RE: Exposing C function via Lua

[Asko Kauppi <Asko.Kauppi@...>]

With Lua, you can return multiple values at once, and those can even be
tables. I would do this as (sort-of Lua function prototype):

	ret, a2, a3= LuaM( a1, term, start )

This, of course, assuming that 'a2' and 'a3' are "output only". If you also
want to feed them in, you'll need to add more param tables like 'a1'. 

To do this in practise, you can use e.g. Glua-X library from the wiki. It
allows returning Lua tables from C code. Have a look:

P.S. What's in the 'Array' anyways?
