# vkGetPhysicalDeviceScreenPresentationSupportQNX(3) Manual Page

## Name

vkGetPhysicalDeviceScreenPresentationSupportQNX - Query physical device for presentation to QNX Screen

Loading… please wait.

## C Specification

To determine whether a queue family of a physical device supports presentation to a QNX Screen compositor, call:

    // Provided by VK_QNX_screen_surface
    VkBool32 vkGetPhysicalDeviceScreenPresentationSupportQNX(
        VkPhysicalDevice                            physicalDevice,
        uint32_t                                    queueFamilyIndex,
        struct _screen_window*                      window);

## Parameters

- `physicalDevice` is the physical device.

- `queueFamilyIndex` is the queue family index.

- `window` is the QNX Screen `window` object.

## Description

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

Valid Usage

- VUID-vkGetPhysicalDeviceScreenPresentationSupportQNX-queueFamilyIndex-04743
  `queueFamilyIndex` must be less than `pQueueFamilyPropertyCount` returned by `vkGetPhysicalDeviceQueueFamilyProperties` for the given `physicalDevice`

Valid Usage (Implicit)

- VUID-vkGetPhysicalDeviceScreenPresentationSupportQNX-physicalDevice-parameter
  `physicalDevice` must be a valid VkPhysicalDevice handle

- VUID-vkGetPhysicalDeviceScreenPresentationSupportQNX-window-parameter
  `window` must be a valid pointer to a `_screen_window` value
