# vkGetLatencyTimingsNV(3) Manual Page

## Name

vkGetLatencyTimingsNV - Get latency marker results

Loading… please wait.

## C Specification

To get an array containing the newest collected latency data, call:

    // Provided by VK_NV_low_latency2
    void vkGetLatencyTimingsNV(
        VkDevice                                    device,
        VkSwapchainKHR                              swapchain,
        VkGetLatencyMarkerInfoNV*                   pLatencyMarkerInfo);

## Parameters

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

- `swapchain` is the swapchain to return data from.

- `pLatencyMarkerInfo` is a pointer to a VkGetLatencyMarkerInfoNV structure specifying the parameters for returning latency information.

## Description

The timings returned by `vkGetLatencyTimingsNV` contain the timestamps requested from vkSetLatencyMarkerNV and additional implementation-specific markers defined in VkLatencyTimingsFrameReportNV.

Valid Usage (Implicit)

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

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

- VUID-vkGetLatencyTimingsNV-pLatencyMarkerInfo-parameter
  `pLatencyMarkerInfo` must be a valid pointer to a VkGetLatencyMarkerInfoNV structure

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