iswpunct(3) Library Functions Manual iswpunct(3)
iswpunct - test for punctuation or symbolic wide character
Standard C library (libc, -lc)
#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.
For an explanation of the terms used in this section, see
attributes(7).

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.
