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 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  non-zero  if  wc  is  a  wide  character
       belonging  to  the  wide  character class "punct". Otherwise it returns
       zero.

CONFORMING TO
       ISO/ANSI C, UNIX98

SEE ALSO
       ispunct(3), iswctype(3)

NOTES
       The behaviour 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.
