From b88ff80f703931b368d27ebd898accdae5b31e60 Mon Sep 17 00:00:00 2001 From: Eric Andersen Date: Wed, 2 Jan 2002 12:18:50 +0000 Subject: Once again, rework the signal handling to be even more correct. We no longer segfault when running test/signal/sigchld.c, which exposed a bit of a rats nest. The problem ended up being a erroneous syscall defination, but in the process of finding that out, I scrubbed things up nicely and adapted things to use the rt_ signals if they are available. This now passes all the signal tests. -Erik --- libc/signal/sigignore.c | 36 ++++++++++++++++++++++++++++++++++++ 1 file changed, 36 insertions(+) create mode 100644 libc/signal/sigignore.c (limited to 'libc/signal/sigignore.c') diff --git a/libc/signal/sigignore.c b/libc/signal/sigignore.c new file mode 100644 index 000000000..64d1852ab --- /dev/null +++ b/libc/signal/sigignore.c @@ -0,0 +1,36 @@ +/* Set the disposition of SIG to SIG_IGN. + Copyright (C) 1998 Free Software Foundation, Inc. + This file is part of the GNU C Library. + Contributed by Ulrich Drepper , 1998. + + The GNU C Library is free software; you can redistribute it and/or + modify it under the terms of the GNU Library General Public License as + published by the Free Software Foundation; either version 2 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.
