DESCRIPTION

24       The  tcl::chan::variable  package  provides a command creating channels
25       which live purely in memory. They provide random-access, i.e. are seek‐
26       able.   In  contrast  to the channels created by tcl::chan::memchan the
27       data is not hidden in the channel however, but stored in an  associated
28       variable, specified at the time of construction.
29
30       Packages related to this are tcl::chan::memchan and tcl::chan::string.
31
32       The  internal  TclOO  class  implementing the channel handler is a sub-
33       class of the tcl::chan::events framework.

API

36       ::tcl::chan::variable varname
37              This command creates a new variable channel and returns its han‐
38              dle.   The  content  of  the channel is stored in the associated
39              namespace variable varname.
