How do I read system information in C++?

Question

I\'m trying to get information like OS version, hard disk space, disk space available, and installed RAM on a Linux system in C++. I know I can use system() to run

If you don't want to use HAL as litb suggests, you can read things straight out of the /proc filesystem, provided it's there on your system. This isn't the most platform-independent way of doing things, and in many cases you'll need to do a little parsing to pick apart the files.

I think HAL abstracts a lot of these details for you, but just know that you can read it straight from /proc if using a library isn't an option.
