# vkAcquireFullScreenExclusiveModeEXT(3) Manual Page

## Name

vkAcquireFullScreenExclusiveModeEXT - Acquire full-screen exclusive mode for a swapchain

Loading… please wait.

## C Specification

To acquire exclusive full-screen access for a swapchain, call:

    // Provided by VK_EXT_full_screen_exclusive
    VkResult vkAcquireFullScreenExclusiveModeEXT(
        VkDevice                                    device,
        VkSwapchainKHR                              swapchain);

## Parameters

- `device` is the device associated with `swapchain`.

- `swapchain` is the swapchain to acquire exclusive full-screen access for.

## Description

Valid Usage

- VUID-vkAcquireFullScreenExclusiveModeEXT-swapchain-02674
  `swapchain` must not be in the retired state

- VUID-vkAcquireFullScreenExclusiveModeEXT-swapchain-02675
  `swapchain` must be a swapchain created with a VkSurfaceFullScreenExclusiveInfoEXT structure, with `fullScreenExclusive` set to `VK_FULL_SCREEN_EXCLUSIVE_APPLICATION_CONTROLLED_EXT`

- VUID-vkAcquireFullScreenExclusiveModeEXT-swapchain-02676
  `swapchain` must not currently have exclusive full-screen access

A return value of `VK_SUCCESS` indicates that the `swapchain` successfully acquired exclusive full-screen access. The swapchain will retain this exclusivity until either the application releases exclusive full-screen access with vkReleaseFullScreenExclusiveModeEXT, destroys the swapchain, or if any of the swapchain commands return `VK_ERROR_FULL_SCREEN_EXCLUSIVE_MODE_LOST_EXT` indicating that the mode was lost because of platform-specific changes.

If the swapchain was unable to acquire exclusive full-screen access to the display then `VK_ERROR_INITIALIZATION_FAILED` is returned. An application can attempt to acquire exclusive full-screen access again for the same swapchain even if this command fails, or if `VK_ERROR_FULL_SCREEN_EXCLUSIVE_MODE_LOST_EXT` has been returned by a swapchain command.

Valid Usage (Implicit)

- VUID-vkAcquireFullScreenExclusiveModeEXT-device-parameter
  `device` must be a valid VkDevice handle

- VUID-vkAcquireFullScreenExclusiveModeEXT-swapchain-parameter
  `swapchain` must be a valid VkSwapchainKHR handle

- VUID-vkAcquireFullScreenExclusiveModeEXT-swapchain-parent
  `swapchain` must have been created, allocated, or retrieved from `device`

Return Codes

On success, this command returns

  - `VK_SUCCESS`

On failure, this command returns

  - `VK_ERROR_OUT_OF_HOST_MEMORY`

  - `VK_ERROR_OUT_OF_DEVICE_MEMORY`

  - `VK_ERROR_INITIALIZATION_FAILED`

  - `VK_ERROR_SURFACE_LOST_KHR`
