If the file has been changed, the cached information of the file is written back to the volume. After the function succeeded, the file object is no longer valid and it can be discarded.</p> 48e6865dcdSopenharmony_ci<p>Note that if the file object is in read-only mode and <tt>FF_FS_LOCK</tt> is not enabled, the file object can also be discarded without this procedure. However this is not recommended for future compatibility.</p> 49e6865dcdSopenharmony_ci</div> 50e6865dcdSopenharmony_ci 51e6865dcdSopenharmony_ci 52e6865dcdSopenharmony_ci<div class="para comp"> 53e6865dcdSopenharmony_ci<h4>QuickInfo</h4> 54e6865dcdSopenharmony_ci<p>Always available.</p> 55e6865dcdSopenharmony_ci</div> 56e6865dcdSopenharmony_ci 57e6865dcdSopenharmony_ci 58e6865dcdSopenharmony_ci<div class="para ref"> 59e6865dcdSopenharmony_ci<h4>See Also</h4> 60e6865dcdSopenharmony_ci<p><tt><a href="open.html">f_open</a>, <a href="read.html">f_read</a>, <a href="write.html">f_write</a>, <a href="sync.html">f_sync</a>, <a href="sfile.html">FIL</a>, <a href="sfatfs.html">FATFS</a></tt></p> 61e6865dcdSopenharmony_ci</div> 62e6865dcdSopenharmony_ci 63e6865dcdSopenharmony_ci<p class="foot"><a href="../00index_e.html">Return</a></p> 64e6865dcdSopenharmony_ci</body> 65e6865dcdSopenharmony_ci</html> 66
