DESCRIPTION
The tcl::chan::nullzero package provides a command creating channels,
which are a combination of null and zero devices. They immediately for-
get 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 han-
dle.
