Hi Marco,

Use igraph_get_eid to get the edge ID based on the two endpoints.

Hi all,

I need to select an edge in a graph (then the code will cycle and I will
select edges according to the cycle), using the C library, based on the
nodes the edge is incident to.

I see from the doc that there is a function called:

igraph_es_fromto(igraph_es_t *es, igraph_vs_t from, igraph_vs_t to);

which, according to the doc, is not implemented yet.

Is there any other way to do this?

In my code, at some point, I need to access the attribute of an edge
which is the one connecting the two nodes I am considering (actually,
between the node I am considering an one of the adjacent nodes).


Thank you,
