90 * Revision 1.51 1998/07/07 15:51:03 adam
91 * Changed server so that it stops if bind fails - "address already in
92 * use" typically causes this.
94 * Revision 1.50 1998/06/22 11:32:39 adam

104 * Added app_name, service_dependencies, service_display_name and
105 * options_func. options_func allows us to specify a different function
106 * to interogate the command line arguments. The other members allow us
107 * to pass the full service details accross to the service manager (CW).
110 * Revision 1.46 1998/01/30 15:24:57 adam
111 * Fixed bug in inetd code. The server listened on tcp:@:9999 even
112 * though it was started in inetd mode.
114 * Revision 1.45 1998/01/29 13:30:23 adam
115 * Better event handle system for NT/Unix.

119 * service utility to server library.
121 * Revision 1.43 1997/10/31 12:20:09 adam
122 * Improved memory debugging for xmalloc/nmem.c. References to NMEM
123 * instead of ODR in n ESPEC-1 handling in source d1_espec.c.
124 * Bug fix: missing fclose in data1_read_espec1.
126 * Revision 1.42 1997/10/27 14:03:02 adam
127 * Added new member to statserver_options_block, pre_init, which
128 * specifies a callback to be invoked after command line parsing and
129 * before the server listens for the first time.
131 * Revision 1.41 1997/09/29 07:19:32 adam
132 * Server library uses nmem_init/nmem_exit. The log prefix no longer
133 * includes leading path on NT.
135 * Revision 1.40 1997/09/17 12:10:41 adam
138 * Revision 1.39 1997/09/09 10:10:19 adam
139 * Another MSV5.0 port. Changed projects to include proper
140 * library/include paths.
141 * Server starts server in test-mode when no options are given.
143 * Revision 1.38 1997/09/04 14:19:14 adam
146 * Revision 1.37 1997/09/01 08:53:01 adam

148 * moved a separate directory. MSV5.0 project server.dsp created.
149 * As an option, the server can now operate as an NT service.
151 * Revision 1.36 1996/07/06 19:58:36 quinn
