Getting IP in a script

[Deepak Saxena]

No, wrong.  Looks like the ioctl takes a struct ifr, defined in 
<linux/include.h>.  Put the device name into the name field,
send the ioctl, and the addrs comes back in the ifru_addr field,
which will be of type sockaddr_in.

struct ifreq
{
#define IFHWADDRLEN     6
#define IFNAMSIZ        16
        union
        {
                char    ifrn_name[IFNAMSIZ];  /* if name, e.g. "en0" */
        } ifr_ifrn;

        union {
                struct  sockaddr ifru_addr;
                struct  sockaddr ifru_dstaddr;
                struct  sockaddr ifru_broadaddr;
                struct  sockaddr ifru_netmask;
                struct  sockaddr ifru_hwaddr;
                short   ifru_flags;
                int     ifru_ivalue;
                int     ifru_mtu;
                struct  ifmap ifru_map;
                char    ifru_slave[IFNAMSIZ];   /* Just fits the size */
                char    ifru_newname[IFNAMSIZ];
                char *  ifru_data;
        } ifr_ifru;
}
