DESCRIPTION
The iswpunct function is the wide-character equivalent of the ispunct function. It tests whether wc is a wide character belonging to the wide character class "punct". The wide character class "punct" is a subclass of the wide character class "graph", and therefore also a subclass of the wide character class "print".
The wide character class "punct" is disjoint from the wide character class "alnum" and therefore also disjoint from its subclasses "alpha", "upper", "lower", "digit", "xdigit".
Being a subclass of the wide character class "print", the wide character class "punct" is disjoint from the wide character class "cntrl".
Being a subclass of the wide character class "graph", the wide character class "punct" is disjoint from the wide character class "space" and its subclass "blank".
"RETURN VALUE"
The iswpunct function returns non-zero if wc is a wide character belonging to the wide character class "punct". Otherwise it returns zero.
