(This is the documentation for SDL3, which is the current stable version. SDL2 was the previous version!)

Remarks

This function clears the entire rendering target, ignoring the viewport and the clip rectangle. Note, that clearing will also set/fill all pixels of the rendering target to current renderer draw color, so make sure to invoke SDL_SetRenderDrawColor() when needed.
