zero(3tcl)zero(3tcl)NAME
zero - Create and manipulate zero channels
SYNOPSIS
package require Tcl
package require memchan
zero
DESCRIPTION
The command described here is only available in a not-yet released version of the package. Use the CVS to get the sources.
zero creates a zero channel which absorbs everything written into it. Reading from a zero channel will return the requested number of
null bytes. These channels are essentially Tcl-specific variants of the zero device for unixoid operating systems (/dev/zero).
Transferring the generated channel between interpreters is possible but does not make much sense.
OPTIONS
Memory channels created by zero provide one additional option to set or query.
-delay ?milliseconds?
A zero channel is always writable and readable. This means that all fileevent-handlers will fire continuously. To avoid starvation
of other event sources the events raised by this channel type have a configurable delay. This option is set in milliseconds and
defaults to 5.
