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 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.

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.
