Function MusicPlayerIsPlaying 

pub unsafe extern "C-unwind" fn MusicPlayerIsPlaying(
    in_player: MusicPlayer,
    out_is_playing: NonNull<u8>,
) -> i32

Available on crate feature MusicPlayer only.

Returns the playing state of the player. “Is it playing?”

This call returns a non-zero value in outIsPlaying if the player has been started and not stopped. It may have “played” past the events of the attached MusicSequence, but it is still considered to be playing (and its time value increasing) until it is explicitly stopped

Parameter inPlayer: the player

Parameter outIsPlaying: false if not, true (non-zero) if is playing
