* $Log: statserv.c,v $
- * Revision 1.37 1997-09-01 08:53:01 adam
+ * Revision 1.59 1999-11-30 13:47:12 adam
+ * Improved installation. Moved header files to include/yaz.
+ *
+ * Revision 1.58 1999/08/27 09:40:32 adam
+ * Renamed logf function to yaz_log. Removed VC++ project files.
+ *
+ * Revision 1.57 1999/07/06 12:17:15 adam
+ * Added option -1 that runs server once (for profiling purposes).
+ *
+ * Revision 1.56 1999/06/10 11:45:30 adam
+ * Added bend_start, bend_stop handlers and removed pre_init.
+ * Handlers bend_start/bend_stop are called when service/daemon is
+ * started/stopped.
+ *
+ * Revision 1.55 1999/06/10 09:18:54 adam
+ * Modified so that pre_init is called when service/server is started.
+ *
+ * Revision 1.54 1999/04/16 14:45:55 adam
+ * Added interface for tcpd wrapper for access control.
+ *
+ * Revision 1.53 1999/02/02 13:57:39 adam
+ * Uses preprocessor define WIN32 instead of WINDOWS to build code
+ * for Microsoft WIN32.
+ *
+ * Revision 1.52 1998/08/21 14:13:34 adam
+ * Added GNU Configure script to build Makefiles.
+ *
+ * Revision 1.51 1998/07/07 15:51:03 adam
+ * Changed server so that it stops if bind fails - "address already in
+ * use" typically causes this.
+ *
+ * Revision 1.50 1998/06/22 11:32:39 adam
+ * Added 'conditional cs_listen' feature.
+ *
+ * Revision 1.49 1998/02/27 14:04:55 adam
+ * Fixed bug in statserv_remove.
+ *
+ * Revision 1.48 1998/02/11 11:53:36 adam
+ * Changed code so that it compiles as C++.
+ *
+ * Revision 1.47 1998/02/10 10:28:57 adam
+ * Added app_name, service_dependencies, service_display_name and
+ * options_func. options_func allows us to specify a different function
+ * to interogate the command line arguments. The other members allow us
+ * to pass the full service details accross to the service manager (CW).
+ *
+ *
+ * Revision 1.46 1998/01/30 15:24:57 adam
+ * Fixed bug in inetd code. The server listened on tcp:@:9999 even
+ * though it was started in inetd mode.
+ *
+ * Revision 1.45 1998/01/29 13:30:23 adam
+ * Better event handle system for NT/Unix.
+ *
+ * Revision 1.44 1997/11/07 13:31:52 adam
+ * Added NT Service name part of statserv_options_block. Moved NT
+ * service utility to server library.
+ *
+ * Revision 1.43 1997/10/31 12:20:09 adam
+ * Improved memory debugging for xmalloc/nmem.c. References to NMEM
+ * instead of ODR in n ESPEC-1 handling in source d1_espec.c.
+ * Bug fix: missing fclose in data1_read_espec1.
+ *
+ * Revision 1.42 1997/10/27 14:03:02 adam
+ * Added new member to statserver_options_block, pre_init, which
+ * specifies a callback to be invoked after command line parsing and
+ * before the server listens for the first time.
+ *
+ * Revision 1.41 1997/09/29 07:19:32 adam
+ * Server library uses nmem_init/nmem_exit. The log prefix no longer
+ * includes leading path on NT.
+ *
+ * Revision 1.40 1997/09/17 12:10:41 adam
+ * YAZ version 1.4.
+ *
+ * Revision 1.39 1997/09/09 10:10:19 adam
+ * Another MSV5.0 port. Changed projects to include proper
+ * library/include paths.
+ * Server starts server in test-mode when no options are given.
+ *
+ * Revision 1.38 1997/09/04 14:19:14 adam
+ * Added credits.
+ *
+ * Revision 1.37 1997/09/01 08:53:01 adam
* New windows NT/95 port using MSV5.0. The test server 'ztest' was
* moved a separate directory. MSV5.0 project server.dsp created.
* As an option, the server can now operate as an NT service.
