Hi.
After having read http://book.realworldhaskell.org/read/concurrent-and-multicore-programming.h...
I have a doubt about Data.ByteString.Lazy.
Why getContents function don't use pread (or an emulation, if not available)?
Why would it?
So that you don't need to open the same file multiple time: http://book.realworldhaskell.org/read/concurrent-and-multicore-programming.h...
We are constrained here by the semantics of Handle which requires that getContents semi-close the Handle (which in turn is to make it harder to shoot yourself in the foot while doing lazy IO). Duncan
