Function Documentation

int find_frag	(	unsigned int *	seed_p,
		int	total_frags
	)

The function is called for each result to determine which fragment will have the result.

Parameters:

	seed_p	Pointer to the seed to generate pseudo-random output.
	total_frags	Fragment count.

Returns:

The index of the fragment which has this result.

int generate_int_range	(	unsigned int *	seed_p,
		int	min,
		int	max
	)

Generate a pseudo-random integer between min and max.

Parameters:

	seed_p	Pointer to the seed to generate pseudo-random output.
	min	Minimum integer value
	max	Maximum integer value

Returns:

The pseudo-random integer in betwen min to max.

double generate_rand_zero_one

(

unsigned int *

seed_p

)

Generate a pseudo-random double between 0 and 1.

Parameters:

seed_p

Pointer to the seed to generate pseudo-random output.

Returns:

The pseudo-random double in between 0 to 1.
