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/sigrelse.c | 38 ++++++++++++++++++-------------------- 1 file changed, 18 insertions(+), 20 deletions(-) (limited to 'libc/signal/sigrelse.c') diff --git a/libc/signal/sigrelse.c b/libc/signal/sigrelse.c index 725a551bc..ae3b20ae2 100644 --- a/libc/signal/sigrelse.c +++ b/libc/signal/sigrelse.c @@ -4,39 +4,37 @@ Contributed by Ulrich Drepper , 1998.
