====== (This is the documentation for SDL3, which is under heavy development and the API is changing! [https://wiki.libsdl.org/SDL2/ SDL2] is the current stable version!) ====== = SDL_UnregisterApp = Deregister the win32 window class from an [[SDL_RegisterApp]] call. == Syntax == void SDL_UnregisterApp(void); == Remarks == This can be called to undo the effects of [[SDL_RegisterApp]]. Most applications do not need to, and should not, call this directly; SDL will call it when deinitializing the video subsystem. It is safe to call this multiple times, as long as every call is eventually paired with a prior call to [[SDL_RegisterApp]]. The window class will only be deregistered when the registration counter in [[SDL_RegisterApp]] decrements to zero through calls to this function. == Version == This function is available since SDL 3.0.0. ---- [[CategoryAPI]]
