There are several different variations on how to get random numbers in C.

On most System V based systems and when using ANSI C you would use the 
function srand() to provide a random number seed (if you want one) and 
the rand() function to get a randon number back.

	unsigned int	seed;
	int		num;

	seed = ???;
	srand(seed);
	num = rand();


On most BSD derived systems you would use srandom() to provide the seen and 
the random() function to get the random number back.


	int		seed;
	long		num;

	seed = ???;
	srandom(seed);
	num  = random();
