Имя (Name)
iswspace - test for whitespace wide character
Синопсис (Synopsis)
#include <wctype.h>
int iswspace(wint_t wc);
Описание (Description)
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'.
Возвращаемое значение (Return value)
The iswspace() function returns nonzero if wc is a wide character
belonging to the wide-character class "space". Otherwise, it
returns zero.
