Retrieves the number of overwrite if the
user buffer is used in "Overwrite the memory".
This function can only be used when the transfer mode of the conversion
data that is set by AioSetAiTransferMode is User buffer mode.
It cannot be used when the transfer mode of the conversion data is Device
buffer mode.
Ret = AioGetAiTransferLap ( ID , Lap )
Id
[ VB.NET : Short ] [ C, C++ : short ] [ C# : short ] [ Python : ctypes.c_short
]
Specifies the ID retrieved from AioInit function.
Lap
[ VB.NET : Integer ] [ C, C++ : long * ] [ C# : out int ] [ Python : ctypes.POINTER(ctypes.c_long)
]
Specifies the address of the variable that stores the number of lap.
Ret [ VB.NET : Integer ] [ C, C++ : long ] [ C# : int ] [ Python : ctypes.c_long ]

In all devices, Lap = 0
Lap is automatically reset to 0 when the conversion is started by AioStartAi.
This function can be executed if the device
is working.
This function cannot be used on devices without the analog input function.
