Is there any way to get current position from System.IO.Handle as Integer? If no, what other <b> windows/unix portable</b> IO function set of file io with this functionality you can suggest? keeping track of current position by hand is not an option, sorry. I'm thinking about c's low-level functions such as open, read, write, but there is no such functions in windows and I do not know if libc from haskell platform provides emulation. If it does, I'll use lowlevel c functions brainfree.
