  $Log: tcpEndpoint.h,v $
  Revision 1.1.2.6  2003/05/02 09:58:14  dgrisby
  Ensure shutdown happens even if the TCP stack has broken.

  Revision 1.1.2.5  2002/08/21 06:23:16  dgrisby
  Properly clean up bidir connections and ropes. Other small tweaks.

  Revision 1.1.2.4  2001/07/31 16:16:16  sll
  New transport interface to support the monitoring of active connections.

  Revision 1.1.2.3  2001/07/13 15:34:24  sll
  Added the ability to monitor connections and callback to the giopServer when
  data has arrived at a connection.

  Revision 1.1.2.2  2001/06/20 18:35:15  sll
  Upper case send,recv,connect,shutdown to avoid silly substutition by
  macros defined in socket.h to rename these socket functions
  to something else.

  Revision 1.1.2.1  2001/04/18 18:10:43  sll
  Big checkin with the brand new internal APIs.
