Lists information about a tracing model element.
(tpm_traceelemget trace_id elem_id)
Returns an information list or nil.
| trace_id | Tracing model ID (real) returned by tpm_tracealloc |
| elem_id | Trace element ID (real) |
The list format depends on the element type. For each a-list, the first component is an integer code for the information type, and the second is the information.
| (-1 . elem_code) | Element type code (integer). With node lists, always 1, meaning node element. |
| (40 . resistance) | Node resistance (real). |
| (-1 . elem_code) | Element type code (integer). With link lists, always 2, meaning link element. |
| ( 1 . topo_id) | Topology ID of start node (real). |
| ( 2 . topo_id) | Topology ID of end node (real). |
| (40 . fwd_resist) | Forward resistance (real). |
| (41 . rev_resist) | Reverse resistance (real). |
| (70 . link_dir) | Link direction (integer): -1, 0, or 1. -1 = Reverse 0 = Bidirectional 1 = Forward |
