I'm a bit confused about how to interface with windows.h.

All I'm trying to do is retrieve some text from my clipboard to 
print it.

So far, I have this:

//----
import std.stdio;

import core.sys.windows.windows;

extern (Windows)
{
   HWND   GetClipboardOwner();
   BOOL   OpenClipboard(HWND hWndNewOwner);
   HANDLE GetClipboardData(UINT uFormat);
}

void main()
{
   HWND hWnd = GetClipboardOwner();

   if ( hWnd == null ) {stderr.writeln("Problem."); return;}
   if ( OpenClipboard(hWnd) == 0 ) {stderr.writeln("Problem 2."); 
return;}

   hWnd = cast(HWND)GetClipboardData(CF_TEXT);
}
//----

This works, but as you can see, I have to declare as "extern 
(Windows)" all the functions myself. Not pretty, but works I 
guess. I'm hitting a wall at "CF_TEXT" though: That's an enum.

Anyways...

Am I doing it wrong, or are is the amount of ported windows 
interface currently limited...

Kinda lost here (The fact that I'm also new to windows 
programming doesn't help...) :)

std.c.windows.windows is a very thin layer around the API. There are
better bindings here:
http://dsource.org/projects/bindings/wiki/WindowsApi

Take a look here, there are many examples of WinAPI programming:

Good deal. I was able to get it to work with that. Thanks.

Something like this:

HWND hwnd = ... // your window handle (or null)
if (OpenClipboard(hwnd)) {
   HGLOBAL data = GetClipboardData(CF_TEXT);
   if (data) {
     auto text = cast(wchar*)GlobalLock(data);
     writeln(to!string(text[0 .. wcslen(text)]));
     GlobalUnlock(data);
   }
}

You'll have to define GlobalLock/GlobalUnlock, and values for the 
various clipboard formats (CF_TEXT and co) are documented here: 
http://msdn.microsoft.com/en-gb/library/windows/desktop/ff729168%28v=vs.85%29.aspx

 I'm hitting a wall at "CF_TEXT" though: That's an enum.

enum : uint {
   CF_TEXT = 1,
   CF_BITMAP = 2, // and so on
}
