Userdata and deleting...

["Kenk" <kenk@...>]

Hi there,

   I'm just looking for a 'best-practice' scenario here... Say I've got 
user data all setup and Lua's happily using it. If for whatever reason that 
user data becomes deleted in C code (for example, a window closing, or a 
routine called that deletes an element in the collection that Lua happens to 
have a reference to somewhere else in script).... What's the best way of 
setting this userdata to nil in C and then telling Lua it's no longer 
around? In script I'd set the variable to nil... Not sure how I'd go about 
that from C.

Thanks!
