[C++-sig] dumb policy question

[Grant Goodyear]

I'm currently in the process of modifying some C code so that it can
be accessed from python using boost.python.  I've attached ref.h and
libpyref.cpp (and doref.cpp as a test program for ref.h), and I'm hoping
some kind soul can tell me what I need to do to get this simple snippet
to work correctly.  Right now I get the following:

In [1]:import libpyref

In [2]:ints = [0,0,0,0]

In [3]:libpyref.ref(ints,2)
---------------------------------------------------------------------------
Boost.Python.ArgumentError                             Traceback (most
recent call last)

/home/grant/EMAN2/playground/<console> 

ArgumentError: Python argument types in
    libpyref.ref(list, int)
did not match C++ signature:
    ref(std::vector<int, std::allocator<int> > {lvalue}, int)

I'm not sure if the problem is the policy, or that I need some sort of
typeconverter because what I'm asking is beyond the magic converters
already in boost_python?

Thanks,
Grant Goodyear
