This is a node.js module, written in C++, that compares two buffers. For now it implements just eqBuf to test if two buffers are equal, fast.

It was written by Peteris Krumins ( His blog is at -- good coders code, great reuse.

The module exports one function:

* eqBuf - given two buffers, compare if they are equal.

Example usage:

var eqBuf = require('bufferdiff');
// ...
if (eqBuf(buf1, buf2)) {
    sys.log('buffers buf1 and buf2 are equal');

How to compile?

As usual,

node-waf configure build

The module will be called bufferdiff.node. To use it, make sure it's in NODE_PATH.

Extra info

This library was written for my and SubStack's StackVM startup:

Yo dawg, I heard you liked buffers so I put a buffer in yo buffer so you can compare while you compare.
