title: How can I use poll to accept multiple clients? (TCP Server) (C)
body: <p>This polling business seems like it was written by a madman, and I am unsure how to use it to allow for multiple clients to connect to a server and then send their input to all other clients. </p>
  
  <p>So if I want to have three clients going, I will need something like:</p>
  
  <pre><code>  ufds[0].fd = sd;
    ufds[0].events = POLLIN;
    ufds[1].fd = sd2;
    ufds[1].events = POLLOUT;
    ufds[2].fd = sd2;
    ufds[2].events = POLLOUT;
    ufds[3].fd = sd2;
    ufds[3].events = POLLOUT;
    ufds[4].fd = sd2;
    ufds[4].events = POLLOUT;
  </code></pre>
  
  <p>And then do what exactly so that messeges can be read in and written out?</p>
