Socket privileged service "soc:P"
| Command Header | Description |
|---|---|
| 0x00010084 | InitializeSockets |
| 0x00020000 | FinalizeSockets |
| 0x000300C2 | SetNetworkOpt |

struct sockaddr
| Offset | Size | Description |
|---|---|---|
| 0x0 | 0x1 | Total size of the entire sockaddr buffer. |
| 0x1 | 0x1 | u8 sa_family |
| 0x2 | sockaddr_totalsize-0x2 | sa_data[] |
The total buffer size is 0x8, for family AF_INET value 2. AF_INET6 seems to be value 23, the total sockaddr size for this is 0x1C. The max sockaddr buffer size which the socket module can handle is size 0x1C.
These socket services(and defines/structures) seem to be based on the Wii sockets?
Socket module errors
| Error | Description |
|---|---|
| 0xC8A0700B | SOCU:InitializeSockets returns this when the specified PID was already used with SOCU:InitializeSockets(since the PID was found in SOC module state table). |
| 0xD860700A | SOCU:InitializeSockets returns this when the PID table is already full(32 processes max). |
