title: UDP - Read data from the queue in chunks
body: <p>I'm implementing a small application using UDP (in C). A server sends to a client the data from a given file in chunks of given amount (ex. 100 bytes / call). The client downloads the file and saves it somewhere. The catch is that the client can receive a parameter saying how many bytes to read / call.<br>
  My problem is when the server sends 100 bytes / call, and the client is set to read only 15 bytes / call. The other 85 bytes are lost, because the message is removed from the UDP queue. </p>
  
  <p>Is there a way to read these messages in chunks without removing them from the queue until they're completely read?</p>
