Free c api libraries software for linux

LBC Libraries is a set of easy C libraries that provide classical data types and structures (string, hash, queue, stack, tree).
LBC Libraries package is focused on simplicity and portability. It uses ANSI C (C98 standard not required), and provides the most generic approach possible so that queues can have items of different types, hashes can have keys of different data types, trees can be binary trees or have arbitrary numbers of branches, etc.
Enhancements:
- This release adds minor API changes, enhances the documentation, and fixes major bugs in LBCstring.

DAEMon Raco Libraries (DRLibs) is a collection of useful functions, objects, and routines for C++.
Enhancements:
- This release adds new libraries to manage object lists: doublelist.dr.h, simplelist.dr.h, and sortedlist.dr.h.

The Adobe Source Libraries (ASL) are a collection of C++ libraries building foundation technology to allow the construction of commercial applications by assembling generic algorithms through declarative descriptions.
Enhancements:
- GIL version 2.1 (support for sub-byte aligned pixel values in images).
- An ASL version_0 namespace has been introduced to maintain binary compatibility going forward.
- There are poly< > library improvements. adobe/vector.hpp and adobe/closed_hash.hpp have been added as generic containers.
- There are many other improvements.

Gnome Devtool Libraries project contains components and libraries that are intended to be shared between GNOME development tools, including gnome-debug,
gnome-build, and anjuta2.

The current pieces of GDL include:

- A symbol browser bonobo component (symbol-browser-control).

- A docking widget (gdl).

- A utility library that also contains the stubs and skels for the symbol browser and text editor components (gdl, idl).

Discussion of GDL development takes place on the gnome-devtools@gnome.org
mailing list and on #devel-apps at irc.gnome.org.

GDL is licensed under the terms of the GPL.

Installation:

The simplest way to compile this package is:

1. `cd to the directory containing the packages source code and type `./configure to configure the package for your system. If youre using `csh on an old version of System V, you might need to type `sh ./configure instead to prevent `csh from trying to execute `configure itself.

Running `configure takes awhile. While running, it prints some messages telling which features it is checking for.

2. Type `make to compile the package.

3. Optionally, type `make check to run any self-tests that come with the package.

4. Type `make install to install the programs and any data files and documentation.

5. You can remove the program binaries and object files from the source code directory by typing `make clean. To also remove the files that `configure created (so you can compile the package for a different kind of computer), type `make distclean. There is also a `make maintainer-clean target, but that is intended mainly for the packages developers. If you use it, you may have to get all sorts of other programs in order to regenerate files that came with the distribution.

Ham Radio Control Libraries is a development effort to provide a consistent interface for programmers wanting to incorporate radio control in their programs.

Hamlib is not a complete user application, rather, it is a software layer intended to make controlling various radios and other shack hardware much easier.

Hamlib will allow authors of such software as logging programs, digital communications programs, or those wanting to develop the ultimate radio control software to concentrate on the user interface and the basic function of the program rather than radio control.

Most recent amateur radio transceivers allow external control of their functions through a serial interface. Unfortunately, control commands are not always consistent across a manufacturers product line and each manufacturers product line differs greatly from its competitors.

Hamlib attempts to solve this problem by presenting a "virtual radio" to the programmer by providing an API to actions such as setting a given VFOs frequency, setting the operating mode, querying the radio of its current status and settings, and giving the application a list of a given radios capabilities. Unfortunately, what can be accomplished by hamlib is limited by the radios themselves and some offer very limited capability.

Mesa is a 3-D graphics library with an API which is very similar to that of OpenGL. To the extent that Mesa utilizes the OpenGL command syntax or state machine, it is being used with authorization from Silicon Graphics, Inc.(SGI). However, the author does not possess an OpenGL license from SGI, and makes no claim that Mesa is in any way a compatible replacement for OpenGL or associated with SGI. Those who want a licensed implementation of OpenGL should contact a licensed vendor.
Please do not refer to the library as MesaGL (for legal reasons). Its just Mesa or The Mesa 3-D graphics libraryand thats all.

Courier Authentication Library is an API toolkit for implementing password validation and account metadata lookups. Copies of this library code used to exist in other tarballs: Courier, Courier-IMAP, and SqWebMail. Building and installing any of these packages wouldve automatically installed this authentication code.
The authentication library is now a separate, standalone package. This authentication library must now be installed, separately, before upgrading to the following builds (or if installing them for the first time): Courier 0.48, Courier-IMAP 4.0, and SqWebMail 5.0.
The Courier authentication library provides authentication services for other Courier applications. In this context, the term "authentication" refers to the following functions:
1. Take a userid or a loginid, and a password. Determine whether the loginid and the password are valid.
2. Given a userid, obtain the following information about the userid:
A. The accounts home directory.
B. The numeric system userid and groupid that owns all files associated with this account.
C. The location of the accounts maildir.
D. Any maildir quota defined for this account. See the Courier documentation for more information on maildir quotas.
E. Other miscellaneous account-specific options.
3. Change the password associated with a loginid.
4. Obain a complete list of all loginids.
The Courier authentication library provides alternative implementations of these authentication services:
1. Use the traditional system password files: /etc/passwd and /etc/shadow, possibly in conjunction with the PAM library.
2. Maintain all this information in a GDBM or a DB database. The GDBM or the DB database is compiled from plain text files. Perl scripts provide a simple interface for creating and editing the authentication information, then a script compiles the plain text files into a database.
3. Use an LDAP server for authentication.
4. Use a table in a MySQL database for authentication.
5. Use a table in a PostgreSQL database for authentication.
All Courier components that use this authentication library, therefore, will be able to authenticate E-mail accounts using any of the above methods.
Enhancements:
- This release fixes many compiler warnings, updates the LDAP API to OpenLDAP 2.3, tweaks the Makefile to make Solariss linker happy, and cleans up the RPM spec file.

FFI::Library is a module with Perl Access to Dynamically Loaded Libraries.

SYNOPSIS

use FFI::Library;
$lib = FFI::Library->new("mylib");
$fn = $lib->function("fn", "signature");
$ret = $fn->(...);

This module provides access from Perl to functions exported from dynamically linked libraries. Functions are described by signatures, for details of which see the FFI modules documentation.

EXAMPLES

$clib_file = ($^O eq "MSWin32") ? "MSVCRT40.DLL" : "-lc";
$clib = FFI::Library->new($clib_file);
$strlen = $clib->function("strlen", "cIp");
$n = $strlen->($my_string);
