Collecting Exe printf outputs from system call in Ruby

Question

I want to store the printf output of an exe file that I call by system(foo.exe) in ruby and get the exit status. How would I do that?

Open3 is the best way to do this.

require 'open3'
Open3.popen3('foo.exe') do |stdin, stdout, stderr, thr|
  status = thr.value
  output = stdout.read
  errors = stderr.read
end
