* gdata_access_handler_get_rules:
* @self: a #GDataAccessHandler
* @service: a #GDataService
* @cancellable: (allow-none): optional #GCancellable object, or %NULL
* @progress_callback: (allow-none) (scope call) (closure progress_user_data): a #GDataQueryProgressCallback to call when a rule is loaded, or %NULL
* @progress_user_data: (closure): data to pass to the @progress_callback function
* @error: a #GError, or %NULL
*
* Retrieves a #GDataFeed containing all the access rules which apply to the given #GDataAccessHandler. Only the owner of a #GDataAccessHandler may
* view its rule feed.
*
* If @cancellable is not %NULL, then the operation can be cancelled by triggering the @cancellable object from another thread.
* If the operation was cancelled, the error %G_IO_ERROR_CANCELLED will be returned.
*
* A %GDATA_SERVICE_ERROR_PROTOCOL_ERROR will be returned if the server indicates there is a problem with the query.
*
* For each rule in the response feed, @progress_callback will be called in the main thread. If there was an error parsing the XML response,
* a #GDataParserError will be returned.
*
* Return value: (transfer full): a #GDataFeed of access control rules, or %NULL; unref with g_object_unref()
*
* Since: 0.3.0
