Can I modify eg array structures without copying into the Lua stack?
Yes, I think the simplest way, assuming your array structure won't got out of scope during the life of the Lua state, is to use a light user data (the address of array) stored in a c closure for each operation you want to perform on the array. One for get and one for set I imagine?
Yes and the function call.
You would then call your script with the closures (functions) as arguments.
Seems to be a nice feature, because I would like to pass linear algebra structures to the script and the script should modify, so I don't need to copy the data first and copy the return back into the structure and I don't create any duplicated memory.
Thanks for your explanation
Phil
