TCP TraceRoute

I need to expand my code to be able to do a TCP trace route in code (Using syn packets with increasing TTL) in the same way that the linux command line utility does.

Does anyone here have any experience in doing this? I did find some code that was supposed to do it using a dll called rawtcpip.dll however it does not work and there is no source code for the dll itself. I would like to avoid using winpcap to do this and was hoping that there is a raw sockets example of doing this somewhere or that someone here had experience in this area.

thanks
