    int
    DB->get_lk_exclusive(DB *db, int *onoff, int *nowait);

Returns whether the database handle is configured to obtain a write lock on the entire database. This can be set using the DB->set_lk_exclusive() method.

The `DB->get_lk_exclusive()` method may be called at any time during the life of the application.

The `DB->get_lk_exclusive()` always returns `0`.

### Parameters

#### onoff

Indicates whether the handle is configured for exclusive database locking. If `0`, it is not configured for exclusive locking. If `1`, then it is configured for exclusive locking.

#### nowait
