6 * NT server based on threads by
7 * Chas Woodfield, Fretwell Downing Datasystems.
10 * Revision 1.61 2000-03-15 12:59:49 adam
11 * Added handle member to statserv_control.
13 * Revision 1.60 2000/03/14 09:06:11 adam
14 * Added POSIX threads support for frontend server.
16 * Revision 1.59 1999/11/30 13:47:12 adam
17 * Improved installation. Moved header files to include/yaz.
19 * Revision 1.58 1999/08/27 09:40:32 adam
20 * Renamed logf function to yaz_log. Removed VC++ project files.
22 * Revision 1.57 1999/07/06 12:17:15 adam
23 * Added option -1 that runs server once (for profiling purposes).
25 * Revision 1.56 1999/06/10 11:45:30 adam
26 * Added bend_start, bend_stop handlers and removed pre_init.
27 * Handlers bend_start/bend_stop are called when service/daemon is
30 * Revision 1.55 1999/06/10 09:18:54 adam
31 * Modified so that pre_init is called when service/server is started.
33 * Revision 1.54 1999/04/16 14:45:55 adam
34 * Added interface for tcpd wrapper for access control.
36 * Revision 1.53 1999/02/02 13:57:39 adam
37 * Uses preprocessor define WIN32 instead of WINDOWS to build code
38 * for Microsoft WIN32.
40 * Revision 1.52 1998/08/21 14:13:34 adam
41 * Added GNU Configure script to build Makefiles.
43 * Revision 1.51 1998/07/07 15:51:03 adam
44 * Changed server so that it stops if bind fails - "address already in
45 * use" typically causes this.
47 * Revision 1.50 1998/06/22 11:32:39 adam
48 * Added 'conditional cs_listen' feature.
50 * Revision 1.49 1998/02/27 14:04:55 adam
51 * Fixed bug in statserv_remove.
53 * Revision 1.48 1998/02/11 11:53:36 adam
54 * Changed code so that it compiles as C++.
56 * Revision 1.47 1998/02/10 10:28:57 adam
57 * Added app_name, service_dependencies, service_display_name and
58 * options_func. options_func allows us to specify a different function
59 * to interogate the command line arguments. The other members allow us
60 * to pass the full service details accross to the service manager (CW).
63 * Revision 1.46 1998/01/30 15:24:57 adam
64 * Fixed bug in inetd code. The server listened on tcp:@:9999 even
65 * though it was started in inetd mode.
67 * Revision 1.45 1998/01/29 13:30:23 adam
68 * Better event handle system for NT/Unix.
70 * Revision 1.44 1997/11/07 13:31:52 adam
71 * Added NT Service name part of statserv_options_block. Moved NT
72 * service utility to server library.
74 * Revision 1.43 1997/10/31 12:20:09 adam
75 * Improved memory debugging for xmalloc/nmem.c. References to NMEM
76 * instead of ODR in n ESPEC-1 handling in source d1_espec.c.
77 * Bug fix: missing fclose in data1_read_espec1.
79 * Revision 1.42 1997/10/27 14:03:02 adam
80 * Added new member to statserver_options_block, pre_init, which
81 * specifies a callback to be invoked after command line parsing and
82 * before the server listens for the first time.
84 * Revision 1.41 1997/09/29 07:19:32 adam
85 * Server library uses nmem_init/nmem_exit. The log prefix no longer
86 * includes leading path on NT.
88 * Revision 1.40 1997/09/17 12:10:41 adam
91 * Revision 1.39 1997/09/09 10:10:19 adam
92 * Another MSV5.0 port. Changed projects to include proper
93 * library/include paths.
94 * Server starts server in test-mode when no options are given.
96 * Revision 1.38 1997/09/04 14:19:14 adam
99 * Revision 1.37 1997/09/01 08:53:01 adam
100 * New windows NT/95 port using MSV5.0. The test server 'ztest' was
101 * moved a separate directory. MSV5.0 project server.dsp created.
102 * As an option, the server can now operate as an NT service.
104 * Revision 1.36 1996/07/06 19:58:36 quinn
105 * System headerfiles gathered in yconfig
107 * Revision 1.35 1996/05/29 10:03:28 quinn
110 * Revision 1.34 1996/02/21 13:12:07 quinn
111 * *** empty log message ***
113 * Revision 1.33 1996/02/10 12:23:49 quinn
114 * Enable inetd operations fro TCP/IP stack
116 * Revision 1.32 1996/01/19 15:41:52 quinn
117 * *** empty log message ***
119 * Revision 1.31 1995/11/17 11:09:39 adam
120 * Added new option '-c' to specify configuration name in control block.
122 * Revision 1.30 1995/11/01 13:54:59 quinn
