Click here to show extra information the analyzer produced.

```
The following graphviz dot graph describes paths through the callgraph that could lead to a function which writes a pointer argument:
digraph G {
"(AddContactToList, 1)" -> {}
}

No path was found through the callgraph that could lead to a function which passes a pointer to third-party code.
