     iswblank(wint_t wc);

     int
     iswcntrl(wint_t wc);

     int
     iswdigit(wint_t wc);

     int
     iswgraph(wint_t wc);

     int
     iswlower(wint_t wc);

     int
     iswprint(wint_t wc);

     int
     iswpunct(wint_t wc);

     int
     iswspace(wint_t wc);

     int
     iswupper(wint_t wc);

     int
     iswxdigit(wint_t wc);

DESCRIPTION
     The functions are character classification utility functions, for use with wide characters (wchar_t or wint_t).  See the description of sin-
     glebyte classification functions, like isalnum(3), for details.

RETURN VALUES
     The functions return zero if the character tests false and return non-zero if the character tests true.

SEE ALSO

STANDARDS
     The functions conform to ISO/IEC 9899:1999 (``ISO C99'').

CAVEATS
     The argument to these functions must be WEOF or a valid wchar_t value with the current locale; otherwise, the result is undefined.
