Vgroup Programming Model
The 'general' programming model for accessing Vgroups is as follows:
- Open a file and obtain a file identifier
- 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)
