Function sdl2_sys::SDL_GetError

pub unsafe extern "C" fn SDL_GetError() -> *const c_char

SDL API functions may set error messages and then succeed, so you should only use the error value if a function fails.

This returns a pointer to a static buffer for convenience and should not be called by multiple threads simultaneously.
