Usage
#include "SDL3/SDL.h"
bool SDL_FillSurfaceRect(SDL_Surface *dst, const SDL_Rect *rect, Uint32 color);
Header file
Defined in SDL3/SDL_surface.h
Overview
color should be a pixel of the format used by the surface, and can be generated by SDL_MapRGB () or SDL_MapRGBA (). If the color value contains an alpha component then the destination is simply filled with that alpha information, no blending takes place.
If there is a clip rectangle set on the destination (set via
SDL_SetSurfaceClipRect ()), then this function will fill based on the intersection of the clip rectangle and rect .
