$Log: cPersistence.h,v $
Revision 1.9 1997/12/15 15:55:16 jim
Changed persistent object header layout. This will require recompile
of all C Persistent objects.
Revision 1.8 1997/12/10 22:19:24 jim
Added PER_USE macro.
Revision 1.7 1997/07/18 14:15:39 jim
Added PER_DEL so that subclasses can handle deallocation correctly.
Revision 1.6 1997/06/06 19:13:32 jim
Changed/fixed convenience macros.
Revision 1.5 1997/05/19 17:51:20 jim
Added macros to simplify C PO implementation.
Revision 1.4 1997/05/19 13:49:36 jim
Added include of time.h.
Revision 1.3 1997/04/27 09:18:23 jim
Added to the CAPI to support subtypes (like Record) that want to
extend attr functions.
Revision 1.2 1997/04/22 02:40:28 jim
Changed object header layout.

$Log: cPersistence.h,v $
Revision 1.9 1997/12/15 15:55:16 jim
Changed persistent object header layout. This will require recompile
of all C Persistent objects.
Revision 1.8 1997/12/10 22:19:24 jim
Added PER_USE macro.
Revision 1.7 1997/07/18 14:15:39 jim
Added PER_DEL so that subclasses can handle deallocation correctly.
Revision 1.6 1997/06/06 19:13:32 jim
Changed/fixed convenience macros.
Revision 1.5 1997/05/19 17:51:20 jim
Added macros to simplify C PO implementation.
Revision 1.4 1997/05/19 13:49:36 jim
Added include of time.h.
Revision 1.3 1997/04/27 09:18:23 jim
Added to the CAPI to support subtypes (like Record) that want to
extend attr functions.
Revision 1.2 1997/04/22 02:40:28 jim
Changed object header layout.
Revision 1.1 1997/04/01 17:15:48 jim
