^^^^^^^
This is not terribly likely to return
an IP address. On systems without a harware ID
the default hostid may be based on the IP address,
but these tend to also have sethostid(), which
may be used by the sysadmin to set any other value.
To bind to the primary address one must
char name[MAXHOSTNAMELEN];
struct hostent *hp;
gethostname(name,MAXHOSTNAMELEN);
if ( (hp=gethostbyname(name)) == NULL ) {
/* error */
...
}
bcopy(hp->h_addr,&loc_host_addr,sizeof(loc_host_addr));
