Hi,
Can somebody provide me with a programming example on how to retrieve
state using rt_dev_ioctl .
The following (untested) code snippet should work:
struct ifreq ifr;
can_state_t *pstate;
...
pstate = (can_state_t *)&ifr.ifr_ifru;
ret = rt_dev_ioctl(fd, SIOCGCANSTATE, &ifr);
if (ret) {
perror("rt_dev_ioctl");
return;
}
printf("Current state = %d\n", *pstate);
RT-Socket-CAN allows a very flexible error handling. Please have a look
to
