The type of this reply, in this case XCB_SYNC_QUERY_COUNTER. This field is also present in the xcb_generic_reply_t and can be used to tell replies apart from each other.
The sequence number of the last request processed by the X11 server.

TODO: NOT YET DOCUMENTED.

Returns an xcb_sync_query_counter_cookie_t. Errors have to be handled when calling the reply function xcb_sync_query_counter_reply.

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

This request does never generate any errors.
