Can this be done, or do I SC> need to start with an actual file? add the following to fastio.c: void* openStdin() { return stdin; } and this to FastIO.hs: openStdin :: IO Handle openStdin = do h <- c__openStdin return (H h) foreign import ccall "openStdin" c__openStdin :: IO (Ptr ()) btw, id this is a test for shootout - is using C code acceptable? this way you can rewrite the whole program :) -- Best regards, Bulat mailto:bulatz@HotPOP.com
