Hello,
(on unix) creating a process A which spawns itself a subprocess B and
terminating process A before it finishes leaves process B as a process on its
own. This is because "terminateProcess" sends the sigterm signal to the
process only and not to its process group.
Is there a way to terminate the process group of process A? Or alternatively
is there a way to get he Posix ProcessId of process A?
The following is a minimal example. The process "sleep 60" survives the
termination of both "sleep" and of the main program.
<code>
module Main where
import Control.Concurrent
import System.Process
main = do
h@(_, _, _, hProc) <- createProcess (proc "time" ["sleep", "60"])
threadDelay $ 5 * 1000000
terminateProcess hProc
waitForProcess hProc
</code>
Kind regards,
André
