## Name

vkGetPhysicalDeviceXcbPresentationSupportKHR - Query physical device for presentation to X11 server using XCB

Loading… please wait.

## C Specification

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

    // Provided by VK_KHR_xcb_surface
    VkBool32 vkGetPhysicalDeviceXcbPresentationSupportKHR(
        VkPhysicalDevice                            physicalDevice,
        uint32_t                                    queueFamilyIndex,
        xcb_connection_t*                           connection,
        xcb_visualid_t                              visual_id);

## Parameters

- `physicalDevice` is the physical device.

- `queueFamilyIndex` is the queue family index.

- `connection` is a pointer to an `xcb_connection_t` to the X server.

- `visual_id` is an X11 visual (`xcb_visualid_t`).

## Description

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

Valid Usage

- VUID-vkGetPhysicalDeviceXcbPresentationSupportKHR-queueFamilyIndex-01312
  `queueFamilyIndex` must be less than `pQueueFamilyPropertyCount` returned by `vkGetPhysicalDeviceQueueFamilyProperties` for the given `physicalDevice`

Valid Usage (Implicit)

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

- VUID-vkGetPhysicalDeviceXcbPresentationSupportKHR-connection-parameter
  `connection` must be a valid pointer to an `xcb_connection_t` value
