DESCRIPTION

15       The  newer  random(3)  should be used in new applications; rand remains
16       for compatibilty.
17
18       Rand uses a multiplicative congruential random  number  generator  with
19       period  2**32  to  return successive pseudo-random numbers in the range
20       from 0 to (2**31)−1 on the VAX, and (2**15)−1 on the PDP-11.
21
22       The generator is reinitialized by calling srand with 1 as argument.  It
23       can  be  set  to a random starting point by calling srand with whatever
24       you like as argument.
