Thanks for reminding me about this. The easiest solution for SciPy itself
would be to
declare all the function pointers as public and have Cython generate a
header file to
go along with the module so that C and C++ modules could use the
declarations with
less effort. I worked on that a little, but ran in to some trouble getting
complex types
to work properly. I'll revisit that in the next few days and see if I can
get it working.
I don't currently have a full working example on hand, but I'll get back to
you if I get
a good one put together.
