The following (untested) code snippet should work:

     struct ifreq  ifr;
     can_state_t *pstate;
     ...
     pstate =3D (can_state_t *)&ifr.ifr_ifru;
     ret =3D rt_dev_ioctl(fd, SIOCGCANSTATE, &ifr);
     if (ret) {
	perror("rt_dev_ioctl");
	return;
     }
     printf("Current state =3D %d\n", *pstate);

RT-Socket-CAN allows a very flexible error handling. Please have a look=20
