Hi! Sorry, i'm not native english language. I'm Andrea, i'm student in secondary high school in Catania, Italy. I want to study real time and networking meccanysm in xnu kernel.

If you can explain what you mean by "real time", we should be able to point you in the right direction. ---

So, does networking works with real time meccanysm?

Best regards, Andrea
