Finally, we can do something useful
with the service. The simplest thing is to query the current status
of the service.
>>> status=win32service.QueryServiceStatus(hs) >>> status (32, 4, 5, 0, 0, 0, 0) >>>
So what does this say? A quick check of Appendix B gives the data returned for a service status, but briefly, the information includes:
The type of service.
The current state of the service, i.e., is it running, stopped, stopping, etc.
The type of controls the service accepts, i.e., can it be stopped, paused, etc.
A Win32 error code, as set by the service. This is typically set once the service stops.
A service-specific error code. This is typically set once the service stops.
The service’s checkpoint. See Appendix B for details.
The service’s wait-hint. See Appendix B for details.
Armed with this information, you can create a function to print a description of the service status:
>>> def PrintServiceStatus(status): ... svcType, svcState, svcControls, err, svcErr, svcCP, svcWH = status ... if svcType & win32service.SERVICE_WIN32_OWN_PROCESS: ... print "The service runs in its own process" ... if svcType & win32service.SERVICE_WIN32_SHARE_PROCESS: ... print "The service shares a process with other services" ... if svcType & win32service.SERVICE_INTERACTIVE_PROCESS: ... print "The service can interact with the desktop" ... # Other svcType flags not shown. ... if svcState==win32service.SERVICE_STOPPED: ... print ...
