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