Kazlib
Kazlib is a package of four reusable software modules that provide some frequently-needed functionality. There is a dictionary module based on red-black trees, a hashing module capable of managing hash tables that grow automatically, and a well rounded module for managing linked lists. Also a portable exception handling module. The Kazlib code is clean, highly portable and contains powerful argument validation and self-checks that help debug your own code. The algorithms are efficient for efficienty, and implemented sensibly.
