+ * Low-level function to start a service if the scheduler
+ * is already running. Should only be used directly in
+ * special cases.
+ *
+ * The function will launch the service with the name @a service_name
+ * using the @a service_options to configure its shutdown
+ * behavior. When clients connect or disconnect, the respective
+ * @a connect_cb or @a disconnect_cb functions will be called. For
+ * messages received from the clients, the respective @a handlers will
+ * be invoked; for the closure of the handlers we use the return value
+ * from the @a connect_cb invocation of the respective client.
+ *
+ * Each handler MUST call #GNUNET_SERVICE_client_continue() after each
+ * message to receive further messages from this client. If
+ * #GNUNET_SERVICE_client_continue() is not called within a short
+ * time, a warning will be logged. If delays are expected, services
+ * should call #GNUNET_SERVICE_client_disable_continue_warning() to
+ * disable the warning.
+ *
+ * Clients sending invalid messages (based on @a handlers) will be
+ * dropped. Additionally, clients can be dropped at any time using
+ * #GNUNET_SERVICE_client_drop().
+ *
+ * The service must be stopped using #GNUNET_SERVICE_stoP().
+ *
+ * @param service_name name of the service to run
