Interaction between C++ and Rails applications - c++

Question

I have two applications: c++ service and a RoR web server (they are both running at same VPS)
I need to "send" some variables (and then do something with them) from each other. For exaple, i'm looking for something like this:
// my C++ sample
void SendMessage(string message) {
SendTo("127.0.0.1", message);
}
void GetMessage(string message) {
if (message == "stop")
SendMessage("success");
}
# Ruby sample
# application_controller.rb
def stop
#m = Messager.new
#m.send("stop")
end
I have never used it before, and i even don't know which technology should i search and learn.

Answer 1

Ok, i have found the solution. Its TCP sockets:
Ruby TCP server, to send messages:
require 'socket'
server = TCPServer.open(2000)
loop {
Thread.start(server.accept) do |client|
client.puts(Time.now.ctime)
client.puts "Closing the connection. Bye!"
client.close
end
}
Ruby client, to accept messages:
require 'socket'
host = 'localhost'
port = 2001 # it should be running server, or it will be connection error
s = TCPSocket.open(host, port)
while line = s.gets
puts line.chop
end
s.close
Now you should write TCP-server+client in another application. But you have got the idea.
