From 769fd4ce202225ba1f2621bbefb803ee9a268ebf Mon Sep 17 00:00:00 2001 From: Rich Felker Date: Mon, 3 Dec 2012 16:57:01 -0500 Subject: feature test macros: make _GNU_SOURCE enable everything previously, a few BSD features were enabled only by _BSD_SOURCE, not by _GNU_SOURCE. since _BSD_SOURCE is default in the absence of other feature test macros, this made adding _GNU_SOURCE to a project not a purely additive feature test macro; it actually caused some features to be suppressed. most of the changes made by this patch actually bring musl in closer alignment with the glibc behavior for _GNU_SOURCE. the only exceptions are the added visibility of functions like strlcpy which were BSD-only due to being disliked/rejected by glibc maintainers. here, I feel the consistency of having _GNU_SOURCE mean "everything", and especially the property of it being purely additive, are more valuable than hiding functions which glibc does not have. --- include/string.h | 3 --- 1 file changed, 3 deletions(-) (limited to 'include/string.h') diff --git a/include/string.h b/include/string.h index 33f01378..c2f8eb55 100644 --- a/include/string.h +++ b/include/string.h @@ -81,9 +81,6 @@ void *memccpy (void *__restrict, const void *__restrict, int, size_t); #if defined(_GNU_SOURCE) || defined(_BSD_SOURCE) char *strsep(char **, const char *); -#endif - -#ifdef _BSD_SOURCE size_t strlcat (char *, const char *, size_t); size_t strlcpy (char *, const char *, size_t); #endif -- cgit v1.2.1
