Sorry, it was late and I was tired... Of course the code written above isn't worth to mention... > > int i; > int *ip; > > ip = &i; > get_random_bytes(&i, sizeof i); > get_random_bytes(ip, sizeof *ip); Yes, this seems to make more sense. 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 next time it gets 'ip' which is equal to the address of 'i' (ip=&i;) and should have the size of int, too (int *ip). I hope the question isn't too stupid, but I'm in a hurry (I have to go to school in a few minutes) and didn't check it with my C Reference. I do it this way because I would like to start to code the lottery scheduler this evening and the earlier I find a _working_ way to get random numbers into an integer the faster I can start with the real fun, with implementing the algorithm...
