NAME

6       iswpunct - test for punctuation or symbolic wide character
7

SYNOPSIS

9       #include <wctype.h>
10
11       int iswpunct(wint_t wc);
12

DESCRIPTION

14       The  iswpunct()  function  is  the  wide-character  equivalent  of  the
15       ispunct(3) function.  It tests whether wc is a wide character belonging
16       to the wide-character class "punct".
17
18       The  wide-character  class  "punct" is a subclass of the wide-character
19       class "graph", and therefore also  a  subclass  of  the  wide-character
20       class "print".
21
22       The  wide-character  class  "punct" is disjoint from the wide-character
23       class "alnum" and therefore also disjoint from its subclasses  "alpha",
24       "upper", "lower", "digit", "xdigit".
25
26       Being  a subclass of the wide-character class "print", the wide-charac‐
27       ter class "punct" is disjoint from the wide-character class "cntrl".
28
29       Being a subclass of the wide-character class "graph", the  wide-charac‐
30       ter class "punct" is disjoint from the wide-character class "space" and
31       its subclass "blank".
32

RETURN VALUE

34       The iswpunct() function returns non-zero  if  wc  is  a  wide-character
35       belonging  to  the  wide-character class "punct".  Otherwise it returns
36       zero.

NOTES

42       The behavior of iswpunct() depends on the LC_CTYPE category of the cur‐
43       rent locale.
44
45       This  function's  name  is a misnomer when dealing with Unicode charac‐
46       ters, because the wide-character class "punct" contains  both  punctua‐
47       tion characters and symbol (math, currency, etc.) characters.
