Message-ID: <ee3dc96c0712161201y34a3e3e0t601ab4fa73d002c@mail.gmail.com> Date: Sun, 16 Dec 2007 17:01:17 -0300 From: "Rafael Sisto" <rafael.sisto@...il.com> To: "Luciano Rocha" <luciano@...otux.com>, "Rafael Sisto" <rafael.sisto@...il.com>, "Linux kernel" <linux-kernel@...r.kernel.org> Subject: Re: shared memory 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!
