dwPacketType (4 bytes): A 32-bit field that contains the packet type.

Value	Meaning
DN_MSG_INTERNAL_UPDATE_INFO 0x000000DB	Update info response from a host/server to a peer/client.

dwPacketContext (4 bytes): A 32-bit field that contains the context value passed in for this operation. This value MUST be passed back exactly as it was passed in with DN_REQ_UPDATE_INFO (section 2.2.5.1).

dpnid (4 bytes): A 32-bit field that contains the identifier for the peer/client that was updated. For more information, see section 2.2.7.

dwVersion (4 bytes): A 32-bit integer that specifies the current name table version.

dwVersionNotUsed (4 bytes): Not used.

dwInfoFlags (4 bytes): A 32-bit field that contains the passed flags that were updated.

Value	Meaning
DPNINFO_NAME 0x00000001	Indicates whether a name is included with this packet.
DPNINFO_DATA 0x00000002	Indicates whether data is included with this packet.

dwNameOffset (4 bytes): A 32-bit field that contains the offset from the end of dwPacketType of the name field for the DPNID. If dwNameOffset is 0, the packet does not include name data.

dwNameSize (4 bytes): A 32-bit field that contains the size, in bytes, of the data in the name field. If dwNameOffset is set to 0, dwNameSize SHOULD also be 0. If dwNameOffset is not 0, dwNameSize SHOULD also not be 0.

dwDataOffset (4 bytes): A 32-bit field that contains the offset from the end of dwPacketType of the data field. If dwDataOffset is 0, the packet does not include application data.

dwDataSize (4 bytes): A 32-bit field that contains the size, in bytes, of the data field. If dwDataOffset is set to 0, dwDataSize SHOULD also be 0. If dwDataOffset is not 0, dwDataSize SHOULD also not be 0.

dpnidRequesting (4 bytes): A 32-bit field that contains the identifier for the player that requested that this information be updated. For more information, see section 2.2.7.

data (variable): A variable-length field that contains a byte array that provides the application data. This field's position is determined by dwDataOffset and the size stated in dwDataSize.

name (variable): A variable-length field that contains a zero-terminated wide character array that specifies the player's name. This field's position is determined by dwNameOffset and the size stated in dwNameSize.
