From 5362876b60ddecda43de07affc77ec8f13335512 Mon Sep 17 00:00:00 2001 From: hwangcc23 Date: Thu, 22 Jun 2017 22:53:08 +0800 Subject: [PATCH] i3-msg: Return an exit code upon missing -t arg If getopt() returns '?' (option with a missing argument), exit the program with an error code rather than continuing the execution.
