iswpunct(3)             Library Functions Manual             iswpunct(3)

NAME         top

       iswpunct - test for punctuation or symbolic wide character

LIBRARY         top

       Standard C library (libc, -lc)

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.

HISTORY         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.
