       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).

DESCRIPTION
       This is used to determine the version of	the MIT-SHM extension support-
       ed  by  the X server.  Clients MUST NOT make other requests in this ex-
       tension until a reply to	this requests indicates	the X server  supports
       them.

RETURN VALUE
       Returns	an  xcb_shm_query_version_cookie_t.  Errors have to be handled
       when calling the	reply function xcb_shm_query_version_reply.

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

ERRORS
       This request does never generate	any errors.
