3.1.4.13 Remove Player from Group

When a higher-level entity indicates that the DirectPlay client SHOULD remove a player previously added to a group and the DirectPlay client has joined a game session, the DirectPlay client MUST format a DPSP_MSG_DELETEPLAYERFROMGROUP (section 2.2.26) packet with the PlayerID and GroupID fields set to the player ID and group ID to be added. If the Session.MulticastServer flag is set, the DirectPlay client MUST wrap the DPSP_MSG_DELETEPLAYERFROMGROUP message in a DPSP_MSG_ASK4MULTICAST message (section 2.2.14) and it MUST transmit the wrapped message to the game host. If the Session.MulticastServer flag is not set, the DirectPlay client MUST transmit the DPSP_MSG_DELETEPLAYERFROMGROUP message to each of the computers currently joined to the game session. There is no response expected to this message.
