At the following URL

There is the following code

#!/usr/local/ruby-1.8.0/bin/ruby  
require ‘ftools’  
require ‘tempfile’

def compete who, f  
5.times do |i|  
f.flock File::LOCK\_EX  
f.puts format(“%s:%d @ %f\n”,who, i, Time.now.to\_f)  
f.flock File::LOCK\_UN  
end  
end

path = format( **FILE** + ‘.out’)  
fd = open(path, File::WRONLY | File::TRUNC | File::CREAT)

if fork  
compete ‘PARENT’, fd

Process.wait rescue nil  
open(path){|f| puts f.read}  
fd.close  
File.rm\_f path if File.exist? path

else  
compete ‘CHILD’, fd  
end

The code runs on my system. But, I don’t see any call to Tempfile.new.  
I’m assuming it’s implied? If it is being implied, where is it being  
implied at in the code?
