<p>
The <code class="methodname">DbStream::close()</code> method flushes any
unwritten data to disk, frees allocated resources, and closes the
underlying file which contains the external file. You open an external
file stream using <a class="xref" href="dbstream.html" title="Dbc::db_stream()">
<span>Dbc::db_stream()</span>
</a>.
</p>
<p>
Once this method is called, the stream can not be used again even
if this method returns an error.
</p>
<p>
Unless otherwise specified, the
<code class="methodname">DbStream::close()</code> <span>
<span>
method either returns a non-zero error value or throws an
exception that encapsulates a non-zero error value on
failure, and returns 0 on success.
