|
|
The [package 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 [package Memchan], except |
|
that this is written in pure Tcl, not C, and uses a much simpler |
|
generator as well. On the other hand, [package Memchan] is usable with |
|
Tcl 8.4 and before, whereas this package requires Tcl 8.5 or higher, |
|
and TclOO. |
|
|
|
[para] The internal [package TclOO] class implementing the channel |
|
handler is a sub-class of the [package tcl::chan::events] framework. |

[call [cmd ::tcl::chan::random] [arg 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. |
