From c45e3fa9793a273a0eab40d1626bcda7d710552c Mon Sep 17 00:00:00 2001 From: Haru Date: Thu, 7 Aug 2014 03:39:13 +0200 Subject: Corrected several format-string errors through the code - Functions that expect a printf-style format string are now marked as such, so that gcc/clang will emit a warning warn you if you mismatch format string and arguments.
