As I was navigating through the source code for the ZFS file system I saw that
in zvol.c where the ioctls are defined, if a program sends a DKIOCGGEOM or
DKIOCDVTOV, an ENOTSUP (Error Not Supported) is returned.
You can view this here:

My question is, what is an appropriate method to obtain the zpool's volume size
from a C coded application?
I use zprop_get_list and zfs_prop_get form libzfs to read and parse zfs
properties. There may be a more direct way, but zprop_get_list appears
to be the generic solution.
