$ICC_TRANSCEIVEW

   Sends a single message over a connection and waits for a reply.

   The $ICC_TRANSCEIVEW service completes synchronously; that is, it
   returns to the caller when the data from the reply is available.

   For asynchronous completion, use the $ICC_TRANSCEIVE service;
   $ICC_TRANSCEIVE returns to the caller when the transmit portion
   of the tranceive request has been queued to the transport layer,
   but without waiting for notification that the transport layer has
   released control of the data buffer or for the reply data from
   the receiving end of the connection.

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