<p>
Requests an asynchronous closes 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="GInputStream.html#g-input-stream-close-finish"><code class="function">g_input_stream_close_finish()</code></a> to get the result of the 
operation.
</p>
<p>
For behaviour details see <a class="link" href="GInputStream.html#g-input-stream-close"><code class="function">g_input_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>
