C Specification

An application queries if a protected VkSurfaceKHR is displayable on a specific windowing system using VkSurfaceProtectedCapabilitiesKHR, which can be passed in pNext parameter of VkSurfaceCapabilities2KHR.

The VkSurfaceProtectedCapabilitiesKHR structure is defined as:

// Provided by VK_KHR_surface_protected_capabilities
typedef struct VkSurfaceProtectedCapabilitiesKHR {
VkStructureType    sType;
const void*        pNext;
VkBool32           supportsProtected;
} VkSurfaceProtectedCapabilitiesKHR;

Members

• sType is the type of this structure.

• pNext is NULL or a pointer to a structure extending this structure.

• supportsProtected specifies whether a protected swapchain created from VkPhysicalDeviceSurfaceInfo2KHR::surface for a particular windowing system can be displayed on screen or not. If supportsProtected is VK_TRUE, then creation of swapchains with the VK_SWAPCHAIN_CREATE_PROTECTED_BIT_KHR flag set must be supported for surface.

Description

If the VK_GOOGLE_surfaceless_query extension is enabled, the value returned in supportsProtected will be identical for every valid surface created on this physical device, and so in the vkGetPhysicalDeviceSurfaceCapabilities2KHR call, VkPhysicalDeviceSurfaceInfo2KHR::surface can be VK_NULL_HANDLE. In that case, the contents of VkSurfaceCapabilities2KHR::surfaceCapabilities as well as any other struct chained to it will be undefined.

Valid Usage (Implicit)
• VUID-VkSurfaceProtectedCapabilitiesKHR-sType-sType
sType must be VK_STRUCTURE_TYPE_SURFACE_PROTECTED_CAPABILITIES_KHR
