________________________________________________________________________________________________________________


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.
