AioGetAoEventSamplingTimes

Function

Retrieves the number of generatings when "Event that the specified number of data are output" is used.

Format

Ret = AioGetAoEventSamplingTimes ( 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) ]
When the event factor is AOE_DATA_NUM, specifies the address of the variable that stores the number of generatings that raises event.

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.
13310	Pointer to AoSamplingTimes is NULL Specify the address of variable to parameter.
20001	This function can't be used by this device
20002	Can not use while by another device works To use this function, analog output operation must be stopped.
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, AoSamplingTimes = 500

Remarks

This function cannot be used on devices without the analog output function.
If the device is in operation, the function cannot be performed.

Example

Retrieves the number of generatings when "Event that the specified number of data are stored" is used.

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