  //     This class manages the QoS sessions associated with ACE_SOCK.
  //
  // = DESCRIPTION 
  //     This class provides functions to manage the QoS
  //     associated with a socket.  The idea is to keep the management of
  //     QoS for a socket separate from the socket itself. Currently, the
  //     manager is used to manage the QoS session set. It will handle more
  //     responsibilities in the future.

  int join_qos_session (ACE_QoS_Session *qos_session);
  // Join the given QoS session. A socket can join multiple QoS
  // sessions.  This call adds the given QoS session to the list of
  // QoS sessions that the socket has already joined.
