Functions
void	sg_srandom_time ()
	Seed the random number generater with time() so we don't see the same sequence every time.
void	sg_srandom_time_10 ()
	Seed the random number generater with time() in 10 minute intervals so we get the same sequence within 10 minutes interval.
void	sg_srandom (unsigned int seed)
	Seed the random number generater with your own seed so can set up repeatable randomization.
double	sg_random ()
	Return a random number between [0.0, 1.0).

void sg_srandom

(

unsigned int

seed

)

Seed the random number generater with your own seed so can set up repeatable randomization.

Parameters:

seed

random number generator seed

void sg_srandom_time_10

(

)

Seed the random number generater with time() in 10 minute intervals so we get the same sequence within 10 minutes interval.

This is useful for synchronizing two display systems.
