iswpunct(3)
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(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.
CONFORMING TO
C99.
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.
