6 * Revision 1.21 2000-01-31 13:15:21 adam
7 * Removed uses of assert(3). Cleanup of ODR. CCL parser update so
8 * that some characters are not surrounded by spaces in resulting term.
11 * Revision 1.20 1999/11/30 13:47:11 adam
12 * Improved installation. Moved header files to include/yaz.
14 * Revision 1.19 1999/04/20 09:56:48 adam
15 * Added 'name' paramter to encoder/decoder routines (typedef Odr_fun).
16 * Modified all encoders/decoders to reflect this change.
18 * Revision 1.18 1997/05/14 06:53:58 adam
21 * Revision 1.17 1996/10/23 12:31:24 adam
22 * Added 'static' modifier to dummy variable in odr_constructed_begin.
24 * Revision 1.16 1996/07/26 13:38:20 quinn
25 * Various smaller things. Gathered header-files.
27 * Revision 1.15 1995/09/29 17:12:23 quinn
30 * Revision 1.14 1995/09/27 15:02:58 quinn
31 * Modified function heads & prototypes.
33 * Revision 1.13 1995/08/15 11:16:39 quinn
34 * Fixed pretty-printers.
36 * Revision 1.12 1995/06/19 12:38:47 quinn
39 * Revision 1.11 1995/05/16 08:50:53 quinn
40 * License, documentation, and memory fixes
42 * Revision 1.10 1995/04/18 08:15:21 quinn
43 * Added dynamic memory allocation on encoding (whew). Code is now somewhat
44 * neater. We'll make the same change for decoding one day.
46 * Revision 1.9 1995/03/28 09:15:49 quinn
47 * Fixed bug in the printing mode
49 * Revision 1.8 1995/03/15 11:18:04 quinn
50 * Fixed serious bug in odr_cons
52 * Revision 1.7 1995/03/10 11:44:41 quinn
53 * Fixed serious stack-bug in odr_cons_begin
55 * Revision 1.6 1995/03/08 12:12:23 quinn
56 * Added better error checking.
58 * Revision 1.5 1995/02/10 18:57:25 quinn
59 * More in the way of error-checking.
61 * Revision 1.4 1995/02/10 15:55:29 quinn
