SYNOPSIS

package require Tcl

package require memchan

zero


   








\L’|0u-1v’\l’75u+3n_’\L’0u+1v-0u’\l’|0u-1.5n_’



\L’|0u-1v’\L’0u+1v-0u’\l’|0u-1.5n_’





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.
