Would you mind clarifying this question? I don't think I know the answer, but if I did I would probably need to know the following:

Are you writing a programme in C, and if so what is the purpose of that programme?

Do you want to block a specific website/IP address? That is actually quite easy.

What are you trying to achieve in general?

That might help you get a decent answer ... I think ...
