Calling a function on exit

[Bernhard Bliem <bernhard.bliem@...>]

Hello,

I've written a little wrapper to use SDL from within Lua scripts. When I 
use SDL with C, I usually call atexit(SDL_Quit) after I initialized it. 
I have to call SDL_Quit on exit, because bad things could happen if I don't.
However, since I initialize SDL in Lua, I have to make sure SDL_Quit 
(i.e. my wrapper function for it) gets called whenever the chunk 
execution ends. If there is an error in my script and it aborts, the 
program terminates without calling SDL_Quit. Is there some kind of 
"atexit" function for Lua? I have looked at hooks, but they don't seem 
to be made for this purpose. Unfortunately it is not an option to check 
if SDL_Quit has to be called by the interpreter after the script 
execution has ended.

Regards,
Bernhard
