# SDL_RenderFillRect

Fill a rectangle on the current rendering target with the drawing color.

## Header File

Defined in [SDL_render.h](https://github.com/libsdl-org/SDL/blob/SDL2/include/SDL_render.h), but apps should _only_ `#include "SDL.h"`!

## Syntax

```c
int SDL_RenderFillRect(SDL_Renderer * renderer,
                       const SDL_Rect * rect);

```

## Function Parameters

|                  |                                                                                                                |
| ---------------- | -------------------------------------------------------------------------------------------------------------- |
| **renderer**     | the rendering context                                                                                          |
| **rect**         | the [SDL_Rect](SDL_Rect) structure representing the rectangle to fill, or NULL for the entire rendering target |

## Return Value

Returns 0 on success or a negative error code on failure; call
[SDL_GetError](SDL_GetError)() for more information.

## Remarks

The current drawing color is set by
[SDL_SetRenderDrawColor](SDL_SetRenderDrawColor)(), and the color's alpha
value is ignored unless blending is enabled with the appropriate call to
[SDL_SetRenderDrawBlendMode](SDL_SetRenderDrawBlendMode)().

## Version

This function is available since SDL 2.0.0.
