+Simple DirectMedia Layer (SDL) is a cross-platform software development library designed to provide a hardware abstraction layer for computer multimedia hardware components. Software developers can use it to write high-performance computer games and other multimedia applications that can run on many operating systems such as Android, iOS, Linux, macOS, and Windows. SDL manages video, audio, input devices, CD-ROM, threads, shared object loading, networking and timers. For 3D graphics, it can handle an OpenGL, Vulkan, Metal, or Direct3D context. The library is internally written in C, and provides the application programming interface in C, with bindings to other languages available. SDL is extensively used in the industry in both large and small projects. Over 700 games, 180 applications, and 120 demos have been posted on the library website.
