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/search.h | 9 ++++++++- 1 file changed, 8 insertions(+), 1 deletion(-) (limited to 'include/search.h') diff --git a/include/search.h b/include/search.h index 7c4fc583..680eee75 100644 --- a/include/search.h +++ b/include/search.h @@ -5,6 +5,13 @@ extern "C" { #endif +#if __STDC_VERSION__ >= 199901L +#define __restrict restrict +#elif !defined(__GNUC__) +#define __restrict +#endif + + #define __NEED_size_t #include @@ -28,7 +35,7 @@ void *lsearch(const void *, void *, size_t *, size_t, void *lfind(const void *, const void *, size_t *, size_t, int (*)(const void *, const void *)); -void *tdelete(const void *, void **, int(*)(const void *, const void *)); +void *tdelete(const void *__restrict, void **__restrict, int(*)(const void *, const void *)); void *tfind(const void *, void *const *, int(*)(const void *, const void *)); void *tsearch(const void *, void **, int (*)(const void *, const void *)); void twalk(const void *, void (*)(const void *, VISIT, int)); -- cgit v1.2.1
