The
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 aq\faq, aq\naq, aq\raq, aq\taq, aq\vaq.
RETURN VALUE
The
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
iswspace()
depends on the
LC_CTYPE
category of the
current locale.
