    This is an example illustrating the use of the iosockstream object from the
    dlib C++ Library.

    This program simply connects to www.google.com at port 80 and requests the
    main Google web page.  It then prints what it gets back from Google to the
    screen.

#include <dlib/iosockstream.h>
#include <iostream>

using namespace std;
using namespace dlib;

int main()
{
    try
    {
        // Connect to Google's web server which listens on port 80.  If this
        // fails it will throw a dlib::socket_error exception.  
        iosockstream stream("www.google.com:80");

        // At this point, we can use stream the same way we would use any other
        // C++ iostream object.  So to test it out, let's make a HTTP GET request
        // for the main Google page.
        stream << "GET / HTTP/1.0\r\n\r\n";

        // Here we print each character we get back one at a time. 
        while (stream.peek() != EOF)
        {
            cout << (char)stream.get();
        }
    }
    catch (exception& e)
    {
        cout << e.what() << endl;
    }
