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.
