TCP_Server.cpp

This is an example for a very simple TCP server application.

Output when the TCP_Client is started:

TCP server sucessfully sent data to the client.

#include <TCPSocket.h>

#include <iostream>

static const char send_msg[] = "The quick brown fox jumps over the lazy dog";

int main()
{
    try {

    NET::TCPSocket server_socket;

    // listen locally on the given port
    server_socket.bind( "127.0.0.1", 47777);
    server_socket.listen();

    NET::TCPSocket::Handle handle = server_socket.timedAccept(5000);
    // nobody connected within 5s
    if(!handle) return 1;

    // create a new socket to communicate with the connected client
    // if we do nothing at this point, the connection will be discarded
    NET::TCPSocket session_socket(handle);
    session_socket.send( send_msg, sizeof(send_msg) );

    // client disconnected before he could receive anything
    if( session_socket.peerDisconnected()) return 1;

    std::cout << "TCP server sucessfully sent data to the client." << std::endl;

    // this is optional, we could simply do nothing here
    session_socket.disconnect();

    // if something fails, we get here
    } catch( const NET::SocketException& e)
    {
        std::cerr << e.what() << std::endl;
        return 1;
    }

    return 0;
