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-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.

CONFORMING TO
       POSIX.1-2001, POSIX.1-2008, 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.
