NAME
dat_evd_free - destroy an instance of the Event Dispatcher SYNOPSIS
cc [ flag... ] file... -ldat [ library... ] #include <dat/udat.h> DAT_RETURN dat_evd_free ( IN DAT_EVD_HANDLE evd_handle ) PARAMETERS
evd_handle Handle for an instance of the Event Dispatcher. DESCRIPTION
The dat_evd_free() function destroys a specified instance of the Event Dispatcher. All events on the queue of the specified Event Dispatcher are lost. The destruction of the Event Dispatcher instance does not have any effect on any DAT Objects that originated an Event Stream that had fed events to the Event Dispatcher instance. There should be no event streams feeding the Event Dispatcher and no threads blocked on the Event Dispatcher when the EVD is being closed as at the time when it was created. Use of the handle of the destroyed Event Dispatcher in any consequent operation fails. RETURN VALUES
DAT_SUCCESS The operation was successful. DAT_INVALID_HANDLE The evd_handle parameter is invalid DAT_INVALID_STATE Invalid parameter. There are Event Streams associated with the Event Dispatcher feeding it. USAGE
Consumers are advised to destroy all Objects that originate Event Streams that feed an instance of the Event Dispatcher before destroying it. An exception to this rule is Event Dispatchers of an IA. Freeing an IA automatically destroys all Objects associated with it directly and indirectly, including Event Dispatchers. 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
