From 28cb9295720d06156b7c6b577086b199a47902d3 Mon Sep 17 00:00:00 2001 From: Roland McGrath Date: Fri, 24 Aug 2001 03:20:56 +0000 Subject: [PATCH] 2001-08-23 Roland McGrath * sysdeps/generic/bits/stdio-lock.h (_IO_lock_initializer): Define to _LIBC_LOCK_RECURSIVE_INITIALIZER if defined, else do an #error. (__libc_cleanup_region_start, __libc_cleanup_region_end, __libc_clean_end): Define these to call the cleanup function after normal exit when they're supposed to. * sysdeps/mach/bits/libc-lock.h (__libc_cleanup_region_start): Take new first arg DOIT, a boolean saying whether to really install any cleanup handler. (__libc_cleanup_region_end): Do nothing if start's DOIT arg was zero. (__libc_cleanup_end): Likewise. * stdio-common/vfscanf.c (LOCK_STREAM): Pass new arg. * stdio-common/vfprintf.c (buffered_vfprintf, vfprintf): Likewise. * sysdeps/mach/hurd/bits/stdio-lock.h (_IO_cleanup_region_start): Likewise. * misc/syslog.c (vsyslog, openlog, closelog): Likewise. * sysdeps/generic/bits/stdio-lock.h (_IO_cleanup_region_start, _IO_cleanup_region_start_noarg): Likewise. --- bits/stdio-lock.h | 15 +++++++++------ sysdeps/generic/bits/stdio-lock.h | 15 +++++++++------ 2 files changed, 18 insertions(+), 12 deletions(-) diff --git a/bits/stdio-lock.h b/bits/stdio-lock.h index f7c61088f1..5b1c1b082e 100644 --- a/bits/stdio-lock.h +++ b/bits/stdio-lock.h @@ -1,4 +1,4 @@ -/* Thread package specific definitions of stream lock type.
