How can I embed raw packets into my network

Question

When testing some functions of receiving network device drivers, I need to send special packets to the wire. I know that I need to open a raw socket and push out bytes. Is there any known example (C, perl, any) of code already available for playback at this level?

(added later) I would prefer non-platform answers, they will be most useful for everyone.

Answer 1

I found that there is a good example here on Security-Freak , which required only a small modification for flexibility. I hope there are more answers in other languages.
