Описание (Description)
The iswblank() function is the wide-character equivalent of the
isblank(3) function. It tests whether wc is a wide character
belonging to the wide-character class "blank".
The wide-character class "blank" is a subclass of the wide-
character class "space".
Being a subclass of the wide-character class "space", the wide-
character class "blank" 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 "blank" always contains at least the
space character and the control character '\t'.
Возвращаемое значение (Return value)
The iswblank() function returns nonzero if wc is a wide character
belonging to the wide-character class "blank". Otherwise, it
returns zero.
