From cac289316bed4282f798dbe710398e6f53f66f1f Mon Sep 17 00:00:00 2001 From: Thomas Huehn Date: Fri, 5 Jul 2013 12:04:14 +0200 Subject: [PATCH] bugfix of error handling while open() The normal return value from open() is a non-negative integer. In the case of an error, a value of -1 is returned instead.
