From: Ben Pfaff Date: Wed, 8 Apr 2009 04:02:14 +0000 (-0700) Subject: Add "x" prefix to calls to plain malloc(), calloc(), strdup(), realloc(). X-Git-Tag: v0.7.3~174 X-Git-Url: https://pintos-os.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=8ef8acb7c70a321963d30f2264e8f91e16427fcf;p=pspp-builds.git Add "x" prefix to calls to plain malloc(), calloc(), strdup(), realloc(). In review commit 503f53bfdde "Read dictionary encoding from data files" I noticed uses of plain strdup() (not xstrdup()). Some greps showed that there were several other uses of strdup(), as well as calloc(), malloc(), and realloc(), in the source tree. This commit adds "x" prefixes to each of them, to ensure proper error handling. --- diff --git a/src/data/dictionary.c b/src/data/dictionary.c index b5b6cca5..2dd1dfc4 100644 --- a/src/data/dictionary.c +++ b/src/data/dictionary.c @@ -1,5 +1,5 @@ /* PSPP - a program for statistical analysis. - Copyright (C) 1997-9, 2000, 2006, 2007 Free Software Foundation, Inc. + Copyright (C) 1997-9, 2000, 2006, 2007, 2009 Free Software Foundation, Inc.
