Gets a topology type.
(tpm_itertype iter_id)
Returns a topology type code (int) or nil.
| iter_id | Iterator ID (real) |
The function gets the type of the topology that the iterator is pointing to. The topology type codes are 1 = node, 2 = network, 3 = polygon.
For an example that shows how you can use Topology Iterating functions to find all the topologies the system knows about, see tpm_iterstart.
