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:

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