Suggestions of excellent examples of real C C code

Question

I'd like to study some good C/C++ code. The code should:

1. be good in style and structure, presenting best practices
2. be a real-life program (not an example or toy)
3. not too big so it doesn't take ages to analyze it
4. Windows and/or Unix

I know there are 1000s of open-source projects out there. But I'd like to hear your suggestions.

Answer 1

I'd like to particularly bring up memcached.  It's an excellent illustration of a relatively short, legible code with a distinct purpose.

The Apache web server is the second thing I would suggest. You'll learn a lot from this incredibly well-run open-source project about the language, as well as about general design principles and networking/threading.

I hope this helps you.
