Filesystem access in platform agnostic fashion?

Hi,

I’m new with cocos2d-x, so I’m probably missing many things.

That said, I wonder why http://www.cocos2d-x.org/reference/native-cpp/dd/de9/classcocos2d_1_1_c_c_application.html documents for instance CCApplication::getResourceRootPath(), but that member function appears to be missing at least on iOS?

Let’s say I have a directory tree that I’d like to incorporate into my package, rooted at some platform specific application directory.
Is there a recommended practice guide somewhere, or is this something that falls outside of cocos2d-x domain?

Thanks,

Harri
