# VkPhysicalDeviceZeroInitializeDeviceMemoryFeaturesEXT(3) Manual Page

## Name

VkPhysicalDeviceZeroInitializeDeviceMemoryFeaturesEXT - Structure describing whether the implementation supports cleared allocation functionality

Loading… please wait.

## C Specification

The `VkPhysicalDeviceZeroInitializeDeviceMemoryFeaturesEXT` structure is defined as:

    // Provided by VK_EXT_zero_initialize_device_memory
    typedef struct VkPhysicalDeviceZeroInitializeDeviceMemoryFeaturesEXT {
        VkStructureType    sType;
        void*              pNext;
        VkBool32           zeroInitializeDeviceMemory;
    } VkPhysicalDeviceZeroInitializeDeviceMemoryFeaturesEXT;

## Members

This structure describes the following features:

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

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

- `zeroInitializeDeviceMemory` indicates that the implementation supports zeroing memory allocations using a user-specified flag.

## Description

If the `VkPhysicalDeviceZeroInitializeDeviceMemoryFeaturesEXT` 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. If the application wishes to use a VkDevice with any features described by `VkPhysicalDeviceZeroInitializeDeviceMemoryFeaturesEXT`, it must add an instance of the structure, with the desired feature members set to VK_TRUE, to the `pNext` chain of VkDeviceCreateInfo when creating the VkDevice.

Valid Usage (Implicit)

- VUID-VkPhysicalDeviceZeroInitializeDeviceMemoryFeaturesEXT-sType-sType
  `sType` must be VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_ZERO_INITIALIZE_DEVICE_MEMORY_FEATURES_EXT
