		 be used to tell replies apart 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).

       width	 TODO: NOT YET DOCUMENTED.

DESCRIPTION
RETURN VALUE
       Returns	an  xcb_glx_get_histogram_cookie_t.  Errors have to be handled
       when calling the	reply function xcb_glx_get_histogram_reply.

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

ERRORS
       This request does never generate	any errors.
