MVC_PlaySound()

OBJECTIVELYMVC_EXPORT void MVC_PlaySound

(

const Sound *

sound

)

Plays the specified Sound through the current SoundStage (if any).

Parameters

sound

The Sound to play.

Remarks

This is a convenience function, allowing Views to emit sounds in an ad-hoc way, without obtaining a reference to the SoundStage.
