[igraph] Help with the igraph_diameter(...)

[Richard Geddes]

Hi,

I'm trying to get the path for the diameter of a graph and get segfault
errors when I use the following


---
igraph_t graph;
igraph_integer_t diam, pfrom, pto;
igraph_vector_t* path;

igraph_diameter(&graph, &diam, &pfrom, &pto, path, false, true);

---

however if I use:

igraph_diameter(&graph, &diam, &pfrom, &pto, NULL, false, true);

the execution is normal

the docs say to use an uninitialized vector pointer for path.  Did I
miss something?

using the latest development version of igraph.
