Re: Proc::Simple store return from background processby Perlbotics (Bishop) |

Short answer: You cannot with Proc::Simple (longer: in your case when starting a sub{...} as a child process) This is what happens in the child part of the fork() that is executed for your $func = sub{...}; So, the exit 0 (successful execution) is all that is returned from your sub{...}. The $return value is discarded.
Your sub{...} could return the result to the main process by means of IPC or
by storing the result in a temporary file
(e.g. YAML, JSON, Storable, etc.). The parent process could read
the result from a pipe or load the serialised data from a file after the sub has finished.
However, I guess, that in this particular case, you're better off with threads and maybe a queue.
