The C Containers library project aims to replicate most of the 
functionality of C++ STL in C.

This project is available at


http://code.google.com/p/ccl/

All source code is freely available, with no restrictions for either 
personal or commercial use.

Available containers are lists, flexible arrays, string container, hash 
tables, and many others.

Why reinvent the wheel?

Download the ccl and enjoy.
