Errata for The C Programming Language, Second Edition 
This lists all known errors in The C Programming Language, Second Edition, by Brian Kernighan and Dennis Ritchie (Prentice-Hall, 1988). 

The pagination of the book has changed only in minor ways across printings of the English-language edition. These errata now include section numbers, which are more likely to be preserved across translations. This might help identify errors that survive into translated editions. 



Changes between first and second printing:
The first printing of the book was made before the Standard was finalized; these copies say "Based on Draft-Proposed ANSI C" on the front cover. All subsequent printings are identified by a large red ``ANSI C'' on the right center of the cover. Fortunately, the changes are minor; some repair our bugs, a few account for last-minute changes in the draft standard. These changes were made so early that they probably do not apply to you.

Here's how this works:

• Include a git_hooks/ directory in your project, with these two files (plus other hooks if you want, written in a similar style).
• Add "npm" to your devDependencies in package.json, so that the pre-commit hook can do its magic.
• Add test and lint scripts to your package.json, e.g.

    "scripts": {
        "test": "mocha",
 "lint": "jshint ./lib --show-non-errors"

Introduction

The MCP23017 is an I/O expander chip. It has 16 GPIO pins which you can control using an I2C interface using two pins from a Raspberry Pi, plus a power source and sink (which can also come from the Pi). It's not quite as simple as directly controlling the Pi's GPIO pins, but it's not complicated, either.

You need to install i2c-tools, which is probably in your distribution's package manager. You also need a kernel with I2C support; you might need to modprobe i2c-dev. It would presumably be possible to do without either of these things, and bitbang the I2C protocol over GPIO, but I don't understand the protocol well enough to try.

On pin numbering: if you like, you can refer to the datasheet for the MCP23017. There's a small dot in one corner of the chip, with a semi-circular cut-out at that end. The pin near
