[Qt-interest] Alternative for bind() in TCP sockets

[Anisha Kaul]

Thanks for replying, Saryesh,


// This is in the constructor---------------------------------
tcpServer = new QTcpServer();
if (!tcpServer->listen())
{
   close(0);
}
bool h = connect (tcpServer, SIGNAL(newConnection()), this, SLOT(myNewConnection()));
cout << "\nh: \n" << h; // prints 1

// The SLOT----------------------------------------------------
void QTcpSocketUtility :: myNewConnection ()
{
   objTcpSocket = tcpServer->nextPendingConnection ();
   bool h = connect (objTcpSocket, SIGNAL(newConnection()), objTcpSocket, SLOT(myNewConnection()));
   cout << "\nh: \n" << h;   
}

// Create socket function ------------------------------------
if (objTcpSocket == NULL)
{
   objTcpSocket = new QTcpSocket();
   cout << objTcpSocket->isOpen (); // prints 0

   objTcpSocket->setSocketOption (QAbstractSocket :: KeepAliveOption, QVariant (1));
   objTcpSocket->setSocketOption (QAbstractSocket :: LowDelayOption, QVariant (1));
}

// Receive Message function-------------------------------------
   cout << objTcpSocket->isOpen (); // prints 0
   returnValReadDatagram = objTcpSocket->read (receivedData, 0);
// returns -1
