Re: Threads

Hi guys,

threads = []

list = %w(aS, bS, cS, dS, eS, fS, gS, hS)

for space in list
threads << Thread.new(space) {|numericalSpace|
while 1
puts "#{Thread.id}: #{numericalSpace}"
sleep 2.5
end
}
end

Yes, there was a bug in my code, that being a typo of thread.id (should be Thread.id), but the biggest thing, was the fact that I needed to do a thread join. So I added this:

threads.each {|eachThread| eachThread.join}

Now on to signaling!

Cheers, Phy

I think your code still isn't quite what you want. Try

require 'thread'

threads = []
mutex = Mutex.new
STDOUT.sync = true

list = %w(aS, bS, cS, dS, eS, fS, gS, hS)

for space in list
threads << Thread.new(space) {|numericalSpace|
while true
mutex.synchronize do
puts "#{Thread.current.object_id}: #{numericalSpace}"
end
sleep 2.5
end
}
end

threads.each {|eachThread| eachThread.join}
