tcl::chan::zero(n) 1 "Reflected/virtual channel support"
tcl::chan::zero - Zero channel
- package require Tcl 8.5
- package require TclOO
- package require tcl::chan::events ?1?
- package require tcl::chan::zero ?1?
The tcl::chan::zero package provides a command creating zero channels, i.e. read-only channels which return an infinite stream of null characters upon reading. This is equivalent to the zero 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.
