AioQueryDeviceName

Function

Retrieves the list of available devices. This function supports multi-process.

Format

Ret = AioQueryDeviceName(Index, DeviceName, Device)

Parameters

Index [ VB.NET : Short ] [ C, C++ : short ] [ C# : short ] [ Python : ctypes.c_short ]
This parameter should be zero for the first call and then be incremented by 1 for subsequent calls.

DeviceName [ VB.NET : String ] [ C, C++ : char * ] [ C# : out StringBuilder ] [ Python : ctypes.c_char_p ]
Returns the device name. (For example: "AIO000")

Device [ VB.NET : String ] [ C, C++ : char * ] [ C# : out StringBuilder ] [ Python : ctypes.c_char_p ]
Returns the board name. (For example: "AD12-16U(PCI)EV")

Return values

Ret [ VB.NET : Integer ] [ C, C++ : long ] [ C# : int ] [ Python : ctypes.c_long ]

Return values	Content
0	Normality completion
10006	Device not found Make sure that the device is registered in device manager
10007	Pointer to DeviceName is NULL Specify the address of variable to parameter.
10008	Pointer to Device is NULL Specify the address of variable to parameter.

Remarks

This function can be used when you are creating a general-purpose application about the selected device to be used.
Index is incremented by 1 from 0 in order for subsequent calls until the function returns error.

Please be sure to connect the device before launching your application.
If the device is not connected, the device list may not be retrieved correctly.

Example

Retrieves the information of the device by Index=0.

VB.NET	Dim Ret As Integer Dim DeviceName As New StringBuilder("", 256) Dim Device As New StringBuilder("", 256) Ret = AioQueryDeviceName ( 0 , DeviceName , Device )
C, C++	long Ret; char DeviceName[256]; char Device[256]; Ret = AioQueryDeviceName ( 0 , DeviceName , Device );
C#	int Ret; string DeviceName; string Device; Ret = aio.QueryDeviceName ( 0 , out DeviceName , out Device );
Python	Ret = ctypes.c_long() DeviceName = ctypes.create_string_buffer(256) Device = ctypes.create_string_buffer(256) Ret.value = caio.AioQueryDeviceName ( 0 , DeviceName , Device )
