SYNOPSIS

package require Tcl 8.5 9
package require TclOO
package require tcl::chan::events ?1.1?
package require tcl::chan::memchan ?1.0.5?

::tcl::chan::memchan

DESCRIPTION

The tcl::chan::memchan package provides a command creating channels which live purely in memory. They provide random-access, i.e. are seekable. This is equivalent to the memchan channels provided by the package Memchan, except that this is written in pure Tcl, not C. On the other hand, Memchan is usable with Tcl 8.4 and before, whereas this package requires Tcl 8.5 or higher, and TclOO.

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

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

API

• ::tcl::chan::memchan

  This command creates a new memchan channel and returns its handle.
