Hi All,

I know how to sniff packets using tcpdump.But i want to call tcpdump utility in a function.How to do that ? I do not want to cal system() function. Do you have any idea on how to do that ?

Thanks a ton in advance.

Thanks,
Pavan

what do you actually want to do with this call? Maybe you actually want to bypass tcpdump and use libpcap itself? That's certainly a lot more programatical from C.

Yes.You are right.Is there a way to call any exposed function which is being used by tcpdump utility to process all CLI inputs ?

If there is something like that, i can directly call function with my arguments.

Thanks,
Pavan

I'd suggest you look up the standard online docs for libpcap and go from there.
