Functions

• char * get_proto_name (unsigned int proto)

  get protocol name (asciiz).
  

• int ip_addr_match_net (ip_addr_t *iaddr, ip_addr_t *naddr, int mask)

  match ip address with net address and bitmask

  • return 0 on match, -1 otherwise

  
  

• int mk_net (struct net *n, struct ip_addr *ip, struct ip_addr *mask)

  fills a net structure from an ip and a mask.
  

• int mk_net_bitlen (struct net *n, struct ip_addr *ip, unsigned int bitlen)
