tcl::chan::null - Null channel
The tcl::chan::null package provides a command creating null channels, i.e. write-only channels which immediately forget whatever is written to them. This is equivalent to the null channels provided by the package Memchan, except that this is written in pure Tcl, not C. On the other hand, Memchan is usable with Tcl 8.4 and before, whereas this package requires Tcl 8.5 or higher, and TclOO.
This document, and the package it describes, will undoubtedly contain bugs and other problems. Please report such in the category virtchannel of the Tcllib Trackers. Please also report any ideas for enhancements you may have for either package and/or documentation.
