This function flushes data written to a database volume on a remote Windows Embedded CE–based device to permanent storage.
In a mounted database volume, all write operations are cached. To explicitly force the data to be written out to permanent storage, the CeFlushDBVol method must be called. If a reset or power failure occurs before data is flushed from the cache, then the data that has not been flushed is lost. The database engine periodically flushes the database volume when enough data has been changed and when it is unmounted, but an application that must ensure that its data is saved should call CeFlushDBVol
