Halt the music stream after fading it out for a specified time.
int Mix_FadeOutMusic(int ms);
|ms||number of milliseconds to fade before halting the channel.|
Returns non-zero if music was scheduled to fade, zero otherwise. If no music is currently playing, this returns zero.
This will begin the music fading from its current volume to silence over
ms milliseconds. After that time, the music is halted.
Any halted music will call any callback specified by Mix_HookMusicFinished() once the halt occurs.
Fading music will change it's volume progressively, as if Mix_VolumeMusic() was called on it (which is to say: you probably shouldn't call Mix_VolumeMusic() on a fading channel).
Note that this function does not block for the number of milliseconds requested; it just schedules the music to fade and notes the time for the mixer to manage later, and returns immediately.
This function is available since SDL_mixer 2.0.0.
