From 9cbbc4aebe27c84d8e598994e176493f339ab1c1 Mon Sep 17 00:00:00 2001 From: Pino Toscano Date: Wed, 23 Jan 2013 17:25:53 +0100 Subject: ulimit: move linux implementation as posix The linux implementation of ulimit works correctly and has nothing specific to Linux, so move it as general posix implementation. --- sysdeps/posix/ulimit.c | 91 ++++++++++++++++++++++++++++++++++++++++ sysdeps/unix/sysv/linux/ulimit.c | 91 ---------------------------------------- 2 files changed, 91 insertions(+), 91 deletions(-) create mode 100644 sysdeps/posix/ulimit.c delete mode 100644 sysdeps/unix/sysv/linux/ulimit.c (limited to 'sysdeps') diff --git a/sysdeps/posix/ulimit.c b/sysdeps/posix/ulimit.c new file mode 100644 index 0000000000..8c382ac18f --- /dev/null +++ b/sysdeps/posix/ulimit.c @@ -0,0 +1,91 @@ +/* Copyright (C) 1991-2013 Free Software Foundation, Inc. + This file is part of the GNU C Library. + + 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.
