ADLINK PCI-7841/cPCI-7841 - Manual (Page 41)

Function Reference 33
#include “pci7841.h
int handle = CanOpenDriver(0, 0);//open the port
0 of card 0
….
BYTE error_count = CanGetRxErrorCount();
CanCloseDriver(handle);
CanGetTxErrorCount()
Purpose Get the current value of the transmit error
counter

BYTE CanGetTxErrorCount(int handle)
Parameters handle : handle retrieve from CanOpen-
Driver()
Return Value value
Remarks This function reflects the current of the
transmit error counter. After hardware reset
happened, the value would set to 127. A
bus-off event occurs when the value
reaches 255. You can call the CanSetTxEr-
rorCount() to set the value from 0 to 254 to
clear the bus-off event.
