  New transport interface to support the monitoring of active connections.

  Revision 1.1.2.5  2001/07/13 15:33:28  sll
  Revised declaration to match the changes in giopConnection.

  Revision 1.1.2.4  2001/06/20 18:35:16  sll
  Upper case send,recv,connect,shutdown to avoid silly substutition by
  macros defined in socket.h to rename these socket functions
