NAME

       dat_evd_clear_unwaitable - transition the Event Dispatcher into a waitable state

SYNOPSIS

       cc [ flag... ] file... -ldat [ library... ]
       #include <dat/udat.h>

       DAT_RETURN
	   dat_evd_clear_unwaitable(
	   IN	 DAT_EVD_HANDLE    evd_handle
	   )

PARAMETERS

       evd_handle    Handle for an instance of Event Dispatcher.

DESCRIPTION

       The  dat_evd_clear_unwaitable() transitions the Event Dispatcher into a waitable state. In this state, calls to dat_evd_wait(3DAT) are per-
       mitted on the EVD. The actual state of the Event Dispatcher is accessible through dat_evd_query(3DAT) and  is  DAT_EVD_WAITABLE	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 waitable still trigger the CNO
       (if appropriate), and can be retrieved with dat_evd_dequeue(3DAT).

RETURN VALUES

       DAT_SUCCESS	     The operation was successful.

       DAT_INVALID_HANDLE    The evd_handle parameter is invalid.

NAME

       dat_evd_set_unwaitable - transition the Event Dispatcher into an unwaitable state

SYNOPSIS

       cc [ flag... ] file... -ldat [ library... ]
       #include <dat/udat.h>

       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 accessible 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 normally on the EVD, the EVD might over-
       flow; 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.
