__________________________________________________________________________________________________________________________________________________NAME
null - Create and manipulate null channels
SYNOPSIS
package require Tcl
package require memchan
null
_________________________________________________________________DESCRIPTION
The command described here is only available in a not-yet released version of the package. Use the CVS to get the sources.
null creates a null channel which absorbs everything written into it. Reading from it is not possible, or rather will always return zero
bytes. These channels are essentially Tcl-specific variants of the null device for unixoid operating systems (/dev/null). Transfer-
ing the generated channel between interpreters is possible but does not make much sense.
OPTIONS
Memory channels created by null provide one additional option to set or query.
-delay ?milliseconds?
A null 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.
A null channel is always writable and never readable. This means that a writable fileevent-handler will fire continuously and a readable
fileevent-handler never at all. The exception to the latter is only the destruction of the channel which will cause the delivery of an eof
event to a readable handler.
