DESCRIPTION
     The above functions are character classification utility functions, for
     use with wide characters (wchar_t or wint_t) in the locale loc.  They
     behave in the same way as the versions without the _l suffix, but use the
     specified locale rather than the global or per-thread locale.  These
     functions may be implemented as inline functions in <wctype.h> and as
     functions in the C library.  See the specific manual pages for more
     information.

RETURN VALUES
     These functions return the same things as their non-locale versions.  If
     the locale is invalid, their behaviors are undefined.

     extensions.
