| struct sockaddr * | src, | |||
| char * | ifname | |||
| ) | [static] |
Extract the network address part from a "struct sockaddr".
The address family is given explicitly instead of using src->sa_family, because the latter does not work for copying a network mask obtained by SIOCGIFNETMASK (it does not have a valid address family).
