NAME
 iswpunct - test for punctuation or symbolic wide character
SYNOPSIS
 #include <wctype.h>
 int iswpunct(wint_t wc);
DESCRIPTION
 The iswpunct() function is the wide-character equivalent of the is-
 punct(3) 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-charac-
 ter class "punct" is disjoint from the wide-character class "cntrl".
 Being a subclass of the wide-character class "graph", the wide-charac-
 ter class "punct" is disjoint from the wide-character class "space" and
 its subclass "blank".
RETURN VALUE
 The iswpunct() function returns nonzero if wc is a wide-character be-
 longing to the wide-character class "punct". Otherwise, it returns
 zero.

NOTES
 The behavior of iswpunct() depends on the LC_CTYPE category of the cur-
 rent locale.
 This function's name is a misnomer when dealing with Unicode charac-
 ters, because the wide-character class "punct" contains both punctua-
 tion characters and symbol (math, currency, etc.) characters.
