Oh THIS is interesting.  There's a function to opn resources
(RFopen()) but there's no function to actually close the resource
file!  At least none that I can find offhand.  Am I expected to use
FSclose?  If I do that won't that also close the data fork which I
MIGHT want open?

See, I'd like to open both forks independently and close them
independently.  The program I'm working on compares the contents of
resource forks byte by byte.  Interestingly enough, files that are
EXECT duplicates of each other (call them fileA and fileB) have
differing resource contents, at least according to this program that
I've written.

Will resource forks ALWAYS be different between files even when I've
used COMMAND-D to duplicate them from the finder?  Their data forks
are identical, that's no problem.  But their resource forks are always
different.  Wierd.

The Mythos of Dark Hacker:

"Controlled by the sinister and shadowy "suits" Dark Hacker now employs
the tools of computer science to free himself from the suit's will.
By day he is a lackey... but at night when the city sleeps he
becomes.... DARK HACKER!"
