func MixAudioFormat(dst, src *uint8, format AudioFormat, len_ uint32, volume int) {
	_dst := (*C.Uint8)(unsafe.Pointer(dst))
	_src := (*C.Uint8)(unsafe.Pointer(src))
	_format := (C.SDL_AudioFormat)(format)
	_len := (C.Uint32)(len_)
	_volume := (C.int)(volume)
	C.SDL_MixAudioFormat(_dst, _src, _format, _len, _volume)
}

Example #2

File: audio.go Project: willemvds/sdl

	if len(dst) != len(src) {
		return errors.New("len(dst) != len(src)")

		(*C.Uint8)(unsafe.Pointer(&src[0])),
		C.SDL_AudioFormat(f),
		C.Uint32(len(dst)),
		C.int(vol),
	)

	return nil
