Re: Tasking children from a single pipe

In order to effeciently use all the children, I want each child to only take one "task" from the pipe, leaving the next child to pickup the next "task". The work data is separated by a newline, and each child reads up to the first newline it encounters.
...
What would you do?

I would write a magazine article about it, probably.

I thought that managing a pipe for each child would be unruly, but your example provided me with the information I needed. Specifically maintaining a hash of pipes associated to each child PID was what I was looking for. IO::Pipe provided the handle reference I needed to do that. How could I have taken a reference to a FILEHANDLE like: `pipe( READER, WRITER ); $pipes{$pid} = [\READER, \WRITER];` [download] Would that be the same thing as using IO::Pipe?	[reply] [d/l]

pipe( READER, WRITER );
