From what MSDN says, it returns SOCKET_ERROR and put an ERROR_CALL_NOT_IMPLEMENTED in 'errcode' parameter if it's unimplemented. You can add some tests for this. And it's better to have at least some basic parameter validation checks even for a stub.
Thanks, Zhiyi
Thanks for reviewing. I sent an updated version.
Kind regards, Bernhard
