Re: shared memory

["Rafael Sisto" <rafael.sisto@gmail.com>]

Thank you for the quick answer, but It's a college project, and I must
share user level memory. I also must build my own system calls...
But I can look what is already done and make something similar. Do you
think shmget would do? Does it share user level memory?

greetings!
