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

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.
