A. Opening a socket for management API

int

s = socket (PF_INET, SOCK_STREAM, 0);

B. Create request block for driver ioctl

  struct ifreq ifr;
  int subCmd;
  NpkUserCtl myIoc;

char myDataBuf[MAX_LINES * MAX_LINE_LEN];

/* set interface name */

strcpy (ifr.ifr_name, “eth1”);

/* set ioctl sub-type */

subCmd = DM_IOCTL_GET_STATS;

/* set command argument */
myIoc.arg1 = 0;

myIoc.dataItm = (u_int) myDataBuf;
ifr.ifr_data = (char *) &myIoc;

C. Issue ioctl command

/* issue ioctl to network driver */

err = ioctl (s, SIOCDEVPRIVATE + subCmd, &ifr);

D. Check and print results

if (err < 0)
{
/* perror (errno); */
usage ();
exit (1);
}
if (subCmd == DM_IOCTL_GET_TRC)
{
print_trace();
}
else
{
if ((subCmd != DM_IOCTL_SET_LOOP_MODE) &&
(subCmd != DM_IOCTL_PROG_EEPROM))
printf ("\n%s\n", myDataBuf);
}
