Since most of FuncW require not only the pointer but length as well, you
usually call them like this:

  wchar[] foo = "some string";
  FuncW(foo.ptr, foo.length);

To get a string from a function you need a buffer:

  auto buf = new wchar[MAX_PATH];
  buf.length = GetModuleFileNameW(h, buf.ptr, buf.length);
