+/**
+ *  @brief
+ *    Set the proxy method for the specified service.
+ *
+ *  This attempts to set the proxy method for the specified
+ *  service. If the service is null or if the service is hidden, no
+ *  action is taken. If specified, a handler will be invoked, with the
+ *  specified context, after setting the proxy method.
+ *
+ *  If the handler is specified and it returns true, following, a
+ *  D-Bus change notification should be sent for the service "Proxy"
+ *  property and, if requested by @a donotifier, the proxy changed
+ *  notifier chain will be run.
+ *
+ *  @param[in,out]  service     A pointer to the mutable network
+ *                              service for which to set the proxy
+ *                              method.
+ *  @param[in]      method      The network service proxy method to set
+ *                              on @a service.
+ *  @param[in]      donotifier  A Boolean indicating whether the proxy
+ *                              changed notifier chain should be run
+ *                              after @a method is set on @a service.
+ *  @param[in]      handler     An optional pointer to a handler that,
+ *                              if specified, will be invoked after @a
+ *                              method is set on @a service.
+ *  @param[in]      context     An optional pointer to immutable context
+ *                              that will be passed to @a handler,
+ *                              along with @a service and @a method.
