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.
