Description

The VK_EXT_directfb_surface extension is an instance extension. It provides a mechanism to create a SurfaceKHR object (defined by the VK_KHR_surface extension) that refers to a DirectFB IDirectFBSurface, as well as a query to determine support for rendering via DirectFB.

valuecreateDirectFBSurfaceEXT
  1. :: MonadIO io
  2. => Instance

    instance is the instance to associate the surface with.

  3. -> DirectFBSurfaceCreateInfoEXT

    pCreateInfo is a pointer to a DirectFBSurfaceCreateInfoEXT structure containing parameters affecting the creation of the surface object.

  4. -> "allocator" ::: Maybe AllocationCallbacks

    pAllocator is the allocator used for host memory allocated for the surface object when there is no more specific allocator available (see Memory Allocation).

valuegetPhysicalDeviceDirectFBPresentationSupportEXT
  1. :: MonadIO io
  2. => PhysicalDevice

    physicalDevice is the physical device.

    physicalDevice must be a valid PhysicalDevice handle

  3. -> "queueFamilyIndex" ::: Word32

    queueFamilyIndex is the queue family index.

    queueFamilyIndex must be less than pQueueFamilyPropertyCount returned by getPhysicalDeviceQueueFamilyProperties for the given physicalDevice

  4. -> "dfb" ::: Ptr IDirectFB

    dfb is a pointer to the IDirectFB main interface of DirectFB.

    dfb must be a valid pointer to an IDirectFB value

VkSurfaceKHR - Opaque handle to a surface object

Description

The VK_KHR_surface extension declares the SurfaceKHR object, and provides a function for destroying SurfaceKHR objects. Separate platform-specific extensions each provide a function for creating a SurfaceKHR object for the respective platform. From the application’s perspective this is an opaque handle, just like the handles of other Vulkan objects.
