NAME

       SDL_SetRenderViewport - Set the drawing area for rendering on the current target.

HEADER FILE

       Defined in SDL3/SDL_render.h

SYNOPSIS

       #include "SDL3/SDL.h"

       bool SDL_SetRenderViewport(SDL_Renderer *renderer, const SDL_Rect *rect);

DESCRIPTION

       Drawing will clip to this area (separately from any clipping done with

       SDL_SetRenderClipRect  ),  and  the top left of the area will become coordinate (0, 0) for future drawing
       commands.

       The area's width and height must be >= 0.

       Each render target has its own viewport. This function sets the viewport for the current render target.

FUNCTION PARAMETERS

       renderer
              the rendering context.

       rect   the SDL_Rect
               structure representing the drawing area, or NULL to set the viewport to the entire target.

RETURN VALUE

       Returns true on success or false on failure; call

       SDL_GetError () for more information.

THREAD SAFETY

       This function should only be called on the main thread.

AVAILABILITY

       This function is available since SDL 3.2.0.
