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

       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" contains both
       punctuation characters and symbol (math, currency, etc.) characters.
