# VkCheckpointDataNV(3) Manual Page

## Name

VkCheckpointDataNV - Return structure for command buffer checkpoint data

Loading… please wait.

## C Specification

The VkCheckpointDataNV structure is defined as:

    // Provided by VK_NV_device_diagnostic_checkpoints
    typedef struct VkCheckpointDataNV {
        VkStructureType            sType;
        void*                      pNext;
        VkPipelineStageFlagBits    stage;
        void*                      pCheckpointMarker;
    } VkCheckpointDataNV;

## Members

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

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

- `stage` is a `VkPipelineStageFlagBits` value specifying which pipeline stage the checkpoint marker data refers to.

- `pCheckpointMarker` contains the value of the last checkpoint marker executed in the stage that `stage` refers to.

## Description

The stages at which a checkpoint marker can be executed are implementation-defined and can be queried by calling vkGetPhysicalDeviceQueueFamilyProperties2.

Valid Usage (Implicit)

- VUID-VkCheckpointDataNV-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_CHECKPOINT_DATA_NV`

- VUID-VkCheckpointDataNV-pNext-pNext
  `pNext` must be `NULL`
