NAME

6       iswpunct - test for a punctuation wide-character code
7

SYNOPSIS

9       #include <wctype.h>
10
11       int iswpunct(wint_t wc);
12
13

DESCRIPTION

15       The  iswpunct() function shall test whether wc is a wide-character code
16       representing a character  of  class  punct  in  the  program's  current
17       locale;  see the Base Definitions volume of IEEE Std 1003.1-2001, Chap‐
18       ter 7, Locale.
19
20       The wc argument is a wint_t, the value of which the  application  shall
21       ensure  is  a wide-character code corresponding to a valid character in
22       the current locale, or equal to the value of the  macro  WEOF.  If  the
23       argument has any other value, the behavior is undefined.
24

RETURN VALUE

26       The  iswpunct()  function  shall return non-zero if wc is a punctuation
27       wide-character code; otherwise, it shall return 0.
