"Assuming you're on Windows.." does not imply that it is cross platform.
I was saying that because Acharis asked for a cross-platform solution in this post... these things can be easy to miss, and it seems gratuitous to lock yourself to the Windows API when (a) there are plenty of drop-in libraries that are already cross-platform and (b) you can write your own basic parser anyway in under ten minutes if you really wanted to. Also, ini files aren't Windows specific, they just happen to be found more on Windows, you can certainly store your settings in any format you like on any system you like (let's face it, key-value stores aren't exactly an uncommon format).
Having a library that abstracts the actual configuration data from its storage sounds like a useful thing to have though.
