NAME¶
random - Create and manipulate randomizer channels
SYNOPSIS¶
package require
Tcl
package require
memchan
random
DESCRIPTION¶
- 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.
OPTIONS¶
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.
