This doesn't sound correct to me, WritePrivateProfileString manages all the above, the only thing it won't do is delete a section if all the entries are removed, but I don't really see that as a big problem.

Files are created if they don't exist, if they do already exist then extra lines are added including section headings if they didn't previously exist. Writing with an empty value cause the entry to be deleted.
