C Specification

To acquire an available presentable image to use, and retrieve the index of that image, call:

// Provided by VK_VERSION_1_1 with VK_KHR_swapchain
VkResult vkAcquireNextImage2KHR(
    VkDevice                                    device,
    const VkAcquireNextImageInfoKHR*            pAcquireInfo,
    uint32_t*                                   pImageIndex);

Parameters

  • device is the device associated with swapchain.

  • pAcquireInfo is a pointer to a VkAcquireNextImageInfoKHR structure containing parameters of the acquire.

  • pImageIndex is a pointer to a uint32_t value specifying the index of the next image to use.

Description

If VkPhysicalDeviceVulkanSC10Properties::deviceNoDynamicHostAllocations is VK_TRUE, vkAcquireNextImage2KHR must not return VK_ERROR_OUT_OF_HOST_MEMORY.

Valid Usage

  • VUID-vkAcquireNextImage2KHR-surface-07784
    If forward progress cannot be guaranteed for the surface used to create swapchain, the timeout member of pAcquireInfo must not be UINT64_MAX

Valid Usage (Implicit)

  • VUID-vkAcquireNextImage2KHR-device-parameter
    device must be a valid VkDevice handle

  • VUID-vkAcquireNextImage2KHR-pAcquireInfo-parameter
    pAcquireInfo must be a valid pointer to a valid VkAcquireNextImageInfoKHR structure

  • VUID-vkAcquireNextImage2KHR-pImageIndex-parameter
    pImageIndex must be a valid pointer to a uint32_t value

Return Codes
On success, this command returns

  • VK_SUCCESS

  • VK_TIMEOUT

  • VK_NOT_READY

  • VK_SUBOPTIMAL_KHR

On failure, this command returns

  • VK_ERROR_OUT_OF_HOST_MEMORY

  • VK_ERROR_OUT_OF_DEVICE_MEMORY

  • VK_ERROR_DEVICE_LOST

  • VK_ERROR_OUT_OF_DATE_KHR

  • VK_ERROR_SURFACE_LOST_KHR
