Best way to find out to what userdata is on the stack?

[Lothar Scholz <mailinglists@...>]

Hello,

This is a newbies question: If i create multiple userdata objects,
what the best way to find out if that userdata pointer that i get from
the stack belongs to my "Foobar" c struct.

At the moment i'm using an hash table for all my own userdata,
lookup the pointer there and if found i get a verification that this
userdata is really a "Foobar" struct.

Is there any better way ?
