SYNOPSIS

DESCRIPTION

       The  tcl::chan::variable  package  provides a command creating channels which live purely in memory. They
       provide random-access, i.e. are seekable.  In contrast to the channels created by tcl::chan::memchan  the
       data is not hidden in the channel however, but stored in an associated variable, specified at the time of
       construction.

       Packages related to this are tcl::chan::memchan and tcl::chan::string.

       The internal TclOO class implementing the  channel  handler  is  a  sub-class  of  the  tcl::chan::events
       framework.

API

       ::tcl::chan::variable varname
              This command creates a new variable channel and returns its handle.  The content of the channel is
              stored in the associated namespace variable varname.
