Class KHRWin32Surface

java.lang.Object

org.lwjgl.vulkan.KHRWin32Surface

public class KHRWin32Surface
extends java.lang.Object

The VK_KHR_win32_surface extension is an instance extension. It provides a mechanism to create a VkSurfaceKHR object (defined by the VK_KHR_surface extension) that refers to a Win32 HWND, as well as a query to determine support for rendering to the windows desktop.

nvkCreateWin32SurfaceKHR

public static int nvkCreateWin32SurfaceKHR(org.lwjgl.vulkan.VkInstance instance,
                                           long pCreateInfo,
                                           long pAllocator,
                                           long pSurface)

Unsafe version of: CreateWin32SurfaceKHR

vkCreateWin32SurfaceKHR

public static int vkCreateWin32SurfaceKHR(org.lwjgl.vulkan.VkInstance instance,
                                          VkWin32SurfaceCreateInfoKHR pCreateInfo,
                                          @Nullable
                                          VkAllocationCallbacks pAllocator,
                                          java.nio.LongBuffer pSurface)

Create a VkSurfaceKHR object for an Win32 native window.

C Specification

To create a VkSurfaceKHR object for a Win32 window, call:

 VkResult vkCreateWin32SurfaceKHR(
     VkInstance                                  instance,
     const VkWin32SurfaceCreateInfoKHR*          pCreateInfo,
     const VkAllocationCallbacks*                pAllocator,
     VkSurfaceKHR*                               pSurface);

Valid Usage (Implicit)

• instance must be a valid VkInstance handle
• pCreateInfo must be a valid pointer to a valid VkWin32SurfaceCreateInfoKHR structure
• If pAllocator is not NULL, pAllocator must be a valid pointer to a valid VkAllocationCallbacks structure
• pSurface must be a valid pointer to a VkSurfaceKHR handle

Return Codes

On success, this command returns

• SUCCESS

On failure, this command returns

• ERROR_OUT_OF_HOST_MEMORY
• ERROR_OUT_OF_DEVICE_MEMORY

See Also

VkAllocationCallbacks, VkWin32SurfaceCreateInfoKHR

Parameters:

instance - the instance to associate the surface with.

pCreateInfo - a pointer to a VkWin32SurfaceCreateInfoKHR structure containing parameters affecting the creation of the surface object.

pAllocator - the allocator used for host memory allocated for the surface object when there is no more specific allocator available (see Memory Allocation).

pSurface - a pointer to a VkSurfaceKHR handle in which the created surface object is returned.

vkGetPhysicalDeviceWin32PresentationSupportKHR

public static boolean vkGetPhysicalDeviceWin32PresentationSupportKHR(org.lwjgl.vulkan.VkPhysicalDevice physicalDevice,
                                                                     int queueFamilyIndex)

query queue family support for presentation on a Win32 display.

C Specification

To determine whether a queue family of a physical device supports presentation to the Microsoft Windows desktop, call:

 VkBool32 vkGetPhysicalDeviceWin32PresentationSupportKHR(
     VkPhysicalDevice                            physicalDevice,
     uint32_t                                    queueFamilyIndex);

Description

This platform-specific function can be called prior to creating a surface.

Valid Usage

• queueFamilyIndex must be less than pQueueFamilyPropertyCount returned by vkGetPhysicalDeviceQueueFamilyProperties for the given physicalDevice

Valid Usage (Implicit)

• physicalDevice must be a valid VkPhysicalDevice handle

Parameters:

physicalDevice - the physical device.

queueFamilyIndex - the queue family index.
