From: Mark Kettenis Date: Fri, 18 Mar 2005 20:46:38 +0000 (+0000) Subject: * utils.c (safe_strerror): Use xsnprintf instead of sprintf. X-Git-Tag: csl-arm-20050325-branchpoint~94 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=8cf46f625a7407f692fbea17719666fd8713917c;p=external%2Fbinutils.git * utils.c (safe_strerror): Use xsnprintf instead of sprintf. (decimal2str, octal2str): Change to return a string allocated by get_cell. Use xsnprint instead of snprintf. (paddr_u, paddr_d): Adjust for changed calling convention of decimal2str. (phex, phex_nz, hex_string): Use xsnprintf instead of snprintf. (int_string): Likewise.
