While it does have to do with /dev/random, it has nothing to do with
rand(), srand(), random(), or srandom(). These are pseudo-random number
generators and don't need true random input. In fact these functions are
*required* to produce the same sequence of "random" numbers each time they
are seeded with the same value. (If you don't supply a seed, they are
seeded with 1.)
If you want *real* randomness (e.g., for crypto purposes), or if you want
a truly random seed for rand() and random(), you can get it by reading
from /dev/random.
