NAME
     dat_evd_set_unwaitable -  transition  the  Event  Dispatcher
     into an unwaitable state

SYNOPSIS
     cc [ flag... ] file... -ldat [ library... ]
     #include 

     DAT_RETURN
         dat_evd_set_unwaitable(
         IN    DAT_EVD_HANDLE    evd_handle
         )


PARAMETERS
     evd_handle    Handle for an instance of Event Dispatcher.


DESCRIPTION
     The   dat_evd_set_unwaitable()   transitions    the    Event
     Dispatcher into an unwaitable state. In this state, calls to
     dat_evd_wait(3DAT)    return    synchronously     with     a
     DAT_INVALID_STATE  error,  and  threads  already  blocked in
     dat_evd_wait()   are   awakened   and    return    with    a
     DAT_INVALID_STATE  error  without  any further action by the
     Consumer. The actual state of the Event Dispatcher is acces-
     sible  through dat_evd_query(3DAT) and is DAT_EVD_UNWAITABLE
     after the return of this operation.


     This call does not affect a CNO associated with this EVD  at
     all.  Events  arriving on the EVD after it is set unwaitable
     still trigger the CNO (if appropriate), and can be retrieved
     with  dat_evd_dequeue(3DAT).  Because events can arrive nor-
     mally on the EVD, the EVD might overflow;  the  Consumer  is
     expected to protect against this possibility.

RETURN VALUES
     DAT_SUCCESS           The operation was successful.


     DAT_INVALID_HANDLE    The evd_handle parameter is invalid.
