POPIS / INSTRUKCE

The iswblank function is the wide-character equivalent of the isblank 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'.

NÁVRATOVÁ HODNOTA

The iswblank function returns non-zero if wc is a wide character belonging to the wide character class "blank". Otherwise it returns zero.

ODPOVÍDAJÍCÍ

This function is a GNU extension.
