Re: [Haskell-cafe] Opening a file that another process is writing

I want to open for reading a log file that another process is locking for write. I know it's possible, since 'cat' and 'vim' can read that file (but not edit it, of course). How can I do that in Haskell? 'openFile' says "permission denied".

(untested) i think you should open it in shared mode, that is impossible via openFile. but you can open Fd using low-level c_open call and then use fdToHandle procedure -- Best regards, Bulat mailto:Bulat.Ziganshin@gmail.com
