<title>Description</title>
<p>Performs a deep copy of the <code>database</code> struct and its configuration. Useful if you intend to call <code xref="mongoc_database_set_write_concern">mongoc_database_set_write_concern</code>, <code xref="mongoc_database_set_read_prefs">mongoc_database_set_read_prefs</code>, or <code xref="mongoc_database_set_read_concern">mongoc_database_set_read_concern</code>, and want to preserve an unaltered copy of the struct.</p>
<p>This function does <em>not</em> copy the contents of the database on the MongoDB server; use the <link xref="common-task-examples#copydb"><code>copydb</code> command</link> for that purpose.</p>
</section>
<section id="return">
<title>Returns</title>
<p>A newly allocated <code xref="mongoc_database_t">mongoc_database_t</code> that should be freed with <code xref="mongoc_database_destroy">mongoc_database_destroy()</code> when no longer in use.</p>
