Simple DirectMedia Layer (SDL) is a cross-platform multimedia free software library written in C that creates an abstraction over various platforms' graphics, sound, and input APIs, allowing a developer to write a computer game or other multimedia application once and run it on many operating systems including GNU/Linux, Windows and Mac OS X. It manages video, events, digital audio, CD-ROM, sound, threads, shared object loading, networking and timers. SDL Logo. ...

History
Sam Lantinga created the library, first releasing it in early 1998, while working for Loki Software. He got the idea while porting a Windows application to Macintosh. He then used SDL to port Doom to BeOS (see Doom source ports). Several other free libraries appeared to work with SDL, such as SMPEG and OpenAL. Sam Oscar Lantinga is the creator of the Simple DirectMedia Layer which is a very popular open source game programming library. ...

OpenAL (Open Audio Library) is a cross-platform audio API. It is designed for efficient rendering of multichannel three dimensional positional audio. ...
The SDL library has bindings with almost every programming language there is, from the popular (C++, Perl, Python (through pygame), Pascal etc.) to the less known (such as Euphoria or Pliant). This and the fact that it is open-source and licensed under the LGPL make SDL a common choice for many multimedia applications.

SDL itself is very simple; it merely acts as a thin, cross-platform wrapper, providing support for 2D pixel operations, sound, file access, event handling, timing, threading, and more. OpenGL is often used with SDL to provide fast 3D rendering. It is often thought of as a cross-platform DirectX, although it lacks some of its more advanced functionality. SDL instead has a huge number of third party extensions that make it easy to do more advanced functions. OpenGL (Open Graphics Library) is a standard specification defining a cross-language cross-platform API for writing applications that produce 3D computer graphics (and 2D computer graphics as well). ...
DirectX is a collection of APIs for handling tasks related to multimedia, especially game programming, on Microsoft platforms. ...
The library is divided into several subsystems, namely the Video (handles both surface functions and OpenGL), Audio, CD-ROM, Joystick and Timer subsystems. Besides this basic, low-level support, there also are a few separate official libraries that provide some additional functionality. These comprise the "standard library", and are provided on the official website and included in the official documentation: OpenGL (Open Graphics Library) is a standard specification defining a cross-language cross-platform API for writing applications that produce 3D computer graphics (and 2D computer graphics as well). ...
- SDL_image - Is used in conjunction with SDL to provide support for modern image formats. It is maintained by Sam Lantinga and Mattias Engdegård, and is currently able to load the following formats: BMP, PPM, XPM, PCX, GIF, JPEG, PNG, and TGA. This extension is necessary since the main SDL library only provides a way to load and save in the BMP format. Although SDL_image adds support for loading images, there is currently no way of saving images in any other format than the BMP. Besides the core SDL library, SDL_image also needs the IJG, PNG, Zlib and SGI TIFF libraries for loading some of the formats. In the C/C++ binding, SDL_image provides the function
IMG_Load( const char* ) and a few variations all of which return a pointer to a SDL_Surface where the loaded image is stored. - SDL_mixer (complex audio functions, mainly for sound mixing)
- SDL_net (networking support)
- SDL_ttf (TrueType Font rendering support)
- SDL_rtf (simple Rich Text Format rendering).

Architecture
 Abstraction layers of several SDL platforms SDL has the word "layer" in its title because it is actually a wrapper around operating-system-specific functionality. The chief purpose of SDL is to provide a common framework for accessing this functionality. Image File history File links SDL_Layers. ...

Because of the way SDL is designed, a lot of the source code is split into separate modules for each operating system, in order to make calls to the underlying system. When SDL is compiled, the correct modules are selected for the target system.
On Microsoft Windows, SDL actually wraps around DirectX, which in turn wraps around the video driver; SDL is useful for porting to Windows, but merely replicates DirectX functions otherwise. Older versions used DirectX 5, but SDL 1.2 (the current stable release) requires DirectX 7 by default. Sam Lantinga has stated that he plans to use DirectX 8 in future SDL releases[1]. Microsoft Windows is the name of several families of proprietary software operating systems by Microsoft. ...

Syntax and subsystems -
The syntax of SDL is function-based, all operations done in SDL are done by passing parameters to functions. Special structures are also used to store the specific information SDL needs to handle. There are a few different subsystems SDL categorizes its functions under: The syntax of Simple DirectMedia Layer (SDL) is a set of rules and functions that allow one to use the library. ...

Example Code (C) // Headers #include "SDL.h" // Main function int main( int argc, char* argv[] ) { // Initialize SDL if( SDL_Init( SDL_INIT_EVERYTHING ) == -1 ) return( 1 ); // Delay 2 seconds SDL_Delay( 2000 ); // Quit SDL SDL_Quit(); // Return return( 0 ); } A very basic SDL program. It loads SDL subsystems, pauses for 2 seconds, closes SDL, then exits the program.
