# vkGetPhysicalDeviceDirectFBPresentationSupportEXT(3) Manual Page

## Name

vkGetPhysicalDeviceDirectFBPresentationSupportEXT - Query physical device for presentation with DirectFB

Loading… please wait.

## 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
