The IDirectPlay4::DestroyGroup method deletes a group from the session. The ID belonging to this group will not be reused during the current session.
HRESULT DestroyGroup( DPID idGroup );
Returns DP_OK if successful, or one of the following error messages otherwise:
| DPERR_CONNECTIONLOST | 
| DPERR_INVALIDGROUP | 
| DPERR_INVALIDOBJECT | 
| DPERR_INVALIDPARAMS | 
| DPERR_INVALIDPLAYER | 
It is not necessary to empty a group before deleting it. The individual players belonging to the group are not destroyed. This method will generate a DPMSG_DELETEPLAYERFROMGROUP system message for each player in the group, and then a DPMSG_DESTROYPLAYERORGROUP system message. For a list of system messages, see Using System Messages.
Any application can destroy any group even if the group was not created locally.
