|
* History:
|
||
|
|
* Date By Reason
|
||
|
|
* ==== == ======
|
||
|
|

||
|
|
* 07/21/99 rodtoll Added settings confirm message to protocol.
|
||
|
|
* 07/22/99 rodtoll Added multiple reader/single writer guard to class

||
|
|
* 07/23/99 rodtoll Additional members for client/server and multicast
|
||
|
|
* 07/26/99 rodtoll Added support for new interfaces and access for DIRECTVOICESERVEROBJECT
|
||
|
|
* 08/25/99 rodtoll General Cleanup/Modifications to support new
|
||
|
|
* compression sub-system.
|
||
|
|
* Added parameter to the GetCompression Func
|
||
|
|
* 09/14/99 rodtoll Added new SetNotifyMask function
|
||
|
|
* rodtoll Updated Iniitalize parameters to take notification masks.
|

|
* 10/29/99 rodtoll Bug #113726 - Integrate Voxware Codecs, updating to use new
|
||
|
|
* pluggable codec architecture.
|
||
|
|
* 11/23/99 rodtoll Updated Initialize/SetNotifyMask so error checking behaviour is consistant
|
||
|
|
* 12/16/99 rodtoll Fix: Bug #122629 - Host migration broken in unusual configurations.
|
||
|
|
* Updated to use new algorithm described in dvprot.h
|
||
|
|
* - Generate and added host order IDs to player table messages
|
||
|
|
* - Added send of new hostmigrateleave message when shutting down and

|
||
|
|
* rodtoll Updated to use new callback semantics
|
||
|
|
* 03/29/2000 rodtoll Bug #30753 - Added volatile to the class definition
|
||
|
|
* 04/07/2000 rodtoll Bug #32179 - Prevent registration of > 1 interface
|
||
|
|
* rodtoll Updated to use no copy sends, so handles pooling frames to be sent, proper
|
||
|
|
* pulling of frames from pools and returns.
|
||
|
|
* 07/09/2000 rodtoll Added signature bytes
|
||
|
|
* 11/16/2000 rodtoll Bug #40587 - DPVOICE: Mixing server needs to use multi-processors
|
||
|
|
* 11/28/2000 rodtoll Bug #47333 - DPVOICE: Server controlled targetting - invalid targets are not removed automatically
|
||
