PROLOG

       This  manual page is part of the POSIX Programmer's Manual.  The Linux implementation of this interface may differ (consult the correspond-
       ing Linux manual page for details of Linux behavior), or the interface may not be implemented on Linux.

NAME

       wctype - define character class

SYNOPSIS

       #include <wctype.h>

       wctype_t wctype(const char *property);

DESCRIPTION

       The wctype() function is defined for valid character class names as defined in the current locale. The property argument is a string  iden-
       tifying	a  generic  character  class for which codeset-specific type information is required. The following character class names shall be
       defined in all locales:

				  alnum 		       digit			    punct
				  alpha 		       graph			    space
				  blank 		       lower			    upper
				  cntrl 		       print			    xdigit

       Additional character class names defined in the locale definition file (category LC_CTYPE ) can also be specified.

       The function shall return a value of type wctype_t, which can be used as the second  argument  to  subsequent  calls  of  iswctype().   The
       wctype()  function  shall determine values of wctype_t according to the rules of the coded character set defined by character type informa-
       tion in the program's locale (category LC_CTYPE ). The values returned by wctype() shall be valid until a call to setlocale() that modifies
       the category LC_CTYPE .

RETURN VALUE

       The wctype() function shall return 0 if the given character class name is not valid for the current locale (category LC_CTYPE ); otherwise,
       it shall return an object of type wctype_t that can be used in calls to iswctype().

NAME

       wctype - define character class

SYNOPSIS

       #include <wchar.h>

       wctype_t wctype(const char *charclass);

DESCRIPTION

       The  wctype() function is defined for valid character class names as defined in the current locale. The charclass is a string identifying a
       generic character class for which codeset-specific type information is required. The following character class names  are  defined  in  all
       locales:

       alnum		    alpha		  blank
       cntrl		    digit		  graph
       lower		    print		  punct
       space		    upper		  xdigit

       Additional character class names defined in the locale definition file (category LC_CTYPE) can also be specified.

       The  function  returns  a  value  of  type wctype_t, which can be used as the second argument to subsequent calls of iswctype(3C). wctype()
       determines values of wctype_t according to the rules of the coded character set defined by character  type  information	in  the  program's
       locale (category LC_CTYPE). The values returned by wctype() are valid until a call to setlocale(3C) that modifies the category LC_CTYPE.

RETURN VALUES

       The  wctype()  function	returns  0 if the given character class name is not valid for the current locale (category LC_CTYPE); otherwise it
       returns an object of type wctype_t that can be used in calls to iswctype().
