DESCRIPTION
     The above functions are character classification utility functions, for
     use with wide characters (wchart or wintt).  See the description for
     the similarly-named single byte classification functions (like
     isalnum(3)), for details.

     Extended locale versions of these functions are documented in
     iswalnuml(3).  See xlocale(3) for more information.

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

SEE ALSO

     isgraph(3), ishexnumber(3), isideogram(3), islower(3), isnumber(3),
     isphonogram(3), isprint(3), ispunct(3), isrune(3), isspace(3),
     isspecial(3), isupper(3), isxdigit(3), wctype(3), iswalnuml(3)

STANDARDS
     These functions conform to IEEE Std 1003.1-2001 (``POSIX.1''), except
     iisswwaasscciiii(), iisswwhheexxnnuummbbeerr(), iisswwiiddeeooggrraamm(), iisswwnnuummbbeerr(), iisswwpphhoonnooggrraamm(),
     iisswwrruunnee() and iisswwssppeecciiaall(), which are FreeBSD extensions.

CCAAVVEEAATTSS
     The result of these functions is undefined unless the argument is WEOF or
     a valid wchart value for the current locale.
