Calling Lua function from C

[Max Ischenko <max@...>]

Hi,

I have a function in Lua that returns a function value:
function foobar()
 return loadstring('2+3')
end

I'm trying to call the foobar from C and to save returned value (to be
able to call it later).
How am I supposed to do this?

   lua_pushstring(L, "foobar");
   lua_gettable(L, LUA_GLOBALSINDEX);
   lua_call(L, 0, 1);

   lua_tocfunction(L, -1); // returns NULL
   lua_typename(L, lua_type(L, -1)); // prints "function"

Is there a way to store a Lua function as C object (and call it) or I
should be using some other way?
