Creating a new sub-connection - Socket connected over the sub-connection

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);
