I've never used c++ but I did a test in C# which was successful.  This is not
a working code example but may give you an idea:



using System;
using System.Runtime.InteropServices;

//Callback delegate
public delegate int CallbackInt();
public delegate void CallbackVoid();

//Set up callbacks to HTTrack's non-COM DLL
const string sHttrackLib = "libhttrack.dll";

[DllImport(sHttrackLib, CallingConvention=CallingConvention.Cdecl)]
    public static extern int hts_uninit();

htsCallBack = new CallbackVoid(httrack_wrapper_uninit);
returnVal = HttrackLib.htswrap_add( "free", htsCallBack );
OutputMessage( "Wrapper add: \"free\": " + returnVal.ToString() + "\n" );

CallbackInt htsCallBackInt = new CallbackInt(httrack_wrapper_end);
returnVal = HttrackLib.htswrap_add( "end", htsCallBackInt );
OutputMessage( "Wrapper add: \"end\": " + returnVal.ToString() + "\n" );

//The callback functions
//Two used when HTTrack finishes
public int httrack_wrapper_end()
{
    OutputMessage( "End of mirror.\n" );
    return 1;
}

public void httrack_wrapper_uninit()
{
    OutputMessage( "wrapper_uninit: Engine exited.\n" );
}
