NAME

       SDL_RenderPresent - Update the screen with any rendering performed since the previous call.

SYNOPSIS

       #include <SDL3/SDL_render.h>

       bool SDL_RenderPresent(SDL_Renderer *renderer);

DESCRIPTION

       SDL's  rendering  functions  operate  on  a  backbuffer;  that  is,  calling a rendering function such as
       SDL_RenderLine() does not directly put a line on the screen, but rather updates the backbuffer. As  such,
       you compose your entire scene and present the composed backbuffer to the screen as a complete picture.

       Therefore,  when  using  SDL's rendering API, one does all drawing intended for the frame, and then calls
       this function once per frame to present the final drawing to the user.

       The backbuffer should be considered invalidated after each present; do not assume that previous  contents
       will  exist  between  frames.  You  are  strongly  encouraged to call SDL_RenderClear() to initialize the
       backbuffer before starting each new frame's drawing, even if you plan to overwrite every pixel.

       Please note, that in case of rendering to a texture - there is no need to  call  SDL_RenderPresent  after
       drawing  needed  objects  to  a texture, and should not be done; you are only required to change back the
       rendering target to default via SDL_SetRenderTarget(renderer, NULL) afterwards, as textures by themselves
       do not have a concept of backbuffers. Calling SDL_RenderPresent while rendering to a texture  will  still
       update the screen with any current drawing that has been done _to the window itself_.
