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.

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.
