GNU's C Library The GNU C library is used as the C library in the GNU system and most newer systems with the Linux kernel. The history of Unix and various standards determine much of the interface of the C library. In general the GNU C library supports the ISO C and POSIX standards. We also try to support the features of popular Unix variants (including BSD and System V) when those do not conflict with the standards. Different compatibility modes (selectable when you compile an application) allow the peaceful coexistence of compatibility support for different varieties of Unix. hot libc Any Unix-like operating system needs a C library: the library which defines the ``system calls'' and other basic facilities such as open, malloc, printf, exit. The GNU C library is used as the C library in the GNU system and most systems with the Linux kernel. hot A'Hote A'Hote is a C++ library for creating color schemes including complements, split complements, triadics, tetradics, analogous colors, monochromatic groups, shaded groups, and tinted groups. The color scheme generators are also overloaded, allowing schemes of schemes to be generated. There are functions for converting RGB, HSB, HSL, YUV, and RYB. ABL (Atoku's Basic List) ABL (Atoku's Basic List) is a flexible abstract list library defined using the C preprocessor. It allows you to define linked lists of arbitrary types very easily. ACDK a platform independent library for generating distributed server-based components and applications Active Objects Active Objects is an implementation of the Active Object concept based on the boost::thread, boost::bind, and boost::function libraries. The point of the library is to make taking advantage of multiprocessor machines as easy as possible.

Awka a translator of the AWK language to ANSI-C, and a library against which the C code is linked Base4r Base4r is a client library for Google Base, written in Ruby. It is currently able to authenticate and to create, update, and delete Base items from your Ruby project. BeneJSON BeneJSON is a JSON input library written with a core written in C and distributed with a high level C++ interface. Bit::Vector a C library C Algorithms Library C Algorithms Library is a collection of commonly used Computer Science algorithms. The focus is on code that is well documented and tested, portable, and reusable. C Generic Library The C Generic Library is a collection of data structures designed and created in as generic a fashion as possible. Each data structure will contain its own basic memory management, be able to handle any object type, and hopefully constrain to strict algorithmic constraints. It contains doubly linked list, vector, deque, stack, queue, and binary tree structures, with list and vector based versions available for deque, stack, and queue. C++ Machine Objects The Machine Objects class library (in short Macho) supports a subset of the UML statechart notation for implementing hierarchical state machines in straight C++, similar in spirit to the GoF "State" design pattern. C++ Mork Parser MorkParser is an efficient C++ implementation of a Mork database format reader. The Mork format is used in most Mozilla-based projects, including the Mozilla browser suite, SeaMonkey, Firefox, and Thunderbird. In Firefox, it is used for browsing history data and form history data. In Thunderbird, it is used for many things, such as address book data (.mab files) and the mail folder summaries (.msf files). The MorkParser class uses Qt, therefore it is cross-platform. C++ ResourcePool a C++ library which can be used to pool resources of every kind. One very interesting side effect is that it can also be used of abstraction layer by providing a unique API for different resources of similar resource types C++ Sockets C++ Sockets is a GPL licensed C++ class library wrapping the berkeley sockets C API, and therefore works on most unixes and also win32. C++ WSDL Parser C++ WSDL Parser is a C++ WSDL library which includes a WSDL parser, XML Parser and Serializer,Schema parser and Validator and an API to dynamically inspect and invoke a WSDL web service. C_Sane a C++ wrapper for the SANE library Caches.rb Caches.rb is a simple method caching library. CacheTable CacheTable is a C++ template library that implements a very fast hash map container. CaltrainPy CaltrainPy is a GUI and Python library for Caltrain schedules. It can optionally be used to parse a Caltrain HTML schedule and return it in various machine-friendly formats. There is also a Javascript port available, CaltrainJS, that provides the GUI only. CarvPath CarvPath (libcarvpath) is a library aimed at computer forensic tools that process disk and/or memory dump images or other large data files. CashCow an open source software product for clearing Internet payment transactions with the Danish PBS through an SSL connection Cawfee CGI SDK designed to retrieve the CGI input from the web server and parse it so that programs can use it. CExpert CExpert (Connection Expert) is a simple library that allow high-availability projects to check their mysql base's health. It consists of two parts a daemon and a client library. chilon::parser chilon::parser provides an extended PEG-like language using C++0x template meta-programming. CILib Computational Intelligence Library. A framework for developing CI algorithms such as particle swarms, evolutionary algorithms, neural networks etc CL-EMB a library to embed Common Lisp and special template tags into normal text files. Can be used for dynamically generated HTML pages ConfigFile for Haskell ConfigFile is a configuration file parser and writer library for Haskell. Convex processing Convex processing is a quick and efficient library to perform convex analysis. Some specific fields are addressed, such as general image processing and tomography. Convey Convey is a small UI abstraction layer emphasizing simplicity and speed of development over fine-grained control. It is aimed at utilities and small programs. It uses the end-user's preferred interface library. It supports Motif, GTK 2, and Qt 4. Coronet The coronet library implements an epoll and coroutine based library that allows for async operations over certain kinds of files. Any file that supports poll(2) and the O_NONBLOCK fcntl(2) flag can be hosted; this includes like sockets and pipes. The coronet library uses the epoll support available in the 2.6 series of Linux kernels, and the libpcl library for coroutine support. cprops The c prototyping tools library consists of implementations for several widely used data structures and patterns as well as rudimentary tcp / httpd functionality. Object oriented development environments usually feature readymade implementations of such tools. The libcprops fills in a gap in between the standard c api dating back to the 1970's and functionality needed the times of ubiquitous http services everywhere. Cross-CGI Cross-CGI is a set of three simple, but complete, libraries providing CGI access for C, C++ and Objective C programs. It provides basic header output functions, and parses and decodes form arguments passed back to it. Curie Curie is a very minimalistic, tiny C library. It supports basic I/O, basic networking, S-expression based I/O, signal handling, process handling, and I/O multiplexing. If the target architecture is explicitly supported, statically linked binaries may be as small as 4-20 kilobytes; if not, then it only relies on the host's C library. Dataquay Dataquay is a library that provides a friendly C++ API for the popular Redland RDF data store using Qt4 classes and containers. dbg a set of C++ utilities to facilitate modern debugging idioms. It has been designed to support defensive programming techniques in modern C++ code. It integrates well with standard library usage and has been carefully designed to be easy to write, easy to read and very easy to use dbus-cxx dbus-cxx is yet another dbus C++ wrapper. What differentiates dbus-cxx from other C++ wrappers is that dbus-cxx relies heavily on sigc++ and explicitly exposes the wrapped dbus C API. dbus-tcl dbus-tcl is a Tcl library for interacting with D-Bus.
