From 329a875d8001b40ff0ed8d621c37e1bc1d7813a6 Mon Sep 17 00:00:00 2001 From: Ben Pfaff Date: Tue, 9 Feb 2010 21:13:59 -0800 Subject: [PATCH] levene: Write null pointers as NULL instead of as 0. Using 0 as a null pointer constant is not incorrect but NULL is the style used in most of PSPP. Found using coccinelle and coccicheck (http://coccinelle.lip6.fr/). --- src/math/levene.c | 12 ++++++------ 1 file changed, 6 insertions(+), 6 deletions(-) diff --git a/src/math/levene.c b/src/math/levene.c index f7e26999..5ff474dc 100644 --- a/src/math/levene.c +++ b/src/math/levene.c @@ -1,5 +1,5 @@ /* PSPP - a program for statistical analysis. - Copyright (C) 2004, 2009 Free Software Foundation, Inc. + Copyright (C) 2004, 2009, 2010 Free Software Foundation, Inc.
