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/dlfcn.h | 8 +++++++- 1 file changed, 7 insertions(+), 1 deletion(-) (limited to 'include/dlfcn.h') diff --git a/include/dlfcn.h b/include/dlfcn.h index e98c8ca6..2e7d0283 100644 --- a/include/dlfcn.h +++ b/include/dlfcn.h @@ -5,6 +5,12 @@ extern "C" { #endif +#if __STDC_VERSION__ >= 199901L +#define __restrict restrict +#elif !defined(__GNUC__) +#define __restrict +#endif + #define RTLD_LAZY 1 #define RTLD_NOW 2 #define RTLD_GLOBAL 256 @@ -16,7 +22,7 @@ extern "C" { int dlclose(void *); char *dlerror(void); void *dlopen(const char *, int); -void *dlsym(void *, const char *); +void *dlsym(void *__restrict, const char *__restrict); #ifdef _GNU_SOURCE typedef struct { -- cgit v1.2.1
