A. Opening a socket for management API
int s;
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);
}
