4 * Sebastian Hammer, Adam Dickmeiss
7 * Revision 1.17 1999-10-21 12:06:29 adam
8 * Retrieval module no longer uses ctype.h - functions.
10 * Revision 1.16 1999/08/27 09:40:32 adam
11 * Renamed logf function to yaz_log. Removed VC++ project files.
13 * Revision 1.15 1998/10/13 16:09:49 adam
14 * Added support for arbitrary OID's for tagsets, schemas and attribute sets.
15 * Added support for multiple attribute set references and tagset references
16 * from an abstract syntax file.
17 * Fixed many bad logs-calls in routines that read the various
18 * specifications regarding data1 (*.abs,*.att,...) and made the messages
19 * consistent whenever possible.
20 * Added extra 'lineno' argument to function readconf_line.
22 * Revision 1.14 1998/02/11 11:53:35 adam
23 * Changed code so that it compiles as C++.
25 * Revision 1.13 1997/11/24 11:33:56 adam
26 * Using function odr_nullval() instead of global ODR_NULLVAL when
29 * Revision 1.12 1997/10/31 12:20:09 adam
30 * Improved memory debugging for xmalloc/nmem.c. References to NMEM
31 * instead of ODR in n ESPEC-1 handling in source d1_espec.c.
32 * Bug fix: missing fclose in data1_read_espec1.
34 * Revision 1.11 1997/09/29 13:18:59 adam
35 * Added function, oid_ent_to_oid, to replace the function
36 * oid_getoidbyent, which is not thread safe.
38 * Revision 1.10 1997/09/29 07:21:10 adam
39 * Added typecast to avoid warnings on MSVC.
41 * Revision 1.9 1997/09/17 12:10:35 adam
44 * Revision 1.8 1997/09/05 09:50:56 adam
45 * Removed global data1_tabpath - uses data1_get_tabpath() instead.
47 * Revision 1.7 1997/05/14 06:54:02 adam
50 * Revision 1.6 1996/07/06 19:58:34 quinn
51 * System headerfiles gathered in yconfig
53 * Revision 1.5 1996/01/02 08:57:44 quinn
54 * Changed enums in the ASN.1 .h files to #defines. Changed oident.class to oclass
56 * Revision 1.4 1995/12/05 11:16:10 quinn
59 * Revision 1.3 1995/11/13 09:27:34 quinn
60 * Fiddling with the variant stuff.
62 * Revision 1.2 1995/11/01 16:34:56 quinn
63 * Making data1 look for tables in data1_tabpath
65 * Revision 1.1 1995/11/01 11:56:07 quinn
66 * Added Retrieval (data management) functions en masse.
