[Haskell-beginners] Crash Course for C++ "Refugees"?

[Mark Santolucito]

Hi Frank,

You are looking for the foreign function interface (FFI) for Haskell.
Googling this will produce no end of _somewhat_ useful results. Basically
you can call Haskell from C and vice versa. I'm not aware of a hs ffi
explicitly for C++, but it is essentially the same/likely short work to do
the C<->C++ interface for any particular application.

http://www.haskell.org/haskellwiki/FFI_Introduction

http://www.haskell.org/haskellwiki/GHC/Using_the_FFI

There is some code that I wrote for an abandoned project that might help
you out at lotusstem.us/ffi.zip (sorry for the random site, the code
somehow ended up on that server and I'm without a laptop to easily move it
now). If i remember correctly I had issues with hsFFI.h so just avoided
using it entirely. Likely not the correct approach but hopefully enough to
get you started.
