63<H2>Description</H2>
64<p>
65Asynchronously opens a file. Proper access rights are required to open a file. You can't open files if you don't have permission to access those files. <code>NAND_RESULT_BUSY</code> is returned and this function call is denied when the queue for accepting requests inside the library is full.
