Return whether an explicit rectangle was set as the viewport.

Header File

Defined in <SDL3/SDL_render.h>


SDL_bool SDL_RenderViewportSet(SDL_Renderer *renderer);

Function Parameters

SDL_Renderer * renderer the rendering context.

Return Value

(SDL_bool) Returns SDL_TRUE if the viewport was set to a specific rectangle, or SDL_FALSE if it was set to NULL (the entire target).


This is useful if you're saving and restoring the viewport and want to know whether you should restore a specific rectangle or NULL. Note that the viewport is always reset when changing rendering targets.


This function is available since SDL 3.0.0.
