From 400c5e5c8307a2ebe44ef1f203f5a15669f20347 Mon Sep 17 00:00:00 2001 From: Rich Felker Date: Thu, 6 Sep 2012 22:44:55 -0400 Subject: use restrict everywhere it's required by c99 and/or posix 2008 to deal with the fact that the public headers may be used with pre-c99 compilers, __restrict is used in place of restrict, and defined appropriately for any supported compiler. we also avoid the form [restrict] since older versions of gcc rejected it due to a bug in the original c99 standard, and instead use the form *restrict. --- include/sys/time.h | 10 ++++++++-- 1 file changed, 8 insertions(+), 2 deletions(-) (limited to 'include/sys/time.h') diff --git a/include/sys/time.h b/include/sys/time.h index 144dd230..bf026432 100644 --- a/include/sys/time.h +++ b/include/sys/time.h @@ -4,9 +4,15 @@ extern "C" { #endif +#if __STDC_VERSION__ >= 199901L +#define __restrict restrict +#elif !defined(__GNUC__) +#define __restrict +#endif + #include -int gettimeofday (struct timeval *, void *); +int gettimeofday (struct timeval *__restrict, void *__restrict); #if defined(_XOPEN_SOURCE) || defined(_GNU_SOURCE) \ || defined(_BSD_SOURCE) @@ -22,7 +28,7 @@ struct itimerval }; int getitimer (int, struct itimerval *); -int setitimer (int, const struct itimerval *, struct itimerval *); +int setitimer (int, const struct itimerval *__restrict, struct itimerval *__restrict); int utimes (const char *, const struct timeval [2]); #endif -- cgit v1.2.1
