NEXTWCTYPE(3)						   BSD Library Functions Manual 					     NEXTWCTYPE(3)

NAME

     nextwctype, nextwctype_l -- iterate through character classes

LIBRARY

     Standard C Library (libc, -lc)

SYNOPSIS

     #include <wctype.h>

     wint_t
     nextwctype(wint_t ch, wctype_t wct);

     #include <xlocale.h>

     wint_t
     nextwctype_l(wint_t ch, wctype_t wct, locale_t loc);

DESCRIPTION

     The nextwctype() function determines the next character after ch that is a member of character class wct.	If ch is -1, the search begins at
     the first member of wct.

     While the nextwctype() function uses the current locale, the
      .Fn nextwctype_l function may be passed a locale directly. See xlocale(3) for more information.

RETURN VALUES

     The nextwctype() function returns the next character, or -1 if there are no more.

COMPATIBILITY

     This function is a non-standard FreeBSD extension and should not be used where the standard iswctype() function would suffice.

SEE ALSO

     wctype(3), xlocale(3)

HISTORY

     The nextwctype() function appeared in FreeBSD 5.4.

NAME

     iswctype, iswctype_l, wctype, wctype_l -- 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);

     #include <wctype.h>
     #include <xlocale.h>

     int
     iswctype_l(wint_t wc, wctype_t charclass, locale_t loc);

     wctype_t
     wctype_l(const char *property, locale_t loc);

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.

     Although the iswctype() and wctype() functions use the current locale, the iswctype_l() and wctype_l() functions may be passed locales
     directly. See xlocale(3) for more information.

RETURN VALUES

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

     The wctype() function returns 0 if property is invalid; otherwise, it returns 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), xlocale(3)

STANDARDS

     The iswctype() and wctype() functions conform to IEEE Std 1003.1-2001 (``POSIX.1'').  The ``ideogram'', ``phonogram'', ``special'', and
     ``rune'' character classes are extensions.

HISTORY

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