SDL_MixAudio

This function is a legacy means of mixing audio.

void SDL_MixAudio(Uint8 * dst, const Uint8 * src,
                  Uint32 len, int volume);

Function Parameters

Uint8 *	dst	the destination for the mixed audio.
const Uint8 *	src	the source audio buffer to be mixed.

int	volume	ranges from 0 - 128, and should be set to SDL_MIX_MAXVOLUME for full audio volume.
