int
DB->get_ext_file_dir(DB *dbenv, 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 DB_ENV->get_ext_file_dir() instead.

The DB->get_ext_file_dir() method always returns 0 to indicate success.
