From ff572a4a55cd3d693d5e5b3f0a9757b6b9088017 Mon Sep 17 00:00:00 2001 From: Sami Kerola Date: Sat, 22 Jan 2011 00:14:52 +0100 Subject: [PATCH] After fopen in ouput ioctl does like /dev/null which cause ENOTTY, and clean_up will see that without this reset. At least linux does this, and possibly some other systems. There's a report from FreeBSD 8.0 which matches quite well with the symptom.
