Can you send me a working example for 5.2? I try to push a table with 
function pointer
to call them in my script. I try to create this:

       lua_newtable(m_lua);
       luaL_setfuncs( m_lua, &l_functions[0], 0);
       lua_pushvalue(m_lua, -1);
       lua_setglobal(m_lua, p_libname.c_str());

but in my script I can not call any of my functions (they don't exist). 
I would like to put
a set of "global functions" to the script.

Thanks
