NAME

       dat_evd_post_se - post Software event to the Event Dispatcher event queue

SYNOPSIS

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

       DAT_RETURN
	   dat_evd_post_se(
	   IN	     DAT_EVD_HANDLE    evd_handle,
	   IN const  DAT_EVENT	       *event
	   )

PARAMETERS

       evd_handle      Handle for an instance of the Event Dispatcher

       event	       A pointer to a Consumer created Software Event.

DESCRIPTION

       The  dat_evd_post_se()  function posts Software events to the Event Dispatcher event queue. This is analogous to event arrival on the Event
       Dispatcher software Event Stream. The event that the Consumer provides adheres to the event format as defined in <dat.h>. The first element
       in  the	event provides the type of the event (DAT_EVENT_TYPE_SOFTWARE); the rest provide the event-type-specific parameters. These parame-
       ters are opaque to a Provider. Allocation and release of the memory referenced by the event pointer in a software event are the	Consumer's
       responsibility.

       There  is no ordering between events from different Event Streams. All the synchronization issues between multiple Consumer contexts trying
       to post events to an Event Dispatcher instance simultaneously are left to a Consumer.

       If the event queue is full, the operation is completed unsuccessfully and returns DAT_QUEUE_FULL. The event is not queued. The queue  over-
       flow condition does takes place and, therefore, the asynchronous Event Dispatcher is not effected.

RETURN VALUES

       DAT_SUCCESS	       The operation was successful.

       DAT_INVALID_HANDLE      The evd_handle parameter is invalid.

       DAT_INVALID_PARAMETER   The event parameter is invalid.

       DAT_QUEUE_FULL	       The Event Dispatcher queue is full.

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.
