Arguments

       dpy     Specifies the display screen on which the X Server is to accept
               requests from X clients.  If the display option is  not  speci-

               ronment variable.  The display  option  has  the  format  host-
               name:number.   Using  two  colons (::) instead of one (:) indi-
               cates that DECnet is to be used for transport.

               ated   when  its  attributes  are  changed  using  XvSetPortAt-
               tribute(3X).

       onoff   Specifies whether notification is to be enabled or disabled.
