[SciPy-dev] Combining Numpy/C/fortran ?

Folks,
I'm trying to write an interface to numpy for a piece of mixed C/fortran code, 
and I'm getting nowhere fast. 

Roughly, the code is organized as such: a first C file defines some base 
structures (involving long and double arrays) and initializes their members 
by calling Fortran routines, either directly or through a set of C functions 
defined in a second file. I need to get access to the initialized structures.

I first started to get rid of the C structures by redefining them in Python, 
so that I would only have to call functions with array arguments (and not 
structures) and use f2py for the interface. However, this is not exactly a 
bug-safe approach. The best would be to get an interface Python/C structure, 
so that I could send ndarrays as inputs and get ndarrays as outputs.

What is the easiest way to write such an interface ? 

Thanks a lot for any idea...
