Function Documentation

ownObjDescQueueExtractBlockedNodes()

vx_status ownObjDescQueueExtractBlockedNodes	(	uint16_t	obj_desc_q_id,
		tivx_obj_desc_queue_blocked_nodes_t *	out_blocked_nodes
	)

Extract nodes blocked on this object descriptor queue ID.

Adds to out_blocked_nodes, make sure out_blocked_nodes->num_nodes is set to 0 before calling this API
