Subject: [iptables PATCH 08/12] xtables-save: Pass optstring/longopts to xtables_save_main()
Date: Sat, 20 Jul 2019 18:30:22 +0200 [thread overview]
Message-ID: <20190720163026.15410-9-phil@nwl.cc> (raw)
In-Reply-To: <20190720163026.15410-1-phil@nwl.cc>
Introduce variables for the different optstrings so short and long
options live side-by-side.
In order to make xtables_save_main() more versatile, pass optstring and
longopts via parameter.
