mimetic A free/GPL C++ MIME Library

mimetic is a free/GPL Email library (MIME) written in C++ designed to be easy to use and integrate but yet fast and efficient. It is based on the C++ standard library and heavily uses templates so require standard compliant C++ compilers. It has been developed using GCC 3.x and tested on most Unixes. mimetic code include some classes that are not strictly needed but are there just to improve performance. Most classes functionalities and behavior will be clear if you ever studied MIME and its components; if you don’t know anything about Internet messages you’ll probably want to read some RFCs to understand the topic and, therefore, easily use the library whose names, whenever possible, overlap terms adopted in the standard RFC documents. At the very least: RFC 822, RFC 2045 and RFC 2046. A more complete list can be found at the Earl Wood’s MIME page.

SNMP C++ Library, MIB Compiler and SNMP Testing Tools

These are commercial products. The SNMP Builder for C++ has two different packages, supporting Windows 2003/2000/XP operating systems:

• SNMP Builder for Microsoft VC++ v6 and .NET 2003, 2005.

• SNMP Builder for Borland C++ Builder v6 and Studio 2006.

Both SNMP Builder packages include:

• SNMP C++ Class Library v3.3 supporting SNMP v2c and v1.

• Guide and Reference Manual.

• Examples.

The MIB Compiler with a friendly and flexible graphic user interface allows the quick and easy accomplishment of the MIB compilation process. A programmer can determine the correct order of MIBs to compile in a matter of seconds using powerful built-in error processing and file search facilities. The final step of the MIB compilation process is generation of C++ header files with MIB object definitions. The MIB Compiler enables SNMP object references to use symbolic names. This makes programming easier and simplifies the software maintenance and modification process. New, efficient, easy to use and versatile methods have been added to make software development even easier and more pleasant. As with the SNMP Toolkit, the SNMP Builder comes with two very useful SNMP tools:

• An SNMP Sender and

• An SNMP Tracer.

These two GUI utilities provide a much more precise and flexible interface (comparing to MIB browser) assisting in debugging of SNMP software and also in studying how the existing SNMP software works in real life applications. The Tracer utility replaces the need for a very expensive protocol analyzers. It can display both parsed SNMP message fields (SNMP message header, PDU fields and variable binding list details) and raw message data. The trace can be saved and printed. The utility can receive on standard SNMP ports: 161 and 162, and also on non-standard ports. The Sender utility includes a graphic editor enabling the creation of SNMP request messages with precise control of message type, header fields and variable binding list. The utility can send the requests to a specified destination, displaying the details about sent requests and received replies. The sender can send the same request multiple times to a single destination, measuring network performance and the maximum number of requests an agent can process per second. These requests can be saved and then used later on during regression testing. The detailed programming guide and reference manual in Adobe Acrobat format contains hyperlinks which simplify the quick reference look-up and serves as an on-line help. The extensive programming guide illustrates all the aspects, features and pitfalls of using class library objects, methods and properties to achieve maximum performance, reliability and flexibility of the software being developed.

Synapse project – blocking (synchronous) sockets network communication

This project deals with network communication by means of blocking (synchronous) sockets or with limited non-blocking mode. This project not using asynchronous sockets. The Project contains simple low level non-visual objects for easiest programming without problems (no need multithread synchronization, no need for windows message processing…) Great for command line utilities, visual projects, NT services… You can find more after reading about and features. This project is freeware and open source under modified BSD style license.

The SYNAPSE library aims to create a complete library of classes and functions that would markedly simplify application programming of network communication using Winsock. At first glance this effort might seem needless as there are many free components covering this area, however they mostly use asynchronous methods while SYNAPSE library operates in a synchronous method.

Synchronous mode (called ‘blocking’ in Winsock terminology) features acting thread waits until the needed operation terminates. Thus when we want to send data, the program exits function only after data is sent – or – if we want to receive data, the program exits the function only after the desired data is received. Thus, much more crisp and simple programming is achieved. You will feel it when trying to implement any Internet protocol, which is typically based on ‘send-wait for reply’ method. If you want to implement it in an asynchronous method, you would have to accept complicated event processing and synchronous mode simulation. Therefore a synchronous socket is simple and natural for the majority programming tasks. The whole library is oriented on the WIN32 environment or Linux environment, so you will need Delphi 3.0 or higher and Kylix 1.0 or higher to use it

DataReel – cross-platform database and communications toolkit

By using DataReel you can extend the power of the C++ programming language by using high-level programming interfaces for database, communications, and multi-threaded programming…”

Sound Processing Kit – SPKit, a C++ object-oriented class library for audio signal processing

Sound Processing Kit is an object-oriented class library for audio signal processing. Sound Processing Kit (abbreviated as SPKit) includes classes for various signal processing tasks, but most importantly, it introduces a way of implementing sound processing algorithms in a simple object-oriented manner. Sound Processing Kit is implemented in C++.

SPKit is designed to be portable. The current version requires a bare-bones C++ 2.0 compatible compiler (templates and exceptions are not needed). ANSI C standard libraries are required. The source code should compile with little or no modification on most UNIX compatible platforms.

There are three versions of the SPKit class library: a “generic” version, a libaudiofile version, and an SGI version. The generic version is the most portable one and does not require extra libraries audio file I/O. On the other hand, the number of supported sound file formats is very limited. The libaudiofile version requires the Audio File Library system for file I/O. Audio File Library is with many Linux distributions and has been ported to other operating systems as well. The home page of Audio File Library is at audio files. The SGI version is written specifically for the SGI/IRIX system.

Free C++ Signal and Image Processing Library

The C++ Free Signal and Image Processing Library is a free collection of general-purpose, optimized C++ routines and classes for signal and image processing along with utility classes to aid image and video file manipulation.

OptiVec – vector, matrix functions and complex-number math routines

OptiVec is a complete, hand-optimized set of libraries with over 3500 vector and matrix functions, and complex-number math routines. It contains the fully vectorized forms of all operators and math functions of C/C++/Pascal/Delphi for all integer and floating-point (including complex) data types, plus many other real and complex math functions and routines for statistics, analysis, FFT techniques, curve fitting, interpolations, vector and matrix algebra, matrix decomposition, and graphics. In parts, OptiVec overlaps with the well-known BLAS and LINPACK libraries, but features an easier nomenclature and a generally more efficient implementation. It consists of three groups of functions:

• VectorLib – Vector functions.

• MatrixLib – Matrix functions.

• CMATH – Complex number math functions (also available separately).

The OptiVec libraries are static, no DLLs. This means only those functions which you actually need are linked into your application. Of course, you are free to include OptiVec functions in your DLLs, but there is no need to deal with yet another set of DLLs when you distribute your applications. Once you purchase the Commercial Edition of OptiVec, you can freely distribute applications containing OptiVec functions. No run-time licenses needed for your customers. An Educational Edition is available at a strongly reduced fee for non-commercial use. The target Compilers include:

• Embarcadero (former Borland and CodeGear) C/C++ compiler series (RAD Studio, Borland Development Suite, BC++ Builder 1-6, BC++ 4.0 or higher, Turbo C++)

• Microsoft Visual C++ (5, 6, up to Visual Studio 2010).

• Borland Delphi (4 through 7, 2005, 2006, 2007, 2009, 2010, XE, XE2, Turbo Delphi, RAD Studio).
