From 9f70985569888d68612012fcb538c47c154c1e8b Mon Sep 17 00:00:00 2001 From: Adhemerval Zanella Date: Wed, 20 Jan 2021 14:06:56 -0300 Subject: Consolidate pthread_atfork The pthread_atfork is similar between Linux and Hurd, only the compat version bits differs. The generic version is place at sysdeps/pthread with a common name. It also fixes an issue with Hurd license, where the static-only object did not use LGPL + exception. Checked on x86_64-linux-gnu, i686-linux-gnu, and with a build for i686-gnu. --- sysdeps/pthread/pthread_atfork.c | 58 ++++++++++++++++++++++++++++++++++++++++ 1 file changed, 58 insertions(+) create mode 100644 sysdeps/pthread/pthread_atfork.c (limited to 'sysdeps/pthread/pthread_atfork.c') diff --git a/sysdeps/pthread/pthread_atfork.c b/sysdeps/pthread/pthread_atfork.c new file mode 100644 index 0000000000..7646fe7efc --- /dev/null +++ b/sysdeps/pthread/pthread_atfork.c @@ -0,0 +1,58 @@ +/* Copyright (C) 2002-2021 Free Software Foundation, Inc. + This file is part of the GNU C Library. + Contributed by Ulrich Drepper , 2002. + + 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. + + In addition to the permissions in the GNU Lesser General Public + License, the Free Software Foundation gives you unlimited + permission to link the compiled version of this file with other + programs, and to distribute those programs without any restriction + coming from the use of this file.
