SYNOPSIS



#include <wctype.h>



"int iswspace(wint_t "wc);

DESCRIPTION

The iswspace function is the wide-character equivalent of the isspace 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 ’\f’, ’\n’, ’\r’, ’\t’, ’\v’.

"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"

ISO/ANSI C, UNIX98

"SEE ALSO"

isspace(3), iswctype(3)
