ISWPUNCT(3)                                         Linux Programmer's Manual                                        ISWPUNCT(3)



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 char-
       acter 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-charac-
       ter class "cntrl".

       Being  a subclass of the wide-character class "graph", the wide-character class "punct" is disjoint from the wide-charac-
       ter 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".   Other-
       wise 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" con-
       tains both punctuation characters and symbol (math, currency, etc.) characters.
