I can not change cmd font with win32 api

[Gophear (M D)]

Hi guys,
I want to get console fonts with win32 apis but i couldnt
Here is my code:

func KernelGetConsoleHandle() (e syscall.Handle) {
	hwnd, _, _ := procGetConsoleWindow.Call()
	return syscall.Handle(hwnd)
}

func KernelGetConsoleFont(maximumWindows bool) *CONSOLE_FONT_INFOEX {
	in, err := syscall.GetStdHandle(syscall.STD_OUTPUT_HANDLE)
	if err != nil {
		fmt.Println("Could not get std handle")
		return nil
	}
	fmt.Println(in)

	var cfi CONSOLE_FONT_INFOEX
	cfi.Size = uint64(unsafe.Sizeof(cfi))

	mWindows := 0
	if maximumWindows {
		mWindows = 1
	}

	console, _, _ := procGetCurrentConsoleFontEx.Call(uintptr(in), uintptr(mWindows), uintptr(unsafe.Pointer(&cfi)))
	fmt.Println("cfi", cfi)
	if console == 0 {
		fmt.Println(syscall.Errno(GetLastError()))
	}
	fmt.Println("console", console)

	return &cfi
}

type CONSOLE_FONT_INFOEX struct {
	Size       uint64
	Font       uint32
	FontSize   COORD
	FontFamily uint64
	FontWeight uint64
	FaceName   [64]byte
}

type COORD struct {
	X int16
	Y int16
}

cfi := *win32.KernelGetConsoleFont(false)

I couldnt get filled cfi struct in KernelGetConsoleFont. Im not sure if this CONSOLE_FONT_INFOEX struct is correct either.
How can i solve this problem?
