assuming the len is 1, the following code will access the next 3
array anymore, I think it's better to check the i with len -2.

for (i = 0; i < len; i += 3) {
to 
for (i = 0; i < len - 2; i += 3) {

for the return, I think it's correct to return the used length,
if it's error, have return already. right?
