SYNTAX

       #include "socket_if.h"

       int socket_local(int s,char ip[16],
                       uint16 *port,uint32 *scope_id);

       int socket_remote(int s,char ip[16],
                       uint16 *port,uint32 *scope_id);

DESCRIPTION

       socket_local returns the local IPv6 or IPv4-mapped IPv6 address as ip,
       port as port and perhaps the scope_id as scope_id for the UDP or TCP
       socket.

       socket_remote returns the remote IPv6 or IPv4-mapped IPv6 address as
       ip, port as port and perhaps the scope_id as scope_id for the UDP or
       TCP socket.

RETURN CODES

       If something goes wrong, socket_local and socket_remote return -1,
       setting errno appropriately.

EXAMPLE

       #include <socket_if.h>
         int s;
         char ip[16];
         uint16 port;

         if (socket_remote(s,ip,&port,0) == -1)
           strerr_die2sys(111,FATAL,"unable to get remote address: ");
