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()

Ok, I have a problem.
I am calling functions in an external library that
i've written in C. I initalise this library using the
"loadlib" function in lua.
I call these C functions fine, and pass data to them
fine.
However what i want is to send data to the C functions
via params to the C functions (i can do this already),
then the C functions to manipulate that data so that
the original data passed from the lua script is
changed.
I am really out of ideas.
Thanks, I hope you can help,
Aaron
