| 56 | <h4>Description</h4>\r | |
| 57 | <p>The <tt>f_stat()</tt> function checks the existence of a file or sub-directory. If not exist, the function returns with <tt>FR_NO_FILE</tt>. If exist, the function returns with <tt>FR_OK</tt> and the informations of the object, file size, timestamp, attribute and SFN, are stored to the file information structure. For details of the file information, refer to the <tt>FILINFO</tt> structure and <a href="readdir.html"><tt>f_readdir()</tt></a> function.</p>\r | |
| 7b78a5a2 | 58 | <p>When LFN feature is enabled, <tt>lfname</tt> in the file information structure must be NULLed prior to use it.</p>\r |
