Subject: [PATCH 34/36] lib: introduce notmuch_database_create_with_config
Date: Sun,  3 Jan 2021 19:35:45 -0400	[thread overview]
Message-ID: <20210103233547.122707-35-david@tethera.net> (raw)
In-Reply-To: <20210103233547.122707-1-david@tethera.net>

This takes a config path parameter, and can use that to decide the
new database location.
