6 * NT server based on threads by
7 * Chas Woodfield, Fretwell Downing Informatics.
10 * Revision 1.72 2001-03-25 21:55:13 adam
11 * Added odr_intdup. Ztest server returns TaskPackage for ItemUpdate.
13 * Revision 1.71 2001/03/21 12:43:36 adam
14 * Implemented cs_create_host. Better error reporting for SSL comstack.
16 * Revision 1.70 2001/02/01 08:52:26 adam
17 * Fixed bug regarding inetd mode.
19 * Revision 1.69 2000/12/01 17:56:41 adam
20 * on WIN32 function statserv_closedown closes socket(s) to provoke close.
22 * Revision 1.68 2000/11/29 14:22:47 adam
23 * Implemented XML/SGML attributes for data1 so that d1_read reads them
24 * and d1_write generates proper attributes for XML/SGML records. Added
25 * register locking for threaded version.
27 * Revision 1.67 2000/11/23 10:58:32 adam
28 * SSL comstack support. Separate POSIX thread support library.

33 * Revision 1.65 2000/09/04 08:58:15 adam
34 * Added prefix yaz_ for most logging utility functions.
36 * Revision 1.64 2000/04/05 07:39:55 adam
37 * Added shared library support (libtool).
39 * Revision 1.63 2000/03/20 19:06:25 adam
40 * Added Segment request for fronend server. Work on admin for client.
42 * Revision 1.62 2000/03/17 12:47:02 adam
43 * Minor changes to admin client.
45 * Revision 1.61 2000/03/15 12:59:49 adam
46 * Added handle member to statserv_control.
48 * Revision 1.60 2000/03/14 09:06:11 adam
49 * Added POSIX threads support for frontend server.
51 * Revision 1.59 1999/11/30 13:47:12 adam
52 * Improved installation. Moved header files to include/yaz.
54 * Revision 1.58 1999/08/27 09:40:32 adam
55 * Renamed logf function to yaz_log. Removed VC++ project files.
57 * Revision 1.57 1999/07/06 12:17:15 adam
58 * Added option -1 that runs server once (for profiling purposes).
60 * Revision 1.56 1999/06/10 11:45:30 adam
61 * Added bend_start, bend_stop handlers and removed pre_init.
62 * Handlers bend_start/bend_stop are called when service/daemon is
65 * Revision 1.55 1999/06/10 09:18:54 adam
66 * Modified so that pre_init is called when service/server is started.
68 * Revision 1.54 1999/04/16 14:45:55 adam
69 * Added interface for tcpd wrapper for access control.
71 * Revision 1.53 1999/02/02 13:57:39 adam
72 * Uses preprocessor define WIN32 instead of WINDOWS to build code
73 * for Microsoft WIN32.
75 * Revision 1.52 1998/08/21 14:13:34 adam
76 * Added GNU Configure script to build Makefiles.
78 * Revision 1.51 1998/07/07 15:51:03 adam
79 * Changed server so that it stops if bind fails - "address already in
80 * use" typically causes this.
82 * Revision 1.50 1998/06/22 11:32:39 adam
83 * Added 'conditional cs_listen' feature.
85 * Revision 1.49 1998/02/27 14:04:55 adam

91 * Revision 1.47 1998/02/10 10:28:57 adam
92 * Added app_name, service_dependencies, service_display_name and
93 * options_func. options_func allows us to specify a different function
94 * to interogate the command line arguments. The other members allow us
95 * to pass the full service details accross to the service manager (CW).
98 * Revision 1.46 1998/01/30 15:24:57 adam
99 * Fixed bug in inetd code. The server listened on tcp:@:9999 even
100 * though it was started in inetd mode.
102 * Revision 1.45 1998/01/29 13:30:23 adam
103 * Better event handle system for NT/Unix.
105 * Revision 1.44 1997/11/07 13:31:52 adam

107 * service utility to server library.
109 * Revision 1.43 1997/10/31 12:20:09 adam
110 * Improved memory debugging for xmalloc/nmem.c. References to NMEM
111 * instead of ODR in n ESPEC-1 handling in source d1_espec.c.
112 * Bug fix: missing fclose in data1_read_espec1.
114 * Revision 1.42 1997/10/27 14:03:02 adam
115 * Added new member to statserver_options_block, pre_init, which
116 * specifies a callback to be invoked after command line parsing and
117 * before the server listens for the first time.
119 * Revision 1.41 1997/09/29 07:19:32 adam
120 * Server library uses nmem_init/nmem_exit. The log prefix no longer
121 * includes leading path on NT.
123 * Revision 1.40 1997/09/17 12:10:41 adam
126 * Revision 1.39 1997/09/09 10:10:19 adam
127 * Another MSV5.0 port. Changed projects to include proper
128 * library/include paths.
129 * Server starts server in test-mode when no options are given.
131 * Revision 1.38 1997/09/04 14:19:14 adam
134 * Revision 1.37 1997/09/01 08:53:01 adam
135 * New windows NT/95 port using MSV5.0. The test server 'ztest' was
136 * moved a separate directory. MSV5.0 project server.dsp created.
137 * As an option, the server can now operate as an NT service.
139 * Revision 1.36 1996/07/06 19:58:36 quinn
140 * System headerfiles gathered in yconfig
142 * Revision 1.35 1996/05/29 10:03:28 quinn
