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