iswpunct - test for punctuation or symbolic wide character
#include <wctype.h>
int iswpunct(wint_t wc);
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".
The iswpunct() function returns nonzero if wc is a wide-character belonging to
the wide-character class "punct". Otherwise it returns zero.
C99.
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.
