NAME
iswspace - test for whitespace wide character
SYNOPSIS
#include <wctype.h>
I int iswspace(wint_t wc );
DESCRIPTION
The
R iswspace ()
function is the wide-character equivalent of the
isspace(3)
function.
It tests whether
wc is a wide character
belonging to the wide-character class "space".
The wide-character class "space" is disjoint from the wide-character class
"graph" and therefore also disjoint from its subclasses "alnum", "alpha",
"upper", "lower", "digit", "xdigit", "punct".
The wide-character class "space" contains the wide-character class "blank".
The wide-character class "space" always contains at least the space character
and the control characters '\, '\n', '\r', '\t', '\v'.
RETURN VALUE
The
R iswspace ()
function returns non-zero if wc is a wide character
belonging to the wide-character class "space".
Otherwise it returns zero.
CONFORMING TO
C99.
NOTES
The behavior of
R iswspace ()
depends on the
LC_CTYPE
category of the
current locale.
