Subject: Passing a string as stdin to a popen

Say I have some content in a ruby string and I want to pass it as
stdin input to a command. I then want to read the output.

I tried this:

IO.popen("mycommand", mode='r+') do |io|
  io.write mytext
  result = io.read
end

This resulted in a "Broken Pipe" exception. What's the correct way to do this?

Thanks,

Pedro.
