NSSM: The Non-Sucking Service Manager\r
-Version 2.15, 2012-07-19\r
+Version 2.16, 2012-12-01\r
\r
NSSM is a service helper program similar to srvany and cygrunsrv. It can \r
start any application as an NT service and will restart the service if it \r
Since version 2.15, NSSM is translated into Italian.\r
Thanks Riccardo Gusmeroli.\r
\r
+Since version 2.17, NSSM can try to shut down console applications by\r
+simulating a Control-C keypress. If they have installed a handler routine\r
+they can clean up and shut down gracefully on receipt of the event.\r
+\r
+Since version 2.17, NSSM can redirect the managed application's I/O streams\r
+to an arbitrary path.\r

Usage\r
-----\r
In the usage notes below, arguments to the program may be written in angle \r
\r
Don't forget to enclose paths in "quotes" if they contain spaces!\r
\r
+If you want to include quotes in the options you will need to """quote""" the\r
+quotes.\r

\r
Managing the service\r
--------------------\r
If only the default action is set to Suicide NSSM will instead exit gracefully.\r
\r
\r
+Stopping the service\r
+--------------------\r
+When stopping a service NSSM will attempt several different methods of killing\r
+the monitored application, each of which can be disabled if necessary.\r
+\r
+First NSSM will attempt to generate a Control-C event and send it to the\r
+application's console. Batch scripts or console applications may intercept\r
+the event and shut themselves down gracefully. GUI applications do not have\r
+consoles and will not respond to this method.\r
+\r
+Secondly NSSM will enumerate all windows created by the application and send\r
+them a WM_CLOSE message, requesting a graceful exit.\r
+\r
+Thirdly NSSM will enumerate all threads created by the application and send\r
+them a WM_QUIT message, requesting a graceful exit. Not all applications'\r
+threads have message queues; those which do not will not respond to this\r
+method.\r
+\r
+Finally NSSM will call TerminateProcess() to request that the operating\r
+system forcibly terminate the application. TerminateProcess() cannot be\r
+trapped or ignored, so in most circumstances the application will be killed.\r
+However, there is no guarantee that it will have a chance to perform any\r
+tidyup operations before it exits.\r
+\r
+Any or all of the methods above may be disabled. NSSM will look for the\r
+HKLM\SYSTEM\CurrentControlSet\Services\<service>\Parameters\AppStopMethodSkip\r
+registry value which should be of type REG_DWORD set to a bit field describing\r
+which methods should not be applied.\r
+\r
+ If AppStopMethodSkip includes 1, Control-C events will not be generated.\r
+ If AppStopMethodSkip includes 2, WM_CLOSE messages will not be posted.\r
+ If AppStopMethodSkip includes 4, WM_QUIT messages will not be posted.\r
+ If AppStopMethodSkip includes 8, TerminateProcess() will not be called.\r
+\r
+If, for example, you knew that an application did not respond to Control-C\r
+events and did not have a thread message queue, you could set AppStopMethodSkip\r
+to 5 and NSSM would not attempt to use those methods to stop the application.\r
+\r
+Take great care when including 8 in the value of AppStopMethodSkip. If NSSM\r
+does not call TerminateProcess() it is possible that the application will not\r
+exit when the service stops.\r
+\r
+\r
+I/O redirection\r
+---------------\r
+NSSM can redirect the managed application's I/O to any path capable of being\r
+opened by CreateFile(). This enables, for example, capturing the log output\r
+of an application which would otherwise only write to the console or accepting\r
+input from a serial port.\r
+\r
+NSSM will look in the registry under\r
+HKLM\SYSTEM\CurrentControlSet\Services\<service>\Parameters for the keys\r
+corresponding to arguments to CreateFile(). All are optional. If no path is\r
+given for a particular stream it will not be redirected. If a path is given\r
+but any of the other values are omitted they will be receive sensible defaults.\r
+\r
+ AppStdin: Path to receive input.\r
+ AppStdout: Path to receive output.\r
+ AppStderr: Path to receive error output.\r
+\r
+Parameters for CreateFile() are providing with the "AppStdinShareMode",\r
+"AppStdinCreationDisposition" and "AppStdinFlagsAndAttributes" values (and\r
+analogously for stdout and stderr).\r
+\r
+In general, if you want the service to log its output, set AppStdout and\r
+AppStderr to the same path, eg C:\Users\Public\service.log, and it should\r
+work. Remember, however, that the path must be accessible to the user\r
+running the service.\r
+\r
+\r
Removing services using the GUI\r
-------------------------------\r
NSSM can also remove services. Run\r
Thanks to Emilio Frini for spotting that French was inadvertently set as\r
the default language when the user's display language was not translated.\r
Thanks to Riccardo Gusmeroli for Italian translation.\r
+Thanks to Eric Cheldelin for the inspiration to generate a Control-C event\r
+on shutdown.\r
+Thanks to Brian Baxter for suggesting how to escape quotes from the command prompt.\r
