<p>The Force Buffered Data (QHFFRCSF) API synchronously forces buffered data and directory entry information out of main storage and into nonvolatile storage for either a specific file or all files opened by a job. (Nonvolatile storage is any storage area whose contents are not lost when power is cut off or when the system is loaded.) Forcing buffered data is similar to closing a file because the data is forced. However, after a force operation, the file remains open, and forcing has no effect on locks and read/write positions.</p>

<!-- Please NOTE: DO NOT DELETE THIS SECTION if this API has no authorities and locks. -->
