54 * IDirectPlayLobby {1,2,3} implementation structure
56 * The philosophy behind this extra pointer derefernce is that I wanted to
57 * have the same structure for all types of objects without having to do
58 * alot of casting. I also only wanted to implement an interface in the
59 * object it was "released" with IUnknown interface being implemented in the 1 version.
60 * Of course, with these new interfaces comes the data required to keep the state required
61 * by these interfaces. So, basically, the pointers contain the data associated with
62 * a release. If you use the data associated with release 3 in a release 2 object, you'll
63 * get a run time trap, as that won't have any data.

247 * * The set of interfaces accessible on an object through
248 * IUnknown::QueryInterface must be static, not dynamic. This means that
249 * if a call to QueryInterface for a pointer to a specified interface
250 * succeeds the first time, it must succeed again, and if it fails the
251 * first time, it must fail on all subsequent queries.
252 * * It must be symmetric ~W if a client holds a pointer to an interface on
253 * an object, and queries for that interface, the call must succeed.
254 * * It must be reflexive ~W if a client holding a pointer to one interface
255 * queries successfully for another, a query through the obtained pointer
256 * for the first interface must succeed.
257 * * It must be transitive ~W if a client holding a pointer to one interface
258 * queries successfully for a second, and through that pointer queries
259 * successfully for a third interface, a query for the first interface
260 * through the pointer for the third interface must succeed.
