Subject: [PATCH 2/2] Simplify _notmuch_doc_id_set_init interface.
Date: Sun, 30 Jan 2011 23:22:33 -0500 [thread overview]
Message-ID: <1296447753-10109-3-git-send-email-amdragon@mit.edu> (raw)
In-Reply-To: <8762t8n22a.fsf@yoom.home.cworth.org>
Don't require the caller of _notmuch_doc_id_set_init to pass in a
correct bound; instead compute it from the array. This simplifies the
caller and makes this interface easier to use correctly.
