50<h2>Return Values</h2>
51<p>
52Returns <CODE>NAND_RESULT_OK</CODE> when the request begins normally. When the read is successful, the number of bytes for the read data is passed to the callback function.

58<H2>Description</H2>
59<p>
60Asynchronously reads data from a file in Wii console NAND memory. <code>NAND_RESULT_BUSY</code> is returned and this function call is denied when the queue for accepting requests inside the library is full.
