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.
