Section (3) iswpunct
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.
ATTRIBUTES
For an explanation of the terms used in this section, see attributes(7).

NOTES
The behavior of iswpunct
()
depends on the LC_CTYPE
category of the current locale.
This function_zsingle_quotesz_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.
