What is the Equivalent of Windows WMI for MacOS C++ Development?

I have a C++ application that gets detailed system information (processor type, available disk space, other hardware profile info) on Windows using WMI. I want to perform the same type of operations on OSX 10.5+. What is the equivalent API or interface开发者_如何学编程 for MacOS?

Links to API documentation or tutorials are very welcome.

You can query most of that information through the system_profiler executable. Apple's example for querying such informations involves a popen call to it, so I guess it's the way to go.
