shared: split out in_addr related calls from socket-util.[ch] into its private in-addr-util.[ch] These are enough calls for a new file, and they are sufficiently different from the sockaddr-related calls, hence let's split this out. 2014-07-10 21:15:26 +02:00			`#include "in-addr-util.h"`

change type for address family to "int" Let's settle on a single type for all address family values, even if UNIX is very inconsitent on the precise type otherwise. Given that socket() is the primary entrypoint for the sockets API, and that uses "int", and "int" is relatively simple and generic, we settle on "int" for this. 2014-07-18 16:09:30 +02:00			`int family, ifindex;`

nss-myhostname: always resolve the host name "gateway" to the local default gateway This is useful inside of containers or local networks to intrdouce a stable name of the default gateway host (in case of containers usually the host, in case of LANs usually local router). 2014-12-03 21:42:58 +01:00			`uint32_t metric;`
