From 8024f33e45a2ba3b47f3a1362711a86bd19f57da Mon Sep 17 00:00:00 2001 From: Jim Meyering Date: Tue, 18 Jan 2000 07:28:47 +0000 Subject: (interrupt_handler): Don't use SA_INTERRUPT to decide whether to call sigaction, as POSIX.1 doesn't require SA_INTERRUPT and some systems (e.g. Solaris 7) don't define it. Use SA_NOCLDSTOP instead; it's been part of POSIX.1 since day 1 (in 1988). (install_handler): Use SA_NOCLDSTOP, not _POSIX_VERSION, to decide whether to call sigaction; this fixes an old typo. --- src/dd.c | 10 +++++----- 1 file changed, 5 insertions(+), 5 deletions(-) (limited to 'src') diff --git a/src/dd.c b/src/dd.c index 4bb46c6c9..f2b8a63cb 100644 --- a/src/dd.c +++ b/src/dd.c @@ -1,5 +1,5 @@ /* dd -- convert a file while copying it. - Copyright (C) 85, 90, 91, 1995-1999 Free Software Foundation, Inc. + Copyright (C) 85, 90, 91, 1995-2000 Free Software Foundation, Inc.
