@trusted string sysErrorString(DWORD errCode, int langId = LANG_NEUTRAL, int subLangId = SUBLANG_DEFAULT);
  Query the text for a Windows error code, as returned by GetLastError, as a D string.
class WindowsException: object.Exception;
  Thrown if errors that set GetLastError occur.
  final @property DWORD code();
    GetLastError's return value.
@safe T wenforce(T, S)(T value, lazy S msg = null, string file = __FILE__, size_t line = __LINE__)
if (isSomeString!S);
  If !!value is true, value is returned. Otherwise, new WindowsException(GetLastError(), msg) is thrown. WindowsException assumes that the last operation set GetLastError() appropriately.

  Example:

      wenforce(DeleteFileA("junk.tmp"), "DeleteFile failed");
