dat_evd_free

dat_evd_free(3DAT)				     Direct Access Transport Library Functions					dat_evd_free(3DAT)

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.
