iswspace - test for whitespace wide character
int iswspace (wint_t wc);
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
The wide character class "space" always contains at least the space
character and the control characters '\f', '\n', '\r', '\t', '\v'.
The iswspace function returns non-zero if wc is a wide character
belonging to the wide character class "space". Otherwise it returns
ISO/ANSI C, UNIX98
The behaviour of iswspace depends on the LC_CTYPE category of the
