Subject: [PATCH v3 05/16] daemonize(): set a flag before exiting the main process
Date: Wed, 6 Apr 2016 18:11:51 -0400 [thread overview]
Message-ID: <1459980722-4836-6-git-send-email-dturner@twopensource.com> (raw)
In-Reply-To: <1459980722-4836-1-git-send-email-dturner@twopensource.com>
From: Nguyễn Thái Ngọc Duy <pclouds@gmail.com>
This allows signal handlers and atexit functions to realize this
situation and not clean up.
