calling table:function from c/c++

["pion1013" <pion@...>]

Hi,

I wrote a short lua program like this:


-- test.lua
test = {}
function test:fn (num1, num2)
  return num1 + num2
end


now, I wanted to call this function from c/c++,


lua_State *L = lua_open(0); 
lua_baselibopen(L); 
lua_dofile (L, "test.lua");  
lua_getglobal(L, "test:fn");
lua_pushnumber(L, 100);
lua_pushnumber(L, 200);
lua_call(L, 2, 1);
printf("result : %d\n", (int)lua_tonumber(L, -1)); 
lua_close(L); 


which doesn't work. The program complains about calling nil function. 
My rough guess is that the function "test:fn" belongs to the 
table "test", and not globally known. But, I don't know how to 
correct it.

Can anyone help me, please?
