NAME

       random - Create and manipulate randomizer channels

SYNOPSIS

       package require Tcl

       package require memchan

       random

_________________________________________________________________

DESCRIPTION

       random creates  a random channel which absorbs everything written into it and uses it as a seed for a random number generator. This genera-
	      tor is used to create a random sequence of bytes when reading from the channel. It is not possible to seek the channel.

OPTIONS

       Memory channels created by random provide one additional option to set or query.

       -delay ?milliseconds?
	      A random channel is always writable and readable. This means that all fileevent-handlers will fire continuously.	To  avoid  starva-
	      tion 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.

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.
