public class EXTDisplaySurfaceCounter
extends java.lang.Object

This is extension defines a vertical blanking period counter associated with display surfaces. It provides a mechanism to query support for such a counter from a VkSurfaceKHR object.

Method Detail

nvkGetPhysicalDeviceSurfaceCapabilities2EXT

public static int nvkGetPhysicalDeviceSurfaceCapabilities2EXT(VkPhysicalDevice physicalDevice,
                                                              long surface,
                                                              long pSurfaceCapabilities)

Unsafe version of: GetPhysicalDeviceSurfaceCapabilities2EXT

vkGetPhysicalDeviceSurfaceCapabilities2EXT

public static int vkGetPhysicalDeviceSurfaceCapabilities2EXT(VkPhysicalDevice physicalDevice,
                                                             long surface,
                                                             VkSurfaceCapabilities2EXT pSurfaceCapabilities)

Query surface capabilities.

C Specification

To query the basic capabilities of a surface, needed in order to create a swapchain, call:

 VkResult vkGetPhysicalDeviceSurfaceCapabilities2EXT(
     VkPhysicalDevice                            physicalDevice,
     VkSurfaceKHR                                surface,
     VkSurfaceCapabilities2EXT*                  pSurfaceCapabilities);

Description

vkGetPhysicalDeviceSurfaceCapabilities2EXT behaves similarly to GetPhysicalDeviceSurfaceCapabilitiesKHR, with the ability to return extended information by adding extension structures to the pNext chain of its pSurfaceCapabilities parameter.

Valid Usage (Implicit)

• physicalDevice must be a valid VkPhysicalDevice handle
• surface must be a valid VkSurfaceKHR handle
• pSurfaceCapabilities must be a valid pointer to a VkSurfaceCapabilities2EXT structure
• Both of physicalDevice, and surface must have been created, allocated, or retrieved from the same VkInstance

Return Codes

On success, this command returns

• SUCCESS

On failure, this command returns

• ERROR_OUT_OF_HOST_MEMORY
• ERROR_OUT_OF_DEVICE_MEMORY
• ERROR_SURFACE_LOST_KHR

Parameters:

physicalDevice - the physical device that will be associated with the swapchain to be created, as described for CreateSwapchainKHR.

surface - the surface that will be associated with the swapchain.

pSurfaceCapabilities - a pointer to an instance of the VkSurfaceCapabilities2EXT structure in which the capabilities are returned.
