                 from each other.

       sequence  The sequence number of the last request processed by the X11 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_device_state_reply.

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

ERRORS
