After using forkProcess the child cannot read from stdin (except for data already in the buffer). Using forkProcessAll or foreign importing C's fork makes the problem go away. This applies to Solaris and GHC 6.0, I have not tested other platforms.
Example program: > module Main where > import Monad > import IO > import System.Posix > main = do > mPid <- forkProcess > case mPid of > Nothing -> -- Child. > forwardStdin > Just pid -> do -- Parent. > getProcessStatus True False pid > return () > forwardStdin = do > eof <- isEOF > when (not eof) $ do > c <- getChar > putChar c > forwardStdin Test output: $ echo "apa" | ./Test apa $ ./Test asdfasdf ^CTest: interrupted $ /NAD _______________________________________________ Glasgow-haskell-bugs mailing list [EMAIL PROTECTED] http://www.haskell.org/mailman/listinfo/glasgow-haskell-bugs
