Subject: [Patch v5 5/8] lib: add a log function with output to a string in notmuch_database_t
Date: Tue, 24 Mar 2015 09:24:08 -0400 [thread overview]
Message-ID: <1427203451-1540-6-git-send-email-david@tethera.net> (raw)
In-Reply-To: <1427203451-1540-1-git-send-email-david@tethera.net>
In principle in the future this could do something fancier than sprintf.
