AioGetAoSamplingTimes

Function

The remaining output data amount is acquired by generating number.

Format

Ret = AioGetAoSamplingTimes ( Id , AoSamplingTimes )

Parameters

Id [ VB.NET : Short ] [ C, C++ : short ] [ C# : short ] [ Python : ctypes.c_short ]
Specifies the ID retrieved from AioInit function.

AoSamplingTimes [ VB.NET : Integer ] [ C, C++ : long * ] [ C# : out int ] [ Python : ctypes.POINTER(ctypes.c_long) ]
Specifies the address of the variable that stores the number of generatings.

Return value

Ret [ VB.NET : Integer ] [ C, C++ : long ] [ C# : int ] [ 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.
13230	Failed in the allocation of the memory 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, 0

Remarks

The remaining output data amount is acquired by generating number.

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

Please use the AioGetAoSamplingCount function when you need the numbers of generated on device buffer.

For example, you specify 2000 data for device buffer and your device has already generated 500 data out of 2000 data.
You may have the following number with 2nd argument of each functions at that time.

AioGetAoSamplingCounts : AoSamplingCount = 500
AioGetAoSamplingTimes : AoSamplingTimes = 1500

Example

Get the remaining output data amount.

VB.NET	Dim Ret As Integer Dim AoSamplingTimes As Integer Ret = AioGetAoSamplingTimes ( Id , AoSamplingTimes )
C, C++	long Ret; long AoSamplingTimes; Ret = AioGetAoSamplingTimes ( Id , &AoSamplingTimes );
C#	int Ret; int AoSamplingTimes; Ret = aio.GetAoSamplingTimes ( Id , out AoSamplingTimes );
Python	Ret = ctypes.c_long() AoSamplingTimes = ctypes.c_long() Ret.value = caio.AioGetAoSamplingTimes ( Id , ctypes.byref(AoSamplingTimes) )
