Re: Is it safe to call getProcessExitCode more than once?

Both [waitForProcess and getProcessExitCode] will throw an exception if the process terminated on a signal.

So if I terminate a process manually, I'll have to wait for the ExitCode to avoid a zombie process, and waiting for the ExitCode invariably throws an exception.

Or do I misunderstand something?

No, that seems correct. Although, depending upon the OS, setting SIGCHLD to SIG_IGN may cause processes to be reaped automatically (i.e. not become zombies), so that's a possible alternative. -- Glynn Clements
