launch process, retrieve PID, and Exit Status
At the same time? PID belongs to a running process; exit status is an int returned by terminating main(). Unless I've mistaken, you can't have both meaningful at the same time: when you have the exit status, the process is already terminated.
Anyway, have a look at
IPC::Run. Other method is to
pipe (thus you can read STDOUT),
fork (thus you get the PID),
exec then
waitpid in the main procss (and then use
$? to get the exit status).
Sorry if my advice was wrong.
