24 The tcl::chan::random package provides a command creating random chan‐
25 nels, i.e. read-only channels which return an infinite stream of
26 pseudo-random characters upon reading. This is similar to the random
27 channels provided by the package Memchan, except that this is written
28 in pure Tcl, not C, and uses a much simpler generator as well. On the
29 other hand, Memchan is usable with Tcl 8.4 and before, whereas this
30 package requires Tcl 8.5 or higher, and TclOO.
31
32 The internal TclOO class implementing the channel handler is a sub-
33 class of the tcl::chan::events framework.
34
36 ::tcl::chan::random seed
37 This command creates a new random channel and returns its han‐
38 dle. The seed is a list of integer numbers used to initialize
39 the internal feedback shift register of the generator.

44 nel of the Tcllib Trackers [http://core.tcl.tk/tcllib/reportlist].
45 Please also report any ideas for enhancements you may have for either
46 package and/or documentation.

53 ticket immediately after its creation, and then using the left-most
