From mboxrd@z Thu Jan 1 00:00:00 1970 From: Mike Frysinger Subject: [PATCH 1/3] tracepath: re-use printf return in print_host Date: Sat, 19 Feb 2011 12:51:27 -0500 Message-ID: <1298137889-23969-1-git-send-email-vapier@gentoo.org> Cc: netdev@vger.kernel.org To: YOSHIFUJI Hideaki Return-path: Received: from smtp.gentoo.org ([140.211.166.183]:38670 "EHLO smtp.gentoo.org" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1752569Ab1BSRvc (ORCPT ); Sat, 19 Feb 2011 12:51:32 -0500 Sender: netdev-owner@vger.kernel.org List-ID: The printf funcs take an int for field widths, not a size_t. Also, since the printf funcs already return the length of chars displayed, use that value instead of re-calculating the length with strlen.
