Hi,

I am reading ip_tables.h. There is a structure called  ipt_target. In it there is pointer to a function which is below.
unsigned int (*target)(struct sk_buff **pskb, .......)

I can not find the original function that this function pointer(*target) points. When I search for target, I see that it is defined in 6 files. Which one is used and when? How can I understand it? (this is same for match and checkentry functions)

6 files in which target is defined;

thanks,
