Bug 1882

Summary: SDL_GetKeyboardState should return const.

Description Yuri K. Schlesner 2013-05-31 22:16:20 UTC 
The array returned by SDL_GetKeyboardState is also used internally by SDL to keep track of pressed/released keys and must not be modified, lest weird behaviour occurs. Because of this I believe it's return type should be changed to return a const pointer, which will provide a code indication of that fact. This can cause existing code to stop compiling, so before a stable release of SDL 2 is the ideal moment to do a change like this.

Failing that, the wiki docs should at least mention this.

Agreed.  Good catch!
