     iswpunct, iswrune,	iswspace, iswspecial, iswupper,	iswxdigit -- wide
     character classification utilities

LIBRARY
     Standard C	Library	(libc, -lc)

SYNOPSIS
     #include <wctype.h>

     int
     iswalnum(wint_t wc);

     int
     iswalpha(wint_t wc);

     int
     iswascii(wint_t wc);

     int
     iswblank(wint_t wc);

     int
     iswcntrl(wint_t wc);

     int
     iswdigit(wint_t wc);

     int
     iswgraph(wint_t wc);

     int
     iswhexnumber(wint_t wc);

     int
     iswideogram(wint_t	wc);

     int
     iswlower(wint_t wc);

     int
     iswnumber(wint_t wc);

     int
     iswphonogram(wint_t wc);

     int
     iswprint(wint_t wc);

     int
     iswpunct(wint_t wc);

     int
     iswrune(wint_t wc);

     int
     iswspace(wint_t wc);

     int
     iswspecial(wint_t wc);

     int
     iswupper(wint_t wc);

     int
     iswxdigit(wint_t wc);

DESCRIPTION
     The above functions are character classification utility functions, for
     use with wide characters (wchar_t or wint_t).  See	the description	for
     the similarly-named single	byte 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
     isalnum(3), isalpha(3), isascii(3), isblank(3), iscntrl(3), isdigit(3),
     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)

STANDARDS
     These functions conform to	IEEE Std 1003.1-2001 (``POSIX.1''), except
     iswascii(), iswhexnumber(), iswideogram(),	iswnumber(), iswphonogram(),
     iswrune() and iswspecial(), which are FreeBSD extensions.

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