Set a callback that runs when a music object has stopped playing.
void Mix_HookMusicFinished(void (SDLCALL *music_finished)(void));
|music_finished||the callback function to become the new notification mechanism.|
This callback will fire when the currently-playing music has completed, or when it has been explicitly stopped from a call to Mix_HaltMusic. As such, this callback might fire from an arbitrary background thread at almost any time; try to limit what you do here.
It is legal to start a new music object playing in this callback (or restart the one that just stopped). If the music finished normally, this can be used to loop the music without a gap in the audio playback.
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.
A NULL pointer will disable the callback.
This function is available since SDL_mixer 3.0.0.
