AioGetAoMemoryType

Function

Retrieves the memory type for storing data.

Format

Ret = AioGetAoMemoryType ( Id , AoMemoryType )

Parameters

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

AoMemoryType [ VB.NET : Short ] [ C, C++ : short * ] [ C# : out short ] [ Python : ctypes.POINTER(ctypes.c_short) ]
Specifies the address of the variable that stores the memory type for storing data.
The stored value meanings depends on the transfer mode that is decided by AioSetAoTransferMode function.

Device buffer

0	FIFO
1	RING

User buffer

0	Not repeat output
1	Repeat output

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.

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, FIFO

Remarks

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