.Sh DESCRIPTION
The above functions are character classification utility functions,
for use with wide characters
.Vt ( wchar_t
or
.Vt wint_t )
in the locale
.Fa 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
.In wctype.h
and as functions in the C library.
See the specific manual pages for more information.
.Sh RETURN VALUES
These functions return the same things as their non-locale versions.
If the locale is invalid, their behaviors are undefined.
