How to get the predecessors of vertices in the shortest path obtained in nvgraphSssp()?

Hi, it seems that nvgraphSssp() only provides the shortest path distance, not the path itself. How can I get the predecessors of vertices in the shortest path obtained in nvgraphSssp()?

can’t you get this in the traversal API?
