DAT_EVD_CLEAR_UNWAITABLE(3DAT)DAT_EVD_CLEAR_UNWAITABLE(3DAT)NAMEdat_evd_clear_unwaitable - transition the Event Dispatcher into a wait‐
able state
SYNOPSIS
cc [ flag... ] file... -ldat [ library... ]
#include <dat/udat.h>
DAT_RETURN
dat_evd_clear_unwaitable(
IN DAT_EVD_HANDLE evd_handle
)
PARAMETERS
evd_handle
Handle for an instance of Event Dispatcher.
DESCRIPTION
The dat_evd_clear_unwaitable() transitions the Event Dispatcher into a
waitable state. In this state, calls to dat_evd_wait(3DAT) are permit‐
ted 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).
RETURN VALUES
DAT_SUCCESS
The operation was successful.
DAT_INVALID_HANDLE
The evd_handle parameter is invalid.
