package require Tcl 8.5
package require TclOO
package require tcl::chan::events ?1?
package require tcl::chan::nullzero ?1?
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.
