I am asking more in terms of the posix event logging mechanism being implemented in Linux 2.5.x kernel. http://evlog.sourceforge.net/ How does the kevent mechanism of event notification and handling compare to this scheme? It appears to me that the Linux event logging merely supports logging of events in a different way that already exists via klogd. This is a more passive technique and requiring disk usage overheads in case of huge and rapid audits. On the other hand, kevent allows more active event registering and handling... What would be the pros and cons of both these techniques? Thanks. -Ram ==> Terry Lambert <tlambert2@mindspring.com>/11:23pm/May 9, 2002 <== [Ramkumar Chinchani wrote: [> Has the POSIX event standard implemeted in FreeBSD?
