###### (This is the legacy documentation for stable SDL2, the current stable version; [SDL3](https://wiki.libsdl.org/SDL3/) is the current development version.) # SDL_FillRect Perform a fast fill of a rectangle with a specific color. ## Syntax ```c int SDL_FillRect (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_SetClipRect](SDL_SetClipRect)()), then this function will fill based on the intersection of the clip rectangle and `rect`. ## Version This function is available since SDL 2.0.0. ## Related Functions * [SDL_FillRects](SDL_FillRects) ---- [CategoryAPI](CategoryAPI)
