47  * VG handle, vg_t. Performing an operation on a PV or LV object first
48  * requires obtaining a VG handle. Once the vg_t has been obtained, it can
49  * be used to enumerate the pv_t's and lv_t's within that vg_t. Attributes
53  * Any attempt to change a property of a pv_t, vg_t, or lv_t without
54  * obtaining write permission on the vg_t will fail with EPERM.
