evd_handle

Handle for an instance of Event Dispatcher.

The dat_evd_enable() function enables the Event Dispatcher so that the arrival of an event can trigger the associated CNO. The enabling and disabling EVD has no effect on direct waiters on the EVD. However, direct waiters effectively take ownership of the EVD, so that the specified CNO is not triggered even if is enabled.

If the Event Dispatcher is already enabled, this operation is no-op.

DAT_SUCCESS

The operation was successful.

DAT_INVALID_HANDLE

The evd_handle parameter is invalid.
