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. ATTRIBUTES

NAME
dat_evd_resize - modify the size of the event queue of Event Dispatcher SYNOPSIS
cc [ flag... ] file... -ldat [ library... ] #include <dat/udat.h> DAT_RETURN dat_evd_resize( IN DAT_EVD_HANDLE evd_handle, IN DAT_COUNT evd_min_qlen ) PARAMETERS
evd_handle Handle for an instance of Event Dispatcher. evd_min_qlen New number of events the Event Dispatcher event queue must hold. DESCRIPTION
The dat_evd_resize() function modifies the size of the event queue of Event Dispatcher. Resizing of Event Dispatcher event queue should not cause any incoming or current events on the event queue to be lost. If the number of entries on the event queue is larger then the requested evd_min_qlen, the operation can return DAT_INVALID_STATE and not change an instance of Event Dispatcher RETURN VALUES
DAT_SUCCESS The operation was successful. DAT_INVALID_HANDLE The evd_handle parameter is invalid. DAT_INVALID_PARAMETER The evd_min_qlen parameter is invalid DAT_INSUFFICIENT_RESOURCES The operation failed due to resource limitations DAT_INVALID_STATE Invalid parameter. The number of entries on the event queue of the Event Dispatcher exceeds the requested event queue length. USAGE
This operation is useful when the potential number of events that could be placed on the event queue changes dynamically. ATTRIBUTES
