NAME

       fifo2 - Create and manipulate pipe fifo channels

SYNOPSIS

       package require Tcl

       package require memchan

       fifo2

_________________________________________________________________

DESCRIPTION

       The command described here is only available in a not-yet released version of the package. Use the CVS to get the sources.

       fifo2  creates two stream-oriented in-memory channels and returns their handles as a two-element list. There is no restriction on the ulti-
	      mate size of the channels, they will always grow as much as is necessary to accomodate the data written into them.

	      In contrast to the channels generated by fifo a pair of channels created here is connected internally in such a way that data  writ-
	      ten  into one channel can be read from the other. All data written into them is read in the same order. This also means that the two
	      channels of the pair are not seekable.

	      The channels created here can be transfered between interpreters in the same thread and between threads. As  both  channels  in  the
	      pair can be transfered independently they can be used to create a bidirectional connection between two interpreters.

       Memory channels created by fifo2 provide two read-only options which can be queried via the standard fconfigure command. These are

       -rlength
	      The value of this option is the number of bytes currently available for reading from the channel.

       -wlength
	      The value of this option is the number of bytes currently written into the channel.

       Note  that  the two lengths are switched for the channels of a pair. In other words, the number of bytes written for one of the channels is
       the number of bytes readable from the other end.

       As the channels generated by fifo2 grow as necessary they are always writable. This means that a writable fileevent-handler will fire  con-
       tinuously.

       The  channels are also readable if they contain more than zero bytes. Under this conditions a readable fileevent-handler will fire continu-
       ously.
