REPLY FIELDS response_type The type of this reply, in this case XCB_XV_QUERY_IMAGE_AT- TRIBUTES. This field is also present in the xcb_generic_re- ply_t and can be used to tell replies apart from each other. sequence The sequence number of the last request processed by the X11 server. length The length of the reply, in words (a word is 4 bytes). num_planes TODO: NOT YET DOCUMENTED. data_size TODO: NOT YET DOCUMENTED. width TODO: NOT YET DOCUMENTED. height TODO: NOT YET DOCUMENTED. DESCRIPTION RETURN VALUE Returns an xcb_xv_query_image_attributes_cookie_t. Errors have to be handled when calling the reply function xcb_xv_query_image_attribut- es_reply. If you want to handle errors in the event loop instead, use xcb_xv_query_image_attributes_unchecked. See xcb-requests(3) for de- tails. ERRORS This request does never generate any errors.
