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 . 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 . 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). -+ -+ -+Ulrich Drepper -diff -u -udbrN glibc-2.3.2/README.template glibc-2.3.2-200304020432/README.template ---- glibc-2.3.2/README.template Thu Jan 1 01:00:00 1970 -+++ glibc-2.3.2-200304020432/README.template Wed Oct 2 23:16:42 2002 -@@ -0,0 +1,87 @@ -+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.

This number does not include the terminating null -- character, which is present if the number is less than SIZE. -- -- --File: libc.info, Node: Shift State, Prev: Non-reentrant String Conversion, Up: Non-reentrant Conversion -- --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. -- -- --File: libc.info, Node: Generic Charset Conversion, Prev: Non-reentrant Conversion, Up: Character Set Handling -- --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. -- --* Menu: -- --* Generic Conversion Interface:: Generic Character Set Conversion Interface. --* iconv Examples:: A complete `iconv' example. --* Other iconv Implementations:: Some Details about other `iconv' -- Implementations. --* glibc iconv Implementation:: The `iconv' Implementation in the GNU C -- library. -- -- --File: libc.info, Node: Generic Conversion Interface, Next: iconv Examples, Up: Generic Charset Conversion -- --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. -- -- --File: libc.info, Node: iconv Examples, Next: Other iconv Implementations, Prev: Generic Conversion Interface, Up: Generic Charset Conversion -- --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.

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.

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. -- -- --File: libc.info, Node: Other iconv Implementations, Next: glibc iconv Implementation, Prev: iconv Examples, Up: Generic Charset Conversion -- --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. -- -diff -u -udbrN glibc-2.3.2/manual/libc.info-11 glibc-2.3.2-200304020432/manual/libc.info-11 ---- glibc-2.3.2/manual/libc.info-11 Sat Mar 1 02:39:41 2003 -+++ glibc-2.3.2-200304020432/manual/libc.info-11 Thu Jan 1 01:00:00 1970 -@@ -1,1041 +0,0 @@ --This is libc.info, produced by makeinfo version 4.2 from libc.texinfo. -- --INFO-DIR-SECTION GNU libraries --START-INFO-DIR-ENTRY --* Libc: (libc).

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, -- int do_flush) -- { -- struct __gconv_step *next_step = step + 1; -- struct __gconv_step_data *next_data = data + 1; -- gconv_fct fct = next_step->__fct; -- int status; -- -- /* If the function is called with no input this means we have -- to reset to the initial state.

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 -- #include -- #include -- #include -- -- 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.

The attributes and behavior it -- provides are specified in the ISO C standard.

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. -- -- --File: libc.info, Node: Locale Information, Next: Formatting Numbers, Prev: Standard Locales, Up: Locales -- --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'.

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.

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'. -- -- --File: libc.info, Node: The message catalog files, Next: The gencat program, Prev: The catgets Functions, Up: Message catalogs a la X/Open -- --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. -- -- --File: libc.info, Node: The gencat program, Next: Common Usage, Prev: The message catalog files, Up: Message catalogs a la X/Open -- --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.

If the output is written to --standard output no merging takes place. -- --The following table shows the options understood by the `gencat' --program.

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 -- 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 -- #include -- #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'.

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. -- -- --File: libc.info, Node: Locating gettext catalog, Next: Advanced gettext functions, Prev: Translation with gettext, Up: Message catalogs with gettext -- --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. -- -diff -u -udbrN glibc-2.3.2/manual/libc.info-14 glibc-2.3.2-200304020432/manual/libc.info-14 ---- glibc-2.3.2/manual/libc.info-14 Sat Mar 1 02:39:41 2003 -+++ glibc-2.3.2-200304020432/manual/libc.info-14 Thu Jan 1 01:00:00 1970 -@@ -1,1159 +0,0 @@ --This is libc.info, produced by makeinfo version 4.2 from libc.texinfo. -- --INFO-DIR-SECTION GNU libraries --START-INFO-DIR-ENTRY --* Libc: (libc).

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.

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 --themselves. This is only logical. There is no need to disambiguate --the strings (since they are never used as keys for a search) and one --also saves quite some memory and disk space by doing this. -- -- --File: libc.info, Node: Using gettextized software, Prev: GUI program problems, Up: Message catalogs with gettext -- --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. -- -- --File: libc.info, Node: Helper programs for gettext, Prev: Message catalogs with gettext, Up: The Uniforum approach -- --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.

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.

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. -- -- --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.

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. -- -diff -u -udbrN glibc-2.3.2/manual/libc.info-15 glibc-2.3.2-200304020432/manual/libc.info-15 ---- glibc-2.3.2/manual/libc.info-15 Sat Mar 1 02:39:41 2003 -+++ glibc-2.3.2-200304020432/manual/libc.info-15 Thu Jan 1 01:00:00 1970 -@@ -1,1197 +0,0 @@ --This is libc.info, produced by makeinfo version 4.2 from libc.texinfo. -- --INFO-DIR-SECTION GNU libraries --START-INFO-DIR-ENTRY --* Libc: (libc).

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. -- -- --File: libc.info, Node: Pattern Matching, Next: I/O Overview, Prev: Searching and Sorting, Up: Top -- --Pattern Matching --**************** -- -- The GNU C Library provides pattern matching facilities for two kinds --of patterns: regular expressions and file-name wildcards.

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'.

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'.

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.

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. -- -- --File: libc.info, Node: Flags for Globbing, Next: More Flags for Globbing, Prev: Calling Glob, Up: Globbing -- --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'. -- -- --File: libc.info, Node: More Flags for Globbing, Prev: Flags for Globbing, Up: Globbing -- --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'. -- -- --File: libc.info, Node: Regular Expressions, Next: Word Expansion, Prev: Globbing, Up: Pattern Matching -- --Regular Expression Matching --=========================== -- -- The GNU C library supports two interfaces for matching regular --expressions.

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'. -- -- --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. -- -- --File: libc.info, Node: Regexp Cleanup, Prev: Subexpression Complications, Up: Regular Expressions -- --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 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.

Once you have closed a --stream or file descriptor, you cannot do any more input or output --operations on it. -- --* Menu: -- --* Streams and File Descriptors:: The GNU Library provides two ways -- to access the contents of files. --* File Position:: The number of bytes from the -- beginning of the file. -- -- --File: libc.info, Node: Streams and File Descriptors, Next: File Position, Up: I/O Concepts -- --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. -- -- --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: libc.info, Node: File Names, Prev: I/O Concepts, Up: I/O Overview -- --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. -- --* Menu: -- --* Directories:: Directories contain entries for files. --* File Name Resolution:: A file name specifies how to look up a file. --* File Name Errors:: Error conditions relating to file names. --* File Name Portability:: File name portability and syntax issues. -- -- --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::. -- -- --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: libc.info, Node: File Name Errors, Next: File Name Portability, Prev: File Name Resolution, Up: File Names -- --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::. -- -- --File: libc.info, Node: File Name Portability, Prev: File Name Errors, Up: File Names -- --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. -- -- --File: libc.info, Node: I/O on Streams, Next: Low-Level I/O, Prev: I/O Overview, Up: Top -- --Input/Output on Streams --*********************** -- -- This chapter describes the functions for creating streams and --performing input and output operations on them.

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. -- -- --File: libc.info, Node: Standard Streams, Next: Opening Streams, Prev: Streams, Up: I/O on Streams -- --Standard Streams --================ -- -- When the `main' function of your program is invoked, it already has --three predefined streams open and available for use. These represent --the "standard" input and output channels that have been established for --the process. -- -- 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::). -- -- --File: libc.info, Node: Opening Streams, Next: Closing Streams, Prev: Standard Streams, Up: I/O on Streams -- --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'. -- -- --File: libc.info, Node: Closing Streams, Next: Streams and Threads, Prev: Opening Streams, Up: I/O on Streams -- --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.

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). -- -- --File: libc.info, Node: Streams and I18N, Next: Simple Output, Prev: Streams and Threads, Up: I/O on Streams -- --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'. -- -- --File: libc.info, Node: Simple Output, Next: Character Input, Prev: Streams and I18N, Up: I/O on Streams -- --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.

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'. -- -- --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 -- #include -- -- 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)); -- ungetc (c, stream); -- } -- -- --File: libc.info, Node: Block Input/Output, Next: Formatted Output, Prev: Unreading, Up: I/O on Streams -- --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. -- -- This function is a GNU extension. -- -- --File: libc.info, Node: Formatted Output, Next: Customizing Printf, Prev: Block Input/Output, Up: I/O on Streams -- --Formatted Output --================ -- -- 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.

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. -- -- --File: libc.info, Node: Output Conversion Syntax, Next: Table of Output Conversions, Prev: Formatted Output Basics, Up: Formatted Output -- --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.

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.

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.

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.

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.

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'.

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 scanf ("%a[a-zA-Z0-9] = %a[^\n]\n", -- &variable, &value)) -- { -- invalid_input_error (); -- return 0; -- } -- -- ... -- } -- -- --File: libc.info, Node: Other Input Conversions, Next: Formatted Input Functions, Prev: Dynamic String Input, Up: Formatted Input -- --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. -- -- --File: libc.info, Node: Formatted Input Functions, Next: Variable Arguments Input, Prev: Other Input Conversions, Up: Formatted Input -- --Formatted Input Functions --------------------------- -- -- Here are the descriptions of the functions for performing formatted --input.

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. -- -- --File: libc.info, Node: Binary Streams, Next: File Positioning, Prev: Error Recovery, Up: I/O on Streams -- --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. -- -- --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'. -- -diff -u -udbrN glibc-2.3.2/manual/libc.info-2 glibc-2.3.2-200304020432/manual/libc.info-2 ---- glibc-2.3.2/manual/libc.info-2 Sat Mar 1 02:39:41 2003 -+++ glibc-2.3.2-200304020432/manual/libc.info-2 Thu Jan 1 01:00:00 1970 -@@ -1,1004 +0,0 @@ --This is libc.info, produced by makeinfo version 4.2 from libc.texinfo. -- --INFO-DIR-SECTION GNU libraries --START-INFO-DIR-ENTRY --* Libc: (libc).

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.

But if you are concerned about --making your programs compatible with these standards, or portable to --operating systems other than GNU, this can affect how you use the --library. This section gives you an overview of these standards, so that --you will know what they are when they are mentioned in other parts of --the manual. -- -- *Note Library Summary::, for an alphabetical list of the functions --and other symbols provided by the library.

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 --not aim for completeness. -- -- --File: libc.info, Node: POSIX, Next: Berkeley Unix, Prev: ISO C, Up: Standards and Portability -- --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::). -- -- --File: libc.info, Node: Berkeley Unix, Next: SVID, Prev: POSIX, Up: Standards and Portability -- --Berkeley Unix --------------- -- -- 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 BSD facilities include symbolic links (*note Symbolic Links::), --the `select' function (*note Waiting for I/O::), the BSD signal --functions (*note BSD Signal Handling::), and sockets (*note Sockets::). -- -- --File: libc.info, Node: SVID, Next: XPG, Prev: Berkeley Unix, Up: Standards and Portability -- --SVID (The System V Interface Description) ------------------------------------------- -- -- 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 --`drand48' families of functions, `fmtmsg' and several of the --mathematical functions. -- -- --File: libc.info, Node: XPG, Prev: SVID, Up: Standards and Portability -- --XPG (The X/Open Portability Guide) ------------------------------------ -- -- The X/Open Portability Guide, published by the X/Open Company, Ltd., --is a more general standard than POSIX. X/Open owns the Unix copyright --and the XPG specifies the requirements for systems which are intended --to be a Unix system. -- -- 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 --available in System V and BSD systems. Some of the really bad mistakes --in System V systems were corrected, though. Since fulfilling the XPG --standard with the Unix extensions is a precondition for getting the --Unix brand chances are good that the functionality is available on --commercial systems. -- -- --File: libc.info, Node: Using the Library, Next: Roadmap to the Manual, Prev: Standards and Portability, Up: Introduction -- --Using the Library --================= -- -- This section describes some of the practical issues involved in using --the GNU C library. -- --* Menu: -- --* Header Files:: How to include the header files in your -- programs. --* Macro Definitions:: Some functions in the library may really -- be implemented as macros. --* Reserved Names:: The C standard reserves some names for -- the library, and some for users. --* Feature Test Macros:: How to control what names are defined. -- -- --File: libc.info, Node: Header Files, Next: Macro Definitions, Up: Using the Library -- --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 -- --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. -- -- --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 -- 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 -- 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. -- -- --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. -- -- --File: libc.info, Node: Feature Test Macros, Prev: Reserved Names, Up: Using the Library -- --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. -- -- --File: libc.info, Node: Roadmap to the Manual, Prev: Using the Library, Up: Introduction -- --Roadmap to the Manual --===================== -- -- Here is an overview of the contents of the remaining chapters of --this manual. -- -- * *Note Error Reporting::, describes how errors detected by the -- library are reported. -- -- * *Note Language Features::, contains information about library -- support for standard parts of the C language, including things -- like the `sizeof' operator and the symbolic constant `NULL', how -- to write functions accepting variable numbers of arguments, and -- constants describing the ranges and other properties of the -- numerical types.

This gives you a --summary of its syntax and a pointer to where you can find a more --detailed description. This appendix is particularly useful if you just --want to verify the order and type of arguments to a function, for --example. It also tells you what standard or system each function, --variable, or macro is derived from. -- -- --File: libc.info, Node: Error Reporting, Next: Memory, Prev: Introduction, Up: Top -- --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. -- --* Menu: -- --* Checking for Errors:: How errors are reported by library functions. --* Error Codes:: Error code macros; all of these expand -- into integer constant values. --* Error Messages:: Mapping error codes onto error messages. -- -- --File: libc.info, Node: Checking for Errors, Next: Error Codes, Up: Error Reporting -- --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. -- -diff -u -udbrN glibc-2.3.2/manual/libc.info-20 glibc-2.3.2-200304020432/manual/libc.info-20 ---- glibc-2.3.2/manual/libc.info-20 Sat Mar 1 02:39:41 2003 -+++ glibc-2.3.2-200304020432/manual/libc.info-20 Thu Jan 1 01:00:00 1970 -@@ -1,1137 +0,0 @@ --This is libc.info, produced by makeinfo version 4.2 from libc.texinfo. -- --INFO-DIR-SECTION GNU libraries --START-INFO-DIR-ENTRY --* Libc: (libc).

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.

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::. -- -- --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.

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.

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'.

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::).

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 -- -- 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::).

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.

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.

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 (*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.

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). -- -- --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.

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.

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.

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'.

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.

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 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'.

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.

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. -- -- --File: libc.info, Node: Stream/Descriptor Precautions, Next: Scatter-Gather, Prev: Descriptors and Streams, Up: Low-Level I/O -- --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. -- -- --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. -- -- --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::. -- -- --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::. -- -- --File: libc.info, Node: Scatter-Gather, Next: Memory-mapped I/O, Prev: Stream/Descriptor Precautions, Up: Low-Level I/O -- --Fast Scatter-Gather I/O --======================= -- -- Some applications may need to read or write data to multiple buffers, --which are separated in memory.

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. -- -diff -u -udbrN glibc-2.3.2/manual/libc.info-22 glibc-2.3.2-200304020432/manual/libc.info-22 ---- glibc-2.3.2/manual/libc.info-22 Sat Mar 1 02:39:41 2003 -+++ glibc-2.3.2-200304020432/manual/libc.info-22 Thu Jan 1 01:00:00 1970 -@@ -1,1103 +0,0 @@ --This is libc.info, produced by makeinfo version 4.2 from libc.texinfo. -- --INFO-DIR-SECTION GNU libraries --START-INFO-DIR-ENTRY --* Libc: (libc).

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.

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.

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 --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'.

The --implementation of these functions can be done using support in the --kernel (if available) or using an implementation based on threads at --userlevel.

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.

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.

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.

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).

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: libc.info, Node: Descriptor Flags, Next: File Status Flags, Prev: Duplicating Descriptors, Up: Low-Level I/O -- --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.

(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_RDONLY -- Open the file for read access. -- -- - 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.) -- -- --File: libc.info, Node: Open-time Flags, Next: Operating Modes, Prev: Access Modes, Up: File Status Flags -- --Open-time Flags ----------------- -- -- The open-time flags specify options affecting how `open' will behave. --These options are not preserved once the file is open.

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.

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.

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.

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. -- -- --File: libc.info, Node: Getting File Status Flags, Prev: Operating Modes, Up: File Status Flags -- --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.

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.

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.

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. -- -- --File: libc.info, Node: IOCTLs, Prev: Interrupt Input, Up: Low-Level I/O -- --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.

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'.

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. -- -- --File: libc.info, Node: Accessing Directories, Next: Working with Directory Trees, Prev: Working Directory, Up: File System Interface -- --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.

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::. -- -- --File: libc.info, Node: Opening a Directory, Next: Reading/Closing Directory, Prev: Directory Entries, Up: Accessing Directories -- --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'. -- -- --File: libc.info, Node: Reading/Closing Directory, Next: Simple Directory Lister, Prev: Opening a Directory, Up: Accessing Directories -- --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. -- -- --File: libc.info, Node: Simple Directory Lister, Next: Random Access Directory, Prev: Reading/Closing Directory, Up: Accessing Directories -- --Simple Program to List a Directory ------------------------------------ -- -- Here's a simple program that prints the names of the files in the --current working directory: -- -- #include -- #include -- #include -- -- int -- main (void) -- { -- DIR *dp; -- struct dirent *ep; -- -- dp = opendir ("./"); -- if (dp != NULL) -- { -- while (ep = readdir (dp)) -- 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.

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::).

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. -- -- --File: libc.info, Node: Hard Links, Next: Symbolic Links, Prev: Working with Directory Trees, Up: File System Interface -- --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.

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. -- -diff -u -udbrN glibc-2.3.2/manual/libc.info-25 glibc-2.3.2-200304020432/manual/libc.info-25 ---- glibc-2.3.2/manual/libc.info-25 Sat Mar 1 02:39:41 2003 -+++ glibc-2.3.2-200304020432/manual/libc.info-25 Thu Jan 1 01:00:00 1970 -@@ -1,1163 +0,0 @@ --This is libc.info, produced by makeinfo version 4.2 from libc.texinfo. -- --INFO-DIR-SECTION GNU libraries --START-INFO-DIR-ENTRY --* Libc: (libc).

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.

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.

This data type is defined in `time.h'.

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.

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. -- -- --File: libc.info, Node: Making Special Files, Next: Temporary Files, Prev: File Attributes, Up: File System Interface -- --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.

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.

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. -- -- --File: libc.info, Node: Pipes and FIFOs, Next: Sockets, Prev: File System Interface, Up: Top -- --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.

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.

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.

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 --"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. -- -- --File: libc.info, Node: Communication Styles, Next: Socket Addresses, Prev: Socket Concepts, Up: Sockets -- --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. -- -- --File: libc.info, Node: Socket Addresses, Next: Interface Naming, Prev: Communication Styles, Up: Sockets -- --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'. -- --* Menu: -- --* Address Formats:: About `struct sockaddr'. --* Setting Address:: Binding an address to a socket. --* Reading Address:: Reading the address of a socket. -- -- --File: libc.info, Node: Address Formats, Next: Setting Address, Up: Socket Addresses -- --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.

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'. -- -- --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::.

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.

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.

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.

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'.

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.

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.

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.

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. -- -- `unsigned long int n_net' -- This is the network number. Network numbers are returned in -- host byte order; see *Note Byte Order::. -- -- Use the `getnetbyname' or `getnetbyaddr' functions to search the --networks database for information about a specific network. The --information is returned in a statically-allocated structure; you must --copy the information if you need to save it. -- -- - Function: struct netent * getnetbyname (const char *NAME) -- The `getnetbyname' function returns information about the network -- named NAME. It returns a null pointer if there is no such network. -- -- - Function: struct netent * getnetbyaddr (unsigned long int NET, int -- TYPE) -- The `getnetbyaddr' function returns information about the network -- of type TYPE with number NET. You should specify a value of -- `AF_INET' for the TYPE argument for Internet networks. -- -- `getnetbyaddr' returns a null pointer if there is no such network. -- -- You can also scan the networks database using `setnetent', --`getnetent' and `endnetent'. Be careful when using these functions --because they are not reentrant. -- -- - Function: void setnetent (int STAYOPEN) -- This function opens and rewinds the networks database. -- -- If the STAYOPEN argument is nonzero, this sets a flag so that -- subsequent calls to `getnetbyname' or `getnetbyaddr' 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 netent * getnetent (void) -- This function returns the next entry in the networks database. It -- returns a null pointer if there are no more entries. -- -- - Function: void endnetent (void) -- This function closes the networks database. -- -- --File: libc.info, Node: Low-Level Terminal Interface, Next: Syslog, Prev: Sockets, Up: Top -- --Low-Level Terminal Interface --**************************** -- -- This chapter describes functions that are specific to terminal --devices.

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.

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. -- -- --File: libc.info, Node: I/O Queues, Next: Canonical or Not, Prev: Is It a Terminal, Up: Low-Level Terminal Interface -- --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. -- -- --File: libc.info, Node: Canonical or Not, Next: Terminal Modes, Prev: I/O Queues, Up: Low-Level Terminal Interface -- --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::. -- -- --File: libc.info, Node: Terminal Modes, Next: BSD Terminal Modes, Prev: Canonical or Not, Up: Low-Level Terminal Interface -- --Terminal Modes --============== -- -- This section describes the various terminal attributes that control --how input and output are done.

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. -- -- --File: libc.info, Node: Mode Functions, Next: Setting Modes, Prev: Mode Data Types, Up: Terminal Modes -- --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. -- -- --File: libc.info, Node: Setting Modes, Next: Input Modes, Prev: Mode Functions, Up: Terminal 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; -- } -- -- --File: libc.info, Node: Input Modes, Next: Output Modes, Prev: Setting Modes, Up: Terminal Modes -- --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 and 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 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. -- -- --File: libc.info, Node: Output Modes, Next: Control Modes, Prev: Input Modes, Up: Terminal Modes -- --Output Modes -------------- -- -- This section describes the terminal flags and fields that control how --output characters are translated and padded for display.

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.

It enables special display of the -- KILL character by erasing on the screen the entire line that has -- been killed.

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.

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.

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 ) 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.

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.

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.

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 -- #include -- #include -- #include -- -- 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'. -- -- --File: libc.info, Node: Memory, Next: Character Handling, Prev: Error Reporting, Up: Top -- --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. -- --* Menu: -- --* Memory Concepts:: An introduction to concepts and terminology. --* Memory Allocation:: Allocating storage for your program data --* Locking Pages:: Preventing page faults --* Resizing the Data Segment:: `brk', `sbrk' -- -- Memory mapped I/O is not discussed in this chapter. *Note --Memory-mapped I/O::. -- -- --File: libc.info, Node: Memory Concepts, Next: Memory Allocation, Up: 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. -- -- -- --File: libc.info, Node: Memory Allocation, Next: Locking Pages, Prev: Memory Concepts, Up: Memory -- --Allocating Storage For Program Data --=================================== -- -- This section covers how ordinary programs manage storage for their --data, including the famous `malloc' function and some fancier facilities --special the GNU C library and GNU Compiler. -- --* Menu: -- --* Memory Allocation and C:: How to get different kinds of allocation in C. --* Unconstrained Allocation:: The `malloc' facility allows fully general -- dynamic allocation. --* Allocation Debugging:: Finding memory leaks and not freed memory. --* Obstacks:: Obstacks are less general than malloc -- but more efficient and convenient. --* Variable Size Automatic:: Allocation of variable-sized blocks -- of automatic storage that are freed when the -- calling function returns. -- -- --File: libc.info, Node: Memory Allocation and C, Next: Unconstrained Allocation, Up: Memory Allocation -- --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; -- } -- -- --File: libc.info, Node: Unconstrained Allocation, Next: Allocation Debugging, Prev: Memory Allocation and C, Up: Memory Allocation -- --Unconstrained Allocation -------------------------- -- -- 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). -- --* Menu: -- --* Basic Allocation:: Simple use of `malloc'. --* Malloc Examples:: Examples of `malloc'. `xmalloc'. --* Freeing after Malloc:: Use `free' to free a block you -- got with `malloc'. --* Changing Block Size:: Use `realloc' to make a block -- bigger or smaller. --* Allocating Cleared Space:: Use `calloc' to allocate a -- block and clear it. --* Efficiency and Malloc:: Efficiency considerations in use of -- these functions. --* Aligned Memory Blocks:: Allocating specially aligned memory. --* Malloc Tunable Parameters:: Use `mallopt' to adjust allocation -- parameters. --* Heap Consistency Checking:: Automatic checking for errors. --* Hooks for Malloc:: You can use these hooks for debugging -- programs that use `malloc'. --* Statistics of Malloc:: Getting information about how much -- memory your program is using. --* Summary of Malloc:: Summary of `malloc' and related functions. -- -- --File: libc.info, Node: Basic Allocation, Next: Malloc Examples, Up: Unconstrained Allocation -- --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. -- -- --File: libc.info, Node: Malloc Examples, Next: Freeing after Malloc, Prev: Basic Allocation, Up: Unconstrained Allocation -- --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::). -- -diff -u -udbrN glibc-2.3.2/manual/libc.info-30 glibc-2.3.2-200304020432/manual/libc.info-30 ---- glibc-2.3.2/manual/libc.info-30 Sat Mar 1 02:39:41 2003 -+++ glibc-2.3.2-200304020432/manual/libc.info-30 Thu Jan 1 01:00:00 1970 -@@ -1,1306 +0,0 @@ --This is libc.info, produced by makeinfo version 4.2 from libc.texinfo. -- --INFO-DIR-SECTION GNU libraries --START-INFO-DIR-ENTRY --* Libc: (libc).

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.

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.

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::.

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 -- -- 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. -- -- -- --File: libc.info, Node: syslog; vsyslog, Next: closelog, Prev: openlog, Up: Submitting Syslog Messages -- --syslog, vsyslog ----------------- -- -- 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.

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 (LOG_MAKEPRI(LOG_LOCAL1, LOG_ERROR), -- "Unable to make network connection to %s.

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. -- --* Menu: -- --* ISO Random:: `rand' and friends. --* BSD Random:: `random' and friends. --* SVID Random:: `drand48' and friends. -- -- --File: libc.info, Node: ISO Random, Next: BSD Random, Up: Pseudo-Random Numbers -- --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. -- -- --File: libc.info, Node: BSD Random, Next: SVID Random, Prev: ISO Random, Up: Pseudo-Random Numbers -- --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.

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. -- -- --File: libc.info, Node: FP Function Optimizations, Prev: Pseudo-Random Numbers, Up: Mathematics -- --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.

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. -- -- --File: libc.info, Node: Infinity and NaN, Next: Status bit operations, Prev: FP Exceptions, Up: Floating Point Errors -- --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.

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'.

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. -- -- --File: libc.info, Node: Rounding, Next: Control Functions, Prev: Floating Point Errors, Up: Arithmetic -- --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. -- -- --File: libc.info, Node: Control Functions, Next: Arithmetic Functions, Prev: Rounding, Up: Arithmetic -- --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.

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. --*Note Parsing of Integers::. -- -- --File: libc.info, Node: System V Number Conversion, Prev: Parsing of Numbers, Up: Arithmetic -- --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. -- -- --File: libc.info, Node: Date and Time, Next: Resource Usage And Limitation, Prev: Arithmetic, Up: Top -- --Date and Time --************* -- -- This chapter describes functions for manipulating dates and times, --including functions for determining what time it is and conversion --between different time representations. -- --* Menu: -- --* Time Basics:: Concepts and definitions. --* Elapsed Time:: Data types to represent elapsed times --* Processor And CPU Time:: Time a program has spent executing. --* Calendar Time:: Manipulation of ``real'' dates and times. --* Setting an Alarm:: Sending a signal after a specified time. --* Sleeping:: Waiting for a period of time. -- -- --File: libc.info, Node: Time Basics, Next: Elapsed Time, Up: Date and Time -- --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. -- -- --File: libc.info, Node: Elapsed Time, Next: Processor And CPU Time, Prev: Time Basics, Up: Date and Time -- --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. -- -- --File: libc.info, Node: Processor And CPU Time, Next: Calendar Time, Prev: Elapsed Time, Up: Date and Time -- --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, --and to control it, *Note Resource Usage And Limitation::. -- --* Menu: -- --* CPU Time:: The `clock' function. --* Processor Time:: The `times' function. -- -- --File: libc.info, Node: CPU Time, Next: Processor Time, Up: Processor And CPU Time -- --CPU Time Inquiry ------------------ -- -- To get a process' CPU time, you can use the `clock' function.

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 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', 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.

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. -- -- -- --File: libc.info, Node: High Accuracy Clock, Next: Formatting Calendar Time, Prev: Broken-down Time, Up: Calendar Time -- --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.

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.

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.

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'.

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.

Leap seconds are not counted unless leap -- second support is available. -- -- `%s' is a GNU extension following a GNU extension to -- `strftime'. -- -- `%S' -- 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 -- value is `61', a result of a decision to allow double leap -- seconds. You will not see the value `61' because no minute -- has more than one leap second, but the myth persists. -- -- `%OS' -- Same as `%S' but using the locale's alternative numeric -- symbols. -- -- `%T' -- Equivalent to the use of `%H:%M:%S' in this place. -- -- `%u' -- The day of the week as a decimal number (range `1' through -- `7'), Monday being `1'. -- -- Leading zeroes are permitted but not required. -- -- _Note:_ Currently, this is not fully implemented.

The format -- is recognized, input is consumed but no field in TM is set. -- -- `%Ow' -- Same as `%w' but using the locale's alternative numeric -- symbols. -- -- `%W' -- The week number of the current year as a decimal number -- (range `0' through `53'). -- -- Leading zeroes are permitted but not required. -- -- _Note:_ Currently, this is not fully implemented. The format -- is recognized, input is consumed but no field in TM is set. -- -- `%OW' -- Same as `%W' but using the locale's alternative numeric -- symbols. -- -- `%x' -- The date using the locale's date format. -- -- `%Ex' -- Like `%x' but the locale's alternative data representation is -- used. -- -- `%X' -- The time using the locale's time format. -- -- `%EX' -- Like `%X' but the locale's alternative time representation is -- 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; -- } -- -- --File: libc.info, Node: General Time String Parsing, Prev: Low-Level Time String Parsing, Up: Parsing Date and Time -- --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 -- Feb 10:30 %b %H:%S Sun Feb 1 10:00:30 EST 1987 -- 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.

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'.

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. -- -- --File: libc.info, Node: Time Zone Functions, Next: Time Functions Example, Prev: TZ Variable, Up: Calendar Time -- --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.

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. -- -- --File: libc.info, Node: Sleeping, Prev: Setting an Alarm, Up: Date and Time -- --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'. -- -- --File: libc.info, Node: Resource Usage And Limitation, Next: Non-Local Exits, Prev: Date and Time, Up: Top -- --Resource Usage And Limitation --***************************** -- -- This chapter describes functions for examining how much of various --kinds of resources (CPU time, memory, etc.) a process has used and --getting and setting limits on future usage. -- --* Menu: -- --* Resource Usage:: Measuring various resources used. --* Limits on Resources:: Specifying limits on resource usage. --* Priority:: Reading or setting process run priority. --* Memory Resources:: Querying memory available resources. --* Processor Resources:: Learn about the processors available. -- -- --File: libc.info, Node: Resource Usage, Next: Limits on Resources, Up: Resource Usage And Limitation -- --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' -- -- `vm_ixrss' -- Shared memory.

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 --`sys/vtimes.h'. -- -- --File: libc.info, Node: Limits on Resources, Next: Priority, Prev: Resource Usage, Up: Resource Usage And Limitation -- --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_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. -- -- -- --File: libc.info, Node: Priority, Next: Memory Resources, Prev: Limits on Resources, Up: Resource Usage And Limitation -- --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. -- --* Menu: -- --* Absolute Priority:: The first tier of priority. Posix --* Realtime Scheduling:: Scheduling among the process nobility --* Basic Scheduling Functions:: Get/set scheduling policy, priority --* Traditional Scheduling:: Scheduling among the vulgar masses -- -- --File: libc.info, Node: Absolute Priority, Next: Realtime Scheduling, Up: Priority -- --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. -- -- --File: libc.info, Node: Realtime Scheduling, Next: Basic Scheduling Functions, Prev: Absolute Priority, Up: Priority -- --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.

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.

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::. -- -diff -u -udbrN glibc-2.3.2/manual/libc.info-38 glibc-2.3.2-200304020432/manual/libc.info-38 ---- glibc-2.3.2/manual/libc.info-38 Sat Mar 1 02:39:41 2003 -+++ glibc-2.3.2-200304020432/manual/libc.info-38 Thu Jan 1 01:00:00 1970 -@@ -1,1105 +0,0 @@ --This is libc.info, produced by makeinfo version 4.2 from libc.texinfo. -- --INFO-DIR-SECTION GNU libraries --START-INFO-DIR-ENTRY --* Libc: (libc).

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. -- -- --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'.

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 -- #include -- #include -- -- 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. */ -- ... -- -- --File: libc.info, Node: Non-Local Details, Next: Non-Local Exits and Signals, Prev: Non-Local Intro, Up: Non-Local Exits -- --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'. -- -- --File: libc.info, Node: Non-Local Exits and Signals, Next: System V contexts, Prev: Non-Local Details, Up: Non-Local Exits -- --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::.

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'.

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. -- -- #include -- #include -- #include -- #include -- #include -- -- /* Set by the signal handler. */ -- static volatile int expired; -- -- /* The contexts. */ -- static ucontext_t uc[3]; -- -- /* We do only a certain number of switches. */ -- static int switches; -- -- -- /* This is the function doing the work.

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'.

The various --kinds of signals are listed and described in detail in *Note Standard --Signals::. -- -- --File: libc.info, Node: Signal Generation, Next: Delivery of Signal, Prev: Kinds of Signals, Up: Concepts of 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 --can be generated synchronously or asynchronously with an explicit --request. -- -- --File: libc.info, Node: Delivery of Signal, Prev: Signal Generation, Up: Concepts of Signals -- --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. -- -- --File: libc.info, Node: Standard Signals, Next: Signal Actions, Prev: Concepts of Signals, Up: Signal Handling -- --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.

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.

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. -- -- --File: libc.info, Node: Termination Signals, Next: Alarm Signals, Prev: Program Error Signals, Up: Standard Signals -- --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::. -- -- --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. -- -- --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. -- -- --File: libc.info, Node: Operation Error Signals, Next: Miscellaneous Signals, Prev: Job Control Signals, Up: Standard Signals -- --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::. -- -- --File: libc.info, Node: Miscellaneous Signals, Next: Signal Messages, Prev: Operation Error Signals, Up: Standard Signals -- --Miscellaneous Signals ----------------------- -- -- 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. -- -- --File: libc.info, Node: Signal Messages, Prev: Miscellaneous Signals, Up: Standard Signals -- --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'. -- -- --File: libc.info, Node: Signal Actions, Next: Defining Handlers, Prev: Standard Signals, Up: Signal Handling -- --Specifying Signal Actions --========================= -- -- The simplest way to change the action for a signal is to use the --`signal' function. You can specify a built-in action (such as to --ignore the signal), or you can "establish a handler". -- -- The GNU library also implements the more versatile `sigaction' --facility. This section describes both facilities and gives suggestions --on which to use when. -- --* Menu: -- --* Basic Signal Handling:: The simple `signal' function. --* Advanced Signal Handling:: The more powerful `sigaction' function. --* Signal and Sigaction:: How those two functions interact. --* Sigaction Function Example:: An example of using the sigaction function. --* Flags for Sigaction:: Specifying options for signal handling. --* Initial Signal Actions:: How programs inherit signal actions. -- -- --File: libc.info, Node: Basic Signal Handling, Next: Advanced Signal Handling, Up: Signal Actions -- --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 -- -- 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. -- -- --File: libc.info, Node: Advanced Signal Handling, Next: Signal and Sigaction, Prev: Basic Signal Handling, Up: Signal Actions -- --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'. -- -- --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. -- -- --File: libc.info, Node: Sigaction Function Example, Next: Flags for Sigaction, Prev: Signal and Sigaction, Up: Signal Actions -- --`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 -- -- 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.

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::.

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.

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 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. -- -- --File: libc.info, Node: Hooks for Malloc, Next: Statistics of Malloc, Prev: Heap Consistency Checking, Up: Unconstrained Allocation -- --Memory Allocation Hooks --....................... -- -- The GNU C library lets you modify the behavior of `malloc', --`realloc', and `free' by specifying appropriate hook functions.

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 -- -- 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.

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".

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. -- -- --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 -- -- 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.

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. -- -- --File: libc.info, Node: Merged Signals, Next: Nonreentrancy, Prev: Signals in Handler, Up: Defining Handlers -- --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.

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. -- -- --File: libc.info, Node: Atomic Data Access, Prev: Nonreentrancy, Up: Defining Handlers -- --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".

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. -- -- --File: libc.info, Node: Interrupted Primitives, Next: Generating Signals, Prev: Defining Handlers, Up: Signal Handling -- --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.

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.

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'. -- --* Menu: -- --* Argument Syntax:: By convention, options start with a hyphen. --* Parsing Program Arguments:: Ways to parse program options and arguments. -- -- --File: libc.info, Node: Argument Syntax, Next: Parsing Program Arguments, Up: Program Arguments -- --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. -- -- --File: libc.info, Node: Parsing Program Arguments, Prev: Argument Syntax, Up: Program Arguments -- --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. -- --* Menu: -- --* Getopt:: Parsing program options using `getopt'. --* Argp:: Parsing program options using `argp_parse'. --* Suboptions:: Some programs need more detailed options. --* Suboptions Example:: This shows how it could be done for `mount'. -- -- --File: libc.info, Node: Getopt, Next: Argp, Up: Parsing Program Arguments -- --Parsing program options using `getopt' --====================================== -- -- The `getopt' and `getopt_long' functions automate some of the chore --involved in parsing typical unix command line options. -- --* Menu: -- --* Using Getopt:: Using the `getopt' function. --* Example of Getopt:: An example of parsing options with `getopt'. --* Getopt Long Options:: GNU suggests utilities accept long-named -- options; here is one way to do. --* Getopt Long Option Example:: An example of using `getopt_long'. -- -- --File: libc.info, Node: Using Getopt, Next: Example of Getopt, Up: Getopt -- --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. -- -- --File: libc.info, Node: Example of Getopt, Next: Getopt Long Options, Prev: Using Getopt, Up: Getopt -- --Example of Parsing Arguments with `getopt' -------------------------------------------- -- -- Here is an example showing how `getopt' is typically used.

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 `--'.

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.

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.

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.

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'.

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.

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::. -- -- --File: libc.info, Node: Standard Environment, Prev: Environment Access, Up: Environment Variables -- --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 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 -- #include -- #include -- -- ... -- -- 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 -- #include -- #include -- -- ... -- -- int rc; -- -- rc = chmod("/etc/passwd", 0444); -- if (rc == -1) -- fprintf(stderr, "chmod failed, errno = %d\n", errno); -- -- -- --File: libc.info, Node: Program Termination, Prev: System Calls, Up: Program Basics -- --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::.

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. -- -- --File: libc.info, Node: Cleanups on Exit, Next: Aborting a Program, Prev: Exit Status, Up: Program Termination -- --Cleanups on Exit ------------------ -- -- Your program can arrange to run its own cleanup functions if normal --termination happens.

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. -- -- --File: libc.info, Node: Process Identification, Next: Creating a Process, Prev: Process Creation Concepts, Up: Processes -- --Process Identification --====================== -- -- The `pid_t' data type represents process IDs.

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.

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.

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).

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. -- -- *Note Access to the Terminal::, for more information about I/O to the --controlling terminal, -- -- --File: libc.info, Node: Job Control is Optional, Next: Controlling Terminal, Prev: Concepts of Job Control, Up: Job Control -- --Job Control is Optional --======================= -- -- Not all operating systems support job control.

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::. -- -- --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. -- -- --File: libc.info, Node: Implementing a Shell, Next: Functions for Job Control, Prev: Orphaned Process Groups, Up: Job Control -- --Implementing a Job Control Shell --================================ -- -- This section describes what a shell must do to implement job --control, by presenting an extensive sample program to illustrate the --concepts involved. -- --* Menu: -- --* Data Structures:: Introduction to the sample shell. --* Initializing the Shell:: What the shell must do to take -- responsibility for job control. --* Launching Jobs:: Creating jobs to execute commands. --* Foreground and Background:: Putting a job in foreground of background. --* Stopped and Terminated Jobs:: Reporting job status. --* Continuing Stopped Jobs:: How to continue a stopped job in -- the foreground or background. --* Missing Pieces:: Other parts of the shell. -- -- --File: libc.info, Node: Data Structures, Next: Initializing the Shell, Up: Implementing a Shell -- --Data Structures for the Shell ------------------------------- -- -- All of the program examples included in this chapter are part of a --simple shell program.

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 -- #include -- #include -- -- pid_t shell_pgid; -- struct termios shell_tmodes; -- int shell_terminal; -- int shell_is_interactive; -- -- -- /* Make sure the shell is running interactively as the foreground job -- before proceeding. */ -- -- void -- init_shell () -- { -- -- /* See if we are running interactively. */ -- shell_terminal = STDIN_FILENO; -- shell_is_interactive = isatty (shell_terminal); -- -- if (shell_is_interactive) -- { -- /* Loop until we are in the foreground. */ -- while (tcgetpgrp (shell_terminal) != (shell_pgid = getpgrp ())) -- kill (- shell_pgid, SIGTTIN); -- -- /* Ignore interactive and job-control signals. */ -- signal (SIGINT, SIG_IGN); -- signal (SIGQUIT, SIG_IGN); -- signal (SIGTSTP, SIG_IGN); -- signal (SIGTTIN, SIG_IGN); -- signal (SIGTTOU, SIG_IGN); -- signal (SIGCHLD, SIG_IGN); -- -- /* Put ourselves in our own process group. */ -- shell_pgid = getpid (); -- if (setpgid (shell_pgid, shell_pgid) < 0) -- { -- perror ("Couldn't put the shell in its own process group"); -- exit (1); -- } -- -- /* Grab control of the terminal. */ -- tcsetpgrp (shell_terminal, shell_pgid); -- -- /* Save default terminal attributes for shell. */ -- tcgetattr (shell_terminal, &shell_tmodes); -- } -- } -- -- --File: libc.info, Node: Launching Jobs, Next: Foreground and Background, Prev: Initializing the Shell, Up: Implementing a Shell -- --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.

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). -- -- --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. -- -- --File: libc.info, Node: NSS Module Internals, Next: Extending NSS, Prev: NSS Configuration File, Up: Name Service Switch -- --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. -- --* Menu: -- --* NSS Module Names:: Construction of the interface function of -- the NSS modules. --* NSS Modules Interface:: Programming interface in the NSS module -- functions. -- -- --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. -- -- --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. -- -- --File: libc.info, Node: Extending NSS, Prev: NSS Module Internals, Up: Name Service Switch -- --Extending NSS --============= -- -- One of the advantages of NSS mentioned above is that it can be --extended quite easily.

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.

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::). -- -- --File: libc.info, Node: Users and Groups, Next: System Management, Prev: Name Service Switch, Up: Top -- --Users and Groups --**************** -- -- Every user who can log in on the system is identified by a unique --number called the "user ID".

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. -- -- --File: libc.info, Node: Why Change Persona, Next: How Change Persona, Prev: Process Persona, Up: Users and Groups -- --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.

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.

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.

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'.

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. -- -- --File: libc.info, Node: Who Logged In, Next: User Accounting Database, Prev: Tips for Setuid, Up: Users and Groups -- --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.

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.

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.

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 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 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. -- -- --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.

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. -- -- --File: libc.info, Node: Platform Type, Next: Filesystem Handling, Prev: Host Identification, Up: System Management -- --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.

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" --filesystem, for example, contains files whose data is made up by the --filesystem driver on the fly whenever you ask for it. And when you --write to it, the data you write causes changes in the system. No data --gets stored. -- --* Menu: -- --* Mount Information:: What is or could be mounted? --* Mount-Unmount-Remount:: Controlling what is mounted and how -- -- --File: libc.info, Node: Mount Information, Next: Mount-Unmount-Remount, Up: Filesystem Handling -- --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. -- --* Menu: -- --* fstab:: The `fstab' file --* mtab:: The `mtab' file --* Other Mount Information:: Other (non-libc) sources of mount information -- -- --File: libc.info, Node: fstab, Next: mtab, Up: Mount Information -- --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.

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"'.

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. -- -- --File: libc.info, Node: Other Mount Information, Prev: mtab, Up: Mount Information -- --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.

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 -- -- 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 -- -- 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. -- -- `EINVAL' -- FILE validly refers to a file, but that file is neither a -- mount point nor a device special file of a currently mounted -- filesystem. -- -- This function is not available on all systems. -- -- - Function: int umount (const char *FILE) -- `umount' does the same thing as `umount2' with FLAGS set to -- zeroes. It is more widely available than `umount2' but since it -- lacks the possibility to forcefully unmount a filesystem is -- deprecated when `umount2' is also available. -- -- --File: libc.info, Node: System Parameters, Prev: Filesystem Handling, Up: System Management -- --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' -- -- --File: libc.info, Node: System Configuration, Next: Cryptographic Functions, Prev: System Management, Up: Top -- --System Configuration Parameters --******************************* -- -- The functions and macros listed in this chapter give information --about configuration parameters of the operating system--for example, --capacity limits, presence of optional POSIX features, and the default --path for executable files (*note String Parameters::). -- --* Menu: -- --* General Limits:: Constants and functions that describe -- various process-related limits that have -- one uniform value for any given machine. --* System Options:: Optional POSIX features. --* Version Supported:: Version numbers of POSIX.1 and POSIX.2. --* Sysconf:: Getting specific configuration values -- of general limits and system options. --* Minimums:: Minimum values for general limits. -- --* Limits for Files:: Size limitations that pertain to individual files. -- These can vary between file systems -- or even from file to file. --* Options for Files:: Optional features that some files may support. --* File Minimums:: Minimum values for file limits. --* Pathconf:: Getting the limit values for a particular file. -- --* Utility Limits:: Capacity limits of some POSIX.2 utility programs. --* Utility Minimums:: Minimum allowable values of those limits. -- --* String Parameters:: Getting the default search path. -- -- --File: libc.info, Node: General Limits, Next: System Options, Up: System Configuration -- --General Capacity Limits --======================= -- -- The POSIX.1 and POSIX.2 standards specify a number of parameters that --describe capacity limitations of the system.

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 -- #include -- -- 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. -- -- --File: libc.info, Node: crypt, Next: DES Encryption, Prev: getpass, Up: Cryptographic Functions -- --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 -- #include -- #include -- #include -- -- int -- main(void) -- { -- unsigned long seed[2]; -- char salt[] = "$1$........"; -- const char *const seedchars = -- "./0123456789ABCDEFGHIJKLMNOPQRST" -- "UVWXYZabcdefghijklmnopqrstuvwxyz"; -- char *password; -- int i; -- -- /* Generate a (not very) random seed. -- You should do it better than this... */ -- seed[0] = time(NULL); -- seed[1] = getpid() ^ (seed[0] >> 14 & 0x30000); -- -- /* Turn it into printable characters from `seedchars'. */ -- for (i = 0; i < 8; i++) -- salt[3+i] = seedchars[(seed[i/5] >> (i%5)*6) & 0x3f]; -- -- /* Read in the user's password and encrypt it. */ -- password = crypt(getpass("Password:"), salt); -- -- /* Print the results. */ -- puts(password); -- return 0; -- } -- -- The next program shows how to verify a password.

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'. -- -- --File: libc.info, Node: Debugging Support, Next: POSIX Threads, Prev: Cryptographic Functions, Up: Top -- --Debugging support --***************** -- -- 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.

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).

With this technique, you do not --need to know how much data you will put in the object until you come to --the end of it. We call this the technique of "growing objects". The --special functions for adding data to the growing object are described --in this section. -- -- 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.

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'.

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. -- -- --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.

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').

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'.

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.

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.

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. -- -- --File: libc.info, Node: Streams and Fork, Next: Miscellaneous Thread Functions, Prev: Threads and Fork, Up: POSIX Threads -- --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. -- -- --File: libc.info, Node: Miscellaneous Thread Functions, Prev: Streams and Fork, Up: POSIX Threads -- --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.

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.

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!). -- -- --File: libc.info, Node: How Variadic, Next: Variadic Example, Prev: Why Variadic, Up: Variadic Functions -- --How Variadic Functions are Defined and Used --------------------------------------------- -- -- Defining and using a variadic function involves three steps: -- -- * _Define_ the function as variadic, using an ellipsis (`...') in -- the argument list, and using special macros to access the variable -- arguments. *Note Receiving Arguments::. -- -- * _Declare_ the function as variadic, using a prototype with an -- ellipsis (`...'), in all the files which call it. *Note Variadic -- Prototypes::. -- -- * _Call_ the function by writing the fixed arguments followed by the -- additional variable arguments. *Note Calling Variadics::. -- --* Menu: -- --* Variadic Prototypes:: How to make a prototype for a function -- with variable arguments. --* Receiving Arguments:: Steps you must follow to access the -- optional argument values. --* How Many Arguments:: How to decide whether there are more arguments. --* Calling Variadics:: Things you need to know about calling -- variable arguments functions. --* Argument Macros:: Detailed specification of the macros -- for accessing variable arguments. --* Old Varargs:: The pre-ISO way of defining variadic functions. -- -- --File: libc.info, Node: Variadic Prototypes, Next: Receiving Arguments, Up: How Variadic -- --Syntax for Variable Arguments --............................. -- -- A function that accepts a variable number of arguments must be --declared with a prototype that says so.

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'.

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.

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. -- -- --File: libc.info, Node: How Many Arguments, Next: Calling Variadics, Prev: Receiving Arguments, Up: How Variadic -- --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.

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. -- -- --File: libc.info, Node: Argument Macros, Next: Old Varargs, Prev: Calling Variadics, Up: How Variadic -- --Argument Access Macros --...................... -- -- Here are descriptions of the macros used to retrieve variable --arguments.

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'.) -- -- --File: libc.info, Node: Floating Point Parameters, Next: IEEE Floating Point, Prev: Floating Point Concepts, Up: Floating Type Macros -- --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.

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.

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. -- -- --File: libc.info, Node: Running make install, Next: Tools for Compilation, Prev: Configuring and compiling, Up: Installation -- --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'. -- -- --File: libc.info, Node: Tools for Compilation, Next: Supported Configurations, Prev: Running make install, Up: Installation -- --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. -- -- --File: libc.info, Node: Supported Configurations, Next: Linux, Prev: Tools for Compilation, Up: Installation -- --Supported Configurations --======================== -- -- The GNU C Library currently supports configurations that match the --following patterns: -- -- alpha*-*-linux -- arm-*-linux -- cris-*-linux -- hppa-*-linux -- iX86-*-gnu -- iX86-*-linux -- ia64-*-linux -- m68k-*-linux -- mips*-*-linux -- powerpc-*-linux -- s390-*-linux -- s390x-*-linux -- sparc-*-linux -- sparc64-*-linux -- -- Former releases of this library (version 2.1 and/or 2.0) used to run --on the following configurations: -- -- arm-*-linuxaout -- arm-*-none -- -- Very early releases (version 1.09.1 and perhaps earlier versions) --used to run on the following configurations: -- -- alpha-dec-osf1 -- alpha-*-linuxecoff -- iX86-*-bsd4.3 -- iX86-*-isc2.2 -- iX86-*-isc3.N -- iX86-*-sco3.2 -- iX86-*-sco3.2v4 -- iX86-*-sysv -- iX86-*-sysv4 -- iX86-force_cpu386-none -- iX86-sequent-bsd -- i960-nindy960-none -- m68k-hp-bsd4.3 -- m68k-mvme135-none -- m68k-mvme136-none -- m68k-sony-newsos3 -- m68k-sony-newsos4 -- m68k-sun-sunos4.N -- mips-dec-ultrix4.N -- mips-sgi-irix4.N -- sparc-sun-solaris2.N -- sparc-sun-sunos4.N -- -- Since no one has volunteered to test and fix these configurations, --they are not supported at the moment. They probably don't compile; --they definitely 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 . -- -- 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. -- -- --File: libc.info, Node: Linux, Next: Reporting Bugs, Prev: Supported Configurations, Up: Installation -- --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 -- 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. -- -- --File: libc.info, Node: Reporting Bugs, Prev: Linux, Up: Installation -- --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 . 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 . 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!

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'. -- -- --File: libc.info, Node: Porting, Prev: Source Layout, Up: Maintenance -- --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 --`' into your file. This causes the function to be listed --in the installed `', 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. -- --* Menu: -- --* Hierarchy Conventions:: The layout of the `sysdeps' hierarchy. --* Porting to Unix:: Porting the library to an average -- Unix-like system. -- -- --File: libc.info, Node: Hierarchy Conventions, Next: Porting to Unix, Up: Porting -- --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 -- linuxthreads/sysdeps/i386/i686 -- linuxthreads/sysdeps/i386 -- linuxthreads/sysdeps/pthread/no-cmpxchg -- sysdeps/unix/sysv/linux/i386 -- sysdeps/unix/sysv/linux -- sysdeps/gnu -- sysdeps/unix/common -- sysdeps/unix/mman -- sysdeps/unix/inet -- sysdeps/unix/sysv/i386/i686 -- sysdeps/unix/sysv/i386 -- sysdeps/unix/sysv -- sysdeps/unix/i386 -- sysdeps/unix -- sysdeps/posix -- sysdeps/i386/i686 -- sysdeps/i386/i486 -- sysdeps/libm-i387/i686 -- sysdeps/i386/fpu -- 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.

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'. -- -- --File: libc.info, Node: Porting to Unix, Prev: Hierarchy Conventions, Up: Porting -- --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.

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.

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.

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.

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 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. -- -- --File: libc.info, Node: Wide Character Case Conversion, Prev: Using Wide Char Classes, Up: Character Handling -- --Mapping of wide characters. --=========================== -- -- The classification functions are also generalized by the ISO C --standard.

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. -- -- --File: libc.info, Node: String/Array Conventions, Next: String Length, Prev: Representation of Strings, Up: String and Array Utilities -- --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. -- -- --File: libc.info, Node: String Length, Next: Copying and Concatenation, Prev: String/Array Conventions, Up: String and Array Utilities -- --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 `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.

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.

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 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.

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::).

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.

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.

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.

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.

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.

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.

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.

It returns a pointer -- to the next element in ARGZ after the element ENTRY, or `0' if -- there are no elements following ENTRY.

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. -- -- --File: libc.info, Node: Charset Function Overview, Next: Restartable multibyte conversion, Prev: Extended Char Intro, Up: Character Set Handling -- --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. -- -- --File: libc.info, Node: Restartable multibyte conversion, Next: Non-reentrant Conversion, Prev: Charset Function Overview, Up: Character Set Handling -- --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::). -- --* Menu: -- --* Selecting the Conversion:: Selecting the conversion and its properties. --* Keeping the state:: Representing the state of the conversion. --* Converting a Character:: Converting Single Characters. --* Converting Strings:: Converting Multibyte and Wide Character -- Strings. --* Multibyte Conversion Example:: A Complete Multibyte Conversion Example. -- -- --File: libc.info, Node: Selecting the Conversion, Next: Keeping the state, Up: Restartable multibyte 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. -- -- --File: libc.info, Node: Keeping the state, Next: Converting a Character, Prev: Selecting the Conversion, Up: Restartable multibyte conversion -- --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. -- -- --File: libc.info, Node: Converting a Character, Next: Converting Strings, Prev: Keeping the state, Up: Restartable multibyte conversion -- --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. -- -- --File: libc.info, Node: Converting Strings, Next: Multibyte Conversion Example, Prev: Converting a Character, Up: Restartable multibyte conversion -- --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. -- -diff -u -udbrN glibc-2.3.2/manual/libc.pg glibc-2.3.2-200304020432/manual/libc.pg ---- glibc-2.3.2/manual/libc.pg Tue
