DESCRIPTION

RETURN VALUE

88       Returns an xcb_xv_query_image_attributes_cookie_t. Errors have to be
89       handled when calling the reply function xcb_xv_query_image_at‐
90       tributes_reply.
91
92       If you want to handle errors in the event loop instead, use
93       xcb_xv_query_image_attributes_unchecked. See xcb-requests(3) for de‐
94       tails.
95
