@ -399,11 +399,15 @@ Raised when an \keyword{assert} statement fails.
\begin{excdesc}{WindowsError}
Raised when a Windows-specific error occurs or when the error number
does not correspond to an \cdata{errno} value. The
\member{errno} and \member{strerror} values are created from the
\member{winerror} and \member{strerror} values are created from the
return values of the \cfunction{GetLastError()} and
\cfunction{FormatMessage()} functions from the Windows Platform API.
The \member{errno} value maps the \member{winerror} value to
corresponding \code{errno.h} values.
This is a subclass of \exception{OSError}.

codes into \member{errno}]{2.5}
