[Pyrex] Creating a DLL with Pyrex.

The Background: I'm trying to create a Palm Conduit using Python.
I've currently got it working using Palm's COM API, but that solution
is not portable across platforms, so I'ld like to switch over to
Palm's C API.
The Problem: I think I've learned enough to be able to wrap the
necessary parts of the C API using Pyrex, but in order to get the
conduit installed, I need to turn it into a DLL which exposes the
following entry points:
ExportFunc long GetConduitInfo(ConduitInfoEnum infoType, void
*pInArgs, void *pOut, DWORD *pdwOutSize)
ExportFunc DWORD GetConduitVersion() and
ExportFunc long OpenConduit(PROGRESSFN pFn, CSyncProperties& rProps)
I believe that py2exe will be unable to help me in this task, since it
doesn't have the ability to specify the C signatures of the funtions,
and to the best of my knowledge, there's no type-library/interface
concept for dlls, as there is for COM servers. Pyrex seems like it
will let me specify the C signatures, but I can't see any way to add
in automatically generated code
From what I can see on this page:
http://www.freenet.org.nz/python/embeddingpyrex/ it seems like it should
be possible to create a DLL, at least in theory, but I'm fairly lost as
to how I would actually go about it. Can anyone point me at some
documentation, or sample projects, or tell me that it can't currently be
done, and point me at the appropriate source file to hack in order to
get it working, or if I shouldn't do it, why not?
Thanks,
Blake.
