        The function tolower_l() behaves identically to tolower(), except
        instead of operating in the current locale, it operates in the locale

 RETURN VALUES
        On successful completion, tolower() returns the lower-case letter
        corresponding to the argument passed. Otherwise, it returns the
        argument unchanged.
