This is the main Wii IPC file that handles all incoming IPC calls and directs them
to the right function.
IPC basics (IOS' usage):
Return values for file handles: All IPC calls will generate a return value to 0x04,
in case of success they are
Open: DeviceID
Close: 0
Read: Bytes read
Write: Bytes written
Seek: Seek position
Ioctl: 0 (in addition to that there may be messages to the out buffers)
Ioctlv: 0 (in addition to that there may be messages to the out buffers)
They will also generate a true or false return for UpdateInterrupts() in WII_IPC.cpp.
