sendfile has the following arguments:
        socket
        file descriptor
        offset
        length
        and some other guff.
So, you can use:
        void *addr = mmap(NULL, length, PROT_READ, MAP_FILE | MAP_SHARED,
                file descriptor, offset);
        send(socket, addr, length, 0);
