should_connect_tunnel_to()

enum GNUNET_GenericReturnValue should_connect_tunnel_to	(	size_t	count,
		size_t	src,
		size_t	dst
	)

Returns GNUNET_YES or GNUNET_NO to determine if the peer at index src should or should not connect outgoing to the peer at index dst to construct a complete basement with a given count of peers.
