9  MODULE: service.h
10 
11  Comments:  The use of this header file and the accompanying service.c
12  file simplifies the process of writting a service.  You as a developer
13  simply need to follow the TODO's outlined in this header file, and
14  implement the ServiceStart() and ServiceStop() functions.
15 
16  There is no need to modify the code in service.c.  Just add service.c
17  to your project and link with the following libraries...
18 
19  libcmt.lib kernel32.lib advapi.lib shell32.lib
20 
21  This code also supports unicode.  Be sure to compile both service.c and
22  and code #include "service.h" with the same Unicode setting.
23 
24  Upon completion, your code will have the following command line interface
25 
26  <service exe> -?                to display this list
27  <service exe> -install          to install the service
28  <service exe> -remove           to remove the service
29  <service exe> -debug <params>   to run as a console app for debugging
30 
31  Note: This code also implements Ctrl+C and Ctrl+Break handlers
32        when using the debug option.  These console events cause
33        your ServiceStop routine to be called
34 
35        Also, this code only handles the OWN_SERVICE service type
36        running in the LOCAL_SYSTEM security context.
37 
38        To control your service ( start, stop, etc ) you may use the
39        Services control panel applet or the NET.EXE program.
40 
41        To aid in writing/debugging service, the
42        SDK contains a utility (MSTOOLS\BIN\SC.EXE) that
43        can be used to control, configure, or obtain service status.
44        SC displays complete status for any service/driver
45        in the service database, and allows any of the configuration
46        parameters to be easily changed at the command line.
47        For more information on SC.EXE, type SC at the command line.
