From 2c6167310efd894360b679d01398cc63214ca619 Mon Sep 17 00:00:00 2001 From: Marcelo Araujo Date: Fri, 15 Apr 2016 03:38:58 +0000 Subject: [PATCH] Use NULL instead of 0 for pointers. fopen(3) returns NULL in case it can't open the STREAM. fgetln(3) returns NULL if it can't get a line from a STREAM. malloc returns NULL if it can't allocate memory. --- usr.sbin/fmtree/excludes.c | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) diff --git a/usr.sbin/fmtree/excludes.c b/usr.sbin/fmtree/excludes.c index 21a49b04f74..9f1c5640570 100644 --- a/usr.sbin/fmtree/excludes.c +++ b/usr.sbin/fmtree/excludes.c @@ -69,10 +69,10 @@ read_excludes_file(const char *name) size_t len; fp = fopen(name, "r"); - if (fp == 0) + if (fp == NULL) err(1, "%s", name); - while ((line = fgetln(fp, &len)) != 0) { + while ((line = fgetln(fp, &len)) != NULL) { if (line[len - 1] == '\n') len--; if (len == 0) @@ -80,7 +80,7 @@ read_excludes_file(const char *name) str = malloc(len + 1); e = malloc(sizeof *e); - if (str == 0 || e == 0) + if (str == NULL || e == NULL) errx(1, "memory allocation error"); e->glob = str; memcpy(str, line, len);
