## DbEnv::get_ext_file_dir()

    #include <db_cxx.h>

    int
    DbEnv::get_ext_file_dir(const char **dirp);

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

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

### Parameters

#### dirp

The dirp parameter references memory into which is copied the path to the external file data directory. If DbEnv::set_ext_file_dir() has not been called prior to calling this method, or if external files are notsupported by this environment, then this parameter is set to NULL.
