further `va_arg'
+- calls with the same AP may not work. You should invoke `va_end'
+- before returning from the function in which `va_start' was invoked
+- with the same AP argument.
+-
+- In the GNU C library, `va_end' does nothing, and you need not ever
+- use it except for reasons of portability.
+-
+-
+- Sometimes it is necessary to parse the list of parameters more than
+-once or one wants to remember a certain position in the parameter list.
+-To do this, one will have to make a copy of the current value of the
+-argument. But `va_list' is an opaque type and one cannot necessarily
+-assign the value of one variable of type `va_list' to another variable
+-of the same type.
+-
+- - Macro: void __va_copy (va_list DEST, va_list SRC)
+- The `__va_copy' macro allows copying of objects of type `va_list'
+- even if this is not an integral type. The argument pointer in
+- DEST is initialized to point to the same argument as the pointer
+- in SRC.
+-
+- This macro is a GNU extension but it will hopefully also be
+- available in the next update of the ISO C standard.
+-
+- If you want to use `__va_copy' you should always be prepared for the
+-possibility that this macro will not be available. On architectures
+-where a simple assignment is invalid, hopefully `__va_copy' _will_ be
+-available, so one should always write something like this:
+-
+- {
+- va_list ap, save;
+- ...
+- #ifdef __va_copy
+- __va_copy (save, ap);
+- #else
+- save = ap;
+- #endif
+- ...

+-Old-Style Variadic Functions
+-............................
+-
+- Before ISO C, programmers used a slightly different facility for
+-writing variadic functions. The GNU C compiler still supports it;
+-currently, it is more portable than the ISO C facility, since support
+-for ISO C is still not universal. The header file which defines the
+-old-fashioned variadic facility is called `varargs.h'.
+-
+- Using `varargs.h' is almost the same as using `stdarg.h'. There is
+-no difference in how you call a variadic function; see *Note Calling
+-Variadics::. The only difference is in how you define them. First of
+-all, you must use old-style non-prototype syntax, like this:
+-
+- tree
+- build (va_alist)
+- va_dcl
+- {
+-
+- Secondly, you must give `va_start' only one argument, like this:
+-
+- va_list p;
+- va_start (p);
+-
+- These are the special macros used for defining old-style variadic
+-functions:
+-
+- - Macro: va_alist
+- This macro stands for the argument name list required in a variadic
+- function.
+-
+- - Macro: va_dcl
+- This macro declares the implicit argument or arguments for a
+- variadic function.
+-
+- - Macro: void va_start (va_list AP)
+- This macro, as defined in `varargs.h', initializes the argument
+- pointer variable AP to point to the first argument of the current
+- function.
+-
+- The other argument macros, `va_arg' and `va_end', are the same in
+-`varargs.h' as in `stdarg.h'; see *Note Argument Macros::, for details.
+-
+- It does not work to include both `varargs.h' and `stdarg.h' in the
+-same compilation; they define `va_start' in conflicting ways.

+-Null Pointer Constant
+-=====================
+-
+- The null pointer constant is guaranteed not to point to any real
+-object. You can assign it to any pointer variable since it has type
+-`void *'. The preferred way to write a null pointer constant is with
+-`NULL'.
+-
+- - Macro: void * NULL
+- This is a null pointer constant.
+-
+- You can also use `0' or `(void *)0' as a null pointer constant, but
+-using `NULL' is cleaner because it makes the purpose of the constant
+-more evident.
+-
+- If you use the null pointer constant as a function argument, then for
+-complete portability you should make sure that the function has a
+-prototype declaration. Otherwise, if the target machine has two
+-different pointer representations, the compiler won't know which
+-representation to use for that argument. You can avoid the problem by
+-explicitly casting the constant to the proper pointer type, but we
+-recommend instead adding a prototype for the function you are calling.

+-
+-Important Data Types
+-====================
+-
+- The result of subtracting two pointers in C is always an integer,
+-but the precise data type varies from C compiler to C compiler.
+-Likewise, the data type of the result of `sizeof' also varies between
+-compilers. ISO defines standard aliases for these two types, so you
+-can refer to them in a portable fashion. They are defined in the
+-header file `stddef.h'.
+-
+- - Data Type: ptrdiff_t
+- This is the signed integer type of the result of subtracting two
+- pointers. For example, with the declaration `char *p1, *p2;', the
+- expression `p2 - p1' is of type `ptrdiff_t'. This will probably
+- be one of the standard signed integer types (`short int', `int' or
+- `long int'), but might be a nonstandard type that exists only for
+- this purpose.
+-
+- - Data Type: size_t
+- This is an unsigned integer type used to represent the sizes of
+- objects. The result of the `sizeof' operator is of this type, and
+- functions such as `malloc' (*note Unconstrained Allocation::) and
+- `memcpy' (*note Copying and Concatenation::) accept arguments of
+- this type to specify object sizes.
+-
+- *Usage Note:* `size_t' is the preferred way to declare any
+- arguments or variables that hold the size of an object.
+-
+- In the GNU system `size_t' is equivalent to either `unsigned int' or
+-`unsigned long int'. These types have identical properties on the GNU
+-system and, for most purposes, you can use them interchangeably.
+-However, they are distinct as data types, which makes a difference in
+-certain contexts.
+-
+- For example, when you specify the type of a function argument in a
+-function prototype, it makes a difference which one you use. If the
+-system header files declare `malloc' with an argument of type `size_t'
+-and you declare `malloc' with an argument of type `unsigned int', you
+-will get a compilation error if `size_t' happens to be `unsigned long
+-int' on your system. To avoid any possibility of error, when a
+-function argument or value is supposed to have type `size_t', never
+-declare its type in any other way.
+-
+- *Compatibility Note:* Implementations of C before the advent of
+-ISO C generally used `unsigned int' for representing object sizes and
+-`int' for pointer subtraction results. They did not necessarily define
+-either `size_t' or `ptrdiff_t'. Unix systems did define `size_t', in
+-`sys/types.h', but the definition was usually a signed type.

+-======================
+-
+- Most of the time, if you choose the proper C data type for each
+-object in your program, you need not be concerned with just how it is
+-represented or how many bits it uses. When you do need such
+-information, the C language itself does not provide a way to get it.

+-
+-Computing the Width of an Integer Data Type
+--------------------------------------------
+-
+- The most common reason that a program needs to know how many bits
+-are in an integer type is for using an array of `long int' as a bit
+-vector. You can access the bit at index N with
+-
+- vector[N / LONGBITS] & (1 << (N % LONGBITS))
+-
+-provided you define `LONGBITS' as the number of bits in a `long int'.
+-
+- There is no operator in the C language that can give you the number
+-of bits in an integer data type. But you can compute it from the macro
+-`CHAR_BIT', defined in the header file `limits.h'.
+-
+-`CHAR_BIT'
+- This is the number of bits in a `char'--eight, on most systems.
+- The value has type `int'.
+-
+- You can compute the number of bits in any data type TYPE like this:

+-
+-Range of an Integer Type
+-------------------------
+-
+- Suppose you need to store an integer value which can range from zero
+-to one million. Which is the smallest type you can use? There is no
+-general rule; it depends on the C compiler and target machine. You can
+-use the `MIN' and `MAX' macros in `limits.h' to determine which type
+-will work.
+-
+- Each signed integer type has a pair of macros which give the smallest
+-and largest values that it can hold. Each unsigned integer type has one
+-such macro, for the maximum value; the minimum value is, of course,
+-zero.
+-
+- The values of these macros are all integer constant expressions. The
+-`MAX' and `MIN' macros for `char' and `short int' types have values of
+-type `int'. The `MAX' and `MIN' macros for the other types have values
+-of the same type described by the macro--thus, `ULONG_MAX' has type
+-`unsigned long int'.
+-
+-`SCHAR_MIN'
+- This is the minimum value that can be represented by a
+- `signed char'.
+-
+-`SCHAR_MAX'
+-`UCHAR_MAX'
+- These are the maximum values that can be represented by a
+- `signed char' and `unsigned char', respectively.
+-
+-`CHAR_MIN'
+- This is the minimum value that can be represented by a `char'.
+- It's equal to `SCHAR_MIN' if `char' is signed, or zero otherwise.
+-
+-`CHAR_MAX'
+- This is the maximum value that can be represented by a `char'.
+- It's equal to `SCHAR_MAX' if `char' is signed, or `UCHAR_MAX'
+- otherwise.
+-
+-`SHRT_MIN'
+- This is the minimum value that can be represented by a
+- `signed short int'. On most machines that the GNU C library runs
+- on, `short' integers are 16-bit quantities.
+-
+-`SHRT_MAX'
+-`USHRT_MAX'
+- These are the maximum values that can be represented by a
+- `signed short int' and `unsigned short int', respectively.
+-
+-`INT_MIN'
+- This is the minimum value that can be represented by a
+- `signed int'. On most machines that the GNU C system runs on, an
+- `int' is a 32-bit quantity.
+-
+-`INT_MAX'
+-`UINT_MAX'
+- These are the maximum values that can be represented by,
+- respectively, the type `signed int' and the type `unsigned int'.
+-
+-`LONG_MIN'
+- This is the minimum value that can be represented by a

+-Floating Point Representation Concepts
+-......................................
+-
+- This section introduces the terminology for describing floating point
+-representations.
+-
+- You are probably already familiar with most of these concepts in
+-terms of scientific or exponential notation for floating point numbers.
+-For example, the number `123456.0' could be expressed in exponential
+-notation as `1.23456e+05', a shorthand notation indicating that the
+-mantissa `1.23456' is multiplied by the base `10' raised to power `5'.
+-
+- More formally, the internal representation of a floating point number
+-can be characterized in terms of the following parameters:
+-
+- * The "sign" is either `-1' or `1'.
+-
+- * The "base" or "radix" for exponentiation, an integer greater than
+- `1'. This is a constant for a particular representation.
+-
+- * The "exponent" to which the base is raised. The upper and lower
+- bounds of the exponent value are constants for a particular
+- representation.
+-
+- Sometimes, in the actual bits representing the floating point
+- number, the exponent is "biased" by adding a constant to it, to
+- make it always be represented as an unsigned quantity. This is
+- only important if you have some reason to pick apart the bit
+- fields making up the floating point number by hand, which is
+- something for which the GNU library provides no support. So this
+- is ignored in the discussion that follows.
+-
+- * The "mantissa" or "significand" is an unsigned integer which is a
+- part of each floating point number.
+-
+- * The "precision" of the mantissa. If the base of the representation
+- is B, then the precision is the number of base-B digits in the
+- mantissa. This is a constant for a particular representation.
+-
+- Many floating point representations have an implicit "hidden bit"
+- in the mantissa. This is a bit which is present virtually in the
+- mantissa, but not stored in memory because its value is always 1
+- in a normalized number. The precision figure (see above) includes
+- any hidden bits.
+-
+- Again, the GNU library provides no facilities for dealing with such
+- low-level aspects of the representation.
+-
+- The mantissa of a floating point number represents an implicit
+-fraction whose denominator is the base raised to the power of the
+-precision. Since the largest representable mantissa is one less than
+-this denominator, the value of the fraction is always strictly less
+-than `1'. The mathematical value of a floating point number is then
+-the product of this fraction, the sign, and the base raised to the
+-exponent.
+-
+- We say that the floating point number is "normalized" if the
+-fraction is at least `1/B', where B is the base. In other words, the
+-mantissa would be too large to fit if it were multiplied by the base.
+-Non-normalized numbers are sometimes called "denormal"; they contain
+-less precision than the representation normally can hold.
+-
+- If the number is not normalized, then you can subtract `1' from the
+-exponent while multiplying the mantissa by the base, and get another
+-floating point number with the same value. "Normalization" consists of
+-doing this repeatedly until the number is normalized. Two distinct
+-normalized floating point numbers cannot be equal in value.
+-
+- (There is an exception to this rule: if the mantissa is zero, it is
+-considered normalized. Another exception happens on certain machines
+-where the exponent is as small as the representation can hold. Then it
+-is impossible to subtract `1' from the exponent, so a number may be
+-normalized even if its fraction is less than `1/B'.)

+-
+-Floating Point Parameters
+-.........................
+-
+- These macro definitions can be accessed by including the header file
+-`float.h' in your program.
+-
+- Macro names starting with `FLT_' refer to the `float' type, while
+-names beginning with `DBL_' refer to the `double' type and names
+-beginning with `LDBL_' refer to the `long double' type. (If GCC does
+-not support `long double' as a distinct data type on a target machine
+-then the values for the `LDBL_' constants are equal to the
+-corresponding constants for the `double' type.)
+-
+- Of these macros, only `FLT_RADIX' is guaranteed to be a constant
+-expression. The other macros listed here cannot be reliably used in
+-places that require constant expressions, such as `#if' preprocessing
+-directives or in the dimensions of static arrays.
+-
+- Although the ISO C standard specifies minimum and maximum values for
+-most of these parameters, the GNU C implementation uses whatever values
+-describe the floating point representation of the target machine. So in
+-principle GNU C actually satisfies the ISO C requirements only if the
+-target machine is suitable. In practice, all the machines currently
+-supported are suitable.
+-
+-`FLT_ROUNDS'
+- This value characterizes the rounding mode for floating point
+- addition. The following values indicate standard rounding modes:
+-
+- `-1'
+- The mode is indeterminable.
+-
+- `0'
+- Rounding is towards zero.
+-
+- `1'
+- Rounding is to the nearest number.
+-
+- `2'
+- Rounding is towards positive infinity.
+-
+- `3'
+- Rounding is towards negative infinity.
+-
+- Any other value represents a machine-dependent nonstandard rounding
+- mode.
+-
+- On most machines, the value is `1', in accordance with the IEEE
+- standard for floating point.
+-
+- Here is a table showing how certain values round for each possible
+- value of `FLT_ROUNDS', if the other aspects of the representation
+- match the IEEE single-precision standard.
+-
+- 0 1 2 3
+- 1.00000003 1.0 1.0 1.00000012 1.0
+- 1.00000007 1.0 1.00000012 1.00000012 1.0
+- -1.00000003 -1.0 -1.0 -1.0 -1.00000012
+- -1.00000007 -1.0 -1.00000012 -1.0 -1.00000012
+-
+-`FLT_RADIX'
+- This is the value of the base, or radix, of the exponent
+- representation. This is guaranteed to be a constant expression,
+- unlike the other macros described in this section. The value is 2
+- on all machines we know of except the IBM 360 and derivatives.
+-
+-`FLT_MANT_DIG'
+- This is the number of base-`FLT_RADIX' digits in the floating point
+- mantissa for the `float' data type. The following expression
+- yields `1.0' (even though mathematically it should not) due to the
+- limited number of mantissa digits:
+-
+- float radix = FLT_RADIX;
+-
+- 1.0f + 1.0f / radix / radix / ... / radix
+-
+- where `radix' appears `FLT_MANT_DIG' times.
+-
+-`DBL_MANT_DIG'
+-`LDBL_MANT_DIG'
+- This is the number of base-`FLT_RADIX' digits in the floating point
+- mantissa for the data types `double' and `long double',
+- respectively.
+-
+-`FLT_DIG'
+- This is the number of decimal digits of precision for the `float'
+- data type. Technically, if P and B are the precision and base
+- (respectively) for the representation, then the decimal precision
+- Q is the maximum number of decimal digits such that any floating
+- point number with Q base 10 digits can be rounded to a floating
+- point number with P base B digits and back again, without change
+- to the Q decimal digits.
+-
+- The value of this macro is supposed to be at least `6', to satisfy
+- ISO C.
+-
+-`DBL_DIG'
+-`LDBL_DIG'
+- These are similar to `FLT_DIG', but for the data types `double'
+- and `long double', respectively. The values of these macros are
+- supposed to be at least `10'.
+-
+-`FLT_MIN_EXP'
+- This is the smallest possible exponent value for type `float'.
+- More precisely, is the minimum negative integer such that the value
+- `FLT_RADIX' raised to this power minus 1 can be represented as a
+- normalized floating point number of type `float'.
+-
+-`DBL_MIN_EXP'
+-`LDBL_MIN_EXP'
+- These are similar to `FLT_MIN_EXP', but for the data types
+- `double' and `long double', respectively.
+-
+-`FLT_MIN_10_EXP'
+- This is the minimum negative integer such that `10' raised to this
+- power minus 1 can be represented as a normalized floating point
+- number of type `float'. This is supposed to be `-37' or even less.
+-
+-`DBL_MIN_10_EXP'
+-`LDBL_MIN_10_EXP'
+- These are similar to `FLT_MIN_10_EXP', but for the data types
+- `double' and `long double', respectively.
+-
+-`FLT_MAX_EXP'
+- This is the largest possible exponent value for type `float'. More
+- precisely, this is the maximum positive integer such that value
+- `FLT_RADIX' raised to this power minus 1 can be represented as a
+- floating point number of type `float'.
+-
+-`DBL_MAX_EXP'
+-`LDBL_MAX_EXP'
+- These are similar to `FLT_MAX_EXP', but for the data types
+- `double' and `long double', respectively.
+-
+-`FLT_MAX_10_EXP'
+- This is the maximum positive integer such that `10' raised to this
+- power minus 1 can be represented as a normalized floating point
+- number of type `float'. This is supposed to be at least `37'.
+-
+-`DBL_MAX_10_EXP'
+-`LDBL_MAX_10_EXP'
+- These are similar to `FLT_MAX_10_EXP', but for the data types
+- `double' and `long double', respectively.
+-
+-`FLT_MAX'
+- The value of this macro is the maximum number representable in type
+- `float'. It is supposed to be at least `1E+37'. The value has
+- type `float'.
+-
+- The smallest representable number is `- FLT_MAX'.
+-
+-`DBL_MAX'
+-`LDBL_MAX'
+- These are similar to `FLT_MAX', but for the data types `double'
+- and `long double', respectively. The type of the macro's value is
+- the same as the type it describes.
+-
+-`FLT_MIN'
+- The value of this macro is the minimum normalized positive floating
+- point number that is representable in type `float'. It is supposed
+- to be no more than `1E-37'.
+-
+-`DBL_MIN'
+-`LDBL_MIN'
+- These are similar to `FLT_MIN', but for the data types `double'
+- and `long double', respectively. The type of the macro's value is
+- the same as the type it describes.
+-
+-`FLT_EPSILON'
+- This is the minimum positive floating point number of type `float'
+- such that `1.0 + FLT_EPSILON != 1.0' is true. It's supposed to be
+- no greater than `1E-5'.
+-
+-`DBL_EPSILON'
+-`LDBL_EPSILON'
+- These are similar to `FLT_EPSILON', but for the data types
+- `double' and `long double', respectively. The type of the macro's
+- value is the same as the type it describes. The values are not
+- supposed to be greater than `1E-9'.

+-IEEE Floating Point
+-...................
+-
+- Here is an example showing how the floating type measurements come
+-out for the most common floating point representation, specified by the
+-`IEEE Standard for Binary Floating Point Arithmetic (ANSI/IEEE Std
+-754-1985)'. Nearly all computers designed since the 1980s use this
+-format.
+-
+- The IEEE single-precision float representation uses a base of 2.
+-There is a sign bit, a mantissa with 23 bits plus one hidden bit (so
+-the total precision is 24 base-2 digits), and an 8-bit exponent that
+-can represent values in the range -125 to 128, inclusive.
+-
+- So, for an implementation that uses this representation for the
+-`float' data type, appropriate values for the corresponding parameters
+-are:
+-
+- FLT_RADIX 2
+- FLT_MANT_DIG 24
+- FLT_DIG 6
+- FLT_MIN_EXP -125
+- FLT_MIN_10_EXP -37
+- FLT_MAX_EXP 128
+- FLT_MAX_10_EXP +38
+- FLT_MIN 1.17549435E-38F
+- FLT_MAX 3.40282347E+38F
+- FLT_EPSILON 1.19209290E-07F
+-
+- Here are the values for the `double' data type:
+-
+- DBL_MANT_DIG 53
+- DBL_DIG 15
+- DBL_MIN_EXP -1021
+- DBL_MIN_10_EXP -307
+- DBL_MAX_EXP 1024
+- DBL_MAX_10_EXP 308
+- DBL_MAX 1.7976931348623157E+308
+- DBL_MIN 2.2250738585072014E-308

+-Structure Field Offset Measurement
+-----------------------------------
+-
+- You can use `offsetof' to measure the location within a structure
+-type of a particular structure member.
+-
+- - Macro: size_t offsetof (TYPE, MEMBER)
+- This expands to a integer constant expression that is the offset
+- of the structure member named MEMBER in a the structure type TYPE.
+- For example, `offsetof (struct s, elem)' is the offset, in bytes,
+- of the member `elem' in a `struct s'.
+-
+- This macro won't work if MEMBER is a bit field; you get an error
+- from the C compiler in that case.

+-
+- Before you do anything else, you should read the file `FAQ' located
+-at the top level of the source tree. This file answers common questions
+-and describes problems you may experience with compilation and

+-
+- Features can be added to GNU Libc via "add-on" bundles. These are
+-separate tar files, which you unpack into the top level of the source
+-tree. Then you give `configure' the `--enable-add-ons' option to
+-activate them, and they will be compiled into the library. As of the
+-2.2 release, one important component of glibc is distributed as
+-"official" add-ons: the linuxthreads add-on. Unless you are doing an
+-unusual installation, you should get this.
+-
+- Support for POSIX threads is maintained by someone else, so it's in a

+-
+-Configuring and compiling GNU Libc
+-==================================
+-
+- GNU libc can be compiled in the source directory, but we strongly
+-advise building it in a separate build directory. For example, if you
+-have unpacked the glibc sources in `/src/gnu/glibc-2.3', create a
+-directory `/src/gnu/glibc-build' to put the object files in. This
+-allows removing the whole build directory in case an error occurs,
+-which is the safest way to get a fresh start and should always be done.
+-
+- From your object directory, run the shell script `configure' located
+-at the top level of the source tree. In the scenario above, you'd type
+-
+- $ ../glibc-2.3/configure ARGS...
+-
+- Please note that even if you're building in a separate build
+-directory, the compilation needs to modify a few files in the source
+-directory, especially some files in the manual subdirectory.
+-
+-`configure' takes many options, but you can get away with knowing only
+-two: `--prefix' and `--enable-add-ons'. The `--prefix' option tells
+-`configure' where you want glibc installed. This defaults to
+-`/usr/local'. The `--enable-add-ons' option tells `configure' to use
+-all the add-on bundles it finds in the source directory. Since
+-important functionality is provided in add-ons, you should always
+-specify this option.
+-
+- It may also be useful to set the CC and CFLAGS variables in the
+-environment when running `configure'. CC selects the C compiler that
+-will be used, and CFLAGS sets optimization options for the compiler.
+-
+- The following list describes all of the available options for
+-`configure':
+-
+-`--prefix=DIRECTORY'
+- Install machine-independent data files in subdirectories of
+- `DIRECTORY'. The default is to install in `/usr/local'.
+-
+-`--exec-prefix=DIRECTORY'
+- Install the library and other machine-dependent files in
+- subdirectories of `DIRECTORY'. The default is to the `--prefix'
+- directory if that option is specified, or `/usr/local' otherwise.
+-
+-`--with-headers=DIRECTORY'
+- Look for kernel header files in DIRECTORY, not `/usr/include'.
+- Glibc needs information from the kernel's private header files.
+- Glibc will normally look in `/usr/include' for them, but if you
+- specify this option, it will look in DIRECTORY instead.
+-
+- This option is primarily of use on a system where the headers in
+- `/usr/include' come from an older version of glibc. Conflicts can
+- occasionally happen in this case. Note that Linux libc5 qualifies
+- as an older version of glibc. You can also use this option if you
+- want to compile glibc with a newer set of kernel headers than the
+- ones found in `/usr/include'.
+-
+-`--enable-add-ons[=LIST]'
+- Enable add-on packages in your source tree. If this option is
+- specified with no list, it enables all the add-on packages it
+- finds. If you do not wish to use some add-on packages that you
+- have present in your source tree, give this option a list of the
+- add-ons that you _do_ want used, like this:
+- `--enable-add-ons=linuxthreads'
+-
+-`--enable-kernel=VERSION'
+- This option is currently only useful on GNU/Linux systems. The
+- VERSION parameter should have the form X.Y.Z and describes the
+- smallest version of the Linux kernel the generated library is
+- expected to support. The higher the VERSION number is, the less
+- compatibility code is added, and the faster the code gets.
+-
+-`--with-binutils=DIRECTORY'
+- Use the binutils (assembler and linker) in `DIRECTORY', not the
+- ones the C compiler would default to. You can use this option if
+- the default binutils on your system cannot deal with all the
+- constructs in the GNU C library. In that case, `configure' will
+- detect the problem and suppress these constructs, so that the
+- library will still be usable, but functionality may be lost--for
+- example, you can't build a shared libc with old binutils.
+-
+-`--without-fp'
+- Use this option if your computer lacks hardware floating-point
+- support and your operating system does not emulate an FPU.
+-
+- these
+-
+-`--disable-shared'
+- Don't build shared libraries even if it is possible. Not all
+- systems support shared libraries; you need ELF support and
+- (currently) the GNU linker.
+-
+-`--disable-profile'
+- Don't build libraries with profiling information. You may want to
+- use this option if you don't plan to do profiling.
+-
+-`--enable-omitfp'
+- Use maximum optimization for the normal (static and shared)
+- libraries, and compile separate static libraries with debugging
+- information and no optimization. We recommend not doing this.
+- The extra optimization doesn't gain you much, it may provoke
+- compiler bugs, and you won't be able to trace bugs through the C
+- library.
+-
+-`--disable-versioning'
+- Don't compile the shared libraries with symbol version information.
+- Doing this will make the resulting library incompatible with old
+- binaries, so it's not recommended.
+-
+-`--enable-static-nss'
+- Compile static versions of the NSS (Name Service Switch) libraries.
+- This is not recommended because it defeats the purpose of NSS; a
+- program linked statically with the NSS libraries cannot be
+- dynamically reconfigured to use a different name database.
+-
+-`--without-tls'
+- By default the C library is built with support for thread-local
+- storage if the used tools support it. By using `--without-tls'
+- this can be prevented though there generally is no reason since it
+- creates compatibility problems.
+-
+-`--build=BUILD-SYSTEM'
+-`--host=HOST-SYSTEM'
+- These options are for cross-compiling. If you specify both
+- options and BUILD-SYSTEM is different from HOST-SYSTEM, `configure'
+- will prepare to cross-compile glibc from BUILD-SYSTEM to be used
+- on HOST-SYSTEM. You'll probably need the `--with-headers' option
+- too, and you may have to override CONFIGURE's selection of the
+- compiler and/or binutils.
+-
+- If you only specify `--host', `configure' will prepare for a
+- native compile but use what you specify instead of guessing what
+- your system is. This is most useful to change the CPU submodel.
+- For example, if `configure' guesses your machine as
+- `i586-pc-linux-gnu' but you want to compile a library for 386es,
+- give `--host=i386-pc-linux-gnu' or just `--host=i386-linux' and add
+- the appropriate compiler flags (`-mcpu=i386' will do the trick) to
+- CFLAGS.
+-
+- If you specify just `--build', `configure' will get confused.
+-
+- To build the library and related programs, type `make'. This will
+-produce a lot of output, some of which may look like errors from `make'
+-but isn't. Look for error messages from `make' containing `***'.
+-Those indicate that something is seriously wrong.
+-
+- The compilation process can take several hours. Expect at least two
+-hours for the default configuration on i586 for GNU/Linux. For Hurd,
+-times are much longer. Some complex modules may take a very long time
+-to compile, as much as several minutes on slower machines. Do not
+-panic if the compiler appears to hang.
+-
+- If you want to run a parallel make, simply pass the `-j' option with
+-an appropriate numeric parameter to `make'. You need a recent GNU
+-`make' version, though.
+-
+- To build and run test programs which exercise some of the library
+-facilities, type `make check'. If it does not complete successfully,
+-do not use the built library, and report a bug after verifying that the
+-problem is not already known. *Note Reporting Bugs::, for instructions
+-on reporting bugs. Note that some of the tests assume they are not
+-being run by `root'. We recommend you compile and test glibc as an
+-unprivileged user.
+-
+- Before reporting bugs make sure there is no problem with your system.
+-The tests (and later installation) use some pre-existing files of the
+-system such as `/etc/passwd', `/etc/nsswitch.conf' and others. These
+-files must all contain correct and sensible content.
+-
+- To format the `GNU C Library Reference Manual' for printing, type
+-`make dvi'. You need a working TeX installation to do this. The
+-distribution already includes the on-line formatted version of the
+-manual, as Info files. You can regenerate those with `make info', but
+-it shouldn't be necessary.
+-
+- The library has a number of special-purpose configuration parameters
+-which you can find in `Makeconfig'. These can be overwritten with the
+-file `configparms'. To change them, create a `configparms' in your
+-build directory and add values as appropriate for your system. The
+-file is included and parsed by `make' and has to follow the conventions
+-for makefiles.
+-
+- It is easy to configure the GNU C library for cross-compilation by
+-setting a few variables in `configparms'. Set `CC' to the
+-cross-compiler for the target you configured the library for; it is
+-important to use this same `CC' value when running `configure', like
+-this: `CC=TARGET-gcc configure TARGET'. Set `BUILD_CC' to the compiler
+-to use for programs run on the build system as part of compiling the
+-library. You may need to set `AR' and `RANLIB' to cross-compiling
+-versions of `ar' and `ranlib' if the native tools are not configured to
+-work with object files for the target you configured for.

+-
+-Installing the C Library
+-========================
+-
+- To install the library and its header files, and the Info files of
+-the manual, type `env LANGUAGE=C LC_ALL=C make install'. This will
+-build things, if necessary, before installing them; however, you should
+-still compile everything first. If you are installing glibc as your
+-primary C library, we recommend that you shut the system down to
+-single-user mode first, and reboot afterward. This minimizes the risk
+-of breaking things when the library changes out from underneath.
+-
+- If you're upgrading from Linux libc5 or some other C library, you
+-need to replace the `/usr/include' with a fresh directory before
+-installing it. The new `/usr/include' should contain the Linux
+-headers, but nothing else.
+-
+- You must first build the library (`make'), optionally check it
+-(`make check'), switch the include directories and then install (`make
+-install'). The steps must be done in this order. Not moving the
+-directory before install will result in an unusable mixture of header
+-files from both libraries, but configuring, building, and checking the
+-library requires the ability to compile and run programs against the old
+-library.
+-
+- If you are upgrading from a previous installation of glibc 2.0 or
+-2.1, `make install' will do the entire job. You do not need to remove
+-the old includes - if you want to do so anyway you must then follow the
+-order given above.
+-
+- You may also need to reconfigure GCC to work with the new library.
+-The easiest way to do that is to figure out the compiler switches to
+-make it work again (`-Wl,--dynamic-linker=/lib/ld-linux.so.2' should
+-work on GNU/Linux systems) and use them to recompile gcc. You can also
+-edit the specs file (`/usr/lib/gcc-lib/TARGET/VERSION/specs'), but that
+-is a bit of a black art.
+-
+- You can install glibc somewhere other than where you configured it
+-to go by setting the `install_root' variable on the command line for
+-`make install'. The value of this variable is prepended to all the
+-paths for installation. This is useful when setting up a chroot
+-environment or preparing a binary distribution. The directory should be
+-specified with an absolute file name.
+-
+- Glibc 2.2 includes a daemon called `nscd', which you may or may not
+-want to run. `nscd' caches name service lookups; it can dramatically
+-improve performance with NIS+, and may help with DNS as well.
+-
+- One auxiliary program, `/usr/libexec/pt_chown', is installed setuid
+-`root'. This program is invoked by the `grantpt' function; it sets the
+-permissions on a pseudoterminal so it can be used by the calling
+-process. This means programs like `xterm' and `screen' do not have to
+-be setuid to get a pty. (There may be other reasons why they need
+-privileges.) If you are using a 2.1 or newer Linux kernel with the
+-`devptsfs' or `devfs' filesystems providing pty slaves, you don't need
+-this program; otherwise you do. The source for `pt_chown' is in
+-`login/programs/pt_chown.c'.
+-
+- After installation you might want to configure the timezone and
+-locale installation of your system. The GNU C library comes with a
+-locale database which gets configured with `localedef'. For example, to
+-set up a German locale with name `de_DE', simply issue the command
+-`localedef -i de_DE -f ISO-8859-1 de_DE'. To configure all locales
+-that are supported by glibc, you can issue from your build directory the
+-command `make localedata/install-locales'.
+-
+- To configure the locally used timezone, set the `TZ' environment
+-variable. The script `tzselect' helps you to select the right value.
+-As an example, for Germany, `tzselect' would tell you to use
+-`TZ='Europe/Berlin''. For a system wide installation (the given paths
+-are for an installation with `--prefix=/usr'), link the timezone file
+-which is in `/usr/share/zoneinfo' to the file `/etc/localtime'. For
+-Germany, you might execute `ln -s /usr/share/zoneinfo/Europe/Berlin
+-/etc/localtime'.

+-
+-Recommended Tools for Compilation
+-=================================
+-
+- We recommend installing the following GNU tools before attempting to
+-build the GNU C library:
+-
+- * GNU `make' 3.79 or newer
+-
+- You need the latest version of GNU `make'. Modifying the GNU C
+- Library to work with other `make' programs would be so difficult
+- that we recommend you port GNU `make' instead. *Really.* We
+- recommend GNU `make' version 3.79. All earlier versions have
+- severe bugs or lack features.
+-
+- * GCC 3.2 or newer
+-
+- The GNU C library can only be compiled with the GNU C compiler
+- family. As of the 2.3 release, GCC 3.2 or higher is required. As
+- of this writing, GCC 3.2 is the compiler we advise to use.
+-
+- You can use whatever compiler you like to compile programs that
+- use GNU libc, but be aware that both GCC 2.7 and 2.8 have bugs in
+- their floating-point support that may be triggered by the math
+- library.
+-
+- Check the FAQ for any special compiler issues on particular
+- platforms.
+-
+- * GNU `binutils' 2.13 or later
+-
+- You must use GNU `binutils' (as and ld) to build the GNU C library.
+- No other assembler and linker has the necessary functionality in
+- the moment.
+-
+- * GNU `texinfo' 3.12f
+-
+- To correctly translate and install the Texinfo documentation you
+- need this version of the `texinfo' package. Earlier versions do
+- not understand all the tags used in the document, and the
+- installation mechanism for the info files is not present or works
+- differently.
+-
+- * GNU `awk' 3.0, or some other POSIX awk
+-
+- `Awk' is used in several places to generate files. The scripts
+- should work with any POSIX-compliant `awk' implementation; `gawk'
+- 3.0 and `mawk' 1.3 are known to work.
+-
+- * Perl 5
+-
+- Perl is not required, but it is used if present to test the
+- installation. We may decide to use it elsewhere in the future.
+-
+- * GNU `sed' 3.02 or newer
+-
+- `Sed' is used in several places to generate files. Most scripts
+- work with any version of `sed'. The known exception is the script
+- `po2test.sed' in the `intl' subdirectory which is used to generate
+- `msgs.h' for the test suite. This script works correctly only
+- with GNU `sed' 3.02. If you like to run the test suite, you
+- should definitely upgrade `sed'.
+-
+-
+-If you change any of the `configure.in' files you will also need
+-
+- * GNU `autoconf' 2.12 or higher
+-
+-and if you change any of the message translation files you will need
+-
+- * GNU `gettext' 0.10.36 or later
+-
+-You may also need these packages if you upgrade your source tree using
+-patches, although we try to avoid this.

+- Since no one has volunteered to test and fix these configurations,

+-If you are interested in doing a port, please contact the glibc
+-maintainers by sending electronic mail to <bug-glibc@gnu.org>.
+-
+- Valid cases of `iX86' include `i386', `i486', `i586', and `i686'.
+-All of those configurations produce a library that can run on this
+-processor and newer processors. The GCC compiler by default generates
+-code that's optimized for the machine it's configured for and will use
+-the instructions available on that machine. For example if your GCC is
+-configured for `i686', gcc will optimize for `i686' and might issue
+-some `i686' specific instructions. To generate code for other models,
+-you have to configure for that model and give GCC the appropriate
+-`-march=' and `-mcpu=' compiler switches via CFLAGS.

+-
+-Specific advice for GNU/Linux systems
+-=====================================
+-
+- If you are installing GNU libc on a GNU/Linux system, you need to
+-have the header files from a 2.2 or newer kernel around for reference.
+-For some architectures, like ia64, sh and hppa, you need at least
+-headers from kernel 2.3.99 (sh and hppa) or 2.4.0 (ia64). You do not
+-need to use that kernel, just have its headers where glibc can access
+-at them. The easiest way to do this is to unpack it in a directory
+-such as `/usr/src/linux-2.2.1'. In that directory, run `make config'
+-and accept all the defaults. Then run `make include/linux/version.h'.
+-Finally, configure glibc with the option
+-`--with-headers=/usr/src/linux-2.2.1/include'. Use the most recent
+-kernel you can get your hands on.
+-
+- An alternate tactic is to unpack the 2.2 kernel and run `make
+-config' as above; then, rename or delete `/usr/include', create a new
+-`/usr/include', and make symbolic links of `/usr/include/linux' and
+-`/usr/include/asm' into the kernel sources. You can then configure
+-glibc with no special options. This tactic is recommended if you are
+-upgrading from libc5, since you need to get rid of the old header files
+-anyway.
+-
+- After installing GNU libc, you may need to remove or rename
+-`/usr/include/linux' and `/usr/include/asm', and replace them with
+-copies of `include/linux' and `include/asm-$ARCHITECTURE' taken from
+-the Linux source package which supplied kernel headers for building the
+-library. ARCHITECTURE will be the machine architecture for which the
+-library was built, such as `i386' or `alpha'. You do not need to do
+-this if you did not specify an alternate kernel header source using
+-`--with-headers'. The intent here is that these directories should be
+-copies of, *not* symlinks to, the kernel headers used to build the
+-library.
+-
+- Note that `/usr/include/net' and `/usr/include/scsi' should *not* be
+-symlinks into the kernel sources. GNU libc provides its own versions
+-of these files.
+-
+- GNU/Linux expects some components of the libc installation to be in
+-`/lib' and some in `/usr/lib'. This is handled automatically if you
+-configure glibc with `--prefix=/usr'. If you set some other prefix or
+-allow it to default to `/usr/local', then all the components are
+-installed there.
+-
+- If you are upgrading from libc5, you need to recompile every shared
+-library on your system against the new library for the sake of new code,
+-but keep the old libraries around for old binaries to use. This is
+-complicated and difficult. Consult the Glibc2 HOWTO at
+-<http://www.imaxx.net/~thrytis/glibc> for details.
+-
+- You cannot use `nscd' with 2.0 kernels, due to bugs in the
+-kernel-side thread support. `nscd' happens to hit these bugs
+-particularly hard, but you might have problems with any threaded
+-program.

+-
+-Reporting Bugs
+-==============
+-
+- There are probably bugs in the GNU C library. There are certainly
+-errors and omissions in this manual. If you report them, they will get
+-fixed. If you don't, no one will ever know about them and they will
+-remain unfixed for all eternity, if not longer.
+-
+- It is a good idea to verify that the problem has not already been
+-reported. Bugs are documented in two places: The file `BUGS' describes
+-a number of well known bugs and the bug tracking system has a WWW
+-interface at <http://www-gnats.gnu.org:8080/cgi-bin/wwwgnats.pl>. The
+-WWW interface gives you access to open and closed reports. A closed
+-report normally includes a patch or a hint on solving the problem.
+-
+- To report a bug, first you must find it. With any luck, this will
+-be the hard part. Once you've found a bug, make sure it's really a
+-bug. A good way to do this is to see if the GNU C library behaves the
+-same way some other C library does. If so, probably you are wrong and
+-the libraries are right (but not necessarily). If not, one of the
+-libraries is probably wrong. It might not be the GNU library. Many
+-historical Unix C libraries permit things that we don't, such as
+-closing a file twice.
+-
+- If you think you have found some way in which the GNU C library does
+-not conform to the ISO and POSIX standards (*note Standards and
+-Portability::), that is definitely a bug. Report it!
+-
+- Once you're sure you've found a bug, try to narrow it down to the
+-smallest test case that reproduces the problem. In the case of a C
+-library, you really only need to narrow it down to one library function
+-call, if possible. This should not be too difficult.
+-
+- The final step when you have a simple test case is to report the bug.
+-Do this using the `glibcbug' script. It is installed with libc, or if
+-you haven't installed it, will be in your build directory. Send your
+-test case, the results you got, the results you expected, and what you
+-think the problem might be (if you've thought of anything). `glibcbug'
+-will insert the configuration information we need to see, and ship the
+-report off to <bugs@gnu.org>. Don't send a message there directly; it
+-is fed to a program that expects mail to be formatted in a particular
+-way. Use the script.
+-
+- If you are not sure how a function should behave, and this manual
+-doesn't tell you, that's a bug in the manual. Report that too! If the
+-function's behavior disagrees with the manual, then either the library
+-or the manual has a bug, so report the disagreement. If you find any
+-errors or omissions in this manual, please report them to the Internet
+-address <bug-glibc-manual@gnu.org>. If you refer to specific sections
+-of the manual, please include the section names for easier
+-identification.

+-Adding New Functions
+-====================
+-
+- The process of building the library is driven by the makefiles, which
+-make heavy use of special features of GNU `make'. The makefiles are
+-very complex, and you probably don't want to try to understand them.
+-But what they do is fairly straightforward, and only requires that you
+-define a few variables in the right places.
+-
+- The library sources are divided into subdirectories, grouped by
+-topic.
+-
+- The `string' subdirectory has all the string-manipulation functions,
+-`math' has all the mathematical functions, etc.
+-
+- Each subdirectory contains a simple makefile, called `Makefile',
+-which defines a few `make' variables and then includes the global
+-makefile `Rules' with a line like:
+-
+- include ../Rules
+-
+-The basic variables that a subdirectory makefile defines are:
+-
+-`subdir'
+- The name of the subdirectory, for example `stdio'. This variable
+- *must* be defined.
+-
+-`headers'
+- The names of the header files in this section of the library, such
+- as `stdio.h'.
+-
+-`routines'
+-`aux'
+- The names of the modules (source files) in this section of the
+- library. These should be simple names, such as `strlen' (rather
+- than complete file names, such as `strlen.c'). Use `routines' for
+- modules that define functions in the library, and `aux' for
+- auxiliary modules containing things like data definitions. But the
+- values of `routines' and `aux' are just concatenated, so there
+- really is no practical difference.
+-
+-`tests'
+- The names of test programs for this section of the library. These
+- should be simple names, such as `tester' (rather than complete file
+- names, such as `tester.c'). `make tests' will build and run all
+- the test programs. If a test program needs input, put the test
+- data in a file called `TEST-PROGRAM.input'; it will be given to
+- the test program on its standard input. If a test program wants
+- to be run with arguments, put the arguments (all on a single line)
+- in a file called `TEST-PROGRAM.args'. Test programs should exit
+- with zero status when the test passes, and nonzero status when the
+- test indicates a bug in the library or error in building.
+-
+-`others'
+- The names of "other" programs associated with this section of the
+- library. These are programs which are not tests per se, but are
+- other small programs included with the library. They are built by
+- `make others'.
+-
+-`install-lib'
+-`install-data'
+-`install'
+- Files to be installed by `make install'. Files listed in
+- `install-lib' are installed in the directory specified by `libdir'
+- in `configparms' or `Makeconfig' (*note Installation::). Files
+- listed in `install-data' are installed in the directory specified
+- by `datadir' in `configparms' or `Makeconfig'. Files listed in
+- `install' are installed in the directory specified by `bindir' in
+- `configparms' or `Makeconfig'.
+-
+-`distribute'
+- Other files from this subdirectory which should be put into a
+- distribution tar file. You need not list here the makefile itself
+- or the source and header files listed in the other standard
+- variables. Only define `distribute' if there are files used in an
+- unusual way that should go into the distribution.
+-
+-`generated'
+- Files which are generated by `Makefile' in this subdirectory.
+- These files will be removed by `make clean', and they will never
+- go into a distribution.
+-
+-`extra-objs'
+- Extra object files which are built by `Makefile' in this
+- subdirectory. This should be a list of file names like `foo.o';
+- the files will actually be found in whatever directory object
+- files are being built in. These files will be removed by
+- `make clean'. This variable is used for secondary object files
+- needed to build `others' or `tests'.

+-
+-Porting the GNU C Library
+-=========================
+-
+- The GNU C library is written to be easily portable to a variety of
+-machines and operating systems. Machine- and operating system-dependent
+-functions are well separated to make it easy to add implementations for
+-new machines or operating systems. This section describes the layout of
+-the library source tree and explains the mechanisms used to select
+-machine-dependent code to use.
+-
+- All the machine-dependent and operating system-dependent files in the
+-library are in the subdirectory `sysdeps' under the top-level library
+-source directory. This directory contains a hierarchy of
+-subdirectories (*note Hierarchy Conventions::).
+-
+- Each subdirectory of `sysdeps' contains source files for a
+-particular machine or operating system, or for a class of machine or
+-operating system (for example, systems by a particular vendor, or all
+-machines that use IEEE 754 floating-point format). A configuration
+-specifies an ordered list of these subdirectories. Each subdirectory
+-implicitly appends its parent directory to the list. For example,
+-specifying the list `unix/bsd/vax' is equivalent to specifying the list
+-`unix/bsd/vax unix/bsd unix'. A subdirectory can also specify that it
+-implies other subdirectories which are not directly above it in the
+-directory hierarchy. If the file `Implies' exists in a subdirectory,
+-it lists other subdirectories of `sysdeps' which are appended to the
+-list, appearing after the subdirectory containing the `Implies' file.
+-Lines in an `Implies' file that begin with a `#' character are ignored
+-as comments. For example, `unix/bsd/Implies' contains:
+- # BSD has Internet-related things.
+- unix/inet
+-
+-and `unix/Implies' contains:
+- posix
+-
+-So the final list is `unix/bsd/vax unix/bsd unix/inet unix posix'.
+-
+- `sysdeps' has a "special" subdirectory called `generic'. It is
+-always implicitly appended to the list of subdirectories, so you
+-needn't put it in an `Implies' file, and you should not create any
+-subdirectories under it intended to be new specific categories.
+-`generic' serves two purposes. First, the makefiles do not bother to
+-look for a system-dependent version of a file that's not in `generic'.
+-This means that any system-dependent source file must have an analogue
+-in `generic', even if the routines defined by that file are not
+-implemented on other platforms. Second. the `generic' version of a
+-system-dependent file is used if the makefiles do not find a version
+-specific to the system you're compiling for.
+-
+- If it is possible to implement the routines in a `generic' file in
+-machine-independent C, using only other machine-independent functions in
+-the C library, then you should do so. Otherwise, make them stubs. A
+-"stub" function is a function which cannot be implemented on a
+-particular machine or operating system. Stub functions always return an
+-error, and set `errno' to `ENOSYS' (Function not implemented). *Note
+-Error Reporting::. If you define a stub function, you must place the
+-statement `stub_warning(FUNCTION)', where FUNCTION is the name of your
+-function, after its definition; also, you must include the file
+-`<stub-tag.h>' into your file. This causes the function to be listed
+-in the installed `<gnu/stubs.h>', and makes GNU ld warn when the
+-function is used.
+-
+- Some rare functions are only useful on specific systems and aren't
+-defined at all on others; these do not appear anywhere in the
+-system-independent source code or makefiles (including the `generic'
+-directory), only in the system-dependent `Makefile' in the specific
+-system's subdirectory.
+-
+- If you come across a file that is in one of the main source
+-directories (`string', `stdio', etc.), and you want to write a machine-
+-or operating system-dependent version of it, move the file into
+-`sysdeps/generic' and write your new implementation in the appropriate
+-system-specific subdirectory. Note that if a file is to be
+-system-dependent, it *must not* appear in one of the main source
+-directories.
+-
+- There are a few special files that may exist in each subdirectory of
+-`sysdeps':
+-
+-`Makefile'
+- A makefile for this machine or operating system, or class of
+- machine or operating system. This file is included by the library
+- makefile `Makerules', which is used by the top-level makefile and
+- the subdirectory makefiles. It can change the variables set in the
+- including makefile or add new rules. It can use GNU `make'
+- conditional directives based on the variable `subdir' (see above)
+- to select different sets of variables and rules for different
+- sections of the library. It can also set the `make' variable
+- `sysdep-routines', to specify extra modules to be included in the
+- library. You should use `sysdep-routines' rather than adding
+- modules to `routines' because the latter is used in determining
+- what to distribute for each subdirectory of the main source tree.
+-
+- Each makefile in a subdirectory in the ordered list of
+- subdirectories to be searched is included in order. Since several
+- system-dependent makefiles may be included, each should append to
+- `sysdep-routines' rather than simply setting it:
+-
+- sysdep-routines := $(sysdep-routines) foo bar
+-
+-`Subdirs'
+- This file contains the names of new whole subdirectories under the
+- top-level library source tree that should be included for this
+- system. These subdirectories are treated just like the
+- system-independent subdirectories in the library source tree, such
+- as `stdio' and `math'.
+-
+- Use this when there are completely new sets of functions and header
+- files that should go into the library for the system this
+- subdirectory of `sysdeps' implements. For example,
+- `sysdeps/unix/inet/Subdirs' contains `inet'; the `inet' directory
+- contains various network-oriented operations which only make sense
+- to put in the library on systems that support the Internet.
+-
+-`Dist'
+- This file contains the names of files (relative to the
+- subdirectory of `sysdeps' in which it appears) which should be
+- included in the distribution. List any new files used by rules in
+- the `Makefile' in the same directory, or header files used by the
+- source files in that directory. You don't need to list files that
+- are implementations (either C or assembly source) of routines
+- whose names are given in the machine-independent makefiles in the
+- main source tree.
+-
+-`configure'
+- This file is a shell script fragment to be run at configuration
+- time. The top-level `configure' script uses the shell `.' command
+- to read the `configure' file in each system-dependent directory
+- chosen, in order. The `configure' files are often generated from
+- `configure.in' files using Autoconf.
+-
+- A system-dependent `configure' script will usually add things to
+- the shell variables `DEFS' and `config_vars'; see the top-level
+- `configure' script for details. The script can check for
+- `--with-PACKAGE' options that were passed to the top-level
+- `configure'. For an option `--with-PACKAGE=VALUE' `configure'
+- sets the shell variable `with_PACKAGE' (with any dashes in PACKAGE
+- converted to underscores) to VALUE; if the option is just
+- `--with-PACKAGE' (no argument), then it sets `with_PACKAGE' to
+- `yes'.
+-
+-`configure.in'
+- This file is an Autoconf input fragment to be processed into the
+- file `configure' in this subdirectory. *Note Introduction:
+- (autoconf.info)Introduction, for a description of Autoconf. You
+- should write either `configure' or `configure.in', but not both.
+- The first line of `configure.in' should invoke the `m4' macro
+- `GLIBC_PROVIDES'. This macro does several `AC_PROVIDE' calls for
+- Autoconf macros which are used by the top-level `configure'
+- script; without this, those macros might be invoked again
+- unnecessarily by Autoconf.
+-
+- That is the general system for how system-dependencies are isolated.

+-
+-Layout of the `sysdeps' Directory Hierarchy
+--------------------------------------------
+-
+- A GNU configuration name has three parts: the CPU type, the
+-manufacturer's name, and the operating system. `configure' uses these
+-to pick the list of system-dependent directories to look for. If the
+-`--nfp' option is _not_ passed to `configure', the directory
+-`MACHINE/fpu' is also used. The operating system often has a "base
+-operating system"; for example, if the operating system is `Linux', the
+-base operating system is `unix/sysv'. The algorithm used to pick the
+-list of directories is simple: `configure' makes a list of the base
+-operating system, manufacturer, CPU type, and operating system, in that
+-order. It then concatenates all these together with slashes in
+-between, to produce a directory name; for example, the configuration
+-`i686-linux-gnu' results in `unix/sysv/linux/i386/i686'. `configure'
+-then tries removing each element of the list in turn, so
+-`unix/sysv/linux' and `unix/sysv' are also tried, among others. Since
+-the precise version number of the operating system is often not
+-important, and it would be very inconvenient, for example, to have
+-identical `irix6.2' and `irix6.3' directories, `configure' tries
+-successively less specific operating system names by removing trailing
+-suffixes starting with a period.
+-
+- As an example, here is the complete list of directories that would be
+-tried for the configuration `i686-linux-gnu' (with the `crypt' and
+-`linuxthreads' add-on):
+-
+- sysdeps/i386/elf
+- crypt/sysdeps/unix
+- linuxthreads/sysdeps/unix/sysv/linux
+- linuxthreads/sysdeps/pthread
+- linuxthreads/sysdeps/unix/sysv
+- linuxthreads/sysdeps/unix

+- sysdeps/libm-i387
+- sysdeps/i386
+- sysdeps/wordsize-32
+- sysdeps/ieee754
+- sysdeps/libm-ieee754
+- sysdeps/generic
+-
+- Different machine architectures are conventionally subdirectories at
+-the top level of the `sysdeps' directory tree. For example,
+-`sysdeps/sparc' and `sysdeps/m68k'. These contain files specific to
+-those machine architectures, but not specific to any particular
+-operating system. There might be subdirectories for specializations of
+-those architectures, such as `sysdeps/m68k/68020'. Code which is
+-specific to the floating-point coprocessor used with a particular
+-machine should go in `sysdeps/MACHINE/fpu'.
+-
+- There are a few directories at the top level of the `sysdeps'
+-hierarchy that are not for particular machine architectures.
+-
+-`generic'
+- As described above (*note Porting::), this is the subdirectory
+- that every configuration implicitly uses after all others.
+-
+-`ieee754'
+- This directory is for code using the IEEE 754 floating-point
+- format, where the C type `float' is IEEE 754 single-precision
+- format, and `double' is IEEE 754 double-precision format. Usually
+- this directory is referred to in the `Implies' file in a machine
+- architecture-specific directory, such as `m68k/Implies'.
+-
+-`libm-ieee754'
+- This directory contains an implementation of a mathematical library
+- usable on platforms which use IEEE 754 conformant floating-point
+- arithmetic.
+-
+-`libm-i387'
+- This is a special case. Ideally the code should be in
+- `sysdeps/i386/fpu' but for various reasons it is kept aside.
+-
+-`posix'
+- This directory contains implementations of things in the library in
+- terms of POSIX.1 functions. This includes some of the POSIX.1
+- functions themselves. Of course, POSIX.1 cannot be completely
+- implemented in terms of itself, so a configuration using just
+- `posix' cannot be complete.
+-
+-`unix'
+- This is the directory for Unix-like things. *Note Porting to
+- Unix::. `unix' implies `posix'. There are some special-purpose
+- subdirectories of `unix':
+-
+- `unix/common'
+- This directory is for things common to both BSD and System V
+- release 4. Both `unix/bsd' and `unix/sysv/sysv4' imply
+- `unix/common'.
+-
+- `unix/inet'
+- This directory is for `socket' and related functions on Unix
+- systems. `unix/inet/Subdirs' enables the `inet' top-level
+- subdirectory. `unix/common' implies `unix/inet'.
+-
+-`mach'
+- This is the directory for things based on the Mach microkernel
+- from CMU (including the GNU operating system). Other basic
+- operating systems (VMS, for example) would have their own
+- directories at the top level of the `sysdeps' hierarchy, parallel
+- to `unix' and `mach'.

+-
+-Porting the GNU C Library to Unix Systems
+------------------------------------------
+-
+- Most Unix systems are fundamentally very similar. There are
+-variations between different machines, and variations in what
+-facilities are provided by the kernel. But the interface to the
+-operating system facilities is, for the most part, pretty uniform and
+-simple.
+-
+- The code for Unix systems is in the directory `unix', at the top
+-level of the `sysdeps' hierarchy. This directory contains
+-subdirectories (and subdirectory trees) for various Unix variants.
+-
+- The functions which are system calls in most Unix systems are
+-implemented in assembly code, which is generated automatically from
+-specifications in files named `syscalls.list'. There are several such
+-files, one in `sysdeps/unix' and others in its subdirectories. Some
+-special system calls are implemented in files that are named with a
+-suffix of `.S'; for example, `_exit.S'. Files ending in `.S' are run
+-through the C preprocessor before being fed to the assembler.
+-
+- These files all use a set of macros that should be defined in
+-`sysdep.h'. The `sysdep.h' file in `sysdeps/unix' partially defines
+-them; a `sysdep.h' file in another directory must finish defining them
+-for the particular machine and operating system variant. See
+-`sysdeps/unix/sysdep.h' and the machine-specific `sysdep.h'
+-implementations to see what these macros are and what they should do.
+-
+- The system-specific makefile for the `unix' directory
+-(`sysdeps/unix/Makefile') gives rules to generate several files from
+-the Unix system you are building the library on (which is assumed to be
+-the target system you are building the library _for_). All the
+-generated files are put in the directory where the object files are
+-kept; they should not affect the source tree itself. The files
+-generated are `ioctls.h', `errnos.h', `sys/param.h', and `errlist.c'
+-(for the `stdio' section of the library).

+-Contributors to the GNU C Library
+-*********************************
+-
+- The GNU C library was written originally by Roland McGrath, and is
+-currently maintained by Ulrich Drepper. Some parts of the library were
+-contributed or worked on by other people.
+-
+- * The `getopt' function and related code was written by Richard
+- Stallman, David J. MacKenzie, and Roland McGrath.
+-
+- * The merge sort function `qsort' was written by Michael J. Haertel.
+-
+- * The quick sort function used as a fallback by `qsort' was written
+- by Douglas C. Schmidt.
+-
+- * The memory allocation functions `malloc', `realloc' and `free' and
+- related code were written by Michael J. Haertel, Wolfram Gloger,
+- and Doug Lea.
+-
+- * Fast implementations of many of the string functions (`memcpy',
+- `strlen', etc.) were written by Torbjo"rn Granlund.
+-
+- * The `tar.h' header file was written by David J. MacKenzie.
+-
+- * The port to the MIPS DECStation running Ultrix 4
+- (`mips-dec-ultrix4') was contributed by Brendan Kehoe and Ian
+- Lance Taylor.
+-
+- * The DES encryption function `crypt' and related functions were
+- contributed by Michael Glad.
+-
+- * The `ftw' and `nftw' functions were contributed by Ulrich Drepper.
+-
+- * The startup code to support SunOS shared libraries was contributed
+- by Tom Quinn.
+-
+- * The `mktime' function was contributed by Paul Eggert.
+-
+- * The port to the Sequent Symmetry running Dynix version 3
+- (`i386-sequent-bsd') was contributed by Jason Merrill.
+-
+- * The timezone support code is derived from the public-domain
+- timezone package by Arthur David Olson and his many contributors.
+-
+- * The port to the DEC Alpha running OSF/1 (`alpha-dec-osf1') was
+- contributed by Brendan Kehoe, using some code written by Roland
+- McGrath.
+-
+- * The port to SGI machines running Irix 4 (`mips-sgi-irix4') was

+-
+- * The port of the Mach and Hurd code to the MIPS architecture
+- (`mips-ANYTHING-gnu') was contributed by Kazumoto Kojima.
+-
+- * The floating-point printing function used by `printf' and friends
+- and the floating-point reading function used by `scanf', `strtod'
+- and friends were written by Ulrich Drepper. The multi-precision
+- integer functions used in those functions are taken from GNU MP,
+- which was contributed by Torbjo"rn Granlund.
+-
+- * The internationalization support in the library, and the support
+- programs `locale' and `localedef', were written by Ulrich Drepper.
+- Ulrich Drepper adapted the support code for message catalogs
+- (`libintl.h', etc.) from the GNU `gettext' package, which he also
+- wrote. He also contributed the `catgets' support and the entire
+- suite of multi-byte and wide-character support functions
+- (`wctype.h', `wchar.h', etc.).
+-
+- * The implementations of the `nsswitch.conf' mechanism and the files
+- and DNS backends for it were designed and written by Ulrich
+- Drepper and Roland McGrath, based on a backend interface defined
+- by Peter Eriksson.
+-
+- * The port to Linux i386/ELF (`i386-ANYTHING-linux') was contributed
+- by Ulrich Drepper, based in large part on work done in Hongjiu
+- Lu's Linux version of the GNU C Library.
+-
+- * The port to Linux/m68k (`m68k-ANYTHING-linux') was contributed by
+- Andreas Schwab.
+-
+- * The ports to Linux/ARM (`arm-ANYTHING-linuxaout') and ARM
+- standalone (`arm-ANYTHING-none'), as well as parts of the IPv6
+- support code, were contributed by Philip Blundell.
+-
+- * Richard Henderson contributed the ELF dynamic linking code and
+- other support for the Alpha processor.
+-
+- * David Mosberger-Tang contributed the port to Linux/Alpha
+- (`alpha-ANYTHING-linux').

+- argz/envz interfaces.
+-
+- * Stephen R. van den Berg contributed a highly-optimized `strstr'
+- function.
+-
+- * Ulrich Drepper contributed the `hsearch' and `drand48' families of
+- functions; reentrant `...`_r'' versions of the `random' family;
+- System V shared memory and IPC support code; and several
+- highly-optimized string functions for iX86 processors.
+-
+- * The math functions are taken from `fdlibm-5.1' by Sun
+- Microsystems, as modified by J.T. Conklin, Ian Lance Taylor,
+- Ulrich Drepper, Andreas Schwab, and Roland McGrath.
+-
+- * The `libio' library used to implement `stdio' functions on some
+- platforms was written by Per Bothner and modified by Ulrich
+- Drepper.
+-
+- * Eric Youngdale and Ulrich Drepper implemented versioning of
+- objects on the symbol level.
+-
+- * Thorsten Kukuk provided an implementation for NIS (YP) and NIS+,
+- securelevel 0, 1 and 2.
+-
+- * Andreas Jaeger provided a test suite for the math library.
+-
+- * Mark Kettenis implemented the utmpx interface and an utmp daemon.
+-
+- * Ulrich Drepper added character conversion functions (`iconv').
+-
+- * Thorsten Kukuk provided an implementation for a caching daemon for
+- NSS (nscd).
+-
+- * Tim Waugh provided an implementation of the POSIX.2 wordexp
+- function family.
+-
+- * Mark Kettenis provided a Hesiod NSS module.
+-
+- * The Internet-related code (most of the `inet' subdirectory) and
+- several other miscellaneous functions and header files have been
+- included from 4.4 BSD with little or no modification. The copying
+- permission notice for this code can be found in the file `LICENSES'
+- in the source distribution.
+-
+- * The random number generation functions `random', `srandom',
+- `setstate' and `initstate', which are also the basis for the
+- `rand' and `srand' functions, were written by Earl T. Cohen for
+- the University of California at Berkeley and are copyrighted by the
+- Regents of the University of California. They have undergone minor
+- changes to fit into the GNU C library and to fit the ISO C
+- standard, but the functional code is Berkeley's.
+-
+- * The DNS resolver code is taken directly from BIND 4.9.5, which
+- includes copyrighted code from UC Berkeley and from Digital
+- Equipment Corporation. See the file `LICENSES' for the text of
+- the DEC license.
+-
+- * The code to support Sun RPC is taken verbatim from Sun's
+- RPCSRC-4.0 distribution; see the file `LICENSES' for the text of
+- the license.
+-
+- * Some of the support code for Mach is taken from Mach 3.0 by CMU;
+- the file if_ppp.h is also copyright by CMU, but under a different
+- license; see the file `LICENSES' for the text of the licenses.
+-
+- * Many of the IA64 math functions are taken from a collection of
+- "Highly Optimized Mathematical Functions for Itanium" that Intel
+- makes available under a free license; see the file `LICENSES' for
+- details.
+-
+- * The `getaddrinfo' and `getnameinfo' functions and supporting code
+- were written by Craig Metz; see the file `LICENSES' for details on
+- their licensing.
+-
+- * Many of the IEEE 64-bit double precision math functions (in the
+- `sysdeps/ieee754/dbl-64' subdirectory) come from the IBM Accurate
+- Mathematical Library, contributed by IBM.

+-Free Software Needs Free Documentation
+-**************************************
+-
+- The biggest deficiency in the free software community today is not in
+-the software--it is the lack of good free documentation that we can
+-include with the free software. Many of our most important programs do
+-not come with free reference manuals and free introductory texts.
+-Documentation is an essential part of any software package; when an
+-important free software package does not come with a free manual and a
+-free tutorial, that is a major gap. We have many such gaps today.
+-
+- Consider Perl, for instance. The tutorial manuals that people
+-normally use are non-free. How did this come about? Because the
+-authors of those manuals published them with restrictive terms--no
+-copying, no modification, source files not available--which exclude
+-them from the free software world.
+-
+- That wasn't the first time this sort of thing happened, and it was
+-far from the last. Many times we have heard a GNU user eagerly
+-describe a manual that he is writing, his intended contribution to the
+-community, only to learn that he had ruined everything by signing a
+-publication contract to make it non-free.
+-
+- Free documentation, like free software, is a matter of freedom, not
+-price. The problem with the non-free manual is not that publishers
+-charge a price for printed copies--that in itself is fine. (The Free
+-Software Foundation sells printed copies of manuals, too.) The problem
+-is the restrictions on the use of the manual. Free manuals are
+-available in source code form, and give you permission to copy and
+-modify. Non-free manuals do not allow this.
+-
+- The criteria of freedom for a free manual are roughly the same as for
+-free software. Redistribution (including the normal kinds of
+-commercial redistribution) must be permitted, so that the manual can
+-accompany every copy of the program, both on-line and on paper.
+-
+- Permission for modification of the technical content is crucial too.
+-When people modify the software, adding or changing features, if they
+-are conscientious they will change the manual too--so they can provide
+-accurate and clear documentation for the modified program. A manual
+-that leaves you no choice but to write a new manual to document a
+-changed version of the program is not really available to our community.
+-
+- Some kinds of limits on the way modification is handled are
+-acceptable. For example, requirements to preserve the original
+-author's copyright notice, the distribution terms, or the list of
+-authors, are ok. It is also no problem to require modified versions to
+-include notice that they were modified. Even entire sections that may
+-not be deleted or changed are acceptable, as long as they deal with
+-nontechnical topics (like this one). These kinds of restrictions are
+-acceptable because they don't obstruct the community's normal use of
+-the manual.
+-
+- However, it must be possible to modify all the _technical_ content
+-of the manual, and then distribute the result in all the usual media,
+-through all the usual channels. Otherwise, the restrictions obstruct
+-the use of the manual, it is not free, and we need another manual to
+-replace it.
+-
+- Please spread the word about this issue. Our community continues to
+-lose manuals to proprietary publishing. If we spread the word that
+-free software needs free reference manuals and free tutorials, perhaps
+-the next person who wants to contribute by writing documentation will
+-realize, before it is too late, that only free manuals contribute to
+-the free software community.
+-
+- If you are writing documentation, please insist on publishing it
+-under the GNU Free Documentation License or another free documentation
+-license. Remember that this decision requires your approval--you don't
+-have to let the publisher decide. Some commercial publishers will use
+-a free license if you insist, but they will not propose the option; it
+-is up to you to raise the issue and say firmly that this is what you
+-want. If the publisher you are dealing with refuses, please try other
+-publishers. If you're not sure whether a proposed license is free,
+-write to <licensing@gnu.org>.
+-
+- You can encourage commercial publishers to sell more free, copylefted
+-manuals and tutorials by buying them, and particularly by buying copies
+-from the publishers that paid for their writing or for major
+-improvements. Meanwhile, try to avoid buying non-free documentation at
+-all. Check the distribution terms of a manual before you buy it, and
+-insist that whoever seeks your business must respect your freedom.
+-Check the history of the book, and try reward the publishers that have
+-paid or pay the authors to work on it.
+-
+- The Free Software Foundation maintains a list of free documentation
+-published by other publishers, at
+-<http://www.fsf.org/doc/other-free-books.html>.

+-GNU Lesser General Public License
+-*********************************
+-
+- Version 2.1, February 1999
+- Copyright (C) 1991, 1999 Free Software Foundation, Inc.
+- 59 Temple Place -- Suite 330, Boston, MA 02111-1307, USA
+-
+- Everyone is permitted to copy and distribute verbatim copies
+- of this license document, but changing it is not allowed.
+-
+- [This is the first released version of the Lesser GPL. It also counts
+- as the successor of the GNU Library Public License, version 2, hence the
+- version number 2.1.]
+-
+-Preamble
+---------
+-
+- The licenses for most software are designed to take away your
+-freedom to share and change it. By contrast, the GNU General Public
+-Licenses are intended to guarantee your freedom to share and change
+-free software--to make sure the software is free for all its users.
+-
+- This license, the Lesser General Public License, applies to some
+-specially designated software--typically libraries--of the Free
+-Software Foundation and other authors who decide to use it. You can use
+-it too, but we suggest you first think carefully about whether this
+-license or the ordinary General Public License is the better strategy to
+-use in any particular case, based on the explanations below.
+-
+- When we speak of free software, we are referring to freedom of use,
+-not price. Our General Public Licenses are designed to make sure that
+-you have the freedom to distribute copies of free software (and charge
+-for this service if you wish); that you receive source code or can get
+-it if you want it; that you can change the software and use pieces of it
+-in new free programs; and that you are informed that you can do these
+-things.
+-
+- To protect your rights, we need to make restrictions that forbid
+-distributors to deny you these rights or to ask you to surrender these
+-rights. These restrictions translate to certain responsibilities for
+-you if you distribute copies of the library or if you modify it.
+-
+- For example, if you distribute copies of the library, whether gratis
+-or for a fee, you must give the recipients all the rights that we gave
+-you. You must make sure that they, too, receive or can get the source
+-code. If you link other code with the library, you must provide
+-complete object files to the recipients, so that they can relink them
+-with the library after making changes to the library and recompiling
+-it. And you must show them these terms so they know their rights.
+-
+- We protect your rights with a two-step method: (1) we copyright the
+-library, and (2) we offer you this license, which gives you legal
+-permission to copy, distribute and/or modify the library.
+-
+- To protect each distributor, we want to make it very clear that
+-there is no warranty for the free library. Also, if the library is
+-modified by someone else and passed on, the recipients should know that
+-what they have is not the original version, so that the original
+-author's reputation will not be affected by problems that might be
+-introduced by others.
+-
+- Finally, software patents pose a constant threat to the existence of
+-any free program. We wish to make sure that a company cannot
+-effectively restrict the users of a free program by obtaining a
+-restrictive license from a patent holder. Therefore, we insist that
+-any patent license obtained for a version of the library must be
+-consistent with the full freedom of use specified in this license.
+-
+- Most GNU software, including some libraries, is covered by the
+-ordinary GNU General Public License. This license, the GNU Lesser
+-General Public License, applies to certain designated libraries, and is
+-quite different from the ordinary General Public License. We use this
+-license for certain libraries in order to permit linking those
+-libraries into non-free programs.
+-
+- When a program is linked with a library, whether statically or using
+-a shared library, the combination of the two is legally speaking a
+-combined work, a derivative of the original library. The ordinary
+-General Public License therefore permits such linking only if the
+-entire combination fits its criteria of freedom. The Lesser General
+-Public License permits more lax criteria for linking other code with
+-the library.
+-
+- We call this license the "Lesser" General Public License because it
+-does _Less_ to protect the user's freedom than the ordinary General
+-Public License. It also provides other free software developers Less
+-of an advantage over competing non-free programs. These disadvantages
+-are the reason we use the ordinary General Public License for many
+-libraries. However, the Lesser license provides advantages in certain
+-special circumstances.
+-
+- For example, on rare occasions, there may be a special need to
+-encourage the widest possible use of a certain library, so that it
+-becomes a de-facto standard. To achieve this, non-free programs must be
+-allowed to use the library. A more frequent case is that a free
+-library does the same job as widely used non-free libraries. In this
+-case, there is little to gain by limiting the free library to free
+-software only, so we use the Lesser General Public License.
+-
+- In other cases, permission to use a particular library in non-free
+-programs enables a greater number of people to use a large body of free
+-software. For example, permission to use the GNU C Library in non-free
+-programs enables many more people to use the whole GNU operating
+-system, as well as its variant, the GNU/Linux operating system.
+-
+- Although the Lesser General Public License is Less protective of the
+-users' freedom, it does ensure that the user of a program that is
+-linked with the Library has the freedom and the wherewithal to run that
+-program using a modified version of the Library.
+-
+- The precise terms and conditions for copying, distribution and
+-modification follow. Pay close attention to the difference between a
+-"work based on the library" and a "work that uses the library". The
+-former contains code derived from the library, whereas the latter must
+-be combined with the library in order to run.
+-
+- GNU LESSER GENERAL PUBLIC LICENSE
+- TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+- 0. This License Agreement applies to any software library or other
+- program which contains a notice placed by the copyright holder or
+- other authorized party saying it may be distributed under the
+- terms of this Lesser General Public License (also called "this
+- License"). Each licensee is addressed as "you".
+-
+- A "library" means a collection of software functions and/or data
+- prepared so as to be conveniently linked with application programs
+- (which use some of those functions and data) to form executables.
+-
+- The "Library", below, refers to any such software library or work
+- which has been distributed under these terms. A "work based on the
+- Library" means either the Library or any derivative work under
+- copyright law: that is to say, a work containing the Library or a
+- portion of it, either verbatim or with modifications and/or
+- translated straightforwardly into another language. (Hereinafter,
+- translation is included without limitation in the term
+- "modification".)
+-
+- "Source code" for a work means the preferred form of the work for
+- making modifications to it. For a library, complete source code
+- means all the source code for all modules it contains, plus any
+- associated interface definition files, plus the scripts used to
+- control compilation and installation of the library.
+-
+- Activities other than copying, distribution and modification are
+- not covered by this License; they are outside its scope. The act
+- of running a program using the Library is not restricted, and
+- output from such a program is covered only if its contents
+- constitute a work based on the Library (independent of the use of
+- the Library in a tool for writing it). Whether that is true
+- depends on what the Library does and what the program that uses
+- the Library does.
+-
+- 1. You may copy and distribute verbatim copies of the Library's
+- complete source code as you receive it, in any medium, provided
+- that you conspicuously and appropriately publish on each copy an
+- appropriate copyright notice and disclaimer of warranty; keep
+- intact all the notices that refer to this License and to the
+- absence of any warranty; and distribute a copy of this License
+- along with the Library.
+-
+- You may charge a fee for the physical act of transferring a copy,
+- and you may at your option offer warranty protection in exchange
+- for a fee.
+-
+- 2. You may modify your copy or copies of the Library or any portion
+- of it, thus forming a work based on the Library, and copy and
+- distribute such modifications or work under the terms of Section 1
+- above, provided that you also meet all of these conditions:
+-
+- a. The modified work must itself be a software library.
+-
+- b. You must cause the files modified to carry prominent notices
+- stating that you changed the files and the date of any change.
+-
+- c. You must cause the whole of the work to be licensed at no
+- charge to all third parties under the terms of this License.
+-
+- d. If a facility in the modified Library refers to a function or
+- a table of data to be supplied by an application program that
+- uses the facility, other than as an argument passed when the
+- facility is invoked, then you must make a good faith effort
+- to ensure that, in the event an application does not supply
+- such function or table, the facility still operates, and
+- performs whatever part of its purpose remains meaningful.
+-
+- (For example, a function in a library to compute square roots
+- has a purpose that is entirely well-defined independent of the
+- application. Therefore, Subsection 2d requires that any
+- application-supplied function or table used by this function
+- must be optional: if the application does not supply it, the
+- square root function must still compute square roots.)
+-
+- These requirements apply to the modified work as a whole. If
+- identifiable sections of that work are not derived from the
+- Library, and can be reasonably considered independent and separate
+- works in themselves, then this License, and its terms, do not
+- apply to those sections when you distribute them as separate
+- works. But when you distribute the same sections as part of a
+- whole which is a work based on the Library, the distribution of
+- the whole must be on the terms of this License, whose permissions
+- for other licensees extend to the entire whole, and thus to each
+- and every part regardless of who wrote it.
+-
+- Thus, it is not the intent of this section to claim rights or
+- contest your rights to work written entirely by you; rather, the
+- intent is to exercise the right to control the distribution of
+- derivative or collective works based on the Library.
+-
+- In addition, mere aggregation of another work not based on the
+- Library with the Library (or with a work based on the Library) on
+- a volume of a storage or distribution medium does not bring the
+- other work under the scope of this License.
+-
+- 3. You may opt to apply the terms of the ordinary GNU General Public
+- License instead of this License to a given copy of the Library.
+- To do this, you must alter all the notices that refer to this
+- License, so that they refer to the ordinary GNU General Public
+- License, version 2, instead of to this License. (If a newer
+- version than version 2 of the ordinary GNU General Public License
+- has appeared, then you can specify that version instead if you
+- wish.) Do not make any other change in these notices.
+-
+- Once this change is made in a given copy, it is irreversible for
+- that copy, so the ordinary GNU General Public License applies to
+- all subsequent copies and derivative works made from that copy.
+-
+- This option is useful when you wish to copy part of the code of
+- the Library into a program that is not a library.
+-
+- 4. You may copy and distribute the Library (or a portion or
+- derivative of it, under Section 2) in object code or executable
+- form under the terms of Sections 1 and 2 above provided that you
+- accompany it with the complete corresponding machine-readable
+- source code, which must be distributed under the terms of Sections
+- 1 and 2 above on a medium customarily used for software
+- interchange.
+-
+- If distribution of object code is made by offering access to copy
+- from a designated place, then offering equivalent access to copy
+- the source code from the same place satisfies the requirement to
+- distribute the source code, even though third parties are not
+- compelled to copy the source along with the object code.
+-
+- 5. A program that contains no derivative of any portion of the
+- Library, but is designed to work with the Library by being
+- compiled or linked with it, is called a "work that uses the
+- Library". Such a work, in isolation, is not a derivative work of
+- the Library, and therefore falls outside the scope of this License.
+-
+- However, linking a "work that uses the Library" with the Library
+- creates an executable that is a derivative of the Library (because
+- it contains portions of the Library), rather than a "work that
+- uses the library". The executable is therefore covered by this
+- License. Section 6 states terms for distribution of such
+- executables.
+-
+- When a "work that uses the Library" uses material from a header
+- file that is part of the Library, the object code for the work may
+- be a derivative work of the Library even though the source code is
+- not. Whether this is true is especially significant if the work
+- can be linked without the Library, or if the work is itself a
+- library. The threshold for this to be true is not precisely
+- defined by law.
+-
+- If such an object file uses only numerical parameters, data
+- structure layouts and accessors, and small macros and small inline
+- functions (ten lines or less in length), then the use of the object
+- file is unrestricted, regardless of whether it is legally a
+- derivative work. (Executables containing this object code plus
+- portions of the Library will still fall under Section 6.)
+-
+- Otherwise, if the work is a derivative of the Library, you may
+- distribute the object code for the work under the terms of Section
+- 6. Any executables containing that work also fall under Section 6,
+- whether or not they are linked directly with the Library itself.
+-
+- 6. As an exception to the Sections above, you may also combine or
+- link a "work that uses the Library" with the Library to produce a
+- work containing portions of the Library, and distribute that work
+- under terms of your choice, provided that the terms permit
+- modification of the work for the customer's own use and reverse
+- engineering for debugging such modifications.
+-
+- You must give prominent notice with each copy of the work that the
+- Library is used in it and that the Library and its use are covered
+- by this License. You must supply a copy of this License. If the
+- work during execution displays copyright notices, you must include
+- the copyright notice for the Library among them, as well as a
+- reference directing the user to the copy of this License. Also,
+- you must do one of these things:
+-
+- a. Accompany the work with the complete corresponding
+- machine-readable source code for the Library including
+- whatever changes were used in the work (which must be
+- distributed under Sections 1 and 2 above); and, if the work
+- is an executable linked with the Library, with the complete
+- machine-readable "work that uses the Library", as object code
+- and/or source code, so that the user can modify the Library
+- and then relink to produce a modified executable containing
+- the modified Library. (It is understood that the user who
+- changes the contents of definitions files in the Library will
+- not necessarily be able to recompile the application to use
+- the modified definitions.)
+-
+- b. Use a suitable shared library mechanism for linking with the
+- Library. A suitable mechanism is one that (1) uses at run
+- time a copy of the library already present on the user's
+- computer system, rather than copying library functions into
+- the executable, and (2) will operate properly with a modified
+- version of the library, if the user installs one, as long as
+- the modified version is interface-compatible with the version
+- that the work was made with.
+-
+- c. Accompany the work with a written offer, valid for at least
+- three years, to give the same user the materials specified in
+- Subsection 6a, above, for a charge no more than the cost of
+- performing this distribution.
+-
+- d. If distribution of the work is made by offering access to copy
+- from a designated place, offer equivalent access to copy the
+- above specified materials from the same place.
+-
+- e. Verify that the user has already received a copy of these
+- materials or that you have already sent this user a copy.
+-
+- For an executable, the required form of the "work that uses the
+- Library" must include any data and utility programs needed for
+- reproducing the executable from it. However, as a special
+- exception, the materials to be distributed need not include
+- anything that is normally distributed (in either source or binary
+- form) with the major components (compiler, kernel, and so on) of
+- the operating system on which the executable runs, unless that
+- component itself accompanies the executable.
+-
+- It may happen that this requirement contradicts the license
+- restrictions of other proprietary libraries that do not normally
+- accompany the operating system. Such a contradiction means you
+- cannot use both them and the Library together in an executable
+- that you distribute.
+-
+- 7. You may place library facilities that are a work based on the
+- Library side-by-side in a single library together with other
+- library facilities not covered by this License, and distribute
+- such a combined library, provided that the separate distribution
+- of the work based on the Library and of the other library
+- facilities is otherwise permitted, and provided that you do these
+- two things:
+-
+- a. Accompany the combined library with a copy of the same work
+- based on the Library, uncombined with any other library
+- facilities. This must be distributed under the terms of the
+- Sections above.
+-
+- b. Give prominent notice with the combined library of the fact
+- that part of it is a work based on the Library, and explaining
+- where to find the accompanying uncombined form of the same
+- work.
+-
+- 8. You may not copy, modify, sublicense, link with, or distribute the
+- Library except as expressly provided under this License. Any
+- attempt otherwise to copy, modify, sublicense, link with, or
+- distribute the Library is void, and will automatically terminate
+- your rights under this License. However, parties who have
+- received copies, or rights, from you under this License will not
+- have their licenses terminated so long as such parties remain in
+- full compliance.
+-
+- 9. You are not required to accept this License, since you have not
+- signed it. However, nothing else grants you permission to modify
+- or distribute the Library or its derivative works. These actions
+- are prohibited by law if you do not accept this License.
+- Therefore, by modifying or distributing the Library (or any work
+- based on the Library), you indicate your acceptance of this
+- License to do so, and all its terms and conditions for copying,
+- distributing or modifying the Library or works based on it.
+-
+- 10. Each time you redistribute the Library (or any work based on the
+- Library), the recipient automatically receives a license from the
+- original licensor to copy, distribute, link with or modify the
+- Library subject to these terms and conditions. You may not impose
+- any further restrictions on the recipients' exercise of the rights
+- granted herein. You are not responsible for enforcing compliance
+- by third parties with this License.
+-
+- 11. If, as a consequence of a court judgment or allegation of patent
+- infringement or for any other reason (not limited to patent
+- issues), conditions are imposed on you (whether by court order,
+- agreement or otherwise) that contradict the conditions of this
+- License, they do not excuse you from the conditions of this
+- License. If you cannot distribute so as to satisfy simultaneously
+- your obligations under this License and any other pertinent
+- obligations, then as a consequence you may not distribute the
+- Library at all. For example, if a patent license would not permit
+- royalty-free redistribution of the Library by all those who
+- receive copies directly or indirectly through you, then the only
+- way you could satisfy both it and this License would be to refrain
+- entirely from distribution of the Library.
+-
+- If any portion of this section is held invalid or unenforceable
+- under any particular circumstance, the balance of the section is
+- intended to apply, and the section as a whole is intended to apply
+- in other circumstances.
+-
+- It is not the purpose of this section to induce you to infringe any
+- patents or other property right claims or to contest validity of
+- any such claims; this section has the sole purpose of protecting
+- the integrity of the free software distribution system which is
+- implemented by public license practices. Many people have made
+- generous contributions to the wide range of software distributed
+- through that system in reliance on consistent application of that
+- system; it is up to the author/donor to decide if he or she is
+- willing to distribute software through any other system and a
+- licensee cannot impose that choice.
+-
+- This section is intended to make thoroughly clear what is believed
+- to be a consequence of the rest of this License.
+-
+- 12. If the distribution and/or use of the Library is restricted in
+- certain countries either by patents or by copyrighted interfaces,
+- the original copyright holder who places the Library under this
+- License may add an explicit geographical distribution limitation
+- excluding those countries, so that distribution is permitted only
+- in or among countries not thus excluded. In such case, this
+- License incorporates the limitation as if written in the body of
+- this License.
+-
+- 13. The Free Software Foundation may publish revised and/or new
+- versions of the Lesser General Public License from time to time.
+- Such new versions will be similar in spirit to the present version,
+- but may differ in detail to address new problems or concerns.
+-
+- Each version is given a distinguishing version number. If the
+- Library specifies a version number of this License which applies
+- to it and "any later version", you have the option of following
+- the terms and conditions either of that version or of any later
+- version published by the Free Software Foundation. If the Library
+- does not specify a license version number, you may choose any
+- version ever published by the Free Software Foundation.
+-
+- 14. If you wish to incorporate parts of the Library into other free
+- programs whose distribution conditions are incompatible with these,
+- write to the author to ask for permission. For software which is
+- copyrighted by the Free Software Foundation, write to the Free
+- Software Foundation; we sometimes make exceptions for this. Our
+- decision will be guided by the two goals of preserving the free
+- status of all derivatives of our free software and of promoting
+- the sharing and reuse of software generally.
+-
+- NO WARRANTY
+-
+- 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
+- WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE
+- LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+- HOLDERS AND/OR OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT
+- WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT
+- NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND
+- FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE
+- QUALITY AND PERFORMANCE OF THE LIBRARY IS WITH YOU. SHOULD THE
+- LIBRARY PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY
+- SERVICING, REPAIR OR CORRECTION.
+-
+- 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
+- WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY
+- MODIFY AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE
+- LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL,
+- INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR
+- INABILITY TO USE THE LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF
+- DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU
+- OR THIRD PARTIES OR A FAILURE OF THE LIBRARY TO OPERATE WITH ANY
+- OTHER SOFTWARE), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN
+- ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
+-
+- END OF TERMS AND CONDITIONS
+-
+-How to Apply These Terms to Your New Libraries
+-----------------------------------------------
+-
+- If you develop a new library, and you want it to be of the greatest
+-possible use to the public, we recommend making it free software that
+-everyone can redistribute and change. You can do so by permitting
+-redistribution under these terms (or, alternatively, under the terms of
+-the ordinary General Public License).
+-
+- To apply these terms, attach the following notices to the library.
+-It is safest to attach them to the start of each source file to most
+-effectively convey the exclusion of warranty; and each file should have
+-at least the "copyright" line and a pointer to where the full notice is
+-found.
+-
+- ONE LINE TO GIVE THE LIBRARY'S NAME AND AN IDEA OF WHAT IT DOES.
+- Copyright (C) YEAR NAME OF AUTHOR
+-
+- This library is free software; you can redistribute it and/or modify it
+- under the terms of the GNU Lesser General Public License as published by
+- the Free Software Foundation; either version 2.1 of the License, or (at
+- your option) any later version.
+-
+- This library is distributed in the hope that it will be useful, but
+- WITHOUT ANY WARRANTY; without even the implied warranty of
+- MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU
+- Lesser General Public License for more details.
+-
+- You should have received a copy of the GNU Lesser General Public
+- License along with this library; if not, write to the Free Software
+- Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307,
+- USA.
+-
+- Also add information on how to contact you by electronic and paper
+-mail.
+-
+- You should also get your employer (if you work as a programmer) or
+-your school, if any, to sign a "copyright disclaimer" for the library,
+-if necessary. Here is a sample; alter the names:

+- Version 1.1, March 2000
+- Copyright (C) 2000 Free Software Foundation, Inc.
+- 59 Temple Place, Suite 330, Boston, MA 02111-1307, USA
+-
+- Everyone is permitted to copy and distribute verbatim copies
+- of this license document, but changing it is not allowed.
+-
+- 0. PREAMBLE
+-
+- The purpose of this License is to make a manual, textbook, or other
+- written document "free" in the sense of freedom: to assure everyone
+- the effective freedom to copy and redistribute it, with or without
+- modifying it, either commercially or noncommercially. Secondarily,
+- this License preserves for the author and publisher a way to get
+- credit for their work, while not being considered responsible for
+- modifications made by others.
+-
+- This License is a kind of "copyleft", which means that derivative
+- works of the document must themselves be free in the same sense.
+- It complements the GNU General Public License, which is a copyleft
+- license designed for free software.
+-
+- We have designed this License in order to use it for manuals for
+- free software, because free software needs free documentation: a
+- free program should come with manuals providing the same freedoms
+- that the software does. But this License is not limited to
+- software manuals; it can be used for any textual work, regardless
+- of subject matter or whether it is published as a printed book.
+- We recommend this License principally for works whose purpose is
+- instruction or reference.
+-
+- 1. APPLICABILITY AND DEFINITIONS
+-
+- This License applies to any manual or other work that contains a
+- notice placed by the copyright holder saying it can be distributed
+- under the terms of this License. The "Document", below, refers to
+- any such manual or work. Any member of the public is a licensee,
+- and is addressed as "you".
+-
+- A "Modified Version" of the Document means any work containing the
+- Document or a portion of it, either copied verbatim, or with
+- modifications and/or translated into another language.
+-
+- A "Secondary Section" is a named appendix or a front-matter
+- section of the Document that deals exclusively with the
+- relationship of the publishers or authors of the Document to the
+- Document's overall subject (or to related matters) and contains
+- nothing that could fall directly within that overall subject.
+- (For example, if the Document is in part a textbook of
+- mathematics, a Secondary Section may not explain any mathematics.)
+- The relationship could be a matter of historical connection with
+- the subject or with related matters, or of legal, commercial,
+- philosophical, ethical or political position regarding them.
+-
+- The "Invariant Sections" are certain Secondary Sections whose
+- titles are designated, as being those of Invariant Sections, in
+- the notice that says that the Document is released under this
+- License.
+-
+- The "Cover Texts" are certain short passages of text that are
+- listed, as Front-Cover Texts or Back-Cover Texts, in the notice
+- that says that the Document is released under this License.
+-
+- A "Transparent" copy of the Document means a machine-readable copy,
+- represented in a format whose specification is available to the
+- general public, whose contents can be viewed and edited directly
+- and straightforwardly with generic text editors or (for images
+- composed of pixels) generic paint programs or (for drawings) some
+- widely available drawing editor, and that is suitable for input to
+- text formatters or for automatic translation to a variety of
+- formats suitable for input to text formatters. A copy made in an
+- otherwise Transparent file format whose markup has been designed
+- to thwart or discourage subsequent modification by readers is not
+- Transparent. A copy that is not "Transparent" is called "Opaque".
+-
+- Examples of suitable formats for Transparent copies include plain
+- ASCII without markup, Texinfo input format, LaTeX input format,
+- SGML or XML using a publicly available DTD, and
+- standard-conforming simple HTML designed for human modification.
+- Opaque formats include PostScript, PDF, proprietary formats that
+- can be read and edited only by proprietary word processors, SGML
+- or XML for which the DTD and/or processing tools are not generally
+- available, and the machine-generated HTML produced by some word
+- processors for output purposes only.
+-
+- The "Title Page" means, for a printed book, the title page itself,
+- plus such following pages as are needed to hold, legibly, the
+- material this License requires to appear in the title page. For
+- works in formats which do not have any title page as such, "Title
+- Page" means the text near the most prominent appearance of the
+- work's title, preceding the beginning of the body of the text.
+-
+- 2. VERBATIM COPYING
+-
+- You may copy and distribute the Document in any medium, either
+- commercially or noncommercially, provided that this License, the
+- copyright notices, and the license notice saying this License
+- applies to the Document are reproduced in all copies, and that you
+- add no other conditions whatsoever to those of this License. You
+- may not use technical measures to obstruct or control the reading
+- or further copying of the copies you make or distribute. However,
+- you may accept compensation in exchange for copies. If you
+- distribute a large enough number of copies you must also follow
+- the conditions in section 3.
+-
+- You may also lend copies, under the same conditions stated above,
+- and you may publicly display copies.
+-
+- 3. COPYING IN QUANTITY
+-
+- If you publish printed copies of the Document numbering more than
+- 100, and the Document's license notice requires Cover Texts, you
+- must enclose the copies in covers that carry, clearly and legibly,
+- all these Cover Texts: Front-Cover Texts on the front cover, and
+- Back-Cover Texts on the back cover. Both covers must also clearly
+- and legibly identify you as the publisher of these copies. The
+- front cover must present the full title with all words of the
+- title equally prominent and visible. You may add other material
+- on the covers in addition. Copying with changes limited to the
+- covers, as long as they preserve the title of the Document and
+- satisfy these conditions, can be treated as verbatim copying in
+- other respects.
+-
+- If the required texts for either cover are too voluminous to fit
+- legibly, you should put the first ones listed (as many as fit
+- reasonably) on the actual cover, and continue the rest onto
+- adjacent pages.
+-
+- If you publish or distribute Opaque copies of the Document
+- numbering more than 100, you must either include a
+- machine-readable Transparent copy along with each Opaque copy, or
+- state in or with each Opaque copy a publicly-accessible
+- computer-network location containing a complete Transparent copy
+- of the Document, free of added material, which the general
+- network-using public has access to download anonymously at no
+- charge using public-standard network protocols. If you use the
+- latter option, you must take reasonably prudent steps, when you
+- begin distribution of Opaque copies in quantity, to ensure that
+- this Transparent copy will remain thus accessible at the stated
+- location until at least one year after the last time you
+- distribute an Opaque copy (directly or through your agents or
+- retailers) of that edition to the public.
+-
+- It is requested, but not required, that you contact the authors of
+- the Document well before redistributing any large number of
+- copies, to give them a chance to provide you with an updated
+- version of the Document.
+-
+- 4. MODIFICATIONS
+-
+- You may copy and distribute a Modified Version of the Document
+- under the conditions of sections 2 and 3 above, provided that you
+- release the Modified Version under precisely this License, with
+- the Modified Version filling the role of the Document, thus
+- licensing distribution and modification of the Modified Version to
+- whoever possesses a copy of it. In addition, you must do these
+- things in the Modified Version:
+-
+- A. Use in the Title Page (and on the covers, if any) a title
+- distinct from that of the Document, and from those of
+- previous versions (which should, if there were any, be listed
+- in the History section of the Document). You may use the
+- same title as a previous version if the original publisher of
+- that version gives permission.
+-
+- B. List on the Title Page, as authors, one or more persons or
+- entities responsible for authorship of the modifications in
+- the Modified Version, together with at least five of the
+- principal authors of the Document (all of its principal
+- authors, if it has less than five).
+-
+- C. State on the Title page the name of the publisher of the
+- Modified Version, as the publisher.
+-
+- D. Preserve all the copyright notices of the Document.
+-
+- E. Add an appropriate copyright notice for your modifications
+- adjacent to the other copyright notices.
+-
+- F. Include, immediately after the copyright notices, a license
+- notice giving the public permission to use the Modified
+- Version under the terms of this License, in the form shown in
+- the Addendum below.
+-
+- G. Preserve in that license notice the full lists of Invariant
+- Sections and required Cover Texts given in the Document's
+- license notice.
+-
+- H. Include an unaltered copy of this License.
+-
+- I. Preserve the section entitled "History", and its title, and
+- add to it an item stating at least the title, year, new
+- authors, and publisher of the Modified Version as given on
+- the Title Page. If there is no section entitled "History" in
+- the Document, create one stating the title, year, authors,
+- and publisher of the Document as given on its Title Page,
+- then add an item describing the Modified Version as stated in
+- the previous sentence.
+-
+- J. Preserve the network location, if any, given in the Document
+- for public access to a Transparent copy of the Document, and
+- likewise the network locations given in the Document for
+- previous versions it was based on. These may be placed in
+- the "History" section. You may omit a network location for a
+- work that was published at least four years before the
+- Document itself, or if the original publisher of the version
+- it refers to gives permission.
+-
+- K. In any section entitled "Acknowledgments" or "Dedications",
+- preserve the section's title, and preserve in the section all
+- the substance and tone of each of the contributor
+- acknowledgments and/or dedications given therein.
+-
+- L. Preserve all the Invariant Sections of the Document,
+- unaltered in their text and in their titles. Section numbers
+- or the equivalent are not considered part of the section
+- titles.
+-
+- M. Delete any section entitled "Endorsements". Such a section
+- may not be included in the Modified Version.
+-
+- N. Do not retitle any existing section as "Endorsements" or to
+- conflict in title with any Invariant Section.
+-
+- If the Modified Version includes new front-matter sections or
+- appendices that qualify as Secondary Sections and contain no
+- material copied from the Document, you may at your option
+- designate some or all of these sections as invariant. To do this,
+- add their titles to the list of Invariant Sections in the Modified
+- Version's license notice. These titles must be distinct from any
+- other section titles.
+-
+- You may add a section entitled "Endorsements", provided it contains
+- nothing but endorsements of your Modified Version by various
+- parties--for example, statements of peer review or that the text
+- has been approved by an organization as the authoritative
+- definition of a standard.
+-
+- You may add a passage of up to five words as a Front-Cover Text,
+- and a passage of up to 25 words as a Back-Cover Text, to the end
+- of the list of Cover Texts in the Modified Version. Only one
+- passage of Front-Cover Text and one of Back-Cover Text may be
+- added by (or through arrangements made by) any one entity. If the
+- Document already includes a cover text for the same cover,
+- previously added by you or by arrangement made by the same entity
+- you are acting on behalf of, you may not add another; but you may
+- replace the old one, on explicit permission from the previous
+- publisher that added the old one.
+-
+- The author(s) and publisher(s) of the Document do not by this
+- License give permission to use their names for publicity for or to
+- assert or imply endorsement of any Modified Version.
+-
+- 5. COMBINING DOCUMENTS
+-
+- You may combine the Document with other documents released under
+- this License, under the terms defined in section 4 above for
+- modified versions, provided that you include in the combination
+- all of the Invariant Sections of all of the original documents,
+- unmodified, and list them all as Invariant Sections of your
+- combined work in its license notice.
+-
+- The combined work need only contain one copy of this License, and
+- multiple identical Invariant Sections may be replaced with a single
+- copy. If there are multiple Invariant Sections with the same name
+- but different contents, make the title of each such section unique
+- by adding at the end of it, in parentheses, the name of the
+- original author or publisher of that section if known, or else a
+- unique number. Make the same adjustment to the section titles in
+- the list of Invariant Sections in the license notice of the
+- combined work.
+-
+- In the combination, you must combine any sections entitled
+- "History" in the various original documents, forming one section
+- entitled "History"; likewise combine any sections entitled
+- "Acknowledgments", and any sections entitled "Dedications". You
+- must delete all sections entitled "Endorsements."
+-
+- 6. COLLECTIONS OF DOCUMENTS
+-
+- You may make a collection consisting of the Document and other
+- documents released under this License, and replace the individual
+- copies of this License in the various documents with a single copy
+- that is included in the collection, provided that you follow the
+- rules of this License for verbatim copying of each of the
+- documents in all other respects.
+-
+- You may extract a single document from such a collection, and
+- distribute it individually under this License, provided you insert
+- a copy of this License into the extracted document, and follow
+- this License in all other respects regarding verbatim copying of
+- that document.
+-
+- 7. AGGREGATION WITH INDEPENDENT WORKS
+-
+- A compilation of the Document or its derivatives with other
+- separate and independent documents or works, in or on a volume of
+- a storage or distribution medium, does not as a whole count as a
+- Modified Version of the Document, provided no compilation
+- copyright is claimed for the compilation. Such a compilation is
+- called an "aggregate", and this License does not apply to the
+- other self-contained works thus compiled with the Document, on
+- account of their being thus compiled, if they are not themselves
+- derivative works of the Document.
+-
+- If the Cover Text requirement of section 3 is applicable to these
+- copies of the Document, then if the Document is less than one
+- quarter of the entire aggregate, the Document's Cover Texts may be
+- placed on covers that surround only the Document within the
+- aggregate. Otherwise they must appear on covers around the whole
+- aggregate.
+-
+- 8. TRANSLATION
+-
+- Translation is considered a kind of modification, so you may
+- distribute translations of the Document under the terms of section
+- 4. Replacing Invariant Sections with translations requires special
+- permission from their copyright holders, but you may include
+- translations of some or all Invariant Sections in addition to the
+- original versions of these Invariant Sections. You may include a
+- translation of this License provided that you also include the
+- original English version of this License. In case of a
+- disagreement between the translation and the original English
+- version of this License, the original English version will prevail.
+-
+- 9. TERMINATION
+-
+- You may not copy, modify, sublicense, or distribute the Document
+- except as expressly provided for under this License. Any other
+- attempt to copy, modify, sublicense or distribute the Document is
+- void, and will automatically terminate your rights under this
+- License. However, parties who have received copies, or rights,
+- from you under this License will not have their licenses
+- terminated so long as such parties remain in full compliance.
+-
+- 10. FUTURE REVISIONS OF THIS LICENSE
+-
+- The Free Software Foundation may publish new, revised versions of
+- the GNU Free Documentation License from time to time. Such new
+- versions will be similar in spirit to the present version, but may
+- differ in detail to address new problems or concerns. See
+- `http://www.gnu.org/copyleft/'.
+-
+- Each version of the License is given a distinguishing version
+- number. If the Document specifies that a particular numbered
+- version of this License "or any later version" applies to it, you
+- have the option of following the terms and conditions either of
+- that specified version or of any later version that has been
+- published (not as a draft) by the Free Software Foundation. If
+- the Document does not specify a version number of this License,
+- you may choose any version ever published (not as a draft) by the
+- Free Software Foundation.
+-
+-ADDENDUM: How to use this License for your documents
+-----------------------------------------------------
+-
+- To use this License in a document you have written, include a copy of
+-the License in the document and put the following copyright and license
+-notices just after the title page:
+-
+- Copyright (C) YEAR YOUR NAME.
+- Permission is granted to copy, distribute and/or modify this document
+- under the terms of the GNU Free Documentation License, Version 1.1
+- or any later version published by the Free Software Foundation;
+- with the Invariant Sections being LIST THEIR TITLES, with the
+- Front-Cover Texts being LIST, and with the Back-Cover Texts being LIST.
+- A copy of the license is included in the section entitled ``GNU
+- Free Documentation License''.
+-
+- If you have no Invariant Sections, write "with no Invariant Sections"
+-instead of saying which ones are invariant. If you have no Front-Cover
+-Texts, write "no Front-Cover Texts" instead of "Front-Cover Texts being
+-LIST"; likewise for Back-Cover Texts.
+-
+- If your document contains nontrivial examples of program code, we
+-recommend releasing these examples in parallel under your choice of
+-free software license, such as the GNU General Public License, to
+-permit their use in free software.

+-Character class determination for wide characters
+-=================================================
+-
+- Amendment 1 to ISO C90 defines functions to classify wide
+-characters. Although the original ISO C90 standard already defined the
+-type `wchar_t', no functions operating on them were defined.
+-
+- The general design of the classification functions for wide
+-characters is more general. It allows extensions to the set of
+-available classifications, beyond those which are always available.
+-The POSIX standard specifies how extensions can be made, and this is
+-already implemented in the GNU C library implementation of the
+-`localedef' program.
+-
+- The character class functions are normally implemented with bitsets,
+-with a bitset per character. For a given character, the appropriate
+-bitset is read from a table and a test is performed as to whether a
+-certain bit is set. Which bit is tested for is determined by the class.
+-
+- For the wide character classification functions this is made visible.
+-There is a type classification type defined, a function to retrieve this
+-value for a given class, and a function to test whether a given
+-character is in this class, using the classification value. On top of
+-this the normal character classification functions as used for `char'
+-objects can be defined.
+-
+- - Data type: wctype_t
+- The `wctype_t' can hold a value which represents a character class.
+- The only defined way to generate such a value is by using the
+- `wctype' function.
+-
+- This type is defined in `wctype.h'.
+-
+- - Function: wctype_t wctype (const char *PROPERTY)
+- The `wctype' returns a value representing a class of wide
+- characters which is identified by the string PROPERTY. Beside
+- some standard properties each locale can define its own ones. In
+- case no property with the given name is known for the current
+- locale selected for the `LC_CTYPE' category, the function returns
+- zero.
+-
+- The properties known in every locale are:
+-
+- `"alnum"' `"alpha"' `"cntrl"' `"digit"'
+- `"graph"' `"lower"' `"print"' `"punct"'
+- `"space"' `"upper"' `"xdigit"'
+-
+- This function is declared in `wctype.h'.
+-
+- To test the membership of a character to one of the non-standard
+-classes the ISO C standard defines a completely new function.
+-
+- - Function: int iswctype (wint_t WC, wctype_t DESC)
+- This function returns a nonzero value if WC is in the character
+- class specified by DESC. DESC must previously be returned by a
+- successful call to `wctype'.
+-
+- This function is declared in `wctype.h'.
+-
+- To make it easier to use the commonly-used classification functions,
+-they are defined in the C library. There is no need to use `wctype' if
+-the property string is one of the known character classes. In some
+-situations it is desirable to construct the property strings, and then
+-it is important that `wctype' can also handle the standard classes.
+-
+- - Function: int iswalnum (wint_t WC)
+- This function returns a nonzero value if WC is an alphanumeric
+- character (a letter or number); in other words, if either
+- `iswalpha' or `iswdigit' is true of a character, then `iswalnum'
+- is also true.
+-
+- This function can be implemented using
+-
+- iswctype (wc, wctype ("alnum"))
+-
+- It is declared in `wctype.h'.
+-
+- - Function: int iswalpha (wint_t WC)
+- Returns true if WC is an alphabetic character (a letter). If
+- `iswlower' or `iswupper' is true of a character, then `iswalpha'
+- is also true.
+-
+- In some locales, there may be additional characters for which
+- `iswalpha' is true--letters which are neither upper case nor lower
+- case. But in the standard `"C"' locale, there are no such
+- additional characters.
+-
+- This function can be implemented using
+-
+- iswctype (wc, wctype ("alpha"))
+-
+- It is declared in `wctype.h'.
+-
+- - Function: int iswcntrl (wint_t WC)
+- Returns true if WC is a control character (that is, a character
+- that is not a printing character).
+-
+- This function can be implemented using
+-
+- iswctype (wc, wctype ("cntrl"))
+-
+- It is declared in `wctype.h'.
+-
+- - Function: int iswdigit (wint_t WC)
+- Returns true if WC is a digit (e.g., `0' through `9'). Please
+- note that this function does not only return a nonzero value for
+- _decimal_ digits, but for all kinds of digits. A consequence is
+- that code like the following will *not* work unconditionally for
+- wide characters:
+-
+- n = 0;
+- while (iswdigit (*wc))
+- {
+- n *= 10;
+- n += *wc++ - L'0';
+- }
+-
+- This function can be implemented using
+-
+- iswctype (wc, wctype ("digit"))
+-
+- It is declared in `wctype.h'.
+-
+- - Function: int iswgraph (wint_t WC)
+- Returns true if WC is a graphic character; that is, a character
+- that has a glyph associated with it. The whitespace characters
+- are not considered graphic.
+-
+- This function can be implemented using
+-
+- iswctype (wc, wctype ("graph"))
+-
+- It is declared in `wctype.h'.
+-
+- - Function: int iswlower (wint_t WC)
+- Returns true if WC is a lower-case letter. The letter need not be
+- from the Latin alphabet, any alphabet representable is valid.
+-
+- This function can be implemented using
+-
+- iswctype (wc, wctype ("lower"))
+-
+- It is declared in `wctype.h'.
+-
+- - Function: int iswprint (wint_t WC)
+- Returns true if WC is a printing character. Printing characters
+- include all the graphic characters, plus the space (` ') character.
+-
+- This function can be implemented using
+-
+- iswctype (wc, wctype ("print"))
+-
+- It is declared in `wctype.h'.
+-
+- - Function: int iswpunct (wint_t WC)
+- Returns true if WC is a punctuation character. This means any
+- printing character that is not alphanumeric or a space character.
+-
+- This function can be implemented using
+-
+- iswctype (wc, wctype ("punct"))
+-
+- It is declared in `wctype.h'.
+-
+- - Function: int iswspace (wint_t WC)
+- Returns true if WC is a "whitespace" character. In the standard
+- `"C"' locale, `iswspace' returns true for only the standard
+- whitespace characters:
+-
+- `L' ''
+- space
+-
+- `L'\f''
+- formfeed
+-
+- `L'\n''
+- newline
+-
+- `L'\r''
+- carriage return
+-
+- `L'\t''
+- horizontal tab
+-
+- `L'\v''
+- vertical tab
+-
+- This function can be implemented using
+-
+- iswctype (wc, wctype ("space"))
+-
+- It is declared in `wctype.h'.
+-
+- - Function: int iswupper (wint_t WC)
+- Returns true if WC is an upper-case letter. The letter need not be
+- from the Latin alphabet, any alphabet representable is valid.
+-
+- This function can be implemented using
+-
+- iswctype (wc, wctype ("upper"))
+-
+- It is declared in `wctype.h'.
+-
+- - Function: int iswxdigit (wint_t WC)
+- Returns true if WC is a hexadecimal digit. Hexadecimal digits
+- include the normal decimal digits `0' through `9' and the letters
+- `A' through `F' and `a' through `f'.
+-
+- This function can be implemented using
+-
+- iswctype (wc, wctype ("xdigit"))
+-
+- It is declared in `wctype.h'.
+-
+- The GNU C library also provides a function which is not defined in
+-the ISO C standard but which is available as a version for single byte
+-characters as well.
+-
+- - Function: int iswblank (wint_t WC)
+- Returns true if WC is a blank character; that is, a space or a tab.
+- This function is a GNU extension. It is declared in `wchar.h'.

+-
+-Notes on using the wide character classes
+-=========================================
+-
+- The first note is probably not astonishing but still occasionally a
+-cause of problems. The `iswXXX' functions can be implemented using
+-macros and in fact, the GNU C library does this. They are still
+-available as real functions but when the `wctype.h' header is included
+-the macros will be used. This is the same as the `char' type versions
+-of these functions.
+-
+- The second note covers something new. It can be best illustrated by
+-a (real-world) example. The first piece of code is an excerpt from the
+-original code. It is truncated a bit but the intention should be clear.
+-
+- int
+- is_in_class (int c, const char *class)
+- {
+- if (strcmp (class, "alnum") == 0)
+- return isalnum (c);
+- if (strcmp (class, "alpha") == 0)
+- return isalpha (c);
+- if (strcmp (class, "cntrl") == 0)
+- return iscntrl (c);
+- ...
+- return 0;
+- }
+-
+- Now, with the `wctype' and `iswctype' you can avoid the `if'
+-cascades, but rewriting the code as follows is wrong:
+-
+- int
+- is_in_class (int c, const char *class)
+- {
+- wctype_t desc = wctype (class);
+- return desc ? iswctype ((wint_t) c, desc) : 0;
+- }
+-
+- The problem is that it is not guaranteed that the wide character
+-representation of a single-byte character can be found using casting.
+-In fact, usually this fails miserably. The correct solution to this
+-problem is to write the code as follows:
+-
+- int
+- is_in_class (int c, const char *class)
+- {
+- wctype_t desc = wctype (class);
+- return desc ? iswctype (btowc (c), desc) : 0;
+- }
+-
+- *Note Converting a Character::, for more information on `btowc'.
+-Note that this change probably does not improve the performance of the
+-program a lot since the `wctype' function still has to make the string
+-comparisons. It gets really interesting if the `is_in_class' function
+-is called more than once for the same class name. In this case the
+-variable DESC could be computed once and reused for all the calls.
+-Therefore the above form of the function is probably not the final one.

+-Mapping of wide characters.
+-===========================
+-
+- The classification functions are also generalized by the ISO C
+-standard. Instead of just allowing the two standard mappings, a locale
+-can contain others. Again, the `localedef' program already supports
+-generating such locale data files.
+-
+- - Data Type: wctrans_t
+- This data type is defined as a scalar type which can hold a value
+- representing the locale-dependent character mapping. There is no
+- way to construct such a value apart from using the return value of
+- the `wctrans' function.
+-
+- This type is defined in `wctype.h'.
+-
+- - Function: wctrans_t wctrans (const char *PROPERTY)
+- The `wctrans' function has to be used to find out whether a named
+- mapping is defined in the current locale selected for the
+- `LC_CTYPE' category. If the returned value is non-zero, you can
+- use it afterwards in calls to `towctrans'. If the return value is
+- zero no such mapping is known in the current locale.
+-
+- Beside locale-specific mappings there are two mappings which are
+- guaranteed to be available in every locale:
+-
+- `"tolower"' `"toupper"'
+-
+- These functions are declared in `wctype.h'.
+-
+- - Function: wint_t towctrans (wint_t WC, wctrans_t DESC)
+- `towctrans' maps the input character WC according to the rules of
+- the mapping for which DESC is a descriptor, and returns the value
+- it finds. DESC must be obtained by a successful call to `wctrans'.
+-
+- This function is declared in `wctype.h'.
+-
+- For the generally available mappings, the ISO C standard defines
+-convenient shortcuts so that it is not necessary to call `wctrans' for
+-them.
+-
+- - Function: wint_t towlower (wint_t WC)
+- If WC is an upper-case letter, `towlower' returns the corresponding
+- lower-case letter. If WC is not an upper-case letter, WC is
+- returned unchanged.
+-
+- `towlower' can be implemented using
+-
+- towctrans (wc, wctrans ("tolower"))
+-
+- This function is declared in `wctype.h'.
+-
+- - Function: wint_t towupper (wint_t WC)
+- If WC is a lower-case letter, `towupper' returns the corresponding
+- upper-case letter. Otherwise WC is returned unchanged.
+-
+- `towupper' can be implemented using
+-
+- towctrans (wc, wctrans ("toupper"))
+-
+- This function is declared in `wctype.h'.
+-
+- The same warnings given in the last section for the use of the wide
+-character classification functions apply here. It is not possible to
+-simply cast a `char' type value to a `wint_t' and use it as an argument
+-to `towctrans' calls.

+-String and Array Utilities
+-**************************
+-
+- Operations on strings (or arrays of characters) are an important
+-part of many programs. The GNU C library provides an extensive set of
+-string utility functions, including functions for copying,
+-concatenating, comparing, and searching strings. Many of these
+-functions can also operate on arbitrary regions of storage; for
+-example, the `memcpy' function can be used to copy the contents of any
+-kind of array.
+-
+- It's fairly common for beginning C programmers to "reinvent the
+-wheel" by duplicating this functionality in their own code, but it pays
+-to become familiar with the library functions and to make use of them,
+-since this offers benefits in maintenance, efficiency, and portability.
+-
+- For instance, you could easily compare one string to another in two
+-lines of C code, but if you use the built-in `strcmp' function, you're
+-less likely to make a mistake. And, since these library functions are
+-typically highly optimized, your program may run faster too.

+-Representation of Strings
+-=========================
+-
+- This section is a quick summary of string concepts for beginning C
+-programmers. It describes how character strings are represented in C
+-and some common pitfalls. If you are already familiar with this
+-material, you can skip this section.
+-
+- A "string" is an array of `char' objects. But string-valued
+-variables are usually declared to be pointers of type `char *'. Such
+-variables do not include space for the text of a string; that has to be
+-stored somewhere else--in an array variable, a string constant, or
+-dynamically allocated memory (*note Memory Allocation::). It's up to
+-you to store the address of the chosen memory space into the pointer
+-variable. Alternatively you can store a "null pointer" in the pointer
+-variable. The null pointer does not point anywhere, so attempting to
+-reference the string it points to gets an error.
+-
+- "string" normally refers to multibyte character strings as opposed to
+-wide character strings. Wide character strings are arrays of type
+-`wchar_t' and as for multibyte character strings usually pointers of
+-type `wchar_t *' are used.
+-
+- By convention, a "null character", `'\0'', marks the end of a
+-multibyte character string and the "null wide character", `L'\0'',
+-marks the end of a wide character string. For example, in testing to
+-see whether the `char *' variable P points to a null character marking
+-the end of a string, you can write `!*P' or `*P == '\0''.
+-
+- A null character is quite different conceptually from a null pointer,
+-although both are represented by the integer `0'.
+-
+- "String literals" appear in C program source as strings of
+-characters between double-quote characters (`"') where the initial
+-double-quote character is immediately preceded by a capital `L' (ell)
+-character (as in `L"foo"'). In ISO C, string literals can also be
+-formed by "string concatenation": `"a" "b"' is the same as `"ab"'. For
+-wide character strings one can either use `L"a" L"b"' or `L"a" "b"'.
+-Modification of string literals is not allowed by the GNU C compiler,
+-because literals are placed in read-only storage.
+-
+- Character arrays that are declared `const' cannot be modified
+-either. It's generally good style to declare non-modifiable string
+-pointers to be of type `const char *', since this often allows the C
+-compiler to detect accidental modifications as well as providing some
+-amount of documentation about what your program intends to do with the
+-string.
+-
+- The amount of memory allocated for the character array may extend
+-past the null character that normally marks the end of the string. In
+-this document, the term "allocated size" is always used to refer to the
+-total amount of memory allocated for the string, while the term
+-"length" refers to the number of characters up to (but not including)
+-the terminating null character.
+-
+- A notorious source of program bugs is trying to put more characters
+-in a string than fit in its allocated size. When writing code that
+-extends strings or moves characters into a pre-allocated array, you
+-should be very careful to keep track of the length of the text and make
+-explicit checks for overflowing the array. Many of the library
+-functions _do not_ do this for you! Remember also that you need to
+-allocate an extra byte to hold the null character that marks the end of
+-the string.
+-
+- Originally strings were sequences of bytes where each byte
+-represents a single character. This is still true today if the strings
+-are encoded using a single-byte character encoding. Things are
+-different if the strings are encoded using a multibyte encoding (for
+-more information on encodings see *Note Extended Char Intro::). There
+-is no difference in the programming interface for these two kind of
+-strings; the programmer has to be aware of this and interpret the byte
+-sequences accordingly.
+-
+- But since there is no separate interface taking care of these
+-differences the byte-based string functions are sometimes hard to use.
+-Since the count parameters of these functions specify bytes a call to
+-`strncpy' could cut a multibyte character in the middle and put an
+-incomplete (and therefore unusable) byte sequence in the target buffer.
+-
+- To avoid these problems later versions of the ISO C standard
+-introduce a second set of functions which are operating on "wide
+-characters" (*note Extended Char Intro::). These functions don't have
+-the problems the single-byte versions have since every wide character is
+-a legal, interpretable value. This does not mean that cutting wide
+-character strings at arbitrary points is without problems. It normally
+-is for alphabet-based languages (except for non-normalized text) but
+-languages based on syllables still have the problem that more than one
+-wide character is necessary to complete a logical unit. This is a
+-higher level problem which the C library functions are not designed to
+-solve. But it is at least good that no invalid byte sequences can be
+-created. Also, the higher level functions can also much easier operate
+-on wide character than on multibyte characters so that a general advise
+-is to use wide characters internally whenever text is more than simply
+-copied.
+-
+- The remaining of this chapter will discuss the functions for handling
+-wide character strings in parallel with the discussion of the multibyte
+-character strings since there is almost always an exact equivalent
+-available.

+-
+-String and Array Conventions
+-============================
+-
+- This chapter describes both functions that work on arbitrary arrays
+-or blocks of memory, and functions that are specific to null-terminated
+-arrays of characters and wide characters.
+-
+- Functions that operate on arbitrary blocks of memory have names
+-beginning with `mem' and `wmem' (such as `memcpy' and `wmemcpy') and
+-invariably take an argument which specifies the size (in bytes and wide
+-characters respectively) of the block of memory to operate on. The
+-array arguments and return values for these functions have type `void
+-*' or `wchar_t'. As a matter of style, the elements of the arrays used
+-with the `mem' functions are referred to as "bytes". You can pass any
+-kind of pointer to these functions, and the `sizeof' operator is useful
+-in computing the value for the size argument. Parameters to the `wmem'
+-functions must be of type `wchar_t *'. These functions are not really
+-usable with anything but arrays of this type.
+-
+- In contrast, functions that operate specifically on strings and wide
+-character strings have names beginning with `str' and `wcs'
+-respectively (such as `strcpy' and `wcscpy') and look for a null
+-character to terminate the string instead of requiring an explicit size
+-argument to be passed. (Some of these functions accept a specified
+-maximum length, but they also check for premature termination with a
+-null character.) The array arguments and return values for these
+-functions have type `char *' and `wchar_t *' respectively, and the
+-array elements are referred to as "characters" and "wide characters".
+-
+- In many cases, there are both `mem' and `str'/`wcs' versions of a
+-function. The one that is more appropriate to use depends on the exact
+-situation. When your program is manipulating arbitrary arrays or
+-blocks of storage, then you should always use the `mem' functions. On
+-the other hand, when you are manipulating null-terminated strings it is
+-usually more convenient to use the `str'/`wcs' functions, unless you
+-already know the length of the string in advance. The `wmem' functions
+-should be used for wide character arrays with known size.
+-
+- Some of the memory and string functions take single characters as
+-arguments. Since a value of type `char' is automatically promoted into
+-an value of type `int' when used as a parameter, the functions are
+-declared with `int' as the type of the parameter in question. In case
+-of the wide character function the situation is similarly: the
+-parameter type for a single wide character is `wint_t' and not
+-`wchar_t'. This would for many implementations not be necessary since
+-the `wchar_t' is large enough to not be automatically promoted, but
+-since the ISO C standard does not require such a choice of types the
+-`wint_t' type is used.

+-
+-String Length
+-=============
+-
+- You can get the length of a string using the `strlen' function.
+-This function is declared in the header file `string.h'.
+-
+- - Function: size_t strlen (const char *S)
+- The `strlen' function returns the length of the null-terminated
+- string S in bytes. (In other words, it returns the offset of the
+- terminating null character within the array.)
+-
+- For example,
+- strlen ("hello, world")
+- => 12
+-
+- When applied to a character array, the `strlen' function returns
+- the length of the string stored there, not its allocated size.
+- You can get the allocated size of the character array that holds a
+- string using the `sizeof' operator:
+-
+- char string[32] = "hello, world";
+- sizeof (string)
+- => 32
+- strlen (string)
+- => 12
+-
+- But beware, this will not work unless STRING is the character
+- array itself, not a pointer to it. For example:
+-
+- char string[32] = "hello, world";
+- char *ptr = string;
+- sizeof (string)
+- => 32
+- sizeof (ptr)
+- => 4 /* (on a machine with 4 byte pointers) */
+-
+- This is an easy mistake to make when you are working with
+- functions that take string arguments; those arguments are always
+- pointers, not arrays.
+-
+- It must also be noted that for multibyte encoded strings the return
+- value does not have to correspond to the number of characters in
+- the string. To get this value the string can be converted to wide
+- characters and `wcslen' can be used or something like the following
+- code can be used:
+-
+- /* The input is in `string'.
+- The length is expected in `n'. */
+- {
+- mbstate_t t;
+- char *scopy = string;
+- /* In initial state. */
+- memset (&t, '\0', sizeof (t));
+- /* Determine number of characters. */
+- n = mbsrtowcs (NULL, &scopy, strlen (scopy), &t);
+- }
+-
+- This is cumbersome to do so if the number of characters (as
+- opposed to bytes) is needed often it is better to work with wide
+- characters.
+-
+- The wide character equivalent is declared in `wchar.h'.
+-
+- - Function: size_t wcslen (const wchar_t *WS)
+- The `wcslen' function is the wide character equivalent to
+- `strlen'. The return value is the number of wide characters in the
+- wide character string pointed to by WS (this is also the offset of
+- the terminating null wide character of WS).
+-
+- Since there are no multi wide character sequences making up one
+- character the return value is not only the offset in the array, it
+- is also the number of wide characters.
+-
+- This function was introduced in Amendment 1 to ISO C90.
+-
+- - Function: size_t strnlen (const char *S, size_t MAXLEN)
+- The `strnlen' function returns the length of the string S in bytes
+- if this length is smaller than MAXLEN bytes. Otherwise it returns
+- MAXLEN. Therefore this function is equivalent to `(strlen (S) < n
+- ? strlen (S) : MAXLEN)' but it is more efficient and works even if
+- the string S is not null-terminated.
+-
+- char string[32] = "hello, world";
+- strnlen (string, 32)
+- => 12
+- strnlen (string, 5)
+- => 5
+-
+- This function is a GNU extension and is declared in `string.h'.
+-
+- - Function: size_t wcsnlen (const wchar_t *WS, size_t MAXLEN)
+- `wcsnlen' is the wide character equivalent to `strnlen'. The
+- MAXLEN parameter specifies the maximum number of wide characters.
+-
+- This function is a GNU extension and is declared in `wchar.h'.

+-
+-Copying and Concatenation
+-=========================
+-
+- You can use the functions described in this section to copy the
+-contents of strings and arrays, or to append the contents of one string
+-to another. The `str' and `mem' functions are declared in the header
+-file `string.h' while the `wstr' and `wmem' functions are declared in
+-the file `wchar.h'.
+-
+- A helpful way to remember the ordering of the arguments to the
+-functions in this section is that it corresponds to an assignment
+-expression, with the destination array specified to the left of the
+-source array. All of these functions return the address of the
+-destination array.
+-
+- Most of these functions do not work properly if the source and
+-destination arrays overlap. For example, if the beginning of the
+-destination array overlaps the end of the source array, the original
+-contents of that part of the source array may get overwritten before it
+-is copied. Even worse, in the case of the string functions, the null
+-character marking the end of the string may be lost, and the copy
+-function might get stuck in a loop trashing all the memory allocated to
+-your program.
+-
+- All functions that have problems copying between overlapping arrays
+-are explicitly identified in this manual. In addition to functions in
+-this section, there are a few others like `sprintf' (*note Formatted
+-Output Functions::) and `scanf' (*note Formatted Input Functions::).
+-
+- - Function: void * memcpy (void *restrict TO, const void *restrict
+- FROM, size_t SIZE)
+- The `memcpy' function copies SIZE bytes from the object beginning
+- at FROM into the object beginning at TO. The behavior of this
+- function is undefined if the two arrays TO and FROM overlap; use
+- `memmove' instead if overlapping is possible.
+-
+- The value returned by `memcpy' is the value of TO.
+-
+- Here is an example of how you might use `memcpy' to copy the
+- contents of an array:
+-
+- struct foo *oldarray, *newarray;
+- int arraysize;
+- ...
+- memcpy (new, old, arraysize * sizeof (struct foo));
+-
+- - Function: wchar_t * wmemcpy (wchar_t *restrict WTO, const wchar_t
+- *restruct WFROM, size_t SIZE)
+- The `wmemcpy' function copies SIZE wide characters from the object
+- beginning at WFROM into the object beginning at WTO. The behavior
+- of this function is undefined if the two arrays WTO and WFROM
+- overlap; use `wmemmove' instead if overlapping is possible.
+-
+- The following is a possible implementation of `wmemcpy' but there
+- are more optimizations possible.
+-
+- wchar_t *
+- wmemcpy (wchar_t *restrict wto, const wchar_t *restrict wfrom,
+- size_t size)
+- {
+- return (wchar_t *) memcpy (wto, wfrom, size * sizeof (wchar_t));
+- }
+-
+- The value returned by `wmemcpy' is the value of WTO.
+-
+- This function was introduced in Amendment 1 to ISO C90.
+-
+- - Function: void * mempcpy (void *restrict TO, const void *restrict
+- FROM, size_t SIZE)
+- The `mempcpy' function is nearly identical to the `memcpy'
+- function. It copies SIZE bytes from the object beginning at
+- `from' into the object pointed to by TO. But instead of returning
+- the value of TO it returns a pointer to the byte following the
+- last written byte in the object beginning at TO. I.e., the value
+- is `((void *) ((char *) TO + SIZE))'.
+-
+- This function is useful in situations where a number of objects
+- shall be copied to consecutive memory positions.
+-
+- void *
+- combine (void *o1, size_t s1, void *o2, size_t s2)
+- {
+- void *result = malloc (s1 + s2);
+- if (result != NULL)
+- mempcpy (mempcpy (result, o1, s1), o2, s2);
+- return result;
+- }
+-
+- This function is a GNU extension.
+-
+- - Function: wchar_t * wmempcpy (wchar_t *restrict WTO, const wchar_t
+- *restrict WFROM, size_t SIZE)
+- The `wmempcpy' function is nearly identical to the `wmemcpy'
+- function. It copies SIZE wide characters from the object
+- beginning at `wfrom' into the object pointed to by WTO. But
+- instead of returning the value of WTO it returns a pointer to the
+- wide character following the last written wide character in the
+- object beginning at WTO. I.e., the value is `WTO + SIZE'.
+-
+- This function is useful in situations where a number of objects
+- shall be copied to consecutive memory positions.
+-
+- The following is a possible implementation of `wmemcpy' but there
+- are more optimizations possible.
+-
+- wchar_t *
+- wmempcpy (wchar_t *restrict wto, const wchar_t *restrict wfrom,
+- size_t size)
+- {
+- return (wchar_t *) mempcpy (wto, wfrom, size * sizeof (wchar_t));
+- }
+-
+- This function is a GNU extension.
+-
+- - Function: void * memmove (void *TO, const void *FROM, size_t SIZE)
+- `memmove' copies the SIZE bytes at FROM into the SIZE bytes at TO,
+- even if those two blocks of space overlap. In the case of
+- overlap, `memmove' is careful to copy the original values of the
+- bytes in the block at FROM, including those bytes which also
+- belong to the block at TO.
+-
+- The value returned by `memmove' is the value of TO.
+-
+- - Function: wchar_t * wmemmove (wchar *WTO, const wchar_t *WFROM,
+- size_t SIZE)
+- `wmemmove' copies the SIZE wide characters at WFROM into the SIZE
+- wide characters at WTO, even if those two blocks of space overlap.
+- In the case of overlap, `memmove' is careful to copy the original
+- values of the wide characters in the block at WFROM, including
+- those wide characters which also belong to the block at WTO.
+-
+- The following is a possible implementation of `wmemcpy' but there
+- are more optimizations possible.
+-
+- wchar_t *
+- wmempcpy (wchar_t *restrict wto, const wchar_t *restrict wfrom,
+- size_t size)
+- {
+- return (wchar_t *) mempcpy (wto, wfrom, size * sizeof (wchar_t));
+- }
+-
+- The value returned by `wmemmove' is the value of WTO.
+-
+- This function is a GNU extension.
+-
+- - Function: void * memccpy (void *restrict TO, const void *restrict
+- FROM, int C, size_t SIZE)
+- This function copies no more than SIZE bytes from FROM to TO,
+- stopping if a byte matching C is found. The return value is a
+- pointer into TO one byte past where C was copied, or a null
+- pointer if no byte matching C appeared in the first SIZE bytes of
+- FROM.
+-
+- - Function: void * memset (void *BLOCK, int C, size_t SIZE)
+- This function copies the value of C (converted to an `unsigned
+- char') into each of the first SIZE bytes of the object beginning
+- at BLOCK. It returns the value of BLOCK.
+-
+- - Function: wchar_t * wmemset (wchar_t *BLOCK, wchar_t WC, size_t SIZE)
+- This function copies the value of WC into each of the first SIZE
+- wide characters of the object beginning at BLOCK. It returns the
+- value of BLOCK.
+-
+- - Function: char * strcpy (char *restrict TO, const char *restrict
+- FROM)
+- This copies characters from the string FROM (up to and including
+- the terminating null character) into the string TO. Like
+- `memcpy', this function has undefined results if the strings
+- overlap. The return value is the value of TO.
+-
+- - Function: wchar_t * wcscpy (wchar_t *restrict WTO, const wchar_t
+- *restrict WFROM)
+- This copies wide characters from the string WFROM (up to and
+- including the terminating null wide character) into the string
+- WTO. Like `wmemcpy', this function has undefined results if the
+- strings overlap. The return value is the value of WTO.
+-
+- - Function: char * strncpy (char *restrict TO, const char *restrict
+- FROM, size_t SIZE)
+- This function is similar to `strcpy' but always copies exactly
+- SIZE characters into TO.
+-
+- If the length of FROM is more than SIZE, then `strncpy' copies
+- just the first SIZE characters. Note that in this case there is
+- no null terminator written into TO.
+-
+- If the length of FROM is less than SIZE, then `strncpy' copies all
+- of FROM, followed by enough null characters to add up to SIZE
+- characters in all. This behavior is rarely useful, but it is
+- specified by the ISO C standard.
+-
+- The behavior of `strncpy' is undefined if the strings overlap.
+-
+- Using `strncpy' as opposed to `strcpy' is a way to avoid bugs
+- relating to writing past the end of the allocated space for TO.
+- However, it can also make your program much slower in one common
+- case: copying a string which is probably small into a potentially
+- large buffer. In this case, SIZE may be large, and when it is,
+- `strncpy' will waste a considerable amount of time copying null
+- characters.
+-
+- - Function: wchar_t * wcsncpy (wchar_t *restrict WTO, const wchar_t
+- *restrict WFROM, size_t SIZE)
+- This function is similar to `wcscpy' but always copies exactly
+- SIZE wide characters into WTO.
+-
+- If the length of WFROM is more than SIZE, then `wcsncpy' copies
+- just the first SIZE wide characters. Note that in this case there
+- is no null terminator written into WTO.
+-
+- If the length of WFROM is less than SIZE, then `wcsncpy' copies
+- all of WFROM, followed by enough null wide characters to add up to
+- SIZE wide characters in all. This behavior is rarely useful, but
+- it is specified by the ISO C standard.
+-
+- The behavior of `wcsncpy' is undefined if the strings overlap.
+-
+- Using `wcsncpy' as opposed to `wcscpy' is a way to avoid bugs
+- relating to writing past the end of the allocated space for WTO.
+- However, it can also make your program much slower in one common
+- case: copying a string which is probably small into a potentially
+- large buffer. In this case, SIZE may be large, and when it is,
+- `wcsncpy' will waste a considerable amount of time copying null
+- wide characters.
+-
+- - Function: char * strdup (const char *S)
+- This function copies the null-terminated string S into a newly
+- allocated string. The string is allocated using `malloc'; see
+- *Note Unconstrained Allocation::. If `malloc' cannot allocate
+- space for the new string, `strdup' returns a null pointer.
+- Otherwise it returns a pointer to the new string.
+-
+- - Function: wchar_t * wcsdup (const wchar_t *WS)
+- This function copies the null-terminated wide character string WS
+- into a newly allocated string. The string is allocated using
+- `malloc'; see *Note Unconstrained Allocation::. If `malloc'
+- cannot allocate space for the new string, `wcsdup' returns a null
+- pointer. Otherwise it returns a pointer to the new wide character
+- string.
+-
+- This function is a GNU extension.
+-
+- - Function: char * strndup (const char *S, size_t SIZE)
+- This function is similar to `strdup' but always copies at most
+- SIZE characters into the newly allocated string.
+-
+- If the length of S is more than SIZE, then `strndup' copies just
+- the first SIZE characters and adds a closing null terminator.
+- Otherwise all characters are copied and the string is terminated.
+-
+- This function is different to `strncpy' in that it always
+- terminates the destination string.
+-
+- `strndup' is a GNU extension.
+-
+- - Function: char * stpcpy (char *restrict TO, const char *restrict
+- FROM)
+- This function is like `strcpy', except that it returns a pointer to
+- the end of the string TO (that is, the address of the terminating
+- null character `to + strlen (from)') rather than the beginning.
+-
+- For example, this program uses `stpcpy' to concatenate `foo' and
+- `bar' to produce `foobar', which it then prints.
+-
+- #include <string.h>
+- #include <stdio.h>
+-
+- int
+- main (void)
+- {
+- char buffer[10];
+- char *to = buffer;
+- to = stpcpy (to, "foo");
+- to = stpcpy (to, "bar");
+- puts (buffer);
+- return 0;
+- }
+-
+- This function is not part of the ISO or POSIX standards, and is not
+- customary on Unix systems, but we did not invent it either.
+- Perhaps it comes from MS-DOG.
+-
+- Its behavior is undefined if the strings overlap. The function is
+- declared in `string.h'.
+-
+- - Function: wchar_t * wcpcpy (wchar_t *restrict WTO, const wchar_t
+- *restrict WFROM)
+- This function is like `wcscpy', except that it returns a pointer to
+- the end of the string WTO (that is, the address of the terminating
+- null character `wto + strlen (wfrom)') rather than the beginning.
+-
+- This function is not part of ISO or POSIX but was found useful
+- while developing the GNU C Library itself.
+-
+- The behavior of `wcpcpy' is undefined if the strings overlap.
+-
+- `wcpcpy' is a GNU extension and is declared in `wchar.h'.
+-
+- - Function: char * stpncpy (char *restrict TO, const char *restrict
+- FROM, size_t SIZE)
+- This function is similar to `stpcpy' but copies always exactly
+- SIZE characters into TO.
+-
+- If the length of FROM is more then SIZE, then `stpncpy' copies
+- just the first SIZE characters and returns a pointer to the
+- character directly following the one which was copied last. Note
+- that in this case there is no null terminator written into TO.
+-
+- If the length of FROM is less than SIZE, then `stpncpy' copies all
+- of FROM, followed by enough null characters to add up to SIZE
+- characters in all. This behavior is rarely useful, but it is
+- implemented to be useful in contexts where this behavior of the
+- `strncpy' is used. `stpncpy' returns a pointer to the _first_
+- written null character.
+-
+- This function is not part of ISO or POSIX but was found useful
+- while developing the GNU C Library itself.
+-
+- Its behavior is undefined if the strings overlap. The function is
+- declared in `string.h'.
+-
+- - Function: wchar_t * wcpncpy (wchar_t *restrict WTO, const wchar_t
+- *restrict WFROM, size_t SIZE)
+- This function is similar to `wcpcpy' but copies always exactly
+- WSIZE characters into WTO.
+-
+- If the length of WFROM is more then SIZE, then `wcpncpy' copies
+- just the first SIZE wide characters and returns a pointer to the
+- wide character directly following the one which was copied last.
+- Note that in this case there is no null terminator written into
+- WTO.
+-
+- If the length of WFROM is less than SIZE, then `wcpncpy' copies
+- all of WFROM, followed by enough null characters to add up to SIZE
+- characters in all. This behavior is rarely useful, but it is
+- implemented to be useful in contexts where this behavior of the
+- `wcsncpy' is used. `wcpncpy' returns a pointer to the _first_
+- written null character.
+-
+- This function is not part of ISO or POSIX but was found useful
+- while developing the GNU C Library itself.
+-
+- Its behavior is undefined if the strings overlap.
+-
+- `wcpncpy' is a GNU extension and is declared in `wchar.h'.
+-
+- - Macro: char * strdupa (const char *S)
+- This macro is similar to `strdup' but allocates the new string
+- using `alloca' instead of `malloc' (*note Variable Size
+- Automatic::). This means of course the returned string has the
+- same limitations as any block of memory allocated using `alloca'.
+-
+- For obvious reasons `strdupa' is implemented only as a macro; you
+- cannot get the address of this function. Despite this limitation
+- it is a useful function. The following code shows a situation
+- where using `malloc' would be a lot more expensive.
+-
+- #include <paths.h>
+- #include <string.h>
+- #include <stdio.h>
+-
+- const char path[] = _PATH_STDPATH;
+-
+- int
+- main (void)
+- {
+- char *wr_path = strdupa (path);
+- char *cp = strtok (wr_path, ":");
+-
+- while (cp != NULL)
+- {
+- puts (cp);
+- cp = strtok (NULL, ":");
+- }
+- return 0;
+- }
+-
+- Please note that calling `strtok' using PATH directly is invalid.
+- It is also not allowed to call `strdupa' in the argument list of
+- `strtok' since `strdupa' uses `alloca' (*note Variable Size
+- Automatic::) can interfere with the parameter passing.
+-
+- This function is only available if GNU CC is used.
+-
+- - Macro: char * strndupa (const char *S, size_t SIZE)
+- This function is similar to `strndup' but like `strdupa' it
+- allocates the new string using `alloca' *note Variable Size
+- Automatic::. The same advantages and limitations of `strdupa' are
+- valid for `strndupa', too.
+-
+- This function is implemented only as a macro, just like `strdupa'.
+- Just as `strdupa' this macro also must not be used inside the
+- parameter list in a function call.
+-
+- `strndupa' is only available if GNU CC is used.
+-
+- - Function: char * strcat (char *restrict TO, const char *restrict
+- FROM)
+- The `strcat' function is similar to `strcpy', except that the
+- characters from FROM are concatenated or appended to the end of
+- TO, instead of overwriting it. That is, the first character from
+- FROM overwrites the null character marking the end of TO.
+-
+- An equivalent definition for `strcat' would be:
+-
+- char *
+- strcat (char *restrict to, const char *restrict from)
+- {
+- strcpy (to + strlen (to), from);
+- return to;
+- }
+-
+- This function has undefined results if the strings overlap.
+-
+- - Function: wchar_t * wcscat (wchar_t *restrict WTO, const wchar_t
+- *restrict WFROM)
+- The `wcscat' function is similar to `wcscpy', except that the
+- characters from WFROM are concatenated or appended to the end of
+- WTO, instead of overwriting it. That is, the first character from
+- WFROM overwrites the null character marking the end of WTO.
+-
+- An equivalent definition for `wcscat' would be:
+-
+- wchar_t *
+- wcscat (wchar_t *wto, const wchar_t *wfrom)
+- {
+- wcscpy (wto + wcslen (wto), wfrom);
+- return wto;
+- }
+-
+- This function has undefined results if the strings overlap.
+-
+- Programmers using the `strcat' or `wcscat' function (or the
+-following `strncat' or `wcsncar' functions for that matter) can easily
+-be recognized as lazy and reckless. In almost all situations the
+-lengths of the participating strings are known (it better should be
+-since how can one otherwise ensure the allocated size of the buffer is
+-sufficient?) Or at least, one could know them if one keeps track of the
+-results of the various function calls. But then it is very inefficient
+-to use `strcat'/`wcscat'. A lot of time is wasted finding the end of
+-the destination string so that the actual copying can start. This is a
+-common example:
+-
+- /* This function concatenates arbitrarily many strings. The last
+- parameter must be `NULL'. */
+- char *
+- concat (const char *str, ...)
+- {
+- va_list ap, ap2;
+- size_t total = 1;
+- const char *s;
+- char *result;
+-
+- va_start (ap, str);
+- /* Actually `va_copy', but this is the name more gcc versions
+- understand. */
+- __va_copy (ap2, ap);
+-
+- /* Determine how much space we need. */
+- for (s = str; s != NULL; s = va_arg (ap, const char *))
+- total += strlen (s);
+-
+- va_end (ap);
+-
+- result = (char *) malloc (total);
+- if (result != NULL)
+- {
+- result[0] = '\0';
+-
+- /* Copy the strings. */
+- for (s = str; s != NULL; s = va_arg (ap2, const char *))
+- strcat (result, s);
+- }
+-
+- va_end (ap2);
+-
+- return result;
+- }
+-
+- This looks quite simple, especially the second loop where the strings
+-are actually copied. But these innocent lines hide a major performance
+-penalty. Just imagine that ten strings of 100 bytes each have to be
+-concatenated. For the second string we search the already stored 100
+-bytes for the end of the string so that we can append the next string.
+-For all strings in total the comparisons necessary to find the end of
+-the intermediate results sums up to 5500! If we combine the copying
+-with the search for the allocation we can write this function more
+-efficient:
+-
+- char *
+- concat (const char *str, ...)
+- {
+- va_list ap;
+- size_t allocated = 100;
+- char *result = (char *) malloc (allocated);
+- char *wp;
+-
+- if (allocated != NULL)
+- {
+- char *newp;
+-
+- va_start (ap, atr);
+-
+- wp = result;
+- for (s = str; s != NULL; s = va_arg (ap, const char *))
+- {
+- size_t len = strlen (s);
+-
+- /* Resize the allocated memory if necessary. */
+- if (wp + len + 1 > result + allocated)
+- {
+- allocated = (allocated + len) * 2;
+- newp = (char *) realloc (result, allocated);
+- if (newp == NULL)
+- {
+- free (result);
+- return NULL;
+- }
+- wp = newp + (wp - result);
+- result = newp;
+- }
+-
+- wp = mempcpy (wp, s, len);
+- }
+-
+- /* Terminate the result string. */
+- *wp++ = '\0';
+-
+- /* Resize memory to the optimal size. */
+- newp = realloc (result, wp - result);
+- if (newp != NULL)
+- result = newp;
+-
+- va_end (ap);
+- }
+-
+- return result;
+- }
+-
+- With a bit more knowledge about the input strings one could fine-tune
+-the memory allocation. The difference we are pointing to here is that
+-we don't use `strcat' anymore. We always keep track of the length of
+-the current intermediate result so we can safe us the search for the
+-end of the string and use `mempcpy'. Please note that we also don't
+-use `stpcpy' which might seem more natural since we handle with
+-strings. But this is not necessary since we already know the length of
+-the string and therefore can use the faster memory copying function.
+-The example would work for wide characters the same way.
+-
+- Whenever a programmer feels the need to use `strcat' she or he
+-should think twice and look through the program whether the code cannot
+-be rewritten to take advantage of already calculated results. Again: it
+-is almost always unnecessary to use `strcat'.
+-
+- - Function: char * strncat (char *restrict TO, const char *restrict
+- FROM, size_t SIZE)
+- This function is like `strcat' except that not more than SIZE
+- characters from FROM are appended to the end of TO. A single null
+- character is also always appended to TO, so the total allocated
+- size of TO must be at least `SIZE + 1' bytes longer than its
+- initial length.
+-
+- The `strncat' function could be implemented like this:
+-
+- char *
+- strncat (char *to, const char *from, size_t size)
+- {
+- to[strlen (to) + size] = '\0';
+- strncpy (to + strlen (to), from, size);
+- return to;
+- }
+-
+- The behavior of `strncat' is undefined if the strings overlap.
+-
+- - Function: wchar_t * wcsncat (wchar_t *restrict WTO, const wchar_t
+- *restrict WFROM, size_t SIZE)
+- This function is like `wcscat' except that not more than SIZE
+- characters from FROM are appended to the end of TO. A single null
+- character is also always appended to TO, so the total allocated
+- size of TO must be at least `SIZE + 1' bytes longer than its
+- initial length.
+-
+- The `wcsncat' function could be implemented like this:
+-
+- wchar_t *
+- wcsncat (wchar_t *restrict wto, const wchar_t *restrict wfrom,
+- size_t size)
+- {
+- wto[wcslen (to) + size] = L'\0';
+- wcsncpy (wto + wcslen (wto), wfrom, size);
+- return wto;
+- }
+-
+- The behavior of `wcsncat' is undefined if the strings overlap.
+-
+- Here is an example showing the use of `strncpy' and `strncat' (the
+-wide character version is equivalent). Notice how, in the call to
+-`strncat', the SIZE parameter is computed to avoid overflowing the
+-character array `buffer'.
+-
+- #include <string.h>
+- #include <stdio.h>
+-
+- #define SIZE 10
+-
+- static char buffer[SIZE];
+-
+- main ()
+- {
+- strncpy (buffer, "hello", SIZE);
+- puts (buffer);
+- strncat (buffer, ", world", SIZE - strlen (buffer) - 1);
+- puts (buffer);
+- }
+-
+-The output produced by this program looks like:
+-
+- hello
+- hello, wo
+-
+- - Function: void bcopy (const void *FROM, void *TO, size_t SIZE)
+- This is a partially obsolete alternative for `memmove', derived
+- from BSD. Note that it is not quite equivalent to `memmove',
+- because the arguments are not in the same order and there is no
+- return value.
+-
+- - Function: void bzero (void *BLOCK, size_t SIZE)
+- This is a partially obsolete alternative for `memset', derived from
+- BSD. Note that it is not as general as `memset', because the only
+- value it can store is zero.

+-String/Array Comparison
+-=======================
+-
+- You can use the functions in this section to perform comparisons on
+-the contents of strings and arrays. As well as checking for equality,
+-these functions can also be used as the ordering functions for sorting
+-operations. *Note Searching and Sorting::, for an example of this.
+-
+- Unlike most comparison operations in C, the string comparison
+-functions return a nonzero value if the strings are _not_ equivalent
+-rather than if they are. The sign of the value indicates the relative
+-ordering of the first characters in the strings that are not
+-equivalent: a negative value indicates that the first string is "less"
+-than the second, while a positive value indicates that the first string
+-is "greater".
+-
+- The most common use of these functions is to check only for equality.
+-This is canonically done with an expression like `! strcmp (s1, s2)'.
+-
+- All of these functions are declared in the header file `string.h'.
+-
+- - Function: int memcmp (const void *A1, const void *A2, size_t SIZE)
+- The function `memcmp' compares the SIZE bytes of memory beginning
+- at A1 against the SIZE bytes of memory beginning at A2. The value
+- returned has the same sign as the difference between the first
+- differing pair of bytes (interpreted as `unsigned char' objects,
+- then promoted to `int').
+-
+- If the contents of the two blocks are equal, `memcmp' returns `0'.
+-
+- - Function: int wmemcmp (const wchar_t *A1, const wchar_t *A2, size_t
+- SIZE)
+- The function `wmemcmp' compares the SIZE wide characters beginning
+- at A1 against the SIZE wide characters beginning at A2. The value
+- returned is smaller than or larger than zero depending on whether
+- the first differing wide character is A1 is smaller or larger than
+- the corresponding character in A2.
+-
+- If the contents of the two blocks are equal, `wmemcmp' returns `0'.
+-
+- On arbitrary arrays, the `memcmp' function is mostly useful for
+-testing equality. It usually isn't meaningful to do byte-wise ordering
+-comparisons on arrays of things other than bytes. For example, a
+-byte-wise comparison on the bytes that make up floating-point numbers
+-isn't likely to tell you anything about the relationship between the
+-values of the floating-point numbers.
+-
+- `wmemcmp' is really only useful to compare arrays of type `wchar_t'
+-since the function looks at `sizeof (wchar_t)' bytes at a time and this
+-number of bytes is system dependent.
+-
+- You should also be careful about using `memcmp' to compare objects
+-that can contain "holes", such as the padding inserted into structure
+-objects to enforce alignment requirements, extra space at the end of
+-unions, and extra characters at the ends of strings whose length is less
+-than their allocated size. The contents of these "holes" are
+-indeterminate and may cause strange behavior when performing byte-wise
+-comparisons. For more predictable results, perform an explicit
+-component-wise comparison.
+-
+- For example, given a structure type definition like:
+-
+- struct foo
+- {
+- unsigned char tag;
+- union
+- {
+- double f;
+- long i;
+- char *p;
+- } value;
+- };
+-
+-you are better off writing a specialized comparison function to compare
+-`struct foo' objects instead of comparing them with `memcmp'.
+-
+- - Function: int strcmp (const char *S1, const char *S2)
+- The `strcmp' function compares the string S1 against S2, returning
+- a value that has the same sign as the difference between the first
+- differing pair of characters (interpreted as `unsigned char'
+- objects, then promoted to `int').
+-
+- If the two strings are equal, `strcmp' returns `0'.
+-
+- A consequence of the ordering used by `strcmp' is that if S1 is an
+- initial substring of S2, then S1 is considered to be "less than"
+- S2.
+-
+- `strcmp' does not take sorting conventions of the language the
+- strings are written in into account. To get that one has to use
+- `strcoll'.
+-
+- - Function: int wcscmp (const wchar_t *WS1, const wchar_t *WS2)
+- The `wcscmp' function compares the wide character string WS1
+- against WS2. The value returned is smaller than or larger than
+- zero depending on whether the first differing wide character is
+- WS1 is smaller or larger than the corresponding character in WS2.
+-
+- If the two strings are equal, `wcscmp' returns `0'.
+-
+- A consequence of the ordering used by `wcscmp' is that if WS1 is
+- an initial substring of WS2, then WS1 is considered to be "less
+- than" WS2.
+-
+- `wcscmp' does not take sorting conventions of the language the
+- strings are written in into account. To get that one has to use
+- `wcscoll'.
+-
+- - Function: int strcasecmp (const char *S1, const char *S2)
+- This function is like `strcmp', except that differences in case are
+- ignored. How uppercase and lowercase characters are related is
+- determined by the currently selected locale. In the standard `"C"'
+- locale the characters A" and a" do not match but in a locale which
+- regards these characters as parts of the alphabet they do match.
+-
+- `strcasecmp' is derived from BSD.
+-
+- - Function: int wcscasecmp (const wchar_t *WS1, const wchar_T *WS2)
+- This function is like `wcscmp', except that differences in case are
+- ignored. How uppercase and lowercase characters are related is
+- determined by the currently selected locale. In the standard `"C"'
+- locale the characters A" and a" do not match but in a locale which
+- regards these characters as parts of the alphabet they do match.
+-
+- `wcscasecmp' is a GNU extension.
+-
+- - Function: int strncmp (const char *S1, const char *S2, size_t SIZE)
+- This function is the similar to `strcmp', except that no more than
+- SIZE wide characters are compared. In other words, if the two
+- strings are the same in their first SIZE wide characters, the
+- return value is zero.
+-
+- - Function: int wcsncmp (const wchar_t *WS1, const wchar_t *WS2,
+- size_t SIZE)
+- This function is the similar to `wcscmp', except that no more than
+- SIZE wide characters are compared. In other words, if the two
+- strings are the same in their first SIZE wide characters, the
+- return value is zero.
+-
+- - Function: int strncasecmp (const char *S1, const char *S2, size_t N)
+- This function is like `strncmp', except that differences in case
+- are ignored. Like `strcasecmp', it is locale dependent how
+- uppercase and lowercase characters are related.
+-
+- `strncasecmp' is a GNU extension.
+-
+- - Function: int wcsncasecmp (const wchar_t *WS1, const wchar_t *S2,
+- size_t N)
+- This function is like `wcsncmp', except that differences in case
+- are ignored. Like `wcscasecmp', it is locale dependent how
+- uppercase and lowercase characters are related.
+-
+- `wcsncasecmp' is a GNU extension.
+-
+- Here are some examples showing the use of `strcmp' and `strncmp'
+-(equivalent examples can be constructed for the wide character
+-functions). These examples assume the use of the ASCII character set.
+-(If some other character set--say, EBCDIC--is used instead, then the
+-glyphs are associated with different numeric codes, and the return
+-values and ordering may differ.)
+-
+- strcmp ("hello", "hello")
+- => 0 /* These two strings are the same. */
+- strcmp ("hello", "Hello")
+- => 32 /* Comparisons are case-sensitive. */
+- strcmp ("hello", "world")
+- => -15 /* The character `'h'' comes before `'w''. */
+- strcmp ("hello", "hello, world")
+- => -44 /* Comparing a null character against a comma. */
+- strncmp ("hello", "hello, world", 5)
+- => 0 /* The initial 5 characters are the same. */
+- strncmp ("hello, world", "hello, stupid world!!!", 5)
+- => 0 /* The initial 5 characters are the same. */
+-
+- - Function: int strverscmp (const char *S1, const char *S2)
+- The `strverscmp' function compares the string S1 against S2,
+- considering them as holding indices/version numbers. Return value
+- follows the same conventions as found in the `strverscmp'
+- function. In fact, if S1 and S2 contain no digits, `strverscmp'
+- behaves like `strcmp'.
+-
+- Basically, we compare strings normally (character by character),
+- until we find a digit in each string - then we enter a special
+- comparison mode, where each sequence of digits is taken as a
+- whole. If we reach the end of these two parts without noticing a
+- difference, we return to the standard comparison mode. There are
+- two types of numeric parts: "integral" and "fractional" (those
+- begin with a '0'). The types of the numeric parts affect the way
+- we sort them:
+-
+- * integral/integral: we compare values as you would expect.
+-
+- * fractional/integral: the fractional part is less than the
+- integral one. Again, no surprise.
+-
+- * fractional/fractional: the things become a bit more complex.
+- If the common prefix contains only leading zeroes, the
+- longest part is less than the other one; else the comparison
+- behaves normally.
+-
+- strverscmp ("no digit", "no digit")
+- => 0 /* same behavior as strcmp. */
+- strverscmp ("item#99", "item#100")
+- => <0 /* same prefix, but 99 < 100. */
+- strverscmp ("alpha1", "alpha001")
+- => >0 /* fractional part inferior to integral one. */
+- strverscmp ("part1_f012", "part1_f01")
+- => >0 /* two fractional parts. */
+- strverscmp ("foo.009", "foo.0")
+- => <0 /* idem, but with leading zeroes only. */
+-
+- This function is especially useful when dealing with filename
+- sorting, because filenames frequently hold indices/version numbers.
+-
+- `strverscmp' is a GNU extension.
+-
+- - Function: int bcmp (const void *A1, const void *A2, size_t SIZE)
+- This is an obsolete alias for `memcmp', derived from BSD.

+-
+-Collation Functions
+-===================
+-
+- In some locales, the conventions for lexicographic ordering differ
+-from the strict numeric ordering of character codes. For example, in
+-Spanish most glyphs with diacritical marks such as accents are not
+-considered distinct letters for the purposes of collation. On the
+-other hand, the two-character sequence `ll' is treated as a single
+-letter that is collated immediately after `l'.
+-
+- You can use the functions `strcoll' and `strxfrm' (declared in the
+-headers file `string.h') and `wcscoll' and `wcsxfrm' (declared in the
+-headers file `wchar') to compare strings using a collation ordering
+-appropriate for the current locale. The locale used by these functions
+-in particular can be specified by setting the locale for the
+-`LC_COLLATE' category; see *Note Locales::.
+-
+- In the standard C locale, the collation sequence for `strcoll' is
+-the same as that for `strcmp'. Similarly, `wcscoll' and `wcscmp' are
+-the same in this situation.
+-
+- Effectively, the way these functions work is by applying a mapping to
+-transform the characters in a string to a byte sequence that represents
+-the string's position in the collating sequence of the current locale.
+-Comparing two such byte sequences in a simple fashion is equivalent to
+-comparing the strings with the locale's collating sequence.
+-
+- The functions `strcoll' and `wcscoll' perform this translation
+-implicitly, in order to do one comparison. By contrast, `strxfrm' and
+-`wcsxfrm' perform the mapping explicitly. If you are making multiple
+-comparisons using the same string or set of strings, it is likely to be
+-more efficient to use `strxfrm' or `wcsxfrm' to transform all the
+-strings just once, and subsequently compare the transformed strings
+-with `strcmp' or `wcscmp'.
+-
+- - Function: int strcoll (const char *S1, const char *S2)
+- The `strcoll' function is similar to `strcmp' but uses the
+- collating sequence of the current locale for collation (the
+- `LC_COLLATE' locale).
+-
+- - Function: int wcscoll (const wchar_t *WS1, const wchar_t *WS2)
+- The `wcscoll' function is similar to `wcscmp' but uses the
+- collating sequence of the current locale for collation (the
+- `LC_COLLATE' locale).
+-
+- Here is an example of sorting an array of strings, using `strcoll'
+-to compare them. The actual sort algorithm is not written here; it
+-comes from `qsort' (*note Array Sort Function::). The job of the code
+-shown here is to say how to compare the strings while sorting them.
+-(Later on in this section, we will show a way to do this more
+-efficiently using `strxfrm'.)
+-
+- /* This is the comparison function used with `qsort'. */
+-
+- int
+- compare_elements (char **p1, char **p2)
+- {
+- return strcoll (*p1, *p2);
+- }
+-
+- /* This is the entry point--the function to sort
+- strings using the locale's collating sequence. */
+-
+- void
+- sort_strings (char **array, int nstrings)
+- {
+- /* Sort `temp_array' by comparing the strings. */
+- qsort (array, nstrings,
+- sizeof (char *), compare_elements);
+- }
+-
+- - Function: size_t strxfrm (char *restrict TO, const char *restrict
+- FROM, size_t SIZE)
+- The function `strxfrm' transforms the string FROM using the
+- collation transformation determined by the locale currently
+- selected for collation, and stores the transformed string in the
+- array TO. Up to SIZE characters (including a terminating null
+- character) are stored.
+-
+- The behavior is undefined if the strings TO and FROM overlap; see
+- *Note Copying and Concatenation::.
+-
+- The return value is the length of the entire transformed string.
+- This value is not affected by the value of SIZE, but if it is
+- greater or equal than SIZE, it means that the transformed string
+- did not entirely fit in the array TO. In this case, only as much
+- of the string as actually fits was stored. To get the whole
+- transformed string, call `strxfrm' again with a bigger output
+- array.
+-
+- The transformed string may be longer than the original string, and
+- it may also be shorter.
+-
+- If SIZE is zero, no characters are stored in TO. In this case,
+- `strxfrm' simply returns the number of characters that would be
+- the length of the transformed string. This is useful for
+- determining what size the allocated array should be. It does not
+- matter what TO is if SIZE is zero; TO may even be a null pointer.
+-
+- - Function: size_t wcsxfrm (wchar_t *restrict WTO, const wchar_t
+- *WFROM, size_t SIZE)
+- The function `wcsxfrm' transforms wide character string WFROM
+- using the collation transformation determined by the locale
+- currently selected for collation, and stores the transformed
+- string in the array WTO. Up to SIZE wide characters (including a
+- terminating null character) are stored.
+-
+- The behavior is undefined if the strings WTO and WFROM overlap;
+- see *Note Copying and Concatenation::.
+-
+- The return value is the length of the entire transformed wide
+- character string. This value is not affected by the value of
+- SIZE, but if it is greater or equal than SIZE, it means that the
+- transformed wide character string did not entirely fit in the
+- array WTO. In this case, only as much of the wide character
+- string as actually fits was stored. To get the whole transformed
+- wide character string, call `wcsxfrm' again with a bigger output
+- array.
+-
+- The transformed wide character string may be longer than the
+- original wide character string, and it may also be shorter.
+-
+- If SIZE is zero, no characters are stored in TO. In this case,
+- `wcsxfrm' simply returns the number of wide characters that would
+- be the length of the transformed wide character string. This is
+- useful for determining what size the allocated array should be
+- (remember to multiply with `sizeof (wchar_t)'). It does not
+- matter what WTO is if SIZE is zero; WTO may even be a null pointer.
+-
+- Here is an example of how you can use `strxfrm' when you plan to do
+-many comparisons. It does the same thing as the previous example, but
+-much faster, because it has to transform each string only once, no
+-matter how many times it is compared with other strings. Even the time
+-needed to allocate and free storage is much less than the time we save,
+-when there are many strings.

+- transformed = (char *) xmalloc (length);

+- /* Transform `array[i]'. */
+- transformed_length = strxfrm (transformed, array[i], length);

+- /* If the buffer was not large enough, resize it
+- and try again. */
+- if (transformed_length >= length)
+- {
+- /* Allocate the needed space. +1 for terminating
+- `NUL' character. */
+- transformed = (char *) xrealloc (transformed,
+- transformed_length + 1);
+-
+- /* The return value is not interesting because we know
+- how long the transformed string is. */
+- (void) strxfrm (transformed, array[i],
+- transformed_length + 1);
+- }
+-
+- temp_array[i].transformed = transformed;
+- }
+-
+- /* Sort `temp_array' by comparing transformed strings. */
+- qsort (temp_array, sizeof (struct sorter),

+- /* Put the elements back in the permanent array
+- in their sorted order. */
+- for (i = 0; i < nstrings; i++)
+- array[i] = temp_array[i].input;
+-
+- /* Free the strings we allocated. */
+- for (i = 0; i < nstrings; i++)
+- free (temp_array[i].transformed);
+- }
+-
+- The interesting part of this code for the wide character version
+-would look like this:
+-
+- void
+- sort_strings_fast (wchar_t **array, int nstrings)
+- {
+- ...
+- /* Transform `array[i]'. */
+- transformed_length = wcsxfrm (transformed, array[i], length);
+-
+- /* If the buffer was not large enough, resize it
+- and try again. */
+- if (transformed_length >= length)
+- {
+- /* Allocate the needed space. +1 for terminating
+- `NUL' character. */
+- transformed = (wchar_t *) xrealloc (transformed,
+- (transformed_length + 1)
+- * sizeof (wchar_t));
+-
+- /* The return value is not interesting because we know
+- how long the transformed string is. */
+- (void) wcsxfrm (transformed, array[i],
+- transformed_length + 1);
+- }
+- ...
+-
+-Note the additional multiplication with `sizeof (wchar_t)' in the
+-`realloc' call.
+-
+- *Compatibility Note:* The string collation functions are a new
+-feature of ISO C90. Older C dialects have no equivalent feature. The
+-wide character versions were introduced in Amendment 1 to ISO C90.

+-Search Functions
+-================
+-
+- This section describes library functions which perform various kinds
+-of searching operations on strings and arrays. These functions are
+-declared in the header file `string.h'.
+-
+- - Function: void * memchr (const void *BLOCK, int C, size_t SIZE)
+- This function finds the first occurrence of the byte C (converted
+- to an `unsigned char') in the initial SIZE bytes of the object
+- beginning at BLOCK. The return value is a pointer to the located
+- byte, or a null pointer if no match was found.
+-
+- - Function: wchar_t * wmemchr (const wchar_t *BLOCK, wchar_t WC,
+- size_t SIZE)
+- This function finds the first occurrence of the wide character WC
+- in the initial SIZE wide characters of the object beginning at
+- BLOCK. The return value is a pointer to the located wide
+- character, or a null pointer if no match was found.
+-
+- - Function: void * rawmemchr (const void *BLOCK, int C)
+- Often the `memchr' function is used with the knowledge that the
+- byte C is available in the memory block specified by the
+- parameters. But this means that the SIZE parameter is not really
+- needed and that the tests performed with it at runtime (to check
+- whether the end of the block is reached) are not needed.
+-
+- The `rawmemchr' function exists for just this situation which is
+- surprisingly frequent. The interface is similar to `memchr' except
+- that the SIZE parameter is missing. The function will look beyond
+- the end of the block pointed to by BLOCK in case the programmer
+- made an error in assuming that the byte C is present in the block.
+- In this case the result is unspecified. Otherwise the return
+- value is a pointer to the located byte.
+-
+- This function is of special interest when looking for the end of a
+- string. Since all strings are terminated by a null byte a call
+- like
+-
+- rawmemchr (str, '\0')
+-
+- will never go beyond the end of the string.
+-
+- This function is a GNU extension.
+-
+- - Function: void * memrchr (const void *BLOCK, int C, size_t SIZE)
+- The function `memrchr' is like `memchr', except that it searches
+- backwards from the end of the block defined by BLOCK and SIZE
+- (instead of forwards from the front).
+-
+- - Function: char * strchr (const char *STRING, int C)
+- The `strchr' function finds the first occurrence of the character
+- C (converted to a `char') in the null-terminated string beginning
+- at STRING. The return value is a pointer to the located
+- character, or a null pointer if no match was found.
+-
+- For example,
+- strchr ("hello, world", 'l')
+- => "llo, world"
+- strchr ("hello, world", '?')
+- => NULL
+-
+- The terminating null character is considered to be part of the
+- string, so you can use this function get a pointer to the end of a
+- string by specifying a null character as the value of the C
+- argument. It would be better (but less portable) to use
+- `strchrnul' in this case, though.
+-
+- - Function: wchar_t * wcschr (const wchar_t *WSTRING, int WC)
+- The `wcschr' function finds the first occurrence of the wide
+- character WC in the null-terminated wide character string
+- beginning at WSTRING. The return value is a pointer to the
+- located wide character, or a null pointer if no match was found.
+-
+- The terminating null character is considered to be part of the wide
+- character string, so you can use this function get a pointer to
+- the end of a wide character string by specifying a null wude
+- character as the value of the WC argument. It would be better
+- (but less portable) to use `wcschrnul' in this case, though.
+-
+- - Function: char * strchrnul (const char *STRING, int C)
+- `strchrnul' is the same as `strchr' except that if it does not
+- find the character, it returns a pointer to string's terminating
+- null character rather than a null pointer.
+-
+- This function is a GNU extension.
+-
+- - Function: wchar_t * wcschrnul (const wchar_t *WSTRING, wchar_t WC)
+- `wcschrnul' is the same as `wcschr' except that if it does not
+- find the wide character, it returns a pointer to wide character
+- string's terminating null wide character rather than a null
+- pointer.
+-
+- This function is a GNU extension.
+-
+- One useful, but unusual, use of the `strchr' function is when one
+-wants to have a pointer pointing to the NUL byte terminating a string.
+-This is often written in this way:
+-
+- s += strlen (s);
+-
+-This is almost optimal but the addition operation duplicated a bit of
+-the work already done in the `strlen' function. A better solution is
+-this:
+-
+- s = strchr (s, '\0');
+-
+- There is no restriction on the second parameter of `strchr' so it
+-could very well also be the NUL character. Those readers thinking very
+-hard about this might now point out that the `strchr' function is more
+-expensive than the `strlen' function since we have two abort criteria.
+-This is right. But in the GNU C library the implementation of `strchr'
+-is optimized in a special way so that `strchr' actually is faster.
+-
+- - Function: char * strrchr (const char *STRING, int C)
+- The function `strrchr' is like `strchr', except that it searches
+- backwards from the end of the string STRING (instead of forwards
+- from the front).
+-
+- For example,
+- strrchr ("hello, world", 'l')
+- => "ld"
+-
+- - Function: wchar_t * wcsrchr (const wchar_t *WSTRING, wchar_t C)
+- The function `wcsrchr' is like `wcschr', except that it searches
+- backwards from the end of the string WSTRING (instead of forwards
+- from the front).
+-
+- - Function: char * strstr (const char *HAYSTACK, const char *NEEDLE)
+- This is like `strchr', except that it searches HAYSTACK for a
+- substring NEEDLE rather than just a single character. It returns
+- a pointer into the string HAYSTACK that is the first character of
+- the substring, or a null pointer if no match was found. If NEEDLE
+- is an empty string, the function returns HAYSTACK.
+-
+- For example,
+- strstr ("hello, world", "l")
+- => "llo, world"
+- strstr ("hello, world", "wo")
+- => "world"
+-
+- - Function: wchar_t * wcsstr (const wchar_t *HAYSTACK, const wchar_t
+- *NEEDLE)
+- This is like `wcschr', except that it searches HAYSTACK for a
+- substring NEEDLE rather than just a single wide character. It
+- returns a pointer into the string HAYSTACK that is the first wide
+- character of the substring, or a null pointer if no match was
+- found. If NEEDLE is an empty string, the function returns
+- HAYSTACK.
+-
+- - Function: wchar_t * wcswcs (const wchar_t *HAYSTACK, const wchar_t
+- *NEEDLE)
+- `wcsstr' is an depricated alias for `wcsstr'. This is the name
+- originally used in the X/Open Portability Guide before the
+- Amendment 1 to ISO C90 was published.
+-
+- - Function: char * strcasestr (const char *HAYSTACK, const char
+- *NEEDLE)
+- This is like `strstr', except that it ignores case in searching for
+- the substring. Like `strcasecmp', it is locale dependent how
+- uppercase and lowercase characters are related.
+-
+- For example,
+- strstr ("hello, world", "L")
+- => "llo, world"
+- strstr ("hello, World", "wo")
+- => "World"
+-
+- - Function: void * memmem (const void *HAYSTACK, size_t HAYSTACK-LEN,
+- const void *NEEDLE, size_t NEEDLE-LEN)
+- This is like `strstr', but NEEDLE and HAYSTACK are byte arrays
+- rather than null-terminated strings. NEEDLE-LEN is the length of
+- NEEDLE and HAYSTACK-LEN is the length of HAYSTACK.
+-
+- This function is a GNU extension.
+-
+- - Function: size_t strspn (const char *STRING, const char *SKIPSET)
+- The `strspn' ("string span") function returns the length of the
+- initial substring of STRING that consists entirely of characters
+- that are members of the set specified by the string SKIPSET. The
+- order of the characters in SKIPSET is not important.
+-
+- For example,
+- strspn ("hello, world", "abcdefghijklmnopqrstuvwxyz")
+- => 5
+-
+- Note that "character" is here used in the sense of byte. In a
+- string using a multibyte character encoding (abstract) character
+- consisting of more than one byte are not treated as an entity.
+- Each byte is treated separately. The function is not
+- locale-dependent.
+-
+- - Function: size_t wcsspn (const wchar_t *WSTRING, const wchar_t
+- *SKIPSET)
+- The `wcsspn' ("wide character string span") function returns the
+- length of the initial substring of WSTRING that consists entirely
+- of wide characters that are members of the set specified by the
+- string SKIPSET. The order of the wide characters in SKIPSET is not
+- important.
+-
+- - Function: size_t strcspn (const char *STRING, const char *STOPSET)
+- The `strcspn' ("string complement span") function returns the
+- length of the initial substring of STRING that consists entirely
+- of characters that are _not_ members of the set specified by the
+- string STOPSET. (In other words, it returns the offset of the
+- first character in STRING that is a member of the set STOPSET.)
+-
+- For example,
+- strcspn ("hello, world", " \t\n,.;!?")
+- => 5
+-
+- Note that "character" is here used in the sense of byte. In a
+- string using a multibyte character encoding (abstract) character
+- consisting of more than one byte are not treated as an entity.
+- Each byte is treated separately. The function is not
+- locale-dependent.
+-
+- - Function: size_t wcscspn (const wchar_t *WSTRING, const wchar_t
+- *STOPSET)
+- The `wcscspn' ("wide character string complement span") function
+- returns the length of the initial substring of WSTRING that
+- consists entirely of wide characters that are _not_ members of the
+- set specified by the string STOPSET. (In other words, it returns
+- the offset of the first character in STRING that is a member of
+- the set STOPSET.)
+-
+- - Function: char * strpbrk (const char *STRING, const char *STOPSET)
+- The `strpbrk' ("string pointer break") function is related to
+- `strcspn', except that it returns a pointer to the first character
+- in STRING that is a member of the set STOPSET instead of the
+- length of the initial substring. It returns a null pointer if no
+- such character from STOPSET is found.
+-
+- For example,
+-
+- strpbrk ("hello, world", " \t\n,.;!?")
+- => ", world"
+-
+- Note that "character" is here used in the sense of byte. In a
+- string using a multibyte character encoding (abstract) character
+- consisting of more than one byte are not treated as an entity.
+- Each byte is treated separately. The function is not
+- locale-dependent.
+-
+- - Function: wchar_t * wcspbrk (const wchar_t *WSTRING, const wchar_t
+- *STOPSET)
+- The `wcspbrk' ("wide character string pointer break") function is
+- related to `wcscspn', except that it returns a pointer to the first
+- wide character in WSTRING that is a member of the set STOPSET
+- instead of the length of the initial substring. It returns a null
+- pointer if no such character from STOPSET is found.

+-
+-Finding Tokens in a String
+-==========================
+-
+- It's fairly common for programs to have a need to do some simple
+-kinds of lexical analysis and parsing, such as splitting a command
+-string up into tokens. You can do this with the `strtok' function,
+-declared in the header file `string.h'.
+-
+- - Function: char * strtok (char *restrict NEWSTRING, const char
+- *restrict DELIMITERS)
+- A string can be split into tokens by making a series of calls to
+- the function `strtok'.
+-
+- The string to be split up is passed as the NEWSTRING argument on
+- the first call only. The `strtok' function uses this to set up
+- some internal state information. Subsequent calls to get
+- additional tokens from the same string are indicated by passing a
+- null pointer as the NEWSTRING argument. Calling `strtok' with
+- another non-null NEWSTRING argument reinitializes the state
+- information. It is guaranteed that no other library function ever
+- calls `strtok' behind your back (which would mess up this internal
+- state information).
+-
+- The DELIMITERS argument is a string that specifies a set of
+- delimiters that may surround the token being extracted. All the
+- initial characters that are members of this set are discarded.
+- The first character that is _not_ a member of this set of
+- delimiters marks the beginning of the next token. The end of the
+- token is found by looking for the next character that is a member
+- of the delimiter set. This character in the original string
+- NEWSTRING is overwritten by a null character, and the pointer to
+- the beginning of the token in NEWSTRING is returned.
+-
+- On the next call to `strtok', the searching begins at the next
+- character beyond the one that marked the end of the previous token.
+- Note that the set of delimiters DELIMITERS do not have to be the
+- same on every call in a series of calls to `strtok'.
+-
+- If the end of the string NEWSTRING is reached, or if the remainder
+- of string consists only of delimiter characters, `strtok' returns
+- a null pointer.
+-
+- Note that "character" is here used in the sense of byte. In a
+- string using a multibyte character encoding (abstract) character
+- consisting of more than one byte are not treated as an entity.
+- Each byte is treated separately. The function is not
+- locale-dependent.

+- string using a multibyte character encoding (abstract) character

+- Each byte is treated separately. The function is not
+- locale-dependent.
+-
+- - Function: wchar_t * wcstok (wchar_t *NEWSTRING, const char
+- *DELIMITERS)
+- A string can be split into tokens by making a series of calls to
+- the function `wcstok'.
+-
+- The string to be split up is passed as the NEWSTRING argument on
+- the first call only. The `wcstok' function uses this to set up
+- some internal state information. Subsequent calls to get
+- additional tokens from the same wide character string are
+- indicated by passing a null pointer as the NEWSTRING argument.
+- Calling `wcstok' with another non-null NEWSTRING argument
+- reinitializes the state information. It is guaranteed that no
+- other library function ever calls `wcstok' behind your back (which
+- would mess up this internal state information).
+-
+- The DELIMITERS argument is a wide character string that specifies
+- a set of delimiters that may surround the token being extracted.
+- All the initial wide characters that are members of this set are
+- discarded. The first wide character that is _not_ a member of
+- this set of delimiters marks the beginning of the next token. The
+- end of the token is found by looking for the next wide character
+- that is a member of the delimiter set. This wide character in the
+- original wide character string NEWSTRING is overwritten by a null
+- wide character, and the pointer to the beginning of the token in
+- NEWSTRING is returned.
+-
+- On the next call to `wcstok', the searching begins at the next
+- wide character beyond the one that marked the end of the previous
+- token. Note that the set of delimiters DELIMITERS do not have to
+- be the same on every call in a series of calls to `wcstok'.
+-
+- If the end of the wide character string NEWSTRING is reached, or
+- if the remainder of string consists only of delimiter wide
+- characters, `wcstok' returns a null pointer.
+-
+- Note that "character" is here used in the sense of byte. In a
+- string using a multibyte character encoding (abstract) character
+- consisting of more than one byte are not treated as an entity.
+- Each byte is treated separately. The function is not
+- locale-dependent.
+-
+- *Warning:* Since `strtok' and `wcstok' alter the string they is
+-parsing, you should always copy the string to a temporary buffer before
+-parsing it with `strtok'/`wcstok' (*note Copying and Concatenation::).
+-If you allow `strtok' or `wcstok' to modify a string that came from
+-another part of your program, you are asking for trouble; that string
+-might be used for other purposes after `strtok' or `wcstok' has
+-modified it, and it would not have the expected value.
+-
+- The string that you are operating on might even be a constant. Then
+-when `strtok' or `wcstok' tries to modify it, your program will get a
+-fatal signal for writing in read-only memory. *Note Program Error
+-Signals::. Even if the operation of `strtok' or `wcstok' would not
+-require a modification of the string (e.g., if there is exactly one
+-token) the string can (and in the GNU libc case will) be modified.
+-
+- This is a special case of a general principle: if a part of a program
+-does not have as its purpose the modification of a certain data
+-structure, then it is error-prone to modify the data structure
+-temporarily.
+-
+- The functions `strtok' and `wcstok' are not reentrant. *Note
+-Nonreentrancy::, for a discussion of where and why reentrancy is
+-important.
+-
+- Here is a simple example showing the use of `strtok'.
+-
+- #include <string.h>
+- #include <stddef.h>
+-
+- ...
+-
+- const char string[] = "words separated by spaces -- and, punctuation!";
+- const char delimiters[] = " .,;:!-";
+- char *token, *cp;
+-
+- ...
+-
+- cp = strdupa (string); /* Make writable copy. */
+- token = strtok (cp, delimiters); /* token => "words" */
+- token = strtok (NULL, delimiters); /* token => "separated" */
+- token = strtok (NULL, delimiters); /* token => "by" */
+- token = strtok (NULL, delimiters); /* token => "spaces" */
+- token = strtok (NULL, delimiters); /* token => "and" */
+- token = strtok (NULL, delimiters); /* token => "punctuation" */
+- token = strtok (NULL, delimiters); /* token => NULL */
+-
+- The GNU C library contains two more functions for tokenizing a string
+-which overcome the limitation of non-reentrancy. They are only
+-available for multibyte character strings.
+-
+- - Function: char * strtok_r (char *NEWSTRING, const char *DELIMITERS,
+- char **SAVE_PTR)
+- Just like `strtok', this function splits the string into several
+- tokens which can be accessed by successive calls to `strtok_r'.
+- The difference is that the information about the next token is
+- stored in the space pointed to by the third argument, SAVE_PTR,
+- which is a pointer to a string pointer. Calling `strtok_r' with a
+- null pointer for NEWSTRING and leaving SAVE_PTR between the calls
+- unchanged does the job without hindering reentrancy.
+-
+- This function is defined in POSIX.1 and can be found on many
+- systems which support multi-threading.
+-
+- - Function: char * strsep (char **STRING_PTR, const char *DELIMITER)
+- This function has a similar functionality as `strtok_r' with the
+- NEWSTRING argument replaced by the SAVE_PTR argument. The
+- initialization of the moving pointer has to be done by the user.
+- Successive calls to `strsep' move the pointer along the tokens
+- separated by DELIMITER, returning the address of the next token
+- and updating STRING_PTR to point to the beginning of the next
+- token.
+-
+- One difference between `strsep' and `strtok_r' is that if the
+- input string contains more than one character from DELIMITER in a
+- row `strsep' returns an empty string for each pair of characters
+- from DELIMITER. This means that a program normally should test
+- for `strsep' returning an empty string before processing it.
+-
+- This function was introduced in 4.3BSD and therefore is widely
+- available.
+-
+- Here is how the above example looks like when `strsep' is used.
+-
+- #include <string.h>
+- #include <stddef.h>
+-
+- ...
+-
+- const char string[] = "words separated by spaces -- and, punctuation!";
+- const char delimiters[] = " .,;:!-";
+- char *running;
+- char *token;
+-
+- ...
+-
+- running = strdupa (string);
+- token = strsep (&running, delimiters); /* token => "words" */
+- token = strsep (&running, delimiters); /* token => "separated" */
+- token = strsep (&running, delimiters); /* token => "by" */
+- token = strsep (&running, delimiters); /* token => "spaces" */
+- token = strsep (&running, delimiters); /* token => "" */
+- token = strsep (&running, delimiters); /* token => "" */
+- token = strsep (&running, delimiters); /* token => "" */
+- token = strsep (&running, delimiters); /* token => "and" */
+- token = strsep (&running, delimiters); /* token => "" */
+- token = strsep (&running, delimiters); /* token => "punctuation" */
+- token = strsep (&running, delimiters); /* token => "" */
+- token = strsep (&running, delimiters); /* token => NULL */
+-
+- - Function: char * basename (const char *FILENAME)
+- The GNU version of the `basename' function returns the last
+- component of the path in FILENAME. This function is the preferred
+- usage, since it does not modify the argument, FILENAME, and
+- respects trailing slashes. The prototype for `basename' can be
+- found in `string.h'. Note, this function is overriden by the XPG
+- version, if `libgen.h' is included.
+-
+- Example of using GNU `basename':
+-
+- #include <string.h>
+-
+- int
+- main (int argc, char *argv[])
+- {
+- char *prog = basename (argv[0]);
+-
+- if (argc < 2)
+- {
+- fprintf (stderr, "Usage %s <arg>\n", prog);
+- exit (1);
+- }
+-
+- ...
+- }
+-
+- *Portability Note:* This function may produce different results on
+- different systems.
+-
+-
+- - Function: char * basename (char *PATH)
+- This is the standard XPG defined `basename'. It is similar in
+- spirit to the GNU version, but may modify the PATH by removing
+- trailing '/' characters. If the PATH is made up entirely of '/'
+- characters, then "/" will be returned. Also, if PATH is `NULL' or
+- an empty string, then "." is returned. The prototype for the XPG
+- version can be found in `libgen.h'.
+-
+- Example of using XPG `basename':
+-
+- #include <libgen.h>
+-
+- int
+- main (int argc, char *argv[])
+- {
+- char *prog;
+- char *path = strdupa (argv[0]);
+-
+- prog = basename (path);
+-
+- if (argc < 2)
+- {
+- fprintf (stderr, "Usage %s <arg>\n", prog);
+- exit (1);
+- }
+-
+- ...
+-
+- }
+-
+- - Function: char * dirname (char *PATH)
+- The `dirname' function is the compliment to the XPG version of
+- `basename'. It returns the parent directory of the file specified
+- by PATH. If PATH is `NULL', an empty string, or contains no '/'
+- characters, then "." is returned. The prototype for this function
+- can be found in `libgen.h'.

+-strfry
+-======
+-
+- The function below addresses the perennial programming quandary:
+-"How do I take good data in string form and painlessly turn it into
+-garbage?" This is actually a fairly simple task for C programmers who
+-do not use the GNU C library string functions, but for programs based
+-on the GNU C library, the `strfry' function is the preferred method for
+-destroying string data.
+-
+- The prototype for this function is in `string.h'.
+-
+- - Function: char * strfry (char *STRING)
+- `strfry' creates a pseudorandom anagram of a string, replacing the
+- input with the anagram in place. For each position in the string,
+- `strfry' swaps it with a position in the string selected at random
+- (from a uniform distribution). The two positions may be the same.
+-
+- The return value of `strfry' is always STRING.
+-
+- *Portability Note:* This function is unique to the GNU C library.

+-
+-Trivial Encryption
+-==================
+-
+- The `memfrob' function converts an array of data to something
+-unrecognizable and back again. It is not encryption in its usual sense
+-since it is easy for someone to convert the encrypted data back to clear
+-text. The transformation is analogous to Usenet's "Rot13" encryption
+-method for obscuring offensive jokes from sensitive eyes and such.
+-Unlike Rot13, `memfrob' works on arbitrary binary data, not just text.
+-
+- For true encryption, *Note Cryptographic Functions::.
+-
+- This function is declared in `string.h'.
+-
+- - Function: void * memfrob (void *MEM, size_t LENGTH)
+- `memfrob' transforms (frobnicates) each byte of the data structure
+- at MEM, which is LENGTH bytes long, by bitwise exclusive oring it
+- with binary 00101010. It does the transformation in place and its
+- return value is always MEM.
+-
+- Note that `memfrob' a second time on the same data structure
+- returns it to its original state.
+-
+- This is a good function for hiding information from someone who
+- doesn't want to see it or doesn't want to see it very much. To
+- really prevent people from retrieving the information, use
+- stronger encryption such as that described in *Note Cryptographic
+- Functions::.
+-
+- *Portability Note:* This function is unique to the GNU C library.

+-Encode Binary Data
+-==================
+-
+- To store or transfer binary data in environments which only support
+-text one has to encode the binary data by mapping the input bytes to
+-characters in the range allowed for storing or transfering. SVID
+-systems (and nowadays XPG compliant systems) provide minimal support for
+-this task.
+-
+- - Function: char * l64a (long int N)
+- This function encodes a 32-bit input value using characters from
+- the basic character set. It returns a pointer to a 6 character
+- buffer which contains an encoded version of N. To encode a series
+- of bytes the user must copy the returned string to a destination
+- buffer. It returns the empty string if N is zero, which is
+- somewhat bizarre but mandated by the standard.
+- *Warning:* Since a static buffer is used this function should not
+- be used in multi-threaded programs. There is no thread-safe
+- alternative to this function in the C library.
+- *Compatibility Note:* The XPG standard states that the return
+- value of `l64a' is undefined if N is negative. In the GNU
+- implementation, `l64a' treats its argument as unsigned, so it will
+- return a sensible encoding for any nonzero N; however, portable
+- programs should not rely on this.
+-
+- To encode a large buffer `l64a' must be called in a loop, once for
+- each 32-bit word of the buffer. For example, one could do
+- something like this:
+-
+- char *
+- encode (const void *buf, size_t len)
+- {
+- /* We know in advance how long the buffer has to be. */
+- unsigned char *in = (unsigned char *) buf;
+- char *out = malloc (6 + ((len + 3) / 4) * 6 + 1);
+- char *cp = out;
+-
+- /* Encode the length. */
+- /* Using `htonl' is necessary so that the data can be
+- decoded even on machines with different byte order. */
+-
+- cp = mempcpy (cp, l64a (htonl (len)), 6);
+-
+- while (len > 3)
+- {
+- unsigned long int n = *in++;
+- n = (n << 8) | *in++;
+- n = (n << 8) | *in++;
+- n = (n << 8) | *in++;
+- len -= 4;
+- if (n)
+- cp = mempcpy (cp, l64a (htonl (n)), 6);
+- else
+- /* `l64a' returns the empty string for n==0, so we
+- must generate its encoding ("......") by hand. */
+- cp = stpcpy (cp, "......");
+- }
+- if (len > 0)
+- {
+- unsigned long int n = *in++;
+- if (--len > 0)
+- {
+- n = (n << 8) | *in++;
+- if (--len > 0)
+- n = (n << 8) | *in;
+- }
+- memcpy (cp, l64a (htonl (n)), 6);
+- cp += 6;
+- }
+- *cp = '\0';
+- return out;
+- }
+-
+- It is strange that the library does not provide the complete
+- functionality needed but so be it.
+-
+-
+- To decode data produced with `l64a' the following function should be
+-used.
+-
+- - Function: long int a64l (const char *STRING)
+- The parameter STRING should contain a string which was produced by
+- a call to `l64a'. The function processes at least 6 characters of
+- this string, and decodes the characters it finds according to the
+- table below. It stops decoding when it finds a character not in
+- the table, rather like `atoi'; if you have a buffer which has been
+- broken into lines, you must be careful to skip over the
+- end-of-line characters.
+-
+- The decoded number is returned as a `long int' value.
+-
+- The `l64a' and `a64l' functions use a base 64 encoding, in which
+-each character of an encoded string represents six bits of an input
+-word. These symbols are used for the base 64 digits:
+-
+- 0 1 2 3 4 5 6 7
+-0 `.' `/' `0' `1' `2' `3' `4' `5'
+-8 `6' `7' `8' `9' `A' `B' `C' `D'
+-16 `E' `F' `G' `H' `I' `J' `K' `L'
+-24 `M' `N' `O' `P' `Q' `R' `S' `T'
+-32 `U' `V' `W' `X' `Y' `Z' `a' `b'
+-40 `c' `d' `e' `f' `g' `h' `i' `j'
+-48 `k' `l' `m' `n' `o' `p' `q' `r'
+-56 `s' `t' `u' `v' `w' `x' `y' `z'
+-
+- This encoding scheme is not standard. There are some other encoding
+-methods which are much more widely used (UU encoding, MIME encoding).
+-Generally, it is better to use one of these encodings.

+-Argz and Envz Vectors
+-=====================
+-
+- "argz vectors" are vectors of strings in a contiguous block of
+-memory, each element separated from its neighbors by null-characters
+-(`'\0'').
+-
+- "Envz vectors" are an extension of argz vectors where each element
+-is a name-value pair, separated by a `'='' character (as in a Unix
+-environment).

+-
+-Argz Functions
+---------------
+-
+- Each argz vector is represented by a pointer to the first element, of
+-type `char *', and a size, of type `size_t', both of which can be
+-initialized to `0' to represent an empty argz vector. All argz
+-functions accept either a pointer and a size argument, or pointers to
+-them, if they will be modified.
+-
+- The argz functions use `malloc'/`realloc' to allocate/grow argz
+-vectors, and so any argz vector creating using these functions may be
+-freed by using `free'; conversely, any argz function that may grow a
+-string expects that string to have been allocated using `malloc' (those
+-argz functions that only examine their arguments or modify them in
+-place will work on any sort of memory). *Note Unconstrained
+-Allocation::.
+-
+- All argz functions that do memory allocation have a return type of
+-`error_t', and return `0' for success, and `ENOMEM' if an allocation
+-error occurs.
+-
+- These functions are declared in the standard include file `argz.h'.
+-
+- - Function: error_t argz_create (char *const ARGV[], char **ARGZ,
+- size_t *ARGZ_LEN)
+- The `argz_create' function converts the Unix-style argument vector
+- ARGV (a vector of pointers to normal C strings, terminated by
+- `(char *)0'; *note Program Arguments::) into an argz vector with
+- the same elements, which is returned in ARGZ and ARGZ_LEN.
+-
+- - Function: error_t argz_create_sep (const char *STRING, int SEP, char
+- **ARGZ, size_t *ARGZ_LEN)
+- The `argz_create_sep' function converts the null-terminated string
+- STRING into an argz vector (returned in ARGZ and ARGZ_LEN) by
+- splitting it into elements at every occurrence of the character
+- SEP.
+-
+- - Function: size_t argz_count (const char *ARGZ, size_t ARG_LEN)
+- Returns the number of elements in the argz vector ARGZ and
+- ARGZ_LEN.
+-
+- - Function: void argz_extract (char *ARGZ, size_t ARGZ_LEN, char
+- **ARGV)
+- The `argz_extract' function converts the argz vector ARGZ and
+- ARGZ_LEN into a Unix-style argument vector stored in ARGV, by
+- putting pointers to every element in ARGZ into successive
+- positions in ARGV, followed by a terminator of `0'. ARGV must be
+- pre-allocated with enough space to hold all the elements in ARGZ
+- plus the terminating `(char *)0' (`(argz_count (ARGZ, ARGZ_LEN) +
+- 1) * sizeof (char *)' bytes should be enough). Note that the
+- string pointers stored into ARGV point into ARGZ--they are not
+- copies--and so ARGZ must be copied if it will be changed while
+- ARGV is still active. This function is useful for passing the
+- elements in ARGZ to an exec function (*note Executing a File::).
+-
+- - Function: void argz_stringify (char *ARGZ, size_t LEN, int SEP)
+- The `argz_stringify' converts ARGZ into a normal string with the
+- elements separated by the character SEP, by replacing each `'\0''
+- inside ARGZ (except the last one, which terminates the string)
+- with SEP. This is handy for printing ARGZ in a readable manner.
+-
+- - Function: error_t argz_add (char **ARGZ, size_t *ARGZ_LEN, const
+- char *STR)
+- The `argz_add' function adds the string STR to the end of the argz
+- vector `*ARGZ', and updates `*ARGZ' and `*ARGZ_LEN' accordingly.
+-
+- - Function: error_t argz_add_sep (char **ARGZ, size_t *ARGZ_LEN, const
+- char *STR, int DELIM)
+- The `argz_add_sep' function is similar to `argz_add', but STR is
+- split into separate elements in the result at occurrences of the
+- character DELIM. This is useful, for instance, for adding the
+- components of a Unix search path to an argz vector, by using a
+- value of `':'' for DELIM.
+-
+- - Function: error_t argz_append (char **ARGZ, size_t *ARGZ_LEN, const
+- char *BUF, size_t BUF_LEN)
+- The `argz_append' function appends BUF_LEN bytes starting at BUF
+- to the argz vector `*ARGZ', reallocating `*ARGZ' to accommodate
+- it, and adding BUF_LEN to `*ARGZ_LEN'.
+-
+- - Function: error_t argz_delete (char **ARGZ, size_t *ARGZ_LEN, char
+- *ENTRY)
+- If ENTRY points to the beginning of one of the elements in the
+- argz vector `*ARGZ', the `argz_delete' function will remove this
+- entry and reallocate `*ARGZ', modifying `*ARGZ' and `*ARGZ_LEN'
+- accordingly. Note that as destructive argz functions usually
+- reallocate their argz argument, pointers into argz vectors such as
+- ENTRY will then become invalid.
+-
+- - Function: error_t argz_insert (char **ARGZ, size_t *ARGZ_LEN, char
+- *BEFORE, const char *ENTRY)
+- The `argz_insert' function inserts the string ENTRY into the argz
+- vector `*ARGZ' at a point just before the existing element pointed
+- to by BEFORE, reallocating `*ARGZ' and updating `*ARGZ' and
+- `*ARGZ_LEN'. If BEFORE is `0', ENTRY is added to the end instead
+- (as if by `argz_add'). Since the first element is in fact the
+- same as `*ARGZ', passing in `*ARGZ' as the value of BEFORE will
+- result in ENTRY being inserted at the beginning.
+-
+- - Function: char * argz_next (char *ARGZ, size_t ARGZ_LEN, const char
+- *ENTRY)
+- The `argz_next' function provides a convenient way of iterating
+- over the elements in the argz vector ARGZ. It returns a pointer
+- to the next element in ARGZ after the element ENTRY, or `0' if
+- there are no elements following ENTRY. If ENTRY is `0', the first
+- element of ARGZ is returned.
+-
+- This behavior suggests two styles of iteration:
+-
+- char *entry = 0;
+- while ((entry = argz_next (ARGZ, ARGZ_LEN, entry)))
+- ACTION;
+-
+- (the double parentheses are necessary to make some C compilers
+- shut up about what they consider a questionable `while'-test) and:
+-
+- char *entry;
+- for (entry = ARGZ;
+- entry;
+- entry = argz_next (ARGZ, ARGZ_LEN, entry))
+- ACTION;
+-
+- Note that the latter depends on ARGZ having a value of `0' if it
+- is empty (rather than a pointer to an empty block of memory); this
+- invariant is maintained for argz vectors created by the functions
+- here.
+-
+- - Function: error_t argz_replace (char **ARGZ, size_t *ARGZ_LEN,
+- const char *STR, const char *WITH, unsigned *REPLACE_COUNT)
+- Replace any occurrences of the string STR in ARGZ with WITH,
+- reallocating ARGZ as necessary. If REPLACE_COUNT is non-zero,
+- `*REPLACE_COUNT' will be incremented by number of replacements
+- performed.

+-
+-Envz Functions
+---------------
+-
+- Envz vectors are just argz vectors with additional constraints on
+-the form of each element; as such, argz functions can also be used on
+-them, where it makes sense.
+-
+- Each element in an envz vector is a name-value pair, separated by a
+-`'='' character; if multiple `'='' characters are present in an
+-element, those after the first are considered part of the value, and
+-treated like all other non-`'\0'' characters.
+-
+- If _no_ `'='' characters are present in an element, that element is
+-considered the name of a "null" entry, as distinct from an entry with an
+-empty value: `envz_get' will return `0' if given the name of null
+-entry, whereas an entry with an empty value would result in a value of
+-`""'; `envz_entry' will still find such entries, however. Null entries
+-can be removed with `envz_strip' function.
+-
+- As with argz functions, envz functions that may allocate memory (and
+-thus fail) have a return type of `error_t', and return either `0' or
+-`ENOMEM'.
+-
+- These functions are declared in the standard include file `envz.h'.
+-
+- - Function: char * envz_entry (const char *ENVZ, size_t ENVZ_LEN,
+- const char *NAME)
+- The `envz_entry' function finds the entry in ENVZ with the name
+- NAME, and returns a pointer to the whole entry--that is, the argz
+- element which begins with NAME followed by a `'='' character. If
+- there is no entry with that name, `0' is returned.
+-
+- - Function: char * envz_get (const char *ENVZ, size_t ENVZ_LEN, const
+- char *NAME)
+- The `envz_get' function finds the entry in ENVZ with the name NAME
+- (like `envz_entry'), and returns a pointer to the value portion of
+- that entry (following the `'=''). If there is no entry with that
+- name (or only a null entry), `0' is returned.
+-
+- - Function: error_t envz_add (char **ENVZ, size_t *ENVZ_LEN, const
+- char *NAME, const char *VALUE)
+- The `envz_add' function adds an entry to `*ENVZ' (updating `*ENVZ'
+- and `*ENVZ_LEN') with the name NAME, and value VALUE. If an entry
+- with the same name already exists in ENVZ, it is removed first.
+- If VALUE is `0', then the new entry will the special null type of
+- entry (mentioned above).
+-
+- - Function: error_t envz_merge (char **ENVZ, size_t *ENVZ_LEN, const
+- char *ENVZ2, size_t ENVZ2_LEN, int OVERRIDE)
+- The `envz_merge' function adds each entry in ENVZ2 to ENVZ, as if
+- with `envz_add', updating `*ENVZ' and `*ENVZ_LEN'. If OVERRIDE is
+- true, then values in ENVZ2 will supersede those with the same name
+- in ENVZ, otherwise not.
+-
+- Null entries are treated just like other entries in this respect,
+- so a null entry in ENVZ can prevent an entry of the same name in
+- ENVZ2 from being added to ENVZ, if OVERRIDE is false.
+-
+- - Function: void envz_strip (char **ENVZ, size_t *ENVZ_LEN)
+- The `envz_strip' function removes any null entries from ENVZ,
+- updating `*ENVZ' and `*ENVZ_LEN'.

+-Introduction to Extended Characters
+-===================================
+-
+- A variety of solutions is available to overcome the differences
+-between character sets with a 1:1 relation between bytes and characters
+-and character sets with ratios of 2:1 or 4:1. The remainder of this
+-section gives a few examples to help understand the design decisions
+-made while developing the functionality of the C library.
+-
+- A distinction we have to make right away is between internal and
+-external representation. "Internal representation" means the
+-representation used by a program while keeping the text in memory.
+-External representations are used when text is stored or transmitted
+-through some communication channel. Examples of external
+-representations include files waiting in a directory to be read and
+-parsed.
+-
+- Traditionally there has been no difference between the two
+-representations. It was equally comfortable and useful to use the same
+-single-byte representation internally and externally. This comfort
+-level decreases with more and larger character sets.
+-
+- One of the problems to overcome with the internal representation is
+-handling text that is externally encoded using different character
+-sets. Assume a program that reads two texts and compares them using
+-some metric. The comparison can be usefully done only if the texts are
+-internally kept in a common format.
+-
+- For such a common format (= character set) eight bits are certainly
+-no longer enough. So the smallest entity will have to grow: "wide
+-characters" will now be used. Instead of one byte per character, two or
+-four will be used instead. (Three are not good to address in memory and
+-more than four bytes seem not to be necessary).
+-
+- As shown in some other part of this manual, a completely new family
+-has been created of functions that can handle wide character texts in
+-memory. The most commonly used character sets for such internal wide
+-character representations are Unicode and ISO 10646 (also known as UCS
+-for Universal Character Set). Unicode was originally planned as a
+-16-bit character set; whereas, ISO 10646 was designed to be a 31-bit
+-large code space. The two standards are practically identical. They
+-have the same character repertoire and code table, but Unicode specifies
+-added semantics. At the moment, only characters in the first `0x10000'
+-code positions (the so-called Basic Multilingual Plane, BMP) have been
+-assigned, but the assignment of more specialized characters outside this
+-16-bit space is already in progress. A number of encodings have been
+-defined for Unicode and ISO 10646 characters: UCS-2 is a 16-bit word
+-that can only represent characters from the BMP, UCS-4 is a 32-bit word
+-than can represent any Unicode and ISO 10646 character, UTF-8 is an
+-ASCII compatible encoding where ASCII characters are represented by
+-ASCII bytes and non-ASCII characters by sequences of 2-6 non-ASCII
+-bytes, and finally UTF-16 is an extension of UCS-2 in which pairs of
+-certain UCS-2 words can be used to encode non-BMP characters up to
+-`0x10ffff'.
+-
+- To represent wide characters the `char' type is not suitable. For
+-this reason the ISO C standard introduces a new type that is designed
+-to keep one character of a wide character string. To maintain the
+-similarity there is also a type corresponding to `int' for those
+-functions that take a single wide character.
+-
+- - Data type: wchar_t
+- This data type is used as the base type for wide character strings.
+- In other words, arrays of objects of this type are the equivalent
+- of `char[]' for multibyte character strings. The type is defined
+- in `stddef.h'.
+-
+- The ISO C90 standard, where `wchar_t' was introduced, does not say
+- anything specific about the representation. It only requires that
+- this type is capable of storing all elements of the basic
+- character set. Therefore it would be legitimate to define
+- `wchar_t' as `char', which might make sense for embedded systems.
+-
+- But for GNU systems `wchar_t' is always 32 bits wide and,
+- therefore, capable of representing all UCS-4 values and,
+- therefore, covering all of ISO 10646. Some Unix systems define
+- `wchar_t' as a 16-bit type and thereby follow Unicode very
+- strictly. This definition is perfectly fine with the standard,
+- but it also means that to represent all characters from Unicode
+- and ISO 10646 one has to use UTF-16 surrogate characters, which is
+- in fact a multi-wide-character encoding. But resorting to
+- multi-wide-character encoding contradicts the purpose of the
+- `wchar_t' type.
+-
+- - Data type: wint_t
+- `wint_t' is a data type used for parameters and variables that
+- contain a single wide character. As the name suggests this type
+- is the equivalent of `int' when using the normal `char' strings.
+- The types `wchar_t' and `wint_t' often have the same
+- representation if their size is 32 bits wide but if `wchar_t' is
+- defined as `char' the type `wint_t' must be defined as `int' due
+- to the parameter promotion.
+-
+- This type is defined in `wchar.h' and was introduced in
+- Amendment 1 to ISO C90.
+-
+- As there are for the `char' data type macros are available for
+-specifying the minimum and maximum value representable in an object of
+-type `wchar_t'.
+-
+- - Macro: wint_t WCHAR_MIN
+- The macro `WCHAR_MIN' evaluates to the minimum value representable
+- by an object of type `wint_t'.
+-
+- This macro was introduced in Amendment 1 to ISO C90.
+-
+- - Macro: wint_t WCHAR_MAX
+- The macro `WCHAR_MAX' evaluates to the maximum value representable
+- by an object of type `wint_t'.
+-
+- This macro was introduced in Amendment 1 to ISO C90.
+-
+- Another special wide character value is the equivalent to `EOF'.
+-
+- - Macro: wint_t WEOF
+- The macro `WEOF' evaluates to a constant expression of type
+- `wint_t' whose value is different from any member of the extended
+- character set.
+-
+- `WEOF' need not be the same value as `EOF' and unlike `EOF' it
+- also need _not_ be negative. In other words, sloppy code like
+-
+- {
+- int c;
+- ...
+- while ((c = getc (fp)) < 0)
+- ...
+- }
+-
+- has to be rewritten to use `WEOF' explicitly when wide characters
+- are used:
+-
+- {
+- wint_t c;
+- ...
+- while ((c = wgetc (fp)) != WEOF)
+- ...
+- }
+-
+- This macro was introduced in Amendment 1 to ISO C90 and is defined
+- in `wchar.h'.
+-
+- These internal representations present problems when it comes to
+-storing and transmittal. Because each single wide character consists
+-of more than one byte, they are effected by byte-ordering. Thus,
+-machines with different endianesses would see different values when
+-accessing the same data. This byte ordering concern also applies for
+-communication protocols that are all byte-based and, thereforet require
+-that the sender has to decide about splitting the wide character in
+-bytes. A last (but not least important) point is that wide characters
+-often require more storage space than a customized byte-oriented
+-character set.
+-
+- For all the above reasons, an external encoding that is different
+-from the internal encoding is often used if the latter is UCS-2 or
+-UCS-4. The external encoding is byte-based and can be chosen
+-appropriately for the environment and for the texts to be handled. A
+-variety of different character sets can be used for this external
+-encoding (information that will not be exhaustively presented
+-here-instead, a description of the major groups will suffice). All of
+-the ASCII-based character sets fulfill one requirement: they are
+-"filesystem safe." This means that the character `'/'' is used in the
+-encoding _only_ to represent itself. Things are a bit different for
+-character sets like EBCDIC (Extended Binary Coded Decimal Interchange
+-Code, a character set family used by IBM), but if the operation system
+-does not understand EBCDIC directly the parameters-to-system calls have
+-to be converted first anyhow.
+-
+- * The simplest character sets are single-byte character sets. There
+- can be only up to 256 characters (for 8 bit character sets), which
+- is not sufficient to cover all languages but might be sufficient
+- to handle a specific text. Handling of a 8 bit character sets is
+- simple. This is not true for other kinds presented later, and
+- therefore, the application one uses might require the use of 8 bit
+- character sets.
+-
+- * The ISO 2022 standard defines a mechanism for extended character
+- sets where one character _can_ be represented by more than one
+- byte. This is achieved by associating a state with the text.
+- Characters that can be used to change the state can be embedded in
+- the text. Each byte in the text might have a different
+- interpretation in each state. The state might even influence
+- whether a given byte stands for a character on its own or whether
+- it has to be combined with some more bytes.
+-
+- In most uses of ISO 2022 the defined character sets do not allow
+- state changes that cover more than the next character. This has
+- the big advantage that whenever one can identify the beginning of
+- the byte sequence of a character one can interpret a text
+- correctly. Examples of character sets using this policy are the
+- various EUC character sets (used by Sun's operations systems,
+- EUC-JP, EUC-KR, EUC-TW, and EUC-CN) or Shift_JIS (SJIS, a Japanese
+- encoding).
+-
+- But there are also character sets using a state that is valid for
+- more than one character and has to be changed by another byte
+- sequence. Examples for this are ISO-2022-JP, ISO-2022-KR, and
+- ISO-2022-CN.
+-
+- * Early attempts to fix 8 bit character sets for other languages
+- using the Roman alphabet lead to character sets like ISO 6937.
+- Here bytes representing characters like the acute accent do not
+- produce output themselves: one has to combine them with other
+- characters to get the desired result. For example, the byte
+- sequence `0xc2 0x61' (non-spacing acute accent, followed by
+- lower-case `a') to get the "small a with acute" character. To
+- get the acute accent character on its own, one has to write `0xc2
+- 0x20' (the non-spacing acute followed by a space).
+-
+- Character sets like ISO 6937 are used in some embedded systems such
+- as teletex.
+-
+- * Instead of converting the Unicode or ISO 10646 text used
+- internally, it is often also sufficient to simply use an encoding
+- different than UCS-2/UCS-4. The Unicode and ISO 10646 standards
+- even specify such an encoding: UTF-8. This encoding is able to
+- represent all of ISO 10646 31 bits in a byte string of length one
+- to six.
+-
+- There were a few other attempts to encode ISO 10646 such as UTF-7,
+- but UTF-8 is today the only encoding that should be used. In
+- fact, with any luck UTF-8 will soon be the only external encoding
+- that has to be supported. It proves to be universally usable and
+- its only disadvantage is that it favors Roman languages by making
+- the byte string representation of other scripts (Cyrillic, Greek,
+- Asian scripts) longer than necessary if using a specific character
+- set for these scripts. Methods like the Unicode compression
+- scheme can alleviate these problems.
+-
+- The question remaining is: how to select the character set or
+-encoding to use. The answer: you cannot decide about it yourself, it
+-is decided by the developers of the system or the majority of the
+-users. Since the goal is interoperability one has to use whatever the
+-other people one works with use. If there are no constraints, the
+-selection is based on the requirements the expected circle of users
+-will have. In other words, if a project is expected to be used in
+-only, say, Russia it is fine to use KOI8-R or a similar character set.
+-But if at the same time people from, say, Greece are participating one
+-should use a character set that allows all people to collaborate.
+-
+- The most widely useful solution seems to be: go with the most general
+-character set, namely ISO 10646. Use UTF-8 as the external encoding
+-and problems about users not being able to use their own language
+-adequately are a thing of the past.
+-
+- One final comment about the choice of the wide character
+-representation is necessary at this point. We have said above that the
+-natural choice is using Unicode or ISO 10646. This is not required,
+-but at least encouraged, by the ISO C standard. The standard defines
+-at least a macro `__STDC_ISO_10646__' that is only defined on systems
+-where the `wchar_t' type encodes ISO 10646 characters. If this symbol
+-is not defined one should avoid making assumptions about the wide
+-character representation. If the programmer uses only the functions
+-provided by the C library to handle wide character strings there should
+-be no compatibility problems with other systems.

+-Overview about Character Handling Functions
+-===========================================
+-
+- A Unix C library contains three different sets of functions in two
+-families to handle character set conversion. One of the function
+-families (the most commonly used) is specified in the ISO C90 standard
+-and, therefore, is portable even beyond the Unix world. Unfortunately
+-this family is the least useful one. These functions should be avoided
+-whenever possible, especially when developing libraries (as opposed to
+-applications).
+-
+- The second family of functions got introduced in the early Unix
+-standards (XPG2) and is still part of the latest and greatest Unix
+-standard: Unix 98. It is also the most powerful and useful set of
+-functions. But we will start with the functions defined in Amendment 1
+-to ISO C90.

+-
+-Restartable Multibyte Conversion Functions
+-==========================================
+-
+- The ISO C standard defines functions to convert strings from a
+-multibyte representation to wide character strings. There are a number
+-of peculiarities:
+-
+- * The character set assumed for the multibyte encoding is not
+- specified as an argument to the functions. Instead the character
+- set specified by the `LC_CTYPE' category of the current locale is
+- used; see *Note Locale Categories::.
+-
+- * The functions handling more than one character at a time require
+- NUL terminated strings as the argument (i.e., converting blocks of
+- text does not work unless one can add a NUL byte at an appropriate
+- place). The GNU C library contains some extensions to the
+- standard that allow specifying a size, but basically they also
+- expect terminated strings.
+-
+- Despite these limitations the ISO C functions can be used in many
+-contexts. In graphical user interfaces, for instance, it is not
+-uncommon to have functions that require text to be displayed in a wide
+-character string if the text is not simple ASCII. The text itself might
+-come from a file with translations and the user should decide about the
+-current locale, which determines the translation and therefore also the
+-external encoding used. In such a situation (and many others) the
+-functions described here are perfect. If more freedom while performing
+-the conversion is necessary take a look at the `iconv' functions (*note
+-Generic Charset Conversion::).

+-
+-Selecting the conversion and its properties
+--------------------------------------------
+-
+- We already said above that the currently selected locale for the
+-`LC_CTYPE' category decides about the conversion that is performed by
+-the functions we are about to describe. Each locale uses its own
+-character set (given as an argument to `localedef') and this is the one
+-assumed as the external multibyte encoding. The wide character
+-character set always is UCS-4, at least on GNU systems.
+-
+- A characteristic of each multibyte character set is the maximum
+-number of bytes that can be necessary to represent one character. This
+-information is quite important when writing code that uses the
+-conversion functions (as shown in the examples below). The ISO C
+-standard defines two macros that provide this information.
+-
+- - Macro: int MB_LEN_MAX
+- `MB_LEN_MAX' specifies the maximum number of bytes in the multibyte
+- sequence for a single character in any of the supported locales.
+- It is a compile-time constant and is defined in `limits.h'.
+-
+- - Macro: int MB_CUR_MAX
+- `MB_CUR_MAX' expands into a positive integer expression that is the
+- maximum number of bytes in a multibyte character in the current
+- locale. The value is never greater than `MB_LEN_MAX'. Unlike
+- `MB_LEN_MAX' this macro need not be a compile-time constant, and in
+- the GNU C library it is not.
+-
+- `MB_CUR_MAX' is defined in `stdlib.h'.
+-
+- Two different macros are necessary since strictly ISO C90 compilers
+-do not allow variable length array definitions, but still it is
+-desirable to avoid dynamic allocation. This incomplete piece of code
+-shows the problem:
+-
+- {
+- char buf[MB_LEN_MAX];
+- ssize_t len = 0;
+-
+- while (! feof (fp))
+- {
+- fread (&buf[len], 1, MB_CUR_MAX - len, fp);
+- /* ... process buf */
+- len -= used;
+- }
+- }
+-
+- The code in the inner loop is expected to have always enough bytes in
+-the array BUF to convert one multibyte character. The array BUF has to
+-be sized statically since many compilers do not allow a variable size.
+-The `fread' call makes sure that `MB_CUR_MAX' bytes are always
+-available in BUF. Note that it isn't a problem if `MB_CUR_MAX' is not
+-a compile-time constant.

+-
+-Representing the state of the conversion
+-----------------------------------------
+-
+- In the introduction of this chapter it was said that certain
+-character sets use a "stateful" encoding. That is, the encoded values
+-depend in some way on the previous bytes in the text.
+-
+- Since the conversion functions allow converting a text in more than
+-one step we must have a way to pass this information from one call of
+-the functions to another.
+-
+- - Data type: mbstate_t
+- A variable of type `mbstate_t' can contain all the information
+- about the "shift state" needed from one call to a conversion
+- function to another.
+-
+- `mbstate_t' is defined in `wchar.h'. It was introduced in
+- Amendment 1 to ISO C90.
+-
+- To use objects of type `mbstate_t' the programmer has to define such
+-objects (normally as local variables on the stack) and pass a pointer to
+-the object to the conversion functions. This way the conversion
+-function can update the object if the current multibyte character set
+-is stateful.
+-
+- There is no specific function or initializer to put the state object
+-in any specific state. The rules are that the object should always
+-represent the initial state before the first use, and this is achieved
+-by clearing the whole variable with code such as follows:
+-
+- {
+- mbstate_t state;
+- memset (&state, '\0', sizeof (state));
+- /* from now on STATE can be used. */
+- ...
+- }
+-
+- When using the conversion functions to generate output it is often
+-necessary to test whether the current state corresponds to the initial
+-state. This is necessary, for example, to decide whether to emit
+-escape sequences to set the state to the initial state at certain
+-sequence points. Communication protocols often require this.
+-
+- - Function: int mbsinit (const mbstate_t *PS)
+- The `mbsinit' function determines whether the state object pointed
+- to by PS is in the initial state. If PS is a null pointer or the
+- object is in the initial state the return value is nonzero.
+- Otherwise it is zero.
+-
+- `mbsinit' was introduced in Amendment 1 to ISO C90 and is declared
+- in `wchar.h'.
+-
+- Code using `mbsinit' often looks similar to this:
+-
+- {
+- mbstate_t state;
+- memset (&state, '\0', sizeof (state));
+- /* Use STATE. */
+- ...
+- if (! mbsinit (&state))
+- {
+- /* Emit code to return to initial state. */
+- const wchar_t empty[] = L"";
+- const wchar_t *srcp = empty;
+- wcsrtombs (outbuf, &srcp, outbuflen, &state);
+- }
+- ...
+- }
+-
+- The code to emit the escape sequence to get back to the initial
+-state is interesting. The `wcsrtombs' function can be used to
+-determine the necessary output code (*note Converting Strings::).
+-Please note that on GNU systems it is not necessary to perform this
+-extra action for the conversion from multibyte text to wide character
+-text since the wide character encoding is not stateful. But there is
+-nothing mentioned in any standard that prohibits making `wchar_t' using
+-a stateful encoding.

+-
+-Converting Single Characters
+-----------------------------
+-
+- The most fundamental of the conversion functions are those dealing
+-with single characters. Please note that this does not always mean
+-single bytes. But since there is very often a subset of the multibyte
+-character set that consists of single byte sequences, there are
+-functions to help with converting bytes. Frequently, ASCII is a subpart
+-of the multibyte character set. In such a scenario, each ASCII
+-character stands for itself, and all other characters have at least a
+-first byte that is beyond the range 0 to 127.
+-
+- - Function: wint_t btowc (int C)
+- The `btowc' function ("byte to wide character") converts a valid
+- single byte character C in the initial shift state into the wide
+- character equivalent using the conversion rules from the currently
+- selected locale of the `LC_CTYPE' category.
+-
+- If `(unsigned char) C' is no valid single byte multibyte character
+- or if C is `EOF', the function returns `WEOF'.
+-
+- Please note the restriction of C being tested for validity only in
+- the initial shift state. No `mbstate_t' object is used from which
+- the state information is taken, and the function also does not use
+- any static state.
+-
+- The `btowc' function was introduced in Amendment 1 to ISO C90 and
+- is declared in `wchar.h'.
+-
+- Despite the limitation that the single byte value always is
+-interpreted in the initial state this function is actually useful most
+-of the time. Most characters are either entirely single-byte character
+-sets or they are extension to ASCII. But then it is possible to write
+-code like this (not that this specific example is very useful):
+-
+- wchar_t *
+- itow (unsigned long int val)
+- {
+- static wchar_t buf[30];
+- wchar_t *wcp = &buf[29];
+- *wcp = L'\0';
+- while (val != 0)
+- {
+- *--wcp = btowc ('0' + val % 10);
+- val /= 10;
+- }
+- if (wcp == &buf[29])
+- *--wcp = L'0';
+- return wcp;
+- }
+-
+- Why is it necessary to use such a complicated implementation and not
+-simply cast `'0' + val % 10' to a wide character? The answer is that
+-there is no guarantee that one can perform this kind of arithmetic on
+-the character of the character set used for `wchar_t' representation.
+-In other situations the bytes are not constant at compile time and so
+-the compiler cannot do the work. In situations like this it is
+-necessary `btowc'.
+-
+-There also is a function for the conversion in the other direction.
+-
+- - Function: int wctob (wint_t C)
+- The `wctob' function ("wide character to byte") takes as the
+- parameter a valid wide character. If the multibyte representation
+- for this character in the initial state is exactly one byte long,
+- the return value of this function is this character. Otherwise
+- the return value is `EOF'.
+-
+- `wctob' was introduced in Amendment 1 to ISO C90 and is declared
+- in `wchar.h'.
+-
+- There are more general functions to convert single character from
+-multibyte representation to wide characters and vice versa. These
+-functions pose no limit on the length of the multibyte representation
+-and they also do not require it to be in the initial state.
+-
+- - Function: size_t mbrtowc (wchar_t *restrict PWC, const char
+- *restrict S, size_t N, mbstate_t *restrict PS)
+- The `mbrtowc' function ("multibyte restartable to wide character")
+- converts the next multibyte character in the string pointed to by
+- S into a wide character and stores it in the wide character string
+- pointed to by PWC. The conversion is performed according to the
+- locale currently selected for the `LC_CTYPE' category. If the
+- conversion for the character set used in the locale requires a
+- state, the multibyte string is interpreted in the state
+- represented by the object pointed to by PS. If PS is a null
+- pointer, a static, internal state variable used only by the
+- `mbrtowc' function is used.
+-
+- If the next multibyte character corresponds to the NUL wide
+- character, the return value of the function is 0 and the state
+- object is afterwards in the initial state. If the next N or fewer
+- bytes form a correct multibyte character, the return value is the
+- number of bytes starting from S that form the multibyte character.
+- The conversion state is updated according to the bytes consumed
+- in the conversion. In both cases the wide character (either the
+- `L'\0'' or the one found in the conversion) is stored in the
+- string pointed to by PWC if PWC is not null.
+-
+- If the first N bytes of the multibyte string possibly form a valid
+- multibyte character but there are more than N bytes needed to
+- complete it, the return value of the function is `(size_t) -2' and
+- no value is stored. Please note that this can happen even if N
+- has a value greater than or equal to `MB_CUR_MAX' since the input
+- might contain redundant shift sequences.
+-
+- If the first `n' bytes of the multibyte string cannot possibly form
+- a valid multibyte character, no value is stored, the global
+- variable `errno' is set to the value `EILSEQ', and the function
+- returns `(size_t) -1'. The conversion state is afterwards
+- undefined.
+-
+- `mbrtowc' was introduced in Amendment 1 to ISO C90 and is declared
+- in `wchar.h'.
+-
+- Use of `mbrtowc' is straightforward. A function that copies a
+-multibyte string into a wide character string while at the same time
+-converting all lowercase characters into uppercase could look like this
+-(this is not the final version, just an example; it has no error
+-checking, and sometimes leaks memory):
+-
+- wchar_t *
+- mbstouwcs (const char *s)
+- {
+- size_t len = strlen (s);
+- wchar_t *result = malloc ((len + 1) * sizeof (wchar_t));
+- wchar_t *wcp = result;
+- wchar_t tmp[1];
+- mbstate_t state;
+- size_t nbytes;
+-
+- memset (&state, '\0', sizeof (state));
+- while ((nbytes = mbrtowc (tmp, s, len, &state)) > 0)
+- {
+- if (nbytes >= (size_t) -2)
+- /* Invalid input string. */
+- return NULL;
+- *result++ = towupper (tmp[0]);
+- len -= nbytes;
+- s += nbytes;
+- }
+- return result;
+- }
+-
+- The use of `mbrtowc' should be clear. A single wide character is
+-stored in `TMP[0]', and the number of consumed bytes is stored in the
+-variable NBYTES. If the conversion is successful, the uppercase
+-variant of the wide character is stored in the RESULT array and the
+-pointer to the input string and the number of available bytes is
+-adjusted.
+-
+- The only non-obvious thing about `mbrtowc' might be the way memory
+-is allocated for the result. The above code uses the fact that there
+-can never be more wide characters in the converted results than there
+-are bytes in the multibyte input string. This method yields a
+-pessimistic guess about the size of the result, and if many wide
+-character strings have to be constructed this way or if the strings are
+-long, the extra memory required to be allocated because the input
+-string contains multibyte characters might be significant. The
+-allocated memory block can be resized to the correct size before
+-returning it, but a better solution might be to allocate just the right
+-amount of space for the result right away. Unfortunately there is no
+-function to compute the length of the wide character string directly
+-from the multibyte string. There is, however, a function that does
+-part of the work.
+-
+- - Function: size_t mbrlen (const char *restrict S, size_t N, mbstate_t
+- *PS)
+- The `mbrlen' function ("multibyte restartable length") computes
+- the number of at most N bytes starting at S, which form the next
+- valid and complete multibyte character.
+-
+- If the next multibyte character corresponds to the NUL wide
+- character, the return value is 0. If the next N bytes form a valid
+- multibyte character, the number of bytes belonging to this
+- multibyte character byte sequence is returned.
+-
+- If the the first N bytes possibly form a valid multibyte character
+- but the character is incomplete, the return value is `(size_t)
+- -2'. Otherwise the multibyte character sequence is invalid and
+- the return value is `(size_t) -1'.
+-
+- The multibyte sequence is interpreted in the state represented by
+- the object pointed to by PS. If PS is a null pointer, a state
+- object local to `mbrlen' is used.
+-
+- `mbrlen' was introduced in Amendment 1 to ISO C90 and is declared
+- in `wchar.h'.
+-
+- The attentive reader now will note that `mbrlen' can be implemented
+-as
+-
+- mbrtowc (NULL, s, n, ps != NULL ? ps : &internal)
+-
+- This is true and in fact is mentioned in the official specification.
+-How can this function be used to determine the length of the wide
+-character string created from a multibyte character string? It is not
+-directly usable, but we can define a function `mbslen' using it:
+-
+- size_t
+- mbslen (const char *s)
+- {
+- mbstate_t state;
+- size_t result = 0;
+- size_t nbytes;
+- memset (&state, '\0', sizeof (state));
+- while ((nbytes = mbrlen (s, MB_LEN_MAX, &state)) > 0)
+- {
+- if (nbytes >= (size_t) -2)
+- /* Something is wrong. */
+- return (size_t) -1;
+- s += nbytes;
+- ++result;
+- }
+- return result;
+- }
+-
+- This function simply calls `mbrlen' for each multibyte character in
+-the string and counts the number of function calls. Please note that
+-we here use `MB_LEN_MAX' as the size argument in the `mbrlen' call.
+-This is acceptable since a) this value is larger then the length of the
+-longest multibyte character sequence and b) we know that the string S
+-ends with a NUL byte, which cannot be part of any other multibyte
+-character sequence but the one representing the NUL wide character.
+-Therefore, the `mbrlen' function will never read invalid memory.
+-
+- Now that this function is available (just to make this clear, this
+-function is _not_ part of the GNU C library) we can compute the number
+-of wide character required to store the converted multibyte character
+-string S using
+-
+- wcs_bytes = (mbslen (s) + 1) * sizeof (wchar_t);
+-
+- Please note that the `mbslen' function is quite inefficient. The
+-implementation of `mbstouwcs' with `mbslen' would have to perform the
+-conversion of the multibyte character input string twice, and this
+-conversion might be quite expensive. So it is necessary to think about
+-the consequences of using the easier but imprecise method before doing
+-the work twice.
+-
+- - Function: size_t wcrtomb (char *restrict S, wchar_t WC, mbstate_t
+- *restrict PS)
+- The `wcrtomb' function ("wide character restartable to multibyte")
+- converts a single wide character into a multibyte string
+- corresponding to that wide character.
+-
+- If S is a null pointer, the function resets the state stored in
+- the objects pointed to by PS (or the internal `mbstate_t' object)
+- to the initial state. This can also be achieved by a call like
+- this:
+-
+- wcrtombs (temp_buf, L'\0', ps)
+-
+- since, if S is a null pointer, `wcrtomb' performs as if it writes
+- into an internal buffer, which is guaranteed to be large enough.
+-
+- If WC is the NUL wide character, `wcrtomb' emits, if necessary, a
+- shift sequence to get the state PS into the initial state followed
+- by a single NUL byte, which is stored in the string S.
+-
+- Otherwise a byte sequence (possibly including shift sequences) is
+- written into the string S. This only happens if WC is a valid wide
+- character (i.e., it has a multibyte representation in the
+- character set selected by locale of the `LC_CTYPE' category). If
+- WC is no valid wide character, nothing is stored in the strings S,
+- `errno' is set to `EILSEQ', the conversion state in PS is
+- undefined and the return value is `(size_t) -1'.
+-
+- If no error occurred the function returns the number of bytes
+- stored in the string S. This includes all bytes representing shift
+- sequences.
+-
+- One word about the interface of the function: there is no parameter
+- specifying the length of the array S. Instead the function
+- assumes that there are at least `MB_CUR_MAX' bytes available since
+- this is the maximum length of any byte sequence representing a
+- single character. So the caller has to make sure that there is
+- enough space available, otherwise buffer overruns can occur.
+-
+- `wcrtomb' was introduced in Amendment 1 to ISO C90 and is declared
+- in `wchar.h'.
+-
+- Using `wcrtomb' is as easy as using `mbrtowc'. The following
+-example appends a wide character string to a multibyte character string.
+-Again, the code is not really useful (or correct), it is simply here to
+-demonstrate the use and some problems.
+-
+- char *
+- mbscatwcs (char *s, size_t len, const wchar_t *ws)
+- {
+- mbstate_t state;
+- /* Find the end of the existing string. */
+- char *wp = strchr (s, '\0');
+- len -= wp - s;
+- memset (&state, '\0', sizeof (state));
+- do
+- {
+- size_t nbytes;
+- if (len < MB_CUR_LEN)
+- {
+- /* We cannot guarantee that the next
+- character fits into the buffer, so
+- return an error. */
+- errno = E2BIG;
+- return NULL;
+- }
+- nbytes = wcrtomb (wp, *ws, &state);
+- if (nbytes == (size_t) -1)
+- /* Error in the conversion. */
+- return NULL;
+- len -= nbytes;
+- wp += nbytes;
+- }
+- while (*ws++ != L'\0');
+- return s;
+- }
+-
+- First the function has to find the end of the string currently in the
+-array S. The `strchr' call does this very efficiently since a
+-requirement for multibyte character representations is that the NUL byte
+-is never used except to represent itself (and in this context, the end
+-of the string).
+-
+- After initializing the state object the loop is entered where the
+-first task is to make sure there is enough room in the array S. We
+-abort if there are not at least `MB_CUR_LEN' bytes available. This is
+-not always optimal but we have no other choice. We might have less
+-than `MB_CUR_LEN' bytes available but the next multibyte character
+-might also be only one byte long. At the time the `wcrtomb' call
+-returns it is too late to decide whether the buffer was large enough.
+-If this solution is unsuitable, there is a very slow but more accurate
+-solution.
+-
+- ...
+- if (len < MB_CUR_LEN)
+- {
+- mbstate_t temp_state;
+- memcpy (&temp_state, &state, sizeof (state));
+- if (wcrtomb (NULL, *ws, &temp_state) > len)
+- {
+- /* We cannot guarantee that the next
+- character fits into the buffer, so
+- return an error. */
+- errno = E2BIG;
+- return NULL;
+- }
+- }
+- ...
+-
+- Here we perform the conversion that might overflow the buffer so that
+-we are afterwards in the position to make an exact decision about the
+-buffer size. Please note the `NULL' argument for the destination
+-buffer in the new `wcrtomb' call; since we are not interested in the
+-converted text at this point, this is a nice way to express this. The
+-most unusual thing about this piece of code certainly is the duplication
+-of the conversion state object, but if a change of the state is
+-necessary to emit the next multibyte character, we want to have the
+-same shift state change performed in the real conversion. Therefore,
+-we have to preserve the initial shift state information.
+-
+- There are certainly many more and even better solutions to this
+-problem. This example is only provided for educational purposes.

+-Converting Multibyte and Wide Character Strings
+------------------------------------------------
+-
+- The functions described in the previous section only convert a single
+-character at a time. Most operations to be performed in real-world
+-programs include strings and therefore the ISO C standard also defines
+-conversions on entire strings. However, the defined set of functions
+-is quite limited; therefore, the GNU C library contains a few
+-extensions that can help in some important situations.
+-
+- - Function: size_t mbsrtowcs (wchar_t *restrict DST, const char
+- **restrict SRC, size_t LEN, mbstate_t *restrict PS)
+- The `mbsrtowcs' function ("multibyte string restartable to wide
+- character string") converts an NUL-terminated multibyte character
+- string at `*SRC' into an equivalent wide character string,
+- including the NUL wide character at the end. The conversion is
+- started using the state information from the object pointed to by
+- PS or from an internal object of `mbsrtowcs' if PS is a null
+- pointer. Before returning, the state object is updated to match
+- the state after the last converted character. The state is the
+- initial state if the terminating NUL byte is reached and converted.
+-
+- If DST is not a null pointer, the result is stored in the array
+- pointed to by DST; otherwise, the conversion result is not
+- available since it is stored in an internal buffer.
+-
+- If LEN wide characters are stored in the array DST before reaching
+- the end of the input string, the conversion stops and LEN is
+- returned. If DST is a null pointer, LEN is never checked.
+-
+- Another reason for a premature return from the function call is if
+- the input string contains an invalid multibyte sequence. In this
+- case the global variable `errno' is set to `EILSEQ' and the
+- function returns `(size_t) -1'.
+-
+- In all other cases the function returns the number of wide
+- characters converted during this call. If DST is not null,
+- `mbsrtowcs' stores in the pointer pointed to by SRC either a null
+- pointer (if the NUL byte in the input string was reached) or the
+- address of the byte following the last converted multibyte
+- character.
+-
+- `mbsrtowcs' was introduced in Amendment 1 to ISO C90 and is
+- declared in `wchar.h'.
+-
+- The definition of the `mbsrtowcs' function has one important
+-limitation. The requirement that DST has to be a NUL-terminated string
+-provides problems if one wants to convert buffers with text. A buffer
+-is normally no collection of NUL-terminated strings but instead a
+-continuous collection of lines, separated by newline characters. Now
+-assume that a function to convert one line from a buffer is needed.
+-Since the line is not NUL-terminated, the source pointer cannot
+-directly point into the unmodified text buffer. This means, either one
+-inserts the NUL byte at the appropriate place for the time of the
+-`mbsrtowcs' function call (which is not doable for a read-only buffer
+-or in a multi-threaded application) or one copies the line in an extra
+-buffer where it can be terminated by a NUL byte. Note that it is not
+-in general possible to limit the number of characters to convert by
+-setting the parameter LEN to any specific value. Since it is not known
+-how many bytes each multibyte character sequence is in length, one can
+-only guess.
+-
+- There is still a problem with the method of NUL-terminating a line
+-right after the newline character, which could lead to very strange
+-results. As said in the description of the `mbsrtowcs' function above
+-the conversion state is guaranteed to be in the initial shift state
+-after processing the NUL byte at the end of the input string. But this
+-NUL byte is not really part of the text (i.e., the conversion state
+-after the newline in the original text could be something different
+-than the initial shift state and therefore the first character of the
+-next line is encoded using this state). But the state in question is
+-never accessible to the user since the conversion stops after the NUL
+-byte (which resets the state). Most stateful character sets in use
+-today require that the shift state after a newline be the initial
+-state-but this is not a strict guarantee. Therefore, simply
+-NUL-terminating a piece of a running text is not always an adequate
+-solution and, therefore, should never be used in generally used code.
+-
+- The generic conversion interface (*note Generic Charset Conversion::)
+-does not have this limitation (it simply works on buffers, not
+-strings), and the GNU C library contains a set of functions that take
+-additional parameters specifying the maximal number of bytes that are
+-consumed from the input string. This way the problem of `mbsrtowcs''s
+-example above could be solved by determining the line length and
+-passing this length to the function.
+-
+- - Function: size_t wcsrtombs (char *restrict DST, const wchar_t
+- **restrict SRC, size_t LEN, mbstate_t *restrict PS)
+- The `wcsrtombs' function ("wide character string restartable to
+- multibyte string") converts the NUL-terminated wide character
+- string at `*SRC' into an equivalent multibyte character string and
+- stores the result in the array pointed to by DST. The NUL wide
+- character is also converted. The conversion starts in the state
+- described in the object pointed to by PS or by a state object
+- locally to `wcsrtombs' in case PS is a null pointer. If DST is a
+- null pointer, the conversion is performed as usual but the result
+- is not available. If all characters of the input string were
+- successfully converted and if DST is not a null pointer, the
+- pointer pointed to by SRC gets assigned a null pointer.
+-
+- If one of the wide characters in the input string has no valid
+- multibyte character equivalent, the conversion stops early, sets
+- the global variable `errno' to `EILSEQ', and returns `(size_t) -1'.
+-
+- Another reason for a premature stop is if DST is not a null
+- pointer and the next converted character would require more than
+- LEN bytes in total to the array DST. In this case (and if DEST is
+- not a null pointer) the pointer pointed to by SRC is assigned a
+- value pointing to the wide character right after the last one
+- successfully converted.
+-
+- Except in the case of an encoding error the return value of the
+- `wcsrtombs' function is the number of bytes in all the multibyte
+- character sequences stored in DST. Before returning the state in
+- the object pointed to by PS (or the internal object in case PS is
+- a null pointer) is updated to reflect the state after the last
+- conversion. The state is the initial shift state in case the
+- terminating NUL wide character was converted.
+-
+- The `wcsrtombs' function was introduced in Amendment 1 to ISO C90
+- and is declared in `wchar.h'.
+-
+- The restriction mentioned above for the `mbsrtowcs' function applies
+-here also. There is no possibility of directly controlling the number
+-of input characters. One has to place the NUL wide character at the
+-correct place or control the consumed input indirectly via the
+-available output array size (the LEN parameter).
+-
+- - Function: size_t mbsnrtowcs (wchar_t *restrict DST, const char
+- **restrict SRC, size_t NMC, size_t LEN, mbstate_t *restrict
+- PS)
+- The `mbsnrtowcs' function is very similar to the `mbsrtowcs'
+- function. All the parameters are the same except for NMC, which is
+- new. The return value is the same as for `mbsrtowcs'.
+-
+- This new parameter specifies how many bytes at most can be used
+- from the multibyte character string. In other words, the
+- multibyte character string `*SRC' need not be NUL-terminated. But
+- if a NUL byte is found within the NMC first bytes of the string,
+- the conversion stops here.
+-
+- This function is a GNU extension. It is meant to work around the
+- problems mentioned above. Now it is possible to convert a buffer
+- with multibyte character text piece for piece without having to
+- care about inserting NUL bytes and the effect of NUL bytes on the
+- conversion state.
+-
+- A function to convert a multibyte string into a wide character string
+-and display it could be written like this (this is not a really useful
+-example):
+-
+- void
+- showmbs (const char *src, FILE *fp)
+- {
+- mbstate_t state;
+- int cnt = 0;
+- memset (&state, '\0', sizeof (state));
+- while (1)
+- {
+- wchar_t linebuf[100];
+- const char *endp = strchr (src, '\n');
+- size_t n;
+-
+- /* Exit if there is no more line. */
+- if (endp == NULL)
+- break;
+-
+- n = mbsnrtowcs (linebuf, &src, endp - src, 99, &state);
+- linebuf[n] = L'\0';
+- fprintf (fp, "line %d: \"%S\"\n", linebuf);
+- }
+- }
+-
+- There is no problem with the state after a call to `mbsnrtowcs'.
+-Since we don't insert characters in the strings that were not in there
+-right from the beginning and we use STATE only for the conversion of
+-the given buffer, there is no problem with altering the state.
+-
+- - Function: size_t wcsnrtombs (char *restrict DST, const wchar_t
+- **restrict SRC, size_t NWC, size_t LEN, mbstate_t *restrict
+- PS)
+- The `wcsnrtombs' function implements the conversion from wide
+- character strings to multibyte character strings. It is similar to
+- `wcsrtombs' but, just like `mbsnrtowcs', it takes an extra
+- parameter, which specifies the length of the input string.
+-
+- No more than NWC wide characters from the input string `*SRC' are
+- converted. If the input string contains a NUL wide character in
+- the first NWC characters, the conversion stops at this place.
+-
+- The `wcsnrtombs' function is a GNU extension and just like
+- `mbsnrtowcs' helps in situations where no NUL-terminated input
+- strings are available.

++ Returns 'dst'.
++
++ Memcpy handles short copies (< 32-bytes) using an unaligned
++ word lwz/stw loop. The tail (remaining 1-3) bytes is handled with the
++ appropriate combination of byte and halfword load/stores. There is no
++ attempt to optimize the alignment of short moves. The 64-bit
++ implementations of POWER3 and POWER4 do a reasonable job of handling
++ unligned load/stores that do not cross 32-byte boundries.
++
++ Longer moves (>= 32-bytes) justify the effort to get at least the
++ destination doubleword (8-byte) aligned. Further optimization is
++ posible when both source and destination are doubleword aligned.
++ Each case has a optimized unrolled loop. */
