Method

GUPnPServiceProxyActionget_result_list

Declaration [src]

gboolean
gupnp_service_proxy_action_get_result_list (
  GUPnPServiceProxyAction* action,
  GList* out_names,
  GList* out_types,
  GList** out_values,
  GError** error
)

Description [src]

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;

                                                     &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");

             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`	A list of `utf8`
	`GList` of ‘out’ parameter names (as strings)
	The data is owned by the caller of the function.
	Each element is a NUL terminated UTF-8 string.
`out_types`	A list of `GType`
	`GList` of types (as `GType`) that line up with `out_names`.
	The data is owned by the caller of the function.
`out_values`	A list of `const GValue*`
	`GList` of values (as `GValue`) that line up with `out_names` and `out_types`.
	The argument will be set by the function.
	The instance takes ownership of the data, and is responsible for freeing it.
`error`	`GError **`
	The return location for a `GError*`, or `NULL`.

Return value

Returns:	`gboolean`
	`TRUE` on success.
