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. :)

dont worry.. some of us actually hold back from hitting the send
button after writing comments like that :P it gets to you when
you start to realize that people dont RTFM or even *try* looking
for a solution to the problems they have before they post here.
> Isn't this one of the purposes of this list?
not to ask questions that are readily available in the knowledge
base, documentation etc.. you use the dev list to bring up issues
that are not documented (in my opinion).. mostly, topics discussed
here end up translated to the knowledge base eventually.
i think its just a purpose of "hey, i cannot be bothered checking"
and wola.. people post anyhow..

you know, *you* manage your pointers.. if you free a pointer,
then set the pointer reference to NULL afterwards.. then a
simple check if it is NULL will be sufficient.. you can also
check lock counts on handles if you want to go that far :)
> BTW, thanks to those who did respond.
look for the Mem* API routines.. :)
if i sound abrupt.. thats just the way i am after flying from
USA and heading straight into email at 7am :) excuse me :P
