Using sizeof Correctly with Byte[]

Question

I\'m sort of out of my depths here, but I have the following code (the real code actually has a point of course):

- (NSData*) dataTheseBytes:(Byte[]) bytes {         


        

Answer 1

You cannot pass arrays to a function. You're passing a pointer to the first element in the array of the caller.

If you need the length of that array, you need to pass that length as a separate argument to your function, and use that instead of sizeof
