 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 parameters 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 overflow
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.
