# SDL_Vulkan_DestroySurface

Destroy the Vulkan rendering surface of a window.

## Header File

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

## Syntax

```c
void SDL_Vulkan_DestroySurface(VkInstance instance,
                           VkSurfaceKHR surface,
                           const struct VkAllocationCallbacks *allocator);
```

## Function Parameters

|                                      |               |                                                                                                              |
| ------------------------------------ | ------------- | ------------------------------------------------------------------------------------------------------------ |
| VkInstance                           | **instance**  | the Vulkan instance handle.                                                                                  |
| VkSurfaceKHR                         | **surface**   | vkSurfaceKHR handle to destroy.                                                                              |
| const struct VkAllocationCallbacks * | **allocator** | a VkAllocationCallbacks struct, which lets the app set the allocator that destroys the surface. Can be NULL. |

## Remarks

This should be called before [SDL_DestroyWindow](SDL_DestroyWindow), if
[SDL_Vulkan_CreateSurface](SDL_Vulkan_CreateSurface) was called after
[SDL_CreateWindow](SDL_CreateWindow).

The `instance` must have been created with extensions returned by
[SDL_Vulkan_GetInstanceExtensions](SDL_Vulkan_GetInstanceExtensions)()
enabled and `surface` must have been created successfully by an
[SDL_Vulkan_CreateSurface](SDL_Vulkan_CreateSurface)() call.

If `allocator` is NULL, Vulkan will use the system default allocator. This
argument is passed directly to Vulkan and isn't used by SDL itself.

## Version

This function is available since SDL 3.1.3.
