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.

SDL_LockAudio
SDL_UnlockAudioDevice
