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  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-charac-
     ter class "punct" is disjoint from the wide-character class "cntrl".
     Being a subclass of the wide-character class "graph", the  wide-charac-
     ter 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

     POSIX.1-2001, POSIX.1-2008, C99.

NOTES

     The behavior of iswpunct() depends on the LC_CTYPE category of the cur-
     rent locale.
     This function's name is a misnomer when dealing  with  Unicode  charac-
     ters,  because  the wide-character class "punct" contains both punctua-
     tion characters and symbol (math, currency, etc.) characters.
