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/dirent.h | 8 +++++++- 1 file changed, 7 insertions(+), 1 deletion(-) (limited to 'include/dirent.h') diff --git a/include/dirent.h b/include/dirent.h index c19f7d58..b6261595 100644 --- a/include/dirent.h +++ b/include/dirent.h @@ -5,6 +5,12 @@ extern "C" { #endif +#if __STDC_VERSION__ >= 199901L +#define __restrict restrict +#elif !defined(__GNUC__) +#define __restrict +#endif + #define __NEED_ino_t #define __NEED_off_t #ifdef _BSD_SOURCE @@ -30,7 +36,7 @@ int closedir(DIR *); DIR *fdopendir(int); DIR *opendir(const char *); struct dirent *readdir(DIR *); -int readdir_r(DIR *, struct dirent *, struct dirent **); +int readdir_r(DIR *__restrict, struct dirent *__restrict, struct dirent **__restrict); void rewinddir(DIR *); void seekdir(DIR *, long); long telldir(DIR *); -- cgit v1.2.1
