6 * NT server based on threads by
7 * Chas Woodfield, Fretwell Downing Informatics.
10 * Revision 1.67 2000-11-23 10:58:32 adam
11 * SSL comstack support. Separate POSIX thread support library.
13 * Revision 1.66 2000/10/06 12:00:28 adam
14 * Fixed Handle leak for WIN32.
16 * Revision 1.65 2000/09/04 08:58:15 adam
17 * Added prefix yaz_ for most logging utility functions.
19 * Revision 1.64 2000/04/05 07:39:55 adam
20 * Added shared library support (libtool).
22 * Revision 1.63 2000/03/20 19:06:25 adam
23 * Added Segment request for fronend server. Work on admin for client.
25 * Revision 1.62 2000/03/17 12:47:02 adam
26 * Minor changes to admin client.
28 * Revision 1.61 2000/03/15 12:59:49 adam
29 * Added handle member to statserv_control.
31 * Revision 1.60 2000/03/14 09:06:11 adam
32 * Added POSIX threads support for frontend server.
34 * Revision 1.59 1999/11/30 13:47:12 adam
35 * Improved installation. Moved header files to include/yaz.
37 * Revision 1.58 1999/08/27 09:40:32 adam
38 * Renamed logf function to yaz_log. Removed VC++ project files.
40 * Revision 1.57 1999/07/06 12:17:15 adam
41 * Added option -1 that runs server once (for profiling purposes).
43 * Revision 1.56 1999/06/10 11:45:30 adam
44 * Added bend_start, bend_stop handlers and removed pre_init.
45 * Handlers bend_start/bend_stop are called when service/daemon is
48 * Revision 1.55 1999/06/10 09:18:54 adam
49 * Modified so that pre_init is called when service/server is started.
51 * Revision 1.54 1999/04/16 14:45:55 adam
52 * Added interface for tcpd wrapper for access control.
54 * Revision 1.53 1999/02/02 13:57:39 adam
55 * Uses preprocessor define WIN32 instead of WINDOWS to build code
56 * for Microsoft WIN32.
58 * Revision 1.52 1998/08/21 14:13:34 adam
59 * Added GNU Configure script to build Makefiles.
61 * Revision 1.51 1998/07/07 15:51:03 adam
62 * Changed server so that it stops if bind fails - "address already in
63 * use" typically causes this.
65 * Revision 1.50 1998/06/22 11:32:39 adam
66 * Added 'conditional cs_listen' feature.
68 * Revision 1.49 1998/02/27 14:04:55 adam

71 * Revision 1.48 1998/02/11 11:53:36 adam
72 * Changed code so that it compiles as C++.
74 * Revision 1.47 1998/02/10 10:28:57 adam
75 * Added app_name, service_dependencies, service_display_name and
76 * options_func. options_func allows us to specify a different function
77 * to interogate the command line arguments. The other members allow us
78 * to pass the full service details accross to the service manager (CW).
81 * Revision 1.46 1998/01/30 15:24:57 adam
82 * Fixed bug in inetd code. The server listened on tcp:@:9999 even
83 * though it was started in inetd mode.
85 * Revision 1.45 1998/01/29 13:30:23 adam
86 * Better event handle system for NT/Unix.
88 * Revision 1.44 1997/11/07 13:31:52 adam
89 * Added NT Service name part of statserv_options_block. Moved NT
90 * service utility to server library.
92 * Revision 1.43 1997/10/31 12:20:09 adam
93 * Improved memory debugging for xmalloc/nmem.c. References to NMEM
94 * instead of ODR in n ESPEC-1 handling in source d1_espec.c.
95 * Bug fix: missing fclose in data1_read_espec1.
97 * Revision 1.42 1997/10/27 14:03:02 adam
98 * Added new member to statserver_options_block, pre_init, which
99 * specifies a callback to be invoked after command line parsing and
100 * before the server listens for the first time.
102 * Revision 1.41 1997/09/29 07:19:32 adam
103 * Server library uses nmem_init/nmem_exit. The log prefix no longer
104 * includes leading path on NT.
106 * Revision 1.40 1997/09/17 12:10:41 adam
109 * Revision 1.39 1997/09/09 10:10:19 adam
110 * Another MSV5.0 port. Changed projects to include proper
111 * library/include paths.
112 * Server starts server in test-mode when no options are given.
114 * Revision 1.38 1997/09/04 14:19:14 adam
117 * Revision 1.37 1997/09/01 08:53:01 adam
118 * New windows NT/95 port using MSV5.0. The test server 'ztest' was
119 * moved a separate directory. MSV5.0 project server.dsp created.
120 * As an option, the server can now operate as an NT service.
122 * Revision 1.36 1996/07/06 19:58:36 quinn
123 * System headerfiles gathered in yconfig
125 * Revision 1.35 1996/05/29 10:03:28 quinn
128 * Revision 1.34 1996/02/21 13:12:07 quinn
129 * *** empty log message ***
