See the docs for Curve Objects:
blender_python_api_current/bpy.types.Curve.html
take for example this Curve Object, which consists of three sub curve, 1 of which is a closed curve. Run this with the Curve Object in Object mode.

HI... welcome back! :P sorry.. "fast" question... some ref in order to get the coordinates form curve control points???? thanks for any advice :D
