VkPresentId2KHR - The list of presentation identifiers

Loading… please wait.

## C Specification

The `VkPresentId2KHR` structure is defined as:

    // Provided by VK_KHR_present_id2
    typedef struct VkPresentId2KHR {
        VkStructureType    sType;
        const void*        pNext;
        uint32_t           swapchainCount;
        const uint64_t*    pPresentIds;
    } VkPresentId2KHR;

## Members

- `sType` is a VkStructureType value identifying this structure.

- `pNext` is `NULL` or a pointer to a structure extending this structure.

- `swapchainCount` is the number of swapchains being presented to the `vkQueuePresentKHR` command.

- `pPresentIds` is `NULL` or a pointer to an array of uint64_t with `swapchainCount` entries. If not `NULL`, each non-zero value in `pPresentIds` specifies the present id to be associated with the presentation of the swapchain with the same index in the vkQueuePresentKHR call.

## Description

For applications to be able to reference specific presentation events queued by a call to `vkQueuePresentKHR`, an identifier needs to be associated with them.

When the VkSurfaceCapabilitiesPresentId2KHR surface capability is present for a surface, applications can include the `VkPresentId2KHR` structure in the `pNext` chain of the VkPresentInfoKHR structure to associate an identifier with each presentation request. The `pPresentIds` provides an identifier for the swapchain present at the corresponding index in VkPresentInfoKHR’s `pSwapchains` array.

If this presentId is non-zero, then the application can later use this value to refer to that image presentation. A value of zero indicates that this presentation has no associated presentId. A non-zero presentId must be greater than any non-zero presentId passed previously by the application for the same swapchain.

If a non-zero presentId was provided, this may be used with vkWaitForPresent2KHR for the application to synchronize against the presentation engine’s processing of the presentation request.

Note | The ID namespace used by this extension must be shared with other extensions that allow the application to provide a 64-bit monotonically increasing presentation ID, such as the original VK_KHR_present_id. This is to allow existing extensions that depend on VK_KHR_present_id to use VK_KHR_present_id2 provided IDs without change, as well as to simplify writing future extensions that require application provided presentation IDs.

Valid Usage

- VUID-VkPresentId2KHR-swapchainCount-10818
  `swapchainCount` must be the same value as `VkPresentInfoKHR`::`swapchainCount`, where this `VkPresentId2KHR` is in the `pNext` chain of the `VkPresentInfoKHR` structure

- VUID-VkPresentId2KHR-presentIds-10819
  Each `presentIds` entry must be greater than any previous `presentIds` entry passed for the associated `pSwapchains` entry

- VUID-VkPresentId2KHR-None-10820
  The swapchain must have been created with `VK_SWAPCHAIN_CREATE_PRESENT_ID_2_BIT_KHR` bit set in the `VkSwapchainCreateFlagBitsKHR` field

Valid Usage (Implicit)

- VUID-VkPresentId2KHR-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_PRESENT_ID_2_KHR`

- VUID-VkPresentId2KHR-pPresentIds-parameter
  If `pPresentIds` is not `NULL`, `pPresentIds` must be a valid pointer to an array of `swapchainCount` `uint64_t` values

- VUID-VkPresentId2KHR-swapchainCount-arraylength
  `swapchainCount` must be greater than `0`
