###### (This is the documentation for SDL3, which is under heavy development and the API is changing! [SDL2](https://wiki.libsdl.org/SDL2/) is the current stable version!) # SDL_FillSurfaceRect Perform a fast fill of a rectangle with a specific color. ## Header File Defined in [SDL_surface.h](https://github.com/libsdl-org/SDL/blob/main/include/SDL3/SDL_surface.h), but apps should use `#include ` ## Syntax ```c int SDL_FillSurfaceRect(SDL_Surface *dst, const SDL_Rect *rect, Uint32 color); ``` ## Function Parameters | | | | ------------- | --------------------------------------------------------------------------------------------------------- | | **dst** | the [SDL_Surface](SDL_Surface) structure that is the drawing target | | **rect** | the [SDL_Rect](SDL_Rect) structure representing the rectangle to fill, or NULL to fill the entire surface | | **color** | the color to fill with | ## Return Value Returns 0 on success or a negative error code on failure; call [SDL_GetError](SDL_GetError)() for more information. ## Remarks `color` should be a pixel of the format used by the surface, and can be generated by [SDL_MapRGB](SDL_MapRGB)() or [SDL_MapRGBA](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](SDL_SetSurfaceClipRect)()), then this function will fill based on the intersection of the clip rectangle and `rect`. ## Version This function is available since SDL 3.0.0. ## See Also * [SDL_FillSurfaceRects](SDL_FillSurfaceRects) ---- [CategoryAPI](CategoryAPI), [CategoryAPIFunction](CategoryAPIFunction)
