From eb5a2ba5962579e514b377f5fdab7292be0fb2a7 Mon Sep 17 00:00:00 2001 From: "Daniel P. Berrange" Date: Tue, 5 Mar 2013 15:18:20 +0000 Subject: [PATCH] [zbin] Fix size used for memset in alloc_output_file MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The output->buf field is a pointer, not an array, so sizeof() is not applicable. We must use the allocated string length instead. Identified by gcc: util/zbin.c: In function ‘alloc_output_file’: util/zbin.c:146:37: warning: argument to ‘sizeof’ in ‘memset’ call is the same expression as the destination; did you mean to dereference it? [-Wsizeof-pointer-memaccess] memset ( output->buf, 0xff, sizeof ( output->buf ) ); Signed-off-by: Daniel P.
