Microsoft DirectX 8.1 (C++) |
The SetNotifyFlags method enables or disables event notifications.
Syntax
HRESULT SetNotifyFlags(
long lNoNotifyFlags
);
Parameters
lNoNotifyFlags
[in] Value indicating whether to enable or disable event notifications. Must be one of the following values:
Value | Description |
Zero | Enable event notifications. |
AM_MEDIAEVENT_NONOTIFY | Disable event notifications. |
Return Value
Returns S_OK if successful, or E_INVALIDARG if the lNoNotifyFlags parameter is invalid.
Remarks
By default, the Filter Graph Manager posts event notifications for the application. If the lNoNotifyFlags parameter is AM_MEDIAEVENT_NONOTIFY, the Filter Graph Manager clears any pending event notifications from the queue, and does not post any new ones.
If event notifications are disabled, the handle returned by the IMediaEvent::GetEventHandle method is signaled at the end of each streamthat is, whenever the Filter Graph Manager receives an EC_COMPLETE event.
