From a8c2fa984a42b43be06898a09a59a660131f91cd Mon Sep 17 00:00:00 2001 From: Joseph Myers Date: Tue, 13 Aug 2019 11:27:06 +0000 Subject: Declare memccpy, strdup, strndup for C2X. C2X adds the memccpy, strdup and strndup functions. This patch duly adds __GLIBC_USE (ISOC2X) to the conditions under which declares them. Tested for x86_64. * string/string.h (memccpy): Also declare if [__GLIBC_USE (ISOC2X)]. (strdup): Likewise. (strndup): Likewise. --- string/string.h | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) (limited to 'string/string.h') diff --git a/string/string.h b/string/string.h index c38eea971f..f51a9e2270 100644 --- a/string/string.h +++ b/string/string.h @@ -49,7 +49,7 @@ extern void *memmove (void *__dest, const void *__src, size_t __n) /* Copy no more than N bytes of SRC to DEST, stopping when C is found.
