From 011f2e9bdddcbfe65da397629bca87d167313a28 Mon Sep 17 00:00:00 2001 From: Simon Arlott Date: Sat, 7 Mar 2009 00:06:24 +0000 Subject: truncate buffer before reading empty files If readfile() reads an empty file, fgets() won't truncate the buffer and it'll still contain the contents of the previously read file.
