Queries the stream information asynchronously.
When the operation is finished <em class="parameter"><code>callback</code></em> will be called. 
You can then call <a class="link" href="GFileInputStream.html#g-file-input-stream-query-info-finish"><code class="function">g_file_input_stream_query_info_finish()</code></a> 
to get the result of the operation.
</p>
<p>
For the synchronous version of this function, 
see <a class="link" href="GFileInputStream.html#g-file-input-stream-query-info"><code class="function">g_file_input_stream_query_info()</code></a>. 
</p>
<p>
If <em class="parameter"><code>cancellable</code></em> is not <a
href="/usr/share/gtk-doc/html/liboil/liboil-liboiljunk.html#NULL:CAPS"
><code class="literal">NULL</code></a>, then the operation can be cancelled by
triggering the cancellable object from another thread. If the operation
was cancelled, the error <a class="link" href="gio-GIOError.html#G-IO-ERROR-CANCELLED:CAPS"><code class="literal">G_IO_ERROR_CANCELLED</code></a> will be set</p>
