Hello, is there an igraph function in C that translates an igraph\_es\_t type to igraph\_integer\_t or igraph\_vector\_t type? I have looked through the documentation but have not a function like that. ---

What would you like to do exactly? An `igraph_es_t` is an edge selector type, it doens’t yield a vector. Using `igraph_eit_create` you can create an edge iterator for a given edge selector. If so desired, you can store the resulting edge indices in a vector while iterating of the edge iterator. But perhaps you would simply like to use the resulting edge indices immediately, instead of first storing them in a vector? ---

I think I understand what I need to do now, thanks for your reply!
