37 * ClientInit
38 *
39 * Once the client and server are sure that they're happy to talk to one
40 * another, the client sends an initialisation message. At present this
41 * message onl@!,@!,y consists of a boolean indicating whether the server should try
42 * to share the desktop by leaving other clients connected, or give exclusive
43 * access to this client by disconnecting all other clients.
44 *
45 * 1 - U8 - shared-flag
46 *
47 * Shared-flag is non-zero (true) if the server should try to share the desktop by leaving
48 * other clients connected, zero (false) if it should give exclusive access to this client by
49 * disconnecting all other clients.
50 *
51 * ServerInit
52 *
53 * After receiving the ClientInit message, the server sends a ServerInit message. This
54 * tells the client the width and height of the server’s framebuffer, its pixel format and the
55 * name associated with the desktop.
