Re^3: Question about Parallel::ForkManager

I didn't realized it used the disk. Pipes could be used, so I'm curious why it uses the disk. (Ah yes, using pipes would prevent the parent from doing other work while the children are running. This is usually not a problem, but it would break P::FM's interface to support this.)

There won't be a race condition. It surely defends against that using the process id in the file name.

Maybe I can do something simple with "fork" and pipes? If you have a solution could you give it to me.	[reply]

It's not pipes, but look at Re^6: forking with Storable and IPC::ShareLite, the second code example uses IPC::Shareable. For a basic forking with pipes, see Re: controlling child processes for example. I'm not really a human, but I play one on earth. Old Perl Programmer Haiku ................... flash japh	[reply]

I don't have that handy, no. If you're ok with a solution that uses threads, I can provide that.	[reply]
