CAN_ERROR

The CAN_ERROR type is defined in can_error.h. It defines the error return values for the CAN driver routines. The CAN_ERROR type is defined as:

typedef enum {
  CAN_OK = 0,                  /* No error                            */
  CAN_NOT_IMPLEMENTED_ERROR,   /* Function has not been implemented   */
  CAN_MEM_POOL_INIT_ERROR,     /* Memory pool initialization error    */
  CAN_BAUDRATE_ERROR,          /* Baudrate was not set                */
  CAN_TX_BUSY_ERROR,           /* Transmitting hardware busy          */
  CAN_OBJECTS_FULL_ERROR,      /* No more rx or tx objects available  */
  CAN_ALLOC_MEM_ERROR,         /* Unable to allocate memory from pool */
  CAN_DEALLOC_MEM_ERROR,       /* Unable to deallocate memory         */
  CAN_TIMEOUT_ERROR,           /* Timeout expired                     */
  CAN_UNEXIST_CTRL_ERROR,      /* Controller does not exist           */
  CAN_UNEXIST_CH_ERROR,        /* Channel does not exist              */
} CAN_ERROR;

and is used as shown in the following example:

#include <can_error.h>
   ..
  CAN_ERROR retval;
   ..
  retval = CAN_send (2, &msg_buf, 0x0F00);
   ..
