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 compatabilty.

     rand uses a multiplicative congruential random number gen-
     erator 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 srand with 1 as
     argument.  It can be set to a random starting point by cal-
     ling srand with whatever you like as argument.
