Db::get_ext_file_threshold(u_int32_t *bytes);  

The Db::get_ext_file_threshold() method returns the threshold value, in bytes, beyond which data items are stored as external files. This value can be set using Db::set_ext_file_threshold() . A value of 0 indicates that external files are not in use for this database.

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