The MAKEWORD(2,2) parameter of WSAStartup makes a request for version 2.2 of Winsock on the system, and sets the passed version as the highest version of Windows Sockets support that the caller can use. The WSADATA structure contains information about the Windows Sockets implementation. The WSAStartup function is called to initiate use of WS2_32.dll. FUdpSocketBuilder: Failed to subscribe UdpMessageMulticastSocket to multicast group 230.0.0.1 on interface 0.0.0.0 FUdpSocketBuilder: Failed to create and initialize socket UdpMessageMulticastSocket (last error: 0) LogUdpMessaging: Warning: StartTransport failed to create multicast socket on 0.0.0.0:0, joined to 230.0.0.1:6666 with TTL 1.
However, this functionality was not available for Windows 95, Windows 98, and Windows Me. With the release of Winsock 2, overlapped I/O can still be used with the functions ReadFile() and WriteFile() under Windows NT and Windows 2000. Printf("WSAStartup failed: %d\n", iResult) As a result, the overlapped I/O model is now available on all Windows platforms that feature Winsock 2. IResult = WSAStartup(MAKEWORD(2,2), &wsaData) the only way to fix it on the as of now new a6 7310 notebook is as follows- TYPE 'device manager' into windows (10) search bar- SCROLL to 'network adapters'-SELECT 'realtek rtl8723be''''' wifi adapter' (which is the route cause of the problem)-RIGHT CLICK and 'update drivers' use the internet to find and auto install option and thats it. WSADATA wsaData Ĭall WSAStartup and return its value as an integer and check for errors. This also makes certain that Winsock is supported on the system.Ĭreate a WSADATA object called wsaData. All processes (applications or DLLs) that call Winsock functions must initialize the use of the Windows Sockets DLL before making other Winsock functions calls.
