 - wide character class functions

LIBRARY

Lb libc

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 Vt 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
blankgraphphonogramruneupper

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

RETURN VALUES

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

The wctype ();
function returns 0 if Fa property is invalid, otherwise it returns a value of type Vt 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")));
}

STANDARDS

The iswctype ();
and wctype ();
functions conform to St -p1003.1-2001 . The ``ideogram '' ``phonogram '' ``special '' and ``rune '' character classes are extensions.
