Determine port number from an IceInternal::ProxyHandle<T> in C++

How can this be done?
If I can't, can I print a IceInternal::ProxyHandle<T> to std::cout like I can in ruby?

    The proxy API let you access the endpoint and connection info, the connection is only available if the proxy is associated with a connection.

    Check the proxy API in the docs https://doc.zeroc.com/display/Ice/Proxy+Methods

    Here is some sample code 
    Ice::ObjectPrx proxy = communicator()->propertyToProxy("Hello.Proxy");

//
// Get the info of associated endpoints
//
Ice::EndpointSeq endpoints = proxy->ice_getEndpoints();
for(Ice::EndpointSeq::const_iterator i = endpoints.begin(); i != endpoints.end(); ++i)
{
    Ice::IPEndpointInfoPtr info = Ice::IPEndpointInfoPtr::dynamicCast((*i)->getInfo());
    if(info)
    {
        cerr << "type: " << info->type() << " host: " 
             << info->host << " port: " << info->port << endl;
    }
}

//
// checkedCast to force a new connection
//
HelloPrx twoway = HelloPrx::checkedCast(proxy);

//
// Now access the connection info
//
Ice::ConnectionPtr conn = twoway->ice_getCachedConnection();
if(conn)
{
    Ice::IPConnectionInfoPtr info = Ice::IPConnectionInfoPtr::dynamicCast(conn->getInfo());
    if(info)
    {
        cerr << "localAddress: " << info->localAddress 
             << " localPort: " << info->localPort << "\n"
             << "remoteAddress: " << info->remoteAddress 
             << " remotePort: " << info->remotePort << endl;
    }
}

    Thanks Jose,

    I tried to use this bit: 
    //
// Get the info of associated endpoints
//
Ice::EndpointSeq endpoints = proxy->ice_getEndpoints();
for(Ice::EndpointSeq::const_iterator i = endpoints.begin(); i != endpoints.end(); ++i)
{
    Ice::IPEndpointInfoPtr info = Ice::IPEndpointInfoPtr::dynamicCast((*i)->getInfo());
    if(info)
    {
        cerr << "type: " << info->type() << " host: " 
             << info->host << " port: " << info->port << endl;
    }
}

    but (I guess because we're using Ice 3.3.0) this doesn't compile. I changed it as follows but this causes a core:
    Ice::EndpointSeq endpoints = proxy->ice_getEndpoints();
for(Ice::EndpointSeq::const_iterator i = endpoints.begin(); i != endpoints.end(); ++i)
{
  cout << (*i)->toString() << endl;
}

    It is difficult to know without seeing the crash stack trace, can you post one?

    You should also consider updating to the latest release
