Is there a C++ cross platform key/value API or library for C++?

Question

We want to persist some user settings int he GUI part of our code. I used to do Win32 programming exclusively and the typical way this was done was with registry settings.

I assume that this should be done with configuration files, but was wondering if there was a library or cross platform wrapper that made key/value pair persistence very easy.

Qt's QSettings class handles this:
