# SDL_RenderClear

Clear the current rendering target with the drawing color.

## Header File

Defined in [<SDL3/SDL_render.h>](https://github.com/libsdl-org/SDL/blob/main/include/SDL3/SDL_render.h)

## Syntax

```c
bool SDL_RenderClear(SDL_Renderer *renderer);
```

## Function Parameters

|                                |              |                        |
| ------------------------------ | ------------ | ---------------------- |
| [SDL_Renderer](SDL_Renderer) * | **renderer** | the rendering context. |

## Return Value

(bool) Returns true on success or false on failure; call
[SDL_GetError](SDL_GetError)() for more information.

## Remarks

This function clears the entire rendering target, ignoring the viewport and
the clip rectangle. Note, that clearing will also set/fill all pixels of
the rendering target to current renderer draw color, so make sure to invoke
[SDL_SetRenderDrawColor](SDL_SetRenderDrawColor)() when needed.

## Thread Safety

This function should only be called on the main thread.

## Version

This function is available since SDL 3.2.0.
