random
-
creates a random channel which absorbs everything written into it and
uses it as a seed for a random number generator. This generator is
used to create a random sequence of bytes when reading from the
channel. It is not possible to seek the channel.
Memory channels created by
random provide one additional option to
set or query.
- -delay ? milliseconds ?
-
A random channel is always writable and readable. This means
that all fileevent-handlers will fire continuously. To
avoid starvation of other event sources the events raised by this
channel type have a configurable delay. This option is set in
milliseconds and defaults to 5.
