Sorry, I don't know exact answers at the moment and don't want to search the APIs, as you can do it yourself.
I only have one advice: if you know some function on Windows, stop looking for something similar in Linux. The systems have a lot in common (mostly because they always borrowed ideas) but still are very different. At first, approach Linux separately and learn it to certain extent; this way should be easier overall.

Solution 2

This is not so easy in Linux.

Please see: http://stackoverflow.com/questions/9178360/getting-disk-label-in-linux-in-c-c[^].

Pay attention for the advice so use C++ and Boost.Filesystem, referenced.
