title: pthread and select
body: <p>there.</p>
  
  <p>I am trying to program a server.</p>
  
  <p>The server receive some information from client </p>
  
  <p>and it sends the information to the other server and it receive the response.</p>
  
  <p>Do I need to use select() on this case?</p>
  
  <p>or Pthread only is enough to do this.</p>
  
  <p>my server has many clients connecting concurrently</p>
  
  <p>please answer me kindly.</p>
  
  <p>And if there is, please tell me the source code or site that I can refer to</p>
