VkPhysicalDeviceTimelineSemaphoreProperties(3)

# VkPhysicalDeviceTimelineSemaphoreProperties(3) Manual Page

## Name

VkPhysicalDeviceTimelineSemaphoreProperties - Structure describing timeline semaphore properties that can be supported by an implementation

Loading… please wait.

## C Specification

The `VkPhysicalDeviceTimelineSemaphoreProperties` structure is defined as:

    // Provided by VK_VERSION_1_2
    typedef struct VkPhysicalDeviceTimelineSemaphoreProperties {
        VkStructureType    sType;
        void*              pNext;
        uint64_t           maxTimelineSemaphoreValueDifference;
    } VkPhysicalDeviceTimelineSemaphoreProperties;

or the equivalent

    // Provided by VK_KHR_timeline_semaphore
    typedef VkPhysicalDeviceTimelineSemaphoreProperties VkPhysicalDeviceTimelineSemaphorePropertiesKHR;

## Members

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

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

## Description

- `maxTimelineSemaphoreValueDifference` indicates the maximum difference allowed by the implementation between the current value of a timeline semaphore and any pending signal or wait operations.

If the `VkPhysicalDeviceTimelineSemaphoreProperties` structure is included in the `pNext` chain of the VkPhysicalDeviceProperties2 structure passed to vkGetPhysicalDeviceProperties2, it is filled in with each corresponding implementation-dependent property.

Valid Usage (Implicit)

- VUID-VkPhysicalDeviceTimelineSemaphoreProperties-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_TIMELINE_SEMAPHORE_PROPERTIES`
