NAME

       iswpunct - test for punctuation or symbolic wide character

LIBRARY

       Standard C library (libc, -lc)

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.
