The following example shows how an application can use a sub-connection explicitly via an RSubConnection instance, and tie an RSocket to the sub-connection that has had its properties set. The socket is connected over the sub-connection in this case (if the underlying technology allows this).
RSocketServ ss; RConnection conn; RSubConnection subconn; RSocket sock; TRequestStatus status; // Connect to ESOCK ss.Connect(); // Open an Connection conn.Open(ss, KAfInet); // Start the connection conn.Start(status); User::WaitForRequest(status); // Create a new sub-connection subconn.Open(ss, RSubConnection::ECreateNew, conn); // Set Properties of the sub-connection subconn.SetParameters(…); // Open a TCP socket on the sub-connection sock.Open(ss, KAfInet, KSockStream, KProtocolInetTcp, subconn); _LIT(KRasAddr,"10.159.24.13"); const TInt KEchoPort = 7; TInetAddr destAddr; destAddr.Input(KRasAddr); destAddr.SetPort(KEchoPort); // Request the Socket to connect to the destination over the sub-connection sock.Connect(destAddr, status);
Note: Error handling is not included to aid clarity.
