Hopen (hopen)

Initialize the Vdata/Vgroup interface
Vstart (vfstart)

Attach to an existing Vgroup or create a new Vgroup
Vattach (vfatch)

Perform Miscellaneous Operations (reading, writing, etc.)

Terminate access to a Vgroup
Vdetach (vfdtch)

Terminate access to the Vdata/Vgroup interface
Vend (vfend)

Close the file
Hclose (hclose)
