# VkLatencySleepInfoNV(3) Manual Page

## Name

VkLatencySleepInfoNV - Structure specifying the parameters of vkLatencySleepNV

Loading… please wait.

## C Specification

The `VkLatencySleepInfoNV` structure is defined as:

    // Provided by VK_NV_low_latency2
    typedef struct VkLatencySleepInfoNV {
        VkStructureType    sType;
        const void*        pNext;
        VkSemaphore        signalSemaphore;
        uint64_t           value;
    } VkLatencySleepInfoNV;

## Members

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

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

- `signalSemaphore` is a semaphore that is signaled to indicate that the application should resume input sampling work.

- `value` is the value that `signalSemaphore` is set to for resuming sampling work.

## Description

Valid Usage

- VUID-VkLatencySleepInfoNV-signalSemaphore-09361
  `signalSemaphore` must be a timeline semaphore

Valid Usage (Implicit)

- VUID-VkLatencySleepInfoNV-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_LATENCY_SLEEP_INFO_NV`

- VUID-VkLatencySleepInfoNV-signalSemaphore-parameter
  `signalSemaphore` must be a valid VkSemaphore handle
