From ce5becbb616637753e2c7e441c5e019f3864b3f7 Mon Sep 17 00:00:00 2001 From: Thomas Wood Date: Thu, 10 Oct 2013 12:23:19 +0100 Subject: [PATCH] testdisplay: Allow getopt to print error messages By not assigning opterr, getopt will print its own error message that includes information about whether an option is unknown or just requires an additional argument.
