multiplex

A binary stream multiplexer. Stream multiple streams of binary data over a single binary stream. Like mux-demux but faster since it only works with binary streams.

$3

Returns a new multiplexer. You can use this to create sub-streams. All data written to sub-streams will be emitted through this. If you pipe a multiplex instance to another multiplex instance all substream data will be multiplexed and demultiplexed on the other end.

onStream will be called with (stream, id) whenever a new remote sub-stream is created with an id that hasn't already been created with .createStream.

Options include:

* opts.limit - set the max allowed message size. default is no maximum

Any other options set in options are used as defaults options when creating sub streams.

$3

Creates a new sub-stream with an optional whole string id (default is the stream channel id).

Sub-streams are duplex streams.

Options include:

* opts.chunked - enables chunked mode on all streams (message framing not guaranteed)
* opts.halfOpen - make channels support half open mode meaning that they can be readable but not writable and vice versa

$3

Explicitly receive an incoming stream.

This is useful if you have a function that accepts an instance of multiplex
and you want to receive a substream.

$3

Create a shared stream. If both ends create a shared stream with
the same id, writing data on one end will emit the same data on the other end

events

$3

Emitted when the outer stream encounters invalid data

$3

Emitted when a it a new stream arrives.

$3

Emitted if the inner stream is destroyed with an error

``js
var multiplex = require('multiplex')
var plex1 = multiplex()
var stream1 = plex1.createStream()
var stream2 = plex1.createStream()

var plex2 = multiplex(function onStream(stream, id) {
stream.on('data', function(c) {
console.log('data', id, c.toString())
})
})

plex1.pipe(plex2)

stream1.write(new Buffer('stream one!'))
stream2.write(new Buffer('stream two!'))
``
