* History:

* Date By Reason
|
|
* ==== == ======
|
|
* 07/23/99 rodtoll Modified from dvdptran.h
|
|
* 08/03/99 rodtoll Modified to conform to new base class and minor fixes
|
|
* for dplay integration.
|
|
* 11/23/99 rodtoll Split CheckForValid into Group and Player
|
|
* 01/14/2000 rodtoll Renamed SendToID to SendToIDS and updated parameter list
|
|
* to accept multiple targets.
|
|
* rodtoll Added GetNumPlayers call
|
|
* 03/28/2000 rodtoll Moved nametable from here to upper level classes
|
|
* rodtoll Removed uneeded functions/members
|
|
* 04/07/2000 rodtoll Updated to support new DP <--> DPV interface
|
|
* rodtoll Updated to support no copy sends
|
|
* rodtoll Bug #32179 - Prevent multiple client/server registrations on transport
|
|
* 06/21/2000 rodtoll Bug #36820 - Host migrates to wrong client when client/server are on same interface
|
|
* Condition exists where host sends leave message, client attempts to start new host
|
|
* which fails because old host still registered. Now deregistering is two step
|
|
* process DisableReceiveHook then DestroyTransport.
