DAT_RETURN
dat_evd_clear_unwaitable(
IN DAT_EVD_HANDLE evd_handle
)
Handle for an instance of Event Dispatcher.
The dat_evd_clear_unwaitable() transitions the Event Dispatcher into a waitable state. In this state, calls to dat_evd_wait(3DAT) are permitted on the EVD. The actual state of the Event Dispatcher is accessible through dat_evd_query(3DAT) and is DAT_EVD_WAITABLE after the return of this operation.
This call does not affect a CNO associated with this EVD at all. Events arriving on the EVD after it is set waitable still trigger the CNO (if appropriate), and can be retrieved with dat_evd_dequeue(3DAT).
The operation was successful.
The evd_handle parameter is invalid.
