From 62495816a5df7632ef6cc6f0e6f09e135aa763a1 Mon Sep 17 00:00:00 2001 From: Roland McGrath Date: Wed, 11 Nov 1998 09:56:51 +0000 Subject: [PATCH] 1998-11-11 Roland McGrath * hurd/hurdsig.c (_hurdsig_init): Take new args, INTARRAY and INTARRAYSIZE. Initialize main thread's sigstate from INIT_SIG* ints. * hurd/hurd/signal.h: Update _hurdsig_init decl. * hurd/hurdinit.c (_hurd_proc_init): Take new args, INTARRAY and INTARRAYSIZE, pass them down to _hurdsig_init. * hurd/hurd.h: Update _hurd_proc_init decl. --- hurd/hurd.h | 9 ++++++--- hurd/hurd/signal.h | 7 ++++--- hurd/hurdinit.c | 11 +++++------ hurd/hurdsig.c | 26 +++++++++++++++++++++----- 4 files changed, 36 insertions(+), 17 deletions(-) diff --git a/hurd/hurd.h b/hurd/hurd.h index eb445d4..98d726a 100644 --- a/hurd/hurd.h +++ b/hurd/hurd.h @@ -1,4 +1,4 @@ -/* Copyright (C) 1993, 1994, 1995, 1996, 1997 Free Software Foundation, Inc. +/* Copyright (C) 1993, 94, 95, 96, 97, 98 Free Software Foundation, Inc.
