Subprocessing with popen or popen3?

Ruby
1

Currently I have a class MyServer that extends IO, and then I call:

server = MyServer.popen(COMMAND, 'r+)

The only problem is I need to separate stderr and stdout. I contemplated
popen3, but I don’t see how I can make it associated with an object,
which I need in the program. And in addition, it seems to lack a way to
get the pid.

I could theoretically create the stderr, stdout and stdin within the
MyServer class at initialization for popen3, but then I can’t use the
pid to kill the process when I call the shutdown method. Any ideas?

You might find my framework “rexec” useful:

RExec [Orion Transfer Wiki]

More specifically:

RExec::Task

rexec can help you make a daemon:
