Data Structures
struct	CO_CANinterfaceErrorhandler_t
	socketCAN interface error handling More...

Macros
#define	CO_CANerror_NOACK_MAX   16
	This is how many NO-ACKs need to be received in a row to assume that no other nodes are connected to a bus and therefore are assuming listen-only.
#define	CO_CANerror_LISTEN_ONLY   10
	This is how long we are going to block transmission if listen-only mode is active.

Enumerations
enum	CO_CANinterfaceState_t { CO_INTERFACE_ACTIVE , CO_INTERFACE_LISTEN_ONLY , CO_INTERFACE_BUS_OFF }
	driver interface state More...

Functions
void	log_printf (int priority, const char *format,...)
	Message logging function.
void	CO_CANerror_init (CO_CANinterfaceErrorhandler_t *CANerrorhandler, int fd, const char *ifname)
	Initialize CAN error handler.
void	CO_CANerror_disable (CO_CANinterfaceErrorhandler_t *CANerrorhandler)
	Reset CAN error handler.
void	CO_CANerror_rxMsg (CO_CANinterfaceErrorhandler_t *CANerrorhandler)
	Message received event.
CO_CANinterfaceState_t	CO_CANerror_txMsg (CO_CANinterfaceErrorhandler_t *CANerrorhandler)
	Check if interface is ready for message transmission.
CO_CANinterfaceState_t	CO_CANerror_rxMsgError (CO_CANinterfaceErrorhandler_t *CANerrorhandler, const struct can_frame *msg)
	Error message received event.
