The only thing I'm a little bit > unsure about is why 'get_random_bytes' is called twice. The first > time it gets the address of 'i' and it's size which is int.

The sequence as a whole doesn't make sense. It is the different methods of calling it which are being shown. Given the confusion over passing an int instead of an int * I thought a comparision of the two would be helpful. You're completely correct in your understanding of those lines; the second call will trample the bytes returned by the first.
