- * Revision 1.41 2000-01-10 15:16:53 adam
+ * Revision 1.48 2001-09-27 12:09:18 adam
+ * Function nmem_exit calls oid_exit (when reference is 0).
+ *
+ * Revision 1.47 2001/09/24 21:51:55 adam
+ * New Z39.50 OID utilities: yaz_oidval_to_z3950oid, yaz_str_to_z3950oid
+ * and yaz_z3950oid_to_str.
+ *
+ * Revision 1.46 2001/06/26 14:11:27 adam
+ * Added MUTEX functions for NMEM module (used by OID utility).
+ *
+ * Revision 1.45 2001/05/16 07:25:59 adam
+ * Modified oid_ent_to_oid so that if proto is general, then class
+ * is ignored (only oid value is compared).
+ *
+ * Revision 1.44 2000/10/02 13:58:50 adam
+ * Added some OID's.
+ *
+ * Revision 1.43 2000/03/14 09:21:08 ian
+ * Added Admin Extended Service OID
+ *
+ * Revision 1.42 2000/02/29 13:44:55 adam
+ * Check for config.h (currently not generated).
+ *
+ * Revision 1.41 2000/01/10 15:16:53 adam
* Added several OID's.
*
* Revision 1.40 2000/01/06 14:59:13 adam
* We could (and should?) extend this so that the user app can add new
* entries to the list at initialization.
