Function
Retrieves the number of generating when "Event that the specified number of data are output" is used.
Format
Ret = AioGetAoEventSamplingTimes ( Id , AoSamplingTimes )
Parameters
Id
[ C, C++ : short ] [ Python : ctypes.c_short ]
Specifies the Device ID retrieved from AioInit function.
AoSamplingTimes
[ C, C++ : long * ] [ Python : ctypes.POINTER(ctypes.c_long) ]
When the event factor is AOE_DATA_NUM, specifies the address of the variable
that stores the number of generating that raises event.
Return value
Ret [ C, C++ : long ] [ Python : ctypes.c_long ]
