Microsoft Corporation. All rights reserved. - - MODULE: service.h - - Comments: The use of this header file and the accompanying service.c - file simplifies the process of writting a service. You as a developer - simply need to follow the TODO's outlined in this header file, and - implement the ServiceStart() and ServiceStop() functions. - - There is no need to modify the code in service.c. Just add service.c - to your project and link with the following libraries... - - libcmt.lib kernel32.lib advapi.lib shell32.lib - - This code also supports unicode. Be sure to compile both service.c and - and code #include "service.h" with the same Unicode setting. - - Upon completion, your code will have the following command line interface - - <service exe> -? to display this list - <service exe> -install to install the service - <service exe> -remove to remove the service - <service exe> -debug <params> to run as a console app for debugging - - Note: This code also implements Ctrl+C and Ctrl+Break handlers - when using the debug option. These console events cause - your ServiceStop routine to be called - - Also, this code only handles the OWN_SERVICE service type - running in the LOCAL_SYSTEM security context. - - To control your service ( start, stop, etc ) you may use the - Services control panel applet or the NET.EXE program. - - To aid in writing/debugging service, the - SDK contains a utility (MSTOOLS\BIN\SC.EXE) that - can be used to control, configure, or obtain service status. - SC displays complete status for any service/driver - in the service database, and allows any of the configuration - parameters to be easily changed at the command line. - For more information on SC.EXE, type SC at the command line. - - -------------------------------------------------------------------------------*/ +/* + * OpenVPN -- An application to securely tunnel IP networks + * over a single TCP/UDP port, with support for SSL/TLS-based + * session authentication and key exchange, + * packet encryption, packet authentication, and + * packet compression. + * + * Copyright (C) 2013 Heiko Hund <heiko.hund@sophos.com> + * + * This program is free software; you can redistribute it and/or modify + * it under the terms of the GNU General Public License version 2 + * as published by the Free Software Foundation. + * + * This program is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
