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 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.

NOTES

       The behaviour 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.
