IXAudio2SourceVoice::Discontinuity method
Notifies an XAudio2 voice that no more buffers are coming after the last one that is currently in its queue.
Syntax
HRESULT Discontinuity ();
Parameters
This method has no parameters.
Return value
Returns S_OK if successful, an error code otherwise.
Remarks
Discontinuity suppresses the warnings that normally occur in the debug build of XAudio2 when a voice runs out of audio buffers to play. It is preferable to mark the final buffer of a stream by tagging it with the XAUDIO2_END_OF_STREAM flag, but in some cases the client may not know that a buffer is the end of a stream until after the buffer has been submitted.
Because calling Discontinuity is equivalent to applying the XAUDIO2_END_OF_STREAM flag retroactively to the last buffer submitted, an OnStreamEnd callback will be made when this buffer completes.
Platform Requirements
Windows 10 (XAudio2.9); Windows 8, Windows Phone 8 (XAudio 2.8); DirectX SDK (XAudio 2.7)
