From 3ba34141da77a24c251ee6530f3f72a366fe556e Mon Sep 17 00:00:00 2001 From: Philipp Stephani Date: Fri, 25 Dec 2020 11:33:02 +0100 Subject: Import posix_spawn from Gnulib. posix_spawn is less error-prone than vfork + exec, and can make use of system-specific optimizations like `clone' on Linux. Import Gnulib replacement so that we can use recent additions like `posix_spawn_file_actions_addchdir'. The only manual change are to admin/merge-gnulib and .gitignore. All other changes are due to rerunning merge-gnulib. * admin/merge-gnulib (GNULIB_MODULES): Add posix_spawn-related modules. * .gitignore: Add new generated files. --- lib/spawnattr_setdefault.c | 33 +++++++++++++++++++++++++++++++++ 1 file changed, 33 insertions(+) create mode 100644 lib/spawnattr_setdefault.c (limited to 'lib/spawnattr_setdefault.c') diff --git a/lib/spawnattr_setdefault.c b/lib/spawnattr_setdefault.c new file mode 100644 index 00000000000..01c29e94847 --- /dev/null +++ b/lib/spawnattr_setdefault.c @@ -0,0 +1,33 @@ +/* Copyright (C) 2000, 2009-2020 Free Software Foundation, Inc. + This file is part of the GNU C Library. + + This program is free software: you can redistribute it and/or modify + it under the terms of the GNU General Public License as published by + the Free Software Foundation; either version 3 of the License, or + (at your option) any later version. + + This program 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.
