Socket privileged service "soc:P"

Command Header Description
0x00010084 InitializeSockets
0x00020000 FinalizeSockets
0x000300C2 SetNetworkOpt
0x00040040 CloseSocketsForProcess

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).

Socket module static buffers

This is the list of the known thread static buffers in use for SOC:u and the commands using those.

buffer ID commands
0 bind,connect
1 sendto_other,sendto
2 sendto
8 getnameinfo
9 setsockopt
10 poll
