From 74823419761c11830ea1819365f82cf3d48795cb Mon Sep 17 00:00:00 2001 From: Josh Triplett Date: Tue, 20 Aug 2013 17:20:15 -0700 Subject: [PATCH] turbostat: Check return value of fscanf Some systems declare fscanf with the warn_unused_result attribute. On such systems, turbostat generates the following warnings: turbostat.c: In function 'get_core_id': turbostat.c:1203:8: warning: ignoring return value of 'fscanf', declared with attribute warn_unused_result [-Wunused-result] turbostat.c: In function 'get_physical_package_id': turbostat.c:1186:8: warning: ignoring return value of 'fscanf', declared with attribute warn_unused_result [-Wunused-result] turbostat.c: In function 'cpu_is_first_core_in_package': turbostat.c:1169:8: warning: ignoring return value of 'fscanf', declared with attribute warn_unused_result [-Wunused-result] turbostat.c: In function 'cpu_is_first_sibling_in_core': turbostat.c:1148:8: warning: ignoring return value of 'fscanf', declared with attribute warn_unused_result [-Wunused-result] Fix these by checking the return value of those four calls to fscanf.
