::tcl::chan::std

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.

When proposing code changes, please provide unified diffs, i.e the output of diff -u.

Note further that attachments are strongly preferred over inlined patches. Attachments can be made by going to the Edit form of the ticket immediately after its creation, and then using the left-most button in the secondary navigation bar.
