# SDL_SetWindowBordered

Set the border state of a window.

## Header File

Defined in [SDL_video.h](https://github.com/libsdl-org/SDL/blob/SDL2/include/SDL_video.h)

## Syntax

```c
void SDL_SetWindowBordered(SDL_Window * window,
                           SDL_bool bordered);
```

## Function Parameters

|                            |              |                                                                              |
| -------------------------- | ------------ | ---------------------------------------------------------------------------- |
| [SDL_Window](SDL_Window) * | **window**   | the window of which to change the border state.                              |
| [SDL_bool](SDL_bool)       | **bordered** | [SDL_FALSE](SDL_FALSE) to remove border, [SDL_TRUE](SDL_TRUE) to add border. |

## Remarks

This will add or remove the window's
[`SDL_WINDOW_BORDERLESS`](SDL_WINDOW_BORDERLESS) flag and add or remove the
border from the actual window. This is a no-op if the window's border
already matches the requested state.

You can't change the border state of a fullscreen window.

## Version

This function is available since SDL 2.0.0.
