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 char­
       acter 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  Uni­
       code  characters, because the wide character class "punct"
       contains both punctuation  characters  and  symbol  (math,
       currency, etc.) characters.
