retrieve OS folder path

[labmaster]

I need to know the installed OS folder path.

To my knowledge, I have to use some API function using call library.

Currently, Labwindows and any other NI product(toolkits) are available from NI full development package.

Is there some useful information(book or source code) on window API programming within any other NI products?

Thank you in advance.

The function you want is included in lvwutil.zip. You can search the developer zone for it's location.

The most comprehensive information on the windows api is on MSDN.
