Add your own callback when a channel has finished playing.
void Mix_ChannelFinished(void (SDLCALL *channel_finished)(int channel));
channel_finished |
callback function |
NULL to disable callback. The callback may be called from the mixer's audio callback or it could be called as a result of Mix_HaltChannel(), etc. do not call SDL_LockAudio() from this callback; you will either be inside the audio callback, or SDL_mixer will explicitly lock the audio before calling your callback.
This function is available since SDL_mixer 2.0.0.
