ercb v1.0.0

For those who don't like the node (er, result) convention

ercb Build Status devDependency Status

For those who don't like the node (er, result) convention.


Pass the result of calling ercb to a node function that expects an (er, result) signature. e.g.

var fs = require("rs")
  , ercb = require("ercb")

fs.readFile("somefile.txt", ercb(
  function (data) {
    // Success callback
  function (er) {
    // Failure callback
