<p>
Requests an asynchronous close of the stream, releasing resources 
related to it. When the operation is finished <em class="parameter"><code>callback</code></em> will be 
called. You can then call <a class="link" href="GOutputStream.html#g-output-stream-close-finish"><code class="function">g_output_stream_close_finish()</code></a> to get 
the result of the operation.
</p>
<p>
For behaviour details see <a class="link" href="GOutputStream.html#g-output-stream-close"><code class="function">g_output_stream_close()</code></a>.
</p>
<p>
The asyncronous methods have a default fallback that uses threads 
to implement asynchronicity, so they are optional for inheriting 
classes. However, if you override one you must override all.</p>
