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 (SDL) Version 3.0
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.
More extensive documentation is available in the docs directory, starting with README.md. If you are migrating to SDL 3.0 from SDL 2.0, the changes are extensively documented in README-migration.md.
Enjoy!
