Does'nt lua_*call functions do it?

------------------------ some lua code ----------------------
function funk()

end
--- If the body of script does not have any code it works
------------------------ some c code -------------------------

luaL_loadfile(L, "test.lua"); // Ok
lua_call(L, 0, 0);  // Works as expected with 1st script (does nothing) 
2nd script fails here

// My first message does not contains following since it failed above
lua_getglobal(L, "funk"); // funk is on top of the stack?
lua_call(L, 0, 0); // Ok, funk being called

------------------------ end of some c code ------------


but... when i run above code with this script, int msg(lua_State *L); 
function gets 0x0 as function address

------------------------ another lua code ---------------
function funk()

end

msg(funk) -- msg will fail to receive address
----------------------------------------------------------------------

so lua scripts can't register their functions as callbacks :)
