| SDL_RenderViewportSet(3) | SDL3 FUNCTIONS | SDL_RenderViewportSet(3) |
SDL_RenderViewportSet - Return whether an explicit rectangle was set as the viewport.
Defined in SDL3/SDL_render.h
#include "SDL3/SDL.h"
bool SDL_RenderViewportSet(SDL_Renderer *renderer);
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.
Each render target has its own viewport. This function checks the viewport for the current render target.
Returns true if the viewport was set to a specific rectangle, or false if it was set to NULL (the entire target).
This function should only be called on the main thread.
This function is available since SDL 3.2.0.
