Moves the iterator to the next topology.
(tpm_iternext iter_id)
Returns T or nil if another topology is not present.
| iter_id | Iterator ID (real) |
The first time this function is called after tpm_iterstart, it sets the iterator on the first topology definition.
For an example that shows how you can use Topology Iterating functions to find all the topologies the system knows about, see tpm_iterstart.
