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
       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  non-zero  if  wc  is a wide character
       belonging to the wide character class  "punct".  Otherwise  it  returns
       zero.

NOTES

       The  behaviour  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.
