Re: Returning data from C functions called using "loadlib".

[Rici Lake <lua@...>]

If what you mean is:

  local a = 3
  cfunction(a)
  -- now a has magically become 5

Then you can't do it, in Lua or any sensible language ;)
(Well, we all have our biases.)
In Lua, all arguments are passed by value.

Do this:

a = cfunction()
