Detects if a route between any 2 nodes can only be found when going in one of the directions. The links with the problematic oneway restrictions are identified. In the example below it is only possible to drive away from the blue area, since all oneway restrictions point in the same direction. The function would identify the 6 links with oneway restrictions. These are not fake data, but from a commercial database!
The result for each link can be saved with ResultSaveLink or ResultGetLink:
0 = No problem
1 = Problem
Returns the number of problematic links.
Possible error codes: -10 -43
