// Small code snippet on how to extract the length of each link of a road-network.

// First, add the following two lines at the top of User.c:
#include "road.h"
tRoadLinkInfo MyRoadLinkInfo;
// This creates a new tRoadLinkInfo to store information at a later point.

// Then, add the following code in the function User_TestRun_Start_atEnd
int
User_TestRun_Start_atEnd (void)
{
    if (SimCore.IsRegularInit) {
    // should not be called at first initialization of Application
    
        int number_of_links = RoadGetLinkCount(Env.Road);
        Log ("The number of links is %i\n", number_of_links);
    
        double link_length[number_of_links];
    
        int ObjID_of_link;
    
        int i;
        for (i=0; i < number_of_links; i++) {
    
            ObjID_of_link = RoadLinkIdGetLinkObjId(Env.Road, i);
            // the objectID of each link is required for the function RoadObjIdGetInfo()
            RoadObjIdGetInfo(Env.Road, ObjID_of_link, ROT_Link, &MyRoadLinkInfo);
            link_length[i] = MyRoadLinkInfo.len;
    
            Log ("The length of link #%i is %.3f m\n", i, link_length[i]);
