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.
