// deactivate callback

nRC = CANSetCallbackEx( hHandle, MyCallbackEx );

getch(); // wait for keyboard input

// deactivate callback

nRC = CANSetCallbackEx( hHandle, 0 );

CANCloseDevice(hHandle);

}

return 0;

}

Remarks

The two different callback functions have to be used depending on the active setting of the global timestamp

option (CANSetGlobals). Only one of the callbacks can be activated at the same time.
