RedHat 9 (Linux i386) - man page for iswpunct (redhat section 3)

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 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.

CONFORMING TO
       ISO/ANSI C, UNIX98

SEE ALSO
       ispunct(3), iswctype(3)

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.
