From f73105ab42795422f131fb711712e3c860df982f Mon Sep 17 00:00:00 2001 From: Phil Sutter Date: Thu, 15 Oct 2015 21:01:16 +0200 Subject: [PATCH] ss: return -1 if an unrecognized option was given When getopt_long encounters an option which has not been registered, it returns '?'. React upon that and call usage() instead of help() so ss returns with a non-zero exit status.
