Db::get_ext_file_dir(const char **dirp);  

The Db::get_ext_file_dir() method returns the directory location where external file data is stored. The default location can be set using Db::set_ext_file_dir() . Use this method only if the database was not opened in an environment. If the database was opened within an encompassing environment, use DbEnv::get_ext_file_dir() instead.

The Db::get_ext_file_dir() method always returns 0 to indicate success.
