DT dt;
Vertex_handle vh = .. ;

DT::Face_circulator fc = dt.incident_faces(vh), done(fc);

// Now we walk counterclockwise around vh

do {
Face_handle fh = fc;  // not really needed. You can replace fh by fc in what 
follows
int i = fh->index(v); // is is such that fh->vertex(i) == vh holds
Vertex_handle  other = fh->vertex(DT::cw(i)); // The clockwise neighbor of v 
in the face
}while(fc != done);
