Question

I want to run a subroutine in background and return its value in my program.
So what I do is

 use Proc::Simple;
 $myproc = Proc::Simple->new();        # Create a new process object
 $myproc->start(\&subroutine);         # Launch a perl subroutine

But my subroutine return a value. I first tried using global variables, but it didn’t work.

Does anyone know how I can return a value from a bg process?

Answer 1

I believe the easiest way to do that is to use threads. I can run the subroutine in a thread and use join() to use its return value.
