DESCRIPTION

       The  tcl::chan::nullzero  package  provides  a  command  creating  channels,  which  are a
       combination of null and zero devices. They immediately forget whatever is written to them,
       and on reading return an infinite stream of null characters.

       Packages related to this are tcl::chan::null and tcl::chan::zero.

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

API

       ::tcl::chan::nullzero
              This command creates a new nullzero channel and returns its handle.
