| Microsoft DirectX 9.0 SDK Update (October 2004) |
The RemoveNotificationType method removes a previously added notification type from the performance. All segments and tracks are updated by a call to their RemoveNotificationType methods.
Syntax
HRESULT RemoveNotificationType(
REFGUID rguidNotificationType
);
Parameters
rguidNotificationType
Reference to (C++) or address of (C) the identifier of the notification type to remove. (For the defined types, see DMUS_NOTIFICATION_PMSG.) If this value is GUID_NULL, all notifications are removed.
Return Values
If the method succeeds, the return value is S_OK or S_FALSE (see Remarks).
If it fails, the method can return E_POINTER.
Remarks
S_FALSE is returned when rguidNotificationType is not an active notification.
If a notification was added to a segment that has stopped playing, the performance cannot remove the notification type from that segment because it no longer has a reference to the segment.
Requirements
Header: Dmusici.h
Library: Dmime.dll, Dmimed.dll
