Download the source of the df program and study it.

If you are too lazy to do that (I am not saying it as an insult
but as finding an even easier way), then just run "strace df"
and see what system calls it execute. Or you can even run "ltrace df"
to see the library calls as well.

Hint. you need the statfs family of calls.

man statfs

You can either use fstatfs()/statfs(), or you can
run df with popen().

See the man page for statfs and/or vstatfs
