[Boost-users] [BGL] std::pair<edge_descriptor, bool> edge()

Dear all, Am I right in believing that the bool returned in the function below is meant to signal to the user whether there is an edge between u and v or not? std::pair<edge_descriptor, bool> edge(vertex_descriptor u, vertex_descriptor v, const adjacency_list& g) The only explanation that the online documentation provides for this function is: "Returns an edge connecting vertex u to vertex v in graph g." Perhaps somebody should amend that explanation... Best, --Hossein
