   Constructs a :class:`fmt::windows_error` object with the description
   of the form

   .. parsed-literal::
     *<message>*: *<system-message>*

   where *<message>* is the formatted message and *<system-message>* is the
   system message corresponding to the error code.
   *error_code* is a Windows error code as given by ``GetLastError``.
   If *error_code* is not a valid error code such as -1, the system message
   will look like "error -1".

   **Example**::

     // This throws a windows_error with the description
     //   cannot open file 'madeup': The system cannot find the file specified.
     // or similar (system message may vary).
     const char *filename = "madeup";
     LPOFSTRUCT of = LPOFSTRUCT();
     HFILE file = OpenFile(filename, &of, OF_READ);
     if (file == HFILE_ERROR) {
       throw fmt::windows_error(GetLastError(),
                                "cannot open file '{}'", filename);
     }
