Types and structures• dwStatus:[out] Current status of the CAN controller. The value is a combination of one ormore of the following constants:CAN_STATUS_TXPEND:The CAN controller is currently sending a message to the bus.CAN_STATUS_OVRRUN:A data overrun in the receive buffer of the CAN controller has taken place. This status canonly be reseted through a CAN controller reset ( see §4.3.1.7).CAN_STATUS_ERRLIM:An overrun of an error counter of the CAN controller has taken place.CAN_STATUS_BUSOFF:The CAN controller has changed to the “BUS-OFF” status.CAN_STATUS_ININIT:The CAN controller is in the stopped status.5.2.3 CANCHANSTATUSThe data type describes the current status of a CAN message channel. The structureis as follows:typedef struct{CANLINESTATUS sLineStatus;BOOL32fActivated;BOOL32fRxOverrun;UINT8bRxFifoLoad;UINT8bTxFifoLoad;} CANCHANSTATUS, *PCANCHANSTATUS;• sLineStatus:[out] Current status of the CAN controller. Further information is given in thedescription of the data structure CANLINESTATUS.• fActivated:[out] Indicates whether the message channel is currently active (TRUE) or inactive(FALSE).• fRxOverrun:[out] Indicates with the value TRUE whether an overrun of the receive buffer ofthe CAN controller has taken place. (see §5.2.2 CAN_STATUS_OVRRUN).• bRxFifoLoad:[out] Current level of the receive buffer in per cent.• bTxFifoLoad:• [out] Current level of the transmit buffer in per cent.94Copyright IXXAT Automation GmbH C-API Programming Manual, Version 1.5
