    NAME
         rand, srand - random number generator

    SYNOPSIS

         void srand(unsigned seed)
         unsigned rand(void)

    DESCRIPTION
         Rand uses a multiplicative  congruential  random  number  generator  with
         period 2**32 to return successive pseudo-random numbers in the range from
         0 to RAND_MAX.

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