From f474c5031e5b8c5833342a504c6e33941a5103f0 Mon Sep 17 00:00:00 2001 From: Tobias Klauser Date: Thu, 8 Dec 2016 11:09:10 +0100 Subject: all: Remove unused longindex parameter to getopt_long() All tools (except mausezahn) use getopt_long() and pass a pointer to a local opt_index variable for the longindex parameter. However, this variable is never read afterwards. According to getopt(3) it's perfectly fine to pass NULL as the longindex parameter instead, so do that.
