how about line 182 of snort.c?

geschke$ grep -n "int main" snort-2.4.3/src/snort.c
182:int main(int argc, char* argv[]) 

You should also take a look at line 101 of snort-2.4.3/src/detect.c. Here
is the function Preprocess declared which loops over all defined preprocessors
and finally calls Detect() to check against the rules.

Best regards
