You probably don't want strict raw I/O, as there would be considerable benefit in some sort of read-ahead buffering. What you want is an open/fcntl attribute which would instruct the kernel that you don't intend to do a seek, in which case it can free each buffer as soon as it has been fully read. -- Dave Mielke | 856 Grenon Avenue | I believe that the Bible is the Phone: 1-613-726-0014 | Ottawa, Ontario | Word of God.
