Nor will they be automatically restarted when the inets application is restarted, but as long as the inets application is up and running they will be supervised and may be soft code upgraded. Services started as <c>stand_alone</c>, e.i. the service is not started as part of the inets application, will lose all OTP application benefits such as soft upgrade. The "stand_alone-service" will be linked to the process that started it. In most cases some of the supervision functionality will still be in place and in some sense the calling process has now become the top supervisor.</p> </note> <marker id="stop2"></marker> </desc> </func> <func> <name>stop(Service, Reference) -> ok | {error, Reason} </name> <fsummary>Stops a started service of the inets application or takes down a "stand_alone-service" gracefully.</fsummary> <type> <v>Service = service() | stand_alone</v> <v>Reference = pid() | term() - service specified reference</v> <v>Reason = term()</v> </type> <desc> <p>Stops a started service of the inets application or takes down a "stand_alone-service" gracefully.
