Are you talking about the flag CTLFLAG_RW ? I'm using req->oldptr == NULL and req->newptr != NULL to add a new element into a kernel table.... and I plan to use req->oldptr & req->newptr != NULL to show the elements of the table... could I instead use CTLFLAG_RO and keep the same access to the buffers ? Excuse me because it might be a foolish question, but I don't know how these flags can affect the behaviour of the sysctl operations... Anyway, I'm going to try different options today :) Thanks! -- JFRH. To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-net" in the body of the message
