How to broadcast and recieve a messaage in a Cluster?

vigneshinbox · 04-09-2009, 03:59 AM

I am designing a system which will broadcast a message to all the nodes in a cluster.And the receiving node should send a feed back to the broadcasting node.When i get a single feedback from any of the receiving node, the broadcasting node should stop receiving the feedback.With that feedback i am doing some operations.This both actions should be implemented in a single program.As i am new to socket programming i don't know how to do tat.Can someone give me the code for this???
Thanx in advance

You should buy this book: http://www.kohala.com/start/unpv22e/unpv22e.html

Also on that page, is a link to the source code provided in the book. You should hopefully be able to find your answers there.

P.S. An example of a broadcaster and a receiver

Code:

#include <Socket/UDPSocket.h>

int main()
{
  socketpp::UDPSocket sock;
  sock.EnableBroadcast();
  sock.Send("hello world", 11, "255.255.255.255", 8000);
}

Code:

#include <Socket/UDPSocket.h>
#include <iostream>

int main()
{
  socketpp::UDPSocket sock;
  sock.Bind(8000);
  char msg[80] = {0};
  sock.Recv(msg, sizeof(msg) - 1);
  std::cout << msg << std::endl;
}
