)
 
func main() {
    sdl.Init(sdl.INIT_EVERYTHING);
    defer sdl.Quit()
 
    window, _ := sdl.CreateWindow("main", 0, 0, 320, 240, sdl.WINDOW_SHOWN)
    defer window.Destroy()
 
    renderer, _ := sdl.CreateRenderer(window, -1, sdl.RENDERER_ACCELERATED)
    defer renderer.Destroy()

    data, _ := ioutil.ReadFile("main.bmp")
    rwops, _ := sdl.RWFromMem(data)
    bmp, _ := sdl.LoadBMPRW(rwops, true)
    t, _ := renderer.CreateTextureFromSurface(bmp)
    defer bmp.Free()
    defer t.Destroy()
 
    renderer.Clear()
    renderer.Copy(t, nil, nil)
    renderer.Present()
 
    sdl.Delay(3000)
