| === Description |
| |
| 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. |
