IN:

Vgroup identifier returned by Vattach

Purpose

Detaches a currently-attached vgroup, terminating further access to that vgroup.

Return value

Returns SUCCEED (or 0) if successful and FAIL (or -1) otherwise.

Description

All space associated with the specified vgroup will be freed. Each attached vgroup should be detached by calling this routine before the file is closed. Vdetach also updates the vgroup information in the HDF file if any changes occur. The identifier vgroup_id should not be used after that vgroup is detached.
