[igraph] Detecting a single edge between nodes

[Thomas Gorochowski]

Hi there,

I am trying to efficiently come up with a method to detect if there is  
a edge directly between two node v1, v2. At the moment I am using the  
following but was wondering what the most efficient method would be  
where I don't have to effectively remove the error handler.

igraph_integer_t eid;
igraph_set_error_handler(igraph_error_handler_ignore);
if (igraph_get_eid(G, &eid, v1, v2, directed) != 0)
  return TRUE;
else
  return FALSE;

Many thanks,

Tom
