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