Function Documentation

void randomReset

(

)

Resets the random seed using the current time so, in principle, the reset is hard to predict.

Definition at line 18 of file random.c.

void randomSet

(

unsigned int

seed

)

Sets the random to the given value. This is used to get repetitive sequences of random numbers in order to debug mainly.

Parameters

seed	The new random seed.
