This sounds like a homework assignment.  Is this an assignment from a University?

Hey all ,
I'm  trying to program a small sniffer that will be using the structure of snort rules.
I want it to be very small so I need rally compact code(I will use C probably ).
So i wanted to know two things
.
A. is there a place the specific which of the snort rules are the most usefull, meaning what are the most pupullar 
"packets" that will be detect for the avrege web user? for the begining somthing about 20 rules will be enouge
 .
B. I need to parse the rules into a data structure .I search in forums but i  havn't found what is the actual structure 
that snort use and how the packet is being parse so it "feets" the strcuture of the rule....can somone recommend on 
data structure ? about parser?

Best regards,
Any help will be greatly appreciated
