Re: C++ integration / DSEL alternative questions

Open a new state

Push your c functions in there, similar to where you open the standard libs

Push and call your lua script

That ought to work.

Sort of.
There's three weak reasons:
1) I don't know (yet) how the regular C API Bindings work and only
intend to find out if ffi is indeed the problem.
2) LuaJit docs suggest that ffi bound functions are a lot faster as
they are subject to JIT optimization
3) I wanted to try the easy way first.

If there's reason to believe that C API Bindings will work in the same
scenario I'm happy to give that a shot and learn it.

Thanks,
