From 09402f5bc1d87787c84dbf75d41777c87b1ce40e Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Tue, 25 Mar 2003 20:41:26 +0000 Subject: Update. 2003-03-25 Ulrich Drepper * csu/tst-atomic.c: Adjust tests to what atomic_add_negative and atomic_add_zero were supposed to do. * include/atomic.h: Adjust atomic_add_negative and atomic_add_zero to x86 behavior. * sysdeps/generic/bits/typesizes.h (__TIMER_T_TYPE): Define as void*. This matches the new timer implementation. * sysdeps/unix/sysv/linux/bits/siginfo.h (struct siginfo): Adjust timer info for what the kernel provides these days. (struct sigevent): Add _tid field. Define SIGEV_THREAD_ID. * Versions.def (librt): Add GLIBC_2.3.3. * abilist/libpthread.abilist: Update for nptl. --- nptl/sysdeps/unix/sysv/linux/timer_delete.c | 94 +++++++++++++++++++++++++++++ 1 file changed, 94 insertions(+) create mode 100644 nptl/sysdeps/unix/sysv/linux/timer_delete.c (limited to 'nptl/sysdeps/unix/sysv/linux/timer_delete.c') diff --git a/nptl/sysdeps/unix/sysv/linux/timer_delete.c b/nptl/sysdeps/unix/sysv/linux/timer_delete.c new file mode 100644 index 0000000000..cf63364253 --- /dev/null +++ b/nptl/sysdeps/unix/sysv/linux/timer_delete.c @@ -0,0 +1,94 @@ +/* Copyright (C) 2003 Free Software Foundation, Inc. + This file is part of the GNU C Library. + Contributed by Ulrich Drepper , 2003. + + The GNU C Library is free software; you can redistribute it and/or + modify it under the terms of the GNU Lesser General Public License as + published by the Free Software Foundation; either version 2.1 of the + License, or (at your option) any later version. + + The GNU C Library is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
