If you use overlapped, it will never return WSAEWOULDBLOCK. Only non-error return values for overlapped are, TRUE or FALSE with GetLastError() returning WSA_IO_PENDING.

That error only shows up with WSAEventSelect(), WSAAsyncSelect(), select(). And it means that no data was moved to/copied from socket buffers (either socket buffer was empty or full).
