From 8d743926f496f69fb86a532f6db856b41e357b75 Mon Sep 17 00:00:00 2001 From: Jason Molenda Date: Fri, 6 Feb 1998 01:22:01 +0000 Subject: [PATCH] * top.c (do_nothing): Remove signal handler after signal is caught. Helpful for SYSV systems where two ^-\s will cause problems. Should have no effect on BSD systems. --- gdb/top.c | 7 +++++++ 1 file changed, 7 insertions(+) diff --git a/gdb/top.c b/gdb/top.c index 054bcc781df..fd5f316e2e2 100644 --- a/gdb/top.c +++ b/gdb/top.c @@ -1914,6 +1914,13 @@ static void do_nothing (signo) int signo; { + /* Under System V the default disposition of a signal is reinstated after + the signal is caught and delivered to an application process.
