# vkGetPhysicalDeviceDisplayPlanePropertiesKHR(3) Manual Page

## Name

vkGetPhysicalDeviceDisplayPlanePropertiesKHR - Query the plane properties

Loading… please wait.

## C Specification

Images are presented to individual planes on a display. Devices must support at least one plane on each display. Planes can be stacked and blended to composite multiple images on one display. Devices may support only a fixed stacking order and fixed mapping between planes and displays, or they may allow arbitrary application-specified stacking orders and mappings between planes and displays. To query the properties of device display planes, call:

    // Provided by VK_KHR_display
    VkResult vkGetPhysicalDeviceDisplayPlanePropertiesKHR(
        VkPhysicalDevice                            physicalDevice,
        uint32_t*                                   pPropertyCount,
        VkDisplayPlanePropertiesKHR*                pProperties);

## Parameters

- `physicalDevice` is a physical device.

- `pPropertyCount` is a pointer to an integer related to the number of display planes available or queried, as described below.

- `pProperties` is either `NULL` or a pointer to an array of `VkDisplayPlanePropertiesKHR` structures.

## Description

If `pProperties` is `NULL`, then the number of display planes available for `physicalDevice` is returned in `pPropertyCount`. Otherwise, `pPropertyCount` must point to a variable set by the application to the number of elements in the `pProperties` array, and on return the variable is overwritten with the number of structures actually written to `pProperties`. If the value of `pPropertyCount` is less than the number of display planes for `physicalDevice`, at most `pPropertyCount` structures will be written.

Valid Usage (Implicit)

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

- VUID-vkGetPhysicalDeviceDisplayPlanePropertiesKHR-pPropertyCount-parameter
  `pPropertyCount` must be a valid pointer to a `uint32_t` value

- VUID-vkGetPhysicalDeviceDisplayPlanePropertiesKHR-pProperties-parameter
  If the value referenced by `pPropertyCount` is not `0`, and `pProperties` is not `NULL`, `pProperties` must be a valid pointer to an array of `pPropertyCount` VkDisplayPlanePropertiesKHR structures

Return Codes

On success, this command returns

  - `VK_SUCCESS`

  - `VK_INCOMPLETE`

On failure, this command returns

  - `VK_ERROR_OUT_OF_HOST_MEMORY`

  - `VK_ERROR_OUT_OF_DEVICE_MEMORY`
