(mq_open): New strong_alias. (__mq_open_2): New function. * sysdeps/unix/sysv/linux/mq_open.c (__mq_open): Renamed from mq_open. (mq_open): New strong_alias. (__mq_open_2): New function. * debug/Versions (libc): Export __fortify_fail@@GLIBC_PRIVATE. * Versions.def (librt): Add GLIBC_2.7 version. * debug/fortify_fail.c (__fortify_fail): Add libc_hidden_def. * include/stdio.h (__fortify_fail): Add libc_hidden_proto. * misc/sys/cdefs.h (__errordecl, __va_arg_pack_len): Define. * io/fcntl.h: Include bits/fcntl2.h when __va_arg_pack_len is defined rather than when not C++. * io/bits/fcntl2.h (__open_alias, __open64_alias, __openat_alias, __openat64_alias): New redirects.

(open, open64, openat, openat64): Rewrite as __extern_always_inline functions instead of function-like macros. --- sysdeps/unix/sysv/linux/mq_open.c | 14 ++++++++++++-- 1 file changed, 12 insertions(+), 2 deletions(-) (limited to 'sysdeps/unix/sysv/linux/mq_open.c') diff --git a/sysdeps/unix/sysv/linux/mq_open.c b/sysdeps/unix/sysv/linux/mq_open.c index eac6e01238..6330fee4e7 100644 --- a/sysdeps/unix/sysv/linux/mq_open.c +++ b/sysdeps/unix/sysv/linux/mq_open.c @@ -1,4 +1,4 @@ -/* Copyright (C) 2004, 2005 Free Software Foundation, Inc. +/* Copyright (C) 2004, 2005, 2007 Free Software Foundation, Inc.
