NAME
       rand, srand - random number generator

SYNOPSIS
       srand(seed)
       int seed;

       rand()

DESCRIPTION
       The  newer  random(3)  should be used in new applications; rand remains
       for compatibilty.

       _R_a_n_d uses a multiplicative congruential random  number  generator  with
       period  2**32  to  return successive pseudo-random numbers in the range
       from 0 to (2**31)−1

       The generator is reinitialized by calling _s_r_a_n_d with 1 as argument.  It
       can  be  set  to a random starting point by calling _s_r_a_n_d with whatever
       you like as argument.
