Driver Initialization & Deinitalization
extern "C" __declspec(dllexport) int __stdcall InstallDriver(void);
Input : None
Output : Return 1 if device driver loads successfully; otherwise return 0.
Note: This function should be invoked before Watchdog and Digital I/O
routines.
extern "C" __declspec(dllexport) int __stdcall RemoveDriver(void);
Input : None
Output : Always return 1.
Note: This function should be invoked before the program closes and it will
release the device driver and memory for ib_wdt.dll . If the program is closed
without calling this routine, resource leak may occur.
