21 * NOTES
22 * o DPMSGCMD_ENUMSESSIONSREPLY & DPMSGCMD_ENUMSESSIONSREQUEST
23 * Have most fields understood, but not all. Everything seems to work.
24 * o DPMSGCMD_REQUESTNEWPLAYERID & DPMSGCMD_NEWPLAYERIDREPLY
25 * Barely work. This needs to be completed for sessions to start.
26 * o A small issue will be the fact that DirectX 6.1(ie. DirectPlay4)
27 * introduces a layer of functionality inside the DP objects which
28 * provide guaranteed protocol delivery. This is even if the native
29 * protocol, IPX or modem for instance, doesn't guarantee it. I'm going
30 * to leave this kind of implementation to as close to the end as
31 * possible. However, I will implement an abstraction layer, where
32 * possible, for this functionality. It will do nothing to start, but
33 * will require only the implementation of the guaranteness to give
34 * final implementation.
35 *
36 * TODO:
37 * - Implement mutual exclusion on object data for existing functions
38 * - Ensure that all dll stubs are present and the ordinals are correct
39 * - Addition of DirectX 7.0 functionality for direct play
40 * - Implement some WineLib test programs using sdk programs as a skeleton
41 * - Change RegEnumKeyEx enumeration pattern to allow error handling and to
42 * share registry implementation (or at least simplify).
43 * - Add in appropriate RegCloseKey calls for all the opening we're doing...
44 * - Fix all the buffer sizes for registry calls. They're off by one -
45 * but in a safe direction.
46 * - Fix race condition on interface destruction
47 * - Handles need to be correctly reference counted
48 * - Check if we need to deallocate any list objects when destroying
49 * a dplay interface
50 * - RunApplication process spawning needs to have correct syncronization.
51 * - Need to get inter lobby messages working.
52 * - Decypher dplay messages between applications and implement...
53 * - Need to implement lobby session spawning.
54 * - Improve footprint and realtime blocking by setting up a separate data share
55 * between lobby application and client since there can be multiple apps per
56 * client. Also get rid of offset dependency by making data offset independent
57 * somehow.
