Methods

  • get_result_hash(out_hash: HashTable<string | number | symbol, string | number | boolean>): [boolean, HashTable<string | number | symbol, string | number | boolean>]
  • See gupnp_service_proxy_action_get_result(); this version takes a #GHashTable for runtime generated parameter lists.

    The out_hash needs to be pre-initialized with key value pairs denoting the argument to retrieve and an empty #GValue initialized to hold the wanted type with g_value_init().

    void on_action_finished(GObject *object, GAsyncResult *res, gpointer user_data) { GUPnPServiceProxyAction *action; GError *error;
    action = gupnp_service_proxy_call_action_finish (GUPNP_SERVICE_PROXY (object),
    res,
    &error);

    if (error != NULL) {
    g_print ("Call failed: %s", error->message);
    g_clear_error (&error);
    return;
    }

    GValue play_mode = G_VALUE_INIT;
    g_value_init(&play_mode, G_TYPE_STRING);
    GValue rec_quality_mode = G_VALUE_INIT;
    g_value_init(&rec_quality_mode, G_TYPE_STRING);

    GHashTable *out_args = g_hash_table_new (g_str_hash, g_str_equal);
    g_hash_table_insert(out_args, "PlayMode", &play_mode);
    g_hash_table_insert(out_args, "RecQualityMode", &rec_quality_mode);

    if (!gupnp_service_proxy_action_get_result_hash (action,
    out_args,
    &error)) {
    g_print ("Getting results failed: %s", error->message);
    g_clear_error (&error);
    return;
    }

    g_value_unset (&play_mode);
    g_value_unset (&rec_quality_mode);

    g_hash_table_unref (out_args);

    }

    Parameters

    • out_hash: HashTable<string | number | symbol, string | number | boolean>

      A #GHashTable of out parameter name and initialised #GValue pairs

    Returns [boolean, HashTable<string | number | symbol, string | number | boolean>]

  • get_result_list(out_names: string[], out_types: GType<unknown>[]): [boolean, any[]]
  • A variant of gupnp_service_proxy_action_get_result() that takes lists of out-parameter names, types and place-holders for values. The returned list in out_values must be freed using #g_list_free and each element in it using #g_value_unset and #g_free. void on_action_finished(GObject *object, GAsyncResult *res, gpointer user_data) { GUPnPServiceProxyAction *action; GError *error;

    action = gupnp_service_proxy_call_action_finish (GUPNP_SERVICE_PROXY (object),
    res,
    &error);

    if (error != NULL) {
    g_print ("Call failed: %s", error->message);
    g_clear_error (&error);
    return;
    }

    GList *out_args = NULL;
    out_args = g_list_append (out_args, "PlayMode");
    out_args = g_list_append (out_args, "RecQualityMode");
    GList *out_types = NULL;
    out_types = g_list_append (out_types, GSIZE_TO_POINTER (G_TYPE_STRING));
    out_types = g_list_append (out_types, GSIZE_TO_POINTER (G_TYPE_STRING));
    GList *out_values = NULL;

    if (!gupnp_service_proxy_action_get_result_list (action,
    out_args,
    out_types,
    &out_values,
    &error)) {
    g_print ("Getting results failed: %s", error->message);
    g_clear_error (&error);
    return;
    }

    GList *iter = out_values;
    while (iter != NULL) {
    GValue *value = iter->data;
    g_print ("Result: %s\n", g_value_get_string (value));
    g_value_unset (value);
    g_free (value);
    iter = g_list_remove_link (iter, iter);
    }
    g_list_free (out_values);

    }

    Parameters

    • out_names: string[]

      #GList of 'out' parameter names (as strings)

    • out_types: GType<unknown>[]

      #GList of types (as #GType) that line up with out_names

    Returns [boolean, any[]]

  • set(key: string, value: any): boolean
  • Update the value of key to value.

    key needs to already exist in action.

    Parameters

    • key: string

      the name of the value to modify

    • value: any

      the new value of key

    Returns boolean

  • unref(): void
  • Prepares action action with parameters in_names and in_values to be sent off to a remote service later with gupnp_service_proxy_call_action() or gupnp_service_proxy_call_action_async(). This is mainly useful for language bindings.

    After the action call has finished, the results of the call may be retrived from the #GUPnPServiceProxyAction by using gupnp_service_proxy_action_get_result(), gupnp_service_proxy_action_get_result_list() or gupnp_service_proxy_action_get_result_hash() GList *in_args = NULL; in_args = g_list_append (in_args, "InstanceID"); in_args = g_list_append (in_args, "Unit"); in_args = g_list_append (in_args, "Target");

    GValue instance = G_VALUE_INIT; g_value_set_int (&instance, 0); GValue unit = G_VALUE_INIT; g_value_set_static_string (&unit, "ABS_TIME"); GValue target = G_VALUE_INIT; g_value_set_static_string (&target, "00:00:00.000");

    GList *in_values = NULL; in_values = g_list_append (in_values, &instance); in_values = g_list_append (in_values, &unit); in_values = g_list_append (in_values, &target);

    GUPnPServiceProxyAction *action = gunp_service_proxy_action_new_from_list ("Seek", in_args, in_values);

    GError *error = NULL; gupnp_service_proxy_call_action_async (proxy, action, NULL, on_action_finished, NULL); gupnp_service_proxy_action_unref (action);

    Parameters

    • action: string

      An action

    • in_names: string[]

      #GList of 'in' parameter names (as strings)

    • in_values: any[]

      #GList of values (as #GValue) that line up with in_names

    Returns GUPnP.ServiceProxyAction
