doc\can\test - imx-test - i.MX Driver Test Application Software

GitHub - linux-can/can-utils: Linux-CAN / SocketCAN user space applications

In my code if I try to bind the can socket getting an error, please do let me know what could be the reason,

pleas find the code below,

struct sockaddr_can addr;
struct can_frame frame;
struct ifreq ifr;

const char *ifname = "vcan0";

if((s = socket(PF_CAN, SOCK_RAW, CAN_RAW)) < 0) {
perror("Error while opening socket");
return -1;
}

strcpy(ifr.ifr_name, ifname);
ioctl(s, SIOCGIFINDEX, &ifr);

addr.can_family = AF_CAN;
addr.can_ifindex = ifr.ifr_ifindex;

if(bind(s, (struct sockaddr *)&addr, sizeof(addr)) < 0) {
perror("Error in socket bind");
return -2;
}
