  * $Log: lockidx.c,v $
- * Revision 1.3  1995-12-11 11:43:29  adam
+ * Revision 1.8  1997-02-12 20:39:46  adam
+ * Implemented options -f <n> that limits the log to the first <n>
+ * records.
+ * Changed some log messages also.
+ *
+ * Revision 1.7  1996/10/29 14:08:13  adam
+ * Uses resource lockDir instead of lockPath.
+ *
+ * Revision 1.6  1996/03/26 16:01:13  adam
+ * New setting lockPath: directory of various lock files.
+ *
+ * Revision 1.5  1995/12/13  08:46:09  adam
+ * Locking uses F_WRLCK and F_RDLCK again!
+ *
+ * Revision 1.4  1995/12/12  16:00:57  adam
+ * System call sync(2) used after update/commit.
+ * Locking (based on fcntl) uses F_EXLCK and F_SHLCK instead of F_WRLCK
+ * and F_RDLCK.
+ *
+ * Revision 1.3  1995/12/11  11:43:29  adam
  * Locking based on fcntl instead of flock.
  * Setting commitEnable removed. Command line option -n can be used to
  * prevent commit if commit setting is defined in the configuration file.
