How can I drop a UDP (SOCK_DGRAM) packet if it is taken too long to return (from an echo server)? Also, I need it to be reported as lost.

Here's the socket code I can give:

 1  if ( sendto( dsock,                // local socket

 2                      buffer, msglen,       // message
 3                             0,         // Flags
 4                      ( sockaddr * ) &saddr, // destination address

 5                      sizeof(saddr)         // length of destination address
 6                    )
 7                 < msglen ) {

 8             errorExit( "Error sending to server" );
 9         } else {

10             sendCount++; //supposed to count sent packets
11         }
12 
13            msglen = recvfrom( dsock,          // local socket

14                            buffer, buflen, // message buffer, length
15                            0,              // flags
16                            NULL, 0         // sockaddr, length

17                          );
18         if ( msglen < 0 && errno != EAGAIN ) {

19             errorExit( " Failed to recv from data socket" );
20         } else {

21             recvCount++;  //supposed to count received packets
22         }


the counters don't seem to be working (all of this is in a while loop.) I'm using a linux machine. I want to drop any packets that don't match the ones sent by the client (and report that they were dropped).
