From b8824abce229cd6b2266a23eaeef2d3b49cf09d1 Mon Sep 17 00:00:00 2001 From: Jim Meyering Date: Wed, 21 Jan 2004 22:55:51 +0000 Subject: [PATCH] (usage): Use EXIT_SUCCESS, not 0, for clarity. (main): Don't assume EXIT_FAILURE == 1, as POSIX doesn't require it. --- src/df.c | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-) diff --git a/src/df.c b/src/df.c index 14a83bc812..e348f32536 100644 --- a/src/df.c +++ b/src/df.c @@ -1,5 +1,5 @@ /* df - summarize free disk space - Copyright (C) 91, 1995-2003 Free Software Foundation, Inc. + Copyright (C) 91, 1995-2004 Free Software Foundation, Inc.
