NAME
       SDL_LockAudio - Lock out the callback function


SYNOPSIS
       #include "SDL.h"

       void SDL_LockAudio(void)


DESCRIPTION
       The lock manipulated by these functions protects the callback function.
       During a LockAudio period, you can  be  guaranteed  that  the  callback
       function  is  not running. Do not call these from the callback function
       or you will cause deadlock.
