iswspace - test for whitespace wide character
#include <wctype.h>
int iswspace(wint_t wc);
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 '\f', '\n', '\r', '\t', '\v'.
The
iswspace() function returns nonzero if
wc is a wide character
belonging to the wide-character class "space". Otherwise, it returns
zero.
