    class DbDeadlockException : public DbException { ... };

This information describes the `DbDeadlockException` class and how it is used by the various Berkeley DB classes.

A `DbDeadlockException` is thrown when multiple threads competing for a lock are deadlocked, when a lock request has timed out (and DB_TIME_NOTGRANTED has not been set in the environment), or when a lock request would need to block and the transaction has been configured to not wait for locks. One of the threads' transactions is selected for termination, and a `DbDeadlockException` is thrown to that thread.

The DbException errno value is set to `DB_LOCK_DEADLOCK`.
