AioGetAoRepeatCount

Function

Retrieves the current repeat count.

Format

Ret = AioGetAoRepeatCount ( Id , AoRepeatCount )

Parameters

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

AoRepeatCount [ C, C++ : long * ] [ Python : ctypes.POINTER(ctypes.c_long) ]
Specifies the address of the variable that stores the repeat count. The value is always 0 if the number of repeats is set to infinity.

Return value

Ret [ C, C++ : long ] [ Python : ctypes.c_long ]

Return values	Content
0	Normality completion
7	Execute AioResetDevice function because the device has recovered from standby mode
10001	Invalid Id was specified Use the Id retrieved from AioInit to specify the Id in this function.
10002	AIO driver can't be called At first, perform AioInit function.
13420	Pointer to AoRepeatCount is NULL Specify the address of variable to parameter.
20001	This function can't be used by this device
20003	Can not use because another process is using the device When another process is using the device, all functions except for those that support multi-process can not be performed.

Initial value

In all devices, AoRepeatCount = 0

Remarks

Resets this value to 0 by calling AioResetAoMemory function.

This function cannot be used on devices without the analog output function.
This function can be executed even if the device is in operation.

Example

Retrieves the current repeat count.

C, C++	long Ret; long AoRepeatCount; Ret = AioGetAoRepeatCount ( Id , &AoRepeatCount );
Python	Ret = ctypes.c_long() AoRepeatCount = ctypes.c_long() Ret.value = caio.AioGetAoRepeatCount ( Id , ctypes.byref(AoRepeatCount) )
