75<H2>Description</H2>
76<p>
77Obtains the status of the file or directory asynchronously. This requires the appropriate read permission for the parent directory of the file or directory in question. <code>NAND_RESULT_BUSY</code> is returned and this function call is denied when the queue for accepting requests inside the library is full.
