From mboxrd@z Thu Jan 1 00:00:00 1970 From: David Gibson To: passt-dev@passt.top Subject: [PATCH 15/28] cppcheck: Use inline suppression for strtok() in conf.c Date: Wed, 28 Sep 2022 14:33:26 +1000 Message-ID: <20220928043339.613538-16-david@gibson.dropbear.id.au> In-Reply-To: <20220928043339.613538-1-david@gibson.dropbear.id.au> MIME-Version: 1.0 Content-Type: multipart/mixed; boundary="===============5055250719111645866==" --===============5055250719111645866== Content-Type: text/plain; charset="utf-8" Content-Transfer-Encoding: 7bit strtok() is non-reentrant and old-fashioned, so cppcheck would complains about its use in conf.c if it weren't suppressed. We're single threaded and strtok() is convenient though, so it's not really worth reworking at this time. Convert this to an inline suppression so it's adjacent to the code its annotating.
