AioSetAoMemoryType

Function

Sets the memory type for storing data.

Format

Ret = AioSetAoMemoryType ( Id , AoMemoryType )

Parameters

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

AoMemoryType [ C, C++ : short ] [ Python : ctypes.c_short ]
Specifies the memory type for storing data from the following range.

Device buffer

0	FIFO
1	RING

User buffer

0	Not repeat output
1	Repeat output

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.
13140	The value of AoMemoryType is outside the designated range of the function Set 0(FIFO) or 1(RING) to AiMemoryType.
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.
23140	The value of AoMemoryType is outside the designated range of the device being used

Initial value

In all devices, it is FIFO when the device buffer is used, or it is "Not repeat output" when the user buffer is used.

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

Sets the memory for the output data in FIFO.

C, C++	long Ret; Ret = AioSetAoMemoryType ( Id , 0 );
Python	Ret = ctypes.c_long() Ret.value = caio.AioSetAoMemoryType ( Id , 0 )
