NAME¶

tcl::chan::fifo - In-memory fifo channel

SYNOPSIS¶

package require Tcl 8.5

package require TclOO

package require tcl::chan::events ?1?

package require tcl::chan::fifo ?1?

::tcl::chan::fifo

DESCRIPTION¶

The tcl::chan::fifo package provides a command creating channels which live purely in memory. Access is fifo-like, i.e. things are read out of the channel in the order they were written to it. This is equivalent to the fifo 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.

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

API¶

::tcl::chan::fifo

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