I understand why others talk about RTAI and RTLinux forking, http://www.tux.org/pub/devel/LINUX-LAB/RTAPPS/paolo/myrtlinux-0.6.README > I actually _do_ my research. Me too. I've been here before, I was one of about 8 people who actually knew that AT&T should have won the BSD lawsuit because I diffed the code. And you can't diff it with a perl script, that simply doesn't work. The only real ways that I know of are a) have a human do it, function by function b) compile the code to an expression tree and then diff the expression trees. -- --- Larry McVoy lm at bitmover.com http://www.bitmover.com/lm
