I'm in the habit of clearing my memory blocks as soon as I'm finished with
them. The above information raises a couple of questions (here I'm
assuming we are using a res handle unique to our use that no one else will
be using):
1. What happens if you call RELEASERESOURCE on a handle that's designated
as non-purgeable? Will it still release the handle from memory?
2. What happens if you call RELEASERESOURCE on a handle that's already
been purged? Will your system crash or will you just get an osErr?
TIA.
