Hello d06901f0801071053p9dbefc4ga281c1f0e95ebe05@mail.gmail.com>ab83bf010801071005g6f94cf6auebd487525c5f54a4@mail.gmail.com>Panagiotis,
Wouldn't it have been easier to just use an auto binding generator (SWIG, tolua, etc)?

SWIG would happily have accepted

bool d06901f0801071053p9dbefc4ga281c1f0e95ebe05@mail.gmail.com>ab83bf010801071005g6f94cf6auebd487525c5f54a4@mail.gmail.com>validate(int);
bool isalnum(int);
bool isalpha(int);
....
and similar

Just a though,
