I am writing an application on Windows XP using ghc 6.10.1 that manages
test cases (same applies to ghc 6.8.3). For each selected test case, the
application runs an executable associated with the test case using
System.Process.runInteractiveCommand. These processes have to be aborted
in some cases, for example, when their specified termination time is up.
As I realized, however, aborting these processes using terminateProcess
is not reliable. Most often, the processes do not terminate correctly
but have to be killed from the Windows Task Manager. In some cases, the
process still produces output - in particular if I apply
getProcessExitCode on the process just killed. By the way: calling and
killing the process from the shell with Ctrl-C successfully kills the
Any advice on how to reliably terminate a process on Windows?
