Subject: [spp] [PATCH 3/6] spp_vf: remove no meaning int variables
Date: Fri, 2 Aug 2019 18:33:55 +0900 [thread overview]
Message-ID: <20190802093358.13696-4-yasufum.o@gmail.com> (raw)
In-Reply-To: <20190802093358.13696-1-yasufum.o@gmail.com>
In main(), there are many no meaning variables for receiveing results
of functions such as `ret_do` or `ret_parse` or so and each of which is
used only one time for checking. It is enough by using `int ret`
defined at the head of the function.
