Are there any C-language static analysers out there that create graphical diagrams of the data structures in a body of C code?
I'm thinking along the lines of the data displays in the DDD (Data Display Debugger) but that work from static analysis of the source code.
Any diagram notation welcome (UML etc.) and it can run on any platform.
Thanks.
Take a look at Enterprise Architect. It is fairly inexpensive and does just this and comes with a 30 day free trial. And no, I don't work for them :) .
Understand is also a great tool for diagraming existing C / C++ code, to help you understand it.

I'm trying to make a fractal image in C. What is the best way to convert a computed matrix to an image? Is there a built-in library or must I use an external one.. if so any suggestions?
The GD library is basic but still quite useful. (It's embedded into the PHP language.)
Or, if you don't want to rely on external libraries, output your data to a text format like PPM, and then convert it to a different format in your favourite graphics editor (or a tool like ImageMagick).

I've been looking for a small YAML/JSON parser, preferably a single-file solution, so i can easily embed it on my application. I'm looking for a small and simple solution since i intend to use it on different platforms, and building libyaml and other solutions will be a huge pain in the ass.
Also, is TinyXML a good alternative? What is fastest to parse?
I was looking for something similar sometime last year. This is the one I settled on:
YAJL
It's not a single file solution, but it's not very big either. I has some features like JSON formatting and syntax checking that you might see as feature bloat, but they don't bother me.

I need to encrypt a char* string in C using blowfish or twofish in Windows.
I can't find a straight forward solution for that.
I don't want to install something like OpenSSL; I need it be a standalone as possible.
Unfortunately Googling for C code results in C# and C++ code.
Can anyone give me a straightforward function for encryption/decryption?
Have you taken a look at "https://www.schneier.com/twofish-download.html" on Bruce Schneier web site? He has reference implementations, as well as optimized implementations of the algorithm. It's been a few years since I looked at it, but you might find it useful.

I have knowledge of sql-server but i am trying to learn Sybase, I need some basic help in that, please ignore if my questions are too silly.
Where can i get this database (sybase) for practice, I went on the official site, but it asks me to fill lot of details, is it changeable ?
2.Can you please suggest a basic book for this?
How different is it form SQL-Server?
For a free product it's the least you can do to fill in a form
No. I learnt from online help.
SQL Server was actually built from Sybase many years ago back at version 6.0 (maybe 25 years ago) but has now of course branched off. You'll find a lot of the functions are the same.

I need to do some work with this library and I'm finding the documentation at http://apodeline.free.fr/DOC/libjpeg/libjpeg.html to be deficient (incomplete function signatures, etc). Does anyone know of some other sides or have some example code illustrating common tasks?
[Edit]
I also found this question with an example, but any others would be helpful.
Try using libjpeg library. Example how to use it is in this blog.
I don't know what you're using, but we use the C++ wrapper at Smaller Animals Software, and we're happy with it. If nothing else, it might work as example code.
