## Declaration

func MusicPlayerIsPlaying(_ inPlayer: MusicPlayer, _ outIsPlaying: UnsafeMutablePointer<DarwinBoolean>) -> OSStatus

- `outIsPlaying`: On output true (nonzero) if playing, false (zero) if not playing.

## Return Value

## Discussion

Discussion If a music player has started playing and has not been explicitly stopped, the outIsPlaying value is true. Specifically, if the player’s music sequence has completed—so there is no more audible output—but the player has not been explicitly stopped, the outIsPlaying value is true and the music player’s time value continues to increase.
