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 is-
       punct(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-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 nonzero if wc is a  wide-character  be-
       longing  to  the  wide-character  class "punct".  Otherwise, it returns
       zero.

CONFORMING TO
       POSIX.1-2001, POSIX.1-2008, C99.

NOTES
       The behavior of iswpunct() depends on the LC_CTYPE category of the cur-
       rent 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.
