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.

Y std_utils std_utils features a strip() function (to strip STL string from leading/trailing chars), a gettok() function (gets tokens from a STL string) and a cLog class (performs logs to a file without risk of losing data on program crash). STL AVL Map This is a fully STL-compliant C++ map/set/multimap/multiset implementation for g++ using an AVL tree instead of a Red-Black tree (that is present in libstdc++). It currently works only with g++ 3.4. Str a generic string library written in ANSI C which provides functions for handling, matching, parsing, searching and formatting of C strings. So it can be considered as a superset of POSIX string(3), but its main intention is to provide a more convinient and compact API plus a more generalized functionality STX B+ Tree The STX B+ Tree package is a set of C++ template classes implementing a B+ tree key/data container in main memory. The classes are designed as drop-in replacements of the STL containers set, map, multiset, and multimap, and follow their interfaces very closely. By packing multiple value pairs into each node of the tree, the B+ tree reduces heap fragmentation and utilizes cache-line effects better than the standard red-black binary tree. The tree algorithms are based on the implementation in Cormen, Leiserson, and Rivest's Introduction into Algorithms, Jan Jannink's paper, and other algorithm resources. The classes contain extensive assertion and verification mechanisms to ensure the implementation's correctness by testing the tree invariants.

These modules include Splay and AVL trees, Sparse Arrays, a simple caching system, and the obligatory linked lists ucommon UCommon is a lightweight C++ library to facilitate using C++ design patterns even for very deeply embedded applications, such as for systems using uClibc along with POSIX threading support. For this reason, UCommon disables language features that consume memory or introduce runtime overhead. UCommon introduces some design patterns from Objective-C, such as reference counted objects, memory pools, and smart pointers. UCommon introduces some new concepts for handling of thread locking and synchronization. UltraText UltraText is an MFC-like UI framework for development of interactive terminal applications with a TurboVision look. Units of measurement for Ada The library provides an implementation of dimensioned values for Ada. Unit checks are made at run-time, if not optimized out by the compiler. SI and irregular measurement units are supported. Shifted units like degrees Celsius are supported too. Conversions from and back to strings are provided for all various irregular units. Universal Parallel Port I/O library Universal Parallel Port I/O library exposes a common API for real mode and permission-restricted access to parallel port under Windows, Linux, and MS-DOS operating systems. It also allows pin-by-pin port access. Useful Terminal I/O Library This Useful Terminal IO library is a C++ alternative to ncurses for working with terminfo-defined terminals. Included are raw terminfo string access and output, an efficient buffered output system, and a keyboard driver.

Wiggly-Log Wiggly-Log is a small C++ logging library. It provides procedural and streams interfaces, as well as macros to allow you to remove logging at compile time. The goal is to eliminate logging overhead to easily improve speed in time-sensitive code. wimpiggy Wimpiggy is a library for writing EWMH-compliant, compositing window managers using Python and GTK+.

It relies on no platform-specific or compiler-specific constructs and doesn't require pre-processing of your source code by scripting languages or use macros to create secret classes that use Schwarz counters to register test cases. It relies on you to simply code what you want, and nothing that you don't want. yatesParse yatesParse is a C++ library for parsing and handling command line arguments.
