zfs code - May 2007 - ZFS properties

Hi all!

I need to get some information about the zfs file system from my  
application, i.e reserved space, used space, space used by a specific  
snapshot etc.
Until now I have forked a process and used the CLI and a pipe to receive  
the output (zfs get -H -o value -p used,reservation tank/jabbathehut).

I am changing my application to use libzfs instead of the CLI. Does anyone  
know how to get this information when using libzfs? It is no problem with  
the standard operations such as create/destroy/rollback, but I can''t
seem
to figure out how to get the file system properties. I have browsed  
through some of the source code, but no lights started flashing :)

Thanks!

Lars-Erik

See zfs_prop_get() as well as zfs_get_user_props().  Of course, these
functions are subject to change without notice, but I assume you know
that already ;-)
