mixGetTrackAudioStream function mixer

Pointer<SdlAudioStream> mixGetTrackAudioStream(Pointer<MixTrack> track)

Query the SDL_AudioStream assigned to a track.

This returns the SDL_AudioStream object currently assigned to track through a call to MIX_SetTrackAudioStream(). If there is none assigned, or the track has an input that isn't an SDL_AudioStream (such as a MIX_Audio or SDL_IOStream), this will return NULL.

On various errors (MIX_Init() was not called, the track is NULL), this returns NULL, but there is no mechanism to distinguish errors from tracks without a valid input.

\param track the track to query. \returns an SDL_AudioStream if available, NULL if not.

\threadsafety It is safe to call this function from any thread.

\since This function is available since SDL_mixer 3.0.0.
