Wow, tough crowd! Not to be defensive, but I don't think my question was
silly at all. Perhaps the wording could of been improved, but it's a valid,
non-trivial request for information. Isn't this one of the purposes of this
list? There is no MemIsValidPtr()-type of function, and would rather not
make assumptions based upon a given value. That is, I would like to be
able to test a given address for validity before riding off the deep end.
People tend not to like applications that causes your device to reset.
Given the level of expertise on this list, I was hoping that there was
someone who has already faces this particual problem. Obviously, testing
for NULL is not adequate.
BTW, thanks to those who did respond.

(Yes,
