smalloc (Static memory buffer malloc) is simple malloc-like memory allocator library. It can be embedded in any existing C project, since it has no external dependencies. When given a big memory buffer, it will handle allocations from that buffer. You can also add new buffers to the allocator after it has been initialized, and smalloc will auto-merge adjacent buffers if possible. It was designed to be used in kernel-side RTLinux and RTAI modules.
Real-Time Control Systems Library contains a mix of software found to be useful in the development of real-time control systems at the National Institute of Standards and Technology. It includes the Neutral Messaging Language (NML), which is used for simple configurable communications for both Java and C++ applications on a variety of operating systems. It also includes classes for converting between various coordinate systems (collectively called posemath), some XML parsing and generating tools, an .ini file reader, a timer interface, and more.
