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 ispunct(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-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  nonzero if wc is a wide-character belonging to the wide-character class "punct".  Otherwise, it returns
       zero.

NOTES
       The behavior of iswpunct() depends on the LC_CTYPE category of the current locale.

       This function's name is a misnomer when dealing with Unicode characters, because the wide-character class "punct" contains both punctuation
       characters and symbol (math, currency, etc.) characters.
