Lock file

I'm not aware of a way to lock file access using native CVI functions.

You can obtain this by using Windows API functions like CreateFile with the appropriate attributes or LockFile on an unlocked, opened file; you will need of course to continue using Win32 APIs to read/write to the file, as the system handle is not compatible with CVI file functions.
