especially SDL_VIDEODRIVER is commonly used to use the native Wayland backend, so I think it's a good idea to keep supporting the old name instead of forcing users to find out that they now have to add an underscore.. Not sure how popular SDL_AUDIODRIVER is, but with all the audio backends that exist on Linux alone I'm sure some people use it to work around sound issues. Note: Doing this in the SDL_hints implementation instead of the call-sites of SDL_GetHint(SDL_HINT_VIDEO_DRIVER) etc ensures that 1. Hint priorities work (env var overriding hint set by application with normal priority, but not when application used SDL_HINT_OVERRIDE) 2. SDL_ResetHint() (called by user code) respects the fallback environment variable
Simple DirectMedia Layer
Simple DirectMedia Layer is a cross-platform development library designed to provide low level access to audio, keyboard, mouse, joystick, and graphics hardware. 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, macOS, 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.
This library is distributed under the zlib license, which can be found in the file "LICENSE.txt".
Information on building SDL with CMake is available in README-cmake.md
The best way to learn how to use SDL is to check out the header files in the "include" subdirectory and the programs in the "test" subdirectory. The header files and test programs are well commented and always up to date.
Information on reporting bugs and contributing is available in README-contributing.md
More documentation and FAQs are available online at the wiki
