[ODE] help in Get functions

[Joao Pinto]

I am a newbie with ODE and cpp for that matter, so my question can be very stupid, anyway I can't seem to sort it out.
   
  I have made a very simple program that only creates a world, sets a gravity vector and creates an object at a specific location. Then I use the dWorldGetGravity and dBodyGetPosition functions to check if the changes where actually made in the simulation. However, when I cout to the screen the results of the vectors only the 1st position is actually changed. The rest still has my initialization data. This happens in the gravity vector as well as in the pointer of the position.
   
  Can anyone help me...? I'm sure this is a very basic stuff...
   
  Thank you very much

  here is the code:
   
  //*******************************************************
   
  using namespace std;
  int main(int argc, char *argv[])
{
        
    dReal x, y, z;
  
      //init values to be updated with the real values in the world
    gravity[0]=1111111.;
    gravity[1]=1111111.;
    gravity[2]=1111111.;
  
    world = dWorldCreate();
  
    dWorldSetGravity (world,x=1.,y=2.,z=3.);
      body1 = dBodyCreate (world);
    dBodySetPosition   (body1, 1., 2., 3.);
      const dReal *pos = dBodyGetPosition (body1);  
    cout << "\n\npos " << pos[0]<< "\t" << pos[1]<< "\t" << pos[2];
      
    dWorldGetGravity (world,gravity);
      cout << "\n\ngravity: " << gravity[0]<< "\t" <<gravity[1]<< "\t" <<gravity[2] << endl << endl; 
      dWorldDestroy (world);
      system("PAUSE");
    return EXIT_SUCCESS;
}
