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(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  sub-
       class 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
       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.
