Golang Mix_OpenAudio Examples

Example #1

File: sdl_mixer.go Project: hybridgroup/go-sdl2

func OpenAudio(frequency int, format uint16, channels, chunksize int) bool {
	_frequency := (C.int)(frequency)
	_format := (C.Uint16)(format)
	_channels := (C.int)(channels)
	_chunksize := (C.int)(chunksize)
	return int(C.Mix_OpenAudio(_frequency, _format, _channels, _chunksize)) == 0
}

Example #2

File: mixer.go Project: beoran/fungo

// Open the mixer with a certain audio format 
func OpenMixer(frequency int, format uint16, channels int, chunksize int) (bool) {     
  res := (int(C.Mix_OpenAudio(C.int(frequency),

  ok  := (res == 0)
  MixerOpened  = ok 	     
  return ok
}

Example #3

File: sdl_mixer.go Project: 4gophers/go-sdl2

	if C.Mix_OpenAudio(_frequency, _format, _channels, _chunksize) < 0 {
		return sdl.GetError()
	}

Example #5

File: mixer.go Project: paul-lalonde/Go-SDL

// initialization errors.
