# VkPhysicalDeviceZeroInitializeWorkgroupMemoryFeaturesKHR(3) Manual Page

## Name

VkPhysicalDeviceZeroInitializeWorkgroupMemoryFeaturesKHR - Structure describing support for zero initialization of workgroup memory by an implementation

Loading… please wait.

## C Specification

The `VkPhysicalDeviceZeroInitializeWorkgroupMemoryFeaturesKHR` structure is defined as:

    // Provided by VK_KHR_zero_initialize_workgroup_memory
    typedef struct VkPhysicalDeviceZeroInitializeWorkgroupMemoryFeaturesKHR {
        VkStructureType    sType;
        void*              pNext;
        VkBool32           shaderZeroInitializeWorkgroupMemory;
    } VkPhysicalDeviceZeroInitializeWorkgroupMemoryFeaturesKHR;

## Members

This structure describes the following feature:

## Description

- `shaderZeroInitializeWorkgroupMemory` specifies whether the implementation supports initializing a variable in Workgroup storage class.

If the `VkPhysicalDeviceZeroInitializeWorkgroupMemoryFeaturesKHR` structure is included in the `pNext` chain of the VkPhysicalDeviceFeatures2 structure passed to vkGetPhysicalDeviceFeatures2, it is filled in to indicate whether each corresponding feature is supported. `VkPhysicalDeviceZeroInitializeWorkgroupMemoryFeaturesKHR` can also be used in the `pNext` chain of VkDeviceCreateInfo to selectively enable these features.

Valid Usage (Implicit)

- VUID-VkPhysicalDeviceZeroInitializeWorkgroupMemoryFeaturesKHR-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_ZERO_INITIALIZE_WORKGROUP_MEMORY_FEATURES_KHR`
