type SCMApplet#
SCMApplet is an applet that can run under the Windows Service Control Manager. It extends Applet, so the same applet serves both launch modes: started as a normal process the framework drives Run as usual; under the SCM it drives Execute instead.
In service mode Main calls svc.Run with a framework-owned handler; that handler reports a start-pending status to the SCM immediately — so the service is not killed for slow startup — receives the argument vector in its Execute call, runs the standard pipeline (parse, resolve, configure, start), and only then delegates to the applet's Execute, forwarding the SCM request/status channels so stop, shutdown and interrogate requests reach the applet directly.
When Execute is invoked the service state reported to the SCM is still start-pending: the framework never reports Running — the applet owns that transition and performs it itself (with the accepted-commands mask it wants) once it is ready to serve.
When Execute returns, the framework stops every started service in reverse order and reports the final status to the SCM. The signature mirrors svc.Handler's Execute.
type SCMApplet interface { Applet Execute(args []string, req <-chan svc.ChangeRequest, status chan<- svc.Status) (svcSpecificEC bool, exitCode uint32) }
