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.
SDL has the word "layer" in its title because it is actually a wrapper around operating-system-specific functions. The main purpose of SDL is to provide a common framework for accessing these functions. For further functionality beyond this goal, many libraries have been created to work on top of SDL.
Software developers use it to write computer games and other multimedia applications that can run on many operating systems including Android, AmigaOS, AmigaOS 4, FreeBSD, BeOS/Haiku, iOS, Linux, Mac OS 9, Mac OS X, MorphOS, OpenVMS, PlayStation Portable, Syllable, Symbian, webOS, and Windows. It manages video, events, digital audio, CD-ROM, threads, shared object loading, networking and timers.

Famous quotes containing the words simple and/or layer:
“At present the globe goes with a shattered constitution in its orbit.... No doubt the simple powers of nature, properly directed by man, would make it healthy and a paradise; as the laws of man’s own constitution but wait to be obeyed, to restore him to health and happiness.”
—Henry David Thoreau (1817–1862)
“A revolution is not the overturning of a cart, a reshuffling in the cards of state. It is a process, a swelling, a new growth in the race. If it is real, not simply a trauma, it is another ring in the tree of history, layer upon layer of invisible tissue composing the evidence of a circle.”
—Kate Millett (b. 1934)
