WCTYPE(3)		 BSD Library Functions Manual		     WCTYPE(3)

NAME
     iswctype, wctype -- wide character	class functions

LIBRARY
     Standard C	Library	(libc, -lc)

SYNOPSIS
     #include <wctype.h>

     int
     iswctype(wint_t wc, wctype_t charclass);

     wctype_t
     wctype(const char *property);

DESCRIPTION
     The wctype() function returns a value of type wctype_t which represents
     the requested wide	character class	and may	be used	as the second argument
     for calls to iswctype().

     The following character class names are recognised:

	   alnum   cntrl   ideogram   print   space   xdigit
	   alpha   digit   lower      punct   special
	   blank   graph   phonogram  rune    upper

     The iswctype() function checks whether the	wide character wc is in	the
     character class charclass.

RETURN VALUES
     The iswctype() function returns non-zero if and only if wc	has the	prop-
     erty described by charclass, or charclass is zero.

     The wctype() function returns 0 if	property is invalid, otherwise it re-
     turns a value of type wctype_t that can be	used in	subsequent calls to
     iswctype().

EXAMPLES
     Reimplement iswalpha(3) in	terms of iswctype() and	wctype():

	   int
	   myiswalpha(wint_t wc)
	   {
		   return (iswctype(wc,	wctype("alpha")));
	   }

SEE ALSO
     ctype(3), nextwctype(3)

STANDARDS
     The iswctype() and	wctype() functions conform to IEEE Std 1003.1-2001
     ("POSIX.1").  The "ideogram", "phonogram",	"special", and "rune" charac-
     ter classes are extensions.

HISTORY
     The iswctype() and	wctype() functions first appeared in FreeBSD 5.0.
