When I look at this file with depends.exe, I can see the C API entry  
points.  The liblas_i contains the implib for liblas.  Is this what  
you are looking for?

Mateusz,

This makes sense right?  &(reader->GetPoint()) is going to get the  
address of the reader's current point?   The Python API uses  
GetPointAt (C API) and it seems to work ok.
