tcl::chan::variable - In-memory channel using variable for storage
SYNOPSIS
package require Tcl 8.5
package require TclOO
package require tcl::chan::events ?1?
package require tcl::chan::variable ?1?
::tcl::chan::variable varname
_________________________________________________________________DESCRIPTION
The tcl::chan::variable package provides a command creating channels
which live purely in memory. They provide random-access, i.e. are seek‐
able. 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 han‐
dle. The content of the channel is stored in the associated
namespace variable varname.
