Description

The DbEnv.lock_get method acquires a lock from the lock table, returning information about it in a DbLock object.

The locker argument specified to DbEnv.lock_get is an unsigned 32-bit integer quantity. It represents the entity requesting or releasing the lock.

The flags value must be set to 0 or the following value:

• Db.DB_LOCK_NOWAIT

If a lock cannot be granted because the requested lock conflicts with an existing lock, return immediately instead of waiting for the lock to become available.

The obj argument is an untyped byte string that specifies the object to be locked or released.Applications using ...
