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.

SEE ALSO

       ispunct(3), iswctype(3)

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.
