Description
QueryAtTurns returns an array of adjacent turns and their weights. The array has adjacentEdgesCount entries, where adjacentEdgesCount is the value returned by IForwardStar::FindAdjacent.

Remarks
A turn represents a movement between two adjacent edges, the from-edge and the to-edge. If you are querying turns, you must specify the fromEdgeEID in the IForwardStar::FindAdjancent request. This is from-edge of the turn.
adjacentTurnEIDs and adjacentTurnsWeightValue are arrays that are dimensioned to at least adjacentEdgesCount , as returned by IForwardStar::FindAdjacent . Note that the MaxDegree property of INetwork will tell you the maximum number of edges for any junction, and you can use this to allocate memory for these arrays. Count is equal to adjacentEdgesCount from IForwardStar::FindAdjacent.
