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 [package Memchan], except that this is written in pure Tcl, not C. On the other hand, [package Memchan] is usable with Tcl 8.4 and before, whereas this package requires Tcl 8.5 or higher, and [package TclOO]. [para] The internal [package TclOO] class implementing the channel handler is a sub-class of the [package tcl::chan::events] framework. [section API] [list_begin definitions] [call [cmd ::tcl::chan::fifo]] This command creates a new fifo channel and returns its handle.
