◆ GetPlayingSegmentInfo()

AKSOUNDENGINE_API AKRESULT AK::MusicEngine::GetPlayingSegmentInfo	(	AkPlayingID	in_PlayingID,
		AkSegmentInfo &	out_segmentInfo,
		bool	in_bExtrapolate = `true`
	)

Query information on the active segment of a music object that is playing. Use the playing ID that was returned from AK::SoundEngine::PostEvent(), provided that the event contained a play action that was targeting a music object. For any configuration of interactive music hierarchy, there is only one segment that is active at a time. To be able to query segment information, you must pass the AK_EnableGetMusicPlayPosition flag to the AK::SoundEngine::PostEvent() method. This informs the sound engine that the source associated with this event should be given special consideration because GetPlayingSegmentInfo() can be called at any time for this AkPlayingID. Notes:

If the music object is a single segment, you will get negative values for AkSegmentInfo::iCurrentPosition during the pre-entry. This will never occur with other types of music objects because the pre-entry of a segment always overlaps another active segment.
The active segment during the pre-entry of the first segment of a Playlist Container or a Music Switch Container is "nothing", as well as during the post-exit of the last segment of a Playlist (and beyond).
When the active segment is "nothing", out_uSegmentInfo is filled with zeros.
If in_bExtrapolate is true (default), AkSegmentInfo::iCurrentPosition is corrected by the amount of time elapsed since the beginning of the audio frame. It is thus possible that it slightly overshoots the total segment length.
반환값
AK_Success if there is a playing music structure associated with the specified playing ID.
