Retrieves the sampling count (location) from
the device memory (software memory).
This function can only be used when the transfer mode of the conversion
data that is set by AioSetAiTransferMode is Device buffer mode.
It cannot be used when the transfer mode of the conversion data is User
buffer mode.
Ret = AioGetAiSamplingCount ( ID , AiSamplingCount )
Id
[ VB.NET : Short ] [ C, C++ : short ] [ C# : short ] [ Python : ctypes.c_short
]
Specifies the ID retrieved from AioInit function.
AiSamplingCount
[ VB.NET : Integer ] [ C, C++ : long * ] [ C# : out int ] [ Python : ctypes.POINTER(ctypes.c_long)
]
Specifies the address of the variable that stores the sampling count
Ret [ VB.NET : Integer ] [ C, C++ : long ] [ C# : int ] [ Python : ctypes.c_long ]

In all devices, AiSamplingCount = 0
Resets this value to 0 by calling AioResetAiMemory function.
Stores the sampling
count (location) that belong to the channels used by AioStartAi.
In the Ring memory format, return 0 to the sampling count at the gap of
memory.
This function can be executed if the device is working.
This function cannot be used on devices without the analog input function.
