iswpunct3
Test for punctuation or symbolic wide character
Usage
#include <wctype.h>
int iswpunct(wint_t wc);
Library
Standard C library (libc, -lc)
Overview
The iswpunct() function is the wide-character equivalent of the ispunct(3) 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 nonzero if wc is a wide-character belonging to the wide-character class "punct". Otherwise, it returns zero.

Notes
The behavior 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.
