REPLY FIELDS
       response_type
		 The  type  of	this  reply,  in this case XCB_INPUT_QUERY_DE-
		 VICE_STATE. This field	is also	present	in the xcb_generic_re-
		 ply_t and can be used to tell replies apart from each other.

		 server.

       length	 The length of the reply, in words (a word is 4	bytes).

       xi_reply_type
		 TODO: NOT YET DOCUMENTED.

       num_classes
		 TODO: NOT YET DOCUMENTED.

DESCRIPTION
RETURN VALUE
       Returns	an  xcb_input_query_device_state_cookie_t.  Errors  have to be
       handled	 when	calling	  the	reply	function   xcb_input_query_de-
       vice_state_reply.

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