<p>This function is used to give the caller a connection to Tracker they can
use for future requests. The best backend available to connect to
Tracker is returned. These backends include direct-access (for read-only
queries) and D-Bus (for both read and write queries).</p>
<p>You can use <GTKDOCLINK HREF="tracker-overview-environment-variables">
environment variables</GTKDOCLINK> to influence how backends are used. If
no environment variables are provided, both backends are loaded and
chosen based on their merits. If you try to force a backend for a query
which it won't support (i.e. an update for a read-only backend), you will
see critical warnings.</p>
<p>When calling either <a class="link" href="TrackerSparqlConnection.html#tracker-sparql-connection-get" title="tracker_sparql_connection_get ()"><code class="function">tracker_sparql_connection_get()</code></a>,
<code class="function">tracker_sparql_connection_get_direct()</code> or the asynchronous variants of
these functions, a mutex is used to protect the loading of backends
against potential race conditions. For synchronous calls, this function
will always block if a previous connection get method has been called.</p>
<p>All backends will call the D-Bus tracker-store API <code class="function">Wait()</code> to make sure
the store and databases are in the right state before any user based
requests can proceed. There may be a small delay during this call if the
databases weren't shutdown cleanly and need to be checked on start up. If
the journal needs to be replayed in such an event, the delay may be
substantial while data is restored as best as possible.</p>
