+/*++
+/* NAME
+/* master_service 3
+/* SUMMARY
+/* Postfix master - start/stop services
+/* SYNOPSIS
+/* #include "master.h"
+/*
+/* void master_start_service(serv)
+/* MASTER_SERV *serv;
+/*
+/* void master_stop_service(serv)
+/* MASTER_SERV *serv;
+/*
+/* void master_restart_service(serv, conf_reload)
+/* MASTER_SERV *serv;
+/* int conf_reload;
+/* DESCRIPTION
+/* master_start_service() enables the named service.
+/*
+/* master_stop_service() disables named service.
+/*
+/* master_restart_service() requests all running child processes to
+/* commit suicide. The conf_reload argument is either DO_CONF_RELOAD
+/* (configuration files were reloaded, re-evaluate the child process
+/* creation policy) or NO_CONF_RELOAD.
+/* DIAGNOSTICS
+/* BUGS
+/* SEE ALSO
+/* master_avail(3), process creation policy
+/* master_wakeup(3), service automatic wakeup
+/* master_status(3), child status reports
