[Haskell-cafe] Binary file r/w example

[Bo Herlin]

Yes, I am, and the IOExtension module IS one of my problems.
The other problem is that I am interested in this Ptr thing, and I 
havent seen any examples in using it, and is seems like Ptr is not in 
any of my Haskell-books or in any of the tutorials that I have found.
