NEW IN FILEFLEX 3.0 -- MULTI-USER VERSION ONLY This function unlocks the currently selected database file and it's associated memos and indexes. DBUnlock ruthlessly attempts to write any changes to disk before removing the file locks by forcing direct writes to the disk and doing a complete buffer flush.
Some notes on multi-user files: FileFlex will attempt to access a locked file or record at approximately one second intervals. It will continue to do so until it gains access. If we find this becomes a problem, in a future version we may allow you to set the number of access attempts or time. Also, to prevent conflict or "deadlock", be sure that all users always lock and unlock records and files in exactly the same order.
