40<h2>Return Values</h2>
41<p>
42Returns the number of bytes for the written data when the write is successful. When the write fails, one of the following codes is returned:
43<p>
44<code>NAND_RESULT_ACCESS<br> NAND_RESULT_ALLOC_FAILED<br> NAND_RESULT_AUTHENTICATION<br> NAND_RESULT_BUSY<br> NAND_RESULT_CORRUPT<br> NAND_RESULT_ECC_CRIT<br> NAND_RESULT_INVALID<br> NAND_RESULT_MAXBLOCKS<br> NAND_RESULT_UNKNOWN<br> NAND_RESULT_FATAL_ERROR<br></code>
