Returns array of pseudo random integers of machine-dependent size
public static randomInts ( integer $numInts, callable $cb, integer $pri, boolean $hang = false ) : integer
$numInts integer Number of integers
$cb callable Callback
$pri integer Priority of EIO operation
$hang boolean If true, we shall use /dev/random instead of /dev/urandom and it may cause a delay
