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.
