Returns : |
void g_file_output_stream_query_info_async (GFileOutputStream *stream, char *attributes, int io_priority, GCancellable *cancellable, GAsyncReadyCallback callback, gpointer user_data);
Asynchronously queries the stream
for a GFileInfo. When completed,
callback
will be called with a GAsyncResult which can be used to
finish the operation with g_file_output_stream_query_info_finish()
.
For the synchronous version of this function, see
g_file_output_stream_query_info()
