Is there an operating system API wrapper library for c++?

Question

Does sombebody know a C++ library for accessing different operating system APIs?

I'm thinking about a wrapper to access OS specific functions. Something like:

osAPI.MessageBox(); // calls MessageBox() in Win32, equivalent in Mac OS Linux etc...

Since I think it's hard to realize this for different OSes for now it would be also ok to have a nice C++ wrapper class for WinAPI.

I think you're looking for Trolltech's Qt C++ framework.

It's a cross platform C++ library for GUI and just about everything else cross platform.

And as of the latest version it is free to use for commercial use.
