IAudioSessionManager2::UnregisterSessionNotification method (audiopolicy.h)

  • Article

The UnregisterSessionNotification method deletes the registration to receive a notification when a session is created.

Syntax

HRESULT UnregisterSessionNotification(
  IAudioSessionNotification *SessionNotification
);

Parameters

SessionNotification

A pointer to the application's implementation of the IAudioSessionNotification interface. Pass the same interface pointer that was specified to the session manager in a previous call to IAudioSessionManager2::RegisterSessionNotification to register for notification.

If the UnregisterSessionNotification method succeeds, it calls the Release method on the application's IAudioSessionNotification interface.

Return value

If the method succeeds, it returns S_OK. If it fails, possible return codes include, but are not limited to, the values shown in the following table.

Return value Description
E_POINTER
 SessionNotification is NULL.

Remarks

The application calls this method when it no longer needs to receive notifications. The UnregisterSessionNotification method removes the registration of an IAudioSessionNotification interface that the application previously registered with the session manager by calling the IAudioSessionControl::RegisterAudioSessionNotification method.
