@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");
