Hello everybody,
I am trying to read the mac adders from my Network Interface Card, i noticed
this option is supported since rtnet-0.9.10. I tried the following:
ret = rt_dev_ioctl(Sock, SIOCGIFHWADDR, &readMAC);
if (ret < 0) {
rt_dev_close(Sock);
rtapi_print_msg(RTAPI_MSG_ERR, "Read MAC error %d\n", ret);
return -1;
}
else { rtapi_print_msg(RTAPI_MSG_ERR, "Read MAC OK\n"); }
It return error -19. Does any body know what is the meaning of this error
number?
I also tried the SIOCGIFINDEX, but it returns the same error.
I am using RTAI.Does anybody have an idea what could be the problem?
Best RegardsKlemen
