Free c language library software for linux

GNU C library (glibc) is one of the most important components of GNU Hurd and most modern Linux distributions.

GNU C library is used by almost all C programs and provides the most essential program interface.

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.

The GNU C library is primarily designed to be a portable and high performance C library.

It follows all relevant standards (ISO C 99, POSIX.1c, POSIX.1j, POSIX.1d, Unix98, Single Unix Specification). It is also internationalized and has one of the most complete internationalization interfaces known.

CVS Perl library is a Perl module which is a wrapper around the CVS command with an object-oriented interface.

Installation:

To install this module type the following:

perl Makefile.PL
make
make test
make install

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.
The C Programming Language has a much smaller standard library compared to other more modern programming languages such as Java or Python.
In particular, it lacks implementations of many common data structures and algorithms. This is a collection of such algorithms to attempt to alleviate this problem.
The source code is released under the Modified BSD license, and as such can be freely modified and reused in any project, either proprietary or free. It is written in 100% ANSI standard C.
Each algorithm is written to be independent from the other implementations, allowing particular algorithms to be included in projects as needed.
Data structures
Collections
ArrayList : Automatically resizing array.
Doubly linked list : A set of values stored in a list with links that point in both directions.
Singly linked list : A set of values stored in a list with links that point in one direction.
Queue : Double ended queue which can be used as a FIFO or a stack.
Set : Unordered set of values.
Mappings
Hash table : Collection of values which can be addressed using a key.
Trie : Fast mapping using strings as keys.
Binary search trees
AVL tree : Balanced binary search tree with O(log n) worst case performance.
Utility functions
All of the above data structures operate on void pointers. It is sometimes necessary to compare values (when sorting a list, for example) or generate a hash key (in a hash table or set). This is done by providing a pointer to a function which provides this functionality. The following functions provide this functionality for some common data types.
- Integer comparison and hash functions.
- String comparison and hash functions.
- Generic (void) pointer comparison and hash functions.

Zild Database Library implements a small and easy to use database API with an easy to use API.
Main features:
- ability to connect to multiple database systems
- zero runtime configuration
- ability to connect using a URL scheme
- thread-safe connection pooling.

The Complex Language project is an object oriented programming language intended for scripting or rapid prototyping of applications.
The design goals were to have very few simple but powerful concepts and to be easy to use and easy to learn. The project provides a working interpreter along with a complete specification of the language.
Enhancements:
- This is the first release of the specification and the corresponding interpreter.
- The corresponding library is very poor, and there are probably still bugs in the interpreter.

mfGraph is a graph rendering library for interactive applications. Written in C++ and Python, mfGraph parses GraphViz DOT and XDOT files and provides rendering and hit-testing facilities. Supports Microsoft Windows natively, GNU/Linux through wxPython.
Main features:
- An object model for manipulating graphs and their attributes
- As a serialization format, the GraphViz DOT language is used
- The DOT tool can be used to calculate the layout, then mfGraph is used to build a list of primitive drawing commands by interpreting the XDOT attributes
- For each platform, all that is needed are basic drawing functions (text, lines, ellipses, Bezier curves, and the like) to do the actual rendering
- Zooming and hit-testing are supported
Enhancements:
- Added Visual Studio 2005 project files (".vcproj", ".sln")
- Minor code fixes to resolve compiler errors and warnings in Visual Studio 2005

Redland RDF library is a set of free software packages that provide support for the Resource Description Framework (RDF).
Main features:
- Modular, object based libraries written in C.
- APIs for manipulating the RDF graph, triples, URIs and Literals.
- Triple sequences for efficient streaming.
- Parsers and Serializers for reading and writing RDF as RDF/XML, N-Triples and Turtle Terse RDF Triple Language syntaxes via the Raptor RDF Parser Toolkit.
- Storage for graphs in memory, with Sleepycat/Berkeley DB, MySQL 3/4, AKT Triplestore, SQLite, files or URIs.
- Querying with RDQL and SPARQL using the Rasqal RDF Query Library.
- Redland contexts for managing data aggregation and recording provenance.
- Language Bindings in C#, Java, Obj-C, Perl, PHP, Python, Ruby and Tcl via the Redland Bindings package.
- Command line utility programs rdfproc (RDF), rapper (parsing) and roqet (query).
- Portable, fast and with no known memory leaks.
Enhancements:
- The code was updated to use Rasqal RDF query library 0.9.14 and Raptor RDF parser/serializer library 1.4.15.
- A new transaction API was added, implemented with MySQL for consistent changes to the graph.
- A new query results formatter class was added.
- Many other bugs were fixed.
