Bobby,
I think part of the problem may be that there is NO difference between a
valid pointer and a valid number. So you'd never really be sure that what
_could_ be a valid pointer actually _was_. It might be just a number that
happened to be the same range as a valid pointer. Or handle. Or text. Or
garbage.

Thanks for you reply. Not to start a flame war or anything, but I'll state
this again, my question was not an issue of if I had a now defunct pointer
or not. As an exercise, I was examining system Features and I was trying to
discover if there was a known mechanism for determining what is a valid
pointer and what is not. Not pointers I've generated, but ANY pointer,
specifically pointers stored as Feature values. I DID look into this
problem before posting. There is no documentation or knowledge base
articles covering this domain. In fact, I spent the better part of two days
trying to work out a solution on my own. And yes, I have over 2 years of
Palm OS development and I do know the basics of good coding practices. I
even know how to manage my own pointers. :) But by your own words, this
falls into the category of "issues that are not documented". When I had a
road block, I thought to myself: "This would be a good question for
palm-dev-forum..." Like I said, tough crowd. :)
