Libqb

libqb is a thread-safe library with the primary purpose of providing high-performance, reusable features for client-server communication. It provides high-performance logging, tracing, interprocess communication (IPC), and polling. Its goal is to provide specialized APIs that are highly tuned for maximum performance for client/server applications.
