SYNOPSIS

       package require Tcl  8.5

       package require TclOO

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  class  implementing  the  channel  handler  is  a  sub-class  of  the
       tcl::chan::events framework.

API

       ::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.
