VkPhysicalDeviceHostImageCopyFeatures(3)

# VkPhysicalDeviceHostImageCopyFeatures(3) Manual Page

## Name

VkPhysicalDeviceHostImageCopyFeatures - Structure indicating support for copies to or from images from host memory

## C Specification

The `VkPhysicalDeviceHostImageCopyFeatures` structure is defined as:

    // Provided by VK_VERSION_1_4
    typedef struct VkPhysicalDeviceHostImageCopyFeatures {
        VkStructureType    sType;
        void*              pNext;
        VkBool32           hostImageCopy;
    } VkPhysicalDeviceHostImageCopyFeatures;

    // Provided by VK_EXT_host_image_copy
    // Equivalent to VkPhysicalDeviceHostImageCopyFeatures
    typedef VkPhysicalDeviceHostImageCopyFeatures VkPhysicalDeviceHostImageCopyFeaturesEXT;

## Members

This structure describes the following feature:

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

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

## Description

- `hostImageCopy` indicates that the implementation supports copying from host memory to images using the vkCopyMemoryToImage command, copying from images to host memory using the vkCopyImageToMemory command, and copying between images using the vkCopyImageToImage command.

If the `VkPhysicalDeviceHostImageCopyFeatures` 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 `VkPhysicalDeviceHostImageCopyFeatures`, 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-VkPhysicalDeviceHostImageCopyFeatures-sType-sType
  `sType` must be VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_HOST_IMAGE_COPY_FEATURES

Structure Chaining
