27 * Revision 1.6 2001-06-26 14:11:27 adam
28 * Added MUTEX functions for NMEM module (used by OID utility).
30 * Revision 1.5 2001/03/25 21:55:12 adam
31 * Added odr_intdup. Ztest server returns TaskPackage for ItemUpdate.
33 * Revision 1.4 2000/05/09 11:48:58 adam
34 * Fix (bug introduced by previous commit).
36 * Revision 1.3 2000/05/09 10:55:05 adam
37 * Public nmem_print_list (for debugging).
39 * Revision 1.2 2000/02/28 11:20:06 adam
40 * Using autoconf. New definitions: YAZ_BEGIN_CDECL/YAZ_END_CDECL.
42 * Revision 1.1 1999/11/30 13:47:11 adam
43 * Improved installation. Moved header files to include/yaz.
45 * Revision 1.10 1998/10/19 15:24:20 adam
46 * New nmem utility, nmem_transfer, that transfer blocks from one
49 * Revision 1.9 1998/10/13 16:00:17 adam
50 * Implemented nmem_critical_{enter,leave}.
52 * Revision 1.8 1998/07/20 12:35:59 adam
53 * Added more memory diagnostics (when NMEM_DEBUG is 1).
55 * Revision 1.7 1997/10/31 12:20:08 adam
56 * Improved memory debugging for xmalloc/nmem.c. References to NMEM
57 * instead of ODR in n ESPEC-1 handling in source d1_espec.c.
58 * Bug fix: missing fclose in data1_read_espec1.
