fs-ext

fs-ext

Extras not included in Node's fs module.

Installation

Install via npm:

npm install fs-ext

Usage

fs-ext imports all of the methods from the core 'fs' module, so you don't need two objects.

var fs = require('fs-ext');
var fd = fs.openSync('foo.txt', 'r');
fs.flock(fd, 'ex', function (err) {
    if (err) {
        return console.log("Couldn't lock file");
    }
    // file is locked
})

API

fs.flock(fd, flags, [callback])

Asynchronous flock(2). No arguments other than a possible error are passed to the callback. Flags can be 'sh', 'ex', 'shnb', 'exnb', 'un' and correspond to the various LOCK_SH, LOCK_EX, LOCK_SH|LOCK_NB, etc.

fs.flockSync(fd, flags)

Synchronous flock(2). Throws an exception on error.
