tcl::chan::std — Standard I/O, unification of stdin and stdout

Synopsis

package require Tcl 8.5

package require TclOO

package require tcl::chan::core ?1?

package require tcl::chan::std ?1?

::tcl::chan::std

Description

The tcl::chan::std package provides a command creating a standard channel which unifies stdin and stdout into a single read- and writable channel. The result is not seek-able, like the original standard channels.

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

API

::tcl::chan::std
This command creates the std channel and returns its handle.

The channel is created only once, on the first call, and all future calls simply return this handle.
