in reply to Introduction to Parallel::ForkManager
I am using the parallel fork manager module to start 4 processes in parallel.I want the output of those 4 processes for doing some operations like writing into a excel/text file. I assigned the output to variables but i am unable to acess those variables after pm->finish command(out side the for loop).
please explain me the simple way to retreive data from child processes so that i can acess those output even after the child process exits. I have gone through that cpan module but didnt get exactly what to do
