Subject: [PATCH 2/3] pager: refactor wait_for_pager() function
Date: Mon, 1 Feb 2021 15:49:20 +0100 [thread overview]
Message-ID: <20210201144921.8664-3-avarab@gmail.com> (raw)
In-Reply-To: <87im7cng42.fsf@evledraar.gmail.com>
Refactor the wait_for_pager() function. Since 507d7804c0b (pager:
don't use unsafe functions in signal handlers, 2015-09-04) the
wait_for_pager() and wait_for_pager_atexit() callers diverged on more
than they shared.
Let's extract the common code into a new close_pager_fds() helper, and
move the parts unique to the only to callers to those functions.
