[C++-sig] Newbie : fastest way of sending floats

i have joined this list because i need to wrap a big c++ library and i
to use boost.
i'm just at the very very beginning right now. 
i need to wrap a c++ function that takes an array a point coordinates
on the python side, they are built that way :
myList = [ [ 12.23 , 34.34 ] , [ 16.534, 34.8643] , ....    ]
right now, i wrap this function :
void testObject(const boost::python::object& obj)
	boost::python::list list(obj);
	double x,y;
	for(int i = 0; i < 5; ++i )
		x =
		y =
		_RPT3(_CRT_WARN,"point %d = (%f,%f)\n",i,x,y);

And it somehow works

I understand this really looks like horrible code, but these are just
very very very early tests :)

Could you please point me to some information on how to make this

I am not looking for the cleanest code, but for the FASTEST way to pass
the array of floats. I am willing to use the raw C api if needed.
