If the two programs are running on the same client, then the answer is (and always has been), that O_APPEND will work correctly. If the two programs are not both running on the same client, then as far as NFS is concerned, the question is nonsensical: there is no support for two clients writing to the same file at the same time. Applications that wish to do so have to use an appropriate file locking scheme. Trond -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
