Retrieves the timing of external clock input.
Ret = AioGetAoClockEdge ( Id , AoClockEdge )
Id
[ VB.NET : Short ] [ C, C++ : short ] [ C# : short ] [ Python : ctypes.c_short
]
Specifies the ID retrieved from AioInit function.
AoClockEdge
[ VB.NET : Short ] [ C, C++ : short * ] [ C# : out short ] [ Python :
ctypes.POINTER(ctypes.c_short) ]
Specifies the address of the variable that stores the timing of external
input.

External input falling edge is used for all devices. *
* in case of using ADA16-8/2(LPCI)L and DA16-16(LPCI)L
In these devices, the default value has both parameters (rising or falling),
it depends on manufacturer's serial version.
This function cannot be used on devices without
the analog output function.
If the device is in operation, the function cannot be performed.
