Subject: shared memory example

Can someone post a really small example of connecting to sysv shared
memory and accessing data there?

I'm trying to connect to some previously-created shmem and it's not
really working.

        key = SystemVIPC.ftok("/tmp/key_file", 1)
        shmem = SharedMemory.new(key)
        p shmem.size

I get: "No such file or directory - shmget(2) (Errno::ENOENT)" when
trying to get shmem.

Thanks in advance,
Joe
