If one of your standard references when developing C code for embedded systems designs is “C Programming FAQs: Frequently Asked Questions” published by AddisonWesley, a better and more up to date online reference is the comp.lang.c Frequently Asked Questions (FAQ) collection of web pages.

Go to the FAQ on the web and save its URL to your browser favorites list for use as a quick reference and/or as a complement to the use of the published text, or other references you use regularly. By permission of the author and the publisher the FAQ can be accessed freely for personal use but may not be published or retransmitted without explicit permission.
