DESCRIPTION

24       The  tcl::chan::nullzero  package provides a command creating channels,
25       which are a combination of null and zero devices. They immediately for‐
26       get  whatever  is  written  to  them, and on reading return an infinite
27       stream of null characters.
28
29       Packages related to this are tcl::chan::null and tcl::chan::zero.
30
31       The internal TclOO class implementing the channel  handler  is  a  sub-
32       class of the tcl::chan::events framework.
