+/// @brief Add and send a new recurring diagnostic request.
+///
+/// At most one recurring request can be active for the same arbitration ID, mode
+/// and (if set) PID on the same bus at one time. If you try and call
+/// addRecurringRequest with the same key, it will return an error.
+///
+/// TODO: This also adds any neccessary CAN acceptance filters so we can receive the
+/// response. If the request is to the functional broadcast ID (0x7df) filters
+/// are added for all functional addresses (0x7e8 to 0x7f0).
+///
+/// Example:
+///
+/// // Creating a functional broadcast, mode 1 request for PID 2.
+/// DiagnosticRequest request = {
+/// arbitration_id: 0x7df,
+/// mode: 1,
+/// has_pid: true,
+/// pid: 2
+/// };
+///
+/// // Add a recurring request, to be sent at 1Hz, and published with the
+/// // name "my_pid_request"
+/// addRecurringRequest(&getConfiguration()->diagnosticsManager,
+/// canBus,
+/// &request,
+/// "my_pid_request",
+/// false,
+/// NULL,
+/// NULL,
+/// 1);
+///
+/// @param[in] request - The parameters for the request.
+/// @param[in] name - An optional human readable name this response, to be used when
+/// publishing received responses. If the name is NULL, the published output
+/// will use the raw OBD-II response format.
+/// @param[in] wait_for_multiple_responses - If false, When any response is received
+/// for this request it will be removed from the active list. If true, the
+/// request will remain active until the timeout clock expires, to allow it
+/// to receive multiple response. Functional broadcast requests will always
+/// waint for the timeout, regardless of this parameter.
+/// @param[in] decoder - An optional DiagnosticResponseDecoder to parse the payload of
+/// responses to this request. If the decoder is NULL, the output will
+/// include the raw payload instead of a parsed value.
+/// @param[in] callback - An optional DiagnosticResponseCallback to be notified whenever a
+/// response is received for this request.
+/// @param[in] frequencyHz - The frequency (in Hz) to send the request. A frequency above
+/// MAX_RECURRING_DIAGNOSTIC_FREQUENCY_HZ is not allowed, and will make this
+/// function return false.
+///
+/// @return true if the request was added successfully. Returns false if there
+/// was too much already running requests, if the frequency was too high TODO:or if the
+/// CAN acceptance filters could not be configured,
+///
