Function
Retrieves the data transfer times when the "Event that the specified number of data are transferred" is used.
This settings is necessary when the transfer mode of the conversion data that is set by AioSetAoTransferMode function is User buffer mode.
This function needn't be executed if the transfer mode of the conversion data is Device buffer.
Format
Ret = AioGetAoEventTransferTimes ( Id , AoTransferTimes )
Parameters
Id [ C, C++ : short ] [ Python : ctypes.c_short ]
Specifies the Device ID retrieved from AioInit function.
AoTransferTimes [ C, C++ : long * ] [ Python : ctypes.POINTER(ctypes.c_long) ]
Specifies the address of the variable that stores the data transfer times when the event raises.
Return value
Ret [ C, C++ : long ] [ Python : ctypes.c_long ]
