ISWPUNCT(3) Linux Programmer's Manual ISWPUNCT(3)NAMEiswpunct - 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() 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 charac‐
ter class "punct" is disjoint from the wide character class "cntrl".
Being a subclass of the wide character class "graph", the wide charac‐
ter class "punct" is disjoint from the wide character class "space" and
its subclass "blank".
RETURN VALUE
The iswpunct() function returns non-zero if wc is a wide character
belonging to the wide character class "punct". Otherwise it returns
zero.
CONFORMING TO
C99.
SEE ALSOispunct(3), iswctype(3)NOTES
The behaviour of iswpunct() depends on the LC_CTYPE category of the
current locale.
This function's name is a misnomer when dealing with Unicode charac‐
ters, because the wide character class "punct" contains both punctua‐
tion characters and symbol (math, currency, etc.) characters.
