2-13 Output 0x30-byte structure.

Output structure[edit]

Offset Size Description
0x0 0x4 u32 status
0x4 0x4 Unknown u32. Official user-processes check for values: 0x0, 0x1, and non-zero.
0x8 0x2 u16 NetworkNodeID for this device. This is the broadcast alias when connected as a spectator.
0xA 0x2 u16, changed_nodes. This is a bitmask of the nodes that changed and triggered the update.
0xC 0x20 u16 nodes[16]. Array of NetworkNodeIds, the values inside this array is what's passed to NWMUDS:GetNodeInformation.
0x2C 0x1 u8 total_nodes.
0x2D 0x1 u8 max_nodes, originally from the NetworkStruct.
0x2E 0x2 u16 node_bitmask. This is a bitmask of NetworkNodeIDs: bit0 for NetworkNodeID 0x1(host), bit1 for NetworkNodeID 0x2(first original client), and so on.

Right after initializing, this structure is all-zero except for the status which is value 0x3.

Status values[edit]

Type Description
0x3 Not connected to any network as a host/client, or just initialized.
0x6 Connected to a network as a host.
0x9 Connected to a network as a client.
0xA Connected to a network as a spectator.
0xB For this value official user-processes use NWMUDS:UpdateNetworkAttribute to clear attributes bitmask 0x6.


This is mainly used when the event handle from NWMUDS:Initialize is signaled. This is also used before using NWMUDS:Bind. For certain user-processes this may be used during NWMUDS initialization as well.

The event is not signaled when using NWMUDS:DestroyNetwork or NWMUDS:DisconnectNetwork. However the event does get signaled when creating or connecting to a network.
