ISWPUNCT(3)               Linux Programmer's Manual              ISWPUNCT(3)

NAME         top

       iswpunct - test for punctuation or symbolic wide character

SYNOPSIS         top

       #include <wctype.h>
       int iswpunct(wint_t wc);

DESCRIPTION         top

       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         top

       The iswpunct() function returns nonzero if wc is a wide-character
       belonging to the wide-character class "punct".  Otherwise, it returns
       zero.

CONFORMING TO         top

NOTES         top

       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.
