C Specification

To determine whether a queue family of a physical device supports presentation with DirectFB library, call:

// Provided by VK_EXT_directfb_surface
VkBool32 vkGetPhysicalDeviceDirectFBPresentationSupportEXT(
    VkPhysicalDevice                            physicalDevice,
    uint32_t                                    queueFamilyIndex,
    IDirectFB*                                  dfb);

Parameters

  • physicalDevice is the physical device.

  • queueFamilyIndex is the queue family index.

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

Description

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

Valid Usage
  • VUID-vkGetPhysicalDeviceDirectFBPresentationSupportEXT-queueFamilyIndex-04119
    queueFamilyIndex must be less than pQueueFamilyPropertyCount returned by vkGetPhysicalDeviceQueueFamilyProperties for the given physicalDevice

Valid Usage (Implicit)
  • VUID-vkGetPhysicalDeviceDirectFBPresentationSupportEXT-physicalDevice-parameter
    physicalDevice must be a valid VkPhysicalDevice handle

  • VUID-vkGetPhysicalDeviceDirectFBPresentationSupportEXT-dfb-parameter
    dfb must be a valid pointer to an IDirectFB value
