dns.resolve6(hostname, callback) Uses the DNS protocol to resolve a IPv6 addresses (AAAA records) for the hostname. The addresses argument passed to the callback function will contain an array of IPv6 addresses.

Class: stream.Readable The Readable stream interface is the abstraction for a source of data that you are reading from. In other words, data comes out of a Readable stream. A Readable stream will not start emitting data until you indicate that you are ready to receive it. Readable streams have two "modes": a flowing mode and a paused mode. When in flowing mode, data is read from the underlying system and provided to your program as fast as possible. In paused mode, you must explicitly call st

socket.setKeepAlive([enable][, initialDelay]) Enable/disable keep-alive functionality, and optionally set the initial delay before the first keepalive probe is sent on an idle socket. enable defaults to false. Set initialDelay (in milliseconds) to set the delay between the last data packet received and the first keepalive probe. Setting 0 for initialDelay will leave the value unchanged from the default (or previous) setting. Defaults to 0. Returns socket.

buf.writeIntBE(value, offset, byteLength[, noAssert])

zlib.createInflateRaw(options) Returns a new InflateRaw object with an options.

crypto.pbkdf2(password, salt, iterations, keylen[, digest], callback) Provides an asynchronous Password-Based Key Derivation Function 2 (PBKDF2) implementation. A selected HMAC digest algorithm specified by digest is applied to derive a key of the requested byte length (keylen) from the password, salt and iterations. If the digest algorithm is not specified, a default of 'sha1' is used. The supplied callback function is called with two arguments: err and derivedKey. If an error occurs, err wil

Stability: 2 - Stable A stream is an abstract interface implemented by various objects in Node.js. For example a request to an HTTP server is a stream, as is process.stdout. Streams are readable, writable, or both. All streams are instances of EventEmitter. You can load the Stream base classes by doing require('stream'). There are base classes provided for Readable streams, Writable streams, Duplex streams, and Transform streams. This document is split up into 3 sections: The first section e

dns.resolveSrv(hostname, callback) Uses the DNS protocol to resolve service records (SRV records) for the hostname. The addresses argument passed to the callback function will be an array of objects with the following properties: priority weight port name { priority: 10, weight: 5, port: 21223, name: 'service.example.com' }

process.uptime() Number of seconds Node.js has been running.

Event: 'close' function () { } Emitted when the server closes.
