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.
