Read /etc/mnttab to see what devices are mounted, and use the ustat
system call to check the status of each.  Or, if you are wondering how
big you can make a certain file, you can also stat() the file (or the
directory in which you intend to create it) to see what device it is
on, and ustat() that.

See mnttab(4), stat(2), ustat(2).
