Geometry Boost List: [geometry] Check polygon features

Subject: [geometry] Check polygon features

I am a newbie using boost geometry library. I installed boost library version
1.56.0. 
I used online example to create a polygon type like this: 

typedef boost::geometry::model::d2::point_xy<double> boostPoint; 
typedef boost::geometry::model::polygon<boostPoint> boostPolygon; 
boostPolygon bpoly; 

then I added couple of point as follow: 

boost::geometry::append(bPoly, boost::geometry::make<boostPoint>(X, Y)); //
--> X & Y are double 

The point is that, my point of creation of a boost polygon is to create a
polygon from my vector of points, then check the following features: 

-if it is a simple polygon? (found solution: if(
boost::geometry::is_simple(bPoly) )   

-What is its orientation (clockwise, counterclockwise)?  ...........ANY HELP
WOULD BE APPRECIATED IN ADVANCE
