next_up Struct Reference

---

Detailed Description

Structure produced by dq_fill_next_up, representing the nodes to which we could send the query, along with routing information to be able to favor UPs that report a QRP match early in the querying process.

Because we save the last array of nodes computed and sorted at each invocation of the querying steps (to avoid costly calls to the qrp_node_can_route() routine if possible), we store both the selected node ID (nodes can disappear between invocations but the ID is unique) and cache the result of qrp_node_can_route() calls into `can_route'.

Data Fields
gnutella_node_t *	node
	Selected node.
guint32	nid
	Selected node ID.
query_hashvec_t *	qhv
	Query hash vector for the query.
gint	can_route
	-1 = unknown, otherwise TRUE / FALSE
gint	queue_pending
	-1 = unknown, otherwise cached queue size
