Subject: [PATCH 04/38] lib/open: add support for config profiles and default locations
Date: Sat, 16 Jan 2021 13:03:32 -0400 [thread overview]
Message-ID: <20210116170406.842014-5-david@tethera.net> (raw)
In-Reply-To: <20210116170406.842014-1-david@tethera.net>
This commit fills in the remainder of the documented functionality for
n_d_open_with_config with respect to config file location. Similar
searching default locations of the database file still needs to be
added.
