- * $Log: odr_cons.c,v $
- * Revision 1.19 1999-04-20 09:56:48 adam
- * Added 'name' paramter to encoder/decoder routines (typedef Odr_fun).
- * Modified all encoders/decoders to reflect this change.
- *
- * Revision 1.18 1997/05/14 06:53:58 adam
- * C++ support.
- *
- * Revision 1.17 1996/10/23 12:31:24 adam
- * Added 'static' modifier to dummy variable in odr_constructed_begin.
- *
- * Revision 1.16 1996/07/26 13:38:20 quinn
- * Various smaller things. Gathered header-files.
- *
- * Revision 1.15 1995/09/29 17:12:23 quinn
- * Smallish
- *
- * Revision 1.14 1995/09/27 15:02:58 quinn
- * Modified function heads & prototypes.
- *
- * Revision 1.13 1995/08/15 11:16:39 quinn
- * Fixed pretty-printers.
- *
- * Revision 1.12 1995/06/19 12:38:47 quinn
- * Added BER dumper.
- *
- * Revision 1.11 1995/05/16 08:50:53 quinn
- * License, documentation, and memory fixes
- *
- * Revision 1.10 1995/04/18 08:15:21 quinn
- * Added dynamic memory allocation on encoding (whew). Code is now somewhat
- * neater. We'll make the same change for decoding one day.
- *
- * Revision 1.9 1995/03/28 09:15:49 quinn
- * Fixed bug in the printing mode
- *
- * Revision 1.8 1995/03/15 11:18:04 quinn
- * Fixed serious bug in odr_cons
- *
- * Revision 1.7 1995/03/10 11:44:41 quinn
- * Fixed serious stack-bug in odr_cons_begin
- *
- * Revision 1.6 1995/03/08 12:12:23 quinn
- * Added better error checking.
- *
- * Revision 1.5 1995/02/10 18:57:25 quinn
- * More in the way of error-checking.
- *
- * Revision 1.4 1995/02/10 15:55:29 quinn
- * Bug fixes, mostly.
- *
- * Revision 1.3 1995/02/09 15:51:48 quinn
- * Works better now.
- *
- * Revision 1.2 1995/02/07 17:52:59 quinn
- * A damn mess, but now things work, I think.
- *
- * Revision 1.1 1995/02/02 16:21:53 quinn
- * First kick.
