Subject: [PATCH 17/17] commands: loadb: Make use of open_and_lseek()
Date: Wed,  6 Mar 2019 23:49:26 -0800	[thread overview]
Message-ID: <20190307074926.20539-18-andrew.smirnov@gmail.com> (raw)
In-Reply-To: <20190307074926.20539-1-andrew.smirnov@gmail.com>

Save a bit of extra code by replacing explict calls to open() and
lseek() with a single call to open_and_lseek().
