SYNOPSIS


.In 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"
"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 property described by charclass, or charclass is zero.

The wctype function returns 0 if 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")));
}
