Halt playing of the music stream.
Defined in <SDL_mixer.h>
int Mix_HaltMusic(void);
(int) Returns zero, regardless of whether any music was halted.
This will stop further playback of music until a new music object is started there.
Any halted music will call any callback specified by Mix_HookMusicFinished() before this function returns.
This function is available since SDL_mixer 2.0.0.
