AioQueryDeviceName

Function

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

Format

Ret = AioQueryDeviceName(Index, DeviceName, Device)

Parameters

Index [ C, 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 [ C, C++ : char * ] [ Python : ctypes.c_char_p ]
Returns the device name. (For example: "AIO000")

Device [ C, C++ : char * ] [ Python : ctypes.c_char_p ]
Returns the board name. (For example: "AIO-163202F-PE")

Return values

Ret [ C, C++ : long ] [ Python : ctypes.c_long ]

Return values	Content
0	Normality completion
10006	Device not found Make sure that the device is registered in Configuration Tool (config)
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.

Example

Retrieves the information of the device by Index=0.

C, C++	long Ret; char DeviceName[256]; char Device[256]; Ret = AioQueryDeviceName ( 0 , DeviceName , 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 )
