Re: Reliable invalid pointer check

[Henk Jonas]

Why do you do it? It will never work. Pointer checks are useless in my eyes. The only reliable pointer check is maybe NULL and even this could be wrong in certain systems. It's just a senseless??? work.

Well, I have tried several techniques to test the pointer. I coded up a
routine that looks at the chunk and examines several flags. Warning: If
anyone does this the Endianess is wrong (from a 68k perspective). You need
to byte swap several values to make this work.
