$ICC_DISCONNECTW

   Terminates a link between two ICC associations.

   The $ICC_DISCONNECTW service completes synchronously; that is,
   it returns to the caller after the connection has completely
   finished the disconnection request.

   For asynchronous completion, use the $ICC_DISCONNECT service;
   $ICC_DISCONNECT returns to the caller as soon as the
   disconnection request has been sent to the transport layer,
   without waiting for notification that the disconnection has
   completed.

   On Alpha and Integrity server systems, this service accepts 64-
   bit addresses.
