Destroying a presentation surface

The presentation surface represents the window of our application. It is used, among other purposes, during swapchain creation. That's why we should destroy the presentation surface after the destruction of a swapchain that is based on a given surface is finished.

How to do it...

1. Prepare the handle of a Vulkan Instance and store it in a variable of type VkInstance named instance.
2. Take the handle of a presentation surface and assign it to the variable of type VkSurfaceKHR named presentation_surface.
3. Call vkDestroySurfaceKHR( instance, presentation_surface, nullptr ) and provide the instance and presentation_surface variables in the first two parameters and a nullptr value in the last parameter.
4. For safety reasons, assign a VK_NULL_HANDLE value to the presentation_surface variable.

How it works...

The presentation surface's destruction is very similar to the destruction of other Vulkan resources presented so far. We make sure we don't provide a VK_NULL_HANDLE value...
