| public static randomString ( integer $len = null, string $chars = null, callable $cb = null, integer $pri, boolean $hang = false ) : string | ||
| $len | integer | Length of desired string |
| $chars | string | String of allowed characters |
| $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 |
