 * @short_description: Secret Service functions which operate on DBus object paths
 *
 * These are low level functions which operate on DBus object paths of
 * collections or items, instead of the #SecretCollection or #SecretItem
 * objects themselves.
 *
 * You can use these functions if you wish to manage access to the secret
 * service using the DBus API directly, and only wish to use a few calls
 * in libsecret.

/**
 * secret_service_create_item_dbus_path_sync:
 * @self: a secret service object
 * @collection_path: the D-Bus path of the collection in which to create item
 * @properties: (element-type utf8 GLib.Variant): hash table of D-Bus properties
 *              for the new collection
 * @value: the secret value to store in the item
 * @flags: flags for the creation of the new item
 * @cancellable: optional cancellation object
 * @error: location to place an error on failure
 *
 * Create a new item in a secret service collection and return its D-Bus
 * object path.
 *
 * It is often easier to use secret_password_store_sync() or secret_item_create_sync()
 * rather than using this function. Using this method requires that you setup
 * a correct hash table of D-Bus @properties for the new collection.
 *
 * If the @flags contains %SECRET_ITEM_CREATE_REPLACE, then the secret
 * service will search for an item matching the @attributes, and update that item
 * instead of creating a new one.
 *
 * @properties is a set of properties for the new collection. The keys in the
 * hash table should be interface.property strings like
 * <literal>org.freedesktop.Secret.Item.Label</literal>. The values
 * in the hash table should be #GVariant values of the properties.
 *
 * This method may block indefinitely and should not be used in user interface
 * threads. The secret service may prompt the user. secret_service_prompt()
 * will be used to handle any prompts that are required.
 *
 * Stability: Unstable
 *
 * Returns: (transfer full): a new string containing the D-Bus object path
