ucpp is a C preprocessor. It is designed to be quick and light, but still fully compliant to the ISO standard 9899:1999, also known as C99. ucpp can be compiled as a stand-alone program or linked to some other code; in the latter case, ucpp will output tokens, one at a time, on demand, as an integrated lexer. ucpp operates in two modes: in lexer mode, ucpp is linked to some other code and outputs a stream of tokens where each call to the lex() function will yield one token; in non-lexer mode, ucpp preprocesses text and outputs the resulting text to a file descriptor. If linked to some other code, the cpp() function must be called repeatedly, otherwise ucpp is a stand-alone binary.
Concurrency Kit provides a plethora of concurrency primitives and lock-less and lock-free data structures designed to aid in the design and implementation of high performance scalable concurrent systems. It was designed to minimize dependencies on operating system-specific interfaces, and most of the interface relies only on a strict subset of the standard library and more popular compiler extensions.
cpuid.c is a very simple C abstraction that provides an interface to common cpuid feature flags. It can be useful when implementing dynamic CPU feature dispatch that relies on optional processor feature extensions or basic processor-specific variables. This package is meant to be a very simple feature detection interface that you can easily integrate into your project. It is not meant to be complex and it is geared for projects implementing dynamic CPU feature dispatch.
downtimed is a program that monitors operating system downtime, uptime, shutdowns, and crashes and records such events. At OS startup it logs information about previous downtime. It then periodically updates a time stamp file on the disk, which is used to determine the approximate time when the system was last up and running. During a graceful system shutdown, it records a time stamp in another file. The downtimes(1) command line tool can be used to inspect records of past downtime.
hwloc provides command line tools and a C API to obtain the hierarchical map of key computing elements, such as: NUMA memory nodes, shared caches, processor sockets, processor cores, and processor "threads". hwloc also gathers various attributes such as cache and memory information, and is portable across a variety of different operating systems and platforms. hwloc primarily aims at helping high-performance computing (HPC) applications, but is also applicable to any project seeking to exploit code and/or data locality on modern computing platforms.
libdrizzle is the client and protocol library for the Drizzle project. The drizzled server will use this as the protocol library, as will the client utilities and any new projects that require low-level protocol communication (like proxies). It is designed to be used for other language interfaces such as PHP extensions and with SWIG.
