Db::get_blob_threshold(u_int32_t *bytes);  

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

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