From ed952e89a6a10560d4e65fc508ab47fbb63dd60f Mon Sep 17 00:00:00 2001 From: Manuel Novoa III Date: Sat, 30 Jul 2005 01:02:57 +0000 Subject: sjhill appears confused. vapier's earlier commit of string.h was broken. But I fixed it, and tested both x86 (locale) and mipsel before I commited the fixes. Just built with gcc 4.0.1 to see if that was the cause of his problems, but x86 (locale) built fine. So revert his last change. --- include/string.h | 61 +++++++++++++++++++++++++++++++++----------------------- 1 file changed, 36 insertions(+), 25 deletions(-) (limited to 'include') diff --git a/include/string.h b/include/string.h index 59f0ac481..224bb8621 100644 --- a/include/string.h +++ b/include/string.h @@ -122,13 +122,13 @@ __END_NAMESPACE_STD extern int strcoll_l (__const char *__s1, __const char *__s2, __locale_t __l) __THROW __attribute_pure__ __nonnull ((1, 2, 3)); extern int __strcoll_l (__const char *__s1, __const char *__s2, __locale_t __l) - __THROW __attribute_pure__; + __THROW __attribute_pure__ __nonnull ((1, 2, 3)); /* Put a transformation of SRC into no more than N bytes of DEST. */ extern size_t strxfrm_l (char *__dest, __const char *__src, size_t __n, __locale_t __l) __THROW __nonnull ((2, 4)); extern size_t __strxfrm_l (char *__dest, __const char *__src, size_t __n, - __locale_t __l) __THROW; + __locale_t __l) __THROW __nonnull ((2, 4)); #endif #endif /* __UCLIBC_HAS_XLOCALE__ */ @@ -263,33 +263,41 @@ __BEGIN_NAMESPACE_STD /* Return a string describing the meaning of the `errno' code in ERRNUM. */ extern char *strerror (int __errnum) __THROW; __END_NAMESPACE_STD + +extern char *__glibc_strerror_r (int __errnum, char *__buf, size_t __buflen) + __THROW __nonnull ((2)); +extern int __xpg_strerror_r (int __errnum, char *__buf, size_t __buflen) + __THROW __nonnull ((2)); + #if defined __USE_XOPEN2K || defined __USE_MISC -/* Reentrant version of `strerror'.
