dat_evd_post_se(3DADirect Access Transport Library Functidat_evd_post_se(3DAT)NAMEdat_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 Dis‐
patcher 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 responsi‐
bility.
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 Dis‐
patcher 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.
