I'm not certain of the in-memory representation of a numpy array, but it wouldn't surprise me if it's just a series of consecutive ints/floats - which would be exactly what a C or Fortran library will be expecting. So my understanding is that there's some basic ctypes wrapper code to locate the base address of the array, and then it passes that straight along. Of course, without seeing the code....
