Judging from the source code, it is the distance of the vertex from the
root. (See visitors.c, line 439).
Yeah, printed out the values once again and deduced it. :)
igraph_dfs, that vector will be filled with the parent IDs for each
vertex and I think you can safely use that vector from the
out_callback. (I haven't tried it, though, I'm only looking at the
source code).
Or, I can use one of the vectors in the struct pair from the previous email as the father vector? I'll try it and see if it works.
