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/semaphore.h | 10 ++++++++-- 1 file changed, 8 insertions(+), 2 deletions(-) (limited to 'include/semaphore.h') diff --git a/include/semaphore.h b/include/semaphore.h index 2e9b8100..724957fb 100644 --- a/include/semaphore.h +++ b/include/semaphore.h @@ -4,6 +4,12 @@ extern "C" { #endif +#if __STDC_VERSION__ >= 199901L +#define __restrict restrict +#elif !defined(__GNUC__) +#define __restrict +#endif + #define __NEED_time_t #define __NEED_struct_timespec #include @@ -18,11 +24,11 @@ typedef struct { int sem_close(sem_t *); int sem_destroy(sem_t *); -int sem_getvalue(sem_t *, int *); +int sem_getvalue(sem_t *__restrict, int *__restrict); int sem_init(sem_t *, int, unsigned); sem_t *sem_open(const char *, int, ...); int sem_post(sem_t *); -int sem_timedwait(sem_t *, const struct timespec *); +int sem_timedwait(sem_t *__restrict, const struct timespec *__restrict); int sem_trywait(sem_t *); int sem_unlink(const char *); int sem_wait(sem_t *); -- cgit v1.2.1
