From 5e4db62662a40fd73c911218a79bb984dc169b18 Mon Sep 17 00:00:00 2001 From: Lukas Fleischer Date: Fri, 11 Nov 2011 12:00:57 +0100 Subject: src/io.c: Avoid use of memcpy() Use strncpy() and a proper limit, which ensures we never read more characters than the buffer can hold. Also, ensure we always null-terminate strings here.
