An Iostream-Compatible Socket Wrapper

Listing 3: Simple client program that sends a message using the TCPSocketWrapper class

#include "Sockets.h"
#include <iostream>
#include <cstring>

using namespace std;

int main()
{
    if (socketsInit() == false)
    {
    cout << "cannot initialize sockets library"
        << endl;
    return 0;
    }

    try
    {
        const char *message = "Hello, Socket!";
        int msglen = strlen(message) + 1;

        TCPSocketWrapper sock;

        // connect to the same machine
        // and the IP port of the server process
        sock.connect("127.0.0.1", 12345);

        sock.write(message, msglen);
    }
    catch (const SocketRunTimeException &e)
    {
        cout << "socket exception: "
            << e.what() << endl;
    }

    socketsEnd();

    return 0;
}
