Class KHRXlibSurface


  • public class KHRXlibSurface
    extends java.lang.Object
    The VK_KHR_xlib_surface extension is an instance extension. It provides a mechanism to create a VkSurfaceKHR object (defined by the VK_KHR_surface extension) that refers to an X11 Window, using the Xlib client-side library, as well as a query to determine support for rendering via Xlib.

        Create a VkSurfaceKHR object for an X11 window, using the Xlib client-side library.
        C Specification

        To create a VkSurfaceKHR object for an X11 window, using the Xlib client-side library, call:

        
         VkResult vkCreateXlibSurfaceKHR(
             VkInstance                                  instance,
             const VkXlibSurfaceCreateInfoKHR*           pCreateInfo,
             const VkAllocationCallbacks*                pAllocator,
             VkSurfaceKHR*                               pSurface);
        Valid Usage (Implicit)
        • instance must be a valid VkInstance handle
        • pCreateInfo must be a valid pointer to a valid VkXlibSurfaceCreateInfoKHR structure
        • If pAllocator is not NULL, pAllocator must be a valid pointer to a valid VkAllocationCallbacks structure
        • pSurface must be a valid pointer to a VkSurfaceKHR handle
        Return Codes
        On success, this command returns
        On failure, this command returns

        VkAllocationCallbacks, VkXlibSurfaceCreateInfoKHR

        Parameters:
        instance - the instance to associate the surface with.
        pCreateInfo - a pointer to an instance of the VkXlibSurfaceCreateInfoKHR structure containing the parameters affecting the creation of the surface object.
        pAllocator - the allocator used for host memory allocated for the surface object when there is no more specific allocator available (see Memory Allocation).
        pSurface - points to a VkSurfaceKHR handle in which the created surface object is returned.

        Query physical device for presentation to X11 server using Xlib.
        C Specification

        To determine whether a queue family of a physical device supports presentation to an X11 server, using the Xlib client-side library, call:

        
         VkBool32 vkGetPhysicalDeviceXlibPresentationSupportKHR(
             VkPhysicalDevice                            physicalDevice,

             VisualID                                    visualID);
        Description

        This platform-specific function can be called prior to creating a surface.

        Valid Usage
        Valid Usage (Implicit)
        • physicalDevice must be a valid VkPhysicalDevice handle
        • dpy must be a valid pointer to a Display value
        Parameters:
        physicalDevice - the physical device.
        queueFamilyIndex - the queue family index.
        dpy - a pointer to an Xlib Display connection to the server.
