Function Documentation

dict_lookup()

int dict_lookup	(	struct ip_user_dict *	first_entry,
		char *	username,
		char *	address
	)

This function looks for a matching ip/mask in the dict file loaded in memory. It returns 1 if it finds a match or 0 if no match is found

load_dict()

struct ip_user_dict * load_dict

(

FILE *

FH

)

This function parses the dictionary file and loads it in memory. All IP addresses are processed with a bitwise AND with their netmasks before they are stored. If there?s no netmask (no /) in the in the lhs , a mask 255.255.255.255 is assumed. It returns a pointer to the first entry of the linked list
