serialization - Serialize Data Structures in C

Question

I'd like a C library that can serialize my data structures to disk, and then load them again later. It should accept arbitrarily nested structures, possibly with circular references.

I presume that this tool would need a configuration file describing my data structures. The library is allowed to use code generation, although I'm fairly sure it's possible to do this without it.

Note I'm not interested in data portability. I'd like to use it as a cache, so I can rely on the environment not changing.

Thanks.

Results

Someone suggested Tpl which is an awesome library, but I believe that it does not do arbitrary object graphs, such as a tree of Nodes that each contain two other Nodes.

Another candidate is Eet, which is a project of the Enlightenment window manager. Looks interesting but, again, seems not to have the ability to serialize nested structures.

Answer 1

Check out tpl. From the overview:

Tpl is a library for serializing C data. The data is stored in its natural binary form. The API is small and tries to stay "out of the way". Compared to using XML, tpl is faster and easier to use in C programs. Tpl can serialize many C data types, including structures.
