executing functions from file, without using luaL_dofile

[jseb <gmane2010@...>]

Hello,

I'm trying to load a Lua script from a C file, without executing it at 
load time.
In other words, i don't want to use "luaL_dofile (L, script.lua)".

So i use instead "luaL_loadfile (L, "script.lua") "

But after loading the script file, how can i execute "foo" function from 
inside it ?

i tried this:

    lua_getglobal(L, "foo");
    lua_pcall (L,0,0,0); //compile function
    lua_getfield (L, LUA_GLOBALSINDEX,"foo");
    lua_pcall (L, 0,0,0); //execute function

but the function is not executed.


Thank you.
