DESCRIPTION

RETURN VALUE

64       Returns an xcb_input_query_device_state_cookie_t. Errors have to be
65       handled when calling the reply function xcb_input_query_de‐
66       vice_state_reply.
67
68       If you want to handle errors in the event loop instead, use xcb_in‐
69       put_query_device_state_unchecked. See xcb-requests(3) for details.
