int can_frame_is_error | ( | const struct can_frame * | frame, |
enum can_state * | pstate, | ||
enum can_error * | perror | ||
) |
Checks if a SocketCAN CAN frame is an error frame and parses the bus state and error flags if it is.
frame | a pointer to a SocketCAN CAN frame. |
pstate | the address at which to store the updated CAN node state (can be NULL). The value is only updated if the error frame indicates a state change. |
perror | the address at which to store the updated CAN bus errors (can be NULL). Any new error flags indicated by by the error frame are set in *perror, but existing flags are not cleared. |
