The two first work. Their documentation pages are here:
http://www.cgal.org/Manual/latest/doc_html/cgal_manual/Straight_skeleton_2_ref/Function_create_interior_skeleton_and_offset_polygons_2.html
and there:
http://www.cgal.org/Manual/latest/doc_html/cgal_manual/Straight_skeleton_2_ref/Function_create_exterior_skeleton_and_offset_polygons_2.html

You might want to have a look at this chapter which explain how to
get offsets with no sharp angles:
