Simple DirectMedia Layer (SDL) is a cross-platform, free and open source multimedia library. Should not be confused with Security Development Lifecycle.

Simple DirectMedia Layer (SDL) is a cross-platform, free and open source multimedia library written in C that presents a simple interface to various platforms' graphics, sound, and input devices.

From SDL's home page:

Simple DirectMedia Layer is a cross-platform development library designed to provide low level access to audio, keyboard, mouse, joystick, and graphics hardware via OpenGL and Direct3D. It is used by video playback software, emulators, and popular games including Valve's award winning catalog and many Humble Bundle games.

SDL officially supports Windows, Mac OS X, Linux, iOS, and Android. Support for other platforms may be found in the source code.

SDL is written in C, works natively with C++, and there are bindings available for several other languages, including C# and Python.

SDL 2.0 is distributed under the zlib license. This license allows you to use SDL freely in any software.
