The <code class="methodname">Db::get_type()</code> method returns the type of the underlying access
method (and file format). The type value is one of DB_BTREE, DB_HASH,
DB_RECNO, or DB_QUEUE. This value may be used to determine the type
of the database after a return from <a class="xref" href="dbopen.html" title="Db::open()">Db::open()</a>
with the <span class="bold"><strong>type</strong></span> parameter set to DB_UNKNOWN.

The <code class="methodname">Db::get_type()</code> <span>
