How to get path of all the Builtin functions in LabVIEW?

[SivaShankar]

I need to create my custom functions palette and need to change the items programmatically using "Write Palette.vi". It requires the item path as the input to get populated in the palette. I can give the path of the VI if it is available in disk but in the case of builtin functions of Labview I need to give the path as  BUILT_IN_FUNC_**_**_**_*** . How to get the paths of all the builtin functions? I can get it for some of functions by reading the .mnu file using Read Palette.vi but I could not get the names of the each function so it is difficult to map the functions with the path.

Many LabVIEW vi's are located in vi.lib, which is usually found in your install directory, C:\Program Files\National Instruments\LabVIEW 2013.

Should that fail, you can just do a search for *.vi, which will show up all the VI's on your computer, including the ones LabVIEW has in its install directory.

The LabVIEW functions are part of the runtime engine and are not VIs.

How to bring LabVIEW functions like Add, Divide and etc. to my palette using "Write to Palette.vi" ? This vi requires item path as an input, How to get these item path? Manually we can bring the LabVIEW functions to the palette using Edit palette set. But I want to do it programmatically.
