I'll write up some extensive documentation about all of this, detailing use cases and our various conclusions. > - #define get_random_int (unsigned)get_random_long That's a good idea, since ultimately the other just casts in the return value. I wonder if this could also lead to a similar aliasing with arch_get_random_int, since I'm pretty sure all rdrand-like instructions return native word size anyway. > - Ted, Andy Lutorminski and I will try to figure out a construction of > get_random_long() that we all like. And me, I hope... No need to make this exclusive.
