You need to use the function:

Halfedge_around_vertex_circulator

v.incident_halfedges ()

Hello,

I am using the Arrangement_2 package of CGAL 3.4 release (with Visual C++ 2005
under Windows XP SP3). In a function, i am searching for the vertex associated
to a particular input point . I iterate through all the vertices of the
arrangement and found that vertex. Here i am not using the point location
strategies because i'm sure that the searched point is associated to a vertex
of the arrangement. But when i try to access the incident halfedge via the
member function halfegde:

Vertex_const_iterator vit; // The found vertex
Halfedge* h = vit->halfedge();

I have the follwing error:
Error   6       error C2248:
'CGAL::Arrangement_on_surface_2<GeomTraits_,TopTraits_>::Vertex::halfedge' :
cannot access private member declared in class
'CGAL::Arrangement_on_surface_2<GeomTraits_,TopTraits_>::Vertex'
c:\source code\my_code.h        506

In my function, i am trying to obtain the face whose outer ccb contains the
vertex i am searching. So i must find the halfedge incident to the vertex
(since the Vertex type does not offer a direct mean to obtain that facet) and
then use the face() member function of the incident halfedge to get the face i
am seraching for.

Thnaks in advance for your help.
