Closing a Database

The DB→close function is the standard interface for closing the database. By default, DB→close also flushes all modified records from the database cache to disk. There is one flag that you can set to customize DB→close:

• DB_NOSYNC Do not flush cached information to disk.

It is important to understand that flushing cached information to disk only minimizes the window of opportunity for corrupted data; it does not eliminate the possibility.
