# <a name='synopsis'></a>SYNOPSIS

package require Tcl 8\.5 9  
package require TclOO  
package require tcl::chan::events ?1\.1?  
package require tcl::chan::random ?1\.1?  

[__::tcl::chan::random__ *seed*](#1)  

# <a name='description'></a>DESCRIPTION

The __tcl::chan::random__ package provides a command creating random
channels, i\.e\. read\-only channels which return an infinite stream of
pseudo\-random characters upon reading\. This is similar to the random channels
provided by the package __Memchan__, except that this is written in pure
Tcl, not C, and uses a much simpler generator as well\. On the other hand,
__Memchan__ is usable with Tcl 8\.4 and before, whereas this package requires
Tcl 8\.5 or higher, and TclOO\.

The internal __[TclOO](\.\./\.\./\.\./\.\./index\.md\#tcloo)__ class implementing
the channel handler is a sub\-class of the
__[tcl::chan::events](\.\./virtchannel\_core/events\.md)__ framework\.

# <a name='section2'></a>API

  - <a name='1'></a>__::tcl::chan::random__ *seed*

    This command creates a new random channel and returns its handle\. The seed
    is a list of integer numbers used to initialize the internal feedback shift
    register of the generator\.

# <a name='section3'></a>Bugs, Ideas, Feedback

This document, and the package it describes, will undoubtedly contain bugs and
other problems\. Please report such in the category *virtchannel* of the
[Tcllib Trackers](http://core\.tcl\.tk/tcllib/reportlist)\. Please also report
any ideas for enhancements you may have for either package and/or documentation\.

When proposing code changes, please provide *unified diffs*, i\.e the output of
__diff \-u__\.

Note further that *attachments* are strongly preferred over inlined patches\.
Attachments can be made by going to the __Edit__ form of the ticket
immediately after its creation, and then using the left\-most button in the
secondary navigation bar\.
