：
offset address, which can be found on the user manual.
*pResult
：
The fetched value.
Return value ： 0 ： Success ； -1: Failure.
WriteDevice()
long _stdcall WriteDevice( unsigned long Index, unsigned long nOffset, unsigned long
DataToWrite)
Notes
：
To perform 32-bit write IO operation on the board register. This function is a low-level
hardware function, which normally will not be used during normal programming. Refer
to "Chapter 5, Register Detail" for its offset addresses and corresponding functions if
you need to use this it.

AiConfig()
long _stdcall AiConfig( unsigned long Index, unsigned long StartMode, unsigned long
IrqMode, unsigned long ScanMode)
Notes
：
Configure the DAQ card register, that is write offset address 32.
Parameter
：
Index
：
card index, to select the card to manage.
StartMode
：
start mode, 0 for software startup, 1 for external trigger timing start
