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
