$TRANS_EVENTW

   Forces a transaction state change for a transaction in which
   there is at least one RM participant that has specified the
   DDTM$M_COORDINATOR flag.

   $TRANS_EVENTW always waits for the request to complete before
   returning to the caller. Other than this, it is identical to
   $TRANS_EVENT.
