Ret = AioGetAiRepeatCount ( ID , AiRepeatCount )

Parameters

Id [ C, C++ : short ] [ Python : ctypes.c_short ]
Specifies the Device ID retrieved from AioInit function.

AiRepeatCount [ C, C++ : long * ] [ Python : ctypes.POINTER(ctypes.c_long) ]
Specifies the address of the variable that stores the repeat count.

This function can be executed if the device is working.

Example

Retrieves the current repeat count.

C, C++

long Ret;
long AiRepeatCount;
Ret = AioGetAiRepeatCount ( Id , &AiRepeatCount );
 

Python

Ret = ctypes.c_long()
AiRepeatCount = ctypes.c_long()
Ret.value = caio.AioGetAiRepeatCount ( Id , ctypes.byref(AiRepeatCount) )
