libstree is a generic suffix tree implementation, written in C. It can handle arbitrary data structures as elements of a string. Unlike most demo implementations, it is not limited to simple ASCII character strings. Suffix tree generation in libstree is highly efficient and implemented using the algorithm by Ukkonen, which means that libstree builds suffix trees in time linear to the length of the strings (assuming that string element comparisons can be done in O(1)).
