SCTP Notification

Hi,

    I am using SCTP(libsctp) in linux 2.6.9. I have subscribed for
Notifications. However, i am not getting any notification when sctp
association is established or peer is shutdown. Is there any correction in
my method of subscription? setsockopt system call is returning success. i
used getsockopt to verify the same.

      struct sockaddr_in stSrcIPAddress;
      socklen_t  Addlen=sizeof(sockaddr_in);
      int  iFlags=-1,iRet=-1;

      struct sctp_sndrcvinfo sndrcvinfo;
      struct sctp_event_subscribe events;

  memset( (void *)&events, 0, sizeof(events) );
  events.sctp_data_io_event = 1;
  events.sctp_association_event = 1;
  events.sctp_send_failure_event = 1;
  events.sctp_shutdown_event = 1;
  events.sctp_peer_error_event = 1;

  ret = setsockopt( iconnSock, IPPROTO_SCTP, SCTP_EVENTS,(const void
*)&events, sizeof(events) );
  while(1)
  {
    iRet = sctp_recvmsg(iconnSock, (void *)pacbuffer,600, (struct sockaddr
*)&stSrcIPAddress, &Addlen, &sndrcvinfo, &iFlags );
    if ( iRet < 0)
    {
    }
    if(iFlags & MSG_NOTIFICATION )//Notification/event is received.
    {
    }
    if (iRet> 0)
    {
    }
}

with regards,
   senthil
