I have one requirement in one of my projects, where I have to deal with lots of data. Typically huge, dynamic arrays in C.
I searched but I have not been able to find what I need.
I am looking for a usable library, which encapsulates the details of list implementation in C, and provides various functions for List manipulation.
I am aware that we can create such implementation in C, using pointers.
I have followed below links:
C generic linked-list
Generic list manipulation function in C?
Thanks in advance.
May be this small library is what you need.
It is a generic list implementation in C. glist

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 wonder if there is an alternative for the std::vector in C? I found this implementation but it seems to contain some issues with memory reallocation.
You can give glib and its arrays (GArray) a try.
glib is actively maintained, cross platform, open source (LGPLv2+), and it doesn't stop on arrays/vectors. You also have hash tables, linked lists, queues and many other data structures.
While reading C Array vs. C++ Vector, I found an interesting implementation of a simple vector container in C, which also includes push/pop operations. It's worth reading it!
If you focus is on mathematics you can work with GSL, there have a more bare bones math centric concept.

I'm thinking of something like glib, but possibly a slim version with a minimal foot print. It would need basic utilities such as linked lists, vectors and hash tables. It should also have a minimal runtime footprint.
Not exactly a library, but a tested, optimized and documented piece of code: sys/queue.h on *BSD and Linux systems has macros for various kinds of intrusive linked lists and queues.
uthash is a nice hash table library (made entirely of macros), it also comes with a linked list, dynamic string and dynamic array macros.
I also highly recommend sys/queue.h (suggested by larsmans) for simple and well tested linked lists.

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.

What are good libraries for C with datastructures like vectors, deques, stacks, hashmaps, treemaps, sets, etc.? Plain C, please, and platform-independent.
The Glib library used on the Gnome project may also be some use. Moreover it is pretty well tested.
IBM developer works has a good tutorial on its use: Manage C data using the GLib collections
As always, Google is your friend:
http://nixbit.com/cat/programming/libraries/c-generic-library/
specifically:
http://nixbit.com/cat/programming/libraries/generic-data-structures-library/
There's some stuff in the Apache Portable Runtime (APR) that I'd expect to be very solid.
Maybe http://sglib.sourceforge.net/ if you want an easy to use, very fast, macro based library.
If hash tables, extensible strings and dynamic vector are enough for your needs, please have a look at the library I put toghether: http://code.google.com/p/c-libutl/.
I also would welcome any feedback!
