  * atspi_accessible_get_process_id:
  * @accessible: The #AtspiAccessible to query.
+ * @error: a pointer to a %NULL #GError pointer

  * Returns the process id associated with the given accessible.  Mainly
  * added for debugging; it is a shortcut to explicitly querying the
  * accessible's app->bus_name and then calling GetConnectionUnixProcessID.
  *
- * Returns: The process ID, or -1 if defunct.
+ * Returns: The process ID or undetermined value if @error is set.
