Errors

The RL-CAN library routines return one of the following error constants to indicate status.

CAN_OK
Indicates the function completed successfully without error.
CAN_NOT_IMPLEMENTED_ERROR
Indicates the function is not implemented.
CAN_MEM_POOL_INIT_ERROR
Indicates that the memory pool used for software message buffers did not initialize successfully.
CAN_BAUDRATE_ERROR
Indicates that the communication speed was incorrectly initialized.
CAN_TX_BUSY_ERROR
Indicates that the transmit hardware is busy.
CAN_OBJECTS_FULL_ERROR
Indicates that no more transmit or receive objects may be defined.
CAN_ALLOC_MEM_ERROR
Indicates there is no available memory in the CAN memory pool.
CAN_DEALLOC_MEM_ERROR
Indicates that the memory used by the transmitted or received message was not correctly deallocated.
CAN_TIMEOUT_ERROR
Indicates that the timeout expired before a message was transmitted.
CAN_UNEXIST_CTRL_ERROR
Indicates that the requested CAN controller does not exist.
CAN_UNEXIST_CH_ERROR

If the function completes successfully and without error, CAN_OK is returned.
