Corinna, That's by design, using of Chris' astute observations. As he once pointed out, INVALID_HANDLE_VALUE is the value returned in case of error but NULL is not a legal handle value either, as implied by CreateFile itself. Microsoft is using NULL handle values all the time. For the specific case of a NULL token handle, see SetThreadToken. So I do like Microsoft and I use NULL to denote the legitimate absence of a token. I also use INVALID_HANDLE_VALUE in the error case. Pierre
