SDL_UnlockAudio
This function is a legacy means of unlocking the audio device. New programs might want to use SDL_UnlockAudioDevice() instead.
Syntax
void SDL_UnlockAudio(void)
Code Examples
void MyAudioCallback(void *userdata, Uint8* stream, int len)
{
printf("The audio callback is running!\n");
SDL_memset(stream, 0, len); // just silence.
printf("The audio callback is done!\n");
}
// don't lock for 2 seconds at a time in real life, please.
SDL_Delay(2000); // callback runs for 2 seconds.
SDL_LockAudio();
printf("The audio callback can't be running right now!\n");
SDL_Delay(2000); // callback doesn't run for 2 seconds.
printf("Ok, unlocking!\n");
SDL_UnlockAudio();
SDL_Delay(2000); // callback runs for 2 seconds.
Remarks
This function is equivalent to calling
SDL_UnlockAudioDevice(1);
and is only useful if you used the legacy SDL_OpenAudio() function.
