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 extending structures to the pNext chain of its pSurfaceCapabilities parameter.

Valid Usage
  • surface must be a valid VkSurfaceKHR handle
  • surface must be supported by physicalDevice, as reported by GetPhysicalDeviceSurfaceSupportKHR or an equivalent platform-specific mechanism
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
On failure, this command returns

Parameters
physicalDevice:VkPhysicalDevice

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

surface:long

the surface that will be associated with the swapchain.

pSurfaceCapabilities:VkSurfaceCapabilities2EXT

a pointer to a VkSurfaceCapabilities2EXT structure in which the capabilities are returned.
