You can't. At least not without diving into internals, which is
strongly disrecommended. The classic Lua/C API and FFI cdata
don't mix well.
Presumably, you're using LuaJIT for its speed benefits. These are
almost completely negated by using a) the classic Lua/C API and
b) SWIG or other binding generators.
If you don't want to rewrite your C bindings and/or you haven't
benchmarked whether the code on the Lua side is actually CPU
intensive, then better stick with plain Lua.
