call

system("df > /tmp/df.out");

and parse the output file accordinfg to df command manual http://www.computerhope.com/unix/udf.htm

Maybe you want to use parameters for df command to limit the search or change formatting.

All the information you need is in the procfs file system.

Since you gave a B grade, I assume that something is still unclear. Do not hesitate to ask for clarification where needed in that case.

We expected something like system call to get that information. This is also good one, now using the same one.
Thanks.

The procfs file system is the standard interface to get this kind of information (that's what it was designed for anyway).
