    need technical help regarding multicasting

    Hi Gurus,
    This is my first thread here.

    I m developing p2p multicasting subtrate which is intended to multicast a query string and wait for a response from its groups nodes.

    here i need to wait for some time (eg 5 seconds ) for a response after i multicast the message and print the response. how can i implement this? i know this is simple but as im new to C i hv no idea how to do this.

    here is my code fragment
      // some code here
                  new_mcast_recieve( host ,port );
                  // todo here how can i wait for 5 seconds for a response. if not exit from the loop
       mcast_send(mc , query , sizeof(query));      
      //.some code here
    if you hv a better structure about how to implemet this please sugest me.

    thanks you.
