kernel 2.2 socket programming

Hello, maybe I'm wrong here. I have a queston on socket programming, I have read in the raw 7 manual page, in Linux 2.2 I can set all IP header fields using IP socket options, dont need a raw socket. Does anybody now what options I must use, maybe somebody have or knows where I can get an example. Best Regards H. Voggenreiter Network Admin / Hostmaster Bezirk Oberbayern Germany
