How to pass a table as a parameter?

["jose_marin2 <jose_marin2@...>" <jose_marin2@...>]

Hello!

Im trying to do this:

in Lua:

-----------

function CreateObject()
 local Object = {}

 function Object:DoSomething()
 ...
 end

 return Object

end

function func(obj)

 obj:DoSomething()

end

theObject = CreateObject()

SetEventFunction(theObject, func)

-----------

In C, I must call "func", passing as parameter the table 
("theObject").

I know how to get the address and call func(via lua_getref), but how 
to get the address of a table, and pass it to the function call?
