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 works. 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 guarantee 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 synchronization.
51  * - Need to get inter lobby messages working.
52  * - Decipher 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.
