67 response_type
68 The type of this reply, in this case XCB_XV_QUERY_IMAGE_AT‐
69 TRIBUTES. This field is also present in the xcb_generic_re‐
70 ply_t and can be used to tell replies apart from each other.
71
72 sequence The sequence number of the last request processed by the X11
73 server.
74
75 length The length of the reply, in words (a word is 4 bytes).

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
97 This request does never generate any errors.
