                 XCB_XV_QUERY_IMAGE_ATTRIBUTES. This field is also present in
                 the xcb_generic_reply_t and can be used to tell replies apart
                 from each other.

                 server.

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_attributes_reply.

       If you want to handle errors in the event loop instead, use
       xcb_xv_query_image_attributes_unchecked. See xcb-requests(3) for
       details.
