You have to use a variable because accept may write to it (?). >From the man page: The addrlen is a value-result parameter; it should initially contain the amount of space pointed to by addr; on return it will contain the actual length (in bytes) of the address returned. It doesn't make sense to cast the results of sizeof to a pointer. Mike -- Hi William. To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-hackers" in the body of the message
