#pragma section-numbers off #pragma disable-camelcase = SDL_RenderPresent = Use this function to update the screen with any rendering performed since the previous call. <> == Syntax == {{{#!highlight cpp void SDL_RenderPresent(SDL_Renderer* renderer) }}} == Function Parameters == ||'''renderer'''||the rendering context|| == Code Examples == <> == Remarks == SDL's rendering functions operate on a backbuffer; that is, calling a rendering function such as [[SDL_RenderDrawLine]]() 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. == Related Functions == .[[SDL_RenderClear]] .[[SDL_RenderDrawLine]] .[[SDL_RenderDrawLines]] .[[SDL_RenderDrawPoint]] .[[SDL_RenderDrawPoints]] .[[SDL_RenderDrawRect]] .[[SDL_RenderDrawRects]] .[[SDL_RenderFillRect]] .[[SDL_RenderFillRects]] .[[SDL_SetRenderDrawBlendMode]] .[[SDL_SetRenderDrawColor]] ---- [[CategoryAPI]], [[CategoryRender]]
