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.

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 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.
