Gio.DBusConnection.export_menu_model

### Method

# Gio DBusConnectionexport_menu_model

since: 2.32

#### Declaration [src]

    guint
    g_dbus_connection_export_menu_model (
      GDBusConnection* connection,
      const gchar* object_path,
      GMenuModel* menu,
      GError** error
    )

#### Description [src]

Exports `menu` on `connection` at `object_path`.

The implemented D-Bus API should be considered private. It is subject to change in the future.

An object path can only have one menu model exported on it. If this constraint is violated, the export will fail and 0 will be returned (with `error` set accordingly).

Exporting menus with sections containing more than `G_MENU_EXPORTER_MAX_SECTION_SIZE` items is not supported and results in undefined behavior.

You can unexport the menu model using `g_dbus_connection_unexport_menu_model()` with the return value of this function.

Available since: 2.32

#### Parameters

`object_path`

  Type: `const gchar*`

  A D-Bus object path.

  The data is owned by the caller of the method.
  The value is a NUL terminated UTF-8 string.

`menu`

  Type: `GMenuModel`

  A `GMenuModel`.

  The data is owned by the caller of the method.

`error`

  Type: `GError **`

  The return location for a recoverable error.

  The argument can be `NULL`.
  If the return location is not `NULL`, then you must initialize it to a `NULL` `GError*`.
  The argument will be left initialized to `NULL` by the method if there are no errors.
  In case of error, the argument will be set to a newly allocated `GError`; the caller will take ownership of the data, and be responsible for freeing it.

#### Return value

Type: `guint`

The ID of the export (never zero), or 0 in case of failure.
