Hi all! Today i was reading System.IO and didn't manage to understand how it works just by reading it. I looked the internet for some help on this, but only "advanced" information is available. Can anyone show me how to use openBinaryFile ? Just an example, like opening file "somefile" and separating it into something that can be edited in the code (like 8 bit words) then go to word nr12 and edit the last bit? Thanks!

http://haskell.org/haskellwiki/Binary_IO For flat lists of bytes, use Data.ByteString, for structured data, try NewBinary. There are other options too, documented above. openBinaryFile just sets the line ending handling on windows. I don't think it does what you think it does. -- Don

you can also use hGetBuf and pointers machinery -- Best regards, Bulat mailto:Bulat.Ziganshin@gmail.com
