7.3.2.6 EthCanGetStatus
Syntax:
DWORD STDCALL EthCanGetStatus(
tEthCanHandle EthCanHandle_p,
tStatus* pStatus_p);
Usability:
HW_INIT
Description:
The function returns the error status of the CAN-driver as well as the
connection status of the CAN-Ethernet Gateway. If a CAN-error
occurs on the CAN-Ethernet Gateway (e.g. send or receive buffer
overflow), then this status will be returned via Ethernet and can be
called up with the help of this function. In addition to the CAN-status
the current connection status of the Ethernet connection between the
PC and the CAN-Ethernet Gateway is also returned. This function
should be called in specific time intervals in order to be able to react to
potential CAN-errors.
Parameter:
EthCanHandle_p: Instance Handle of the CAN-Ethernet Gateway
pStatus_p: Address to a status structure. This address must not
be NULL!
This status structure is defined as follows:
typedef struct
{
WORD m_wCanStatus; // current CAN state
WORD m_wConnectionStatus; // current connection state
} tStatus;
