* Gets the size of the loaded data from the @ostream.
* Gets the size of the currently allocated data area (availible from

* growable (no realloc was passed to g_memory_output_stream_new()) then

* Note that for growable streams the returned size may become invalid on

* Returns: the size of the stream's data
