POPIS / INSTRUKCE

The iswxdigit function is the wide-character equivalent of the isxdigit function. It tests whether wc is a wide character belonging to the wide character class "xdigit". The wide character class "xdigit" is a subclass of the wide character class "alnum", and therefore also a subclass of the wide character class "graph" and of the wide character class "print". Being a subclass of the wide character class "print", the wide character class "xdigit" is disjoint from the wide character class "cntrl". Being a subclass of the wide character class "graph", the wide character class "xdigit" is disjoint from the wide character class "space" and its subclass "blank". Being a subclass of the wide character class "alnum", the wide character class "xdigit" is disjoint from the wide character class "punct". The wide character class "xdigit" always contains at least the letters 'A' to 'F', 'a' to 'f' and the digits '0' to '9'.

NÁVRATOVÁ HODNOTA

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