From 2c9499bf272e06a62902711c6c20621ef3f80e64 Mon Sep 17 00:00:00 2001 From: Lukas Fleischer Date: Thu, 1 Mar 2012 23:15:38 +0100 Subject: Use strcmp() instead of strncmp() strncmp() isn't intended to be a secure strcmp() replacement, it is designed to be used if you want to compare the first n characters of two strings. Since we always compare character pointers with string literals, switch to using strcmp() everywhere.
