This extension extends slink:VkSurfaceCapabilities2KHR, providing
applications a way to query whether swapchains can: be created with the
ename:VK_SWAPCHAIN_CREATE_PROTECTED_BIT_KHR flag set.
Vulkan 1.1 added (optional) support for protect memory and protected
resources including buffers (ename:VK_BUFFER_CREATE_PROTECTED_BIT), images
(ename:VK_IMAGE_CREATE_PROTECTED_BIT), and swapchains
(ename:VK_SWAPCHAIN_CREATE_PROTECTED_BIT_KHR).
However, on implementations which support multiple windowing systems, not
all window systems may: be able to provide a protected display path.
This extension provides a way to query if a protected swapchain created for
a surface (and thus a specific windowing system) can: be displayed on
screen.
It extends the existing slink:VkSurfaceCapabilities2KHR structure with a new
slink:VkSurfaceProtectedCapabilitiesKHR structure from which the application
can: obtain information about support for protected swapchain creation
through flink:vkGetPhysicalDeviceSurfaceCapabilities2KHR.
